A Swedish-led research team at Karolinska Institutet and Karolinska University Hospital has shown in a new randomized clinical trial that a low dose of the well-known medicine aspirin halves the risk of recurrence after surgery in patients with colon and rectal cancer with a certain type of genetic alteration in...
Clam Shells Sound Warning of Atlantic ‘Tipping Point’
A study of clam shells suggests Atlantic Ocean currents may be approaching a “tipping point”.
Research Finds Crop Breeding Can Cut Methane Emissions Without Sacrificing Yield
Genetic selection could help farmers and breeders reduce greenhouse gases from crops, particularly rice cultivation, research by the University of Warwick and Cranfield University shows.
Cooler Warm Periods: How the Southern Ocean Controlled Climate and Atmospheric CO2
The Southern Ocean around Antarctica plays a decisive role in the global carbon cycle – and thus in the climate system.
Phytoplankton – The Tiny Climate Heroes of the Ocean
They are microscopic, yet they play a gigantic role in the climate system: the tiny microalgae collectively known as phytoplankton.
3,000 years of secrets hidden beneath Egypt’s greatest temple
A sweeping new geoarchaeological study has revealed how Egypt’s famed Karnak Temple complex rose from an island amid Nile floods to become one of the ancient world’s most enduring sacred centers. By analyzing sediments and pottery fragments, researchers traced its transformation across three millennia and uncovered evidence that its placement...
It’s not just genes — parents can pass down longevity another way
Scientists studying tiny roundworms have uncovered how the secrets of a long life can be passed from parents to their offspring — without changing DNA. The discovery shows that when certain cellular structures called lysosomes change in ways that promote longevity, those benefits can travel from body cells to reproductive...
From gentle giants to ghostly hunters, sharks face an unseen peril
New research reveals that deep-sea mining could dramatically threaten 30 species of sharks, rays, and ghost sharks whose habitats overlap with proposed mining zones. Many of these species, already at risk of extinction, could face increased dangers from seafloor disruptions and sediment plumes caused by mining activity.
These little robots literally walk on water
HydroSpread, a breakthrough fabrication method, lets scientists build ultrathin soft robots directly on water. These tiny, insect-inspired machines could transform robotics, healthcare, and environmental monitoring.
What looks like dancing is actually a bug’s survival trick
The matador bug’s flamboyant leg-waving puzzled scientists for years, with early guesses pointing to courtship. But experiments revealed the waving is a defense tactic against predators. Related species also share the behavior, possibly signaling toxicity or creating visual confusion. The discovery raises fresh questions about insect evolution and survival strategies.
