The original NASA/ESA Hubble Space Telescope image of the famous Pillars of Creation - in the Eagle Nebula, Messier 16 - was taken two decades ago and immediately became its most famous picture. Since then, these billowing clouds, which extend over a few light-years, have awed the public. 

One of the concerns about the switch from incandescent to fluorescent lighting was that while the ballasts are higher frequency now - humans do not have to hear that annoying hum - they were right in the range that pets still hear.

Interventional treatments such as surgery provide good functional outcomes and a high cure rate for patients with lower-grade arteriovenous malformations (AVMs) of the brain, according to a new study. These findings contrast with a recent trial reporting better outcomes without surgery or other interventions for AVMs.

A study in Science has tied the aging process to the deterioration of tightly packaged bundles of cellular DNA known as heterochromatinand say that the genetic mutations underlying Werner syndrome, a disorder that leads to premature aging and death, results in the deterioration of these bundles.

The discovery used stem cell and gene-editing technologies and could lead to ways of countering age-related physiological declines by preventing or reversing damage to heterochromatin.

Researchers have shown that, like humans, mustached bats use the left and right sides of their brains to process different aspects of sounds.

No other animal, not even monkeys or apes, has proved to use such hemispheric specialization for sound processing - meaning that the left brain is better at processing fast sounds, and the right processing slow ones. 

"These findings upset the notion that only humans use different sides of their brains to distinguish different aspects of sound," says the study's senior author, Stuart Washington, PhD, a neuroscientist at Georgetown.

Washington says the findings of asymmetrical sound processing in both human and bat brains make evolutionary sense.

Individuals with Type 2 Diabetes have difficulty regulating their glucose - blood sugar - levels, particularly after meals but a new study has found that Type 2 diabetics can eat more protein at breakfast to help reduce glucose spikes at both breakfast and lunch.

Researchers monitored Type 2 diabetics' levels of glucose, insulin and several gut hormones -- which help regulate the insulin response -- after breakfast and lunch. The participants ate either high-protein or high-carbohydrate breakfasts, and the lunch included a standard amount of protein and carbohydrates.
