Researchers at University of California, San Diego School of Medicine report that higher levels of vitamin D - specifically serum 25-hydroxyvitamin D - are associated with a correspondingly reduced risk of cancer. The findings are published in the April 6, online issue of PLOS ONE.

"We have quantitated the ability of adequate amounts of vitamin D to prevent all types of invasive cancer combined, which had been terra incognita until publication of this paper," said Cedric Garland, DrPH, adjunct professor in the UC San Diego School of Medicine Department of Family Medicine and Public Health and member of Moores Cancer Center at UC San Diego Health.

BUFFALO, N.Y. - Rapidly advancing technology has created ever more realistic video games. Images are sharp, settings have depth and detail, and the audio is crisp and authentic. At a glance, it appears real. So real, that research has consistently found that gamers feel guilty committing unjustified acts of violence within the game.

Now, a new University at Buffalo-led study suggests that the moral response produced by the initial exposure to a video game decreases as experience with the game develops.

The findings provide the first experimental evidence that repeatedly playing the same violent game reduces emotional responses -- like guilt -- not only to the original game, but to other violent video games as well.

In a research report appearing in the April 2016 issue of The FASEB Journal, scientists show that a cannabinoid receptor, called "CB2," helps regulate the creation of sperm. Not only does this provide more evidence that marijuana can disrupt fertility in males, but it also suggests a therapeutic strategy for treating male infertility.

WASHINGTON, D.C., April 8, 2016 -- University of Houston physicists report finding major theoretical flaws in the generally accepted understanding of how a superconductor traps and holds a magnetic field. More than 50 years ago, C.P. Bean, a scientist at General Electric, developed a theoretical explanation known as the "Bean Model" or "Critical State Model."

The basic property of superconductors is that they represent zero "resistance" to electrical circuits. In a way, they are the opposite of toasters, which resist electrical currents and thereby convert energy into heat. Superconductors consume zero energy and can store it for a long period of time. Those that store magnetic energy --known as "trapped field magnets" or TFMs -- can behave like a magnet.

Cardiovascular disease from atherosclerosis is one of the most common causes of death worldwide. Inflammation plays a crucial role in atherosclerosis and cholesterol crystals are considered to be early triggers in the development of the disease.

An international team has now found that cyclodextrin dissolves cholesterol crystals and reduces atherosclerotic plaques. This is a promising therapeutic approach for treating atherosclerosis. Their find was published in Science Translational Medicine.

Coeliac disease is a chronic, immunological disease that is manifested as intolerance to gluten proteins present in wheat, rye and barley. This intolerance leads to an inflammatory reaction in the small intestine that hampers the absorption of nutrients. The only treatment is a strict, life-long, gluten-free diet.
