- 22/7/6 19:33
As it captivated people around the world, the January eruption of the Hunga Tonga-Hunga Ha'apai volcano gave scientists a once-in-a-lifetime chance to study how the atmosphere works, unlocking keys to better predict the weather and changing climate.
Scientists demonstrate machine learning tool to efficiently process complex solar data
- ScienceDaily
- 22/7/6 19:33
Big data has become a big challenge for space scientists analyzing vast datasets from increasingly powerful space instrumentation. To address this, a team has developed a machine learning tool to efficiently label large, complex datasets to allow deep learning models to sift through and identify potentially hazardous solar events. The new labeling tool can be applied or adapted to address other...
Psoriasis: Study lays foundation for new treatment strategy
- ScienceDaily
- 22/7/6 19:33
About one third of those who suffer from psoriasis develop inflammation in their joints (psoriatic arthritis) as a result of the chronic skin condition. A research team has now discovered a key starting point for inhibiting inflammation in both psoriasis and psoriatic arthritis. The researchers' findings may form the basis for developing new treatment, diagnostic and prevention strategies.

Shedding new light on dark matter
- ScienceDaily
- 22/7/6 19:32
A team of physicists has developed a method for predicting the composition of dark matter -- invisible matter detected only by its gravitational pull on ordinary matter and whose discovery has been long sought by scientists.
Case solved: The biosynthesis of strychnine elucidated
- ScienceDaily
- 22/7/6 19:32
A research team has disclosed the complete biosynthetic pathway for the formation of strychnine in the plant species Strychnos nux-vomica (poison nut). The researchers identified all genes involved in the biosynthesis of strychnine and other metabolites and expressed them in the model plant Nicotiana benthamiana. This enabled them to show that these extremely complex and pharmacologically...
Rampant wildfires once led to global mass extinction, scientists say. Can it happen again?
A long time ago, the carbon was rock, buried in the earth as securely as a secret. Then an environmental catastrophe of unprecedented scale began. The rocks burned, and the atoms inside them disassembled into carbon dioxide and other greenhouse gases.
New disease strikes Michigan trees. Arborists don't know how to treat it
A mysterious invasive disease has hit a stand of southeast Michigan trees, adding to a long list of threats faced by state forests.
Medicinal knowledge vanishes as Indigenous languages die
DAVOS, SWITZERLAND—
Uldarico Matapí Yucuna, 63, is often called the last shaman of the Matapi, an Indigenous group of fewer than 70 people living along the Mirití-Paraná River in the Colombian Amazon rainforest. His father was a shaman and taught him ancestral knowledge, including how to use plants to treat all kinds of maladies. But Uldarico rejects the title because...
