Rare deficit maps thinking circuitry

...rticular part of chromosome 7. "Williams Syndrome yields a unique opportunity to study how genes influence our ability to construct our social and spatial worlds," said NIMH Director Thomas Insel, M.D. "By studying people with this disorder, we can discover how genetic mutations change not only molecular a...

Men from early middle ages were nearly as tall as modern people

...le Ice Age, which would have contributed to higher yields in agriculture. Also improvements in agricultural productivity that began in the 18th century made food more plentiful to more people. This study is part of the Global History of Health Project, an initiative funded by the National Science Foundation...

Protein fishing in America: The movie

...rd a device called a photon-stamping detector that yields key information on each detected photon. "The detection is highly sensitive and precise," Lu said. "One molecule doesn't have many photons give out. We need to capture as many photo-physical properties as we possibly can." On this project, Lu's grou...

Gold quantum dots have applications in biological labeling, nanoscale optics

Stanford researcher's findings may shed light on common, deadly birth defect

...s protein's action at varying developmental stages yields very different anatomical results - including one in which only the exterior, or the face, is affected while the scaffolding, or the brain, is left unscathed. The results not only shed light on a common cause of miscarriage in humans, they also help ...

Shedding new light on biology

...processing, the combination of the different views yields an unequaled three-dimensional (3D) image. PhD student Jan Huisken from the Stelzer group, one of the developers of the technology, sees the creation of SPIM as a major breakthrough in both the scientific and microscopy communities. "Not only is thi...

Babies with DiGeorge syndrome saved by immune supression, thymus transplant

...ause genetic testing for a defect on chromosome 22 yields a normal result, despite evidence of characteristic birth defects. This misleading finding can delay treatment, exposing an infant to risk of serious infection. The ideal time for a thymus tissue transplant is within three months after birth, Markert...

New model explains why costly insect 'outbreaks' hard to predict

...se. Taking into account so many dynamics yields a formula more complex and more useful than others that have been used to explain insect outbreaks. The model offers solutions for many of the insect-outbreak mysteries that have plagued ecologists for decades. For instance, scientists ha...

Carnivore species are predicted to be at increased extinction risk from human population growth

...s' biology with that on human population densities yields better predictions of extinction risk than either set of data can alone. For example, a species with a long gestation period that lives close to densely populated human areas are at greater risk than species with similar gestation periods that live n...

Climate change Qs & As

...und the world, whether from flooding, reduced crop yields or increased prevalence of asthma, diarrhea, malaria or other illnesses--is part of the climate-change story that hasn't really been told. That is why it's important to make the science underlying climate change accessible to policymakers in parts of...

A gene that keeps species apart

...bility is the male donkeyfemale horse cross, which yields a sterile mule, but many other cases have been documented among mammals, and thousands of plant crosses produce infertile offspring. To elucidate the molecular mechanisms of reproductive isolation, biologists must first identify candidate hybrid in...

Volcanic soils yield new clues about the emergence of powerful chiefdoms in Hawaii

...land systems on Maui and Hawai'i, where per capita yields were declining. They probably looked up the chain of islands toward Moloka'i and O'ahu and said, 'I'd love to get hold of those taro paddies.'" By the early 1800s, just a few decades after European contact, the remarkable agricultural system that onc...

Researchers target deficit irrigation for wine grapes

...uts growers a step closer to acceptable wine grape yields from cold-hardy vines that require less water. "Deficit irrigation looks promising, but it is not a beginner's tool. Growers need to bewell-versed in managing a vineyard using full irrigation before they try it," Hellman said. "Deficit irrigation req...

Domesticated tree crops may be the 'future of forestry'

... kind of technology could allow us to increase our yields and create tailor-made trees to meet society's demands for forestry products without encroaching on wilderness areas." The next step in Meilan's research will involve taking genes he identifies through gene and enhancer trapping, transferring those g...

Technique plucks rapidly evolving genes from a pathogen's genome

...ymine, cytosine and adenine - a TCA codon - always yields a serine amino acid, for example. Because 64 DNA triplets can be made from the four available DNA nucleotides but there are only 20 different amino acids, some amino acids are coded by more than one codon. Arginine, for example, is coded by six diffe...

Mantis shrimp may have swiftest kick in the animal kingdom

...ly conducting experiments which show that the blow yields a tremendous amount of force - well over a hundred times the mantis shrimp's body weight. In a short note appearing in the April 22 issue of the journal Nature, Patek and her colleagues, graduate student Wyatt Korff and professor of integrative biolo...

NJIT chemists pave way for cheap, usable field test for polluted, toxic, water, air, food

...sis systems. Miniaturization using nanotechnology yields many functional and economical benefits because of the reduction of a necessary sample size, the decrease in reagent consumption and the lower costs of mass production. However, scientists cannot sacrifice results to create alternatives. "Yes, ...

Bioreactor boosts chemical fermentation by 50 percent: study

...the bioreactor. Traditional fermentation typically yields only 50 grams per liter or less, making the new process 44 percent more effective. More important to Yang is the fact that he and his team were able to coax the bacterium P. acidipropionici to make more acid without adding chemicals to t...
