Self-healing materials can repair themselves by restoring their initial molecular structure after the damage and scientists from Evonik Industries
and the Karlsruhe Institute of Technology have developed a chemical crosslinking reaction that ensures good short-term healing properties of the material under mild heating.   

Researchers recently used an array of high-speed video cameras operating at 7,500 frames a second to capture the wing and body motion of Drosophila hydei
after they encountered an image of an approaching predator. 

The fruit flies are about the size of a sesame seed and rely on a fast visual system to detect approaching predators. And scientists found out that even Top Gun pilots might be envious of the screaming-fast banked turns and slick moves the flies employed. In the midst of a banked turn, the flies can roll on their sides 90 degrees or more, almost flying upside down at times.

In 2017, the British will introduce a new coin that should be difficult to counterfeit. 

The last time a Queen Elizabeth sat on the throne they tried the same thing, to deter “divers evil persons” from damaging the reputation of English coinage and, with it, the good name of the nation. And they tried it plenty of times since. And before.

As long as there has been money, there has been counterfeiting. Today, the Royal Mint estimates retailers lose about $25 million a year due to counterfeits and up to 3% of their £1 coins are fake.

How is nitrogen removed from the ocean? Some new findings may provide answers.

The debate centers on how nitrogen, one of the most important food sources for ocean life and a controller of atmospheric carbon dioxide, becomes converted to a form that can exit the ocean and return to the atmosphere where it is reused in the global nitrogen cycle. 

Researchers have argued over which of two nitrogen-removal mechanisms, denitrification and anammox, is most important in the oceans. The question is not just a scientific curiosity, but has real world applications because one mechanism contributes more greenhouse gases to the atmosphere than the other.

Apoptosis is used by cells that are changed by disease or are simply not needed any longer to eliminate themselves before they become a hazard to the body—on a cellular level, death is part of life. Disruption of this process can lead to cancer or immunodeficiencies, but also to autoimmune diseases, in which cells attack their own body.

London, UK, Saturday 12 April 2014: A UK study[i] investigating the link between low vitamin D status and non-alcoholic fatty liver disease (NAFLD) in British children has identified a genetic variant associated with the disease's severity.

The research, conducted by the King's College Hospital Paediatric Liver Centre and the University of Surrey's School of Biosciences and Medicine, and funded by the Children's Liver Disease Foundation retrospectively analysed the medical records of 120 paediatric patients with NAFLD.
