The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves, using the US National Science Foundation-funded (NSF) LIGO Hanford and Livingston Observatories. The merger produced a final black hole more than 225 times the mass of our Sun. The signal, designated…
Twenty-five years after first warning that oil spills would wane while invasive species and climate impacts would surge, an international team revisits its coastal forecasts and finds many bull’s-eyes, alongside surprising misses. Plastic pollution, ocean acidification, and sensory pollution have risen faster than imagined, even as strong treaties curbed chemicals…
With intensifying global warming and climate change, drought has become a major threat to global agriculture, impacting crop yields and food security. To survive such adverse events, plants have evolved several strategies. One such strategy to counteract water scarcity is ‘stomatal closure,’ where stomata — the tiny pores on leaf…
Every day, your body replaces billions of cells — and yet, your tissues stay perfectly organized. How is that possible? A team of researchers at ChristianaCare’s Helen F. Graham Cancer Center & Research Institute and the University of Delaware believe they’ve found an answer. In a new study published in…
Stroke is said to be the second leading cause of death worldwide after heart disease.

The study, which examined more than 33,000 deaths from obesity-associated cancers, revealed sharp increases in cancer…
Consuming certain sweeteners commonly found in foods and beverages may increase the risk of early puberty in children, particularly among those who are genetically predisposed, according to a study presented at ENDO 2025, the Endocrine Society’s annual meeting in San Francisco, Calif. The researchers found that consuming aspartame, sucralose, glycyrrhizin…
For this ESA/Hubble Picture of the Week, we gaze upon the field of stars that is NGC 1786. This object is a globular cluster in the Large Magellanic Cloud (LMC), a small satellite galaxy of the Milky Way Galaxy that is approximately 160,000 light-years away from Earth. NGC 1786 itself…
A new weekly injectable drug could transform the lives of more than eight million people living with Parkinson’s disease, potentially replacing the need for multiple daily tablets. Scientists from the University of South Australia (UniSA) have developed a long-acting injectable formulation that delivers a steady dose of levodopa and carbidopa…
While humans can regularly replace certain cells, like those in our blood and gut, we cannot naturally regrow most other parts of the body. For example, when the tiny sensory hair cells in our inner ears are damaged, the result is often permanent hearing loss, deafness, or balance problems. In…
Astronomers have detected a giant exoplanet – between three and ten times the size of Jupiter – hiding in the swirling disc of gas and dust surrounding a young star. Earlier observations of this star, called MP Mus, suggested that it was all alone without any planets in orbit around…
Researchers have demonstrated a new technique that allows “self-driving laboratories” to collect at least 10 times more data than previous techniques at record speed. The advance – which is published in Nature Chemical Engineering – dramatically expedites materials discovery research, while slashing costs and environmental impact. Self-driving laboratories are robotic…
The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves using the US National Science Foundation (NSF)-funded LIGO observatories.
