Penn Engineers have unveiled a groundbreaking chip that harnesses the power of light waves, revolutionizing the way complex mathematical operations essential for AI training are performed. This innovative chip promises to dramatically boost the processing speed of computers while significantly slashing their energy consumption. The silicon-photonic (SiPh) chip marks a milestone by integrating the pioneering research of Benjamin Franklin Medal Laureate and H. Nedwill Ramsey Professor Nader Engheta, who has mastered the manipulation of materials at the nanoscale to execute mathematical computations using light — the fastest mode of communication. This breakthrough combines Engheta’s expertise with the SiPh platform, leveraging silicon, a readily available and cost-effective element widely used in mass-producing computer chips.

Scientists have developed a beating heart of a mouse from stem cells — a development first of its kind and the most sophisticated till date. The in vitro (in a dish) model [VIDEO HERE] is that of a tiny mouse embryo with a beating heart and its muscles, blood vessels, gut and nervous system beginning to develop.This new model, developed at the University of Virginia School of Medicine by Christine and Bernard Thisse, is a major step forward in scientists' efforts to mimic the natural development of a mammal by using stem cells. Its existence is a wonder that will help scientists understand mammalian development, battle diseases, create new drugs and, eventually, grow tissues and organs for people in need of transplants. The study has been published in Nature Communications.

A new study by scientists at University of Edinburgh has shed light on the links between vitamin D deficiency and its influence on susceptibility to diseases such as multiple sclerosis. For the study, researchers focused on how vitamin D affects a mechanism in the body’s immune system – dendritic cells’ ability to activate T cells. It has long been known that inhealthy people, T cells play a crucial role in helping to fight infections. In people with autoimmune diseases, however, they can start to attack the body’s own tissues. By studying cells from mice and people, the researchers found vitamin D caused dendritic cells to produce more of a molecule called CD31 on their surface and that this hindered the activation of T cells. The team observed how CD31 prevented the two cell types from making a stable contact – an essential part of the activation process – and the resulting immune reaction was far reduced. Study is published in Frontiers of Immunology.

There is a possibility that super-Earth planet orbiting the Barnard b (or GJ 699 b) star could potentially be having atmosphere and possibly life, scientists have said. The planet is likely cold (-170 degrees centigrade), but scientists believe that it could still have the potential to harbor primitive life if it has a large, hot iron/nickel core and enhanced geothermal activity. Scientists have published their findings in a paper titled, “X-Ray, UV, Optical Irradiances and Age of Barnard’s Star’s New Super Earth Planet — ‘Can Life Find a Way’ on Such a Cold Planet?” [PDF].

Taking his bet to rather extreme,John McAfee has said that if bitcoin prices do not surge to$500K per coin in three years, he will eat his dick on national television. This comes in follow up to a tweet he sent out yesterday wherein he said that according to his doctorate in point-set-topology,bitcoin will hit $2,431,013 in 3 years while other other math systems i.e. cryptocurrencies will be trading at anywhere between $1,900,000 and $2,600,00[0]. To this a Twitter user asked if McAfee was willing to place a bet on"1btc 500k $ within 3years?" to which he replied through a rather extreme wager: "if not, I will eat my dick on national television."

Wireless charging of moving objects is still a thing in distant future, but a recent study by researchers at Stanford wherein they wirelessly transmitted electricity to a nearby moving object is a firm step in that direction. The experiment demonstrated only involved a 1-milliwatt charge, but in real-life scenarios, moving objects will most probably be electric cars that would require tens of kilowatts to operate. Stanford scientists have said they are now working on greatly increasing the amount of electricity that can be transferred, and tweaking the system to extend the transfer distance and improve efficiency.

A study has shown that use of drones as first responders to out-of-hospital cardiac arrest (OHCA) could reduce response time by over 16 minutes — the time that could critical for survival of the patient. In the study published in JAMA, researchers simulated out-of-hospital cardiac arrests and dispatched drones carrying an automated external defibrillator to the location where the cardiac arrests were simulated. Researchers found that these drones arrived in less time than emergency medical services, with a reduction in response time of about 16 minutes.

Strong tail muscles are the reason why proto-dinosaur ancestors became bipedal and this bipedalism was inherited by dinosaurs over the course of millions of years, says a new study by scientists in Canada. University of Alberta scientists have revealed through their study [PDF] published in Journal of Theoretical Biology that dinosaurs didn’t just start walking on their two back feet overnight, but it was strong tails of their proto-dinosaur ancestors that played a huge role in enabling the dinosaurs stand on their two feet and move about. This is by far one of the most plausible explanations behind the bipedalism of dinosaurs.

Scientists in the UK have developed a HIV test on a USB stick that uses just a drop of blood to detect whether the subject is HIV positive or not in less than 30 minutes. The disposable test will revolutionise the way in which HIV tests are conducted around the world specifically in remote areas where availability of equipment for lab based tests is sparse. Scientists behind the study published in journal Scientific Reports are optimistic that their technology could allow patients to regularly monitor their virus levels in much the same way that people with diabetes check their blood sugar levels.

US space agency NASA has developed a new electroactive material that when applied on wounds can speed up the healing process as well as keep infections at bay. NASA says that its new material that can be given the shape of a bandage has ample of applications including on battlefields for the wounded military personnel, patients who have undergone surgery, patients who may have suffered from serious wounds and injured astronauts in space. The bandage made out of the electroactive material [PDF] has to be applied on an exterior wound. Using low level electrical stimulation generated within the material itself, the bandage promotes as well as speeds up the wound healing process and protects it from infection.

A new study by researchers at Princeton University has revealed that levels of atmospheric oxygen have been declining over the last 800,000 years. While the decline isn't substantial at somewhere around 0.7 per cent relative to current atmospheric-oxygen concentrations in the stipulated time, the decline has accelerated over the last century with increased use of fossil fuels around the world. Researchers compiled 30 years of data to construct the first ice core-based record of atmospheric oxygen concentrations for nearly a million years. To come up with historic levels of oxygen, researchers used measured ratios of oxygen-to-nitrogen found in air trapped in Antarctic ice.

Science has proved that Popeye was indeed correct in his proposition that spinach gives energy as a new study has shown that spinach-based extract can generate electricity from sunlight. Scientists at Technion-Israel Institute of Technology used simple membrane extract from spinach leaves to develop a bio-photo-electro-chemical (BPEC) cell. This BPEC cell takes in sunlight and water and sunlight as its inputs and produces electric current, hydrogen and oxygen. Researchers are hopeful that further research in this direction will one day help develop new technologies for the creation of clean fuels from renewable sources such as water and solar energy.
