Researchers uncover how phytoplankton release powerful toxins into environment

Each year, phytoplankton blooms known as "red tides" kill millions of fish and other marine organisms and blanket vast areas of coastal water around the world. Though the precise causes of red tides remain a mystery, a team of researchers in the United States and Spain has solved one of the main riddles about these ecological disasters by uncovering the specific mechanism that triggers phytoplankton to release their powerful toxins into the environment.

MRSA strain in food animals concerns experts

The strain of staph, known as methicillin-resistant Staphylococcus aureus, or MRSA CC398, most often infects farm workers who come in contact with infected pigs, turkeys, or cows. Now the strain of bacteria has been found in about half of meat samples taken throughout the country. The researchers say that the indiscriminate use of antibiotics in livestock used for food is to blame for the infection's drug resistance.

More toxic aldehydes found in reheated sunflower and linseed oil

Researchers from the University of the Basque Country (UPV/EHU, Spain) have been the first to discover the presence of certain aldehydes in food, which are believed to be related to some neurodegenerative diseases and some types of cancer. These toxic compounds can be found in some oils, such as sunflower oil, when heated at a suitable temperature for frying.

Researchers identify potent regulator of sensitivity to insulin

Researchers at Washington University School of Medicine in St. Louis have identified a potent regulator of sensitivity to insulin, the hormone that controls blood sugar levels. The new findings may help scientists find better treatments for type 2 diabetes, obesity and other health problems caused by the body's inability to properly regulate blood sugar.

Oxygen deprivation disrupts insulin and glucose regulation in rat pups

Premature infants' immature lungs and frequent dips in blood pressure make them especially vulnerable to a condition called hypoxia in which their tissues don't receive enough oxygen, sometimes leading to permanent brain damage. New animal research suggests that a common practice in caring for these babies might in fact exacerbate this condition, increasing the chances for long-term neurological deficits.

Women with higher mammographic density more likely to develop breast cancer

A new study analyses the influence that certain birth and infancy characteristics have on mammographic density - an important indicator of breast cancer risk. The results reveal that women born to mothers aged over 39 years and women who were taller and thinner than the average girl prior to puberty have a higher breast density. This brings with it an increased risk of developing breast cancer.

Injectable progesterone contraceptives may be associated with poor periodontal health, according to research in the Journal of Periodontology. The study found that women who are currently taking depotmedroxyprogesterone acetate (DMPA) injectable contraceptive, or have taken DMPA in the past, are more likely to have indicators of poor periodontal health, including gingivitis and periodontitis, than women who have never taken the injectable contraceptive.
