Scientists detect probable genetic cause of some Parkinson's disease cases

... families with a history of Parkinson'sdisease who lived in the Basque region of Spain and in England.In these new studies, the researchers sought to determine theprevalence of the genetic mutation in other families and individualsbeing studied by the Parkinson's Study Group with NINDS support.

Research on Worms Yields Clues on Aging

...ed to drugs used to treat epilepsy inhumans, worms lived longer and retained youthful functions longer thannormal.Because the drugs affect nerve signals, the researchers' observationssuggest that the nervous system influences aging processes. Thefindings are reported in the January 14 issue of the journal ...

Study finds more than one-third of human genome regulated by RNA

... last common ancestor of mammals and chicken,which lived 310 million years ago. "This study is an excellent exampleof the power of comparative genomics to illuminate how human genes areregulated," says Burge."As more genome data becomes available and the technology becomes moresophisticated, I think we'll ...

Taking Aim With Nanoparticle PEBBLEs

...even tailored to home in on cancer cells, the rats lived twice as long. With targeted PEBBLEs, some rats were still alive and active two months later, and MRI images showed that their tumors had vanished. Kopelman and coworkers plan to tinker with the PEBBLEs a bit more before trying them on larger number...

Elephants imitate truck noises, other animals

... Calimero, a 23-year-old male African elephant who lived for 18 years with two female Asian elephants in a Swiss zoo, was a nearly perfect mimic for the chirp-like calls of his long-time zoo mates. The chirps are made by Asian elephants but not by African elephants. Calimero often mimicked the chirps but r...

Deficiency of growth hormone and IGF-1 reduces cancer and kidney disease, but creates other problems

...ent increase in lifespan. All animals in the study lived until they died of natural causes. The researchers used several tests to measure memory and learning. They found that growth-hormone-deficient rats had impaired learning ability compared to normal animals of the same age. A similar pattern occurred ...

First technology to remove prions that cause vCJD from blood launched

.... Many nations ban blood donations from people who lived or visited countries where BSE infected cattle have been found. These donor deferral measures have put increased pressures on the availability of adequate supply of blood for transfusion. As the donor population becomes even more limited with each a...

Measles Deaths Worldwide Drop By Nearly 40% Over Five Years

...brain damage. "In many places where families once lived in fear of losing their children to measles, they're now protected by an effective and inexpensive vaccine," said Carol Bellamy, Executive Director of UNICEF. "What clearer proof could there be of the value of investing in immunization?" The dramati...

Evidence of 600-million-year old fungi-algae symbiosis discovered in marine fossils

...ncient ocean life. At a site where abundant algae lived in a shallow sub-tidal environment about 600 million years ago, Yuan and Xiao found three specimens that have evidence of two partners in a familiar relationship. "Enlargements of thin-section photomicrographs of the tiny specimens -- each of which w...

Ancient DNA helps clarify the origins of two extinct New World horse species

...to the same species. Thus, only two horse lineages lived in North America during the Late Pleistocene, the stilt-legged horses and the caballines. Though the different horses in each species "varied in size and shape quite a bit" regionally and temporally, Cooper explains, "we see no genetic evidence that ...

New method shows it is possible to grow bone for grafts within a patient's body

...d by filling the space with new bone. The approach lived up to their highest expectations. Working with mature rabbits, a species with bones that are very similar to those of humans, the researchers were delighted to find that this zone, which they have dubbed the "in vivo bioreactor," filled healthy bone ...

Neandertal femur suggests competition with hyenas and a shift in landscape use

...a hyena den at about the same time that the humans lived in it, the authors say. Archeological evidence indicates that humans processed carcasses of the same animals as the hyenas, with some animal bones showing both cut marks from human tools and tooth marks from hyenas. Additionally, the human femur was ...

New protein vital for immune response is found in surprise location

...mitochondria originally evolved from bacteria that lived within a host organism's cells, eventually developing a symbiotic relationship with host cells. Now that mitochondria are an integral part of our cells, Dr. Chen speculated that mitochondria may have acquired new functions by serving as a sentinel to...

Scientists find that protein controls aging by controlling insulin

...ore of the protein than in normal mice. Those mice lived between 19 percent to 31 percent longer than normal mice. The researchers were especially interested in how the hormone affected insulin, because making an animal resistant to insulin increases its lifespan ?a phenomenon found in animals ranging fr...
