Nausea sometimes a red flag for anxiety and depression
People who experience nausea may be suffering from anxiety or depression, possible causes that should be investigated before aggressive treatments are begun for gastrointestinal disorders, according to a new study.

Chemical attraction needed to launch an immune attack
A team led by UCSF scientists has determined how the weapons producers of the immune system - the B cells that make antibodies - find the T cells they must team up with to attack invading pathogens.

Bacteria's iron-absorbing mechanisms may open gates for new types of antibiotics
Researchers at UT Southwestern Medical Center at Dallas have brought to light new information about how bacteria capture iron from the human body, and the work has implications for the design of novel antibiotics.

FUSE returns to full-time science operations
A moribund orbiting observatory that some had given up for dead returned to life early this month thanks to the ingenuity of scientists and engineers who worked round-the-clock hours to give the satellite a new guidance system without ever actually touching it.

'Buried dams' help clean recycled water
Disease-causing microbes can effectively be eliminated from recycled water by storing it underground, new research by CSIRO scientists has found.

Eating breakfast may keep colds & flu at bay
Overall knowledge about the psychology of the common cold has greatly increased in recent years and one of the main findings has been the link between stress and susceptibility to colds.

UCLA scientists, colleagues substantiate biological origin of earliest fossils
UCLA paleobiologist J. William Schopf and colleagues have substantiated the biological origin of the earliest known cellular fossils, which are 3.5 billion years old.

Scientists learn something new about one of the most studied chemical reactions
The simplest and best-studied chemical reaction - the collision of a hydrogen atom H with molecular hydrogen H2 - is still unveiling its mysteries to scientists.

Chimpanzee virus may be key to better vaccines, study shows
Immunologists know that human adenoviruses can be retooled in the laboratory to serve as effective vaccines.

Male virus levels significant in spread of HIV to women
Higher HIV levels among men significantly increase the likelihood they will spread the virus to their female sex partners, according to a cross sectional study conducted by researchers at the Johns Hopkins Bloomberg School of Public Health.

Coffee may help prevent cavities
Coffee might help prevent cavities, according to a study in the Journal of Agricultural and Food Chemistry.

Self-organization of the web and identification of communities
Study finds that the World Wide Web self-organizes into communities which can be efficiently identified based on the link structure of the web.

Prototype detector could identify anthrax quickly
Some deadly things don't deserve 15 minutes of FAME, let alone several hours.

UC Davis mathematician, neuroscientist win Sloan Fellowships
Two new faculty members at the University of California, Davis, neuroscientist Marie Burns and mathematician Alexander Soshnikov, have won prestigious Alfred P.

SFVAMC study explains prostate cancer resistance to hormone therapy
Hormone therapy is often used to treat prostate cancer, but these drugs that mimic the effects of estrogen do not work on many late-stage cancers.

Humans emerged 'out of Africa' again and again
Analyses of recently derived human genetic trees by Alan R.

Hydrogen reaction experiment reaps a surprise
Scientists got a surprise recently when a team of physical chemists at Stanford University studied a common hydrogen reaction.

Stanford's new antigen microarrays open window to better disease screening
Your immune system normally protects against disease, but in some cases - such as with rheumatoid arthritis, lupus, and type-I diabetes - the immune system actually attacks your body.

Molecular researchers to link heart & brain puzzle pieces at La Jolla conference
Topics include the convergence of heart and brain research, the critical shortage of physician-scienctists, and award presentations to prominent scientists and organizations.

Protein associated with lung cancer linked for the first time to head and neck cancer
Researchers from the University of Pittsburgh Cancer Institute are the first to find that the protein gastrin-releasing peptide receptor (GRPR), know to be associated with lung cancer, is linked to the proliferation of squamous cell carcinoma of the head and neck.

Undergrad finds clues to 400-million-year-old mystery
A Johns Hopkins senior from Cherry Hill, N.J., has found potentially decisive evidence in a debate about the identity of one of the first organisms to make the epochal leap from the sea to dry land approximately 400 million years ago.
