Environmental oxygen triggers loss of webbed digits

Free fingers have many obvious advantages on land, such as in locomotion and grasping, while webbed fingers are typical of aquatic or gliding animals. But both amphibians and amniotes—which include mammals, reptiles, and ...

A microscopic topographic map of cellular function

The flow of traffic through our nation's highways and byways is meticulously mapped and studied, but less is known about how materials in cells travel. Now, a team of researchers at the University of Missouri is challenging ...

Nuclear pore complex outer rings: No longer 'one size fits all'

In eukaryotic cells, the nucleus is walled off from the rest of the cell by the nuclear envelope. All transport into and out of the nucleus occurs via cylindrical channels called nuclear pore complexes (NPCs) that penetrate ...

How the cell protects itself

The cell contains transcripts of genetic material, which migrate from the cell nucleus to another part of the cell. This movement protects the genetic transcripts from the recruitment of "spliceosomes." If this protection ...

Detecting bacteria such as E. coli in minutes

A discovery by researchers at the School of Life Sciences at the University of Warwick offers a new technology for detecting bacteria in minutes by 'zapping' the bacteria with electricity.

New vulnerability found in major human viruses

Discovery of a new feature of a large class of pathogenic viruses may allow development of new antiviral medications for the common cold, polio, and other illnesses, according to a new study publishing June 11 in the open-access ...

New tool can pinpoint origins of the gut's bacteria

A UCLA-led research team has developed a faster and more accurate way to determine where the many bacteria that live in, and on, humans come from. Broadly, the tool can deduce the origins of any microbiome, a localized and ...

The cholera bacterium's 3-in-1 toolkit for life in the ocean

Bacteria are the most abundant form of life on Earth. The ocean is highly abundant with small particles and debris, some inert, some highly nutritious. But researchers want to know how bacteria differentiate between these ...

Keeping food safe from bacteria

NUS food scientists have found that a combination of lactic acid with food grade sodium hypochlorite is an effective sanitizer to process fresh organic vegetables.

How to develop affordable sensors using slime mold

Physarum polycephalum, which literally means "many-headed slime," is a slime mold that inhabits damp and dark habitats, such as decaying wood. Thanks to its ability to respond to stimuli such as light, chemicals and vibrations, ...

The deep learning dive: how cells regulate division

Combining tissue imaging and artificial intelligence, Hollings Cancer Center researchers at the Medical University of South Carolina probed deeper into how cell division cycles are regulated, in this study released online ...
