Herschel discovers mature galaxies in the young Universe Posted: 29 Apr 2014 03:36 PM PDT New Herschel results have given us a remarkable insight into the internal dynamics of two young galaxies. Surprisingly, they have shown that just a few billion years after the Big Bang, some galaxies were rotating in a mature way, seemingly having completed the accumulation of their gas reservoirs.

Mother's diet affects the 'silencing' of her child's genes Posted: 29 Apr 2014 09:57 AM PDT A unique 'experiment of nature' that took place in The Gambia has now revealed that a mother's diet before she conceives has a permanent effect on her offspring's genetics. This is the first time the effect has been seen in humans, and is regarded as a major contribution to the field of 'epigenetics.'

Depression detectable in the blood: Platelet serotonin transporter function Posted: 29 Apr 2014 07:50 AM PDT The possibility of using a blood test to detect depression has been demonstrated by researchers. While blood tests for mental illnesses have until recently been regarded as impossible, a recent study clearly indicates that, in principle, depression can in fact be diagnosed in this way and this could become reality in the not too distant future.

Bacteria on the skin: Our invisible companions influence how quickly wounds heal Posted: 28 Apr 2014 06:02 PM PDT A new study suggests microbes living on our skin influence how quickly wounds heal. The findings could lead to new treatments for chronic wounds, which affect 1 in 20 elderly people. We spend our lives covered head-to-toe in a thin veneer of bacteria. But despite a growing appreciation for the valuable roles our resident microbes play in the digestive tract, little is known about the bacteria that reside in and on our skin.

Multilayer, microscale solar cells enable ultrahigh efficiency power generation Posted: 28 Apr 2014 09:11 AM PDT A printing approach allows manipulation of ultrathin, small semiconductor elements that can be stacked on top of one another to yield an unusual type of solar cell capable of operating across the entire solar spectrum at exceptionally high efficiency.

Strategic thinking strengthens intellectual capacity Posted: 28 Apr 2014 06:42 AM PDT Strategy-based cognitive training has the potential to enhance cognitive performance and spill over to real-life benefit according to a data-driven perspective article. The research-based perspective highlights cognitive, neural and real-life changes measured in randomized clinical trials that compared a gist-reasoning strategy-training program to memory training in populations ranging from teenagers to healthy older adults, individuals with brain injury to those at-risk for Alzheimer's disease.

Mite sets new record as world's fastest land animal Posted: 27 Apr 2014 04:11 PM PDT A Southern California mite far outpaces the Australian tiger beetle, the current record-holder for running speed as measured in body lengths per second. By this measure, the mite runs 20 times faster than a cheetah and the equivalent of a person running 1300 miles per hour. The discovery is exciting not only because it sets a new world record, but also for what it reveals about the physiology of movement and the physical limitations of living structures, the researcher says.

What lies beneath modern New England? Mountain-building and the end of an ancient ocean Posted: 26 Apr 2014 12:53 PM PDT When and where did the ancient Iapetus Ocean suture (the most fundamental Appalachian structure) form? Is part of New England made up of ancient African-derived rocks? What is the Moretown terrane? A new study finds new evidence for an earlier closing of the Iapetus that is farther west than previous studies have reported.

Nitrogen pollution, climate and land use: Why what we eat matters Posted: 25 Apr 2014 06:36 AM PDT A new report quantifies for the first time how much our food choices affect pollutant nitrogen emissions, climate change and land-use across Europe. The Special report provides an assessment of what would happen if Europe were to decrease its consumption of meat and dairy products.

Oops! Researchers find neural signature for mistake correction Posted: 24 Apr 2014 09:50 AM PDT Researchers have captured an elusive brain signal underlying memory transfer and, in doing so, pinpointed the first neural circuit for "oops" -- the precise moment when one becomes consciously aware of a self-made mistake and takes corrective action. The findings verified a 20-year-old hypothesis on how brain areas communicate.
