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

...ged how depressed or anxious they were at multiple points early on in, late in, and after their pregnancy. Later on, the women were then asked to report on their childs sleep habits at 6, 18 and 30 months, detailing how long the child slept (a consolidated daytime and nighttime total), how often the child a...

Cellular message movement captured on video

...th factors and they are also structural attachment points that link the extracellular world to the protein filaments and tubes that comprise a cell’s internal cytoskeleton. While researchers showed that paxillin serves as a docking station for a variety of signaling and structural proteins, they have be...

Researchers examine carbon capture and storage to combat global warming

...see that proper procedures are followed. Benson 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...

Exploring the dark matter of the genome

...ery dangerous. They are viruses -- literally." She points out that during subsequent sequencing efforts, DNA was made three times from the same strain of flies -- in 1990, 1998, and 1999 -- and that new patterns of transposons were found in each. "We can see intact transposons moving from one position to th...

Marine phytoplankton changes form to protect itself from different predators

...solve the dispute, Hay believes it shows that both points of view could be correct – depending on which form the organism has taken. “It depends on the environmental context, which we are appreciating more and more in ecology and in biomedical research,” he added. “Some of these differences are small, b...

Gene responsible for common hearing loss identified for first time

...ference. “The gene in which the variant is located points to a pathway that contributes to the disease. This may be a lead for better forms of treatment in the future; currently the best option is an operation. However, there is often an additional component of hearing loss which can’t be restored by surger...

Researchers develop buckyballs to fight allergy

...journal. “This discovery is exciting because it points to the possibility that these novel materials can one day lead to new therapies,” said Chris Kepley, Ph.D., M.B.A., assistant professor in the Department of Internal Medicine, Division of Rheumatology, Allergy and Immunology at the VCU School of Medi...

Scientists close in on missing carbon sink

...of air collected by research aircraft over various points of the globe for the past 27 years. The air samples had been analyzed by several labs around the world, which used them to investigate various aspects of the carbon cycle, but this was the first time that a team of scientists analyzed them to obtain ...

A first -- Hebrew University scientist observes brain cell development in 'real time'

...spread out to reach other neurons and serve as the points of communication between the neurons. The model employed by Dr. Mizrahi in his research was the newborn neuron population which develops into the olfactory bulb of adult mice, providing them with a sense of smell. The development and maintenance ...

More recycling on the farm could reduce environmental problems

...ice premiums could overcome this disadvantage, and points out that social benefits could be expected. Pearson argues that existing funding programs for farmers could be modified to encourage more regenerative agriculture, and suggests that philanthropists and professional bodies could stimulate its uptake....

Madagascan tropical forests return thanks to better management and well-defined ownership

...the authors behind the new study. The new study points to the large capacity of dry tropical forests to spontaneously regenerate if existing local rules and norms (including well-defined property rights) mitigate other drivers of deforestation and alternative land-use. ...

Brain's white matter -- More 'talkative' than once thought

...yelin-rich white matter are far from synapses, the points of contact between nerves where glutamate is released. Theorizing that OPCs might have experienced glutamate in some less obvious way in this area of the brain, Bergles and his team studied nearby nerve cells to figure out where the glutamate mig...

Invasion of the island bats

...as, exchanging species back and forth at different points in their geological history. This discovery further enhances the conservation importance of the West Indies, where habitat loss and climate change —embodied in the intensification of hurricanes?threaten natural habitats more acutely than on the conti...

DOE JGI sets 'gold standard' for metagenomic data analysis

...nd existing approaches for metagenome analysis and points out their weaknesses," said Natalia Maltsev, of the Bioinformatics Group, Mathematics and Computer Science Division at Argonne National Laboratory. "The simulated datasets constructed by the authors provide a much-needed test bed for evaluation and ...

DNA-damage test could aid drug development

...Union is trying to minimize animal testing," Shuga points out. "A ban on animal testing of cosmetic products goes into effect in 2009." Next steps in the research, which may be carried out by industry partners, will be to test the assay in rats and other organisms, and with a wide variety of other toxic ...

Dinosaur hearing, listening to muscle noise, quieter cubicles

...the shallow-water (less than 20 meters deep) choke points of harbor entrances, which often have high levels of ambient noise. Peter J. Stein ( pstein@scisol.com ) of New Hampshire-based Science Solutions, Inc. will present the Swimmer Detection Sonar Network (SDSN), designed to be a cost-effective method to...

Gene thought to assist chemo may help cancer thrive

...the cells that were damaged by chemo. But McDonald points out that p53 can also help repair damaged cells. If p53 is repairing cancer cells, that may lead to cancer recurrence. "We think p53 may actually help some cancer cells make a comeback,?he said. "Based on our results, we propose that p53 may help...

Man's best friend lends insight into human evolution

... when an experimenter (or another chimp) helpfully points to hidden food. This is a skill that humans already display in infancy, and according to Hare it seems to have evolved since the human lineage split from that of chimps a few million years ago. For Hare, who has worked with a number of different a...

Noise echoes in cell communications

...noise is the secret of life," suggests Martin, who points to the constant movement of particles under a microscope to illustrate this phenomena. Unlike a physics experiment that can produce the same result after various attempts, in biology, one particular experiment can yield a multitude of outcomes. Th...
