Walleye, an iconic native fish species in Wisconsin, the upper Midwest and Canada, are in decline in northern Wisconsin lakes, according to a study published this week in the Canadian Journal of Fisheries and Aquatic Sciences.

It may be time to tailor students' class schedules to their natural biological rhythms, according to a new study from UC Berkeley and Northeastern Illinois University.

Researchers tracked the personal daily online activity profiles of nearly 15,000 college students as they logged into campus servers.

After sorting the students into "night owls," "daytime finches" and "morning larks" -- based on their activities on days they were not in class -- researchers compared their class times to their academic outcomes.

One in 10 electronic dance music (EDM) party attendees have misused opioids in the past year, exceeding the national average, finds a study by the Center for Drug Use and HIV/HCV Research (CDUHR) at NYU Meyers College of Nursing.

The study, published in the journal Drug and Alcohol Dependence, suggests that prevention and harm reduction efforts need to target this increasingly popular scene as efforts continue toward reducing the opioid crisis.

ATLANTA--Child sexual abuse in the United States is costly, with an average lifetime cost of $1.1 million per death of female victims and $1.5 million per death of male victims, according to a new study.

Researchers measured the economic costs of child sexual abuse by calculating health care costs, productivity losses, child welfare costs, violence/crime costs, special education costs and suicide death costs.

Irvine, Calif., March 29, 2018 - Materials inspired by disappearing Hollywood dinosaurs and real-life shy squid have been invented by UCI engineers, according to new findings in Science this Friday.

The thin swatches can quickly change how they reflect heat, smoothing or wrinkling their surfaces in under a second after being stretched or electrically triggered. That makes them invisible to infrared night vision tools or lets them modulate their temperatures.

Despite tough banking rules put in place after last decade's housing crash, the mortgage market again faces the risk of a meltdown that could endanger the U.S. economy, warn two Berkeley Haas professors in a paper co-authored by Federal Reserve economists. The threat reflects a boom in nonbank mortgage companies, a category of independent lenders that are more lightly regulated and more financially fragile than banks--and which now originate half of all US home mortgages.

One of the many downsides of too much carbon dioxide in the atmosphere is what happens when some of that CO2 is absorbed by the oceans. As atmospheric CO2 levels increase from burning fossil fuels, this carbon dioxide is soaked up by seawater and makes the oceans more acidic.

Increased acidity is bad news for coral reefs and creatures whose shells are made from calcium carbonate, but how does it affect the entire food web?

PITTSBURGH--Carnegie Mellon University computer scientists have developed a system that can translate a wide variety of 3-D shapes into stitch-by-stitch instructions that enable a computer-controlled knitting machine to automatically produce those shapes.

Researchers are getting closer to understanding the molecular processes that cause parts of cell membranes to morph into tiny tubes that can transport molecules in and out of cells.

NEW YORK, NY (March 28, 2018) - New data from the American Society for Aesthetic Plastic Surgery (ASAPS) shows that many modern cosmetic surgical procedures are on the rise, and that surgical procedures account for 77% of all surveyed physicians' business. The latest annual survey (Cosmetic Surgery National Data Bank Statistics) from the organization now reflects input exclusively from ABPS board-certified plastic surgeons, which previously encompassed data from physicians in a wider range of specialties.

WASHINGTON, DC (March 28, 2018)--Dining out more at restaurants, cafeterias and fast-food outlets may boost total levels of potentially health-harming chemicals called phthalates in the body, according to a study out today. Phthalates, a group of chemicals used in food packaging and processing materials, are known to disrupt hormones in humans and are linked to a long list of health problems.

Scientists have identified potential biomarkers in nonhuman primates exposed to Ebola virus (EBOV) that appeared up to four days before the onset of fever, according to research published today in the journal Science Translational Medicine.

HANOVER, N.H. - March 28, 2018 - The West Greenland Ice Sheet melted at a dramatically higher rate over the last twenty years than at any other time in the modern record, according to a study led by Dartmouth College. The research, appearing in the journal Geophysical Research Letters, shows that melting in west Greenland since the early 1990s is at the highest levels in at least 450 years.

The slow fade of radioactive elements following a supernova allows astrophysicists to study them at length. But the universe is packed full of flash-in-the pan transient events lasting only a brief time, so quick and hard to study they remain a mystery.

Only by increasing the rate at which telescopes monitor the sky has it been possible to catch more Fast-Evolving Luminous Transients (FELTs) and begin to understand them.

Maunakea, Hawaii - Galaxies and dark matter go hand in hand; you typically don't find one without the other. So when researchers uncovered a galaxy, known as NGC1052-DF2, that is almost completely devoid of the stuff, they were shocked.
