As Negotiators Struggle to Advance a Plastics Treaty, Iran War Underscores the Urgency
As nations met this week in Bangkok for informal meetings on a United Nations plastics treaty, more than 70 developing countries supported addressing all causes and drivers of pla…
Black holes may grow quietly alongside galaxies even without violent mergers
Astronomers analyzed 2,435 galaxies hosting actively feeding black holes using data from the Dark Energy Spectroscopic Instrument (DESI). Among them, they identified 546 "bulgeles…
NASA’s DAVINCI Probe Can Stand the Heat
The engineering development unit for NASA’s DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) probe is photographed prior to a major thermal eva…
Q&A: How will quantum computers change society?
Once called a "pipe dream," quantum computers are now approaching practical use. Companies and research institutes around the world are in fierce competition to develop this techn…
New algorithm makes maps of gene activity easier to compare while preserving cell-level detail
Spatial transcriptomics can reveal where thousands of genes are active across a tissue, creating molecular maps at single-cell resolution. But comparing two such maps is difficult…
Animals may have evolved vastly earlier than fossil evidence suggests
The earliest animals may have evolved hundreds of millions of years before their first unmistakable fossils appear in the fossil record, according to a new study led by the Univer…
Physicists who uncovered the first particle accelerator were honored with a Nobel Prize 75 years ago
While scientists are known for their dedication to their research, crawling on the floor to avoid electrocution for the sake of a measurement seems a little excessive. But this is…
Fluorescent test speeds screening of thousands of enzyme variants that modify plant compounds
Many natural plant compounds have promising health-related properties, but their poor water solubility can limit how effectively they are absorbed and used. In previous work, rese…
Millions of years of evolution guide AI search for pollution-fighting enzymes
Databases around the world contain information on millions upon millions of enzymes that have the potential to degrade pollutants like plastic. Scientists at Murdoch University's …
Enzymes become sturdy beads that could support more sustainable chemical production
Thanks to enzyme-based biocatalysis, an enormous range of pharmaceutical active ingredients and other complex molecules can be synthesized in an environmentally friendly manner. R…

NASA Campaign Explores Clouds Spawned by Wildfires
The Wildhorse grass fire in eastern Idaho erupted with a massive pulse of smoke. No one had expected it, but the wildfire had launched what’s known as a pyrocumulonimbus cloud, or…
How stars shine: Infrared observations expose gaps in models of how stars distribute their light
Astronomers using Georgia State University's Center for High Angular Resolution Astronomy (CHARA) Array have found that nearby stars darken toward their edges more strongly at nea…
Q&A: Why are red squirrels endangered—and can we save them?
The red squirrel was once a familiar sight across Britain. Today, it has disappeared from much of its former range. Dr. Kat Hamill, senior lecturer in zoology at Nottingham Trent …

Groundbreaking tests at NASA’s Langley Research Center in Hampton, Virginia, are paving the way for new wind tunnel capabilities for designing the aircraft technologies of the fut…
What space travel teaches us about sleep and circadian rhythms
On Earth, most of us rarely have to think about the signals that keep our internal clocks aligned. The sun rises, daylight changes, darkness arrives and morning comes again.
NASA Opens Applications for Next Class of Flight Directors
NASA is seeking leaders for one of the most esteemed positions on Earth for human spaceflight: flight director in mission control at the agency’s Johnson Space Center in Houston. …
New research shows how water would behave on the moon
As humanity looks toward future bases on the moon, plant cultivation will be critical for sustaining life there. Plants can provide food, oxygen, medicine, water purification and …
A 'reality check' for lab-grown human embryo models
University of Sydney researchers have developed a new way to test how closely lab-grown biological models resemble real human embryos, finding that while some models perform well,…
Multitasking in magenta: Colored solar panels could help farms grow crops and generate electricity on shared land
Broccoli grown under magenta solar panels absorbed sunlight more efficiently than plants grown out in the open, according to a study to be published Oct. 2 in Cell Reports Physica…
