Scientists study freezing process at the ultra-small scale

Using what is thought to be the world's smallest pipette, two researchers at the U.S. Department of Energy's Brookhaven National Laboratory have shown that tiny droplets of liquid metal freeze much differently than their larger counterparts.

Scientists discover key player in embryonic muscle development

Muscle fibers are large cells that contain many nuclei. They begin, like all animal cells, as naive embryonic cells. These cells differentiate, producing intermediate cells called myoblasts that are now destined to become muscle.

Breakthrough in photoswitchable fluorescent protein science

University of Oregon scientists have identified molecular features that determine the light-emitting ability green fluorescent proteins, and by strategically inserting a single oxygen atom they were able to keep the lights turned off for up to 65 hours.

Scientists take a close look at early events in immune response

A Sandia National Laboratories research team led by Anup Singh is taking a new approach to studying how immune cells respond to pathogens in the first few minutes and hours of exposure.

New screening method for cervical cancer holds promise

A method of screening women in Ghana for early signs of cervical cancer and providing preventive treatment at the same visit appears to be safe, acceptable to women and feasible, according to a study by a researcher at the Stanford University School of Medicine.

Glimpse into early brain development shows how nerve cells move into position

Tucked into the lower, rear portion of the brain, the cerebellum plays key roles in motor learning, motor memory and sensory perception. It's also where the majority of metastatic childhood brain tumors are located. Yet scientists still know very little about its early growth.

Researchers uncover genetic sequence responsible for rare form of pancreatic cancer

Pancreatic ductal adenocarcinoma is an almost uniformly fatal disease regardless of the stage at time of diagnosis. However, a small percentage of patients develop a form of ductal adenocarcinoma associated with cystic lesions that can be detected earlier, is less aggressive and has a 50 percent long-term survival rate.

Researchers discover a new mechanism that regulates stem cell division

Errors in stem cell division can give rise to tumours. By studying stem cells in the fruit fly, scientists at the Institute for Research in Biomedicine (IRB Barcelona) have identified one of the mechanisms that govern how these cells divide.
