Discoveries about how the human brain contributes to our success – both as a species and as individuals – are among the first fruit of projects funded under the National Institutes of Health BRAIN Initiative program as well as the Human Connectome Project.
About 20 million years ago a single flea became entombed in amber with tiny bacteria attached to it, providing what researchers believe may be the oldest evidence on Earth of a dreaded and historic killer – an ancient strain of the bubonic plague.
Researchers from the University of Bristol describe how they used radiocarbon measured in deep-sea fossil corals to shed light on carbon dioxide (CO2) levels during the Earth’s last deglaciation.
For the first time, an international team of researchers has sequenced the complete genomes of eleven Przewalski’s horses, including all of the founding lineages and five historical, museum specimens dating back more than a century.
A first draft of the “tree of life” for the roughly 2.3 million named species of animals, plants, fungi and microbes has been released, and two University of Michigan biologists played a key role in its creation.
The African clawed frog is tongue-less, has long, curvy toes and eyes that are perched on top of its head, but that’s not all that’s odd about it.
Why do certain body shape and size relationships remain consistent over long periods? One such example is found in flies, where small wings are normally rounder than large wings.
In the last 30,000 years there was, at times, more mixing in the Southern Ocean than previously thought.
Snowpack in California’s Sierra Nevada in 2015 was at the lowest level in the past 500 years, according to a new report led by University of Arizona researchers.
The globe’s forests have shrunk by three per cent since 1990 – an area equivalent to the size of South Africa – despite significant improvements in conservation over the past decade.
In ongoing research to record the interaction of environment and evolution, a team led by University of California, Riverside biologist David Reznick has found new information illustrating the evolution of a population of guppies.
An international research team led by University of Otago scientists has documented prehistoric “sanctuary” regions where New Zealand seabirds survived early human hunting.
Ice Age paleontologist Prof. Dr. Ralf-Dietrich Kahlke of the Senckenberg Research Station for Quaternary Paleontology in Weimar recorded the maximum geographic distribution of the woolly mammoth during the last Ice Age and published the most accurate global map in this regard.
The second ice age during the Cryogenian period was not followed by the sudden and chaotic melting-back of the ice as previously thought, but ended with regular advances and retreats of the ice, according to research published by scientists from the University of Birmingham in the journal Nature Geoscience.
Humans are just one of many predators in this world, but a new study highlights how their intense tendency to target and kill adult prey, as well as other carnivores, sets them distinctly apart from other predators. As humans kill other species in their reproductive prime, there can be profound
Indiana University paleobotanist David Dilcher and colleagues in Europe have identified a 125 million- to 130 million-year-old freshwater plant as one of earliest flowering plants on Earth.
Early humans were the dominant cause of the extinction of a variety of species of giant beasts, new research has revealed.
Hawai’i has been called the “extinction capital of the world.” But, with the exception of the islands’ birds, there has until now been no accurate assessment of the true level of this catastrophic loss.
Documents dating back to the 16th Century provide a unique insight into one of Darwin’s landmark studies – according to new research from the University of East Anglia.
An intriguing study involving walking stick insects led by the University of Sheffield in England and the University of Colorado Boulder shows how natural selection, the engine of evolution, can also impede the formation of new species.
When life on Earth began nearly 4 billion years ago, long before humans, dinosaurs or even the earliest single-celled forms of life roamed, it may have started as a hiccup rather than a roar: small, simple molecular building blocks known as “monomers” coming together into longer “polymer” chains and falling apart in the warm pools of primordial ooze over and over again.
As grasses grew more common in Africa, most major mammal groups tried grazing on them at times during the past 4 million years, but some of the animals went extinct or switched back to browsing on trees and shrubs, according to a study led by the University of Utah.
