City College of New York biologist Shubha Govind and her research team have identified the composition of "virus-like particles" (VLPs) found in the venom of a wasp that is a parasite of fruit flies. Invisible to the eye, wasp VLPs suppress the flies' immune responses by killing their blood cells.

WASHINGTON, Sept. 15, 2017 -- The Cassini-Huygens mission to Saturn, a collaboration between NASA and the European Space Agency, is set to end on Sept. 15. The mission has told us a great deal about the unique and unexpected chemistry of Saturn's moon Titan, and it has changed the way we think about our own planet and the entire solar system.

Fall-planted cover crops are often used as part of an integrated weed control program in herbicide-resistant soybean crops. But researchers writing in the journal Weed Technology say not all cover crops are equally effective against Palmer amaranth, waterhemp and other Amaranthus spp. weeds.

Their conclusions follow a two-year, multistate study to compare the impact of cereal rye, spring oat, forage radish and annual ryegrass on weed control and crop yields. The study was conducted in areas with known infestations of Amaranthus spp. weeds.

CHICAGO (Sept/ 15, 2017) - Patients and families who use telemedicine for sports medicine appointments saved an average of $50 in travel costs and 51 minutes in waiting and visit time, according to a new study by Nemours Children's Health System. Each telemedicine visit also saved the health system an average of $24 per patient, researchers reported at the American Academy of Pediatrics National Conference & Exhibition.

CHICAGO - Research being presented at the American Academy of Pediatrics 2017 National Conference and Exhibition shows that post-surgical opioid pain medications prescribed after common surgeries may become a pathway to continued, nonmedical opioid use by teens and young adults.

The study abstract, "Persistent Opioid Usage among Pediatric Patients Following Surgery in the United States," will be presented on Sunday, Sept. 17, at the Marriott Marquis Chicago.

SEATTLE - Countries have saved more lives over the past decade, especially among children under age 5, but persistent health problems, such as obesity, conflict, and mental illness, comprise a "triad of troubles," and prevent people from living long, healthy lives, according to a new scientific study.

When tennis great John McEnroe recently claimed that women's champion Serena Williams wouldn't even be a "top 700" men's player, his controversial comment made headlines on sports shows and beyond.

It was just one more example of how hard it continues to be for women's sports to receive any attention at all, unless it is somehow filtered through a very dismissive male gaze.

The notorious genetic marker of Alzheimer's disease and other forms of dementia, ApoE4, may not be a lone wolf.

Researchers from USC and the University of Manchester have found that another gene, TOMM40, complicates the picture. Although ApoE4 plays a greater role in some types of aging-related memory ability, TOMM40 may pose an even greater risk for other types.

In a recent study, screening rates for hepatitis C virus (HCV) infection among baby boomers increased fivefold in the year following implementation of an electronic health record (EHR)-based prompt for primary care physicians. The prompt also led to dramatic increases in follow-up specialized care for infected patients, according to the Hepatology study.

An international team of researchers reports that when children are praised for being smart not only are they quicker to give up in the face of obstacles they are also more likely to be dishonest and cheat. Kids as young as age 3 appear to behave differently when told "You are so smart" vs "You did very well this time."
