Roughly 140 million to 100 million years ago, the piece of land that is modern day Australia was located much further south on Earth. In fact, what is now Victoria was once within the polar circle, up to 80 degrees south of the equator and shrouded in dar

For centuries, scientists have observed that animals in warmer climates have longer limbs—a pattern known as Allen's Rule. Long attributed to the need to maintain body temperature, the precise mechanism that gave rise to this pattern has remained poorly

Researchers at Umeå University, Sweden, and Michigan State University, U.S., have discovered a type of molecule that can kill chlamydia bacteria, but spare bacteria that are important for health. The discovery opens the door for further research toward de

Why do cats generally live longer than dogs? New research suggests that longer lifespans of mammals like cats could be linked to their bigger brains and more complex immune systems.

An innovative imaging technique developed at Carnegie Mellon University reveals single bacterial cells leaving their biofilm community. Watching the bacteria in real-time at high resolution affords unprecedented views that advance the understanding of how

The biodiversity of Earth's oceans is disproportionately concentrated in coral reefs—the vibrant undersea ecosystems where thousands of known marine species reside.

They are large rafts that drift thousands of kilometers across the ocean surface, moving with the currents in an otherwise featureless marine environment. Tracked by satellites, the rudimentary floats—which may also be outfitted with long, submerged tails

A study published in the journal Cell marks the first reported instance of generative AI designing synthetic molecules that can successfully control gene expression in healthy mammalian cells.

Scientists have found that a mere 30 species of trees in the Cerrado—the world's largest and most floristically diverse savanna—account for nearly half of all its trees.

The North Korean government engages in unsustainable and illegal wildlife trade, which includes species protected under its own laws and poses a threat to biodiversity recovery in the region, finds a new study by UCL researchers.

A debate continues among scientists over whether tree composition in forests in eastern North America historically have been influenced more by climate or by cultural burning, which is the intentional and controlled use of fire by Indigenous people to man

Researchers led by Professor Erik van Nimwegen at the Biozentrum, University of Basel, have discovered a new mechanism in bacteria that controls their response to prevailing environmental conditions. They derived their theory from a simple yet interesting
