Prenatal Stress Keeps Infants, Toddlers up at Night, Study Says

...sed may play an active, causal role in priming the path for these childrens emotional and cognitive problems in later life, or if both conditions merely fall out of the same stressful pregnancies. Related studies now show that stress, which is associated with increased exposure stress hormones, like c...

Newly found sensing system enables certain bacteria to resist human immune defenses

...ug resistance, and these findings may help chart a path to designing new drugs to bolster our antimicrobial treatment options,” notes NIAID Director Anthony S. Fauci, M.D. Led by Michael Otto, Ph.D., of NIAID’s Rocky Mountain Laboratories (RML), the scientists used the gram-positive bacterium Staphyloc...

Researchers examine carbon capture and storage to combat global warming

...nology, Stanford researchers are exploring another path for cutting emissions of carbon dioxide, the leading greenhouse gas that causes global warming. Carbon capture and storage, also called carbon sequestration, traps carbon dioxide after it is produced and injects it underground. The gas never enters ...

Protein enables discovery of quantum effect in photosynthesis

... be sampled effectively to find the most efficient path for energy transfer. "We have a very detailed molecular structure of this protein and we understand the electronic properties of it very well, too," said Blankenship. "It's taught us a lot about how chlorophylls interact with proteins. It was i...

'Short-circuit' found in ocean circulation

...urrent that flows around Antarctica by tracing the path of helium from underwater volcanoes. The details are published in Nature this week. The team, led by Alberto Naveira Garabato of the National Oceanography Centre, Southampton (formerly based at the University of East Anglia), has discovered a 'short...

Flies don't buzz about aimlessly!

...a warm summer evening, especially since its flight path seems to be so erratic? Mark Frye at the Universit... the fractal patterns of a snowflake, a fly flight path appears similar whether viewed up close, or from a distance. The researchers also found that sea...

New player in commitment to life as a fat cell

...cursor cells for genes that switch on early in the path to fat formation. Using a novel method to rank genes, they found that XOR was at the top of the list of genes that fit the profile of a fat generator. Indeed, they found evidence that XOR controls PPAR-gamma a transcription factor considered to be...

UCSD researchers discover variants of natural tumor suppressor

...n the other hand, controls the driver on Akt1, the path involved with cell survival. Therapies directed at releasing the brake on this driver would allow cells involved in heart or neurological diseases to better survive. "Both PHLPP variants are important in cancer; the loss of a brake to any of the...

Fighting influenza & co. with 40,000 blood samples

...e age group that is mainly affected and a possible path of infection, this disease is also known as 'Students' Kissing Fever'. After the symptoms have disappeared, the pathogen, the Epstein-Barr virus, remains in the body for life and could permanently weaken the body's immune system with increasing age, ...

Genetic pathways to curable and incurable forms of pancreatic cancer identified

...sponsible for sending cells down the less-traveled path toward cystic pancreatic cancer versus the well-traveled route to the more fatal form of ductal pancreatic cancer. Sunil Hingorani, M.D., assistant member of the Hutchinson Center's Clinical Research and Public Health Sciences divisions, led a stu...

Angelman syndrome deficits rescued in mice

...s between UBE3A and CaMKII ?and if it's a specific path ?then that could be a therapeutic target." But the results may apply more broadly, Weeber said, to other types of mental retardation syndromes that remained unexplained and untreatable. "There are a lot of mental retardation syndromes that we s...

RNA enzyme structure offers a glimpse into the origins of life

...to arise billions of years ago on the evolutionary path toward the emergence of life. In all forms of life known today, the synthesis of DNA and RNA molecules is carried out by enzymes made of proteins. The instructions for making those proteins are contained in genes made of DNA or RNA (nucleic acids). ...

Researchers discover new details about HIV-1 entry and infection

...ngerhans cells (LC) and CD4+ T cells. However, the path of entry and fate of infection was different for the two cell types. Infection of CD4+ T cells appears to rely at least in part on expression of major HIV-1 coreceptors like CCR5, whereas pathways for infection of vaginal LC appear to be more diverse...

Cracking open the black box of autoimmune disease

...ng immune system activity. "This may shorten the path to new therapies for autoimmune disease," says Whitehead Member and MIT professor of biology Richard Young, senior author on the paper that will appear January 21 online in Nature. "With this new list of genes, we can now look for possible therapies ...

NASA snow data helps maintain nation's largest, oldest bison herd

...trong, with the changing seasons determining their path and destination. Now, NASA satellite data and computer modeling and U.S. Department of Agriculture (USDA) information are helping track the remnants of this once mighty herd in Yellowstone National Park as they migrate with the melting snowpack. The...

...don't commit themselves to the right developmental path at the right time, they're very likely to die or to begin an inappropriate type of reproduction. Acute leukemias and other forms of cancer cells derive from defects such as this. Understanding the processes by which they form will require pinpointing...

Weighty viruses

... is sent to a CCD camera, which records the flight path of the trapped particle. The rest of the light goes to a measuring device that precisely analyzes the scattering signal. The scattered light is different from the initial light beam because the virus particle in the electric field of the ion trap beg...

Hopkins scientists link immune response to 'ghost' parasites and severely congested sinuses

...to cut away inflamed tissue and polyps, clearing a path for the sinuses to drain normally. Lane says that if left untreated, polyps can lead to severe blockage and recurring infections. All patients were monitored for a minimum of nine months to see if polyps and their resulting symptoms returned. T...

Mysterious 'neural noise' actually primes brain for peak performance

... of Brain and Cognitive Sciences have blazed a new path to understanding our gray matter. The traditional approach has assumed the brain uses the same method computation in general had used up until the mid-80s: You see an image and you relate that image to one stored in your head. But the reality of the ...
