... separate, departmentally based specialties, often functioning independently of each other," explains Kimmel. "But it has become clear that progress in medicine is a dynamic, multi-faceted process. The conventional divisions within biomedical research may hamper the pace of scientific discovery and ultimately, d...

Offspring at risk from maternal occupational exposure to solvents

...sed women had significantly lower verbal cognitive functioning than the non-exposed children in the control group. We also saw greater inattention and hyperactivity in the exposed children," said Dr. Maru Barrera, a co-author of the study, a psychologist and associate scientist at Sick Kids, and an associate pro...

Experts present new research on hot topics in aging at GSA's annual meeting in Washington, DC

...processing) improved cognitive abilities and daily functioning in older, independent-living adults (n=2,802; mean age = 73.6 yrs). Participants were assessed at baseline, immediate post-test, 1 year, and 2 years with a comprehensive battery of cognitive tests and measures of function. Each training intervention ...

Purdue chemists give an old laboratory 'bloodhound' a sharper nose

...logan cautioned that a better understanding of its functioning was still needed. "One potential criticism of the device is that we haven't yet done an in-depth analysis of the mechanism," he said. "We think we know how it works, but haven't yet proven it. That's one of our next research steps." ...

Research gaining momentum by silencing genes

.... Not only will this lead to new insights into the functioning of plant cells, which is important for agriculture and nutrition, but it will also shed light on the role of animal and human genes. More and more, scientists are discovering that biological processes in animals and humans are comparable to processes...

Latest buzz in research: Intoxicated honey bees may clue scientists into drunken human behavior

... bees and humans in similar ways it impairs motor functioning along with learning and memory processing," said Julie Mustard, a study co-author and a postdoctoral researcher in entomology at Ohio State University. Researchers gave honey bees various levels of ethanol, the intoxicating agent in liquor, and monit...

Brain differences in adolescents, psychopaths, lend to their impulsive, risk-taking behavior

...nd animals--shows differences in the structure and functioning of adolescent brains compared with preadolescents or adults that correspond to such teenage behaviors as immature decision making, increased risk taking, and impulsive behaviors. As a result of this research, scientists now urge that puberty be studi...

Military hazards are greater for Native Americans, according to sociological research

...difficult to gain information about bases that are functioning currently, the study examined publicly released documents from the U.S. Army Corps of Engineer relating to closed military bases in the approximately 3,100 counties in the contiguous 48 states. The research focused on sites containing unexploded ordn...

Stress impairs thinking via mania-linked enzyme

...carbamazepine protected monkeys' prefrontal cortex functioning from impairment by a norepinephrnine-like drug. The researchers traced impairment to a reduction in memory-related firing of single cells in the prefrontal cortex, which was reversible by a PKC inhibitor. Genetic and biochemical studies indicate th...

UNC Lineberger researchers identify molecular markers of aging

...s said. "As people age, they could just run out of functioning stem cells." Depletion of stem cells could affect the ability of the body to heal after injury or surgery and may also predict the ability of certain diseases, such as cardiomyopathy, to progress," he added. Along with Sharpless, study co-...

Global warming's impact on US plants, animals determined from review of dozens of studies

Parmesan's similar findings involving an even larger statistical review of global warming's impact on plants and animals around the world appeared in a January 2003 issue of Nature . The Pew report, "Observed Impacts of ...

Research effort seeks A's to gene expression Q's

...urned on, others off---is an essential part of the functioning of an organism. It also can indicate, or be a factor in, many diseases. The mechanisms of gene regulation are poorly understood---recent research, for example, suggests that a great deal of gene regulation information may be encoded in long stretches...

Sex-determining genes of infectious fungus resemble human Y chromosome

...ause disease, most commonly in patients who lack a functioning immune system, such as organ transplant recipients and those with HIV/AIDS, Heitman added. A single fungal mating type spurs the vast majority of all C. neoformans infections, he explained, suggesting that sex determination and virulence are closely ...

Gene exchange between species is aided by parasitism

...ago. Three Plantago species possess both a normal, functioning copy of atp1 and a second defective atp1 that bears a striking resemblance to the atp1 gene found in parasitic "dodders" in the plant genus Cuscuta. Evidence suggests Plantago weeds acquired the defective atp1 through horizontal transfer recently -- ...

In a tiny squid, bacterial toxin governs organ development

Researchers call for studies on role of BRCA1 mutations in chemotherapy response

...Because BRCA1 is involved in DNA repair, loss of a functioning BRCA1 gene may make a cell more vulnerable to chemotherapy agents that damage DNA, such as platinum-based compounds. In addition, BRCA1 has also been shown to be involved in the regulation of cell division, and loss of the gene has been proposed to p...

No getting around RET

...otype, in which the absence of enteric neurons and functioning kidneys results in death soon after birth. In vitro studies and the proximity of RET-independent GFR and RET-expressing cells in some developmental regions, however, have prompted strong speculation that GFR might be able to operate even in the absen...

Researchers reconstruct parts of the genome of a common mammalian ancestor
