How Animals Offer Clues to Regeneration | 2/15/2013Exploring the strategies that some organisms use to regrow missing cells, organs and appendages might help researchers find ways to regenerate lost or injured body parts.
Remarkable RNAs | 1/8/2013RNA is a versatile molecule that is involved in many essential cellular functions. Here’s a quick rundown of types of RNA that scientists are discovering and learning more about.
Tick Tock: New Clues About Biological Clocks and Health | 11/1/2012Read about genes and proteins that run biological clocks and help keep daily rhythms in synch.
Learning About Human Biology From a Fish | 10/15/2012Learn why this small fish is a big friend to scientists—and how it’s offering important insights into our own biology.
Once Upon a Stem Cell | 7/18/2012Learn about some of the substantial strides that researchers have made in understanding different stem cell characters and their fates.
Genetics by the Numbers | 6/12/2012Get stats on what scientists have learned so far about genetics
Five Ways Your Cells Deal With Stress | 5/17/2012Find out how cells respond to rising temperatures, toxins, infections, resource shortages and other stressors.
Armpits, Belly Buttons and Chronic Wounds: The ABCs of Our Body Bacteria | 4/26/2012Understanding how and why bacteria colonize particular places on the body could point to ways of treating skin and other conditions.
Chromosomal Caps Count Down to Cell Death—Or Cancer | 2/23/2012Every cell in your body has a clock called a telomere that ticks down the number of times it can safely divide. If scientists could make drugs to control telomeres, they could perhaps treat diseases of aging as well as cancer.
Drakes: A Mythological Model Organism | 11/16/2011With the aid of Web-based programs that use dragons, high school students are learning about complex genetic concepts and gaining an appreciation for how science is done—all while having fun.
Everyday Evolution | 10/6/2011When you head out to get your annual flu shot, you might be thinking about the brief prick of pain or possible side effects. But are you thinking about evolution? After all, it's why you're getting jabbed.
One More Way Plants Help Human Health | 7/13/2011This is the latest in a long line of research, much of it supported by the National Institutes of Health, that uses plants to solve puzzles in human health.
Living Laboratories: How Model Organisms Advance Science | 6/1/2011Think you don't have much in common with slime molds and mustard plants? Think again. Research using model organisms like these continues to lead to new ways to maintain health and diagnose and treat disease.
The Rhythms of Life | 3/8/2011A system of biological clocks controls the daily, or circadian, rhythms of the body. These roughly 24-hour cycles of physical, mental and behavioral changes are found in humans and fruit flies, plants and even tiny microbes.
Cellular Suicide: An Essential Part of Life | 2/23/2011Apoptosis, sometimes called "cellular suicide," is a normal, programmed process of cellular self-destruction. Even though it involves cell death, apoptosis serves a healthy and protective role in our bodies.
Learning From Bacterial Chatter | 1/12/2011What do digestion, cholera and tooth plaque have in common? They're all made possible by quorum sensing, a form of bacterial communication.
