    A new device allows for collection of blood without using needles - science news

    A device that allows collecting of blood without the use of needles is being developed by a startup from EPFL, Switzerland. The device will allow people to collect blood samples at home, without pain. The company did not reveal information about how the device works, but it is known it allows drawing enough blood for most tests in a similar amount of time as conventional methods. The blood samples still need to be sent to a specialized laboratory for testing. Interestingly, the system is connected to the internet to ensure that each blood sample is traceable from the moment of the sample collection until the results are released.

    Photons interact to form new photonic matter. Physics short science news

    When two beams of light intersect, the photons from the two sources ignore each other and pass by without any interaction occurring. However, under special conditions the photons could be forced to interact. This is exactly what a new study reports: photons from two light sources were made to interact and this event resulted in the formation of a new kind of photonic matter. The physicists observed groups of three photons interacting when a weak laser was shone through a dense concentration of ultracold rubidium atoms. Besides the fundamental scientific importance of the discovery, there are also practical applications such as the field of quantum computers.

    New chip reduces neural networks’ power consumption by up to 95 percent - short science news

    Neural networks are at the basis of many artificial-intelligence applications. However, this comes at a cost, since neural networks require a high amount of energy which makes them unsuitable for small, portable devices. Now, MIT researchers have developed a special-purpose chip that increases the speed of neural-network computations by three to seven times over its predecessors, while reducing power consumption 94 to 95 percent. This opens the possibility of running neural networks on smartphones and other small devices.

    Lets put your genetic code on the blockchain and share it

    Traditionally, when you do a DNA test, the company which does it owns the genetic data. However, Nebula Genomics has proposed to sequence the genome for $1000, give insights on it and then secure it on the blockchain. Pharma companies need large genetic databases to develop new drugs. This sets the way for individuals to sell their genomic data directly to these companies thereby foregoing middlemen. With the plans going underway soon, the implications are limitless.

    Volcanic ash reduces the energy required to manufacture concrete

    Scientists have discovered that adding volcanic rock dust to concrete may be an effective additive, leading to a decrease in energy consumption. According to the study, it takes 16 percent less energy to construct 26 concrete buildings made with 50 percent volcanic ash, compared to traditional concrete. This makes possible the construction of sustainable cities with low environmental impact. Currently the manufacturing of traditional Portland cement is responsible for about 5 percent of the world’s carbon dioxide emissions. This raises the possibility that the cities of the future will be made of volcanic ash to reduce the environmental footprint.

    New technique allows repeated change of color for 3D printed objects

    The present 3-D printing technology does not allow the modification of a printed object once it is finished. Researchers from MIT now present a revolutionary technique that allows repeatedly changing the color of a 3-D printed object, after fabrication. They used a proprietary ink which changes color when exposed to ultraviolet light. This allows the change in color to occur in about 20 minutes. Currently the method is optimized for plastic objects but the team is working on expanding this to other types of materials such as clothing.

    Most secure marking system for fighting counterfeit goods developed

    Fake products are a huge economical burden worldwide. Sometimes they can even put the life of people in danger, as in the case of counterfeit drugs. There are continuous efforts to improve detection of fake products. Finally, a team of researchers from Copenhagen created the best marking system to combat counterfeit goods. The system works by assigning a unique digital fingerprint based on lanthanide luminescence to an original product. The assignment of the ID is random, thus it is basically impossible to hack. The system is fully functional and researchers estimate it can be on the market in one year.

    New artificial synapse works faster than synapses in the brain

    Researchers at the National Institute of Standards and Technology (NIST, USA) have developed a superconducting switch that works like a natural synapse in the brain , but a lot faster. It is designed to connect processors (like connecting brain cells) and to store memory (synaptic plasticity) in future computers that operate like the human brain. Like a synapse, the switch integrates multiple bits of information in stead of only 1 or 0 bits, processes this, and fires a burst of electricity depending on the outcome of information processing. Technical hurdles need to be taken, however, before the switch can be used for real computing.

    Technology news: New technology allows making fuel cells 100 times cheaper

    Fuel cells, similar to batteries, could power many things, from computers to cars. The problem is that producing them can be quite expensive because they contain platinum, a very expensive metal. In a paper published recently, a group of scientist from California describes a new method to build fuel cells. This technique replaces platinum with cobalt and porous carbon nanofibers, an innovation that decreases the costs by a factor of 100. The many potential applications of fuel cells are now much closer due to this cheaper way of fabrication.

    Could Artificial intelligence strike a bargain better than humans?

    Artificial intelligence has made major advances and is now able to beat humans in Chess and also at Go. However, could we teach AI to also co-operate and compromise? Researchers at Brigham Young University have developed an algorithm to do just that. Using an algorithm S# they programmed machines for a two-player game to see how they would cooperate with humans. The machines were programmed to use common phrases like, 'Sweet. We are getting rich', or 'In your face!' and the human counterparts in the game at times couldn't distinguish between a machine and a human. The use of cheap talk by the machines surprisingly increased the level of cooperation. This shows that using simple algorithms machines can be trained to cooperate with humans which might be at times better than humans themselves.

    A greedy cryptocurrency miner might be a bigger threat than spyware or viruses

    Coinhive, the software that uses the computational processing power of other people's devices to mine cryptocurrency is becoming the most prevalent form of malware on the internet. This practice of secretly mining cryptocurrency on others' hardware has affected 55% of all organizations globally and has overtaken ransomware as a tool of choice to extort money. Further, researchers at the security firm Wandera have claimed that such exploitation on mobile devices has increased by 250%. Also, such attacks are becoming more sophisticated since some of these could be detected only by Darktrace, a program which uses artificial intelligence to identify cyber threats and went unnoticed by the usual detection tools.

    Bitcoin and Ethereum might not be as decentralized as you think

    Bitcoin has been the darling of the previous year showing a meteoric rise in its 'virtual' value. The dreamy view of Bitcoin and for that matter, Ethereum is based on the idea that they are decentralized giving power back to the people. However, cryptocurrency expert Emin Sirer and colleagues from Cornell University says that no one has even bothered to fact check as to how truly decentralized these systems are. They found that 4 Bitcoin mining operations accounted for 53% of its mining capacity while 3 miners accounted for 61% of Ethereum's mining. The beg the question to be asked: 'Are these cryptocurrencies truly decentralized?'

    China looking to built yet another giant telescope to detect aliens

    China plans to build the world’s largest steerable telescope in a quest to detect dark matter, gravitational waves and possible alien signals. China already has the world’s largest telescope, the Five hundred meter Aperture Spherical Telescope (FAST). The new telescope will be located in the Xinjiang Autonomous Region and will be named as the Qitai 110m Radio Telescope (QTT). FAST covers lower frequencies as proposed for QTT, however both the telescopes will have an overlapping coverage of 150 MHz to 3GHz. This would mean that signals detected by one telescope could be confirmed by the other provided data is being analysed in real time.
