PHILADELPHIA--(July 7, 2016)--As the powerhouse of the cells, mitochondria are critical for every organism because of their role in producing energy while also controlling survival, but how they function in cancer is still not completely known. This is particularly important because, in general, tumor cells proliferate more than normal tissues, and scientists have speculated that mechanisms that preserve mitochondrial function are responsible for supporting tumor expansion.

CINCINNATI -- More women may be smoking and exposed to nicotine during pregnancy than previously thought, according to a new study by researchers from Cincinnati Children's Hospital Medical Center in collaboration with Cradle Cincinnati.

The study reveals a significant gap between the number of local, pregnant mothers who report smoking during pregnancy and the number who test positive for nicotine exposure.

7 July 2016 - New research shows that patient-derived cancer cell lines harbour most of the same genetic changes found in patients' tumours, and could be used to learn how tumours are likely to respond to new drugs. The findings, published in Cell, will help to increase the success rate for developing new, more personalised cancer treatments.

Biomass is one of the main sources of energy and heat in the field of renewable energy production: it is any type of non-fossil organic matter, such as living plants, timber, agricultural and livestock waste, wastewater, solid urban organic waste, etc. The three most developed technologies for obtaining energy from biomass are as follows: pyrolysis (decomposition by heating in the absence of oxygen), gasification (reaction with air, oxygen or a blend of both and conversion into gas) and combustion (decomposition through heating with oxygen). The effectiveness and emission levels of these three processes change depending on the composition of the biomass as well as its properties, the experimental conditions and equipment used.

Jessica Alba's "Honest" company has been criticized for being frauds but it's not alone. Though the variation in cost for sunscreen protection averages well over 3,000, the variation is protection is not very much.

Like with organic food, you don't get what you pay for - unless what you are paying for is self-identification. But no matter what you pay or why you buy, you may not be getting a product that meets the American Academy of Dermatology's guidelines for sunscreens. This was largely due to a lack of water or sweat resistance, according to a new Northwestern Medicine study.

Beer is the world's most commonly fermented beverage and lager beer commands 94 percent of the global market. Making the beer possible is a biological oddity: a hybrid yeast that combines two distinct species and confers the ability to make cold-brewed beer, a product that first emerged 500 years ago in Europe.

 Without question, the domesticated hybrid yeast that gives us lager beer is an organism worth many billions of dollars, but just how Saccharomyces cerevisiae, the well-known domesticated yeast that gives us wine and bread, combined with Saccharomyces eubayanus, a yeast species only recently discovered in nature, to give us the hybrid organism that makes cold-brewed beer remains a mystery.
