For The Better

As early as 18,000 years ago, humans in New Guinea may have collected cassowary eggs near maturity and then raised the birds to adulthood, according to an international team of scientists, who used eggshells to determine the developmental stage of the …

Previously published solar exposure guidelines for optimal vitamin D synthesis based on a study of skin samples may need to be revised.

Ice melange, a slushy mixture of snow and ice chunks, can heal large rifts in Antarctica’s ice shelves. Researchers found that a thinning of ice melange may have enabled a Delaware-sized iceberg to break off from the Larsen C ice shelf in 2017. A new a…

The rise of dinosaurs coincided with environmental changes driven by major volcanic eruptions over 230 million years ago, a new study reveals.

N95 respirators offer the best protection against wildfire smoke and other types of air pollution, performing better than synthetic, cotton and surgical masks. N95s were so effective in the lab experiments that the researchers estimate their widespread…

Researchers describe how withdrawal from nicotine, methamphetamine and cocaine alters the functional architecture and patterns in the brains of mice, compared to control animals, a key to developing addiction treatments.

Researchers suggest that advances in breast cancer prevention research have resulted in new and innovative opportunities to modify breast cancer risk and potentially reduce breast cancer incidence and mortality.

A type of drug already used to treat obesity and Type 2 diabetes, when taken six months prior to the diagnosis of COVID-19, was associated with a decreased risk of hospitalization, respiratory complications and death in COVID-19 patients with Type 2 di…

In many North American lakes, a tiny clawed creature has become a big bully. The invasive rusty crayfish roams lakebeds, snapping up snails, bivalves, and water plants, cutting off food supplies for native crayfish and other animals. And when they’re f…

Complex autoimmune diseases affecting various organ systems remain one of the greatest medical challenges in spite of immense advances in treatment. In particular, the diffuse symptoms at the early stage of complex autoimmune diseases make it hard to d…

Researchers want to image proteins with unprecedented precision — and thus gain insights into the molecular pathogenesis of Alzheimer’s. This should pave the way for an earlier diagnosis of the dementia disorder via a simple blood test. A successful p…

Tomoscopy is an imaging method in which three-dimensional images of the inside of materials are calculated in rapid succession. Now a team has achieved a new record: with 1000 tomograms per second, it is now possible to non-destructively document very …

Although female giraffes have closer ‘friends’ than male giraffes, male giraffes have more ‘acquaintances’ than females, according to new research. The study demonstrates that giraffes form a complex multilevel society that is driven by differences in …

Using machine learning and simulations of giant impacts, researchers found that the planets residing in the inner solar system were likely born from repeated hit-and-run collisions, challenging conventional models of planet formation.
