Communication makes hunting easier for chimpanzees
Similar to humans, chimpanzees use communication to coordinate their cooperative behavior — such as during hunting. When chimpanzees produce a specific vocalization, known as the “hunting bark,” they recruit more group members to the hunt and capture their prey more effectively, researchers at the University of Zurich and Tufts University have now shown. Chimpanzees don’t […]
Younger Kids ‘Should’ Get COVID Booster, Says CDC Panel
Similar to their older peers, children ages 5 to 11 should get a third dose of Pfizer/BioNTech’s COVID-19 vaccine (Comirnaty), the CDC’s Advisory Committee on Immunization Practices (ACIP) said on Thursday. In an 11-1 vote, with one abstention, the committee agreed that children ages 5 to 11 should receive an additional dose of the mRNA […]
Can Trained Dogs Sniff Out COVID-Positive Travelers?
Four trained dogs detected people who were positive for SARS-CoV-2 with similar accuracy to PCR tests, according to a randomized trial and real-life study at a busy international airport earlier in the pandemic. In the validation trial, the dogs had 92% accuracy, with 92% sensitivity (95% CI 89-94) and 91% specificity (95% CI 89-93) compared […]
Fungi-based meat alternatives to help save Earth’s forests
The market-ready meat alternative is very similar in taste and texture, but is a biotech product which — by replacing beef — involves much less land resources and greenhouse gas emissions from agriculture and land-use change. This goes under the assumption of a growing world population’s increasing appetite for beefy bites, and it is the […]
Study finds children with vegetarian diet have similar growth and nutrition compared to children who eat meat: Children with a vegetarian diet also had higher odds of underweight weight status
A study of nearly 9,000 children found those who eat a vegetarian diet had similar measures of growth and nutrition compared to children who eat meat. The study, published in Pediatrics and led by researchers at St. Michael’s Hospital of Unity Health Toronto, also found that children with a vegetarian diet had higher odds of […]
Can You Be Bipolar and Schizophrenic?
Are schizophrenia and bipolar disorder the same? Schizophrenia and bipolar disorder have similar symptoms, which can make them hard to diagnose. Sometimes people have both disorders, or they have a mix of symptoms from both conditions at the same time or close together, which is called schizoaffective disorder. Schizophrenia and bipolar disorder have similar symptoms, […]
‘Knocked All Our Assumptions for a Loop’: What We Heard This Week
“We’d all like it to be true. There were similar conjectures before the Delta variant appeared and knocked all our assumptions for a loop.” — Stephen Morse, PhD, of Columbia University Medical Center, on predictions that we’re all but done with the pandemic of the century. “To see a movie in the theater was quite […]
Can Lighter-Weight Mesh Cut Pain in Open Ventral Hernia Repair?
While offering similar clinical benefits at 1 year, a medium-weight polypropylene mesh was no better for pain control than a heavy-weight mesh in patients who underwent open retromuscular ventral hernia repair, a randomized multicenter trial showed. In fact, for the more than 300 patients in the trial, the two meshes resulted in identical pain scores […]
ADT Options for Prostate Cancer Come Out Even for Heart Safety
Androgen deprivation therapy (ADT) options for prostate cancer seemed to have a similar impact on the risk of cardiovascular events among people with documented heart disease, according to results from the PRONOUNCE trial, although the study was terminated early due to slow accrual. In 545 men, there was no statistically significant difference in the rate […]
Seabed recovers more quickly following extreme storms than from the impacts of bottom-towed fishing
Extreme storms can result in major damage to the seabed similar to that caused by prolonged periods of bottom-towed fishing, according to new research. However, important seabed habitats and species recover more quickly following extreme storms than in the wake of such fishing activity. That is one of the key findings of a first-of-its-kind study […]
