Oregon researchers discover a mechanism leading to cleft palate
By creating a genetic mutation in zebrafish, University of Oregon scientists say they've discovered a previously unknown mechanism for cleft palate, a common birth defect in humans that has challenged medical professionals for centuries.   view more (2008-02-12)

Hotspots found for chromosome gene swapping
Crossovers and double-strand DNA breaks do not occur randomly on yeast chromosomes during meiosis, but are greatly influenced by the proximity of the chromosome's telomere, according to research in the laboratory of Whitehead Fellow Andreas Hochwagen.   view more (2007-11-30)

Scientists fashion semiconductors into flexible membranes
University of Wisconsin-Madison researchers have demonstrated a way to release thin membranes of semiconductors from a substrate and transfer them to new surfaces-an advance that could unite the properties of silicon and many other materials, including diamond, metal and even plastic.   view more (2006-04-10)

Microarray analysis improves prenatal diagnosis
A "chip" or array that can quickly detect disorders such as Down syndrome or other diseases associated with chromosomal abnormalities proved an effective tool in prenatal diagnosis in a series of 300 cases at Baylor College of Medicine, said researchers in a report that appears in the... view more (2008-11-18)

Regulatory pathway in brain development possible basis for malformations
Researchers at the University of California, San Diego (UCSD) School of Medicine have identified a genetic regulator of brain development that sheds new light on how immature neural cells choose between proliferation and differentiation.   view more (2006-12-05)

Rensselaer researchers create tiny magnetic diamonds on the nanoscale
Diamonds have always been alluring, but now a team of scientists has made them truly magnetic - on the nanoscale.   view more (2005-09-13)

Congenital heart disease increasingly more common in adults, children
The prevalence of congenital heart disease (CHD) has increased strikingly in adults and children in a new population study, researchers reported in Circulation: Journal of the American Heart Association.   view more (2007-01-09)

UF scientists discover evolutionary origin of fins, limbs
Evolutionarily speaking, the genetic instructions used to construct and position our limbs were being perfected more than half a billion years ago in fishes, not along the sides of the body where the fins that preceded human arms and legs sprouted, but at the midline that runs along the backbone... view more (2006-07-27)

Smoking While Pregnant Causes Finger, Toe Deformities
Women have yet another reason to stop smoking while pregnant. In the largest study of its kind, plastic surgeons found smoking during pregnancy significantly elevates the risk of having a child with excess, webbed or missing fingers and toes.   view more (2006-01-06)

MIT material puts new spin on electronics
Researchers at MIT's Francis Bitter Magnet Lab have developed a novel magnetic semiconductor that may greatly increase the computing power and flexibility of future electronic devices while dramatically reducing their power consumption.   view more (2006-05-25)

Nanotube, heal thyself
Pound for pound, carbon nanotubes are stronger and lighter than steel, but unlike other materials, the miniscule cylinders of carbon - which are no wider than a strand of DNA - remain remarkably robust even when chunks of their bodies are blasted away with heat or radiation.   view more (2007-02-16)

UT-Houston's Northrup and Colleagues Uncover Genetic Link to Spina Bifida
Researchers at The University of Texas Medical School at Houston have discovered an association between genes regulating glucose metabolism and spina bifida. The decade-long study looked at more than 1,500 DNA samples from parents and their children with that birth defect.   view more (2007-12-19)

Mice provide important clues to obsessive-compulsive disorder
Mice born without a key brain protein compulsively groom their faces until they bleed and are afraid to venture out of the corner of their cages.   view more (2007-08-23)

Study finds HIV protease inhibitor drugs may adversely affect the scaffolding of the cell nucleus
UCLA scientists, along with collaborators from Purdue University, have demonstrated that HIV protease inhibitors - crucial drugs for HIV treatment - block a cellular enzyme important for generating the structural scaffolding for the cell nucleus.   view more (2007-07-17)

Lost in the labyrinth
Blood cells have limited lifespans, which means that they must be continually replaced by calling up reserves, and turning these into the blood cell types needed by the body.   view more (2006-09-05)

Possible to detect causes of autism in over a third of cases
It may be possible to find the causes for autism in over a third of cases, suggests research in the Journal of Medical Genetics. And these are likely to include a range of factors.   view more (2002-03-11)

7 years without a nose
Patients whose nose has been destroyed by a tumor or injury carry a severe psychological and social burden. Esthetic reconstruction ranges among the most challenging tasks in plastic surgery.   view more (2008-11-07)

Extra-large 'atoms' allow Penn physicists to solve the riddle of why things melt
Physicists at the University of Pennsylvania have experimentally discovered a fundamental principal about how solid materials melt. Their studies have shown explicitly that melting begins at defects within the crystalline structure of solid matter, beginning along the cracks, grain boundaries and... view more (2005-07-01)

Nottingham biosciences million pound injection
Nottingham's strength as a UK Science City is further underlined today, with news that the Wellcome Trust, the UK's largest medical research charity, has awarded almost £1 million to an innovative biosciences company.   view more (2007-07-30)

Regulatory T cells require WASp if they are to prevent self-destruction
In humans, mutation of the gene encoding a protein known as WASp leads to susceptibility to infections and systemic autoimmunity.   view more (2007-01-12)

Nanoengineered barrier invented to protect plastic electronics from water degradation
A breakthrough barrier technology from Singapore A*STAR's Institute of Materials Research and Engineering (IMRE) protects sensitive devices like organic light emitting diodes (OLEDs) and solar cells from moisture 1000 times more effectively than any other technology available in the market, opening... view more (2008-04-29)

Discovery of 'hidden' quantum order improves prospects for quantum super computers
An international team of scientists, including several at The Johns Hopkins University, has detected a hidden magnetic "quantum order" that extends over chains of nearly 100 atoms in a material that is otherwise magnetically disordered.   view more (2007-07-27)

Genetic research unveils common origins for distinct clinical diagnoses
Researchers at Johns Hopkins have discovered that two clinically different inherited syndromes are in fact variations of the same disorder. Reporting in the April issue of Nature Genetics, the team suggests that at least for this class of disorders, the total number and "strength" of... view more (2008-03-10)

Hopkins researchers piece together gene 'network' linked to schizophrenia
Reporting this week in the Archives of General Psychiatry, researchers at the Johns Hopkins University School of Medicine have uncovered for the first time molecular circuitry associated with schizophrenia that links three previously known, yet unrelated proteins.   view more (2008-09-03)

Alcohol consumption can cause too much cell death, fetal abnormalities
The initial signs of fetal alcohol syndrome are slight but classic: facial malformations such as a flat and high upper lip, small eye openings and a short nose.   view more (2008-08-26)
