| Novel state of matter: Observation of a quantum spin liquid Posted: 26 Jul 2016 09:33 AM PDT A novel and rare state of matter known as a quantum spin liquid has been empirically demonstrated in a monocrystal of the compound calcium-chromium oxide. According to conventional understanding, a quantum spin liquid should not be possible in this material. A theoretical explanation for these observations has now also been developed. |
| Sexual rivalry may drive frog reproductive behaviors Posted: 26 Jul 2016 09:29 AM PDT Biologists have long thought that some frogs evolved to mate on land instead of in water to better guard eggs and tadpoles from predation. New research now suggests that mating on land in many species might be a strategy male frogs use to ensure that their own DNA gets passed on, instead of their rivals'. Sexual selection may trump natural selection in the evolution of these reproductive behaviors. |
| Americans worried about using gene editing, brain chip implants and synthetic blood Posted: 26 Jul 2016 09:28 AM PDT Many in the general public think scientific and technological innovations bring helpful change to society, but they are more concerned than excited when it comes to the potential use of emerging technologies to make people's minds sharper, their bodies stronger and healthier than ever before, according to a new survey. A majority of Americans would be 'very' or 'somewhat' worried about gene editing (68%); brain chips (69%); and synthetic blood (63%), while no more than half say they would be enthusiastic about each of these developments. While some people say they would be both enthusiastic and worried, overall, concern outpaces excitement. |
| Postcards provide link to Edwardian social media Posted: 26 Jul 2016 06:48 AM PDT A new public searchable database provides access to a unique and inspirational treasure trove of amazing stories and pictures through what researchers term the 'social media' of the Edwardian era. |
| Any picture or text could be inkjet-printed as a solar cell Posted: 26 Jul 2016 06:44 AM PDT Any picture or text could be inkjet-printed as a solar cell, using a newly developed technology. When light is absorbed in an ordinary ink, it generates heat. A photovoltaic ink, however, coverts part of that energy to electricity. The darker the color, the more electricity is produced, because the human eye is most sensitive to that part of the solar radiation spectrum which has highest energy density. |
| Height rankings revealed: Dutch men and Latvian women tallest in world Posted: 26 Jul 2016 06:44 AM PDT Dutch men and Latvian women are the tallest on the planet, according to the largest ever study of height around the world. |
| Japanese tadpoles relax in hot springs Posted: 26 Jul 2016 06:43 AM PDT Japanese tadpoles can live and grow in natural hots springs, or onsen, with water temperatures as high as 46.1oC (115oF). Living in onsen may benefit the tadpoles' immune systems, speed their growth, and allow the tadpoles to survive on small volcanic islands where there are few other natural sources of fresh water. |
| Historical love-affair with indulgent foods Posted: 26 Jul 2016 06:41 AM PDT Our desire for indulgent meals may be over 500 years old. A new analysis of European and American paintings across five centuries shows that salt, bread, sausage, and shellfish were among the most commonly depicted foods in paintings of meals from 1500 to 2000 AD. |
