ST. LOUIS, Jan. 24, 2013 – A new study published in The Journal of Nutrition demonstrates the benefits of consuming a protein blend for muscle protein synthesis after exercise. This study is a first-of-its-kind, conducted by researchers at the University of Texas Medical Branch, and utilizes the proteins from soy, whey and casein consumed after an acute bout of resistance exercise. These proteins have complementary amino acid profiles and different digestion rates (amino acid release profiles).

Have you ever woken up to a sunny forecast only to get soaked on your way to the office? On days like that it's easy to blame the weatherman.

But BYU mechanical engineering professor Julie Crockett doesn't get mad at meteorologists. She understands something that very few people know: it's not the weatherman's fault he's wrong so often.

According to Crockett, forecasters make mistakes because the models they use for predicting weather can't accurately track highly influential elements called internal waves.

Maternal inflammation during early pregnancy may be related to an increased risk of autism in children, according to new findings supported by the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health. Researchers found this in children of mothers with elevated C-reactive protein (CRP), a well-established marker of systemic inflammation.

ANN ARBOR—Female mice exposed to Bisphenol A through their mother's diet during gestation and lactation were found to be hyperactive, exhibit spontaneous activity and had leaner body mass than those not exposed to the chemical, researchers at the University of Michigan School of Public Health have discovered.

BPA is a chemical most commonly found in the lining of food cans and cash register receipts. It once was in many hard plastic bottles, including baby bottles, but many companies have removed it as concerns about exposure have come to light in recent years.

(Boston) – According to a new study from the Slone Epidemiology Center (SEC) at Boston University, African-American women who reported sexual or physical abuse before age 11 had a greater risk of uterine fibroids in adulthood compared with women who had no such abuse history. The association was strongest for women who experienced sexual abuse.

(MEMPHIS, Tenn. – January 24, 2013) Genome sequencing data once regarded as junk is now being used to gain important clues to help understand disease. The latest example comes from the St. Jude Children's Research Hospital – Washington University Pediatric Cancer Genome Project, where scientists have developed an approach to mine the repetitive segments of DNA at the ends of chromosomes for insights into cancer.

ITHACA, N.Y. – With projections of 9.5 billion people by 2050, humanity faces the challenge of feeding modern diets to additional mouths while using the same amounts of water, fertilizer and arable land as today.

Cornell University researchers have taken a leap toward meeting those needs by discovering a gene that could lead to new varieties of staple crops with 50 percent higher yields.

EAST LANSING, Mich. — Vocabulary instruction in the early years is not challenging enough to prepare students for long-term reading comprehension, argues a study led by a Michigan State University education researcher.

The study, which appears in Elementary School Journal, analyzed commonly used reading curricula in U.S. kindergarten classrooms. It found that, generally, the programs do not teach enough vocabulary words; the words aren't challenging enough; and not enough focus is given to make sure students understand the meaning of the words.

Montreal, January 24, 2013 – People who take immunosuppressive drugs to treat lupus do not necessarily increase their cancer risk according to new research led by scientists at the Research Institute of the McGill University Health Centre (RI-MUHC). This landmark study, which was published in Annals of the Rheumatic Diseases this month, addresses long-standing fears of a link between lupus medication and cancer.

Cancer is thought to arise from DNA damage at fragile sites in the genome. A study published by Cell Press on January 24th in the journal Cell reveals a new class of fragile sites that contributes to DNA alterations in a type of blood cancer called B cell lymphoma The findings could lead to the development of more effective treatments for B cell lymphoma and potentially other cancers.

Scientists at the University of Copenhagen's Center for Healthy Ageing have identified a compound that blocks the expression of a protein without which certain tumours cannot grow. This compound has the potential as an anticancer agent according to the research published in the journal CHBIOL: Chemistry and Biology this week.

Our DNA is constantly under attack from UV light, toxins and metabolic processes. Proteins and enzymes continually repair the damaged DNA. Unrecognized and therefore unrepaired damage to the genetic material, however, accelerates aging and causes cancer and genetic disorders. A team headed by veterinary pharmacologist and toxicologist Hanspeter Nägeli has now discovered that the protein XPD plays a key role in locating damaged DNA.

PITTSBURGH, Jan. 24, 2013 – Researchers at the University of Pittsburgh School of Medicine may have found an "Achilles heel" in a key HIV protein. In findings published online today in Chemistry and Biology, they showed that targeting this vulnerable spot could stop the virus from replicating, potentially thwarting HIV infection from progressing to full-blown AIDS.

New Haven, Conn.–Like organisms, cities need energy, water, and nutrients, and they need to dispose of wastes and byproducts in ways that are viable and sustainable over the long run. This notion of "urban metabolism" is a model for looking systematically at the resources that flow into cities and the wastes and emissions that flow out from them—to understand the environmental impacts of cities and to highlight opportunities for efficiencies, improvements, and transformation.

Researchers from Washington University School of Medicine, St. Louis, show that reservoirs of uropathogenic E. coli within the bladder exist in higher numbers post-menopause than pre-menopause in a mouse model, a finding that could help explain the greater prevalence of urinary tract infections in post-menopausal women. They also found that estrogen supplementation reduced the numbers of such reservoirs dramatically. The research was published online ahead of print in the journal Infection and Immunity.
