Cyborg Cockroach Sparks Ethics Debate

first_imgIf you are seeing a shark video above, please try viewing it in a different browser.At the TEDx conference in Detroit last week, RoboRoach #12 scuttled across the exhibition floor, pursued not by an exterminator but by a gaggle of fascinated onlookers. Wearing a tiny backpack of microelectronics on its shell, the cockroach—a member of the Blaptica dubia species—zigzagged along the corridor in a twitchy fashion, its direction controlled by the brush of a finger against an iPhone touch screen (as seen in video above).RoboRoach #12 and its brethren are billed as a do-it-yourself neuroscience experiment that allows students to create their own “cyborg” insects. The roach was the main feature of the TEDx talk by Greg Gage and Tim Marzullo, co-founders of an educational company called Backyard Brains. After a summer Kickstarter campaign raised enough money to let them hone their insect creation, the pair used the Detroit presentation to show it off and announce that starting in November, the company will, for $99, begin shipping live cockroaches across the nation, accompanied by a microelectronic hardware and surgical kits geared toward students as young as 10 years old.That news, however, hasn’t been greeted warmly by everyone. Gage and Marzullo, both trained as neuroscientists and engineers, say that the purpose of the project is to spur a “neuro-revolution” by inspiring more kids to join the fields when they grow up, but some critics say the project is sending the wrong message. “They encourage amateurs to operate invasively on living organisms” and “encourage thinking of complex living organisms as mere machines or tools,” says Michael Allen Fox, a professor of philosophy at Queen’s University in Kingston, Canada.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)“It’s kind of weird to control via your smartphone a living organism,” says William Newman, a presenter at TEDx and managing principal at the Newport Consulting Group, who got to play with a RoboRoach at the conference. At the same time, he says, he is pleased that the project will teach students about the neuroscience behind brain stimulation treatments that are being used to treat two of his friends with Parkinson’s disease.The roaches’ movements to the right or left are controlled by electrodes that feed into their antennae and receive signals by remote control—via the Bluetooth signals emitted by smartphones. To attach the device to the insect, students are instructed to douse the insect in ice water to “anesthetize” it, sand a patch of shell on its head so that the superglue and electrodes will stick, and then insert a groundwire into the insect’s thorax. Next, they must carefully trim the insect’s antennae, and insert silver electrodes into them. Ultimately, these wires receive electrical impulses from a circuit affixed to the insect’s back.Gage says the roaches feel little pain from the stimulation, to which they quickly adapt. But the notion that the insects aren’t seriously harmed by having body parts cut off is “disingenuous,” says animal behavior scientist Jonathan Balcombe of the Humane Society University in Washington, D.C. “If it was discovered that a teacher was having students use magnifying glasses to burn ants and then look at their tissue, how would people react?”Gage says that in his experience, working carefully and closely with insects and other animals in experiments can sensitize students to the fact that roaches “are actually similar to us and have the same neurons that we have.” He also notes that the company doesn’t kill their own roaches after the experiments, but sends them to a “retirement” tank that the team calls Shady Acres. Although they may be missing legs or antennae, the insects tend to get on with their lives after the experiments, he says. “They do what they like to do: make babies, eat, and poop.”“I try not to downplay the fact that in science we use animal models and a lot of times they are killed,” Gage says. “As scientists, we do this all the time, but it happens behind closed doors.” By following the surgical instructions, he says, all students learn that they have to care for the roaches—treating wounds by “putting a little Vaseline” on them, and minimizing suffering whenever possible. Still, Gage acknowledges, “we get a lot of e-mails telling us we’re teaching kids to be psychopaths.”The RoboRoach “gives you a way of playing with living things,” like a short-lived version of the forbidden “Imperius Curse” in the Harry Potter novels, says bioethicist Gregory Kaebnick of the Hastings Center in Garrison, New York. He finds the product “unpleasant,” but adds that he won’t be calling for a boycott, either. “I’ll just be happy that I found a cleverly marketed consumer item that I am very happy not to own.”last_img read more

Ashes 2017: Australia recall Ashton Agar to bolster spin arsenal for Sydney Test

first_imgAustralia are all set to attack England with two spinners in the fifth and final Test of the Ashes series at Sydney which is why off-spinner Ashton Agar has been recalled into the 14-man squad.The left-arm spinner was given the nod ahead of Steve O’Keefe and Jon Holland as a possible partner for Australia’s first-choice spinner Nathan Lyon for the series finale.Lyon has been the lone spinner in the Australian XI so far in the four Tests and he has been a vital cog in the wheel for the hosts who regained the Ashes after their win at Perth.Lyon has picked up 17 wickets in the four matches at an average of 27.88 and is the third-highest wicket-taker in the series behind Mitchell Starc (19) and Josh Hazlewood (18).WATCH VIKTOR AXELSEN INTERVIEWStarc, who missed the ongoing Boxing Day Test due to a heel injury, and middle order batsman Peter Handscomb, who was dropped from the side after the second Adelaide Test, have been retained in the 14-man squad.Agar broke a finger during Australia’s limited-overs tour of India in September but returned to domestic action earlier this month.The 24-year-old last played a Test match against Bangladesh in Chittagong in September.If Starc proves his fitness, Agar could be included at the expense of seam bowling all-rounder Mitchell Marsh.Agar’s inclusion will fan speculation that 33-year-old left-arm spinner Steve O’Keefe’s international career is over despite his appearance in five tests on the subcontinent this year and his match-winning 12-wicket haul against India in Pune.advertisementO’Keefe was belatedly called up for the Bangladesh tour after paceman Josh Hazlewood was ruled out of the Chittagong test with a side strain, but selectors have made no secret of their desire to look to groom a young spinner for the long term.Australia squad: Steve Smith (captain), David Warner, Cameron Bancroft, Usman Khawaja, Shaun Marsh, Mitchell Marsh, Tim Paine, Pat Cummins, Josh Hazlewood, Nathan Lyon, Jackson Bird, Mitchell Starc, Ashton Agar, Peter Handscomb.(With Reuters Inputs)last_img read more

Registration Fairs for Disabled Persons Underway

first_img An additional 6500 persons with varying degrees of disabilities have been added to the Jamaica Council for Persons with Disabilities (JCPD) database, through a series of islandwide registration fairs, currently underway.The initiative, which began on July 22, forms part of the Council’s thrust to enhance its outreach programme to disabled persons across the society.Executive Director of the JCPD, Christine Hendricks, informs that there are many disabled persons islandwide, who are unable to access the range of available services available to them, consequent on where they reside, or because they are unaware of these provisions.Against this background, she says the JCPD has embarked on the registration fairs through which they are targeting to increase the current number of beneficiaries on the agency’s database to upwards of 50,000.“We want persons with disabilities to know that it is important to register with the Council, and for us to have the numbers to be able to plan effectively so they can access the services available,” Mrs. Hendricks says.These services include: skills training; job placements; job coaching; housing benefits; the provision of rehabilitation grants for persons interested in starting small businesses; and a bus pass service, at a concessionary rate of $20, on Jamaica Urban Transit Company (JUTC) buses.Other provisions include: assistive aids; school related assistance; and an economic empowerment grant, provided to persons capable of managing a serious business venture, which ranges from $150,000 up to $400.000, if they are applying for assistance as a group.Mrs. Hendricks informs that, to date, the Council has conducted registrations in Hanover, St James, Trelawny, St. Ann, and St. Mary, and will continue its drive, in the other parishes, until August 29.The process continues on Monday, August 12, when the JCPD team goes to St. Thomas Technical High School, and Orange Walk in Golden Grove, St. Thomas.The drive continues on Tuesday and Wednesday, August 13 and 14, at the Santa Cruz Primary and Junior High School, and Black River Primary School respectively, in St. Elizabeth.Registrations will be conducted in Manchester at St. Mark’s Anglican Church and Mandeville Parish Church on Thursday August 14 and at Christiana High School on August 15.The following week will see registration sessions at the following locations: St Gabriel’s Anglican Church, May Pen – August 19, and  Clarendon College – August 20, Clarendon;  and Linstead Anglican Church; Emanuel Apostolic Church; and Spanish Town Methodist in St. Catherine, on August 21, 22, and 23, respectively.The drive moves next to Kingston and St. Andrew, and will be held at Genesis Academy, and Stony Hill Primary and Junior High School on August 26, and Emancipation Park, on August 27. It continues in Portland, at Lynch Park, Buff Bay, on August 28, and concludes at Folly Oval, Port Antonio, on August 29.“The aim of this mass registration drive is to have an idea of the number of persons with disabilities that are living in Jamaica, so that we can provide for them effectively. We want to help as much persons as possible, because there are services available that can enrich the lives of persons with disabilities in Jamaica,” the JCPD Executive Director tells JIS News.Mrs. Hendricks says persons with disabilities desirous of registering with the Council are required to have valid identification, a birth certificate, and Taxpayer Registration Number (TRN).“If they do not have their birth certificates or TRN, they can still come to the fair, and we will assist them as best as possible. The first 25 persons who do not have a birth certificate, will receive a free copy, free of cost, compliments of the Registrar General’s Department (RGD), which will make way for all the other required documents. The others will have to pay the regular fee of $850,” she outlines.She advises that Tax Administration of Jamaica (TAJ) will also be at the various locations, to assist with the registration process, by providing TRNs to persons not in possession of same.Additionally, she says HEART Trust/NTA, which has been integral in the process, will also be present to provide information on training opportunities that persons with disabilities can access.Where persons are unable to attend the registration fairs because of physical or financial challenges, community based officers, dispatched to the various parishes, will be conducting home visits, as part of the drive.Mrs. Hendricks is encouraging family members, caregivers, and neighbours to be apprize themselves of the dates when the JCPD’s fairs will be held in the various parishes, and ensure that the persons in their care are registered and thus enabling them to take advantage of the various benefits available to them.For further information on the JCPD fairs and other activities, persons can contact the agency at 926-9374-5 or 447-0444. 6500 persons with varying degrees of disabilities have been added to the JCPD database These services include: skills training; job placements; job coaching; housing benefits, etc. Story Highlights Registration fairs to bring this number up to 50,000 last_img read more

New Route Chosen for Coke Ovens Brook

first_imgAn engineering report on the Tar Ponds and Coke Ovens cleanuprecommends rerouting Coke Ovens Brook along two branches. Previous studies recommended moving the brook to an area where itwill not pick up contaminated groundwater as it passes throughthe Coke Ovens site. Moving the brook will also permit a morethorough cleanup of the stream bed, where contaminantsaccumulated during a century of coke production. The full report of the conceptual design by the engineering firmsDillon Consulting Ltd. and Franz Environmental Inc. is availableon the Sydney Tar Ponds Agency website at www.gov.ns.ca/STPA/reports/Coke_Ovens_Brook_Realignment_2004.pdf . The Sydney Tar Ponds Agency will commission a detailedengineering design of the realignment, and conduct anenvironmental screening. Work on the project will begin in thesummer of 2005. “This is an exciting development,” said Richard Morykot, theSydney Tar Ponds Agency engineer who supervised the project.”It’s the first concrete step in the big cleanup.” The newly realigned brook will have two branches. The south branch will start at the outflow from the MAID Pond,behind the Schwartz building on Vulcan Avenue. It will run alongthe southern boundary of the Coke Ovens site, parallel to VulcanAvenue, through an area known as Mullin’s Bank. Near the westernboundary of the site, the brook will merge with Cagney Brook andrun north, parallel to Victoria Road, and then follow theexisting channel under the Victoria Road overpass. The north branch will run along the Whitney Pier side of theSydney Coal Railway track and the SPAR road, picking up flowsfrom several smaller brooks along the way. It will cross underthe tracks and the Spar Road at a point just east of Lingan Road,and follow the rail spur through the Coke Ovens site to join thesouth branch at the Victoria Road overpass. Part of the relocated south branch will be piped underground, andportions of both branches will be lined with synthetic materialor clay to prevent recontamination. Engineering work continues on three other projects that have beenadvanced to prevent environmental damage while the cleanupundergoes mandatory environmental assessment. The projectsinclude the construction of a coffer dam at Battery Point, theclean up of the cooling pond at the southwest corner of the Syscoproperty, and the relocation of the Victoria Road water main. The report was funded under the 1999 federal-provincial-municipalcost share agreement for the Tar Ponds and Coke Ovens cleanup.last_img read more

David De Gea Hopes to Make His Comeback Against Liverpool

Miami – After a smooth with his national team against Macedonia, Manchester United’s, David De Gea, feels hopeful about making his official comeback in the Liverpool match on Saturday.According to UK’s Express, Tuesday was a good night for goalkeeper De Gea in his “first competitive appearance of the season” When Spain won to Macedonia for the Euro 2016 qualifiers.United’s Coach, Vicente del Bosque, favored him over Iker Casillas. “I felt well. The coach has given me confidence,” De Gea said.This victory comes at a perfect time for De Gea since he was finally able to have a “clear-the-air” talk with United’s Manager Louis Van Gaal regarding his inclusion in the match against Liverpool. Reportedly, this was the first time both men spoke after their controversial feud.Van Gaal has previously claimed the Spanish goalkeeper was too distracted with his failed move to Real Madrid and he doubted his desire to be with Man United. “I wanted to play and now we’ll see after the international break if I’m lucky with my club. I’m calm. I’ll keep working and improving – in short, I’m enjoying my football and I’m happy,” he said.De Gea has been receiving lots of support from his teammates and he has publicly expressed his gratitude toward them.United’s Ander Herrera mentioned several positive traits about him, “For me, he [David] is the best goalkeeper in the world and I think many people think the same. We are happy as a team to have him with us and as a friend I am happy also”.Will De Gea play against Liverpool? We will have to wait and see. It is still in Van Gaal’s hands.© Morocco World News.

UN grants more than 8 million to help in relief effort after

20 August 2007The United Nations today allocated $8.7 million from its Central Emergency Response Fund (CERF) to help the ongoing humanitarian relief efforts in Sudan, where more than 1.5 million people may soon need assistance in the wake of devastating floods. The United Nations today allocated $8.7 million from its Central Emergency Response Fund (CERF) to help the ongoing humanitarian relief efforts in Sudan, where more than 1.5 million people may soon need assistance in the wake of devastating floods. Emergency Relief Coordinator John Holmes announced that he had approved the grant, which will be allocated among 11 relief projects across Sudan, where torrential rainfall has destroyed or seriously damaged more than 30,000 homes and inundated towns, villages and farmlands. At least 150,000 people are now homeless from the floods, and UN agencies have so far supplied aid to over 500,000 people. The east and centre of the country have been hardest hit, especially the states of Gedaref, Kassala, Khartoum, Northern Kordofan, Unity and Upper Nile. But Sudanese authorities have forecast more heavy rains until the end of the annual wet season next month, and Mr. Holmes – who is also Under-Secretary-General for Humanitarian Affairs – said as many 1.5 million people could end up being affected by floods. “Thanks to these funds, we will be able to assist over one and a half million current and potential flood victims, until or beyond the end of the rainy season,” he said.On Friday UN humanitarian agencies said they would soon launch an appeal with their partner non-governmental organizations (NGOs) for more than $10 million to help with the flood relief effort, including providing food aid and ensuring there is safe drinking water. The UN has now allocated about $13.5 million to the response to the Sudanese floods, including an earlier grant of $4.8 million from its locally-managed Common Humanitarian Fund (CHF). The Office of the Resident and Humanitarian Coordinator for Sudan said in a media statement that the CERF funding will be allocated to projects managed by five UN agencies – the Food and Agriculture Organization (FAO), the UN Children’s Fund (UNICEF), the UN Population Fund (UNFPA), the World Food Programme (WFP) and the World Health Organization (WHO). About $4.5 million will be dedicated to providing drugs, health care and support to epidemic surveillance to try to prevent any major disease outbreaks, while $2 million will be spent on ensuring that more than one million people receive clean water or water purification products. Some $1.5 million will be used to provide emergency shelter and non-food items to families who have lost their homes or essential goods, while $700,000 will be given out in food aid and livestock or crop survival programmes. read more

OHCHR needs USD 337800 to implement resolution

The Daily Leader quoted Johannes Huisman, Director of the Office of Programme Planning, Budget and Accounts as saying USD 337,800 will be required for OHCHR Geneva staff to conduct six missions to Colombo of 14 days each and for local transport and other expenses during the field missions,.The funds will also be required to support the review and assessment of progress on implementing the recommendations related to reconciliation, accountability and human rights in Sri Lanka. The Office of Programme Planning, Budget and Accounts says the USD 337,800 is not part of the 2016 – 2017 UN budget so funds have not been allocated for it. In order to obtain the required funds, the UN budget will be revised if the resolution is passed and UN Secretary General Ban Ki-moon will then inform the UN General Assembly during its ongoing 70th session on the additional funds required. Johannes Huisman said that the funds will also cover conference services for the translation and processing of the final report.If adopted, the resolution sponsored by the US, Sri Lanka and a few other countries, will require the Office of the High Commissioner to continue to assess progress on the implementation of OHCHR’s recommendations and other relevant processes related to reconciliation, accountability, and human rights; to present an oral update to the Human Rights Council at its thirty-second session, and a comprehensive report followed by discussion on the implementation of the present resolution at its thirty-fourth session. (Colombo Gazette) The Office of the High Commissioner for Human Rights (OHCHR) headed by Zeid Ra’ad Al Hussein would require USD 337,800 to implement the resolution on Sri Lanka if it is adopted by the UN Human Rights Council in Geneva today, the Daily Leader newspaper reported.The Office of Programme Planning, Budget and Accounts will inform the council today on the budget requirements should the resolution be passed. read more

JPMorgan profit falls 8 per cent fails key regulatory test

JPMorgan Chase said Wednesday that its first-quarter profit fell more than 8 per cent from a year earlier and the bank tried to soothe investor concerns after it failed a key regulatory test designed to prevent another financial crisis.First-quarter profit at JPMorgan, the nation’s largest bank by assets, was hurt by weak results at its investment-banking division and by loans to oil and gas companies that are now struggling to make payments because of low energy prices.As JPMorgan was announcing its quarterly results Wednesday, the Federal Deposit Insurance Corporation and the Federal Reserve announced that it, as well as four other banks, failed to meet a regulatory requirement put in place after the financial crisis. They were required to come up with a plan, known as “living will,” to unwind their operations in the event of a bankruptcy or other upheaval in a way that would avoid triggering another broad financial meltdown.Regulators called the banks’ plans “not credible” and gave them until Oct. 1 to come up with new plans or face more stringent requirements.It was symbolic defeat for JPMorgan and its executives. JPMorgan was one of the few banks to weather the housing downturn and financial crisis and CEO Jamie Dimon has repeatedly touted the firm’s “fortress” balance sheet, which he says would protect it from any future crisis.“We are going to do everything we can to fix this problem,” Dimon said in a conference call with reporters.The regulators’ issues with JPMorgan appear to be tied more into the bank’s legal structure than its balance sheet. JPMorgan’s plan relies on moving money from foreign subsidiaries, which could be difficult in event of a global financial crisis.JP Morgan Chief Financial Officer Marianne Lake told investors she did not expect that the bank’s results would be held back as it addresses regulators’ concerns. And investors did not seem to be concerned. Shares in New York-based JPMorgan & Co. rose $2.51, or 4.2 per cent, to close at $61.79 on Wednesday amid a broad rally in bank stocks.Still, this latest regulatory issue comes at a difficult time for JPMorgan and other big banks. Profits and share prices have fallen in recent months because loans to energy companies have gone bad and the Fed signalled it will slow the pace of interest rate increases, which hurts bank profits. Despite Wednesday’s rally, the financial sector is the worst performing sector of the Standard & Poor’s 500 index this year.JPMorgan said it earned $4.99 billion after payments to preferred shareholders in the first quarter. That compares to a profit of $5.45 billion a year earlier. On a per share basis, the bank earned $1.35, compared with $1.45 a year earlier.The results beat analysts’ expectations of $1.26 per share, according to FactSet. That estimate typically excludes one-time items.The bank had to set aside $719 million in the quarter to cover potential defaults of loans to oil and gas companies and materials and mining companies. JPMorgan, like most of its competition, made billions in loans to drilling companies when oil prices were near $100 a barrel. The price fell to a 12-year low to below $27 a barrel in the first quarter.Net revenue at the bank totalled $23.24 billion, compared with $24.07 billion in the same period a year earlier.The company said profit at its investment bank fell 22 per cent from the year before to $1.98 billion. Profit from its consumer bank rose 12 per cent to $2.49 billion. FILE – In this Jan. 14, 2015, file photo, people walk past a branch of Chase Bank, in New York. JPMorgan Chase & Co.

Cypress PSoC chip in special Chile mine rescue camera from Aries Industries

first_imgPSoC® helped shrink critical circuit board to enable small form-factor of Aries camera involved in the rescue of the 33 trapped in the San José mine near Copiapó, Chile. Cypress Semiconductor’s PSoC programmable system-on-chip played an important part. California-based Central California Video Engineering & Manufacturing (CCV), a subsidiary of Aries Industries, built the specialised camera that was dropped into the initial borehole to deliver the first pictures that confirmed the miners were alive. A single PSoC chip replaced an entire 51 mm wide circuit board, enabling the ultra-thin camera that was lowered 700 m below ground to the miners. The PSoC device inside the camera provides bandpass filtering and demodulation of the control signal protocol.The camera used in the rescue was the WC1750 Slimline Dual-View Waterwell Inspection Color Camera. It has a maximum outside diameter of only 44.45 mm, perfect for inspecting small boreholes. The camera has adjustable focus, electronic shutter (iris), adjustable lighting and rotation control, front view, side view selection and can withstand a depth of 1,525 m. It uses LED lighting technology that has a 10,000-hour operating life.“We were obviously thrilled to play an important role in this dramatic rescue,” said AriesCCV Vice President of Research and Development, Mike McGrew. “Our engineers work hard to develop cameras that perform at the highest level in grueling conditions. Their hard work, including using PSoC to shrink the design, paid enormous benefits in this case. We’re very proud of this accomplishment.”“It’s exciting to see that PSoC enabled the small form factor of this amazing camera, and of course to see the results of those efforts,” said Norm Taffe, Executive VP of Cypress’s Consumer and Computation Division. “The ability to integrate multiple components in a single chip is only one of many benefits of the PSoC approach. PSoC also speeds time-to-market, and lets engineers make critical changes at any time in the product life cycle. That’s why PSoC is in literally thousands of systems from white goods and cell phones, to industrial controls and medical devices.”PSoC’s unique architecture of programmable analog and digital resources integrated with a microcontroller delivers a number of important benefits to system designers, including time-to-market, the ability to react to change, reduced components due to integration, power savings, inventory reduction, and supplier consolidation. All of these benefits are important factors in PSoC’s growth story. The PSoC architecture is also at the core of other Cypress offerings, such as the TrueTouchTM touchscreen solution, CapSenseTM touch-sensing and PowerPSoCTM controllers for LED lighting.Cypress recently introduced the PSoC 3 and PSoC 5 families, which deliver unparalleled integration and flexibility across 8-, 16-, and 32-bit applications. These new products dramatically expand the served available market for PSoC products.last_img read more

Celebrate Black Friday at 30000 feet with free GoGo inflight internet

first_imgThere are simply no words to describe the raw chaotic energy of a shopping crowd at a high-traffic mall in the height of Black Friday. Keep your head down, push your way to where you need to go, and make your way to the checkout line. Or, if you are just looking for a good time, find a corner to hide in and enjoy some people-watching. Maybe you’ve decided to sit at home and smugly surf the Internet, laughing at those who didn’t get to sleep off that tryptophan overdose most of us will suffer from all that turkey.But there’s exists a group of people on this great day of capitalism that find themselves usually left out of the shopping fun. It happens when you have to spend your Black Friday traveling. Not everyone thinks about breaking out the computer on the flight back home from a holiday with family. The people at GoGo, however, have given everyone a reason.This holiday season there are more than 1,200 planes in the air that are equipped with GoGo in-flight internet. For $10, the WiFi on the flight can provide you with all the bandwidth you can use.

Airport shooting witness says laptop in backpack stopped bullet

first_imgFrappier realized the same thing he used to do business or entertain himself on a layover would also save his life. “It was in the bathroom with other people there, and it was kind of this moment where I needed other people to validate, you know, they were looking at that and going, ‘Oh, my gosh,’ you know, in order for me to believe that it was real,” he said.“Then, later, when I gave it to the FBI, they found the bullet in my backpack,” Frappier added.Frappier said, if the laptop had been at a different angle or just a couple inches over, this would have been a different outcome. “If my backpack was not on my back with the laptop in it, and if I didn’t have the type of backpack that I did, the bullet would have gone through my shoulders,” he said.Now he’s left haunted by what he witnessed inside Terminal 2. “There was one man on the ground, he got shot in the head, and his wife was right next to him, and I just — I’m gonna remember that, and I feel so horribly for them,” he said.Frappier was also left forever grateful for the unidentified man who alerted other passengers about the gunman. “I feel incredibly lucky. I feel lucky for just the circumstances, but also for that man that yelled out, ’cause he saved so many of us, and I want to thank him, whoever he was,” he said.Copyright 2019 Sunbeam Television Corp.

(WSVN) – One man said he’s lucky to be alive after he discovered his laptop inside his backpack stopped one of the Fort Lauderdale airport shooter’s bullets from hitting him, likely saving his life.In the chaos and confusion of Terminal 2 at Fort Lauderdale-Hollywood International Airport , Friday afternoon, one man had an unlikely guardian angel on his shoulder. “I was wearing a backpack on both shoulders, and when we went to the floor, I dropped and the backpack was still on my back,” said Steve Frappier.Frappier was inside the baggage claim area as bullets flew and people ducked for cover. “There was a lot of bunched up traffic by the conveyor belt, and so I moved to the distant side of it, and then I heard some firecracker sounds, like little ‘pop, pop, pop,’” he said, “and then a man yelled out, ‘This guy’s got a gun! Everyone down!’ And so we all dropped down to the ground, and that’s when the shooter started firing at people.”Steve FrappierFrappier said he was right in the line of fire. “I was turned in such a way, at one point, the shooter shot towards my direction,” he said. “There were several other people around me.”Frappier didn’t know it at the time, but he had been hit. “I felt something on my back, but there was also luggage falling on me from the conveyor belt. Where I was, there was stacked up luggage from the belt, and so when I felt something kind of near my back, I figured, ‘Well, that was just that suitcase that fell on me,’” he said.It wasn’t until he when to the bathroom that Frappier realized what had happened. “It was only several minutes later, when I went to the bathroom to check everything out, that I saw there was a bullet in my laptop and my bag,” he said.The bullet was stopped by Frappier’s Macbook Pro, which he nearly left behind on the plane. “In the rush to get off the plane, I just shoved my laptop into my backpack,” he said. last_img read more

Specs include an Intel Core i7 processor, 12GB of RAM, a 256GB solid-state drive and a 15.6-inch display. However, I strongly recommend paying an extra $50 to upgrade that display to FHD (1,920×1,080), because you’re not likely to be happy with the native 1,366×768 resolution. Spotify and most other streaming services rely on compressed audio, which robs the listener of full fidelity. Enter Tidal, the only “major” service that delivers lossless audio — meaning at least on par with CD quality, if not better. Want to see (er, hear) the difference for yourself?

Star Wars The Old Republic MMO only needs 500000 subscribers

first_imgThere’s been a lot of movement lately in the online game space switching from a subscription model to a free-to-play with virtual goods solution. While that may be the only way to make some revenue from a game for a lot of publishers, EA isn’t taking that route with the forthcoming Star Wars: The Old Republic.The Star Wars MMO will require a subscription charge, but the game doesn’t actually need that many players paying to play each month to turn a profit. According to EA’s CEO John Riccitiello, if 500,000 players sign up the game will make money.While half a million may seem like a lot, this is a game carrying the Star Wars name, and Blizzard has achieved over 11 million regular players showing what is possible. Is 500,000 really going to be that hard to achieve?While that many players would make money, EA won’t see the game as a success until it achieves one million or more with Riccitiello telling investors during a conference call:Anything north of one million subscribers is a very profitable business. Essentially it turns on a dime from being quite sharply negative in terms of its EPS impact to positive the day the product ships. As for the rumors as to how expensive the game has been to develop, he is quick to put them to rest:There’s been a fair amount of talk on various blogs, describing spends that are vastly higher than anything we’ve ever put in place. Some of them, they bring a chuckle but they also bring a frustration for those that are being responsible in the management of EA’s R&D dollars when they read sort of falsehoods out of the press.

Intel does math on oildunk test for cooler servers

first_imggigaom.com/cloud/intel-immerse … il-and-they-like-it/www.grcooling.com/ (Phys.org)—Intel just finished a yearlong test of Green Revolution Cooling’s mineral-oil server-immersion technology. Intel has tried immersing servers in the company’s oil formulation to keep the servers cool and they report good results. The Intel servers were subjected to a yearlong bath in boxes filled with the oil-based coolant. Intel’s results are one more way for the Austin, Texas-based company to pass along a convincing message that dipping a data center’s servers in oil is not crazy but a sane way to cool the data center’s power-hungry machines. The company believes its liquid cooling enclosures can cool high-density server installations at less cost. “We can reduce cooling energy use by 90 to 95 percent while also reducing server power by 10 to 20 percent,” according to the company. HP picks Intel’s Centerton for low-power server rollout Supermicro SuperServers submerged at CGGVeritas Citation: Intel does math on oil-dunk test for cooler servers (2012, September 3) retrieved 18 August 2019 from https://phys.org/news/2012-09-intel-math-oil-dunk-cooler-servers.html Explore further Patterson said that the company found the technology to be safe for its server components. At the end of the test period, the Intel servers were placed in its failure-analysis lab, which did not find any damaging effects.Green Revolution Cooling’s product is called the CarnotJet System, defined as a fluid submersion cooling solution for data center servers. It uses nonconductive liquid coolant rather than air to achieve maximum cooling efficiency and performance.Mention “oil” and add “servers immersed in oil” and for those not familiar with the results, this can sound very strange if not risky, Intel’s Patterson said. That initial reaction is worth getting past. Patterson said Intel’s research into how to build oil-optimized servers could result in a reference architecture around which server manufacturers could begin building such systems.Already, Green Revolution Cooling has a list of customer centers running computer systems that make use of the approach. These include the Oil/Gas Seismic Processing Center; European Colocation Center; East Coast Corporate Data Center; US Research Institute; and the Texas Advanced Computing Center.The coolant is clear, has a light viscosity, is odorless and is nontoxic. The company calls its coolant GreenDEF, which is a formulation of nonconductive white mineral oil. Their formulation is optimized for cooling servers and other data center hardware. center_img More information: Intel reports that the servers ran at a PUE just above 1.0, and showed no damage. Translation: Traditional air-cooled server racks often operate at a Power Usage Effectiveness rating of about 1.6. Intel’s oil-immersed servers operated at a PUE between 1.02 and 1.03, according to Mike Patterson, senior power and thermal architect at Intel.Patterson said the oil-dunking approach is now in Intel’s evaluation phase. Intel will need to understand the fuller implications of oil-optimized platforms. Potentially, the approach may reduce the cost of running data centers, as cooling through the oil immersion system can bring reductions in average and peak power consumption. Those taking their first leap to use this oil immersion approach would be those who want as much power as possible coming out of their computing operations with as little as possible applied toward cooling. When compared to present-day design principles for keeping servers cool, the oil-immersion approach could have far-reaching effects. That is what Patterson means by its having an impact on a reference architecture around which server manufacturers can build their systems. Oil immersion would do away with the need for raised floors and other requirements for air cooling. According to Green Revolution Cooling, energy is saved by removing server and power supply fans from the servers, as they are no longer necessary when servers are submerged. The company also touts the advantage of server reliability, as the servers do not collect dust. Dust is a thermal insulator that raises server temperatures and reduces reliability. One recent study, they said, showed that dust accumulation increased power draw by 2 percent due to server temperature increases. The circulation of the coolant is said to be “excellent” with uniform temperatures without hot spots. © 2012 Phys.org This document is subject to copyright.

Materials scientists devise window that mutes sound but allows air to pass

first_img Researchers discover way to allow 80 percent of sound to pass through walls More information: Air transparent soundproof window, arXiv:1307.0301 [cond-mat.mtrl-sci] arxiv.org/abs/1307.0301AbstractA soundproof window or wall which is transparent to airflow is presented. The design is based on two wave theories of diffraction and acoustic metamaterials. It consists of a three-dimensional array of strong diffraction-type resonators with many holes centered at each individual resonator. The acoustic performance levels of two soundproof windows with air holes of $20mm$ and $50mm$ diameters were measured. Sound waves of 80dB in the frequency range of $400 – 5,000Hz$ were applied to the windows. It was observed that the sound level was reduced by about $30 – 35$dB in the above frequency range with the $20mm$ window and by about $20 – 35$dB in the frequency range of $700 – 2,200Hz$ with the $50mm$ window. It is an extraordinary acoustic anti-transmission. The geometric factors which produced the effective negative modulus were obtained.Found on Arxiv Blog This document is subject to copyright.

Explore further To prevent noise from passing from one place to another, engineers generally use types of material that are able to transfer sound in the air to another medium, which then weakens its force (attenuation). For that reason, it would seem impossible to create a medium that would allow sound carrying air to pass though, while muting the very sound its carrying. But that’s what the team in Korea has accomplished.The window, is not actually a window, instead it’s two parallel planes of clear plastic separated from one another by a mere 40 millimeters—similar to double paned glass. The chamber between the plastic planes has been designed in such a way as to ensure that sound that enters is counteracted by the pressure in the chamber—using a principle known as bulk modulus (a materials’ resistance to compression.) Each chamber is “roughly” 150 millimeters square—to create a larger window the chambers were arranged in an array. The double pane approach muted sound, but not nearly as much as most would like. To cause more muting the team placed cylinders made of clear plastic through the planes (which they call emitters and receivers)—each with a piece of flat clear plastic covering both ends. A hole was then drilled through the flat plastic pieces allowing sound carrying air to pass through. As it did so, the sound was diffracted into the chamber between the two planes. The reason a cylinder was used instead of just drilling a hole in the plane was for allowing a filter to be placed to prevent the air passing through from whistling. The result is a window, or venting system, that allows for air passage while muting sound. Testing of the window showed it able to reduce sound by 20 to 30 decibels.The researchers note that changing the size of the hole allows for muting different frequencies. This they say could lead to interesting scenarios, such as a venting system that would mute annoying noises while allowing desired noise (such as waves on a beach) through along with fresh air. (Phys.org) —A team of materials scientists in South Korea has created a type of window that mutes noise while simultaneously allowing air to move through. In their paper they’ve uploaded to the preprint server arXiv, the team describes their window and how it was constructed.center_img Citation: Materials scientists devise window that mutes sound but allows air to pass through (2013, July 9) retrieved 18 August 2019 from https://phys.org/news/2013-07-materials-scientists-window-mutes-air.html Diagram and picture of the measurement of the 50mm window.Credit: arXiv:1307.0301 [cond-mat.mtrl-sci] Journal information: arXiv © 2013 Phys.orglast_img read more
