| Boost fundraising with something simple: Sandpaper Posted: 25 Mar 2016 06:37 AM PDT Researchers have discovered that touching rough surfaces increases awareness of discomfort in our surroundings, which can trigger empathy. This leads to more interest in donating to charities. |
| The first 3-D atlas of the extinct dodo Posted: 25 Mar 2016 06:36 AM PDT For the first time since its extinction, a 3-D atlas of the skeletal anatomy of the dodo has been created, based upon two exceptional dodo skeletons that have remained unstudied for over a century. This atlas represents the culmination of nearly five years of work and thousands of human-hours of digital investigation on the only two associated, near-complete skeletons of the dodo in existence. |
| Antarctic birds recognize individual humans Posted: 25 Mar 2016 06:36 AM PDT Brown skuas in Antarctica can discriminate individual people, even though they normally do not see many people around. Scientists studied brown skuas living in Antarctica. |
| Parents think life quality is worse for teens, adults born very premature Posted: 25 Mar 2016 06:36 AM PDT Parents of very premature babies are more worried about their grown up children's lives than mothers and fathers whose babies were born full term. |
| Wnt secretion preventing drugs may reduce renal fibrosis, study shows Posted: 25 Mar 2016 06:36 AM PDT Renal fibrosis or the scarring of kidneys, following an injury, reduces their function and can cause kidney disease to progressively worsen. In a recent study, researchers have shown that drugs that target Wnt secretion by inhibiting Porcupine, a protein usually targeted for cancer treatment, may reduce renal fibrosis and protect the kidneys. |
| Self-repairing cancer cells future of cancer treatments Posted: 24 Mar 2016 12:01 PM PDT A research group has been studying cancer cells' ability to migrate through to tight spaces and self-repair to develop both treatment and diagnostic solutions for the millions of people who deal with cancer every day. |
| Researcher improves crop performance with new biotechnology Posted: 24 Mar 2016 11:59 AM PDT Researchers have discovered a way to enhance a plant's tolerance to stress, which in turn improves how it uses water and nutrients from the soil. These improvements increase plant biomass and yield. This discovery could be instrumental in agriculture and food security by improving crop sustainability and performance. |
| Solar cell material can recycle light to boost efficiency Posted: 24 Mar 2016 11:54 AM PDT Scientists have discovered that a highly promising group of materials known as hybrid lead halide perovskites can recycle light -- a finding that they believe could lead to large gains in the efficiency of solar cells. |
