Climate Change Alters a Human-Raptor Relationship
Cornell University

Bald Eagles and dairy farmers exist in a mutually beneficial relationship in parts of northwestern Washington State. According to a new study, this "win-win" relationship has been a more recent development, driven by the impact of climate change on eagles' traditional winter diet of salmon carcasses, as well as by increased eagle abundance following decades of conservation efforts.

Penn Medicine Research Suggests More Cancers Can Be Treated with Drugs Than Previously Believed
Perelman School of Medicine at the University of Pennsylvania

Up to 50 percent of cancer-signaling proteins once believed to be immune to drug treatments due to a lack of targetable protein regions may actually be treatable, according to a new study from the Perelman School of Medicine at the University of Pennsylvania. The findings, published this month in Nature Communications, suggest there may be new opportunities to treat cancer with new or existing drugs.

Not getting enough sleep could blunt antibody response to vaccination, leaving you more vulnerable to infection
University of Chicago Medical Center

In reviewing data from previous studies, a team lead by researchers at the University of Chicago and the French National Institute of Health and Medical Research (Inserm) found that individuals who had fewer than six hours of sleep per night in the days surrounding vaccination had a blunted antibody response. That indicates efforts to promote heathy sleep duration ahead of an immunization could be an easy way to improve vaccine effectiveness.

Northern and southern resident orcas hunt differently, which may help explain the decline of southern orcas
University of Washington

In the Pacific Northwest and British Columbia, southern resident orcas have experienced no net population growth since the 1970s. But northern resident orcas, with a similar diet and territory, have grown steadily. A new study may help explain why: The two populations differ in how they hunt for salmon, their primary and preferred food source.

UT Southwestern scientists discover agent that reverses effects of intoxication
UT Southwestern Medical Center

A shot of a liver-produced hormone called FGF21 sobered up mice that had passed out from alcohol, allowing them to regain consciousness and coordination much faster than those that didn’t receive this treatment, UT Southwestern researchers report in a new study. The findings, published in Cell Metabolism, could lead to effective treatments for acute alcohol intoxication, which is responsible for about 1 million emergency room visits in the U.S. each year.

Eye experts weigh in on artificial tears in midst of infectious outbreak
NIH, National Eye Institute (NEI)

Questions remain about artificial tears linked to an outbreak of Pseudomonas aeruginosa infections involving 64 people in 13 states, including 8 cases of vision loss, as well as lung and urinary tract infections, and one death. Federal agencies warned people to stop using EzriCare and Delsam Pharma artificial tears after tests of opened bottles used by those affected found a rare, extensively drug-resistant strain of P. aeruginosa. The strain had never been reported in the United States.What is clear is that eye health experts have advice for people using artificial tears, which are sold over the counter and widely used for eye irritation associated with dry eye disease, contact lens use, and refractive surgery, as well among those using other eye drops regularly, such as for glaucoma.

Pregnant Shark birth tracking technology provides key data for species protection
Arizona State University (ASU)

In a new study, researchers used new technologies to remotely document, for the first time in the wild, the location and timing of shark birth. Named the Birth-Alert-Tag (BAT), this new satellite tag remained inside the uterus, along with the developing shark pups, until the mother shark gave birth and expelled the newborn pups, along with the BAT, into the surrounding water. The BAT then floated to the surface and transmitted to satellites the location of where the shark birth took place. The first of its kind, the BATs were successfully deployed in a tiger shark and scalloped hammerhead shark, documenting the location birth.

CBD May Increase the Adverse Effects of THC in Edible Cannabis Products, Study Shows
Johns Hopkins Medicine

Contrary to some common claims, a study led by Johns Hopkins Medicine researchers found that relatively high doses of cannabidiol (CBD) may increase the adverse effects of delta-9-tetrahydrocannabinol (THC), the main active ingredient in cannabis that can cause a mood alteration or a “high” sensation. The findings show that in edible cannabis products, CBD inhibits the metabolism, or breakdown, of THC, which may result in stronger and longer drug effects.
