Dome-headed dinosaur species discovered in Montana
The discovery of Brontotholus harmoni, a new dome-headed dinosaur species, in Montana's Two Medicine Formation has provided paleontologists with five distinct fossils, including a prominent skull dome, according to a study in the Zoological Journal of the Linnean Society. The research places the plant-eating Brontotholus on a separate evolutionary branch, challenging previous assumptions about pachycephalosaurid relationships and highlighting the complexity of ancient dinosaur ecosystems.

Ancient foot fossil linked to primitive human relative
 
This undated picture released by Institute of Human Origins at Arizona State University shows part of the juvenile jawbone of the ancient human relative Australopithecus deyiremeda discovered in Afar Region, in Ethiopia, on the ground before being collected. Newly discovered fossils, including a jawbone with 12 teeth, prove that a mysterious foot found in Ethiopia in 2009 belongs to a little-known, recently named ancient human relative who lived alongside the species of the famous Lucy, scientists said on November 26, 2025.

Scientists have identified the 3.4 million-year-old Burtele foot fossil as belonging to Australopithecus deyiremeda, a species that lived alongside the more well-known Australopithecus afarensis. This discovery, detailed in Nature, suggests that multiple hominin species coexisted and had different adaptations for bipedality and diet.

Supermassive black hole flare created ultrafast wind
Astronomers have observed a supermassive black hole flare in the galaxy NGC 3783 that triggered an ultrafast outflow, with winds reaching 19% of the speed of light. "For the first time, we've seen how a rapid burst of X-ray light from a black hole immediately triggers ultra-fast winds, with these winds forming in just a single day," said astronomer Liyi Gu.

Genetic research links China's Bo people to hanging coffins
The Bo people, known for the ancient practice of hanging coffins on cliffs in southern China, have been traced through DNA analysis to modern descendants in Yunnan province. The study, published in Nature Communications, reveals that the Bo did not vanish as previously thought, but have maintained their distinct culture for 3,000 years. The research highlights the Bo's connections to Neolithic coastal populations and the cultural exchanges in the region.

Tiny turbulent whirls, heat loss drive Arctic Ocean flow
 
SVALBARD, ARCTIC OCEAN - JULY 23: A view of Svalbard and surrounding glaciers during the 4th National Arctic Scientific Research Expedition on Arctic Ocean on July 23, 2024. Turkiye's fourth National Arctic Scientific Research Expedition, comprising an 11-member team, identified the decreasing sea ice due to global climate change through sampling, evaluation, observation and unmanned aerial vehicles. Under the auspices of the Turkish Presidency and Ministry of Industry and Technology, and coordinated by TUBITAK MAM Polar Research Institute, scientists observed the a decrease in sea ice as much as 1 in 8 of Turkiye's size from June 2023 to 2024.

Research published in AGU Advances highlights the role of tiny turbulent whirls and heat loss in driving the vertical circulation of the Arctic Ocean. As climate change accelerates sea ice melt and increases the influx of warmer water, the balance between surface fluxes and turbulence is expected to shift, potentially impacting the Atlantic Meridional Overturning Circulation, which is crucial for weather patterns in Europe and North America.

Social media is rife with misinformation about epilepsy
Nearly half the TikTok videos about epilepsy promote false information, some of which is potentially harmful, but 90% of content from traditional medical professionals is generally accurate, according to a study presented at the American Epilepsy Society's annual meeting. Another study found that much of the information on various platforms about cannabidiol therapy for epilepsy is either inaccurate or insufficient. Videos and content with inaccurate or misleading information have the highest engagement, researchers reported.

NIH grant to fund pediatric heart pump development
Researchers at Penn State University have received a four-year, $3.2 million NIH grant to develop the PSU Child VAD, a ventricular assist device designed for children ages 1 to 11 who have heart failure. The project aims to fill a critical gap in treatment options, as no long-term heart pumps are currently approved for this age group.
