Mantis shrimp stronger than airplanes: Composite material inspired by shrimp stronger than standard used in airplane frames
Inspired by the fist-like club of a mantis shrimp, researchers have developed a design structure for composite materials that is more impact resistant and tougher than the standard used in airplanes. The peacock mantis shrimp, or stomatopod, is a 4- to 6-inch-long rainbow-colored crustacean with a fist-like club that accelerates underwater faster than a 22-calibur bullet.

A new 'APEX' in plant studies aboard the International Space Station
Growing knowledge in a given field takes time, attention, and ... water? It does when you're talking about plant studies aboard the International Space Station (ISS). All of these things and some scientific know-how come into play as astronauts find out just how green their thumbs are while assisting researchers on the ground.

For an immune cell, microgravity mimics aging
Telling someone to "act your age" is another way of asking him or her to behave better. Age, however, does not always bring improvements. Certain cells of the immune system tend to misbehave with age, leaving the elderly more vulnerable to illness. Because these cells are known to misbehave similarly during spaceflight, researchers are studying the effects of microgravity on immune cells to better understand how our immune systems change as we age.

Is nuclear power the only way to avoid geoengineering?
(SAGE Publications) 'I think one can argue that if we were to follow a strong nuclear energy pathway -- as well as doing everything else that we can -- then we can solve the climate problem without doing geoengineering.' So says Tom Wigley, one of the world's foremost climate researchers, in the current issue of Bulletin of the Atomic Scientists, published by SAGE.

Norovirus in food outlets to be mapped for the first time
(University of Liverpool) The University of Liverpool is leading a £2 million Food Standards Agency project to map the occurrence of norovirus in food premises and industry workers.

Cell division speed influences gene architecture
(Instituto Gulbenkian de Ciencia) Biological systems are sometimes under selective pressure to quickly 'read' genetic information. Genes that need to be read quickly are usually small. Now, researchers from Instituto Gulbenkian de Ciência and Centre for Molecular and Structural Biomedicine discovered that, besides size, the gene architecture is also important to the optimization of the 'reading' process. This study was now published in the open access scientific journal eLife.

Scientists identify critical new protein complex involved in learning and memory

Scientists from the Florida campus of The Scripps Research Institute (TSRI) have identified a protein complex that plays a critical but previously unknown role in learning and memory formation.

International team sequences rainbow trout genome

Using fish bred at Washington State University, an international team of researchers has mapped the genetic profile of the rainbow trout, a versatile salmonid whose relatively recent genetic history opens a window into how vertebrates evolve.

Bioinformatics profiling identifies a new mammalian clock gene

Mice are nocturnal. When both wild type and Chrono knockout mice are kept in an environment with 12 hours of light (blue) and 12 hours of dark (white).They align their...
Over the last few decades researchers have characterized a set of clock genes that drive daily rhythms of physiology and behavior in all types of species, from flies to humans. Over 15 mammalian clock proteins have been identified, but researchers surmise there are more. A team from the Perelman School of Medicine at the University of Pennsylvania wondered if big-data approaches could find them.

Study to examine welfare aspects of cat containment
The first study of its kind will assess the impact that electronic containment systems may have on cat welfare. Biology News, Wed, 23 Apr 2014 11:05:58 GMT

Personality determines whether tarantulas copulate with males or cannibalize them
Sexual cannibalism in spiders – the attack and consumption of males by females before or after copulation – is very widespread. A new investigation analyses the reason behind such extreme behaviour, at times even before the females have ensured the sperm's fertilisation of their eggs.

Spying on plant communication with tiny bugs
Internal communications in plants share striking similarities with those in animals, new research reveals. With the help of tiny insects, scientists were able to tap into this communication system. Their results reveal the importance of these communications in enabling plants to protect themselves from attack by insect pests. Biology News, Wed, 23 Apr 2014 11:05:58 GMT
