Wearing a computer on your sleeve may be a lot cooler than a plastic watch with an Apple logo on it - researchers at the University of Pittsburgh have designed a responsive hybrid material fueled by an oscillatory chemical reactions.
They can even perform computations based on changes in the environment or movement, and respond to human vital signs. The material system is sufficiently small and flexible enough to be integrated into fabric or introduced as an inset into a shoe.
The entry refers to I Write What I Like, a volume of collected writings by Steve Biko, the Black Consciousness leader tortured to death in police custody in 1977.
The library used to have six copies of the volume but they have all been borrowed and never returned.
Scientists have developed a computer model that clarifies the complex processes driving ocean mixing in the vast eddies that swirl across hundreds of miles of open ocean.
The Lagrangian In-situ, Global, High-performance particle Tracking (LIGHT) model is a first-of-its-kind tool because of its ability to exploit the power available from today's supercomputers, the authors say.
Was America at its greatest scientifically when academics made far less money and were politically representative? Not if science output, Nobel prizes and adult science literacy are the measures, because America leads in all categories.
Yet with six figure incomes for faculty and less diversity has come greater distrust. Conservatives, for example, once had the highest trust in science, and now they are near the lowest, along with progressives. The public regularly thinks that anyone who cashes a paycheck is unethical, people don't trust medicine, food or energy science on the left and the right thinks climate scientists are shills.
Recent research has reignited concerns that exposure to chemicals from plastics might be to blame for low sperm counts in young men. I share the concerns about the high prevalence of low sperm counts (one in six young men), and my research is directed at trying to identify what causes it. But whether plastics are to blame isn’t a simple matter.-->
We can blame smartphone alerts, constant connectivity and a deluge of media for sleep deprivation but that is talking about the symptoms rather than the disease. The root cause is instead the thing that has led to cultural and social improvements for over 100 years - artificial light.
Salmon are severely impacted by the loss of floodplain habitats near Oregon's Tillamook Bay, where nearly 90 percent of estuaries' tidal wetlands have been lost to development -- threatening the survival of coho salmon and the safety of the local community. Now, the Federal Emergency Management Agency, NOAA Fisheries, and others have come together to reduce flood risk, increase resiliency of the ecosystem, and restore salmon habitat in Tillamook Bay under the auspices of The Southern Flow Corridor project, as the proposed collaborative effort is known. It will reconnect over 500 acres of floodplain habitat to two of the Bay's most productive salmon-bearing streams -- the Wilson and Trask Rivers.
A simple and provocative title – The Missing Memristor has Not been Found! This harsh admission of reality without sugar coating is the very title, and not of some opinion piece, but of a scientific paper published by the very same Nature Publishing Group that is criticized right away in that very paper:
Children are more likely to have a repeat, delayed anaphylactic reaction from the same allergic cause, depending on the severity of the initial reaction.
Anaphylaxis is a severe, allergic reaction that is rapid in onset and can result in death. Some children are at risk of delayed ('biphasic') anaphylactic reactions. Delayed reactions occur when the initial symptoms of allergic reaction go away but then return hours or days later without exposure to the initial substance that caused the reaction.
Researchers have successfully stopped cocaine and alcohol addiction in experiments using a drug already approved by the U.S. Food and Drug Administration (FDA) to treat high blood pressure. If the treatment is proven effective in humans, it would be the first of its kind -- one that could help prevent relapses by erasing the unconscious memories that underlie addiction.
Scientists once believed that drug addiction was simply a physical craving: Drug addicts who became sober and then later relapsed merely lacked willpower. But that view has gradually shifted since the 1970s.
A new test can accurately predict within minutes if an individual has Ebola and is the first to show that a point-of-care EVD test is faster than and as sensitive as a conventional laboratory-based molecular method used for clinical testing during the recent outbreak in Sierra Leone.
This new rapid diagnostic test could cut back on the lengthy process usually required to confirm if a patient has Ebola, help identify case contacts, and ultimately curb the spread.
Are some people unable or unwilling to quit? A popular sociological belief has been that by making smoking uncool or difficult, it will become unpopular and people will quit, and only those unable to quit would remain. If so, products like e-cigarettes or smokeless tobacco make sense as alternatives.
