Pipelines carrying crude oil to ports in British Columbia may spell bad news for salmon, according to a new University of Guelph-led study.

Exposure to an oil sands product - diluted bitumen - impairs the swimming ability and changes the heart structures of young salmon.

The research will be published in the journal Environmental Toxicology and Chemistry, and is available online now.

It's a timely finding, says U of G post-doctoral researcher and lead author Sarah Alderman.

Many uncultured microbes play unknown roles in regulating Earth's biogeochemical processes; everything from regulating plant health to driving nutrient cycles in both terrestrial and marine environments, processes that can impact global climate. While researchers are harnessing multiple approaches to identify these microbes, referred to as "microbial dark matter," and determine what they're doing, most techniques don't allow them to do both at once.

Want to stop HIV infections? Get the immune system to recognize and attack the virus's tell-tale structure.

That's part of the basic approach behind efforts at The Scripps Research Institute (TSRI) to design an AIDS vaccine. This strategy may hinge on finding new ways to stabilize proteins called HIV-1 surface antigens and in designing HIV-like particles to prompt the body to fight the real virus.

Researchers at North Carolina State University have discovered that therapeutic stem cells exit the bloodstream in a different manner than was previously thought. This process, dubbed angiopellosis by the researchers, has implications for improving our understanding of not only intravenous stem cell therapies, but also metastatic cancers.

TALLAHASSEE, Fla. -- As thousands of young adults prepare to leave the nest and attend college for the first time, parents may want to examine whether they are kind and supportive or hovering into helicopter parent territory.

Parental involvement is crucial to a child's development into an adult, but Florida State University researchers are finding that crossing the line between supportive and too involved could indirectly lead to issues such as depression and anxiety for young adults.

Fewer female white-tailed deer disperse than males, but when they do, they typically travel more than twice as far, taking much more convoluted paths and covering larger areas, according to researchers in Penn State's College of Agricultural Sciences.

These findings, from a study in which 277 juvenile female deer were fitted with radio collars, has important deer-management implications in states where chronic wasting disease is known to be infecting wild, free-ranging deer, noted researcher Duane Diefenbach, adjunct professor of wildlife ecology.

When guessing the weight of an ox or estimating how many marbles fill a jar, the many have been shown to be smarter than the few. These collective displays of intelligence have been dubbed "the wisdom of crowds," but exactly how many people make a crowd wise?

CLEVELAND, Ohio (Wednesday, June 29, 2016)--In an article publishing online today in Menopause, the journal of The North American Menopause Society (NAMS), Rosamar E.F. Rezende, MD, PhD, and colleagues in São Paulo present results of their study testing the efficacy of aerobic exercise in postmenopausal women with nonalcoholic fatty liver disease (NAFLD). NAFLD is considered a cardiovascular disease risk factor, independent of other risk factors, and is associated with insulin resistance, abdominal obesity, hypertension, dyslipidemia, and type 2 diabetes mellitus.

Bottom Line: Women with a history of severe cervical intraepithelial neoplasia, a precancerous condition of the cervix that arises from infection with the human papillomavirus (HPV), had a long-term increased risk of developing anal, vulvar, and vaginal cancer.

Journal in Which the Study was Published: Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

Climate has influenced the distribution patterns of Adélie penguins across Antarctica for millions of years.

The geologic record shows that as glaciers expanded and covered Adélie breeding habitats with ice, penguin colonies were abandoned. When the glaciers melted during warming periods, this warming positively affected the Adélie penguins, allowing them to return to their rocky breeding grounds.

But now, University of Delaware scientists and colleagues report that this beneficial warming may have reached its tipping point.

When you visit your general practitioner you can get your blood analyzed for cholesterol and triglycerides, to get an idea of your risk for cardiovascular disease. With additional information about BMI, smoking habits and blood pressure, this can be used to calculate your 10-year risk for cardiovascular disease. There are several risk prediction calculators available today.

"Interphase" refers to the period in the cell cycle in which chromosomes spend most of their time. During this phase, in between mitoses, chromosomes live "dissolved'' in the nucleus where they carry out the processes required for the duplication of genetic material.

June 27, 2016 - LGBT rights and protections are scarce in constitutions around the world, UCLA study findsFSPH WORLD's study provides global analysis of constitutional rights based on sexual orientation and gender identity

Only five countries in the world have constitutions that explicitly guarantee equality for citizens on the basis of sexual orientation and gender identity.

In a sample study, researchers at Johns Hopkins say they have found an association between the makeup of an individual's microbiome and head and neck cancer, a finding that potentially advances the quest for faster and more accurate cancer diagnosis and therapy.
