Mention biocontrol and people think of the cane toad catastrophe. But a sap-sucking bug could be the only way to win the war against the world's worst weed (full text available to subscribers)

Thanks, great great great great great great great great great great great great grandad RESEARCHERS have known for a while that many people alive today carry genes from human species other than Homo sapiens--the result o...

Ancient Japanese gold leaf artists were truly masters of their craft. An analysis of six ancient Namban paper screens show that these artifacts are gilded with gold leaf that was hand-beaten to the nanometer scale. Study...

Like a line of falling dominos, a cascade of molecular events in the bone marrow produces high levels of inflammation that disrupt normal blood formation and lead to potentially deadly disorders including leukemia, a res...

Anecdotal information on patients with both Alzheimer's disease and cerebrovascular disease have been confirmed by researchers using mouse models in two different studies. The findings, which found elevated levels of hom...

A breakthrough discovery into how living cells process and respond to chemical information could help advance the development of treatments for a large number of cancers and other cellular disorders that have been resist...

Scientists have discovered a new way by which metabolism is linked to the regulation of DNA, the basis of our genetic code. The findings may have important implications for the understanding of many common diseases, incl...

Researchers have discovered that an enzyme involved in intracellular signaling plays a crucial role in developing metabolic syndrome, a finding that has a spinoff company developing a drug to potentially treat the condit...

Researchers have developed an economical, reliable and heavy metal-free chemical reaction that yields fully functional 1,2,3-triazoles. Triazoles are chemical compounds that can be used as building blocks for more comple...

A third of the global population is infected with the bacterial pathogen that causes tuberculosis. Most carriers control the infection and are asymptomatic, but severe forms of the disease kill over a million people ever...

Participants between the ages of 11 and 36 received either the two drugs or a placebo while continuing their insulin injections. The group receiving the drugs did not experience an improvement in insulin production, but ...

Intimate partner violence is a significant health issue faced by women veterans, but little has been known up until now about their preferences for IPV-related care. A new study has found that most of these women support...

A hotpot with chicken is one of the primary risk factors for a campylobacter infection in Switzerland in winter, a new study shows. At the end of each year, the reported case numbers of this severe intestinal infection i...

Using exquisitely detailed maps of molecular shapes and the electrical charges surrounding them, researchers have discovered how the metal beryllium triggers a deadly immune response in the lungs. They show how a genetic...

Reproductive biologists have ruled out the 'Production-Line Hypothesis,' one of the leading thoughts on why older women have an increased risk of miscarriages and children with birth defects.

Understanding the basis of psychiatric disorders has been extremely challenging because there are many genetic variants that may increase risk but are insufficient to cause disease. Now investigators describe a strategy ...

Up to one-quarter of individuals currently labeled as obese are actually metabolically healthy. Though obesity is a major risk factor for diabetes, the two conditions aren't always linked. A new study sheds light on a po...

It has been known for its flavorful addition to soups and as a delicacy for dogs but bone marrow fat may also have untapped health benefits, new research finds. Researchers find that with calorie restriction, a less-stud...

A new study finds a modification to the transcriptional protein MEF2 that inhibits the growth of new brain cells and survival of existing cells. The findings show promise for therapeutic intervention for a variety of neu...

New research helps explain the heat-generating properties of brown fat, a possible key to weight loss.

A new study updates the number of human genes to 19,000; 1,700 fewer than the genes in the most recent annotation, and well below the initial estimations of 100,000 genes. The work concludes that almost all of these gene...

Every organism has one aim: to survive. Its body cells all work in concert to keep it alive. They do so through finely tuned means of communication. Scientists have now successfully revealed for the first time the laws b...
