10-13-2016 • www.mnn.com If silkworms were Pac-Men, carbon nanotubes would be their power pellets. On a hunch, scientists at Tsinghua University in China fed silkworms with a solution that contained both carbon nanotubes and graphene — a super-strong material made from latticed carbon atoms — and the insect larvae immediately went to work producing a super-silk with qualities never seen before in regular silk, reports Scientific American. The super-silk was not only super-strong, capable of withstanding at least 50 percent higher stress before breaking, but it was also capable of conducting electricity. Regular silk can't do that. The discovery could lead to new ...

LOSING FACE IT WAS JUST after sundown when a man knocked on Steve Talley’s door in south Denver. The man claimed to have hit Talley’s silver Jeep Cherokee and asked him to assess the damage. So Talley, wearing boxers and a tank top, went outside to take a look. Seconds later, he was knocked to the pavement outside his house. Flash bang grenades detonated, temporarily blinding and deafening him. Three men dressed in black jackets, goggles, and helmets repeatedly hit him with batons and the butts of their guns. He remembers one of the men telling him, “So you like to fuck with my brothers in blue!” while another stood on his face and cracked two of his teeth. ...
Nano-Spike Catalysts Convert Carbon Dioxide Directly into Ethanol
Post Date: 2016-10-14 07:33:07 by Tatarewicz
0 Comments
TEHRAN (FNA)- In a new twist to waste-to-fuel technology, scientists have developed an electrochemical process that uses tiny spikes of carbon and copper to turn carbon dioxide, a greenhouse gas, into ethanol. "We discovered somewhat by accident that this material worked," said ORNL's Adam Rondinone, lead author of the team's study published in ChemistrySelect. "We were trying to study the first step of a proposed reaction when we realized that the catalyst was doing the entire reaction on its own." The team used a catalyst made of carbon, copper and nitrogen and applied voltage to trigger a complicated chemical reaction that essentially reverses the ...

"[They] show great potential for photovoltaic devices such as solar cells," said researcher Wang Zhang. Cicada wings have natural antimicrobial and anti-reflective qualities. SHANGHAI, Oct. 11 (UPI) -- A team of researchers from China's Shanghai Jiao Tong University recently developed a new class of anti-reflective materials using nanostructures derived from titanium dioxide. The scientists cited cicada wings as their inspiration. Cicada wings are marked by periodic conical structures, which researchers call "nano-nipples." Scientists were able to texture materials with tiny titanium dioxide structures that mimic the miniature dots. The added texture diminished ...

Are Humans Natural-Born Killers?
Post Date: 2016-10-11 08:40:02 by Tatarewicz

ConsortiumNews Among scientists there has been a long debate about whether human violence toward other humans is inherent, cultural or a mix of both. The question is: Are we natural-born killers, notes Lawrence Davidson. A new study, published in the journal Nature and entitled “The Phylogenetic Roots of Human Lethal Violence,” argues two points: (1) along with many other mammals and particularly primates, human lethal violence is innate because it is part of a long “evolutionary history”; and (2) for humans, however, it is also a behavior that is responsive to our cultural environment. So, over time, “culture modulates our bloodthirsty tendencies.” What ...

RI... This summer the Russian company AvtoVAZ presented its EV prototype for the Lada Vesta. This is the second electric car made by the Tolyatti-based manufacturer, located about 1,000 kilometers southeast of Moscow. ElLada was the first, appearing as a prototype in 2012, and which was based on the popular Lada Kalina. Electric cars have not been popular among Russian drivers due to a lack of infrastructure, harsh climatic conditions, high price, and limited mileage on a single charge. However, Vladimir Pirozhkov, president of the Astra Rossa Industrial Design and Innovation Center, believes Russia needs electric cars. "It's hard to breathe in Moscow, and an electric car is ...
12 Million-Year-Old Vehicle Tracks Found in Stone, Claims Geologist

Epoch Times | Petrified wheel tracks found in various locations, including parts of Turkey and Spain, were left by heavy all-terrain vehicles some 12 million to 14 million years ago, according to Dr. Alexander Koltypin, a geologist and director of the Natural Science Research Center at Moscow’s International Independent University of Ecology and Politology. This is a controversial claim, since human civilization is only thought by mainstream archaeologists to extend back several thousand years, not millions of years. That’s not to mention the idea of a prehistoric civilization advanced enough to have such vehicles. The wheel tracks cross over faults formed in the middle and late ...
First evidence emerges that women's ovaries can grow new eggs

ScienceAlert.. Women are well aware that the number of eggs they're born with is all they'll ever have, and when they inevitably run out, they can no longer have children. Hence the pressure of the biological clock. But a new study has found the first evidence that women's ovaries might actually be able to grow new eggs. If confirmed, it could mean that post-menopause women and those with fertility problems might be able to conceive naturally after all. To be clear, this is very early evidence taken from a small study involving cancer patients, and it needs to be replicated and explored further before we can say for sure what's going on. But the possibility that adult ...
Researchers turn brewery wastewater into energy storage cells

BOULDER, Colo., Oct. 7 (UPI) -- Scientists in Colorado have found a way to make brewers and battery makers allies in the quest for energy efficiency. Brewing beer is a water-intensive process. For every barrel of beer, brewers use roughly seven barrels of water. "And they can't just dump it into the sewer because it requires extra filtration," Tyler Huggins, a graduate student at the University of Colorado, explained in a news release. Treating all that water is expensive. Unless, of course, you can get someone else to pay for the treatment. In this case, that someone else is the battery industry. It turns out, brewery wastewater is an ideal place to grow the ...

RALEIGH, N.C., Oct. 7 (UPI) -- Your fruit is radioactive. In fact, most things are. Recently, scientists at North Carolina State University set out to gain a better idea of daily radiation exposure experienced by humans. The scientists are hopeful their findings will offer people some perspective and curb the levels of anxiety surrounding exposure to radiation. "We did this study because understanding how much radiation comes off of common household items helps place radiation readings in context," Robert Hayes, an associate professor of nuclear engineering at N.C. State, said in a news release. "If people understand what trace levels of radiation mean, that understanding ...

TEHRAN (FNA)- A version of Chrome due in a two months will give your PC or phone back some of that precious memory it's been gobbling up. Memory is a scarce resource in computing devices, making apps run faster and letting them do more. As websites get more complex and web browsers get more powerful, though, they gobble up more and more memory. Memory usage reductions are great. But don't expect that your hardware will be suddenly liberated. Historically, as PCs and phones steadily got more memory, programmers writing apps and websites added new features to take advantage of it. The Chrome team working on V8, the part of the browser that runs the JavaScript programs that make ...
Robotic Bees Are Now Being Built To Pollinate Crops Instead of Real Bees

BlackListedNews... Honeybees pollinate almost a third of the food we consume, but they’ve been dying at alarming rates due to threats like habitat loss and disease, as well as colony collapse disorder (CCD), the phenomenon where worker bees abandon their hives, leaving behind only the queen bee and enough food and nurse bees to help take care of the immature bees and the queen. There is also increasing evidence of a direct link between neonicotinoids, which are the most common type of insecticides, and CCD. Then, last week, federal authorities placed seven yellow-faced bee species native to Hawaii on the Endangered Species Act. And while honeybees have been dying off in many ...
Experts said Arctic sea ice would melt entirely by September 2016 - they were wrong

Dire predictions that the Arctic would be devoid of sea ice by September this year have proven to be unfounded after latest satellite images showed there is far more now than in 2012. Scientists such as Prof Peter Wadhams, of Cambridge University, and Prof Wieslaw Maslowski, of the Naval Postgraduate School in Moderey, California, have regularly forecast the loss of ice by 2016, which has been widely reported by the BBC and other media outlets. Prof Wadhams, a leading expert on Arctic sea ice loss, has recently published a book entitled A Farewell To Ice in which he repeats the assertion that the polar region would free of ice in the middle of this decade. As late as this summer, he was ...

ScienceDaily... The new research offers evidence that one's motivation is just as important for sustained attention to a task as is the ease with which the task is done. American professional golfer Tom Kite said two things about distraction that sum up the findings of a new study on the subject: First, "You can always find a distraction if you're looking for one." And, second, "Discipline and concentration are a matter of being interested." The new research offers evidence that one's motivation is just as important for sustained attention to a task as is the ease with which the task is done. It also challenges the hypothesis, proposed by some cognitive ...

Scientist Daniel Chamovitz unveils the surprising world of plants that see, feel, smell—and remember How aware are plants? This is the central question behind a fascinating new book, “What a Plant Knows,” by Daniel Chamovitz, director of the Manna Center for Plant Biosciences at Tel Aviv University. A plant, he argues, can see, smell and feel. It can mount a defense when under siege, and warn its neighbors of trouble on the way. A plant can even be said to have a memory. But does this mean that plants think — or that one can speak of a “neuroscience” of the flower? Chamovitz answered questions from Mind Matters editor Gareth Cook. 1. How did you first get ...

ScienceDaily Have you ever wondered why our hands have exactly five fingers? Dr. Marie Kmita's team certainly has. The researchers at the Institut de recherches cliniques de Montréal and Université de Montréal have uncovered a part of this mystery, and their remarkable discovery has just been published in the journal Nature. A matter of evolution We have known for several years that the limbs of vertebrates, including our arms and legs, stem from fish fins. The evolution that led to the appearance of limbs, and in particular the emergence of fingers in vertebrates, reflects a change in the body plan associated with a change of habitat, the transition from an ...
