Global seed vault marks 1-year anniversary

Four tons of seeds - almost 90,000 samples of hundreds of crop species - were delivered today to the Svalbard Global Seed Vault as it celebrated its one-year anniversary.

Impact of fat on cancer spread

Researchers have precisely measured the impact of a high-fat diet on the spread of cancer, finding that excessive dietary fat caused a 300 percent increase in metastasising tumour cells in laboratory animals.

World's smallest periscopes

A team of Vanderbilt scientists have invented the world's smallest version of the periscope and are using it to look at cells and other micro-organisms from several sides at once.

Differentiating colorectal polyps

Researchers compared narrow-band imaging (NBI) without high magnification to standard white light colonoscopy in differentiating colorectal polyps during real-time colonoscopy.

When pain hurts more

Researchers at Harvard University have discovered that our experience of pain depends on whether we think someone caused the pain intentionally.

Opportunities in nutrigenomics

A new study uncovers 11 gene variants associated with three blood lipids measured to determine cardiovascular disease risk: low-density lipoprotein cholesterol, high-density lipoprotein and triglycerides.

Tool analyses cancer and Facebook

Researchers have devised a new research tool that could help unpick the complex cell interactions that lead to cancer and also allow social scientists to mine Facebook for useful insights.

Uncovering keys to DNA methylation

Researchers have shed more light on the mechanism that regulates DNA methylation, a fundamental biological process in which a methyl group is attached to DNA.

In defense of the egg

A study recently published online estimates that eating one egg per day is responsible for less than 1 percent of the risk of coronary heart disease in healthy adults. Lifestyle factors played a more significant role.

Enlisting pigs and dogs for therapies

Human and veterinary medicine could receive a big boost through use of larger animals, especially pigs and dogs, in research, with Europe at the forefront.

Potent treatment for fungal infections

The effectiveness of voriconazole in combating fungal infections has been confirmed by a new study. The research reinforces earlier findings that this drug is a potent antifungal drug.

Old and young brains rely on different systems

Neuroscientists have discovered that older people use their brains differently than younger people when it comes to storing memories, particularly those associated with negative emotions.

Revisiting male bisexuality

Sex researchers are reflecting on studies involving male bisexuality since the "Kinsey Report" and potential directions for future research.

The pathway to mixed-lineage leukaemia

A researcher recently found that in cancer cells the MLL-AF4 protein binds to at least 169 genes, many of which are overexpressed in leukaemia cells and encode hematopoietic stem cell regulators.

Single virus used to convert adult cells

Whitehead Institute researchers have greatly simplified the creation of so-called induced pluripotent stem cells, cutting the number of viruses used in the reprogramming process from four to one.

Solving a failed vaccine mystery

Scientists have figured out why a respiratory syncytial virus vaccine used in 1966 to inoculate children against the infection instead caused severe respiratory disease.

Egg donation mostly satisfactory

Two-thirds of women who donated eggs to fertility clinics reported satisfaction with the process, but 16 percent complained of subsequent physical symptoms and 20 percent reported lasting psychological effects.

Sex difference linked to brain structure

A recent study shows a connection between this sex-linked ability and the structure of the parietal lobe, the brain region that controls this type of skill.

Lean muscle mass battles cancer

A study provides evidence that varying body compositions of cancer patients likely plays a role in survival rates, activity levels during the illness and potentially, even the reaction to chemotherapy treatment.
