In a first, Einstein scientists discover the dynamics of transcription in living mammalian cells

...at a Sunday driver on a narrow road slows down all traffic behind him. But in the absence of pausing, elongation proceeded much faster about 70 nucleotides synthesized per second than has previously been reported. These two phenomena pausing and rapid RNA synthesis during elongation may be crucial for ...

Scientists take next step in understanding potential target for ovarian cancer treatment

A traffic cop protein in the cell may have an even more impo... It activates km23 into action. km23 acts like a traffic cop for specific proteins as they move in the cell on a highway called a microtubule. It is responsi...

...rfect circles for hours, perhaps similar to rotary traffic during a Boston rush hour. Laser ablation of amphid sensory neurons, particularly ASJ or ASH, disrupted this electrosensory behavior. These neurons were sensitive to the direction and strength of electric fields as measured by calcium imaging of immo...

New approach to pulmonary hypertension shows promise

...ertension. "You can think of NFAT as a rogue air traffic controller that keeps planes in the air that need to land or sends them to the wrong destinations and causes them to attack places they shouldn't," explained Michelakis, the Canada Research Chair in Pulmonary Hypertension.

Bigger is smarter

...ing data indicate that some correction for 'neural traffic maintenance' is probably needed. If it wasn't needed, then we would be stuck with some real puzzles, such as the fact that there are no consistent sex differences in IQ, yet men generally have larger brains. And, of course, elephants and whales posse...

Dinosaur hearing, listening to muscle noise, quieter cubicles

... River. Details of acoustic noise produced by ship traffic will be presented by Heui-Seol Roh. The measurements may provide a basis for developing systems that can detect underwater threats. Brian Borowsky will present an estimation of the distances at which threats can be detected (2pEA6; contact Alexande...

News tips from the Journal of Neuroscience

...irginia M.-Y. Lee This week, Roy et al. monitored traffic in the fast and slow lanes of axons. Proteins are transported to distal axons in three distinct groups: fast component (FC), slow component-a (SCa), and slow component-b (SCb). The well described FC and SCa mechanisms move vesicular and structural ca...

Transport interrupted -- Texas A&M biologists trace cause of early blindness to tissue defect

...otein-1 (REP1), which helps regulate intracellular traffic in the photoreceptors as well as a neighboring tissue called the retinal pigment epithelium (RPE). In collaboration with the University of Western Kentuckys Joseph Bilotta, they observed that mutations in REP1 disrupt cellular processes in the RPE, c...

...ght flourishes in niche markets, such as brake and traffic lights, and future conquests are in sight. Efficiencies of 138 lm/W have been achieved in the lab (but not yet in commercial devices) for low power devices and over 90 lm/W for high power devices. According to George Craford (Philips Lumileds Lighti...

Diesel exposure model reduces allergy risk assessment errors

Researchers found that infants who were exposed to the highest levels of elemental carbona marker of diesel exposurewer...

Motor protein plays key role in connecting neurons

...t, a sort of two-way highway in the cell's highest traffic area, says Dr. Wen-Cheng Xiong, developmental neurobiologist at the Medical College of Georgia. Part of its cargo is DCC receptor which needs to move from the central nucleus where it's synthesized to the cell's periphery, Dr. Xiong and her colleag...

Rural America more prepared for disaster -- also more vulnerable

Most CERTS take an all-hazards approach -- that is, they practice responding to a range of potential emergencies. Many o...

UCR researchers examine how some invasive plants gain a foothold
