Researchers probe health and safety impacts of nanotechnology

...or the type of cells she has tested, the cells can readily absorb the aluminum nanoparticles, and there is a correlation between size, shape and toxicity. That said, Palazuelos stressed that it is far too early to conclude that aluminum nanoparticles are harmful to human health. Epidemiological studies evalu...

Scripps Research study reveals new activation mechanism for pain sensing channel

... channels bind in a lock-and-key mechanism that is readily reversible," said Lindsey Macpherson, another author of the study and a Ph.D. candidate in the Scripps Research Kellogg School of Science and Technology. "The mechanism by which noxious compounds activate TRPA1 is unique. For example, compounds that ...

Why are lions not as big as elephants?

...herwise, leading to lower prey availability, could readily upset this energy balance. It may have also contributed to the extinction of the largest carnivores and explain why the largest modern mammalian carnivores are so rare and vulnerable today....

News tips from the Journal of Neuroscience

...ors found that histamine increased the size of the readily releasable pool (RRP) of vesicles, and specifically increased priming of the immediately releasable pool that are positioned near calcium channels. Expression of a DAG-insensitive mutant form of Munc13-1 abolished the histamine-induced potentiation o...

MIT creates 3-D scaffold for growing stem cells

...iously thought." The active motif method could be readily adapted to studying cell-to-cell interaction, cell migrations, tumor and cancer cell interaction with normal cells, cell-based drug testing and other diverse applications. "I believe that in the next 20 years all cell cultures will be in 3D with the...

Adenine 'tails' make tailored anchors for DNA

...ed to one end, which acts as "glue" because sulfur readily reacts with gold. But a potentially less expensive and even simpler approach, according to the NIST, NRL and UMD team, might be to use a string of adenine nucleotides as an anchor. Of the four nucleotides that comprise DNA molecules, adenine, turns ...

Treatments for urinary infections leave bacteria bald, happy and vulnerable

...to adhere to or invade the bladder tissues and are readily eliminated from the body." Pinkner and his colleagues think the bacteria will find it harder to evolve resistance to a treatment that does not directly impact their survival. According to an April 2006 National Institute of Allergy and Infectious Di...

Stem cells found in adult hair follicles may provide alternative to embryonic stem cells

...milar to other types of adult stem cells, they are readily accessible through a minimally invasive procedure and could lead to using a patient's own hair as a source for therapy without the controversy or medical issues of embryonic stem cells. "We see the potential for cell replacement therapy in which pa...

Midges send undeniable message -- planet is warming

...xoskeletons and the shells of crustaceans, doesn't readily degrade in the sediment of these lakes. The researchers determined the type of midges that lived in the lakes based on specific variations in certain head capsule structures, such as differences in the number, size, shape and orientation of teeth. ...

From hot springs to rice farms, scientists reveal new insights into the secret lives of archaea

... the ammonia into nitrites and nitrates, which are readily absorbed by plants or removed by other microbes. Animals and people, in turn, obtain nitrogen by eating plants and other herbivorous animals. That was the dogma taught for decades in biology classes-until September 2005, when David Stahl of the Uni...

Einstein researchers discover how a key dietary vitamin is absorbed

...ers. A water-soluble vitamin such as folate cant readily penetrate the fatty membrane of cells. It needs a specialized uptake mechanism so it can be absorbed by intestinal cells and ultimately enter the bloodstream. The Einstein researchers identified the membrane protein, dubbed PCFT/HCP1, that transports...

Blame myelin for many neuropsychiatric disorders

...nations that can be offered, one that doesn't come readily to mind is -- myelin. Conventional wisdom holds that myelin, the sheet of fat that coats a neuron's axon -- a long fiber that conducts the neuron's electrical impulses -- is akin to the wrapping around an electrical wire, protecting and fostering ...

Adult neurogenesis newly adult-born neurons are functionally similar to mature neurons

...d the adult-born cells fluoresced red, making them readily distinguishable in brain slices. Once they could tell the two types of cells apart, the researchers gained insight into the connections formed. They looked at glutamatergic (excitatory) nerves connecting the hippocampus with the entorhinal cortex, ...

Scientists find mutations that let bird flu adapt to humans

...vian flu virus. Most viruses, including influenza, readily swap genes with one another. In the new study, conducted by an international team of researchers, the viruses isolated from human patients in Vietnam and Thailand could recognize both human and avian cell receptors. By contrast, the viruses found in...

Silver bullet: UGA researchers use laser, nanotechnology to rapidly detect viruses

... values. With that information, a technician could readily reference a Raman shift for a particular virus to identify an unknown virus. To make their finding commercially viable, they're developing a business model, seeking venture capital and exploring ways to mass produce the silver nanorods. Next year, ...

Remote latrine reconfirms the presence of Essene sect at Qumran

...t I have ever studied in over 30 years and this is readily apparent," said Zias, who has done previous work on the Qumran burials. "For example, 2,000 years ago in Jericho, 14 kilometers to the north, the chances of an adult male dying after 40 were 49 percent. But when you go to Qumran, the figure for peopl...

Selecting life: Scientists find new way to search for origin of life

...rdial soup could be concentrated and selected on a readily available mineral surface. The challenge since has been to determine which of the countless biomolecules/surface interactions are the most likely candidates to the first steps to life. "Crystal surfaces are complicated," Hazen continued. "They hav...

10 million people a year are affected by zoonotic viruses spread by non-human hosts

...hat only about a quarter of zoonotic pathogens are readily spread from humans to humans" says Dr Heeney. "But it is believed that in extreme situations when certain animal viruses transmit to humans they may mutate and adapt to the new host so effectively that they may become almost exclusively spread from...
