You recently saw how a build-up of microbes in bagpipes recently doomed a Scottish man. That could apply to all wind instruments, and a U.S. Food and Drug Administration microbiologist warns that several species of bacteria found in smokeless tobacco products have been associated with opportunistic infections.

Obviously that doesn't mean they caused them but associations are important in making health policy, and alternatives to cigarette smoking, in the interests of harm reduction and smoking cessation, are controversial, with the U.S. government being squarely against them, a legacy of the 'quit or die' mentality that has keep cigarette smoking as (not very) popular that it is.

A type of sugar found naturally in some women's breast milk may protect new born babies from infection with a potentially life threatening bacterium called Group B streptococcus. These bacteria are a common cause of meningitis in new borns and the leading cause of infection in the first three months of life in the UK and globally.

 The small study involved 183 women in The Gambia and published in the journal Clinical and Translational Immunology, suggests a sugar found in some women's breast milk protect babies against the bacteria. 

It's summertime, and the fields of Yolo County, Calif., are filled with rows of sunflowers, dutifully facing the rising sun.

At the nearby University of California, Davis, plant biologists have now discovered how sunflowers use their internal circadian "clocks," acting on growth hormones, to follow the sun during the day as they grow.

"It's the first example of a plant's clock modulating growth in a natural environment, and having real repercussions for the plant," said Stacey Harmer, a plant biologist at UC Davis and senior author of a paper reporting the discovery published this week in the journal Science.

Are e-cigarettes harmful? It's probably the wrong question. Caffeine is quite toxic but the Centers for Disease Control doesn't promote concern about Red Bull energy drinks. What is known to be harmful, the weight of evidence is indisputable, are cigarettes. With 200 toxic chemicals being inhaled into lungs, they are linked to every form of cancer and disease for good reason.

While preventing cancer is impossible, what will be possible soon is making cancer far more manageable, like diabetes, and treatment far less debilitating. A new drug delivery system called a "metronomic dosage regimen," uses significantly lower doses of chemotherapeutic drugs but at more frequent time intervals. This would have multiple goals of killing cancer cells, creating a hostile biological environment for their growth, reducing toxicity from the drug regimen and avoiding the development of resistance to the cancer drugs being used.

Lake Nona, Fla., August 25, 2016 -- Scientists at the Sanford Burnham Prebys Medical Discovery Institute (SBP) have identified a previously unknown way that stress hormones (glucocorticoids) shut off genes in the liver to help the body adapt to the fasting state. The study, published today in Cell Metabolism, describes an obscure protein, SETDB2, that's increased during times of fasting and alters the genome to help turn on genes needed to adjust to the absence of food.
