San Antonio, Texas, June 4, 2012 – Prisoners need education on the appropriate use of topical antibiotic products, according to a study released today at the 39th Annual Educational Conference and International Meeting of the Association for Professionals in Infection Control and Epidemiology (APIC).

San Antonio, Texas, June 4, 2012 – Preventing further complications in patients who develop infections after surgery to replace a knee or hip could save the U.S. healthcare system as much as $65 million annually, according to an analysis presented today at the 39th Annual Educational Conference and International Meeting of the Association for Professionals in Infection Control and Epidemiology (APIC).

Consumer products known as "bug bombs" or "foggers" have been sold for decades for use against many common household insects. However, recent research published in the Journal of Economic Entomology (JEE) shows these products to be ineffective against bed bugs.

Researchers at the University of California, Davis, report that ancient farmers had a stronger impact on the evolution of maize, or corn, than modern plant breeders have had on the grain — now one of the world's top production crops.

An interdisciplinary team, led by researchers at Cornell University and the U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS), today published the most comprehensive analysis to date of the corn genome.

The team expects the achievement to speed up development of improved varieties of one of the world's most important agricultural commodities. The results should boost international efforts to increase yields, expand areas where corn can be cultivated and produce varieties better equipped to resist pests and disease.

June 3, 2012, Shenzhen, China – BGI, the world's largest genomics organization, together with other 17 international institutes, announced that they completed the second generation of maize HapMap (Maize HapMap2) and genomics studies on maize domestication and improvement. The two separate studies were published online in the same issue of Nature Genetics.

LA JOLLA, CA – A new study led by scientists at The Scripps Research Institute suggests that the replication process for DNA—the genetic instructions for living organisms that is composed of four bases (C, G, A and T)—is more open to unnatural letters than had previously been thought. An expanded "DNA alphabet" could carry more information than natural DNA, potentially coding for a much wider range of molecules and enabling a variety of powerful applications, from precise molecular probes and nanomachines to useful new life forms.

Many men with metastatic, hormone-sensitive prostate cancer live longer on continuous androgen-deprivation therapy (also known as hormone therapy) than on intermittent therapy, according to a seventeen-year study led by SWOG, a cancer research cooperative group funded by the National Cancer Institute (NCI).

CHICAGO, IL – Researchers and doctors at the North Shore-LIJ Health System and the Feinstein Institute for Medical Research have discovered a potential explanation for why breast cancer is not experienced the same way with African American and Caucasian patients. This data will be presented at the 2012 American Society of Clinical Oncology (ASCO) Annual Meeting to be held from Friday through Tuesday (June 1-5) in Chicago, IL.

A new medication proved effective in slowing the spread of metastatic prostate cancer, while helping to maintain the quality of life, in patients with advanced disease. The phase 3 study was unblinded midway, allowing patients receiving the placebo to instead take the drug because of the favorable results.

Computer-designed proteins are under construction to fight the flu. Researchers are demonstrating that proteins found in nature, but that do not normally bind the flu, can be engineered to act as broad-spectrum antiviral agents against a variety of flu virus strains, including H1N1 pandemic influenza.

"One of these engineered proteins has a flu-fighting potency that rivals that of several human monoclonal antibodies," said Dr. David Baker, professor of biochemistry at the University of Washington, in a report in Nature Biotechnology.

The glacier lily as it's called, is a tall, willowy plant that graces mountain meadows throughout western North America. It flowers early in spring, when the first bumblebees and hummingbirds appear.

Or did.

The lily, a plant that grows best on subalpine slopes, is fast becoming a hothouse flower. In Earth's warming temperatures, its first blooms appear some 17 days earlier than they did in the 1970s, scientists David Inouye and Amy McKinney of the University of Maryland and colleagues have found.

CHICAGO, IL (June 1, 2012)––Inflammatory breast cancer is a very aggressive type of cancer associated with early metastasis and poor survival rates, and the prognosis is even worse for patients with tumors expressing the ErbB2 receptor. The ErbB2-inhibiting drug lapatinib can slow the spread of cancer cells in individuals with advanced breast cancer who have already tried other chemotherapy medications.

CHICAGO, IL (June 1, 2012)––More than one-fifth of people who have received referrals to test for cancer-causing genes say they will only undergo testing if their insurance covers the cost—just as more insurers are instituting cost-sharing for medical services like genetic testing, according to new findings from Fox Chase Cancer Center in Philadelphia released at this year's 2012 Annual Meeting of the American Society of Clinical Oncology on Saturday, June 2.

CHICAGO, IL (June 1, 2012)––A new compound that targets anaplastic lymphoma kinase-positive (ALK+) non-small cell lung cancer is well-tolerated by patients and is already showing early signs of activity, including in patients who no longer respond to crizotinib—the only approved ALK inhibitor. Results of this Novartis-sponsored sudy will be presented by a researcher from Fox Chase Cancer Center during the 2012 Annual Meeting of the American Society of Clinical Oncology on Sunday, June 3.
