Nano-Probes Allow an Inside Look at Cell Nuclei

...chanism, a ploy that gives the virus an unhindered ride inside the nucleus. Chen and Gerion obtained a portion of this protein and attached it to the quantum dot. The result is a hybrid quantum dot, part biological molecule and part nano-sized semiconductor, that is small enough to slide through the nucle...

Artifical cornea lets woman blind 20 years see

...sue. "Getting an artificial cornea is not an easy ride for the patient," Afshari warns. "We carefully screen each candidate and educate them about the lifetime commitment involved with the keratoprosthesis. Patients require a lot of follow up to make certain the artificial cornea remains structurally sou...

Grizzlies set to invade high Arctic?

...land grizzly bear from the air during a helicopter ride to a geology research site in 2003. He photographed mid-distance shots of the large bear with characteristic grizzly features including a prominent shoulder hump, dark brown hair on and around the rear legs, and faded (grizzled) hair on the rest of t...

Researchers make surprise discovery that some neurons can transmit three signals at once

...om a cell, neurotransmitters are sent on a one-way ride that dead ends at the membrane of the adjacent cell. Like lock and key, they bind to specific receptors on the surface of the receiving cell, causing its electrical activity to be enhanced or inhibited. The first week after birth marks a critical ph...

Study shows how retinoic acid enters a cell's nucleus

...to rapidly enter a cell's nucleus, it must catch a ride on a water-soluble protein called cellular retinoic acid-binding protein type II (CRABP-II). This protein was discovered over two decades ago, but until recently scientists had no idea what it did. Much like a doorway that requires a pass code to en...

York scientists warn of dramatic impact of climate change on Africa

...it looks like Africa is going to be in for a rough ride over the next few decades," Dr Lovett said. ...

HIV accessory protein disables host immunity via receptor-protein intermediary

...through the glucocorticoid receptor. Vpr hitches a ride on the glucocorticoid receptor, driving glucocorticoid to bind to PARP-1?which, in turn, inactivates it. "Ultimately, glucocorticoid is really an intermediary between Vpr and PARP-1," explains Weiner. Weiner cites several potential clinical implicat...

APS lecturer shows rare video of 'teacher-student' immune cell interactions in live animal

...the target T cells patrol the body by hitching a ride in the blood, methodically stopping at each lymph node like a night security guard making the rounds and checking the doors. There are dendritic cells in the lymph nodes, waiting to present antigens in a way the T cells can recognize. Each T cell re...

Speeding discovery of the 'human cancer genome'

...rds, they are genes that simply came along for the ride with those that actually contribute to the cancerous cells' ability for unchecked proliferation or spread. Simply sorting through those differences one by one takes time and money, said Lynda Chin of the Dana-Farber Cancer Institute and Harvard Me...

Edge density key to controlling gypsy moth spread

...daries. External colonies occur when moths hitch a ride on vehicles or other items relocated by people. Without an Allee effect, these colonies would establish, but because gypsy moths exhibit an Allee effect, the low populations are insufficient for establishment of permanent populations. This is als...

Ocean seep mollusks may share evolutionary history with other deep-sea creatures

...ies outside of the cold seeps have also managed to ride out these changes. "The shallow water environment is much more challenging, subject to changes in sea levels, extinction events, pollution, sediment runoff--all sorts of factors which don't affect animals in the deep sea," Little explained. This m...

Synthetic peptide targets latent papilloma virus infections

Caribbean frogs started with a single, ancient voyage on a raft from South America

...y colonized the Caribbean islands likely hitched a ride on floating mats of vegetation called flotsam, which is the method typically used by land animals to travel across salt water. "Some rafts of flotsam, if they are washed out of rivers during storms and caught in ocean currents, can be more than a mi...
