New findings on the function of mitofusin 2 in the cellular energy metabolism

6 days 8 hours ago
Mitofusin 2 is a key protein in the regulation of the physiology of mitochondria—cellular organelles that produce energy—involved in several neurodegenerative and cardiovascular diseases, as well as in cancer. Now, a study published in the journal EMBO Reports reveals that the regulation of the bioenergetic activity in the mitochondria requires mitofusin 2 to be found in the endoplasmic reticulum, a system built by a complex network of membranes in the cell cytoplasm

Man's new best friend: What cats can teach us about human genetics and precision medicine

6 days 9 hours ago
Although cats have lived alongside humans for millennia, it remains a dogs' world. This bias has historically bled into science as well. It's time for cats to get their day, argues veterinary medicine expert Leslie Lyons in a Forum published July 28 in the journal Trends in Genetics. Cats, she says, have the potential to be a valuable model organism for geneticists, as the feline genome is ordered similarly to humans.

A caffeine buzz helps bees learn to find specific flowers

There's nothing like a shot of espresso when you need to get some studying done—and now, it seems like bees learn better with a jolt of their favorite caffeine-laced nectar, too. In a paper published July 28 in the journal Current Biology, researchers have shown that feeding bumble bees caffeine helps them better remember the smell of a specific flower with nectar inside. While previous studies have shown that bees like caffeine and will more frequently visit caffeinated flowers to get it, this is the first study to show that consuming caffeine in their nest actually helps bees find certain flowers outside of the nest.

Why big fish thrive in protected oceans

Big fish are harder to find in areas sprawling with human activity, unless you're looking in no-take marine reserves, according to a new study led by marine scientists at The University of Western Australia.

For animal societies, cohesion comes at a cost

6 days 10 hours ago
From gaining valuable information to staying safe from predators, moving in a group can benefit animals—but at what cost? Researchers from the Max Planck Institute of Animal Behavior have provided rare insight into the physical price that animals pay for moving collectively. Using accelerometers—the equivalent of pedometers, or Fitbits—the team of scientists studied the detailed movement behavior and related energetic costs in a troop of 25 baboons. The study is the first to gain ultra-high resolution data on movement and energetics of a group of wild primates.

What you need to know about the invasive spotted lanternfly spreading across the eastern U.S.

6 days 11 hours ago
The spotted lanternfly was first detected in Pennsylvania in 2014 and has since spread to 26 counties in that state and at least six other eastern states. It's moving into southern New England, Ohio and Indiana. This approximately 1-inch-long species from Asia has attractive polka-dotted front wings but can infest and kill trees and plants. We recently caught up with Professor Frank Hale, an entomologist who is tracking this species.

Dams fuel malaria cases in Africa

While dams are critical to ensuring water and food security throughout Sub-Saharan Africa, small dams in particular pose a greater risk of malaria transmission, a study says.
