A new diagnostic technique which may greatly simplify the detection of Alzheimer’s disease has been discovered. There is currently no accepted blood test for Alzheimer’s, and the diagnosis is usually based on expensive and labor-intensive neurological, neuropsychological and neuroimaging evaluations.

Scientists have created a “hybrid” system to examine real-time interactions between humans and machines (virtual partners). By pitting human against machine, they open up the possibility of exploring and understanding a wide variety of interactions between minds and machines, and establishing the first step toward a much friendlier union of man and machine, and perhaps [...]

Treating children with inflammatory bowel disease (IBD) usually involves the same steroids-based medication prescribed to adults. But such treatments can have negative side effects for kids and teens dealing with IBD. A researcher now promotes liquid nutrition to combat inflammatory bowel disease.

Three-dimensional, real-time X-ray images may be closer to reality. New work on a process called high-harmonic generation, or HHG. X-ray radiation can be created by focusing an optical laser into atoms of gaseous elements – usually low-electron types such as hydrogen, helium, or neon.

A new theory on the role of developmental experiences has been described. Maternal perception of a threatening environment may be transmitted to the fetus when hormones cross the placenta and affect fetal physiology, effectively ‘programming’ the fetal stress response system and associated behaviors toward enhanced vigilance.

Same-sex behavior is a nearly universal phenomenon in the animal kingdom, common across species, from worms to frogs to birds, concludes a new review of existing research.

Partially hydrogenated vegetable oils in processed foods contain trans fatty acids that interfere with the regulation of blood flow. A new report reveals a new way in which these “trans fats” gum up the cellular machinery that keeps blood moving through arteries and veins.

Rushing to salvage fossils from the Panama Canal earthworks, a paleontology intern unearthed a set of fossil teeth. Experts identified the fossil as Anchitherium clarencei, a three-toed browsing horse.

Gene regulatory networks in cell nuclei are similar to cloud computing networks, such as Google or Yahoo!, researchers report in the journal Molecular Systems Biology. The similarity is that each system keeps working despite the failure of individual components, whether they are master genes or computer processors.
