Quantum tunneling could drive random DNA mutations, says new study

DNA mutates regularly, for better or worse, driving both evolution and disease. Researchers at the University of Surrey have now found evidence that some of these spontaneous mutations could be caused by the spooky realm of quantum mechanics.

InBio makes strong progress toward CRISPR-edited hypoallergenic cats

A single protein called Fel d 1 is responsible for the lion's share of human cat allergies, but a company called InBio says its initial research indicates a promising possibility that this protein can be eliminated safely using CRISPR gene editing.

RNA “evolution” breakthrough offers new clues on the origins of life

Researchers at the University of Tokyo have created an RNA molecule that can not just replicate, but “evolve” into a diverse range of more complex molecules. This find could plug a major gap in the puzzle of how life on Earth began.

“Mother of stem cells” boast better efficiency when they slow down

Researchers have found that the “mother” of stem cells, known as totipotent stem cells, have a much slower rate of DNA replication, which helps improve their differentiation efficiency. This could lead to major breakthrough for regenerative medicine.

Largest bacterium ever discovered is longer than a housefly

Biologists have discovered the largest bacterium ever found, with a single cell measuring a mammoth 2 cm long. Visible to the naked eye, this new species has bizarre characteristics that make it like a missing link in the evolution of complex cells.

Lead ammunition appears to be chronically poisoning American eagles

A new study has found that nearly half of all bald and golden eagles in the USA suffer from chronic and/or acute lead poisoning, which the research team believes is the result of these birds scavenging the remains of animals shot with lead bullets.

Study suggests that most fishes communicate with sound

We generally don't think of fish as being a vocal bunch – after all, anglers don't typically use "fish calls" to lure them in. According to a new study, however, approximately two-thirds of all fish species probably use sound to communicate.

Newly discovered “oral plug” keeps whales from drowning as they dine

How do whales gulp down huge amounts of water and krill without drowning themselves with every mouthful? Researchers have now discovered an “oral plug” in the throats of some species that blocks either their airways or esophagus as needed.

Glowing nanoantennas made of DNA spy on proteins in action

Researchers in Canada have developed a new tool that can let scientists examine proteins more closely, aiding study of disease and drug development. The team used DNA to create nanoantennas that fluoresce in response to different protein functions.

Schools of mollie fish “do the wave” to evade predators

We've all seen sports spectators performing "the wave," where people stand up then sit back down to simulate a wave moving through the stadium. Well, schools of mollies have been found to perform a similar action, in order to keep from being eaten.
