Much of organic chemistry, including the type used to create and alter medicinal drugs, relies on modifying carbon bonds. Rice University's Julian West has been developing a less expensive, faster and more environmentally friendly way to catalyze…
Scientists, clinicians, seed companies and others may soon have a new tool in their toolkit for detecting bacterial pathogens, thanks to a new study by researchers in Penn State's College of Agricultural Sciences. The research—published in Journal…
Some of us now use generative artificial intelligence (gen AI) to talk through difficult feelings. We may ask a chatbot to write an email or plan a vacation, but we also tell it that we have had a rotten day or feel anxious about a presentation.
Very small biological samples and even individual biomolecules can now be examined under near-physiological conditions with high confidence at the BESSY II infrared beamline using a newly validated and improved technique: nanoscale infrared (IR)…

When it rains, traveling waves appear on steep asphalt pavement, slowly making their way down the slope. Because these so-called "roll waves" propagate without deforming and are typically characterized by abrupt discontinuities, they play an…
Spekboom (Portulacaria afra) is an easy-to-grow succulent shrub, small tree or hedge. In the wild, it grows naturally as tall as five meters (16 feet) on steep slopes and rocky hillsides in the Karoo and Eastern Cape regions of South Africa, where…

The dinosaurs were once considered reptilian, but the new results suggest we may need to rethink their evolution
Both the president and Secretary of Health and Human Services Robert F. Kennedy, Jr., have made numerous false claims about the vaccines’ efficacy and safety
The crater site, before and after impact NASA/Mark S. Robinson et al. 2026 A newly formed crater on the moon is teaching us about our nearest neighbour’s complex geology. The crater, formed by an asteroid impact in 2024, is the largest that we’ve…
The amount of dust in the atmosphere has fallen, which is good for our lungs, but is a loss for ecosystems that depend on wind-borne nutrients
Tyrannosaurus rex was probably a warm-blooded predator Orla/Shutterstock The world’s most famous dinosaur, Tyrannosaurus rex, was probably warm-blooded like birds and mammals, new evidence, obtained from 66-million-year-old tooth enamel, suggests…
Yet more readers share their insights from their own four-legged friends – and one proposes a more general theory
If every ship on the planet were hauled out of the water, how much would global sea levels change, and how quickly? How different would Earth be if anaerobic life were the only life form, and could it have become sentient?
