Tuberculosis drug discovery gets smarter with AI‎

When researchers screen potential tuberculosis drugs, they often end up with too many options. Some look promising but later prove to be costly dead ends. "We might get thousands of compounds from a screen and then have to decide which one are we going to work on?" said James Sacchettini, Ph.D., the Rodger J. Wolfe-Welch Foundation Chair in Science, Texas A&M AgriLife Research scientist and professor in the Texas A&M College of Agriculture and Life Sciences Department of Biochemistry and Biophysics and College of Arts and Sciences Department of Chemistry.

Herbularyo card game blends Filipino folklore and organic chemistry‎

Medicinal plants have long been a cornerstone of Philippine traditional medicine, dating back generations. Tawa-tawa, a low-growing herb that thrives in open grasslands, is a valued supplementary treatment for dengue; the gel of the succulent aloe vera can help soothe a scraped knee; boiled guava leaves help disinfect wounds; tea from yerba buena helps relieve minor aches and pains; and ampalaya helps manage diabetes.

Amazon soy pact collapse could add 1.4 million hectares of deforestation by 2036‎

The collapse of a landmark Amazon soy pact will drive at least 1.4 million hectares (3.5 million acres) of extra deforestation in Brazil over the next decade, releasing carbon emissions equal to Canada's annual output, according to an analysis published Thursday.

Fatal car crashes in the US rise the day after a major mass shooting incident, finds new study‎

Mass shooting incidents and car crashes may seem like two unrelated incidents, but a recent study has uncovered that there might be an unexpected link. Every year, more than a hundred mass shootings take place across the United States, many leaving behind four or more lives lost. In the aftermath, the tragedy quickly spreads across every avenue of media, from newspaper headlines and TV news to social media feeds and even online searches. This constant stream of coverage can leave people feeling anxious, distracted, and emotionally overwhelmed.

How Gravity from Entropy theory connects the second law of thermodynamics with the emergence of cosmic structure‎

A new study by Queen Mary University of London mathematician Professor Ginestra Bianconi proposes a new perspective on one of the deepest questions in modern physics: How can the universe become increasingly structured and complex while still obeying the second law of thermodynamics?

The Large Hadron Collider is being upgraded so that it can unlock the secrets of the Higgs boson‎

Deep beneath the French-Swiss border, the world's largest scientific instrument has fallen silent. After years of smashing protons together at nearly the speed of light, CERN's Large Hadron Collider (LHC) has stopped operations and entered a long shutdown.

Underwater oxygen loss threatens earth's stability, researchers warn‎

A new review in Limnology and Oceanography led by scientists at UC San Diego's Scripps Institution of Oceanography warns that the rapid loss of oxygen from the ocean and other aquatic ecosystems is pushing Earth toward an "unsafe space," with consequences that could be irreversible on human timescales.

Wild snapdragons paint themselves in subtle shades to attract bees‎

Just as careful blending of eye shadow can make a difference to our looks, a recent study has shown how flowers go to considerable trouble to fine-tune their shades. In the relentless competition to attract bees, a slight edge can make the difference between life and death for a gene.

Researchers identify class of 'oddball' meteorite that killed the dinosaurs‎

A rare CO chondrite meteorite was the probable impacter that struck Earth 66 million years ago, wiping out 75% of Earth's species, including nonavian dinosaurs. These findings are published in Science Advances. Researchers at the University of British Columbia (UBC), Paris, Brussels and Vienna, used advanced nickel isotope analysis of samples to narrow down the composition of the deadly Cretaceous-Paleogene meteorite.
