Researchers have found a way to use diamonds to convert nuclear waste into long-lasting batteries. A team of physicists and chemists at the University of Bristol discovered the new technology, which transforms thousands of tons of troublesome nuclear waste into lab-grown diamond batteries capable of generating a small amount of electricity. The diamond batteries, like the precious gems they are based on, could last essentially forever.
Liquid lithium-ion batteries are the most common kind of rechargeable batteries used in our electronic devices as they offer a high energy density, stable energy capacity, and low self-discharge for little cost. However, they’re also extremely flammable as we witnessed from the recent Samsung Galaxy Note 7 explosions.
The new research name change the way scientists study lung disease idiopathic pulmonary Fibrosis particularly. Earlier doctors used to grow two dimensional cultures that could not be used to demo certain diseases such as lung scarring. Even when such cells come from patients they turn out to be healthy on flat culture. To address this problem scientist at University of California Los Angeles group three-dimensional organoids that resonate with sections of human lungs instead of just cells.
A group of Cambridge scientists are attempting to grow human brains outside of the body in a lab. But they don’t look anything like what you might imagine. The “cerebral organoids” are made with stem cells derived from human skin and raised in giant incubators. Without any kind of blood supply, they receive nutrients by soaking in a special fluid. And these brains are tiny, small enough to fit in a petri dish – about four millimeters across and crammed with about two million neurons. For the sake of comparison, a fully developed mouse brain contains four million neurons. The average adult human brain, up to 1,000 trillion.
This year’s Nobel Prize in Chemistry has been awarded to three scientists who figured out how to build tiny machines out of molecules. The machines, which include a nano-sized car, are invisible to the human eye and have important implications in medicine and other fields. The researchers — Jean-Pierre Sauvage, J. Fraser Stoddart, and Bernard Feringa — will share the prize equally.
NASA hopes to send a manned mission to Mars within the next two decades. To successfully establish a colony, the first Martians will need to be able to build structures from materials that are resilient and – ideally – sourced locally. Dr. Lin Wan and colleagues at Northwestern University have devised a method for creating concrete on Mars that meets these standards. The team’s breakthrough is made possible through the use of sulfur, an element whose “rotten egg” smell should be familiar to any Earthling.
This is the most common complaint among all smartphone users- the battery just sucks! Yes.... in today’s world where a person uses his smartphone for almost everything- right from shopping to bill payments, bank withdrawals and deposits. Add to this the many hours spent on social networking sites and checking and replying to official and personal mails- the battery of the phone seldom lasts for more than half of the day.
Wood-colored may soon lose its meaning if scientists from the University of Maryland, College Park, manage to apply a new technique to the key byproduct of the trees of our world. In a nifty new process, a group of researchers have managed to strip away wood’s distinctive, well, wooden colors, and instead made it transparent. It takes just two steps (complicated as they may be) to turn a block of wood into what looks a lot like a block of plastic, and scientists are pretty thrilled about the implications of this new procedure.
A team working for Russian President Vladmir Putin shocks the world by claiming teleportation technology could be operational by 2035. The Kremlin plans setting aside £1.1billion to fund an inter-agency group called the "National Technology Initiative" (NTI), which will work using a technique called quantum communications infrastructure.
You may have heard of neutrinos: the tiny subatomic space particles found throughout our galaxy, which pass through our bodies in their tens of thousands every single second. Formed in the first seconds of the universe, before even atoms, they are also continually created by nuclear reactions, such as those which take place in the sun.
