Gene Expression in the Aging Brain

...o live much longer than a century. Even though the advances of the modern age may have extended the average human life span, it is clear there are genetic limits to longevity. One prominent theory of aging lays the blame on the accumulation of damage done to DNA and proteins by “free radicals,?highly reactive...

Missing fossil link 'Dallasaurus' found

... two decades, many new discoveries and significant advances have been made in the understanding of mosasaur ev...tion and how they lived. Dallasaurus significantly advances that understanding by filling in a long missing piece of mosasaur evolution, specifically a time at ...

Membrane research opens window to benefits for plants, humans

...two continents, potentially could open the gate to advances in both plant and human health. The research, which appeared online this month in advance of regular publication by the journal Nature, involved a tandem of basic-science firsts that offer immediate real world applications, the scientists say. Firs...

University of Arizona plant scientists to unravel maize genome

...ce the corn genome sequence is in our hands, these advances can happen much faster," Wing said. Corn is one of the most important economic crops in the United States, and, together with rice, accounts for 70 percent of worldwide food production. The production of corn-based products with enhanced nutritional...

Bacterial protein mimics host to cripple defenses

...Boyce Thompson Institute (BTI) for Plant Research, advances the understanding of a disease mechanism common to plants, animals, and people. That mechanism, called programmed cell death (PCD), causes a cell to commit suicide. PCD helps organisms contain infections, nip potential cancers in the bud, and get ri...

Cyberkinetics, Case to develop system to help restore extremity function

...system diseases and disorders by bringing together advances in neuroscience, computer science and engineering. Cyberkinetics' products are based on over ten years of technology development and cutting-edge neuroscience research at leading academic institutions such as Brown University, the Massachusetts Insti...

Delaware scientists make significant advance in study of small RNAs

...ribed about 12 years ago, but the most substantial advances in this field have only been made in the last six or seven years. To assist other small RNA researchers, the UD team has created a user-friendly web site [ http://mpss.udel.edu/at ] available to scientists to examine any gene or region of an Arabido...

Minimally Invasive Cancer Treatments Highlighted

...collaboration across disciplines is the key to new advances and better patient care,?says Michael Soulen, M.D., symposium co-chair. “The need for better cancer treatments is great, and interventional radiologists provide targeted cancer treatments directly to the tumor without significant damage to the nearby...

UF study first to quantify validity of DNA I.D. tool using marine snails

...archer. That may be possible thanks to scientific advances that include the first test quantifying the effectiveness of a DNA identification tool among brightly colored shells. With an error rate as low as 4 percent, two UF scientists have been able to identify cowries collected from around the world by anal...

Applying ecological laws to bacteria

...to obtain. Combined with the amazing technological advances made in environmental microbiology, we hope that we will be able to predict how these communities respond to changes in their environment, as well engineering these communities to perform useful tasks.' Island size and bacterial diversity in an arch...

Fighting malaria by manipulating mosquitoes' sense of smell

...ent of complementary control technologies. Recent advances in the genetics, biology, immunology and behavior of mosquitoes open up new and unexplored avenues for controlling malaria and other mosquito-borne diseases. The goal of the Vanderbilt-led research team is to pursue one of the most promising of these...

Discarded placentas deliver researchers promising cells similar to embryonic stem cells

... cells relatively easily. "Provided that research advances to the point that we can demonstrate these cells' true therapeutic benefit, parents could conceivably choose to bank their child's amniotic epithelial cells in the event they may someday be needed, as is sometimes done now with umbilical cord blood,"...

Israeli scientists successfully transplant frozen-thawed ovaries in sheep

...emature ovarian failure, and furthermore, that the advances they have demonstrated from new freezing techniques may have potential for other human organ transplants, which are currently done using only fresh grafts. Co-author Yehudit Nathan, program manager at Core Dynamics, the biotech company that funded a...

Virus uses tiny RNA to evade the immune system

...m that has greatly contributed to major scientific advances about how genes work. To launch their study, Grundhoff wrote a computer program to screen the SV40 genome for possible microRNA precursors. MicroRNAs are made from messenger RNA molecules with distinctive hairpin folds. The hairpin structure is dice...

Single gene is genetic switch for fly sexual behavior

... the male version of the protein also make amorous advances toward male flies that express female pheromones. In these cases, "we have been able to reverse the sex roles during Drosophila courtship," Dickson and Demir say. Dickson and Demir created male-spliced versions of fruitless in female flies and femal...

Researchers find how some antibiotics kill bacteria

...ia in the same way. But the new study used recent advances in X-ray imagery to obtain the highest resolution ... rifabutin on E. coli RNA polymerase. With recent advances in X-ray crystallographic studies of RNA polymerase, the researchers could determine exactly where a...

Genomics researchers discover protein deficit that causes drug toxicity

...ransplants. The Mayo researchers say their finding advances the field of pharmacogenomics, which tailors medicine to a patient's personal genetic makeup. In the current issue of the Proceedings of the National Academy of Sciences, (http://www.pnas.org/cgi/content/abstract/102/26/9394) Mayo researchers report...

A Father’s Day Gift: Free DNA Paternity Testing

...cessible and vulnerable than ever because of rapid advances in exploration technology, the report says. Known as "extremophiles," the genetic make-up of organisms of the deep that live in extreme conditions of pressure, temperature and toxicity is drawing enormous interest from scientists and companies biopr...
