A synthetic nasal formulation of the hormone oxytocin reduced caloric intake in healthy men, particularly consumption of fatty foods, after a single treatment, a new study finds. The results, to be presented Sunday at The Endocrine Society's 97th annual meeting in San Diego, confirm those of animal studies showing oxytocin reduces food intake.

Oxytocin nasal spray reportedly lowered the number of calories men consumed at a subsequent breakfast whether they were normal weight or overweight. In addition, the researchers found that oxytocin improved metabolic measures, such as insulin sensitivity, which is the body's ability to successfully clear glucose (sugar) from the bloodstream.

Medical marijuana is proliferating across the country due to the ability of cannabis ingestion to treat important clinical problems such as chronic pain. However, negative side effects and the development of tolerance limit the widespread therapeutic use of Δ9-tetrahydrocannabinol (Δ9-THC), the major psychoactive ingredient in cannabis.

THC's side effects are produced via its actions at cannabinoid CB1 receptors in the brain. Thus, scientists theorized that an agent with similar mechanistic actions, but that activate CB2 receptors instead, may eliminate the unwanted side effects while maintaining an equivalent level of efficacy.

Though 23andMe finally got FDA approval for a test, that is much different than the unvalidated claims about 250 conditions that they used to make. They got a cease and desist letter from the FDA because of their high profile.

Soybean oil accounts for more than 90 percent of all the seed oil production in the United States and genetically modified (GM) soybean oil, obviously made from seeds of GM soybean plants, was recently introduced into the food supply with the benefit that it is healthier than conventional soybean oil.

Is it true?

When a young, wingless praying mantis jumps,  from take-off to landing is a mere tenth of second--literally faster than the blink of a human eye. During a jump, the insect's body rotates in mid-air at a rate of about 2.5 times per second.

And yet, the jumps are precise.

When mantises jump, they land on target every time. 

"This is akin to asking an ice skater who is rotating at the same speed as these mantises to stop suddenly and accurately to face a specific direction," says Malcolm Burrows of the University of Cambridge.

Women are not under-represented in science, they dominate in some fields and lag in others, part of the natural variation in humanity - but in academia at the highest levels, they are under-represented.
