Biologists at UC San Diego have discovered that a small dose of a commonly used crop pesticide turns honey bees into "picky eaters" and affects their ability to recruit their nestmates to otherwise good sources of food. The results of their experiments, detailed in this week's issue of the Journal of Experimental Biology, have implications for what pesticides should be applied to bee-po
Marine scientists studying life around deep-sea vents have discovered that some hardy species can survive the extreme change in pressure that occurs when a research submersible rises to the surface. The team's findings, published in Conservation Biology, reveal how a species can be inadvertently carried by submersibles to new areas, with potentially damaging effects on marine ecosystems.
Calcium supplements might increase the risk of having a heart attack, and should be "taken with caution," concludes research published in the online issue of the journal Heart.
A study to evaluate birth control methods has found dramatic differences in their effectiveness. Women who used birth control pills, the patch or vaginal ring were 20 times more likely to have an unintended pregnancy than those who used longer-acting forms such as an intrauterine device (IUD) or implant.
Octopuses camouflage themselves by matching their body pattern to selected features of nearby objects, rather than trying to match the entire larger field of view, according to new research published in the open access journal PLoS ONE.

Long before babies understand the story of Goldilocks, they have more than mastered the fairy tale heroine's method of decision-making. Infants ignore information that is too simple or too complex, focusing instead on situations that are "just right," according to a new study to be published in the journal PLoS ONE on May 23.
A novel anti-inflammatory drug could help to improve survival in the most severe cases of malaria by preventing the immune system from causing irrevocable brain and tissue damage.
Antimicrobial peptides (AMPs) are molecules produced in the skin to fend off infection-causing microbes. Vitamin D has been credited with a role in their production and in the body's overall immune response, but scientists at the University of California, San Diego School of Medicine say a hormone previously associated only with maintaining calcium homeostasis and bone health is also critical, boo
UCLA life scientists have discovered new laws that determine the construction of leaf vein systems as leaves grow and evolve. These easy-to-apply mathematical rules can now be used to better predict the climates of the past using the fossil record.
New research out today on the long-term impact of species extinctions suggests that the disappearance of one species does not necessarily allow remaining competitor species to thrive by filling now-empty niches.
University of Michigan researchers have proven that a special surface, free of biological contaminants, allows adult-derived stem cells to thrive and transform into multiple cell types. Their success brings stem cell therapies another step closer.
Ultracold quantum gases are an ideal experimental model system to simulate physical phenomena in condensed matter. In these gases, many-body states can be realized under highly controlled conditions and interactions between particles are highly tuneable. A research group led by Wittgenstein awardee Rudolf Grimm and START awardee Florian Schreck have now realized and comprehensively analyzed repuls
The influence of the ground beneath us on the air around us could be greater than scientists had previously thought, according to new research that links the long-ago proliferation of oxygen in Earth's atmosphere to a sudden change in the inner workings of our planet.
Lunge feeding in rorqual whales (a group that includes blue, humpback and fin whales) is unique among mammals, but details of how it works have remained elusive. Now, scientists from the Smithsonian Institution and University of British Columbia have solved the mystery. They discovered a sensory organ in the chin of rorqual whales that communicates to the brain. The organ orchestrates the dramatic
The limitations of conventional and current solar cells include high production cost, low operating efficiency and durability, and many cells rely on toxic and scarce materials. Northwestern University researchers have developed a new solar cell that, in principle, will minimize all of these solar energy technology limitations.

Carbon capture and storage (CCS) projects around the world are hitting a wall in the face of high costs and a lack of climate policy.
HP Labs says the best office social networks require no effort. Social networks like Facebook and Twitter work well because people enjoy sharing their lives with friends. At the office, however, social networking with colleagues can feel forced. Many businesses are adopting social-networking tools in hopes of fostering collaboration, but if employees don't sign up or participate, the effort fails.
A kit containing 600 to 700 parts, including Kinect hardware and software, was used to build basketball-shooting robots.
Humans love to line up in front of the glass walls at penguin zoo exhibits, staring at the antics of the black-and-white, two-legged creatures. But what about when the tides are turned, when penguins get a chance to meet the strange humans, observing them...
