Junk food and poor oral health increase risk of premature heart disease
The association between poor oral health and increased risk of cardiovascular disease should make the reduction of sugars such as those contained in junk food, particularly fizzy drinks, an important health policy target, say experts writing in the Journal of the Royal Society of Medicine.

Methylation signaling controls angiogenesis and cancer growth
A study led by researchers at Boston University School of Medicine demonstrates a new mechanism involving a signaling protein and its receptor that may block the formation of new blood vessels and cancer growth.

Crossing continents -- where we drive affects how we drive
For the first time a team of experts have been looking at the cross-cultural effect on drivers' hazard perception and their research has shown that compared to British drivers, Malaysian motorists are less likely to identify situations as dangerous and also react to them later.

How a legless, leaping fish that lives on land avoids predators
One of the world's strangest animals -- a legless, leaping fish that lives on land -- uses camouflage to avoid attacks by predators such as birds, lizards and crabs, new research shows.

Telescope to track space junk using youth radio station
A combination of pop songs, talkback radio and cutting-edge science has enabled Australian astronomers to identify a way to prevent catastrophic, multi-billion dollar space junk collisions, a new study has revealed.

Scientists stitch up photosynthetic megacomplex
In Science scientists at Washington University in St. Louis report on a new technique that allowed them to extract a photosynthetic megacomplex consisting of light antenna and two reaction centers from the membrane of a cynaobacterium.

Bone grafting improvements with the help of sea coral
Sea coral could soon be used more extensively in bone grafting procedures thanks to new research that has refined the material's properties and made it more compatible with natural bone.

Virtual electromobility in Munich
