Nanotechnology can safely help frozen organs to come back to life

Currently there is no facility available to bring frozen organs back to life. That’s why number of transplants happening are quite less than the demand. However researchers at University of Minnesota have made it possible by infusing silica coated iron oxide nanoparticles in the organs. This make possible to warm the tissue at more than 130 degree Celsius/minute that is 100 times faster than the current methods.

BHIM app is quite safe and different from other mobile wallets

The Bharat Interface for Money (BHIM) mobile app recently launched in 2016 emerged as one of the fastest growing apps in India. It has seen one crore downloads and 10 lakh transactions within 10 days of its launch. Below are key features:

  1. Easy money transfer from bank to bank and person to person (35 participating banks)
  2. Money can also be sent to non-UPI supported banks using IFSC code and account number.
  3. One can check balance and switch between accounts other than sending, receiving, and requesting money
  4. People can pay utility bills and can purchase gift cards etc.
  5. Those who don’t use data services, can use BHIM by dialing star99hash (USSD-based mobile banking service)
  6. Wallets reply on phone locking password and do not ask for password even before the transaction so if your phone is stolen you are in a trouble. On the other hand BHIM ask for password and the gateway gets blocked after three wrong tries.
  7. The amount received or sent via wallet stays in wallet and to make a transfer to bank one has to pay 1-4% processing fee. But with BHIM, one directly transfer to banks
  8. Transaction limit of BHIM is 20000/day, 10000/transaction and the limit for USSD is 5000/day
  9. It also offers various lucky draw schemes as well

Quantum computers can be a reality in 2017

Computer giants including Google and Microsoft have recently hired a host of leading lights, and have set challenging goals for 2017. Their ambition reflects a broader transition taking place at start-ups and academic research labs alike: to move from pure science towards engineering. Quantum computing has long been seen like one of those technologies that are 20 years away, and always will be. But 2017 could be the year when it can be possible.

NASA’s Cassini spacecraft just sent the first images from its new orbit around Saturn

After 20 years of traveling through space, NASA’s Cassini spacecraft is taking a close look at Saturn before plunging into the planet in September 2017. And it’s finally sending us some of its first pictures back. The final stretch of Cassini’s mission will allow us to learn more about the particles and gas molecules that linger near Saturn’s rings. Cassini began its new mission phase on November 30th, which NASA calls Ring-Grazing Orbits. Twenty of these weeklong orbits will take Cassini high above Saturn’s northern hemisphere and then past the edges of the planet’s main rings. That’s where Saturn’s small moons orbit.

NASA starts testing more fuel efficient jet engine tech

A group of engineers have developed a new jet engine tech that can improve planes’ fuel efficiency by four to eight percent, and NASA has begun testing it out. They created a new type of engine propulsor — composed of the fan and a part called the inlet, which directs air into the engine — designed to be embedded into a jet plane’s body. Jet engines are typically placed away from the aircraft’s surface, because of a highly distorted film of air called the boundary layer that envelopes the plane as it zooms through the sky. This new type of jet engine propulsor takes advantage of the boundary layer instead. More at: https://www.engadget.com

Google Earth inspired technology spies on cancer cells to learn how they evade drugs

Scientists say technology inspired by Google Earth is giving them a better understanding of how cancer cells evade the drugs meant to neutralise them. Dr Edwin Hawkins from the Walter and Eliza Hall Institute said the technology is used to watch how cancer cells and normal cells interact. “We did that by creating optical windows which we 3D-printed and manufactured, and those gave us a way of looking deep inside the tissue with existing technology,” he said. Dr Hawkins said spying on the cancer cells was essential to understanding how they behaved. More at: http://www.abc.net.au/

Microsoft to use computer science to help find cancer treatments

Microsoft has announced a range of research initiatives, including a team who are working to uncover more about the genomics of cancer — finding out which genes have gone bad in the genome. “The collaboration between biologists and computer scientists is actually key to making this work,” Microsoft’s corporate vice-president Jeannette Wing said. Using machine learning and natural language processing, Microsoft researchers will help oncologists figure out the most effective, individualized cancer treatment, by providing new ways to sort through research data. More at: http://www.abc.net.au/

Icy telescope throws cold water on sterile neutrino theory

An observatory buried deep in Antarctic ice has reported the results of its search for an hypothesized particle called the ‘sterile neutrino’: a total blank. The null result, reported on 8 August in Physical Review Letters, doesn’t spell the end of a decades-long search to find the subatomic particle, which — if found — would upend the standard picture of particle physics. But it is the strongest evidence so far that the sterile neutrino doesn’t exist at the mass range that physicists had hoped, based on anomalies from several experiments over the past three decades.  More at: http://www.nature.com/news

US government launches $400 million initiative to research 5G wireless networks

The White House has announced a $400 million research program aimed at building 5G wireless networks across the country, TechCrunch reports. The project, called the Advanced Wireless Research Initiative, will be led by the National Science Foundation (NSF). Over the next seven years, the NSF will launch and study four “city-scale testing programs” to see how 5G wireless networks could be implemented, according to a White House press release. The announcement comes just one day after the FCC voted to begin opening up high-speed airwaves to prepare the United States for 5G networks. Yesterday the FCC said it expected the first 5G networks to go live in 2020, after the airwaves have been opened and the technology is ready. More at: http://www.theverge.com/

Peeled strips of single-layer carbon could be useful in electronic circuitry and pave way for new discoveries in technology.

Graphene, a single-atom-thick sheet of carbon, is stronger than steel and as stiff as diamond. Yet, this tough, thin material can also be induced to peel itself to pieces. Puncturing a hole in graphene with a diamond tip and repeatedly moving that tip back and forth — rather like rucking up a carpet — causes narrow strips of carbon to curl spontaneously upwards, tearing out of the graphene layer and even folding back on themselves, scientists from Trinity College Dublin report in an article in Nature. The discovery is “entirely surprising”, says James Tour, a specialist in nanotechnology at Rice University in Houston, Texas. Tour says that since the technique is in its infancy and the researchers haven’t yet demonstrated they can control it, it’s hard to see exactly how it could be used. But the discoverers of the effect, physicists Graham Cross and James Annett, think that it should be possible to control the size of the ribbons and the way that they peel and fold, potentially making them useful in electronic circuitry.

Mobile-phone expansion could disrupt key weather satellites. The US government is considering a plan to allow wireless firms to share radio frequencies used in weather forecasts.

As Hurricane Patricia barrelled down on Mexico last October, forecasters at the US National Oceanic and Atmospheric Administration (NOAA) grabbed as many ­satellite images as they could to track its progress. But at least one crucial shot failed to download. A 22 October image from the ­Geostationary Operational Environ­mental Satellite (GOES) system showed a black swathe — no data — across most of the Pacific Ocean. The culprit was radio interference from mobile-phone companies. And the problem may soon get worse. The US Federal Communications Commission (FCC) is considering whether to allow a commercial mobile-phone company to share a crucial, additional set of frequencies that NOAA uses for time-critical weather transmissions. More at: http://www.nature.com/news

Mobile Ransomware Attacks Have ‘Skyrocketed’ in the last year

As per the security group Kaspersky Lab’s latest report, the hackers are increasingly targeting mobile users and the number of mobile users affected by ransomware “skyrocketed” during January-March 2016. Kaspersky said that between April 2015 and March this year, 136,532 of its users encountered a mobile version of ransomware. In the previous time period, the number of impacted users was 35,413. The report says that out of the overall mobile users that are affected by ransomwares, around 23 percent are from Germany. After the Germany, the impacted users in Canada, UK and the US are impacted the most at 19.6 percent, 16.1 percent and 15.6 percent respectively. “Ransomware is a type of malware that, upon infecting a device, blocks access to it or to some or all of the information stored on it. In order to unlock either the device or the data, the user is required to pay a ransom, usually in Bitcoins or another widely used e-currency,” Kaspersky explained in its report on Wednesday.
