The importance of beating buffering Posted: 14 Jan 2017 04:11 PM PST Streaming video over mobile networks could be greatly improved by smart prioritization of visually important data, report investigators.

A breath of fresh air: Improving zinc-air batteries Posted: 14 Jan 2017 04:11 PM PST A three-layer nanoparticle catalysts improve zinc-air batteries, report scientists.

Scientists reprogram embryonic stem cells to expand their potential cell fates Posted: 13 Jan 2017 04:44 PM PST Pluripotent stem cells can develop into most tissues of the organism, but they cannot develop into extra-embryonic tissue -- the placenta or yolk sac, for example --- like the one-celled fertilized egg or two-celled zygote. Researchers found that by blocking a specific microRNA, pluripotent stem cells can regain the ability to become extra-embryonic tissue, providing a way to expand the developmental potential of iPC cells with implications for regenerative medicine and stem cell-based therapies.

Soil fungi help tree seedlings survive, influence forest diversity Posted: 13 Jan 2017 04:44 PM PST The relationship between soil fungi and tree seedlings is more complicated than previously known, new research shows.

New technology enables 5-D imaging in live animals, humans Posted: 13 Jan 2017 12:56 PM PST A computer algorithm for analyzing time-lapse biological images could make it easier for scientists and clinicians to find and track multiple molecules in living organisms, outlines a new report. The technique developed by an international team of scientists is faster, less expensive and more accurate than current imaging methods that can identify signs of disease.

Composite material for water purification Posted: 13 Jan 2017 12:54 PM PST Fresh, clean water coming directly from the tap is a true luxury. In developing countries, people often have no choice but to use a contaminated river for drinking water. Water filters can help by quickly converting polluted surface or ground water into safe drinking water. In a new article, researchers have now introduced a novel multifunctional composite material that removes inorganic, organic, radioactive, and microbial impurities from water.

Your cell phone could curb the intensity of your workout Posted: 13 Jan 2017 12:54 PM PST Talking or texting on a cell phone during exercise will lower the intensity of a workout and also affect balance, new research shows.

Arabica coffee genome sequenced Posted: 13 Jan 2017 12:53 PM PST The sequencing of the genome of Coffea arabica, the species responsible for more than 70 percent of global coffee production, has now been announced by researchers.

Environmentally-friendly soy air filter developed Posted: 13 Jan 2017 12:53 PM PST A new soy-based air filter can capture toxic chemicals such as carbon monoxide and formaldehyde, which often escape other types of filters.

Thinking of changing your behavior in 2017? Try moving first Posted: 13 Jan 2017 12:53 PM PST The time for successful habit change isn't based on the calendar, but on big changes to our everyday lives like moving to a new home, new research shows.

Found: Neurons that orient bats toward destination Posted: 12 Jan 2017 01:25 PM PST Bats – like humans – can find their favorite fruit stand (or coffee shop) even when it's hidden behind a screen or tall buildings. How? Scientists have now identified the neurons that point bats in the right direction, even when their destination is obscured. This could aid understanding of some aspects of Alzheimer's.

Vader systems creates liquid metal 3-D printer for manufacturing Posted: 12 Jan 2017 01:21 PM PST A father and son team have created a liquid metal 3-D printing machine that could represent a significant transformation in manufacturing. The machine is so novel it represents a quantum leap in the ability to print three-dimensional objects in metal. Other metal printers exist, but most use a process of laying down powered metal and melting it with a laser or electron beam.

Two-thirds of packaged foods, drinks in Canada have added sugars Posted: 12 Jan 2017 11:14 AM PST An analysis of over 40,000 commonly available packaged foods and beverages in Canada has found that 66 percent of these products -- including some infant formulas and baby food products and many so-called 'healthier' foods such as yogurt, juice, breakfast cereals, and snack bars -- have at least one added sugar in their ingredients list, according to new research.

Markers for prostate cancer death can identify men in need of more aggressive treatment Posted: 12 Jan 2017 11:14 AM PST A prostate specific antigen (PSA) nadir greater than 0.5 ng/mL following radiation and androgen deprivation therapy appears to identify men prior to PSA failure who are at high-risk for dying early as a result of treatment failure for their prostate cancer, research shows.

Melanoma mutation likes fat for fuel Posted: 12 Jan 2017 11:13 AM PST Cancer cells love glucose, so a high-fat, low-carb diet should starve them, right? Not cancers driven by a notorious melanoma mutation. Research in mice suggests that cancers with BRAF V600E will grow faster in response to a high-fat 'ketogenic' diet. In addition, lipid-lowering agents such as statins curb these cancers' growth, even in the context of a more normal diet.

Some cells need a 'haircut' before duplicating Posted: 12 Jan 2017 11:13 AM PST Many of our cells are equipped with a hairlike 'antenna' that relays information about the external environment to the cell, and scientists have already discovered that the appearance and disappearance of these so-called primary cilia are synchronized with the process of cellular duplication, called mitosis.

Seeing vape pen in use boosts desire to smoke among young adults Posted: 12 Jan 2017 11:13 AM PST The newer e-cigarette vape pens (AKA vaporizers) may not look like cigarettes, but they stimulate the urge to smoke as powerfully as watching someone smoke a traditional tobacco cigarette.

Ocean acidification to hit West Coast Dungeness crab fishery, new assessment shows Posted: 12 Jan 2017 11:13 AM PST The acidification of the ocean expected as seawater absorbs increasing amounts of carbon dioxide from the atmosphere will reverberate through the West Coast's marine food web, but not necessarily in the ways you might expect, new research shows.
