Most evolutionary biologists distinguish one species from another based on reproductivity: members of different species either won’t or can’t mate with one another, or, if they do, the resulting offspring are often sterile, unviable, or suffer some other sort of reduced fitness.

Using a specially designed camera, researchers at Lund University in Sweden have succeeded for the first time in recreating how birds see colours in their surroundings.

Populations of coastal cutthroat trout and coastal giant salamanders in the Pacific Northwest show the ability to rebound quickly from drought conditions, new research by Oregon State University suggests.

If we are ever to reduce the quantity of plastics being dumped into the environment, efficient recycling is essential.

The quest for climate scientists to be able to bridge the gap between shorter-term seasonal forecasts and long-term climate projections is ‘coming of age’, a study shows.

2018: a year of drought – climate change causes an increase in the number of freshwaters that run dry, at least temporarily. 

A two to three-fold increase in heatwave activity in the United Kingdom since the late 19th century has been identified in a new analysis of historical daily temperature data led by University of Warwick scientists.

The population of Antarctic krill, the favourite food of many whales, penguins, fish and seals, shifted southward during a recent period of warming in their key habitat, new research shows.

Big earthquakes appear to follow a brief episode of “shallow mantle creep” and “seismic swarms,” suggests new research at Oregon State University that offers an explanation for the foreshocks observed prior to large temblors.

New research has found that a novel Artificial Intelligence (AI) system can dramatically reduce the time needed to ensure that abnormal chest X-rays with critical findings will receive an expert radiologist opinion sooner, cutting the average delay from 11 days to less than 3 days.
