HYDERABAD, India, Oct. 7 (UPI) -- Carbon is a common ingredient in the production of smaller lithium batteries, but it doesn't work as well in larger batteries, like those used to power electric cars. That could soon change. Researchers in India have discovered a unique material for carbon-based anodes, the parts of a lithium battery that store energy and facilitate the flow of electricity. The material is candle soot, the unique carbon nanoparticles wafting off the end of a candle flame. Carbon used in smaller batteries loses its conductivity when scaled up, but candle soot features the proper density for use in larger batteries. As the scientists experiments proved, the shape and ...

ScienceAlert...Right now, odds are that one in every four diamonds on sale around the world is a blood diamond - mined in a war zone and sold to finance armed conflict and civil war. And for those wanting to steer clear of such a commodity, it’s becoming nearly impossible to figure out the difference between a clean and a dirty diamond. Which is why the market for lab-made diamonds is slowly but surely growing, offering a cheaper, more environmentally friendly, and ethically sound option that looks just as pretty as its natural counterpart. "To a modern young consumer, if they get a diamond from above the ground or in the ground, do they really care?" Chaim Even-Zohar from ...

Sputnik... An urgent warning has been lodged with the United Nations that delays over negotiations pertaining to autonomous lethal weapons of the future could spell failure in the fight to stop deadly robot wars from becoming a reality. The fight for a preemptive ban on killer robots is intensifying at the UN General Assembly meeting in New York, but the deal may not happen in time from such Terminator-type robots from being deployed, the Guardian reported. The robotics industry worldwide is now worth an incredible $30 billion, and is growing exponentially. This represents a challenge for scientists to reign in the manufacture of the technology before it is uncontrollable — and ...

ScienceAlert... Canada’s Arthur B McDonald and Japan’s Takaaki Kajita have won this year’s Nobel Prize in Physics for their surprising discovery that tiny, subatomic particles called neutrinos have mass. Their experimental results forced scientists to rethink the Standard Model of particle physics that had successfully explained all observations of the subatomic world for decades. What are neutrinos? Neutrinos are produced when radioactive isotopes decay and have been shrouded in mystery ever since Wolfgang Pauli first proposed them in 1930. In the Standard Model, they were assumed to have no mass (like particles of light, photons) and be neutral (lacking electric charge). ...

BELFAST, Northern Ireland, Oct. 5 (UPI) -- A variety of research suggests migrating birds use electromagnetic maps to guide their paths north and south. But it is a difficult hypothesis to prove. To show that electromagnetic navigation is more important than visual cues, researchers decided to manipulate the earth's electromagnetic fields along the migration route of Eurasian reed warblers traveling along the Russian coast. Previously, the same team of researchers -- from the Queen's University Belfast, in Northern Ireland -- captured a flock of a warblers near the Biological Station Rybachy, along the Russian coast, and released the birds 1,000 miles east in Kishkinev, Russia. ...

ScienceAlert... Researchers in the US have created a new type of lithium-ion battery that uses portabella mushrooms - yes, you read that right - instead of the graphite that currently forms the batteries inside our mobile phones. And while it sounds like the type of idea you might hear at a high school science fair, evidence suggests that these new batteries might actually last longer than traditional batteries, and could give our phones better battery life as they age. And that's not all - the mushroom batteries are also incredibly cheap, easy to make, and, best of all, they're pretty much biodegradable. Which will make a big difference to the environment as our demand for ...

RALEIGH, N.C., Sept. 30 (UPI) -- New research suggests fingerprints can reveal a person's ancestral background. Researchers at North Carolina State University say their proof-of-concept study, published this week in the American Journal of Physical Anthropology, holds promise for both forensic scientists and anthropologists looking to fingerprints for info about the near and distant past. Typically, when anthropologists study fingerprints, they look for Level 1 details like pattern types and ridge counts. Forensic scientists are interested in more specific Level 2 details, like where a ridge splits in two. Study author Ann Ross looked at both. "This is the first study to look ...
World's first optical ‘rectenna' converts light directly into a DC current

ScienceAlert... Scientists in the US have assembled the first ever optical rectenna - a device that’s part antenna, part rectifier diode, and uses the functions of both to convert light into a direct electrical current. The device uses an array of carbon nanotubes that function like tiny antennas to capture light, and from this it generates an oscillating charge that travels through the rectifier, which then switches on and converts the alternating current (AC) into a direct current (DC). It’s taken scientists more than 40 years to get light working in this way, and the invention could lead to new technologies for converting heat waste into electricity and more efficiently ...

ScienceAlert... The Swedish government announced this week that they will be spending an extra US$546 million on renewable energy and climate change action in their 2016 budget, with the aim of becoming one of the world's first nations to end its dependence on fossil fuels. They haven't set a deadline for this ambitious goal just yet, but last year the country announced plans to make its capital Stockholm fossil fuel-free by 2050, so we're imagining a similar time frame. It may seem like a pretty big task, but the Scandinavian country already gets two-thirds of its electricity from non-fossil fuel energy sources - predominately hydroelectric and nuclear - and it will now be ...

Global warming: are trees going on strike

Yahoo... Paris (AFP) - Trees, crucial absorbers of climate-harming carbon dioxide gas, may finally be balking at an ever-earlier spring season brought on by global warming, researchers said Wednesday. Over the past several decades, trees across central Europe have been steadily sprouting their spring leaves earlier in response to warmer temperatures, they said. As a result, forests absorbed more carbon dioxide in a longer growing season -- a boon that has been worked into global warming projections. But a study published in the science journal Nature said trees have slowed their pace of seasonal advance -- raising fears it may stop altogether. The slowdown "suggests a current and ...

ScienceAlert... Scientists in the US have linked up the brains of participants almost 1.5 km apart, allowing them to play a 20 questions-style game using nothing but their thoughts. This is the first experiment to demonstrate that two brains can be linked up directly to allow one person to accurately guess what's on the other's mind, and it's a pretty huge deal. The experiment involved a question-and-answer game, but instead of asking each other questions in person, the participants were put in separate buildings and were not allowed to talk to each other or communicate using anything but thoughts transmitted over the Internet. Using this system, participants were able to ...
