Forget Passwords How Playing Games Can Make Computers More Secure

It seems like something out of a Robert Ludlum spy novel. Someone tries to coerce you into revealing your computer security passwords. You might be tempted to give in, but it is impossible for you to reveal your authentication credentials. You do not actually know them because they are safely buried deep within your subconscious. Sounds a bit extreme just to make sure no one can log on to your laptop or smartphone, but a team of researchers from Stanford and Northwestern universities as well as SRI International is nonetheless experimenting at the computer-, cognitive- and neuroscience intersection to combat identity theft and shore up cyber security—by taking advantage of the human brain’s innate abilities to learn and recognize patterns....

France Plans To Reduce Nuclear In Favor Of Renewables

France, one of the world’s leaders in nuclear energy production, plans to draw down nuclear’s share of electricity generation from 75 to 50 percent by 2025—giving itself a 10-year time frame equivalent to the complete shutdown now ongoing in Germany. Which reactors are to be disconnected is not specifically mentioned. “Finally!” gasped French headlines last week. After months of national debate—of amended drafting bills and a one-year parliamentary discussion interspersed with joint committee reports and opposition intransigence—the nation approved an Energy Transition Law that many are now calling historic in scope and ambition....

Future Of The U S Space Program In Obama S Hands

As the moments tick away before tonight’s scheduled launch of the space shuttle Endeavour to the International Space Station (ISS), another countdown is underway: Only a handful of launches remain before the shuttle program’s scheduled retirement in 2010. When President-elect Barack Obama takes office two months from now, he and his aides will need to decide quickly whether or not to hold to that date, a determination that will have major implications for the future of U....

How I Built A 3 D Model Of The Coronavirus For Scientific American

What does SARS-CoV-2, the virus that causes COVID-19, look like? This simple question does not have a simple answer. SARS-CoV-2 is very small, and seeing it requires specialized scientific techniques. Electron microscopy (EM) can reveal its general size and shape. We can see that the virions are spherical or ellipsoidal, with “crowns” of spikes on their surfaces. Careful cryo-electron microscopy (cryo-EM) studies of many copies of the virion can reveal more precise measurements of the virus and its larger pieces....

In The Field A Biologist Who Counts Wild Yaks

PROFILE NAME Joel Berger TITLE Wildlife biologist, University of Montana and Wildlife Conservation Society LOCATION Missoula, Mont., and Bronx, N.Y. There are around 14 million domestic yaks in the world, but nobody knows how many wild yaks there are. They’re a vulnerable species. The Tibetan Himalayan region, their home, has tens of thousands of glaciers, and as the snow and the ice melt, we’re not sure what it’s going to do to yaks....

Is The Baby In Pain Brain Scans Can Tell

Pain in infants is heartbreaking for new parents, and extremely difficult to treat effectively—if at all. Every year an estimated 15 million babies are born prematurely, most of whom will then undergo numerous lifesaving but painful procedures, such as heel pricking or insertion of a thin tube known as a cannula to deliver fluids or medicine. Preterm babies in the intensive care unit are subjected to an average of 11 such “skin-breaking” procedures per day, but analgesia is only used just over one third of the time....

New Reactors May Be Needed For Climate Fight In U S

Rising temperatures around the world are a compelling argument for nuclear energy, industry advocates say. However, they acknowledge that existing nuclear energy technologies—and the corresponding policies—aren’t up to the job. “While nuclear can be a very large share of global demand and low carbon supply, we’re not going to do it, I believe, on the current generation of technology,” said Armond Cohen, executive director of the Clean Air Task Force. “My concern is these things take just too bloody long to build....

Newly Discovered Cell Type May Fuel Cystic Fibrosis

The discovery of a new type of cell could fundamentally alter how cystic fibrosis researchers seek a cure for the often-fatal hereditary disease. A paper published Wednesday in Nature describes how an ongoing cellular mapping project helped scientists identify this rare cell type, which appears to play a key role in managing rehydration and pH balance—huge issues for cystic fibrosis patients. A second paper in the same journal offers a similar finding....

Ocean Species Are Shifting Toward The Poles

For centuries, fishers in Narrangansett, R.I., have plied the waters of the northwestern Atlantic for herring—small, schooling fish that are also a staple for ocean predators. But as climate change warms the world’s seas, the herring these fishers rely on are vanishing at the southern end of their range and turning up more often at its northern edges. This situation is playing out in ocean waters the world over: concentrations of marine animal populations have been shifting away from the equator and toward the poles during the course of the past century, according to one of the most comprehensive analyses of marine species distributions to date....

Poor Countries Do More When It Comes To Saving Forests

That discovery is consistent with a trend observed by the environmental group for the climate submissions — known as intended nationally determined contributions, or INDCs — of a dozen forest-centric countries ahead of key U.N. climate change negotiations in Paris beginning this month. “The DRC is a very poor country, and it has a lot of difficulties in terms of making plans and implementing them, but they did a good job in their INDC,” said Doug Boucher, director of UCS’s Tropical Forest and Climate Initiative....

Prescribed Burns Are More Dangerous Because Of Climate Change

CLIMATEWIRE | The head of the Forest Service says in a new report that climate change is making prescribed fire increasingly dangerous even as the controlled burns remain essential for thinning the nation’s forests to prevent wildfire catastrophes. Forest Service Chief Randy Moore issued the warning Tuesday in a detailed report examining how a prescribed fire in northern New Mexico grew out of control this spring and became the largest wildfire in state history, consuming an area nearly twice the size of New York City....

Starlink Internet From Space And The Precarious Future Of Broadband In Rural America

The Hoh Tribe consists of 28 homes along a strip of road on the edge of Washington State’s Olympic Peninsula. Like in many rural parts of the U.S., getting online here has been a constant struggle. A few homes have wired Internet connectivity, but the download speeds are incredibly slow—barely enough to watch a YouTube video. Others rely on patchy cellular service. For years, community members have pleaded with telecom companies to provide their tribe with better Internet service....

Strong Clear Bioplastic Containers Could Be Made From Rice

Researchers in Finland have transformed rice starch into a temporally stable, optically transparent, biodegradable plastic with a high degree of mechanical strength and good thermal resistance. This important step towards bioplastics made from simple and sustainable resources has potential applications in food packaging and biomedical materials. Starch is a polysaccharide consisting of two components: a linear glucose polymer called amylose and a highly branched glucose polymer called amylopectin. Most green plants store their energy as starch and it is present in large quantities in grains such as maize, wheat and rice, in addition to tubers like potatoes....

Tapping The Expertise Of Patients

On a February day 15 years ago Paul Bradford took himself to a local emergency room. Bradford felt agitated and confused; he and his wife thought he needed professional help. To his surprise, two large men came into the waiting room, grabbed him by the arms and hustled him into a treatment room. Petrified, Bradford asked his wife to stay with him, but he says the security guards forced her out, tied him to a gurney and gave him a sedative that knocked him out for 18 hours....

The U S Is Not Ready To Clean Up An Arctic Oil Spill

The United States is not ready to clean up an oil spill in the Arctic, the head of the Coast Guard said yesterday. The warning comes as Congress prepares to open up more drilling in a region quickly being transformed by climate change. Adm. Paul Zukunft said that the challenges of cleaning up the BP PLC Deepwater Horizon oil spill in 2010 in the Gulf of Mexico—where the conditions were much more favorable—show the extreme difficulty of Arctic oil spill recovery....

Virgin Births Seen In Wild Vipers

By Brian Switek of Nature magazine It usually takes two snakes — a female and a male — to make a litter of baby copperheads. But research now shows that copperheads (Agkistrodon contortrix) and their venomous cousins cottonmouths (Agkistrodon piscivorus) don’t always require a partner to establish the next generation. These vipers are capable of virgin births. For some vertebrates, parthenogenesis — asexual reproduction in which embryos develop without fertilization — is the norm....

We Can T Allow The Cdc To Be Tainted By Politics

The CDC’s Mortality and Morbidity Weekly Report, familiarly known as the MMWR, has been around for nearly a century, and is sacrosanct in the public health community. Loaded with reliable, timely data and analyses and authored by the world’s top scientists, it is required reading, especially during a pandemic. To meddle with, delay or politicize these reports would be a form of scientific blasphemy as well as a breach of public trust that could undermine the nation’s efforts to fight the coronavirus....

When Doctors Advise Wait And See Worries Can Be Crippling

Imagine being told you have cancer or a potentially dangerous aneurysm—and then being told the best course of action might be to do nothing. This approach, dubbed “watchful waiting,” is the reality for an increasing number of patients, thanks to powerful new scanning tools. Yet coping with such uncertainty is difficult for most people. “As the technology gets better and better, we’re picking up more of these conditions way earlier than the disease would be symptomatic or dangerous,” says Shelley Hwang, a breast surgeon at Duke University Medical Center, whose practice includes some women who choose surveillance for a precancerous but risky breast condition....
