TAMPA, Fla. (July 20, 2016) - University of South Florida researchers investigating the aftermath of a September, 2014 sewer line break in St. Petersburg, Florida, have found dangerous antibiotic-resistant bacteria in the untreated wastewater that gushed into neighborhoods and into Boca Ciega Bay at a rate of 250 to 500 gallons per minute.

SAN DIEGO: A safety team at a Canadian hospital determined there was too much traffic in and out of the operating room (OR) during total joint replacement procedures. So they implemented several strategies to reduce traffic, which may have contributed to a decrease in orthopedic surgical site infections (SSIs), according to study results presented today at the 2016 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP®) Conference.
NEW YORK, NY, July 18, 2016--Intranasal flu vaccines may be able to provide long-lasting protection against pandemic flu strains, according to a new study from immunologists at Columbia University Medical Center (CUMC).
The researchers found that, in mice, the intranasal flu vaccine FluMistTM (Medimmune) led to the production of T cells in the lungs that provided long-term protection against multiple flu strains, including those that were not present in the vaccines. Mice given the traditional injectable vaccine, such as FluzoneTM (Sanofi Pasteur), did not produce these cells.
(PHILADELPHIA) - Over 90 percent of prostate cancers are detected at a curable stage, with men more likely to die of other diseases than from this cancer. Although patients with localized, low-risk prostate cancer have treatment options: active surveillance, also called watchful waiting, in which the cancer is monitored periodically to detect any changes, or active treatment with surgery and radiation. This choice is challenging, because medical science cannot reliably identify those men who are at risk for developing aggressive disease and may benefit from active treatment.
BIRMINGHAM, Ala. - A recent study conducted by researchers at the University of Alabama at Birmingham and Johns Hopkins University School of Medicine published in PLOS ONE shows that symptoms of chronic fatigue syndrome, a complex and disabling multisystem disorder, can be provoked by imposing a mild to moderate strain to the muscles and nerves.
It is common knowledge that the modern turtle shell is largely used for protection. No other living vertebrate has so drastically altered its body to form such an impenetrable protective structure as the turtle.
However a new study by an international group of scientists, including those from the Evolutionary Science Institute at Wits University, on the earliest partially shelled fossil turtles suggests the broad ribbed proto shell was initially an adaptation, not for protection, but rather for burrowing underground.
OAK BROOK, Ill. - Radiologists who graduated from medical school after 1940 do not face an increased risk of dying from radiation-related causes like cancer, according to a new study appearing online in the journal Radiology. Researchers said the findings point to the success of efforts to reduce occupational radiation doses over the past several decades.
- Highest increase among men ages 55 to 69, who could benefit the most from screening and early treatment
- Disease is more advanced when finally diagnosed
- "Screening saves lives," urologists stress. "If I were a patient, I would want to be vigilant."
Chimpanzees travelling far and for longer time periods use tools more frequently to obtain food. This conclusion results from an analysis of seven years of field experiments conducted at the Department of Comparative Cognition at the University of Neuchâtel and the Swiss Centre for Affective Sciences at the University of Geneva (UNIGE), Switzerland.
What happens when red blood cells become damaged or reach the end of their normal life span, and how is the iron required for carrying oxygen recycled? A new study led by Massachusetts General Hospital (MGH) investigators contradicts previous thinking about where and how worn-out red blood cells are disposed of and their iron retained for use in new cells. Their findings, being published online in Nature Medicine, may lead to improved treatment or prevention of anemia or iron toxicity.
A new study published online by JAMA Pediatrics suggests bariatric surgery was associated with faster walking by teens, less walking-related musculoskeletal pain and lower heart rates as soon as six months following surgery and as long as two years after surgery.
Like adults, teens are not immune to the consequences of severe obesity, which can exacerbate functional mobility limitations and lead to a decline in physical activity because of the resulting musculoskeletal pain.
African American men living below poverty had the lowest overall survival in a study that examined the effects of sex, race and socioeconomic status on overall mortality, according to an article published online by JAMA Internal Medicine.
Investigators from the National Institutes of Health have discovered that cells from HIV-infected people whose virus is suppressed with treatment harbor defective HIV DNA that can nevertheless be transcribed into a template for producing HIV-related proteins. This finding may affect scientists' understanding of the long-term effects of HIV infection and what a cure would require.
Biochemists at the University of California San Diego have developed artificial cell membranes that grow and remodel themselves in a manner similar to that of living mammalian cells.
A research team including a Scripps Institution of Oceanography at the University of California San Diego climate scientist simulated in a computer model, for the first time, the realistic evolution of global mean surface temperature since 1900.
In doing so, the researchers also created a new method by which researchers can measure and monitor the pace of anthropogenic global warming, finding that the contribution of human activities to warming in the surface waters of the Pacific Ocean can be distinguished from natural variability.
