Pathogens may have facilitated the evolution of warm-blooded animals

Animals first developed fever as a response to infections: the higher body temperatures primed their immune systems. At the time, 600 million years ago, virtually all animal species were cold-blooded. They had to spend long periods of time in warm areas of their habitat to achieve fever-range body temperatures. A researcher believes that pathogens may be the reason why warm-blooded creatures first emerged.

Ear-generated Doppler shifts in bat biosonar

A new study demonstrates that the ears of bats come with a 'built-in ambulance' that creates the same physical effect as the sound of an ambulance passing by. Researchers think the study of ear-generated Doppler shifts in bat biosonar could give rise to new sensory principles that could enable small, yet powerful sensors.

Feathers came first, then birds

New research suggests that feathers arose 100 million years before birds -- changing how we look at dinosaurs, birds, and pterosaurs, the flying reptiles.

Oldest flaked stone tools point to the repeated invention of stone tools

A new archaeological site discovered by scientists working in Ethiopia shows that the origins of stone tool production are older than 2.58 million years ago. Previously, the oldest evidence for systematic stone tool production and use was 2.58 to 2.55 million years ago.

Physicists can predict the jumps of Schrödinger's cat (and finally save it)

Researchers have figured out how to catch and save Schrödinger's famous cat, the symbol of quantum superposition and unpredictability, by anticipating its jumps and acting in real time to save it from proverbial doom.

CRISPR baby mutation significantly increases mortality

Six months ago, a Chinese scientist announced that he had edited the genomes of two babies born last year. The germline edits with CRISPR-Cas9 supposedly changed the CCR5 gene to prevent HIV from invading immune cells. An analysis of records in the U.K. Biobank shows that having two copies of this mutation is associated with a 21 percent increase in mortality.

Edible insects? Lab-grown meat? The real future food is lab-grown insect meat

Livestock farming is destroying our planet. It is a major cause of land and water degradation, biodiversity loss, acid rain, coral reef degeneration, deforestation -- and of course, climate change. Plant-based diets, insect farming, lab-grown meat and genetically modified animals have all been proposed as potential solutions. Which is best? All of these combined, say researchers.
