To fight nasty digestive bugs, scientists set out to build a better gut – using stem cells

Science Daily - Fri, 17/04/2015 - 2:34pm
If you’ve ever been hit with an ‘intestinal bug’, you’ve felt the effects of infectious microbes on your digestive system. But scientists don’t fully understand what’s going on in gut infections like that – or in far more serious ones. Now, a team of scientists will tackle that issue in a new way.

How radiative fluxes are affected by cloud and particle characteristics

Science Daily - Fri, 17/04/2015 - 2:34pm
Climate models calculate a changing mix of clouds and emissions that interact with solar energy. To narrow the broad range of possible answers from a climate model, researchers analyzed the effect of several proven numerical stand-ins for atmospheric processes on the energy flux at the top of the atmosphere. They found that the flux is the main driver of surface temperature change.

Breakthrough In Artificial Photosynthesis Captures CO2 In Acetate

Slashdot - Fri, 17/04/2015 - 2:12pm
An anonymous reader writes: Researchers from Berkeley Lab and the U.S. Dept. of Energy have created an artificial photosynthetic process that capture carbon dioxide in acetate, "the most common building block today for biosynthesis." The research has been published in the journal Nano Letters (abstract). "Atmospheric carbon dioxide is now at its highest level in at least three million years, primarily as a result of the burning of fossil fuels. Yet fossil fuels, especially coal, will remain a significant source of energy to meet human needs for the foreseeable future. Technologies for sequestering carbon before it escapes into the atmosphere are being pursued but all require the captured carbon to be stored, a requirement that comes with its own environmental challenges. ... By combining biocompatible light-capturing nanowire arrays with select bacterial populations, the new artificial photosynthesis system offers a win/win situation for the environment: solar-powered green chemistry using sequestered carbon dioxide."

Scientists Close To Solving the Mystery of Where Dogs Came From

Slashdot - Fri, 17/04/2015 - 1:30pm
sciencehabit writes: For years researchers have argued over where and when dogs arose. Some say Europe, some say Asia. Some say 15,000 years ago, some say more than 30,000 years ago. Now an unprecedented collaboration of archaeologists and geneticists from around the world is attempting to solve the mystery once and for all. They're analyzing thousands of bones, employing new technologies, and trying to put aside years of bad blood and bruised egos. If the effort succeeds, the former competitors will uncover the history of man's oldest friend — and solve one of the greatest mysteries of domestication.

Smokers underestimate risks of a few cigarettes

Science Daily - Fri, 17/04/2015 - 12:54pm
Many people still dangerously underestimate the health risks associated with smoking even a few cigarettes a day, despite decades of public health campaigning, researchers report. "People who smoke very much tend to underestimate their risks," an investigator said, "and it makes me think that 'denial' is still prevalent. As an oncologist and tobacco control advocate, it amazes me and strikes me as so unfortunate that such lack of knowledge is so prevalent."
