Cerebral palsy (CP) has increased in infants born prematurely in the United States, according to new data.

Large-sized gastropods dating from only 1 million years after the greatest mass extinction of all time, the Permian-Triassic extinction, have been discovered by an international team of researchers. These specimens call into question the existence of a "Lilliput effect", the reduction in the size of organisms inhabiting postcrisis biota, normally spanning several million...
Researchers have accomplished a technical breakthrough: they mapped all the fragile sites of a living organism, the budding yeast Saccharomyces cerevisiae. The method used by the researchers can be applied to humans.
The first head-to-head comparison of therapeutic monoclonal antibodies produced from plants versus the same antibodies produced from mammalian cells has shown that plant-produced antibodies can fight infection equally well. Scientists conducted the comparison as a test of the potential for treating disease in developing nations with the significantly less expensive plant-based production...
Faces play a very important role in our social life. We make complex social decisions based on facial appearance. But we know little how we make a preference decision when the two faces are closely matched (e.g., age, race, gender, gaze, facial attributes, facial emotion). Is there any specific brain activity pattern associated with our preference (or non-preference)? Can these patterns be...
When metals are shaped, the materials they are made of are often damaged in the process. One cause of this is excessive press force, which cracks and perforates the material. By running simulations on a PC, research scientists can now calculate how to avoid component defects.
Researchers have identified three genes as a source of stuttering in some people. Mutations in two of the genes have already been implicated in rare metabolic disorders involved in cell recycling, while mutations in a third, closely related, gene have now been shown to be associated for the first time with a disorder in...
Treatment of prostate cancer using a very low dose of nitroglycerin may slow and even halt the progression of the disease without the severe side effects of current treatments, researchers have discovered.
The nucleus of one form of carbon is much larger and more stable than expected.
Members of a group or team will work harder when they're competing against a group with lower status than when pitted against a more highly ranked group, according to a new study. The results run contrary to the common belief that underdogs have more motivation because they have the chance to 'knock the higher-status group down a...
Workers and residents exposed to dust and fumes caused by the collapse of the World Trade Center on Sept. 11, 2001, frequently reported headache years later, according to new research.
Research has opened the door for the advancement of a new category of painkillers, called TRPV1 antagonists. These drugs block the transient receptor potential vannilloid-1 (TRPV1) channel, which is the same receptor responsible for the sensation of hotness from hot peppers.
A newly developed 9 cubic millimeter solar-powered sensor system is the smallest that can harvest energy from its surroundings to operate nearly perpetually.
Some women are especially sensitive to the natural flux of hormones in the menstrual cycle. New research points to a gene that likely influences how women respond to swings in estrogen levels and could help diagnose and treat premenstrual dysphoric disorder and inform treatments during menopause, such as hormone replacement therapy, researchers...
Evidence from the Challenger Deep -- the deepest surveyed point in the world's oceans -- suggests that tiny single-celled creatures called foraminifera living at extreme depths of more than ten kilometers build their homes using material that sinks down from near the ocean...
Honey bees warn their nest mates about dangers they encounter while feeding with a special signal that's akin to a "stop" sign for bees. When foragers were attacked by competitors from nearby colonies fighting for food at an experimental feeder, they produced a specific signal to stop nest mates from recruiting others to the dangerous...
To find the causes for cancer, biochemists and developmental biologists retraced the function of an important human cancer gene 600 million years back in time. For the first time, they have identified the oncogene myc in a fresh water polyp and they have shown that this oncogene has similar biochemical functions in ancestral metazoan and in...
Microbial enzymes are commonly used to reduce the levels of contamination created by industrial processes. Researchers have now characterized xylan-degrading enzyme from the the bacteria Paenibacillus barcinonensis, an isolated microorganism found in the Ebro delta.
Researchers are conducting the first FDA-approved clinical trial to determine whether an infusion of stem cells from umbilical cord blood can improve the quality of life for children with cerebral palsy.
Besides the 92 elements that occur naturally, scientists were able to create 20 additional chemical elements. These new elements were produced artificially and are all very short-lived: they decay in a matter of a split second. However, scientists predict the existence of even heavier elements with an extreme longevity. Scientists have now developed and applied a measuring apparatus that might...
Scientists have developed an amplitude gating technique that gives physicians a clearer picture of how tumors are responding to treatment.
Monarch butterflies that migrate long distances have evolved significantly larger and more elongated wings than their stationary cousins, differences that are consistent with traits known to enhance flight ability in other migratory species.
Researchers have shown that closing fishing zones in the ocean has a beneficial effect on Cape penguins, an endangered species endemic to Southern Africa, which feeds exclusively on fish.
Mathematicians have developed a computer application that estimates the magnitude of natural disasters and helps NGOs in the decision making process. The researchers have also presented an on-site humanitarian aid distribution model. Both could have been applied in the case of the recent Haiti...
Why do people with fragile X syndrome, a genetic defect that is the best-known cause of autism and inherited mental retardation, recoil from hugs and physical touch? New research has found in fragile X syndrome there is delayed development of the sensory cortex, the part of the brain that responds to touch, according to a study from Northwestern University. This delay may trigger a domino effect...
