Inside cells, two important enzymes act like small central regulatory hubs: dipeptidyl peptidase 8 and 9—DPP8/9 for short. Among other things, they regulate inflammatory reactions and influence whether a cell survives or dies. These mechanisms are especia

There are two species of streamertail hummingbirds on the island of Jamaica, West Indies—one with red-billed males (Trochilus polytmus) and the other with black-billed males (T. scitulus). This is a puzzling situation, as many evolutionary biologists have

Ubiquinone, a metabolite critical to generating energy in cells, has long been thought to be the only mitochondrial electron transport chain carrier in mammals. Although other electron transporters have been identified in bacteria, nematodes and other org

A new study conducted by animal behavior and mammalian cognition experts at the Universities of Lincoln and Sussex, and Jean Monnet University, reveals that dogs may be far better at understanding human speech than previously understood.

A new study from Umeå University has revealed that trees' circadian clocks guide their growth and the timing of seasonal events like the appearance of leaves in spring. The researchers investigated the growth of genetically modified poplars in greenhouse

Researchers at Pitt have produced the most detailed image to date of a bacteriophage–phage for short–that has allowed them to see for the first time the structural makeup of the part of the phage that directly attaches to its target Mycobacterium cell.

A new brain imaging study from the ELTE NAP Canine Brain Research group has revealed that age and brain shape affect how strongly dogs' olfactory brain regions are connected. The researchers used resting-state fMRI on awake dogs to map olfactory function

New research has uncovered how a simple circadian clock network demonstrates advanced noise-filtering capabilities, enhancing our understanding of how biological circuits maintain accuracy in dynamic natural environments.

A study of bumble bees has uncovered a potential reason for the insects' decline. By studying bumble bee exposure to particulate air pollutants, scientists at the University of Leicester have determined that the diversity and behavior of the bee gut micr

The development and spread of antibiotic resistance represents one of the greatest threats to global health. To overcome these resistances, drugs with novel modes of action are urgently needed.

A spat between birds at a backyard birdfeeder highlights the sometimes fierce competition for resources that animals face in the natural world, but some ecologically similar species appear to coexist peacefully. A classic study in songbirds by Robert MacA

Scientists have unveiled a new food source designed to sustain honey bee colonies indefinitely without natural pollen.
