Giant undersea microbial mat among discoveries revealed by marine life census

Posted: 17 Apr 2010 09:00 PM PDT

Explorers are puzzling out nature's purpose behind the discovery of an astonishing variety of tiny ocean creatures like microbes and zooplankton animals, which together underpin almost all other life on Earth.

Factors contributing to health disparities among minority women: Unique breast cancer experience in the Inland Empire, CA

Posted: 17 Apr 2010 09:00 PM PDT

In the Inland Empire locale of Southern California, failure to detect breast cancer in its early, more treatable stages is common among black women, and researchers have discovered that the cause may be a combination of incidence and mortality patterns, poverty, and a lack of medical insurance and education.

Impact of race and health insurance on delays in breast cancer diagnosis and treatment in the District of Columbia

Race may play a larger role than previously thought when it comes to optimal diagnosis and treatment of black women with breast cancer.

Secondhand tobacco smoke in bars and restaurants in Guatemala: Before and after indoor smoking ban evaluation

Posted: 17 Apr 2010 09:00 PM PDT

A smoking ban in bars and restaurants in Guatemala effectively reduced nicotine levels in these places, but not as much as hoped, which suggests the need for more rigorous enforcement.

United States (U.S.)-Mexico border Latinas: breast cancer knowledge, attitudes and factors associated with early detection practices

Latina women who reside on either side of the U.S.-Mexico border are a study in contrasts when it comes to breast cancer screening.

A brain-recording device that melts into place

Posted: 17 Apr 2010 09:00 PM PDT

Scientists have developed a brain implant that essentially melts into place, snugly fitting to the brain's surface. The technology could pave the way for better devices to monitor and control seizures, and to transmit signals from the brain past damaged parts of the spinal cord.

Performing complex tasks under stress activates hidden neuronal circuit in brain

Posted: 17 Apr 2010 09:00 PM PDT

Did you ever wonder how you are able to perform complex tasks -- even under stress? And how do emotions and memories mold your ability to live your everyday lives? Studies of a microscopic worm show how physiological detection of stress results in activation of a hidden neuronal circuit. It is suggested that such circuits form part of an escape response that enables animals to sense their environment and adapt their behavior under unfavorable conditions.

You had me at hello: Frisky yeast know who to 'shmoo' after two minutes

Posted: 17 Apr 2010 09:00 PM PDT

Yeast cells decide whether to have sex with each other within two minutes of meeting, according to new research. One of the authors of the study says the new insights into how yeast cells decide to mate could be helpful for researchers looking at how cancer cells and stem cells develop.

Fundamental causes of colorectal cancer outcomes

Socioeconomic status plays a role in colorectal cancer mortality rates by hindering health care interventions and/or restricting patient access to care, according to results of a retrospective cohort study.

Vitamin and calcium supplements may reduce breast cancer risk

Vitamins and calcium supplements appear to reduce the risk of breast cancer, according to new research.

Routine breast cancer biopsy might predict lymph node cancer spread

Posted: 17 Apr 2010 09:00 PM PDT

Predicting breast cancer spread from a sentinel lymph node removed during surgery is a hit or miss affair, say researchers: there are still many false negatives, which means the node, when analyzed under a microscope, appears clean of cancer cells, but metastasis can still occur in the patient. The sentinel node is the first lymph node in the axilla that cancer spreads to.
