The world's largest species of monkey "chooses" mates with genes that are different from their own to guarantee healthy and strong offspring, according to a new research study.

Soy component may be key to fighting colon cancer

Scientists have identified a new class of therapeutic agents found naturally in soy that can prevent and possibly treat colon cancer, the third most deadly form of cancer. Sphingadienes are natural lipid molecules found in soy that research shows may be the key to fighting colon cancer.

Atomic-level snapshot catches protein motor in action

The atomic-level action of a remarkable class of ring-shaped protein motors has been uncovered using a state-of-the-art protein crystallography beamline at the Advanced Light Source. These protein motors play pivotal roles in gene expression and replication, and are vital to the survival of all biological cells, as well as infectious agents, such as the huma […]

Eye floaters and flashes of light linked to retinal tear, detachment

Suddenly seeing floaters or flashes of light may indicate a serious eye problem that -- if untreated -- could lead to blindness, a new study shows.

Exposures to metals and diesel emissions in air linked to respiratory symptoms in children

Exposure shortly after birth to ambient metals from residential heating oil combustion and particles from diesel emissions are associated with respiratory symptoms in young inner city children, according to a new study. The study is the first to analyze the effects of exposure to airborne metals in this very young population and the findings could have impor […]

America's increasing food waste is laying waste to the environment

Food waste contributes to excess consumption of freshwater and fossil fuels which, along with methane and carbon dioxide emissions from decomposing food, impacts global climate change. Scientists have calculated the energy content of nationwide food waste from the difference between the US food supply and the food eaten by the population.

First black holes may have incubated in giant, starlike cocoons

The first large black holes in the universe likely formed and grew deep inside gigantic, starlike cocoons that smothered their powerful X-ray radiation and prevented surrounding gases from being blown away, says a new study.

How coughing is triggered by environmental irritants

Scientists have revealed how environmental irritants such as air pollution and cigarette smoke cause people to cough. The authors of a new study have identified the reaction inside the lungs that can trigger coughing when a person is exposed to particular irritants in the air. They suggest that their findings may ultimately lead to the development of new tre […]

Meiosis: Chromosomes Dance And Pair Up On The Nuclear Membrane

Meiosis -- the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell -- is a major crossroads in all organisms reproducing sexually. Yet, how the cell precisely choreographs these chromosomal interactions is a long-standing question. New findings show that the cell's cytoskeleton, which moves things around i […]

Sticky solution for identifying effective probiotics

Scientists have crystallized a protein that may help gut bacteria bind to the gastrointestinal tract. The protein could be used by probiotic producers to identify strains that are likely to be of real benefit to people.
