Connecting a star"s chemical composition and planet formation
Researchers from Penn's Department of Physics and Astronomy have developed a new method for better understanding the relationship between a star's chemical composition and planet formation. The study was led by recent graduate Jacob Nibauer for his s.....»»
The Anthropocene already exists in our heads, even if it"s now officially not a geological epoch
An international subcommittee of geologists recently voted to reject a proposal to make the Anthropocene an official new geological epoch, defined by humanity's enormous impact on the planet. Assuming some protests do not overturn the ruling, it will.....»»
Researchers discover key gene for toxic alkaloid in barley
All plants mediate their environmental interactions via chemical signals. An example is the alkaloid gramine produced by barley, one of the world's most widely-grown cereals. Gramine provides protection against herbivorous insects and grazing animals.....»»
Faintest known star system orbiting the Milky Way discovered
A team of astronomers led by the University of Victoria and Yale University has detected an ancient star system traveling around our galaxy named Ursa Major III / UNIONS 1 (UMa3/U1)—the faintest and lowest-mass Milky Way satellite ever discovered,.....»»

Extreme heat and ozone pollution: A call for targeted control strategies in China
Elevated surface ozone concentrations in China are posing a significant threat to both human health and crop yields. Extreme heat can greatly exacerbate ozone pollution through both complex chemical and physical processes. For example, extreme heat i.....»»
In a distant stellar system, the JWST sees the end of planet formation
Every time a star forms, it represents an explosion of possibilities. Not for the star itself; its fate is governed by its mass. The possibilities it signifies are in the planets that form around it. Will some be rocky? Will they be in the habitable.....»»
Life might be difficult to find on a single planet but may be obvious across many worlds
If we could detect a clear, unambiguous biosignature on just one of the thousands of exoplanets we know of, it would be a huge, game-changing moment for humanity. But it's extremely difficult. We simply aren't in a place where we can be certain that.....»»
Review: Withings Body Scan w/ segmental body comp, nerve activity, Apple Health, more
The most recent smart scale from Withings is so advanced the company calls it a “health station.” I’ve been testing the Withings Body Scan and its features like segmental body composition measurements, nerve activity, 6-lead ECG, and more, whic.....»»
Scientists discover how caterpillars can stop their bleeding in seconds
Blood is a remarkable material: it must remain fluid inside blood vessels, yet clot as quickly as possible outside them, to stop bleeding. The chemical cascade that makes this possible is well understood for vertebrate blood. But hemolymph, the equiv.....»»
Hubble captures the dramatic jets of a baby star
A new image from the Hubble Space Telescope shows the drama that unfolds as a new star is born......»»

New nearby mini-Neptune exoplanet discovered
An international team of astronomers reports the discovery of a new mini-Neptune exoplanet orbiting a nearby star. The newfound alien world, designated TOI-4438 b is about 2.5 times larger than the Earth. The finding was detailed in a paper published.....»»
Enhancing safety in green adipic acid synthesis: The role of EDTA stabilizer and microchannel flow technology
Adipic acid, a fundamental component in the manufacture of chemical fibers, nylon 66, engineering plastics, and various pharmaceutical, food, and chemical products, is commonly synthesized through a green process involving the oxidation of cyclohexen.....»»
Antarctic sea ice near historic lows: Arctic ice continues decline
Sea ice at both the top and bottom of the planet continued its decline in 2024. In the waters around Antarctica, ice coverage shrank to near-historic lows for the third year in a row. The recurring loss hints at a long-term shift in conditions in the.....»»
How many zebrafish constitute a school? "Three," say physicists
Physicists are also interested in fish—above all when they are researching the formation of structures. A research team from Heinrich Heine University Düsseldorf (HHU) and the University of Bristol (United Kingdom) has examined the schooling behav.....»»
Researchers develop numerical models to better understand long-term effects on lake ecosystems
Although numerous lakes around the world have been showing an increase in annual mean temperature over the last few decades, it still remains difficult to assess long-term warming-related impacts in water bodies with various physical and chemical pro.....»»
Hubble sees new star proclaiming its presence with cosmic light show
FS Tau is a multi-star system made up of FS Tau A, the bright star-like object near the middle of the image, and FS Tau B (Haro 6-5B), the bright object to the far right that is partially obscured by a dark, vertical lane of dust. These young objects.....»»
