RT... A flaw in the Linux operating system lets hackers inject malware into downloads and expose the identities of people using anonymizing software such as Tor – even for those who aren’t using Linux directly. In a Wednesday presentation at the USENIX Security Symposium in Austin, Texas, researchers with the University of California, Riverside showed that the flaw lies in the Transmission Control Protocol (TCP) used by Linux since late 2012.

How To Charge Electric Cars Fast Like Gas Pump.

PMF... I was considering the charging of electric cars. To be useful, they must be rechargeable quickly, this two hours and eight hours is simply unacceptable. Solution is to have supercaps charge in parallel, and discharge in series. A multitude of small supercaps connected through a network that switches from serial to parallel. Serial for driving and power delivery, parallel for charging. Being small caps, they would all charge instantly through the parallel network, then switch to serial/parallel to deliver power. I think this way, you can stop at a charge station and recharge your Tesla for another 300km in about thirty seconds. Same as with gasoline. And caps are very light. ...
What can killer whales teach us about the menopause?

The menopause is a puzzle for biologists. Why would the female of a species cease to reproduce half way through her life, when natural selection favours characteristics that help an individual's genes survive? A study of killer whales - one of only two mammals apart from humans to undergo the menopause - is providing clues. Granny is very spritely for a centenarian. When I finally catch sight of San Juan Island's local celebrity, she leaps clear out of the ocean to delighted gasps from everyone on my boat. Granny is a killer whale, or orca. She lives in a coastal area of the North Pacific, close to Vancouver and Seattle, known as the Salish Sea. And while she is affectionately ...

Tiny homes have become a social movement we can’t ignore. People all over the world are choosing to downsize the space they live in for a happier life. In the U.S., for instance, the typical American home is around 2,600 square feet, but the typical tiny home is only between 100 and 400 square feet. They come in all shapes, sizes, and forms, but they all have one thing in common: they allow simpler living in a smaller, more efficient environment. People have joined this movement for many reasons, whether it be concerns over the environment or their own finances or the desire for more time and freedom. Most Americans spend one-third to one-half of their entire income on their homes, ...
US presidential candidate Jill Stein thinks wi-fi is a threat to children’s health

The US Green Party just officially nominated Jill Stein as its presidential candidate, and to mark the occasion, the internet dug up a YouTube video from earlier this year that has her casting some serious shade on basic technology when it comes to kids. In the video below, Stein not only denounces the move towards giving every child access to a computer at school, but also says, "We should not be subjecting kids' brains" to wi-fi. Wait, what? As a Harvard-educated physician, Stein should know better than to freak people out with conspiracy theories that have no basis in science, especially when it comes to their kids. As we discussed last year when a French woman made ...

RT... French lawmakers have given the go-ahead for driverless cars to hit the highway on a trial basis, as part of the government's "New industrial France" plan to make some 34 areas of the economy more competitive on the world stage. The approval to allow the use of “autonomous vehicles” on the roads came after the Council of Ministers ratified an amendment to the Vienna convention. From 1968, the UN Vienna Convention on Road Traffic formed the basis of national road regulations in over seventy countries that ratified the treaty. One of the stipulations was that the driver must control his vehicle at all times. Read more Tesla Motors Inc Chief Executive Musk poses ...

A pill to help insomniacs drop off instantly could be developed after scientists discovered the brain switch which triggers sleep. Dubbed ‘Sandman’ the switch is triggered by falling levels of the chemical dopamine which is known to keep people awake. Scientists at Oxford University have been trying to work out how the brain suddenly switches off in sleep, a process which has widespread effects throughout the brain. The breakthrough could lead to a new generation of sleeping pills Sleep is governed by two systems—the circadian clock which monitors the time of day, and a mechanism called the ‘sleep homeostat’ which can trigger sleepiness even when it is not dark. ...
Desert elephants pass on knowledge -- not mutations -- to survive

Despite reported differences in appearance and behavior, DNA evidence finds that Namibian desert elephants share the same DNA as African savanna elephants. However, Namibian desert-dwelling elephants should be protected so they can continue to pass on their unique knowledge and survival skills to future generations. "The ability of species such as elephants to learn and change their behavior means that genetic changes are not critical for them to adapt to a new environment," said lead author Alfred Roca, a professor of animal sciences and member of the Carl R. Woese Institute for Genomic Biology at the University of Illinois. "The behavioral changes can allow species to ...

pioneer weather wisdomThis year when I was getting ready to plant my spring garden, I was a little hesitant to plant according to frost date this year. In February, I had seen a local farmer post on Facebook something that sounded to me like pioneer weather wisdom: February thunder brings a May frost. It sounded like something out of the Farmer’s Alamanc. We had a thunderstorm on February 2, this year, and while our last frost date is usually around Mother’s Day (May 8), we had a frost on May 16. That frost damaged several crops in the area, and I was glad I had seen that farmer’s post and had waited to plant in my garden. I saw another saying come true this year as well ...
Flossing might not actually have any proven medical benefits

ScienceAlert: It seems like simple, obvious advice: Eat your vegetables, get some exercise, and - of course - floss. Or not. Turns out that despite being recommended by numerous scientists and universities, the effectiveness of flossing has never been researched, according to a new report from the Associated Press. The US government has recommended flossing for nearly four decades. But according to the Dietary Guidelines for Americans, a set of recommendations the agency sends out every five years, all of the recommendations have to be grounded in scientific evidence. And flossing is, well, not. In its report, published Tuesday, the Associated Press says that it used the Freedom of ...

TreeHugger The Lorax might have spoken for the trees, but it turns out that trees can speak for themselves. At least to other trees, that is. While it's not news that a variety of communication happens between non-human elements of the natural world, the idea of mycelia (the main body of fungi, as opposed to the more well-known fruiting bodies - mushrooms) acting as a sort of old-school planetary internet is still a fairly recent one, and may serve as a spore of a new breed of forestry, ecology, land management. Paul Stamets famously posited that "mycelia are Earth's natural Internet," and a variety of research has borne out that concept, but like many things we ...

WAPO... CANTERBURY, England — Britain has been a powerhouse of discovery since the age of science began. Newton, Darwin, Crick? They parted the curtain on gravity, evolution and DNA. Now comes Brexit, and to use a nonscientific term, the scientists in the country are freaking out. Since the vote in June to leave the European Union, leaders of Britain’s scientific academies are making dire predictions about what could happen to research and innovation here. Damage to British research, the scientists warn, could be among the cascade of unintended — and largely unappreciated — consequences of the vote to exit the bloc. The researchers worry that Britain will not ...

The Ukrainian government has announced a plan to turn the area surrounding Chernobyl - the site of one of the worst nuclear meltdowns in history - into a solar energy farm, by constructing a series of solar panels inside the exclusion zone. Not only would this plan - which is currently seeking investment - allow the country to use a giant chunk of radioactive land that’s unfit for human settlement, it would also provide a cheaper source of reusable energy that might decrease the country’s reliance on Russia. "The Chernobyl site has really good potential for renewable energy," Ukraine’s environment minister Ostap Semerak said in an interview in ...

Scientists are baffled at this seemingly altruistic behavior, which seems to be a concerted global effort to foil killer whale hunts. humpback whale Humpback whale to the rescue? (Photo: Wiki Commons) Humans might not be the only creatures that care about the welfare of other animals. Scientists are beginning to recognize a pattern in humpback whale behavior around the world, a seemingly intentional effort to rescue animals that are being hunted by killer whales. Marine ecologist Robert Pitman observed a particularly dramatic example of this behavior back in 2009, while observing a pod of killer whales hunting a Weddell seal trapped on an ice floe off Antarctica. The orcas were able to ...

ScienceAlert... Back in 2014, doctors in China were shocked when they discovered that a 24-year-old woman was living without her cerebellum, a vital section of the brain that holds up to 50 percent of a person’s total neurons. Even crazier, the woman – who remains unnamed – had no idea of her condition and had been living out a pretty normal, full life, proving just how little we know about the brain and how it can adapt to cope with what should be a debilitating condition. The woman’s story started in 2014, when her mother brought her into a Chinese hospital in Shandong Province because she was complaining of nausea and dizziness. Since these are not uncommon issues, ...
To keep soil health, scientists say mix up plant species

MANCHESTER, England, July 28 (UPI) -- Soil health is deteriorating around the globe. A combination of commercial agricultural practices, global warming and pollution are draining nutrients and encouraging the accumulation of contaminants. The solution, scientists say, is biodiversity. New research highlights the importance of soil structure for soil health. Advertisement As a new paper in the journal Ecology Letters explains, the best way to maintain proper soil structure is to increase the diversity of plant species. Soil relies on plant roots for water and protection from erosion. While the roots of some species are especially good at keeping soil well-watered, the roots of other ...

Researchers at Ohio State are trying to turn the lowly dandelion into a sustainable source of rubber. COLUMBUS, Ohio, July 27 (UPI) -- Scientists have developed a dandelion strain with natural rubber in its roots. The summer weed that invades suburban lawns could be the next rubber tree. Researchers are working to improve the weed so that it can be produced fast and efficiently enough to be a sustainable source of rubber. Only 10 to 15 percent of the dandelion's roots are rubber, making the crop much less efficient than the rubber trees grown on Southeast Asian plantations. But the rubber trees of Thailand, Indonesia and Malaysia take years to mature, making it difficult for farmers ...

Graph of average yearly sunspot numbers showing the 11-year solar cycle. Encyclopædia Britannica, Inc. Sunspot activity waxes and wanes with roughly an 11-year cycle. In 1894 the English astronomer Edward Walter Maunder pointed out that very few sunspots had been observed between 1645 and 1715. Astronomers such as John Flamsteed and Gian Domenico Cassini who did observe sunspots during that period noted that they were the first they had seen in years. However, most of Maunder’s fellow ...
