New research shows that the Vikings traveled more than 6,000 kilometers to the Arctic to hunt for walrus. DNA analyses reveal that walrus ivory from Greenland was brought to Europe and probably as far as the Middle East [M1] via extensive trade networks. Read more ›

Asteraceae, a family of flowering plants which includes daisies, sunflowers and asters, are the most diverse group of flowering plants in the world. This plant family comprises around 34,000 species, some of which are well-known, such as artichokes, chamomile, dahlias and lettuce. An international research team has now compiled and analyzed a new global database on the distribution and evolutionary history of all Asteraceae species. The researchers found that an... Read more ›

Sea robins are unusual animals with the body of a fish, wings of a bird, and walking legs of a crab. Now, researchers show that the legs of the sea robin aren't just used for walking. In fact, they are bona fide sensory organs used to find buried prey while digging. Read more ›

A 2020 microlensing event was caused by a planetary system with an Earth-like planet and brown dwarf. The star type was uncertain. The team has determined that the star is a white dwarf, a system resembling what our sun-Earth system will look like in 8 billion years. The good news: the planet survived its star's red giant phase, so maybe Earth will too. The bad news: it's still uninhabitable. Read more ›

Glioblastoma is the most common and most aggressive primary brain tumor, with an average survival after diagnosis of less than two years, and against which current treatments remain ineffective. In recent years, immunotherapies have given patients renewed hope, albeit with relatively modest success. A team has succeeded in identifying a specific marker on the surface of tumour cells, and in generating immune cells carrying an antibody to destroy them. Furthermore,... Read more ›

Results from a preclinical study in mice and a collaborative clinical study in patients show that the type 2 immune response -- associated with parasitic infection and thought to play a negative role in cancer immunity -- is positively correlated with long-term cancer remission. Read more ›

Scientists successfully tested a new way to produce sustainable jet fuel from lignin-based agricultural waste. The team's research demonstrated a continuous process that directly converts lignin polymers, one of the chief components of plant cells, into a form of jet fuel that could help improve performance of sustainably produced aviation fuels.

Researchers have studied how nanoplastic affects aquatic organisms in lakes and rivers. The results are surprising and the researchers are the first to show that some species are being wiped out, while others -- such as cyanobacteria that contribute to algal blooms -- are completely unaffected.

In a surprise finding, astronomers using NASA's Hubble Space Telescope have discovered that the blowtorch-like jet from a supermassive black hole at the core of a huge galaxy seems to cause stars to erupt along its trajectory. The stars, called novae, are not caught inside the jet, but apparently in a dangerous neighborhood nearby. Read more ›
