DENVER – Lung cancer is one of the most common primary cancers that cause leptomeningeal carcinomatosis (LMC), when cancer spreads to the membranes surrounding the spinal cord and brain. Cases of LMC have increased because of the improved survival of lung cancer patients with the help of new advances in treatment. This is the type of cancer diagnosis facingValerie Harper, who played Rhonda on "The Mary Tyler Moore Show."

BOSTON — A passing remark launched the project that will be described at the Experimental Biology 2013 conference in Boston on Monday. A poster, presented by undergraduate Ashley McMichael from Albany State University, has preliminary data that hint that there is an association between a rare pregnancy condition and malaria.

BOSTON — Researchers from Boston University School of Medicine have discovered that eating mushrooms containing vitamin D2 can be as effective at increasing and maintaining vitamin D levels (25–hydroxyvitamin D) as taking supplemental vitamin D2 or vitamin D3.

BOSTON — When the space shuttle Atlantis touched down in the summer of 2011 at Cape Canaveral, closing the book on the U.S. shuttle program, a team of U.S. Army researchers stood at the ready, eager to get their gloved hands on a small device in the payload that housed a set of biological samples. On Monday, April 22, at the Experimental Biology 2013 conference in Boston, the team will present the results of nearly two years' worth of study on those samples, results that shed light on how the human immune system responds to stress and assaults while in space – and maybe here on Earth.

(Boston)—Researchers from Boston University School of Medicine (BUSM) have discovered that eating mushrooms containing Vitamin D2 can be as effective at increasing and maintaining vitamin D levels (25–hydroxyvitamin D) as taking supplemental vitamin D2 or vitamin D3. These findings will be presented at the American Society for Biochemistry and Microbiology annual meeting in Boston on April 22 and also concurrently appear in Dermato-Endocrinology on line open access.

SALT LAKE CITY—Researchers from Huntsman Cancer Institute (HCI) at the University of Utah have developed a novel and powerful technique to identify the targets for a group of enzymes called RNA cytosine methyltransferases (RMTs) in human RNA. They applied their technique to a particular RMT, NSUN2, which has been implicated in mental retardation and cancers in humans, finding and validating many previously unknown RMT targets—an indication of the technique's power. The research results were published online in the journal Nature Biotechnology on April 21.

Child sponsorship is a leading form of direct aid from households in wealthy countries to children in developing countries, with approximately 3.39 billion dollars spent to sponsor 9.14 million children internationally. A new study to be published in the Journal of Political Economy shows international child sponsorship to result in markedly higher rates of schooling completion and substantially improved adult employment outcomes.

HOUSTON -- (April 22, 2013) -- Individual freedom and social responsibility may sound like humanistic concepts, but an investigation of the genetic circuitry of bacteria suggests that even the simplest creatures can make difficult choices that strike a balance between selflessness and selfishness.

EAST LANSING, Mich. — College coaches who emphasize their players' academic abilities may be the best defense against the effects of "dumb jock" stereotypes, a Michigan State University study suggests.

Researchers found that student-athletes were significantly more likely to be confident in the classroom if they believed their coaches expected high academic performance, not just good enough grades to be eligible for sports.

The records checked were for native Australian millipede species and were published online by the Global Biodiversity Information Facility, GBIF and the Atlas of Living Australia, ALA. GBIF and ALA obtain most of their records from cooperating museums, but disclaim any responsibility for errors in museum databases, instead warning users that the data may not be accurate or fit for purpose.

Just as humans can follow complex social situations in deciding who to befriend or to abandon, it turns out that animals use the same level of sophistication in judging social configurations, according to a new study that advances our understanding of the structure of animal social networks.

ANN ARBOR, Mich. – Children can get five to 10 colds each year, so it's not surprising that adults often turn to over-the-counter cough and cold medicines to relieve their little ones' symptoms. But a new University of Michigan poll shows that many are giving young kids medicines that they should not use.

Published today, a special issue of the Philosophical Transactions of The Royal Society – Biological Sciences, addresses a major challenge facing our society: feeding a global population that is simultaneously growing and increasing its per capita food consumption, while preventing widespread ecological and social impoverishment.

TORONTO, April 22, 2013--Academic medical centres invest considerable time, money and other resources in leadership training programs, yet there is no evidence such programs work, a new study has found.

In particular, researchers led by Dr. Sharon Straus at St. Michael's Hospital said they could not determine whether participation in these leadership programs addresses the "paucity of women leaders" in faculty positions at teaching hospitals or which components of leadership training are most effective for women.
