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

...cal Center. This is another piece in the unfolding mystery of just how much the prenatal environment may shape a childs health and development for years to come. The survey-based study, part of the Avon Longitudinal Study of Parents and Children (ALSPAC), assessed pregnant women living in Avon, England, w...

Undergraduate research shows leaderless honeybee organizing

...t to researchers studying social behavior, a great mystery still remains regarding how bee societies effectively direct and coordinate complex operations without a central controlling intelligence. Pierce’s finding is part of an ongoing research effort in Schneider’s lab aimed at understanding the mechanisms...

Small, self-controlled planes combine plant pathology and engineering

...g plant and animal pathogens and remains largely a mystery to scientists who do not have a firm understanding of its ability to travel long distances in the atmosphere. By placing antibiotics in the sampling collection plates, researchers can ensure that only Fusarium will grow on the plates. Over the course...

Herpes virus hijacks DNA repair process

...age response benefits viral replication is still a mystery and a topic of continuing investigation in the Virgin lab. "The discovery that induction of the cells' DNA damage response is an intentional viral strategy, rather than a passive cellular response to viral invasion, means that we should look into ...

Puzzling plankton yield secrets to role in evolution/global photosynthesis

...ny green algae have provided new insights into the mystery of how new species of plankton evolve—and further highlights their critical role in managing the global cycling of carbon. These findings, by a group led by the DOE Joint Genome Institute (DOE JGI); the Scripps Institution of Oceanography, Universit...

Study offers clues to 'Broken Heart Syndrome'

...ms as if the patient is having a heart attack. The mystery deepens in the cardiac catheterization laboratory, when the interventional cardiologist finds no blockage in the coronary arteries. To date, the registry has enrolled 40 patients diagnosed with Takotsubo cardiomyopathy at two major hospitals in R...

Decoding protein structures helps illuminate cause of diabetes

...uctures, the steps in between remain somewhat of a mystery and may hold clues to what drives the transition, says UW-Madison chemistry professor Martin Zanni, who led the new study. In trying to understand diabetes, "people have been looking at the fibers, but they should be looking at their formation," h...

Cloning the smell of the seaside

...ell like the seaside ?and bottled it! The age-old mystery was unlocked thanks to some novel bacteria plucked from the North Norfolk coast. Prof Andrew Johnston and his team at UEA isolated this microbe from the mud at Stiffkey saltmarsh to identify and extract the single gene responsible for the emission...

Penn study on olfactory nerve cells shows why we smell better when we sniff

... driving force for such synchronization remained a mystery for more than 50 years," says senior author Minghong Ma, PhD, Assistant Professor of Neuroscience. "These results help us understand how the mammalian olfactory system encodes and decodes odor information in the environment." Researchers tested tw...

Researchers discover gene crucial for nerve cell insulation

...scientists' research also resolved a long-standing mystery surrounding why a single mutant copy of the EGR2 gene disrupts the functioning of the normal EGR2 gene, leading to a disorder of the nervous system. In many genetic conditions, the unaffected copy of an affected gene continues to produce its prote...

University of Alberta researchers unravel intricate animal patterns

... the entire group—a finding that helps unravel the mystery that has plagued scientists for years. "It is known that there is a connection between the signals animals use to communicate with each other and their behaviour," said Raluca Eftimie, a graduate student in the U of A’s Centre for Mathematical Biolo...

Cartilage discovery offers arthritis hope

...ucture of these fibres or 'fibrils' has remained a mystery for more than 40 years, so hindering any progress towards the development of potential therapies. Now, a team from The University of Manchester has used sophisticated electron microscope techniques to uncover the molecular structure of the thinner ...

Researchers find 6,000-year-old fossil evidence

...ticated and wild plants, Perry determined that the mystery starch was a chili pepper. "We knew from historic and ethnographic records that people were eating domesticated chili peppers, but this archaeological evidence confirms those findings. It also shows us that chili peppers are one of the oldest dome...

Chemical switch triggers critical cell activities

...n like a baton to another enzyme, has solved a key mystery to how cells control some vital functions, according to investigators at St. Jude Children's Research Hospital. A report on this work appears in the January 14 advanced online publication issue of Nature. The St. Jude discovery explains how a simpl...

Studies yield insight into the numerical brain

...rs also said their findings offer insight into the mystery of how the brain learns to associate abstract symbols precisely with quantities. Both studies reveal in unprecedented detail how structures in the parietal cortex--the region of higher cognitive processing just above the forehead--activates during p...

Pregnancy hormone key to repairing nerve cell damage

The mystery of why multiple sclerosis (MS) tends to go into remission while women are pregnant may be the secret to overcoming the devastating neurodegenerative disease, according to University of Calgary researchers who have shown that a pregnancy-related hormo...

MIT biologists solve vitamin puzzle

Solving a mystery that has puzzled scientists for decades, MIT and Harvard researchers have discovered the final piece of the synthesis pathway of vitamin B12-the only vitamin synthesized exclusively by microorganisms. B12, the most chemically complex of all vitamins...

Tears reveal some of their deepest secrets to researchers

... exactly what our tears are made of has remained a mystery to scientists. A new study sheds some light on the complex design of tears. What we think of as tears, scientists call tear film, which is made up of three distinct, microscopic layers. The middle, watery layer ?what we normally think of as tears wh...

Microfluidic chip helps solve cellular mating puzzle

...hns Hopkins researchers has solved a long-standing mystery related to the mating habits of yeast cells. The findings, described in the Feb. 18 Advance Online Publication of the journal Nature, shed new light on the way cells send and receive signals from one another and from the environment through a proc...

Baby fish 'smell their way home'

... How the fish learn the unique smell of home is a mystery still. The researchers theorise that it is imprinted on them either when they are an egg inside their mothers, a fertilised egg swept around on the bottom, or new-hatched fry loose in the stream or brooded in their parents' mouths. "An egg, even a...
