Why we learn from our mistakes
Psychologists from the University of Exeter have identified an

Cell receptor may lead to new 'biomarker' for pancreatic cancer
A research team led by University of Cincinnati scientists has identified a potential biological target for pancreatic cancer, a finding they say could help scientists better understand -- and eventually treat -- the disease that kills more than 33,000 people each year.

Doing nature one better: Expanding the genetic code in living mammalian cells
Researchers at the Salk Institute for Biological Studies have developed a novel strategy to expand the natural repertoire of 20 amino acids in mammalian cells, including neurons, and successfully inserted tailor-made amino acids into proteins in these cells.

Early fire risk for mountains near Los Angeles
Researchers at the University of Utah and elsewhere developed a new way to predict when vegetation dries to the point it is most vulnerable to large fires in the Santa Monica Mountains near Los Angeles.

Combination of bronchoscopic techniques improves diagnostic yield in peripheral lung lesions
The combined use of two minimally invasive techniques -- endobronchial ultrasound (EBUS) and electromagnetic navigation bronchoscopy (ENB) -- in the diagnosis of peripheral lung lesions has been shown to be more effective than either procedure alone and does not compromise patients' safety, according to a new study.

Exposure to cats increases bronchial responsiveness in people without specific cat allergy
Researchers in the United Kingdom have found that increased exposure to cat allergen is associated with greater bronchial responsiveness (BR) in people with certain common allergies, even if they are not specifically allergic to cats.

What happened before the Big Bang?
New discoveries about another universe whose collapse appears to have given birth to the one we have today are in a research paper to be published on July 1, 2007.

New method for reading DNA sheds light on basis of cell identity
By using a new kind of genomic technology, a new study unveils a special code -- not within DNA, but within the so-called

Extracting eggs from pre-pubertal cancer patients brings hope for future fertility
Scientists in Israel have been able to obtain and freeze eggs from the ovarian tissue of girls as young as 5 years old, the 23rd Annual Conference of the European Society of Human Reproduction and Embryology will hear on Tuesday, July 3.

Allergy molecule identified
A vital molecule for resistance to food allergy has been identified offering a potential target for therapy.

Stressed-out African naked mole-rats may provide clues about human infertility
Naked mole-rats could shed light on stress-related infertility in humans, the 23rd Annual Meeting of the European Society of Human Reproduction and Embryology will hear.

Scientists discover key to manipulating fat
In what they call a

Suicide attempts decline after depression treatment
In a study of more than 100,000 patients treated for depression, suicide attempts declined during the first month of treatment -- whether that treatment consisted of medication, psychotherapy, or both.

How we can stop stress from making us obese
New findings on the mechanisms that trigger stress-induced obesity, published today in Nature Medicine online, could offer hope to millions.

Translating form into function
In the last 40 years, scientists have perfected ways to determine the knot-like structure of enzymes, but they've been stumped trying to translate the structure into an understanding of function -- what the enzyme actually does in the body. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
