Study shows snakes, thought to be solitary eaters, coordinate hunts
Snakes, although as social as birds and mammals, have long been thought to be solitary hunters and eaters. A new study from the University of Tennessee, Knoxville, shows that some snakes coordinate their hunts to increase their chances of success.

Declawing linked to aggression and other abnormal behaviors in cats
Declaw surgery (onychectomy) is illegal in many countries but is still a surprisingly common practice in some. It is performed electively to stop cats from damaging furniture, or as a means of avoiding scratches. Previous research has focused on short-term issues following surgery, such as lameness, chewing of toes and infection, but the long-term health effects of this procedure have not to date been investigated.

Cowbird moms choosy when selecting foster parents for their young
Brown-headed cowbirds are unconventional mothers. Rather than building nests and nurturing their chicks, they lay their eggs in the nests of other species, leaving their young ones to compete for resources with the foster parents' own hatchlings. Despite their reputation as uncaring, absentee moms, cowbird mothers are capable of making sophisticated choices among potential nests in order to give their offspring a better chance of thriving, a new study shows.

Study: Street gangs, crime serve as deviant leisure activities for youths
Although at-risk youths may have a variety of reasons for joining street gangs, a new study suggests that gang membership and criminal acts often serve as deviant leisure activities, fulfilling young people's needs for excitement, a sense of belonging and social support.

Herpetologists describe an elf frog from the elfin forests in southern Vietnam

Going under the common name of Elfin mountain toad, a new amphibian is recognized as one of the smallest representative of its group. The new species was identified from the highland wet forests of Langbian Plateau, Southern Vietnam. The discoverers gave it this name that derives from German and Celtic folklore because of the resemblance they found between the tiny delicate amphibians and elves - small magic creatures. Furthermore, their habitat is known as elfin forests.

Iron deficiency restrains marine microbes

Iron is a critical nutrient in the ocean. Its importance for algae and the nitrogen cycle has already been investigated in detail. Now a new discovery shows that microbes also need iron to process phosphorus. A team of researchers has completed a study showing that iron can limit phosphorus acquisition in the ocean. Their study contributes to knowledge of nutrient cycling in the ocean.

New coral reef fish species shows rare parental care behavior

The vast majority of coral reef fish produce large numbers of young that disperse into the ocean as larvae, drifting with the currents before settling down on a reef. A few reef fish, however keep their broods on the reef, protecting the young until they are big enough to fend for themselves. On a recent trip to the Philippines, researchers discovered a new species of damselfish that exhibits this unusual parental care behavior.

Fake caterpillar study reveals global pattern in predation

A new study revealing the world's prime insect predation hotspots, achieved its landmark findings using an unusual aid: plasticine 'dummy caterpillars.' The new study has revealed a global pattern of predation on insect herbivores. The trends observed were surprising, revealing that predatory behavior in the tropics is not driven by birds or mammals but by ants and other small arthropods.

Antarctic has seen widespread change in last 50 years, moss study reveals

In 2013, researchers studying mosses and microbes growing at the southern end of the Antarctic Peninsula documented unprecedented ecological change over the last 50 years, driven by warming temperatures. Now, the same research group has confirmed that those striking changes in the Antarctic are widespread, occurring all across the Peninsula.

Atomic structure of irradiated materials is more akin to liquid than glass
Materials exposed to neutron radiation tend to experience significant damage, leading to the containment challenges involved in immobilizing nuclear waste or nuclear plant confinements. At the nanoscale, these incident neutrons collide with a material's atoms that, in turn, then collide with each other somewhat akin to billiards. The resulting disordered atomic network and its physical properties resemble those seen in some glassy materials, which has led many in the field to use them in nuclear research.

Understanding stars: How tornado-shaped flow in a dynamo strengthens the magnetic field
The massive, churning core of conducting liquids in stars and some planets creates a dynamo that generates the planetary body's magnetic field. Researchers aim to better understand these dynamos through computer simulations and by recreating them in the laboratory using canisters of rapidly spinning, liquid sodium.

New blackbody force depends on spacetime geometry and topology
(Phys.org)—In 2013, a group of physicists from Austria proposed the existence of a new and unusual force called the "blackbody force." Blackbodies—objects that absorb all incoming light and therefore appear black at room temperature—have long been known to emit blackbody radiation, which repels small nearby objects such as atoms and molecules. But the physicists showed that blackbodies theoretically also exert an attractive force on these objects. They called this force the "blackbody force," and showed that it can be stronger than blackbody radiation, and—for very small particles—even stronger than gravity.
