COLUMBIA, Mo. – Breakfast might be the most important meal of the day, but up to 60 percent of American young people consistently skip it. Now, Heather Leidy, an assistant professor in the Department of Nutrition and Exercise Physiology, says eating a breakfast rich in protein significantly improves appetite control and reduces unhealthy snacking on high-fat or high-sugar foods in the evening, which could help improve the diets of more than 25 million overweight or obese young adults in the U.S.

WINSTON-SALEM, N.C. – March 26, 2013 – A proof-of-concept study suggests the possibility of engineering artificial ovaries in the lab to provide a more natural option for hormone replacement therapy for women. In Biomaterials, a team from Wake Forest Baptist Medical Center's Institute for Regenerative Medicine report that in the laboratory setting, engineered ovaries showed sustained release of the sex hormones estrogen and progesterone.
Washington, D.C. (March 26, 2013) – Despite some very high-profile female candidates and elected officials, and what looks like a changing landscape of U.S. politics, a new study conducted by American University professor and director of its Women and Politics Institute Jennifer L. Lawless and Richard L. Fox (Loyola Marymount University) reveals that young women are less likely than young men ever to have considered running for office, to express interest in a candidacy at some point in the future, or to consider elective office a desirable profession.
Research from the University of Iowa suggests that cancer care is more accessible in rural areas than thought, and this increased accessibility should be considered as changes are made in the health care system under the Affordable Care Act.
AURORA, Colo. (March 26, 2013) Adolescent type 1 diabetes patients face greater risk for heart attacks, strokes, blindness and kidney failure later in life if their transition from pediatric to adult care is not carefully managed, two CU researchers have found. The estimated median age at transition to adult care was 20.1 years and 77 percent of individuals with type 1 diabetes had left pediatric care by age 21. The study suggests that without support, they were 2.5 times more likely to have high blood glucose levels when transitioning from pediatric to adult care
PHILADELPHIA — A drug that indirectly impairs the function of several cancer-driving proteins, including anaplastic lymphoma kinase (ALK), may be an effective new treatment for patients with ALK--positive non-small cell lung cancer.
The drug, ganetespib, may also be effective for treating patients who have become resistant to the only FDA-approved targeted therapy for this disease, crizotinib, according to data published in Cancer Discovery, a journal of the American Association for Cancer Research.
PHILADELPHIA — Baldness was associated with an increased risk of prostate cancer among African-American men, and risk for advanced prostate cancer increased with younger age and type of baldness, according to data published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
URBANA – In the United States, only species listed on state or federal noxious weed lists are regulated, and those lists are often biased toward species that affect agricultural crops. Conversely, invasive plant council lists include species that affect natural landscapes but have no regulatory clout. After comparing the lists and how they are created, researchers at the University of Illinois's Energy Biosciences Institute have developed some suggestions on how to improve the regulation of all invasive plant species, including new biofuels plants.
For the first time, the complete genomes of three populations of aye-ayes--a type of lemur--have been sequenced and analyzed.
The results of the genome-sequence analyses are published this week in the journal Proceedings of the National Academy of Sciences (PNAS).
The research was led by George Perry, an anthropologist and biologist at Penn State University; Webb Miller, a biologist and computer scientist and engineer at Penn State; and Edward Louis of the Henry Doorly Zoo and Aquarium in Omaha, Neb., and Director of the Madagascar Biodiversity Partnership.
Bringing scientists a step closer to new treatments for diabetes, researchers at the University of Pittsburgh School of Medicine and The Mount Sinai Medical Center have discovered a novel mechanism that regulates the replication of insulin-producing beta cells in the pancreas. The findings were recently published online ahead of print in Diabetes, a journal of the American Diabetes Association.
COLUMBIA, Mo. – Childhood and adolescent obesity rates in the United States have increased dramatically in the past three decades. Being obese puts individuals at greater risk for developing Type 2 diabetes, a disease in which individuals have too much sugar in their blood. Now, University of Missouri researchers found vitamin D supplements can help obese children and teens control their blood-sugar levels, which may help them stave off the disease.
COLUMBUS, Ohio – New research explains how certain traits can pass down from one generation to the next – at least in plants – without following the accepted rules of genetics.
Scientists have shown that an enzyme in corn responsible for reading information from DNA can prompt unexpected changes in gene activity – an example of epigenetics.
The welfare of poultry could be improved by a discovery about how chickens regulate their appetites.
Scientists have identified how a chicken's genetic make-up can affect the signals sent from its stomach to its brain that tell a chicken when it has had enough to eat.
Poultry farmers often have to restrict food for chickens because some birds are insensitive to feelings of fullness and can overeat, affecting their ability to reproduce.
The study could make it easier to develop methods to develop diets that reduce excess growth more naturally in these birds.
A new study looking at the potential health benefits of organic versus non-organic food found that fruit flies fed an organic diet recorded better health outcomes than flies fed a nonorganic diet.
The study from the lab of SMU biologist Johannes H. Bauer, Southern Methodist University, Dallas, found that fruit flies raised on diets of organic foods performed better on several tests for general health.
DETROIT – In a nationwide study of patients undergoing surgery for cancer, Henry Ford Hospital researchers have found that while infections during hospital stays increased during a 10-year period, the death rate from those infections dropped.
The findings suggest that diagnosis and management of healthcare-associated infection, or HAI, have improved over time.
The study appears in the current issue of the journal Cancer.
