Ancient, lost, mountains in the Karoo reveals the secrets of massive extinction event

A researcher studied the fossil-rich sediments present in the Karoo, deposited during the tectonic events that created the Gondwanides, and found that the vertebrate animals in the area started to either go extinct or become less common much earlier than what was previously thought.

Study reshapes understanding of climate change’s impact on early societies

A new study linking paleoclimatology -- the reconstruction of past global climates -- with historical analysis shows a link between environmental stress and its impact on the economy, political stability, and war-fighting capacity of ancient Egypt.

Assessment shows metagenomics software has much room for improvement

A recent critical assessment of software tools represents a key step toward taming the 'Wild West' nature of the burgeoning field of metagenomics.

Scientists determine source of world’s largest mud eruption

More than 11 years after the Lusi mud volcano first erupted on the Indonesian island of Java, researchers may have figured out why the mudflows haven't stopped: deep underground, Lusi is connected to a nearby volcanic system.

Clues to the Innate Drug Resistance of a Cocoa-Fermenting Pathogen

At first glance, the yeast Candida krusei seems as innocuous as microbes come: it’s used for fermenting cocoa beans and gives chocolate its pleasant aroma. But it’s increasingly being found as a pathogen in immunocompromised patients — and C. krusei infections aren’t always easy to cure.

Toward efficient high-pressure desalination

One of the biggest operational challenges for desalination plants is the fouling of membranes by microbes. New research suggests a novel approach to reducing the rate of fouling, and thus improving desalination plant efficiency.

Whales and dolphins have rich ‘human-like’ cultures and societies

Whales and dolphins (cetaceans) live in tightly-knit social groups, have complex relationships, talk to each other and even have regional dialects -- much like human societies. A major new study has linked the complexity of Cetacean culture and behavior to the size of their brains.

Giant sea bass worth more alive as undersea wonders than as commercial catch

An investigation of the different economic values of giant sea bass finds they are worth more alive as undersea wonders than as commercial catch.

Gutters teem with inconspicuous life

Scientists have shown that Parisian street gutters are oases of microscopic life, home to microalgae, fungi, sponges, and mollusks. Grouped into communities, these microorganisms may help clean rainwater and urban waste by decomposing solid debris and pollutants. A deeper understanding of the role and composition of these communities could help elucidate the services rendered by gutter ecosystems. The researchers' findings are the first to reveal the unsuspected biodiversity of microscopic life in Paris city streets.

Worms reveal secrets of aging

Investigators have identified a new molecular pathway that controls lifespan and healthspan in worms and mammals. Researchers have shown that worms with excess levels of certain proteins lived longer and healthier than normal worms. In addition, mice with excess levels of these proteins demonstrated a delay in blood vessel dysfunction associated with aging. The study has major implications for our understanding of aging and age-associated disorders.
