CSHL scientists discover a new way in which epigenetic information is inherited
Hereditary information flows from parents to offspring not just through DNA but also through the millions of proteins and other molecules that cling to it.   view more (2008-12-01)

Prostate cancer spurs new nerves
Prostate cancer - and perhaps other cancers - promotes the growth of new nerves and the branching axons that carry their messages, a finding associated with more aggressive tumors, said researchers from Baylor College of Medicine in the first report of the phenomenon that appears today in the... view more (2008-12-01)

Adult brain neurons can remodel connections
Overturning a century of prevailing thought, scientists are finding that neurons in the adult brain can remodel their connections.   view more (2008-11-25)

Superglue from the sea
Sandcastle worms live in intertidal surf, building sturdy tube-shaped homes from bits of sand and shell and their own natural glue.   view more (2008-11-25)

Scripps Research Scientists Shed Light on How DNA Is Unwound So That Its Code Can Be Read
Researchers at The Scripps Research Institute have figured out how a macromolecular machine is able to unwind the long and twisted tangles of DNA within a cell's nucleus so that genetic information can be "read" and used to direct the synthesis of proteins, which have many specific... view more (2008-11-25)

Scientists Present 'Moving' Theory Behind Bacterial Decision-Making
Biochemists at North Carolina State University have answered a fundamental question of how important bacterial proteins make life-and-death decisions that allow them to function, a finding that could provide a new target for drugs to disrupt bacterial decision-making processes and related diseases.   view more (2008-11-25)

Researchers Shed Light on Evolution of Gene Regulation
Scientists at Penn State have shed light on some of the processes that regulate genes -- such as the processes that ensure that proteins are produced at the correct time, place, and amount in an organism -- and they also have shed light on the evolution of the DNA regions that regulate genes.   view more (2008-11-25)

Misreading of damaged DNA may spur tumor formation
The DNA in our cells is constantly under assault from oxygen, the sun's radiation and environmental stresses. Most of the time, our cells can repair the damage before it gets copied into a permanent mutation that could lead to cancer.   view more (2008-11-21)

Memory mission explores new territory in neuroscience
Astrophysicists peer into the far corners of deep space for dark matter, but for neuroscientists at the Queensland Brain Institute (QBI) exploring the unknown is much closer to home.   view more (2008-11-21)

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)

First Trial in the U.S. to Treat Both Ischemic & Non-Ischemic Heart Failure to be Performed by U of U Researchers Using Patient's Own Stem Cells
Researchers at the University of Utah are enrolling people in a new clinical trial that uses a patient's own stem cells to treat ischemic and non-ischemic heart failure.   view more (2008-11-18)

New gene silencing pathway found in plants
Biologists at Washington University in St. Louis have made major headway in explaining a mechanism by which plant cells silence potentially harmful genes.    view more (2008-11-18)

Genetics for personalized coronary heart disease treatment
Identifying a single, common variation in a person's genetic information improves prediction of his or her risk of a heart attack or other heart disease events and thus, choice of the best treatment accordingly, said researchers at Baylor College of Medicine in Houston.   view more (2008-11-12)

SNPs affect folate metabolism in study of Puerto-Rican adults
Researchers at Tufts University have gained further understanding of the genomic basis for altered folate metabolism and the content of uracil in blood DNA.   view more (2008-11-11)

No drop in IQ seen after bypass for child heart surgery
The use of cardiopulmonary bypass does not cause short-term neurological problems in children and teenagers after surgery for less complex heart defects, according to pediatric researchers.   view more (2008-11-11)

OHSU finds association between Epstein-Barr virus, inflammatory diseases of the mouth
Researchers at Oregon Health & Science University's School of Dentistry (www.ohsu.edu/sod) have found that a significant percentage of dental patients with the inflammatory diseases irreversible pulpitis and apical periodontitis also have the Epstein-Barr virus.   view more (2008-11-11)

General anesthesia for hernia surgery in children and risk of later developmental problems
Children under the age of three who had hernia surgery showed almost twice the risk of behavioral or developmental problems later compared to children who had not undergone the surgery, according to a study by researchers at Columbia University Mailman School of Public Health and the College of... view more (2008-11-10)

Yale researchers unravel mystery of brain aneurysms
Yale researchers have taken the first critical steps in unraveling the mysteries of brain aneurysms, the often fatal rupturing of blood vessels that afflicts 500,000 people worldwide each year and nearly killed Vice President-elect Joseph Biden two decades ago.   view more (2008-11-10)

Social interactions can alter gene expression in the brain, and vice versa
Our DNA determines a lot about who we are and how we play with others, but recent studies of social animals (birds and bees, among others) show that the interaction between genes and behavior is more of a two-way street than most of us realize.   view more (2008-11-07)

Washington University scientists first to sequence genome of cancer patient
For the first time, scientists have decoded the complete DNA of a cancer patient and traced her disease - acute myelogenous leukemia - to its genetic roots.   view more (2008-11-06)

DNA provides 'smoking gun' in the case of the missing songbirds
It sounds like a tale straight from "CSI": The bully invades a home and does away with the victim, then is ultimately found out with the help of DNA evidence.   view more (2008-11-05)

'Junk' DNA proves functional
In a paper published in Genome Research on Nov. 4, scientists at the Genome Institute of Singapore (GIS) report that what was previously believed to be "junk" DNA is one of the important ingredients distinguishing humans from other species.   view more (2008-11-05)

Penn Scientists Map Molecular Regulation of Fat-Cell Genetics
A research team led by Mitchell Lazar, MD, PhD, Director of the Institute for Diabetes, Obesity, and Metabolism at the University of Pennsylvania School of Medicine, has used state-of-the-art genetic technology to map thousands of positions where a molecular "master regulator" of fat-cell... view more (2008-11-05)

Moms' smoking linked to increased risk of birth defects
Babies whose mothers smoked during pregnancy were more than twice as likely to have a cleft palate or lip as those whose mothers didn't, according to research results released today.   view more (2008-11-05)

New method provides panoramic view of protein-RNA interactions in living cells
DNA, it has turned out, isn't all it was cracked up to be. In recent years we learned that the molecule of life, the discovery of the 20th century, did not -- could not -- by itself explain the huge differences in complexity between a human and a worm.   view more (2008-11-03)
