You won't see these in a Whole Foods any time soon, but science has a way to improve the microbiological safety of meat; antimicrobial agents incorporated into edible films. As a bonus, they seal in flavor, freshness and color, according to researchers in Penn State's College of Agricultural Sciences.

Using films made of pullulan -- an edible, mostly tasteless, transparent polymer produced by the fungus Aureobasidium pulluns -- researchers evaluated the effectiveness of films containing essential oils derived from rosemary, oregano and nanoparticles against foodborne pathogens associated with meat and poultry.

While smokers are the primary addictive personality it remains okay to demonize, obesity is not far behind. 

And if smokers tried to quit before and gained weight, they are less likely to try again, according to scholars at Penn State College of Medicine. 

Weight gain is a predictable occurrence for smokers who have recently quit. Within the first year after quitting, people  gain from eight to 14 pounds on average. Some smokers report that they keep smoking simply because they do not want to gain weight from quitting. 

In the 1950s and 1960s, pregnant women with morning sickness were often prescribed thalidomide. Shortly after the medicine was released on the market, a reported 10,000 infants were born with an extreme form of the rare congenital phocomelia syndrome, which caused death in 50 percent of cases and severe physical and mental disabilities in others.

Although various factors are now known to cause phocomelia, the prominent roots of the disease can be found in the use of the drug thalidomide.  It ignited the anti-pharmaceutical cultural firestorm that still burns today.

Rapidly aging mice fed an experimental drug lived more than four times longer than a control group, and their lungs and vascular system were protected from accelerated aging, according to a new study.

The reason is a protein's key role in cell and physiological aging. The experimental drug inhibits the protein's effect and prolonged the lifespan in a mouse model of accelerated aging. 

This is a completely different target and different drug than anything else being investigated for potential effects in prolonging life and the experimental drug is in the early stages of testing, they note in Proceedings of the National Academy of Sciences.

Aquatic algae can sense and adapt to changing light conditions in lakes and oceans, making them able to use a wide range of color, according to a new paper.

Phytochromes are the eyes of a plant, allowing it to detect changes in the color, intensity, and quality of light so that the plant can react and adapt. Typically about 20 percent of a plant's genes are regulated by phytochromes and the phytochromes use bilin pigments that are structurally related to chlorophyll, the molecule that plants use to harvest light and use it to turn carbon dioxide and water into food.

In a Twitter age, one where mainstream media desperately needs to keep people watching and reading, every event is magnified. A tropical storm that hit New York City was transformed into a Superstorm and a drought in the West is a harbinger of global warming that will crack the planet.
