New study overturns popular theory on evolution of termite size
Researchers have completed a comprehensive analysis of the head width of over 1500 species of termites and determined that their size isn’t gradually shrinking at a geological timescale. Termites belong to the cockroach branch of the evolutionary tree. They split from their sister cockroach group at the end of the Jurassic period, around 150 to […]
Plasma-based engineering creates contact-killing, antifouling, drug-release surfaces: Technology could accelerate antimicrobial material development
The deepening concern over antibiotic-resistant infections, coupled with prevailing hospital-acquired infections from surgical tools, implants, and heavily touched surfaces, has ramped up antimicrobial material development in recent years. Conventional wet-chemistry methods used to create biocidal materials are complex, time-consuming, and expensive. In the Journal of Applied Physics, by AIP Publishing, researchers from Belgium, Czech Republic, […]
What Is a Pandemic? Stages & Protective Measures
Pandemic is a term used to describe the spread of an infectious disease over a large geographic area that affects a large number of people Pandemic is a term used to describe the spread of an infectious disease over a large geographic area that affects a large number of people. Due to the high morbidity […]
Chemical pollutants disrupt reproduction in anemonefish
Ocean pollution is unfortunately becoming more commonplace, raising concerns over the effect of chemicals that are leaching into the water. In a new study, researchers have discovered how these chemicals can affect the reproduction in common anemonefish Amphiprion ocellaris. Endocrine disrupting chemicals — which interfere with how the body’s hormones work — can obstruct normal […]
Cannabis Use Climbing in Pregnancy Among People With HIV
Among pregnant people living with HIV, marijuana use climbed over the last decade both in pregnancy and during the postpartum period, according to results from a cohort study. Prevalence of marijuana use during pregnancy among people living with HIV increased from 7.1% in 2007 to 11.7% in 2019, reported Lynn Yee, MD, MPH, of Northwestern […]
Black, Hispanic Men Left Behind on Declining HIV Rates in the U.S.
While the number of new HIV infections fell among white men who have sex with men (MSM) over the past decade, infection rates among Black and Hispanic/Latino MSM were less positive, according to the CDC. In a new Vital Signs report, researchers highlighted racial disparities in HIV trends from 2010 to 2019, with new infections […]
Engineers design autonomous robot that can open doors, find wall outlet to recharge
One flaw in the notion that robots will take over the world is that the world is full of doors. And doors are kryptonite to robots, said Ou Ma, an aerospace engineering professor at the University of Cincinnati. “Robots can do many things, but if you want one to open a door by itself and […]
New study proposes expansion of the universe directly impacts black hole growth
Over the past 6 years, gravitational wave observatories have been detecting black hole mergers, verifying a major prediction of Albert Einstein’s theory of gravity. But there is a problem — many of these black holes are unexpectedly large. Now, a team of researchers from the University of Hawai?i at M?noa, the University of Chicago, and […]
The ‘Healthy’ Pandemic Habit Secretly Messing With Your Mental Health
Spending more time at home ― as we’ve all been doing for over a year and a half ― has certainly had some perks. More time with family, less time commuting and more time wearing pants with an elastic waistband. One shift not on this list? The number of body image issues that have materialized […]
