Hi-ho! Astronomers discover seven dwarf galaxies with new telescope Posted: 10 Jul 2014 03:36 PM PDT Meet the seven new dwarf galaxies. Astronomers, using a new type of telescope made by stitching together telephoto lenses, recently discovered seven celestial surprises while probing a nearby spiral galaxy. The previously unseen galaxies may yield important insights into dark matter and galaxy evolution, while possibly signaling the discovery of a new class of objects in space.

NASA spacecraft observes further evidence of dry ice gullies on Mars Posted: 10 Jul 2014 03:30 PM PDT Repeated high-resolution observations made by NASA's Mars Reconnaissance Orbiter (MRO) indicate the gullies on Mars' surface are primarily formed by the seasonal freezing of carbon dioxide, not liquid water. The first reports of formative gullies on Mars in 2000 generated excitement and headlines because they suggested the presence of liquid water on the Red Planet, the eroding action of which forms gullies here on Earth. Mars has water vapor and plenty of frozen water, but the presence of liquid water on the neighboring planet, a necessity for all known life, has not been confirmed.

DARPA taps Lawrence Livermore to develop world's first neural device to restore memory Posted: 10 Jul 2014 02:53 PM PDT The Department of Defense's Defense Advanced Research Projects Agency (DARPA) awarded Lawrence Livermore National Laboratory (LLNL) up to $2.5 million to develop an implantable neural device with the ability to record and stimulate neurons within the brain to help restore memory, DARPA officials announced this week.

'Mississippi Baby' now has detectable HIV, researchers find Posted: 10 Jul 2014 12:19 PM PDT The child known as the 'Mississippi baby' -- an infant seemingly cured of HIV that was reported as a case study of a prolonged remission of HIV infection in the New England Journal of Medicine last fall -- now has detectable levels of HIV after more than two years of not taking antiretroviral therapy without evidence of virus, according to the pediatric HIV specialist and researchers involved in the case.

Drinking alcohol provides no heart health benefit, new study shows Posted: 10 Jul 2014 12:19 PM PDT Reducing the amount of alcoholic beverages consumed, even for light-to-moderate drinkers, may improve cardiovascular health, including a reduced risk of coronary heart disease, lower body mass index and blood pressure, according to a new multi-center study. The latest findings call into question previous studies which suggest that consuming light-to-moderate amounts of alcohol may have a protective effect on cardiovascular health.

What you eat may affect your body's internal biological clock Posted: 10 Jul 2014 10:08 AM PDT Food not only nourishes the body but also affects its internal biological clock, which regulates the daily rhythm of many aspects of human behavior and biology. Researchers provide new insights into how adjusting the clock through dietary manipulation may help patients with various conditions and show that insulin may be involved in resetting the clock.

Chimp intelligence 'runs in families,' environment less important Posted: 10 Jul 2014 10:05 AM PDT A chimpanzee's intelligence is largely determined by its genes, while environmental factors may be less important than scientists previously thought, according to a Georgia State University research study.

One secret of ancient amber revealed Posted: 09 Jul 2014 11:02 AM PDT The warm beauty of amber was captivating and mysterious enough to inspire myths in ancient times, and even today, some of its secrets remain locked inside the fossilized tree resin. But for the first time, scientists have now solved at least one of its puzzles that had perplexed them for decades.

A dominant hemisphere for handedness and language? Posted: 04 Jul 2014 10:46 AM PDT Through an innovative approach using a large psychometric and brain imaging database, researchers have demonstrated that the location of language areas in the brain is independent of left- or right-handedness, except for a very small proportion of left-handed individuals whose right hemisphere is dominant for both manual work and language.
