Yale researchers report that Caribbean anole species living deep in closed forest canopies raised their heat tolerance by about 2 degrees Celsius over a decade, while species in open or forest-edge habitats changed little. The team links the difference to behavioral thermoregulation and cautions that such adaptation has an eventual ceiling.
Modeling led by Viola Bocchi suggests dense, metal-poor young clusters detected by JWST, including the Cosmic Gems arc and Firefly Sparkle, could have produced intermediate-mass black hole seeds able to grow into supermassive black holes. The estimates rely on simulations, and JWST did not observe these black holes.
Archaeologists reexamined almost 3,000 flint artifacts excavated at Heliopolis in 1905–1906 and identified a workshop where skilled knappers made blades beyond local needs. They argue village-level craft specialization existed before Egypt's state formed around 3000 B.C.
A study using 2001-2023 satellite records for 67,248 converted patches found that tree planting on nonforested land was linked to an average 26% rise in fire occurrence per hectare yearly and 23% more expected burned area per fire. Increases were largest in temperate conifer regions.
The upgraded LHCb experiment at CERN's Large Hadron Collider has yielded the first evidence of a decay called Bd to mu mu, a process predicted to occur roughly once per 10 billion beauty particles. The result reaches 3.2 sigma, which physicists say needs further data before the five-sigma level required for a discovery.
Early Texas A&M AgriLife Research findings suggest heat changes mealybug feeding, potentially explaining why some pasture mealybug outbreaks cause worse damage. The invasive pest, first confirmed in Texas in July 2025, has reached 114 counties and threatens forage for the state's $15.5 billion cattle industry.
Concordia researchers report genomic evidence that Porticoccus arcticus may use acetone carboxylation to incorporate carbon dioxide while also capturing light energy via proteorhodopsins. The bacterium reached up to 9% of detected bacteria at some sites in the Beaufort Sea, though warming Arctic implications remain unknown.
Sociologists have developed and validated multi-item survey scales built on W.E.B. Du Bois' theory of double consciousness, covering its three constructs: the veil, second sight and two-ness. The paper describing the measures' development and validation was published in the Du Bois Review.
New simulations indicate that on an irregular asteroid, the side struck by an X-ray burst from a nuclear detonation strongly affects deflection, with one case giving 3.9 versus 0.8 millimeters per second. The model combined high-fidelity codes and ran over 1,600 times faster, though it cannot yet predict breakup of the entire asteroid.
An eight-week trial in 82 adults with prediabetes found daily Hass avocado and mango intake was linked to improved flow-mediated dilation and central blood pressure versus calorie-matched carbohydrate foods, without weight gain. Supported by mango and avocado boards, it tracked risk markers rather than long-term heart outcomes.
A Cold Spring Harbor Laboratory mouse study links maternal immune activation during pregnancy to placental damage and autism-like traits found only in male offspring. The researchers say the results do not establish the same mechanism in humans and may point to earlier developmental origins.
Testing museum specimens from Brazil's Atlantic Forest, researchers found chytrid fungus arrived around the same time as severe amphibian declines at Boracéia in the late 1970s and early 1980s. Surveys in 2022–2024 found most historical species had recovered, but five were not located.
Mouse experiments reported in Nature Neuroscience suggest fear can make hippocampal representations of safe and dangerous settings overlap, possibly aiding faster threat recall. The McGill and University of Toronto researchers say this may help explain anxiety and PTSD, but human studies are still needed.
Scientists are attaching solar-powered radio tags to nearly 1,750 monarch butterflies this year to map their migration routes and stopover sites, with detections of roughly 175 tagged butterflies in Mexico. The project also highlights habitat loss, pesticides and climate change as threats.
A CIRES-led Nature Communications study projects that with moderate climate mitigation and no new fire adaptations, U.S. structural fire losses would nearly triple by 2060, with up to 449,100 buildings damaged or destroyed. It finds the largest risk increase in the central U.S. and highest risk in vulnerable western communities.
Experiments with two male carrion crows at the University of Tübingen found the birds learned to switch between calling and pecking, but shifting to a vocalization slowed responses compared with repeating a call. The researchers suggest this vocal-specific switch cost reflects greater cognitive demands of calling.
A study of ERA5-Land data from 1950–2024 found compound drought–heat wave events in Oman were most frequent in central-western and northern regions, with 2023–2024 exceptionally severe. Drought frequency rose significantly in about 60.32% of grid cells, while heat-wave and compound trends varied geographically.
Research from NYU Abu Dhabi using Danish population records from 2018 to 2024 found that subsidized Ozempic treatment for diabetes raised the probability of employment by 4.1 percentage points, while self-paying Wegovy users who were already employed worked an additional 29.7 hours per quarter.
Research published in PNAS found that certain soil microbes in Antarctica seem to occur nowhere else on the planet, contradicting the view that microbes disperse easily. Lab tests also showed Antarctic bacteria blocking clinically important organisms, and warming may alter these communities.
A Queen's University Belfast-led team reports two asteroids and a candidate as long-lived members of Neptune's trailing Trojan cloud, identified in early Vera C. Rubin Observatory data. Researchers say Rubin's depth and sky coverage let them double the known objects in this population.
