| Out of an hours-long explosion, a stand-in for the first stars Posted: 11 Jul 2014 12:33 PM PDT Astronomers analyzing a long-lasting blast of high-energy light observed in 2013 report finding features strikingly similar to those expected from an explosion from the universe's earliest stars. If this interpretation is correct, the outburst validates ideas about a recently identified class of gamma-ray burst and serves as a stand-in for what future observatories may see as the last acts of the first stars. |
| Posted: 11 Jul 2014 10:28 AM PDT Lighting is crucial to the art of photography. But lights are cumbersome and time-consuming to set up, and outside the studio, it can be prohibitively difficult to position them where, ideally, they ought to go. |
| Baboons groom early in day to get benefits later Posted: 11 Jul 2014 07:13 AM PDT Social animals often develop relationships with other group members to reduce aggression and gain access to scarce resources. In wild chacma baboons the strategy for grooming activities shows a certain pattern across the day. new insights highlight the importance of understanding the full range of time periods over which social strategies may be optimized. Such knowledge is crucial when studying the social behavior and strategies of group-living animals. |
| Do women perceive other women in red as more sexually receptive? Posted: 11 Jul 2014 06:21 AM PDT Women are more likely to wear a red shirt when they are expecting to meet an attractive man, relative to an unattractive man or a woman. But do women view other women in red as being more sexually receptive? And would that result in a woman guarding her mate against a woman in red? A study has sought to answer these questions. |
| Potent spider toxin 'electrocutes' German, not American, cockroaches Posted: 11 Jul 2014 06:18 AM PDT Using spider toxins to study the proteins that let nerve cells send out electrical signals, researchers say they have stumbled upon a biological tactic that may offer a new way to protect crops from insect plagues in a safe and environmentally responsible way. |
| Ocean's most abundant organisms have clear daily cycles Posted: 10 Jul 2014 11:15 AM PDT In every drop of ocean water, hundreds of types of bacteria can be found. Now scientists have discovered that communities of these ocean microbes have their own daily cycles -- not unlike the residents of a bustling city who tend to wake up, commute, work, and eat at the same times. What's more, it's not all about the sun. These bacteria have been observed turning on diel cycling genes at slightly different times -— suggesting a wave of transcriptional activity that passes through the microbial community each day. |
| Injectable foam could prevent fatal blood loss in wounded soldiers Posted: 10 Jul 2014 08:15 AM PDT A student-invented battlefield medical device has potential to save soldiers with deep wounds, especially at the neck, shoulder or groin. Without prompt care, a badly wounded soldier can easily bleed to death while being transported to a distant medical station. Tourniquets and medicated gauze pads often cannot stop the blood loss from a deep wound at the neck, shoulder or groin. To give these soldiers a fighting chance at survival, an injectable foam system designed to stop profuse bleeding from a wound has been developed. |
