Biological activity alters the ability of sea spray to seed clouds

Ocean biology alters the chemical composition of sea spray in ways that influence their ability to form clouds over the ocean. That's the conclusion of a team of scientists using a new approach to study tiny atmospheric particles ...

Delivering a virus that gets rid of house flies

The house fly is often considered merely a nuisance. But these flies are capable of transmitting animal and human pathogens that can lead to foodborne diseases, including Escherichia coli, Salmonella, and Shigella bacteria.

Whale's streaming baleen tangles to trap food

Many whales filter food from water using racks of baleen plates in their mouths, but no one had ever investigated how baleen behaves in real life. According to Alexander Werth from Hampden-Sydney College, baleen was viewed ...

New device traps particulates, kills airborne pathogens

A new device called a soft x-ray electrostatic precipitator protected immunocompromised mice from airborne pathogenic bacteria, viruses, ultrafine particles, and allergens, according to a paper published online ahead of print ...

New biochip technology uses tiny whirlpools to corral microbes

Researchers have demonstrated a new technology that combines a laser and electric fields to create tiny centrifuge-like whirlpools to separate particles and microbes by size, a potential lab-on-a-chip system for medicine ...

Rare form of active 'jumping genes' found in mammals

Much of the DNA that makes up our genomes can be traced back to strange rogue sequences known as transposable elements, or jumping genes, which are largely idle in mammals. But Johns Hopkins researchers report they have identified ...
