Research team identifies new Alzheimer's gene

...se is the most common form of disabling memory and thinking problems in older people. The progressive neurological disorder afflicts an estimated 5 million Americans, a number expected to triple by 2050. “We have entered a new era in medical research. Today’s technologies permit us to survey a sufficient ...

Studies to find better ways to preserve human eggs, ovarian tissue under way

...your fertility is the most important thing you are thinking or talking about, but there are a lot of women interested in talking about it,” says Dr. Emmi. She hopes her work with Dr. Ying C. Song, cryobiologist, will one day give her more to say. They are collecting ovarian tissue from volunteers age 16 to...

Researchers examine carbon capture and storage to combat global warming

...son points to a familiar technology as a model for thinking about and tackling risk. ''People often ask, is geological storage safe" It's a very difficult question to answer. Is driving safe"'' she expounded. ''You might say yes or no, but what makes driving something we're willing to do" You get automaker...

Penn researchers link cell's protein recycling systems

...urology. “The new finding directly challenges this thinking by showing that one system can be induced to compensate for the other. Cells are able to shift proteins between the systems. We think that this molecular link can be used to benefit a wide variety of neurodegenerative diseases because accumulation of...

Endosome-mediated signaling in plants

...as in animals. "These findings will influence our thinking of the evolutionary origins of endosomes and hopefully help us to understand why cells use them as signaling compartments," noted lead author of the paper, Dr. Niko Geldner. Endosomes were once thought to function solely in the inactivation of rec...

Putting feelings into words produces therapeutic effects in the brain

Traumas like Sept. 11 make brains more reactive to fear

...erience lingering symptoms (bad dreams, jumpiness, thinking about the incident and avoiding the site of the trauma), but they are not severe. However, the kinds of changes that these traumas cause in the brain, the researchers suspect, create vulnerability to developing future mental disorders. Specifically...

Tundra disappearing at rapid rate

...adually but can surge ahead. "The conventional thinking on treeline dynamics has been that advances are very slow because conditions are so harsh at these high latitudes and altitudes," said Dr. Ryan Danby, from the Department of Biological Sciences. "But what our data indicates is that there was an upslo...

Brain's reward circuit activity ebbs and flows with a woman's hormonal cycle

...circuitry includes: the prefrontal cortex, seat of thinking and planning; the amygdala, a fear center; the hippocampus, a learning and memory hub; and the striatum, which relays signals from these areas to the cortex. Reward circuit neurons harbor receptors for estrogen and progesterone. However, how these h...

Imaging pinpoints brain regions that 'see the future'

...ember the past, they're also not at all good about thinking about what they might be doing tomorrow or envisioning any kind of personal future," McDermott explains. They comprehend time and can consider the future in the abstract sense (e.g., that global warming is a concern for the future), but they cannot v...

Common gene version optimizes thinking -- but with a possible downside

...t a version of a gene that optimizes their brain's thinking circuitry, yet also appears to increase risk for s...ral and functional connectivity and performance on thinking tasks, likely by increasing gene expression. In 257 affected families, people with schizophrenia wer...

Microbes start immune response by sneaking inside cells

...boratory animal studies ?offers a different way of thinking about how best to design future human vaccines, as well as drugs that could more precisely target the body’s inflammatory response in rheumatoid arthritis and some other autoimmune diseases. “In our study, the presence of bacterial microbes inside...

Why aren't humans furry? Stone-Age moms could be the answer

... paper is an excellent example of the kind of bold thinking and theorizing which David Horrobin intended to encourage when he began Medical Hypotheses. I hope that Judith Rich Harris' idea provokes debate and further investigation of this topic." ...

Shedding new light on proteorhodopsin

... to replace respiration was still unknown. "Our thinking was that if you had a system that could harvest energy from two different sources and you knocked out one of those sources then you would probably maximize the alternative energy source," Liphardt said. "Think of it like a capacitor. If a capacitor ...

Infection detectives use disease 'fingerprints' to track common infections in children

...analysis in their offices, researchers are already thinking about a possible way they could send in the results from the chip and get the analysis back via the Internet, for example. "Pediatricians understand that this could change the way we do things," said Dr. Ramilo, who leads pediatric infectious dise...

Researchers first to map gene that regulates adult stem cell growth

...wide variety of future genetics studies. "We're thinking about cancer in a big way," Van Zant said. "This is a great example of translational research ?from the most basic type of genetic research all the way to possible treatments for patients." One big obstacle chemotherapy patients face is stem cell ...

Bird sex is something else

...scriptional level. The study challenges current thinking about the role and mechanisms of dosage compensation in species with heteromorphic sex chromosomes. "Unlike mammals, birds have an ineffective dosage compensation," says Arnold. "The finding is surprising because dosage compensation was previously th...

Deep in the ocean, a clam that acts like a plant

Cells use 'noise' to make cell-fate decisions

... chemical composition." Conventional scientific thinking has been that the random nature of such fluctuations within cells interferes with the reliable operation of biological systems. However, Dr. Süel's research team hypothesized that noise in one particular genetic circuit might be beneficial, linked to...

Moonlighting enzyme linked to neurodegenerative disease

...o after the enzyme responsible for the degradation thinking it probably might play an important role in the regulation of frataxin and could represent a target therapy for Friedreich's ataxia," says Dr. Isaya. The severity of Friedreich's ataxia is proportional to the decrease in the levels of frataxin: th...
