Researchers discover how microbes survive in freezing conditions

Most microbial researchers grow their cells in petri-dishes to study how they respond to stress and damaging conditions. But, with the support of funding from NASA, researchers in LSU's Department of Biological Sciences tried ...

Elephants know what it means to point, no training required

When people want to direct the attention of others, they naturally do so by pointing, starting from a very young age. Now, researchers reporting in Current Biology on October 10 have shown that elephants spontaneously get ...

Pulp friction cleans up 'Brockovich' chemical

A byproduct of the manufacture of pulp using the sulfite process for making paper, sodium lignosulfonate, can be used to immobilize and soak up toxic chromium compounds from soil and water, according to research published ...

As sea level rises, Everglades' freshwater plants perish

Just inland from the familiar salt-loving mangroves that line the Southern tip of the Florida Peninsula lie plant communities that depend on freshwater flowing south from Lake Okeechobee. These communities provide critical ...
