Bacteria may be talking to each other with a contact-dependent language

What if bacteria could talk to each other? What if they had a sense of touch? A new study by researchers at UC Santa Barbara suggests both, and theorizes that such cells may, in fact, need to communicate in order to perform certain functions. The findings appear today in the journal Genes & Development.

Study finds genetic variants that elevate risk for skin lesions in people exposed to arsenic

One of the first large-scale genomic studies conducted in a developing country has discovered genetic variants that elevate the risk for skin lesions in people chronically exposed to arsenic. Genetic changes found near the enzyme for metabolizing the chemical into a less toxic form can significantly increase an individual's risk for developing arsenic-related disease.

Evolutionary forces encourage diversity in the active surfaces of venomous toxins

For snakes, spiders, and other venomous creatures, the "business end," or active part, of a toxin is the area on the surface of a protein that is most likely to undergo rapid evolution in response to environmental constraints, say researchers from Ben Gurion University in Israel.

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.

UM scientists discover high concentrations of BMAA in shark fins

Sharks are among the most threatened of marine species worldwide due to unsustainable overfishing. Sharks are primarily killed for their fins alone, to fuel the growing demand for shark fin soup, which is an Asia delicacy. A new study by University of Miami (UM) scientists in the journal Marine Drugs has discovered high concentrations of BMAA in shark fins, a neurotoxin linked to neurodegenerative diseases in humans including Alzheimer's and Lou Gehrig Disease.

Eating invasive plant pre-adapts bluetongue lizards against cane toad poisons

An invasive plant may have saved an iconic Australian lizard species from death at the hands of toxic cane toads, according to research published in the March issue of The American Naturalist. It's an interesting case of one invasive species preparing local predators for the arrival of another, says Richard Shine, a biologist at the University of Sydney who led the research.

Botox efficacy uncertain in treating migraine says NICE

Botox – used as an anti-wrinkle agent - is unlikely to be recommended for the treatment of chronic migraines on the NHS in England and Wales. According to the National Institute for Health and Clinical Excellence (NICE) draft guidelines there is insufficient evidence that it works.

Breast augmentations most common form of plastic surgery nationwide

Breast augmentations are the most common form of plastic surgery nationwide, according to the American Society of Plastic Surgeons. Loyola University Health System plastic surgeons are seeing similar trends in their practice. The number of women who are getting breast implants also is up from last year. In 2011, 307,180 women nationwide underwent a breast augmentation procedure while 296, 203 women had the same surgery in 2010.

Promising compound may counteract HIV's ability to hijack CD59 protein

One of the frustrations for scientists working on HIV/AIDS treatments has been the human immunodeficiency virus' ability to evade the body's immune system. Now an Indiana University researcher has discovered a compound that could help put the immune system back in the hunt.
