At Least 70 Rogue Planets Uncovered in Our Milky Way

This artist’s impression shows an example of a rogue planet with the Rho Ophiuchi cloud complex visible in the background. Rogue planets have masses comparable to those of the planets in our Solar System but do not orbit a star, instead roaming freely on their own. Credit: ESO/M.

Wear and Tear in Vulnerable Brain Areas Lead to Lesions Linked to Cognitive Decline in Aging

Wear and Tear in Vulnerable Brain Areas Lead to Lesions Linked to Cognitive Decline in Aging

Lesions (red) occur near areas that must stretch more to accommodate pressure changes of the circulating cerebrospinal fluid. When the walls of the CSF-filled ventricle (black) wear thin, CSF leaks into the brain tissue (grey) and creates lesions. Credit: Stevens Institute of Technology Researchers at Stevens Institute of Technology show that strain on ventricular walls … Read more

People With Inflammatory Bowel Disease (IBD) Have More Microplastics in Their Feces

IBD Microplastics Feces

Higher numbers of microplastics of various shapes, such as sheets (left) and fibers (right) were found in the feces of people with IBD than in healthy controls. Credit: Adapted from Environmental Science & Technology 2021, DOI: 10.1021/acs.est.1c03924 Microplastics — tiny pieces of plastic less than 5 mm in length – are everywhere, from bottled water … Read more

Mistletoe – Famous for Christmastime Kisses – Is Actually a Parasitic Plant With Poisonous Berries

Mistletoe Kisses

Hanging mistletoe is a Christmas tradition. A parasitic plant with potentially poisonous berries might not sound like something that would boost your Christmas decorations to the next level. But, botanically speaking, that’s what mistletoe is. There are some 1,300 species of this evergreen plant worldwide. They’re all parasitic or semiparasitic, meaning they can survive only … Read more
