Understanding resistance rates and cross-resistance can improve the potency of sequential antibiotic treatment protocols. Sequential treatment using antibiotics that are similar but swapped around frequently…
Leaves display a remarkable range of forms from flat sheets with simple outlines to the cup-shaped traps found in carnivorous plants. A general question in…
There are way more species of horseshoe bats than scientists thought. If you’ve never seen a horseshoe bat, you’re missing out. Their comically large ears…
Fossilized flies that lived 54 million years ago have revealed a surprising twist to the tale of how insects’ eyes evolved. These craneflies, unveiled in…
About 400 million years ago, vertebrates first began to crawl from the primordial seas onto land. Last week, thanks to a cutting-edge mathematical-analysis technique, a…
An international team of researchers have uncovered the remains of a new species of human in the Philippines, proving the region played a key role…
When it comes to regeneration, some animals are capable of amazing feats. If you cut off a salamander’s leg, it will grow back. When threatened,…
Scientists have reproduced in the lab how the ingredients for life could have formed deep in the ocean 4 billion years ago. The results of…
The human brain owes its characteristic wrinkled appearance to its outer layer, the cerebral cortex. During human evolution, the neocortex, the evolutionarily youngest part of…
A new study says the colors found in modern birds’ eggs did not evolve independently, as previously thought, but evolved instead from dinosaurs. According to…
How did life arise on Earth? Rutgers researchers have found among the first and perhaps only hard evidence that simple protein catalysts – essential for…
New archaeological research from The Australian National University (ANU) has found that Homo erectus, an extinct species of primitive humans, went extinct in part because…
A new study argues that the greatest defining feature of our species is not ‘symbolism’ or dramatic cognitive change, but rather its unique ecological position…
For more than a century, scientists have understood that natural selection has profound effects on how an animal looks. Anole lizards that spend more time…
To fully understand biodiversity and how it is changing, you need to look near, far, and in-between, according to a new study. Researchers at Yale…
The evolution of Earth’s first animals more than 500 million years ago caused global warming, new research shows. Some 520-540 million years ago, animal life…
The mouth of today’s crocodilians inspires fear and awe, with their wide gape and the greatest known bite force in the vertebrate animal kingdom. However,…
Some of the earliest predators that patrolled the oceans over 500 million years ago are also some of the largest animals to have lived at…
