Accelerated snowmelt -- precipitated by desert dust blowing into the mountains -- changes how alpine plants respond to seasonal climate cues that regulate their life cycles, according to a new study. These results indicate that global warming may have a greater influence on plants' annual growth cycles than previously thought.

Scientists have found that by switching the social role of honey bees, aging honey bees can keep their learning ability intact or even improve it. The research team is hoping to use them as a model to study general aging processes in the brain and how to prevent or ameliorate cognitive impairments associated with old age.

Scientists have shed light on the processes that lead to certain human DNA mutations that are implicated in hundreds of inherited diseases. The results one day could influence the way couples who seek to have children receive genetic counseling.

Researchers have managed to make out the "self-irrigating" mechanism of the desert rhubarb, which enables it to harvest 16 times the amount of water than otherwise expected for a plant in this region based on the quantities of rain in the desert. This is the first example of a self-irrigating desert plant, the scientists say.

It's a frequent scene in television crime dramas: Clever police technicians zoom in on a security camera video to read a license plate or capture the face of a hold-up artist. But in real life, enhancing this low-quality video to focus in on important clues hasn't been an easy task. Until now. Researchers in Israel have developed a new video "perfection tool" to help investigators enhance raw video images and identify suspects.

A novel method to seal leaking heart valves was shown to be safe in its first use in heart failure patients. If effective in larger trials, the PTMA system could significantly reduce the life-threatening risks associated with surgical repair of the mitral valve.

Researchers are using a combination of light and ultrasound to visualize fluorescent proteins that are seated several centimeters deep into living tissue.

For a long time, batteries were bulky and heavy. Now, a new cutting-edge battery is revolutionizing the field. It is thinner than a millimeter, lighter than a gram, and can be produced cost-effectively through a printing process.

A mother's weight and the amount she gains during pregnancy both impact her daughter's risk of obesity decades later, according to a new study.

Researchers have discovered a technique to safely handle and transport white phosphorous.
