| Eight new planets found in 'Goldilocks' zone: Two are most similar to Earth of any known exoplanets Posted: 06 Jan 2015 10:46 AM PST Astronomers announced today that they have found eight new planets in the 'Goldilocks' zone of their stars, orbiting at a distance where liquid water can exist on the planet's surface. This doubles the number of small planets (less than twice the diameter of Earth) believed to be in the habitable zone of their parent stars. Among these eight, the team identified two that are the most similar to Earth of any known exoplanets to date. |
| Of flies and ants: New ant decapitation behavior of Dohrniphora flies Posted: 06 Jan 2015 06:50 AM PST While watching tiny flies in tropical forests in Brazil, Giar-Ann Kung puzzledly remarked to Brian Brown 'they are cutting the ant heads off!' This unexpected find led to the discovery of a grisly new type of behavior. |
| Posted: 06 Jan 2015 06:50 AM PST For a skin cell to do its job, it must turn on a completely different set of genes than a liver cell -- and keep genes it doesn't need switched off. One way of turning off large groups of genes at once is to send them to 'time-out' at the edge of the nucleus. New research shows how DNA gets sent to the nucleus' far edge, a process critical to controlling genes and determining cell fate. |
| New technology enables ultra-fast steering and shaping of light beams Posted: 06 Jan 2015 06:50 AM PST A team of engineers has developed a new acousto-optic device that can shape and steer beams of light at speeds never before achieved. |
| 'Imaginary meal' tricks body into losing weight Posted: 05 Jan 2015 08:27 AM PST A more effective diet pill has been developed by scientists. Unlike most diet pills on the market, this new pill, called fexaramine, doesn't dissolve into the blood like appetite suppressants or caffeine-based diet drugs, but remains in the intestines, causing fewer side effects, like an "imaginary meal," the researchers explain. |
| The bowhead whale lives over 200 years: Can its genes tell us why? Posted: 05 Jan 2015 07:14 AM PST A whale that can live over 200 years with little evidence of age-related disease may provide untapped insights into how to live a long and healthy life. Researchers present in a new report the complete bowhead whale genome and identify key differences compared to other mammals. Alterations in bowhead genes related to cell division, DNA repair, cancer, and aging may have helped increase its longevity and cancer resistance. |
