Wrinkle-faced male bats lower face masks to copulate — ScienceDaily

The first behavioral observations of wrinkle-faced bats in their natural habitat reveal that this elusive species uses the rarest form of bat courtship behavior, according to a study published November 11 in the open-access journal PLOS ONE by Bernal Rodríguez-Herrera of the Universidad de Costa Rica, and colleagues. Centurio senex is a wrinkle-faced bat found […]

On Thin Ice: Tiger Stripes on Enceladus

When NASA’s Cassini mission arrived at Saturn’s moon Enceladus, it found geysers of material spewing from the southern hemisphere. Four long, parallel scratches, dubbed tiger stripes, scarred Enceladus’s south pole, venting material from the moon’s interior into space. But the moon’s north pole remained surprisingly unblemished, a mystery that has continued to puzzle […]

Chemical clues in leaves can reveal ash tree resistance to deadly disease

IMAGE: Ash trees with ash die back. view more  Credit: University of Warwick Naturally occurring compounds in ash leaves could be linked to susceptibility or resistance of individual trees to the fungal disease ash dieback (ADB). Scientists at the University of Warwick and University of Exeter have identified a group of chemicals present in ash leaves […]

Rare squid with ‘elbow’ tentacles baffles scientists in spooky new footage

It looks like an alien — head dwarfed by enormous flapping fins, body blobbing through dark water, thin blue tentacles streaming behind it in a tangle of neon spaghetti. But despite its otherworldly appearance, the elusive cephalopod known simply as the Bigfin squid (Magnapinnidae) may be more common in Earth‘s deep oceans than scientists ever […]

Protecting the brain from infection may start with a gut reaction

Some immune defenses of the brain may have their roots in the gut. A new study in mice finds that immune cells are first trained in the gut to recognize and launch attacks on pathogens, and then migrate to the brain’s surface to protect it, researchers report online November 4 in Nature. These cells were […]

Dark matter from the depths of the universe — ScienceDaily

Cataclysmic astrophysical events such as black hole mergers could release energy in unexpected forms. Exotic low-mass fields (ELFs), for example, could propagate through space and cause feeble signals detectable with quantum sensor networks such as the atomic clocks of the GPS network or the magnetometers of the GNOME network. These are the results of theoretical […]

Modeling Gravity Waves with Machine Learning

Gravity waves ripple outward from disturbances in the atmosphere, much like the ripples formed from tossing a stone into a still pond. Researchers know that these waves play a critical role in global atmospheric circulation, moving momentum between different layers. But gravity waves are still not well understood. Their small spatial scale and […]

These rock-eating microbes could help us settle the Moon and Mars

In this microscopic image, Sphingomonas desiccabilis is growing on basalt. (UK Centre for Astrobiology/University of Edinburgh–Rosa Santomartino/) If humans ever want to take the unprecedented step of establishing a base on the Moon, Mars, or any other celestial destination, they may need to extract resources from local rocks to support themselves. According to a new […]
