Hydrothermal vents on the bottom of the ocean host a broad range of rare and unusual ecosystems. They can be spread very far apart, and yet there will often be overlap in the creatures which inhabit them. Researchers, including those from the University of Tokyo, answer a long-standing question in this field about how creatures migrate between hydrothermal vents. Their process involves inspecting the chemical nature of limpet shells to reconstruct their likely journeys, yielding some surprising results. 

Honeybees given prebiotics and probiotics may survive better under temperature-related stress, suggesting that such nutritional supplements might enhance colony resilience

A collection of fossilized dinosaur bones from Wyoming feature tooth marks that provide evidence that some bites were likely created by Tyrannosaurus rex, according to a study published July 15, 2026 in the open access journal PLOS One by Bethania C. T. Siviero from Loma Linda University, USA, and colleagues.

Scientists have described a new species of colobus monkey in the forests of the Democratic Republic of Congo (DRC), report John Hart at Lukuru Wildlife Research Foundation and colleagues on July, 2026 in the open access journal PLOS One.

A team of researchers has confirmed the discovery of a previously unknown species of African monkey in the rainforests of the Democratic Republic of Congo (DRC), marking one of the most significant primate discoveries in decades.

In the rainforests of the Democratic Republic of Congo, scientists have uncovered a previously unknown species of monkey named Colobus congoensis. The discovery marks only the fifth new monkey species in Africa identified in the past 75 years. Genetic and anatomical analyses confirmed it as a distinct species, separated from its closest relative by 4 to 5 million years of evolution. Found only within a small range of roughly 1,700 square kilometers, the monkey, which is mainly black with striking orange face patches confronts growing pressure from habitat loss and hunting and is being recommended for endangered conservation status.

Horses know a predator when they see one – even if it’s only on a video screen they’re watching in a stall, with no sounds, smells or previous experience providing context to what they’re viewing, a new study suggests. And though sensors indicated the horses’ heart rates increased when they were looking at wolves on the screen, they otherwise kept a poker face. They didn’t bob their heads or swish their tails, and their gaze wasn’t fixed in a way that would indicate their brain was processing a threat, results showed. The findings are relevant to horse and human welfare: Riders and handlers may not be able to tell when a horse is agitated.

 

Scientists have discovered marsupial forelimbs (arms) develop before birth much earlier than previously thought, providing new insights into evolutionary innovation and biology.
