A new study from Tel Aviv University, Cornell University and the Albert Einstein College of Medicine reveals genetic proof of the Jewish roots of the Bene Israel community in the western part of India. They have always considered themselves Jewish.

"Almost nothing is known about the Bene Israel community before the 18th century, when Cochin Jews and later Christian missionaries first came into contact with it," says first author Yedael Waldman of both TAU's Department of Molecular Microbiology and Cornell's Department of Biological Statistics and Computational Biology. "Beyond vague oral history and speculations, there has been no independent support for Bene Israel claims of Jewish ancestry, claims that have remained shrouded in legend."

New research from Denmark involving more than 100,000 individuals suggests that the excess risk of premature death associated with obesity has decreased over the past 40 years. All-cause mortality was higher in obese individuals than in normal weight individuals in 1976-78, but not in 2003-13.

Many try to lose weight to avoid diabetes and cardiovascular disease and hopefully live longer. This is often driven by recommendations from health care authorities and is further supported by the media and not least, by commercials often presenting normal weight or even thin people as ideal humans.

Roses are red, violets are blue. Everybody knows that, but what makes them so? Although plant breeders were aware of some of the genes involved, there was as yet no quantitative study of how pigment turns a flower red, blue or yellow. Casper van der Kooi conducted just such a study, combining biology and physics.

A new claims the epigenetics of lactose intolerance may provide an approach to understanding schizophrenia - perhaps because both lactose intolerance and schizophrenia are inherited and neither condition emerges in the first years of life and in a booming fad like epigenetics, that is all you need. 

More than 65 per cent of adults worldwide are lactose intolerant and cannot process the milk sugar lactose. Lactose intolerance is influenced by one gene, which determines if a person will lose the ability to process lactose over time. More specifically, those with some variants of this gene will gradually produce less lactase, the enzyme that breaks down lactose, as they age.

When does free speech become important? In the halls of academia, it often comes down along political and cultural lines. An endorsement of business mogul Donald Trump leaves academics and students running for a safe speech while a professor bullying a journalism student claims she was oppressed.

When academics do choose to litigate speech disputes with colleges and universities, they end up losing nearly three-quarters of the time, and Michael LeRoy, a professor of labor and employment relations at
University of Illinois
says that is a sign of growing tension between academic freedom and campus speech codes, without recognizing that these issues only go to action when they are the most flagrant sort of violation.

San Jose, Calif., May 10, 2016 -- A team of more than 80 mathematicians from 12 countries has begun charting the terrain of rich, new mathematical worlds, and sharing their discoveries on the Web. The mathematical universe is filled with both familiar and exotic items, many of which are being made available for the first time. The "L-functions and Modular Forms Database," abbreviated LMFDB, is an intricate catalog of mathematical objects and the connections between them. Making those relationships visible has been made possible largely by the coordinated efforts of a group of researchers developing new algorithms and performing calculations on an extensive network of computers.
