A recent reanalysis of the outsize black hole galaxy UHZ1 using existing X-ray data and new infrared observations challenges a previous groundbreaking claim. Three years ago, this galaxy made news for hosting an unusually massive and heavily dust-obscured black hole formed throug
A surprising discovery from Rockefeller University suggests that a common amino acid could play a powerful role in protecting against cancer and viral infections. Scientists found that low arginine levels interfere with the immune system's ability to recognize dangerous cells, wh
On April 10, 2019, the Event Horizon Telescope (EHT) Collaboration revealed the first picture of a black hole. The object is at the center of a galaxy known as M87, about 55 million light-years away.
In propulsion system design, engineers have long faced a trade-off between solid and liquid rocket fuels. Each has advantages and disadvantages, and in an effort to try to min/max the efficacy of different types of fuel, researchers have long placed an emphasis on a hybrid betwee
5,000-year-old skulls reveal a disturbing secret of ancient Egypt's first kings and more — today's student signal.
A 5,000-year-old mystery surrounding the tombs of Egypt’s first kings has taken a disturbing turn. Scientists reexamining 46 ancient skulls discovered evidence of potentially fatal head injuries in 18, suggesting that at least 39% of those studied may have been deliberately kille
Extra time on assignments. Frequent breaks. A quiet place to work. For students with attention-deficit/hyperactivity disorder (ADHD), these are some of the most common accommodations schools provide to make learning easier. But are they actually helping children succeed? A new st
A technology that significantly improves ethanol gas sensing performance by combining five different metal elements in a single oxide has been developed.
A study in the International Journal of Innovation and Sustainable Development of teachers' behavior during outdoor play at kindergarten has identified a gap between the support children need and the help educators provide, particularly in emotional and social development.
A star's explosive demise has added a shiny new feature to NGC 1433, a barred spiral galaxy approximately 50 million light-years away in the southern constellation Horologium (the Pendulum Clock). New images of supernova SN 2026ahvu from the U.S. Department of Energy–fabricated D
While young people are constantly exposed to news about climate change, their resulting anxiety does not always translate into environmental action. A new study published in Climate reveals that the relationship between climate distress and climate action is highly complex. While
The ESA's Euclid has already teased us with some early results. In the past, it's given us a small image covering 60 square degrees of the sky, created with a few days of observations. Those images showed individual targets from the Horsehead Nebula to the Perseus cluster of gala
Megafauna remains, stone tools and rare plant material recovered from the 125,000-year-old lakeside site of Uruq al-Julaybah in Mundafan, southern Saudi Arabia, provide one of the most detailed pictures yet of prehistoric human life in Arabia. Together, the discoveries reveal how
UBC researchers have helped uncover 15,000 new potential strong gravitational lenses—the largest collection of these cosmic tools that help astronomers investigate dark matter.
Tsunamis triggered by volcanic eruptions are poorly understood because of the complex dynamics governing how falling rocks and ash interact with seawater to generate waves. As a result, it is difficult to anticipate whether a volcanic flow will trigger a tsunami and, if so, how b
When a cloud of atoms is cooled close to absolute zero, its atoms can merge into a Bose–Einstein condensate (BEC): an exotic fluid in which atoms across the whole cloud share a single quantum state. Current theories predict that as a disordered quantum gas settles into this order
Global temperatures may continue to rise even after human CO₂ emissions stop. The temperature change that follows is known as the zero emissions commitment (ZEC), and it is often assumed to be close to zero. A study led by the Met Office Hadley Center, with co-authors from severa
An international team of paleontologists, including researchers from McGill University, has discovered "remarkably large" rodent fossils in the pit of a mine in southern Thailand. The finding, published in Scientific Reports, provides a new perspective on the early manifestation
Scientists have discovered that vitamin C may help prevent potentially cancer-causing chemicals from forming in the stomach after eating foods containing nitrates and nitrites. A new mathematical model suggests that taking vitamin C after meals could reduce these harmful reaction
Scientists have uncovered a surprising genetic connection to spinal degeneration and found that an existing osteoporosis drug can prevent damaging mineral buildup in zebrafish spines. The discovery could pave the way for new treatments that slow or prevent a major cause of chroni
A recent reanalysis of the outsize black hole galaxy UHZ1 using existing X-ray data and new infrared observations challenges a previous groundbreaking claim. Three years ago, this galaxy made news for hosting an unusually massive and heavily dust-obscured black hole formed throug
The strange, wildly tilted magnetic fields of Uranus and Neptune have puzzled scientists since NASA's Voyager 2 spacecraft explored the planets in the 1980s. New simulations suggest that extreme conditions deep inside these icy giants create unusual electrical properties that cou
Indigenous farmer Banu Ismahasan walks through a golden field of tall stalks in southeastern Taiwan, harvesting by hand the grain heads of an ancient crop resistant to extreme weather.
For a decade, the 1.5C goal has served as the north star of climate action, a line nations pledged to hold to avoid the worst ravages of a warming planet.
