New technology targets cancers

Breast-specific gamma imaging (BSGI) is effective in the detection of cancers not found on mammograms or by clinical exam, according to a study.

Counting genetic messages

Scientists have described a technique for looking more precisely at a fundamental step of a cell's life - a gene, DNA, being read into a message, mRNA.

Benefits of replacing corn with perennial grasses

Converting forests or fields to biofuel crops can increase or decrease greenhouse gas emissions, depending on where - and which - biofuel crops are used.

Nanotech culture war possible

Rather than infer that nanotechnology is safe, members of the public who learn about this novel science tend to become sharply polarised along cultural lines, according to a study.

Strained quantum dots show new optical properties

Quantum dots, tiny luminescent particles made of semiconductors, hold promise for detecting and treating cancer earlier.

Quantum networks advance

Physicists have taken a significant step toward creation of quantum networks by establishing a new record for the length of time that quantum information can be stored in and retrieved from an ensemble of very cold atoms.

Food affects cells like hormones

A team of researchers have discovered an important new mechanism with which cells can detect nutrients.

Dinosaurs were airheads

By using CT scans, the scientists were able to develop 3-D images of the dinosaur skulls that show a clearer picture of the physiology of the airways.

Faster genetic diagnosis for hereditary diseases

Researchers connected to the University of Antwerp have developed a new method that enables them to track down the cause of hereditary diseases more quickly and efficiently.

Reversing early-stage kidney disease

Researchers at the University of Warwick have discovered high doses of thiamine - vitamin B1 - can reverse the onset of early diabetic kidney disease.

Potential Alzheimer's treatment

A drug commonly used to treat epilepsy could help clear the plaques in the brain associated with Alzheimer's disease, according to researchers at the University of Leeds.

Malaria vaccine candidate advancing in Africa

A recent study revealed that the world's most clinically advanced malaria vaccine candidate provides both infants and young children with significant protection against malaria.

Understanding Gleevec-type drugs

Researchers are closer to understanding why certain chronic myeloid leukaemia mutations are not stopped by the revolutionary targeted cancer pill, Gleevec, or similar therapies in that drug family.

Men Are Red, Women Are Green

Researchers discovered a colour difference in an analysis of dozens of faces. They determined that men tend to have more reddish skin and greenish skin is more common for women.

Preventing high risk-bladder cancer

A study suggests that selenium, a trace mineral found in grains, nuts and meats, may aid in the prevention of high-risk bladder cancer.

Managing cholesterol and glucose levels

Scientists have identified 12 new genes that are somewhat strange bedfellows: Some link gallstones and blood cholesterol levels, others link melatonin and sleep patterns to small increases in glucose levels and larger jumps in the risk of diabetes.

UK and US positive towards nanotech

The results of a new U.K.-U.S. study show that ordinary people in both countries hold very positive views of nanotechnologies.

Genetic underpinnings of nicotine addiction

Research shows that smokers who carry a particular version of a gene may suffer from concentration problems and other cognitive deficits when abstaining from nicotine.

Genetics of alcohol response

Researchers have identified a region on the human genome that appears to determine how strongly drinkers feel the effects of alcohol and thus how prone they are to alcohol abuse.

Poor Sleep linked to postpartum depression

Research shows that depression symptoms worsen in PPD patients when their quality of sleep declines. Sleep deprivation can hamper a mother's ability to care for her infant.
