It has all the hallmarks of a Cretaceous melodrama. A dinosaur sits on her nest of a dozen eggs on a sandy river beach. Water levels rise, and the mother is faced with a dilemma: Stay or abandon her unhatched offspring to the flood and scramble to safety?

After studying the sleep characteristics of nearly 11,000 adults in an overnight sleep laboratory, researchers suggest that obstructive sleep apnea — and, in particular, the low nighttime oxygen saturation of the blood it causes — may be a risk factor for sudden cardiac death.

Scientists may have overcome a major hurdle to calculating how much carbon dioxide is absorbed and released by plants, vital information for determining the amount of carbon that can be safely emitted by human activities. The problem is that ecosystems simultaneously take up and release CO2. The key finding is that the compound carbonyl sulfide, [...]
Researchers have discovered an essential mechanism for the maintenance of the normal structure of myelin, the protective covering that insulates and supports nerve cells (neurons).

A shipping company must exercise patience whenever it needs a new a ship’s propeller: its production is time consuming because a foundry workers must first fashion a model and a mold based on it. Industrial robots will support them in the future.
Optimizing nutrition with the addition of supplements, such as powder drinks and multivitamin tablets formulated for massive weight loss patients, is vital to successful body contouring surgery, according to new research.

Researchers have shown a new mechanism for how human consumption of red meat and milk products could contribute to the increased risk of cancerous tumors. Their findings suggest that inflammation resulting from a molecule introduced through consumption of these foods could promote tumor growth.

The only known genetic risk factor for Alzheimer’s disease slows down the brain’s ability to export a toxic protein known as amyloid-beta that is central to the damage the disease causes, scientists have found. The research provides new clues into the workings of a protein known as apolipoprotein E4, or ApoE4, which increases the risk [...]

Extremely small nanoscale particles are released by common kitchen appliances in abundant amounts, greatly outnumbering the previously detected, larger-size nanoparticles emitted by these appliances, according to new findings by NIST researchers.

For the first time researchers have shown that a commonly used anesthetic can produce changes associated with Alzheimer’s disease in the brains of living mammals, confirming previous laboratory studies. Scientists have shown how administration of the gas isoflurane can lead to generation of the toxic amyloid-beta protein in the brains of mice.
