Epidemiologists at University of California, San Diego School of Medicine report that persons residing at higher latitudes, with lower sunlight/ultraviolet B (UVB) exposure and greater prevalence of vitamin D deficiency, are at least two times at greater risk of developing leukemia than equatorial populations.
Scientists from the Mechanobiology Institute, Singapore at the National University of Singapore have discovered the universal building blocks that cells use to form initial connections with the surrounding environment. These early adhesions have a consistent size of 100 nanometres, are made up of a cluster of around 50 integrin proteins and are the same even when the surrounding surface is hard or soft. Deciphering the universal nature of adhesion formation may reveal how tumour cells sense and migrate on surfaces of different rigidity, which is a hallmark of metastasis, the devastating ability of cancer to spread throughout the body.
An NCAR-led team of scientists is launching a series of research flights this month over the remote Southern Ocean in an effort to better understand just how much carbon dioxide the icy waters are able to lock away.

In polluted environments, diesel fumes may be reducing the availability of almost half the most common flower odours that bees use to find their food, research has found.
The effect of radiation exposure related to the nuclear accidents that took place in Fukushima, Japan, and Chernobyl, Ukraine on thyroid cancer risk, whether dietary habits influence the risk of developing thyroid cancer, and recent study results with a triiodothyronine (T3) analog in an uncommon form of thyroid disease are all topics featured in oral presentations delivered at the 15th International Thyroid Congress, hosted by the American Thyroid Association, October 18-23, 2015, in Orlando (Lake Buena Vista), Florida.

A team of researchers at Wayne State University have discovered that mothers with high levels of lead in their blood not only affect the fetal cells of their unborn children, but also their grandchildren. Their study, Multigenerational epigenetic inheritance in humans: DNA methylation changes associated with maternal exposure to lead can be transmitted to the grandchildren, was published online this week in Scientific Reports.
Today, the Environmental Protection Agency announced a lower National Ambient Air Quality Standard for ozone of 70 parts per billion (ppb)/8-hours daily maximum concentration. While today’s announcement represents progress towards improving our nation’s air quality and the overall health of the American public, the selection of 70 ppb ignores the compelling evidence that a more protective standard is needed.

A new UW study that tested 65 wines from America's top four wine-producing states -- California, Washington, New York and Oregon -- found all but one have arsenic levels that exceed U.S. drinking water standards. But health risks from that naturally-occurring toxic element depend on how many other high-arsenic foods and beverages, such as apple juice, rice, or cereal bars, an individual person eats.
A study led by U geography professor Kathryn Grace found that a pregnant woman's exposure to reduced precipitation and an increased number of hot days result in lower birth weight. A first of its kind, the study is the first time researchers utilized fine-resolution precipitation and temperature data alongside birth data to analyze how weather impacts birth weight. The study examined 70,000 births across two decades in 19 African countries.
