Mysterious little red jellies: A case of mistaken identity

Little red jellies are commonplace near the deep seafloor in Monterey Bay and around the world. Most of them are small—less than five centimeters (two inches) across—and a ruddy red color, but we know little else about ...

Surveying all the proteins on a neuron's surface

Scientists have found a new way to home in on the proteins covering a particular cell's surface. The feat offers insight into how brain cells form intricate networks during development.

Plant organ growth is not so different from animals

For a long time, researchers assumed that cell death occurs mainly during animal organ growth, but not in plant organs. A research group led by Hannele Tuominen from UPSC has now demonstrated that the death of certain cells ...

Sanitary care by social ants shapes disease outcome

Sanitary care in ants to fight disease is known to improve the wellbeing of the colony, yet it has been unclear how social disease defense interferes with pathogen competition inside the individual host body. In their recent ...

Sea lions yawn due to anxiety

Researchers have analysed these animals for 14 months, concluding that the frequency of their yawns increases immediately after a social conflict among members of the group.

French oyster farmers fume as norovirus shuts down sales

Several oyster farmers along France's Atlantic and Mediterranean coasts have been forced to halt sales since December after their sites were contaminated by the highly contagious norovirus, which they blame on overflowing ...

Lessons on how to effectively tackle insect invasions

Kenyan food production and grazing land is under threat from a huge desert locust invasion. The insects are currently in two counties in northern Kenya and are now spreading to other Kenyan regions including Meru, Laikipia, ...

Fins and limbs tell evolutionary tale

About 400 million years ago, our early ancestors took their first hesitant steps out of the primordial seas on to land.

Hands off our grasslands

In the north eastern Free State, a 60 km green corridor is being created that will link the upper Wilge Protected Environment to the Sneeuwberg.

Changing the leopard's spots

Since wildlife poaching in Africa became a critical conservation issue, Chinese people have been portrayed as ruthless in the apparent pursuit of wildlife body parts. The Africa-China Reporting Project in Wits Journalism ...

How grass dances with fire

There's a long-held myth that Johannesburg is the globe's largest urban forest, resplendent with an annual purple Jacaranda show. But before the planting of these (alien) trees for timber during the Gold Rush in the 19th ...

Black rhino population shows steady growth

Good news stories can be hard to come by in an era of extinction, but the steady improvement in the fortunes of the black rhino is one of those stories.
