Rising seas may unlock coastal carbon stores, with losses up to 90%‎

Rising sea levels could do more than flood coastlines. Research from Missouri University of Science and Technology shows they may also trigger the release of large amounts of carbon stored in coastal ecosystems into the atmosphere.

Glowing nanoparticles exposed hidden cancer-protein behavior that could reshape drug screening‎

Using a powerful single-molecule imaging method they developed, a Broad Institute research team has unveiled a dynamic view of how some cancer-related proteins interact in living cells. The technique relies on highly stable nanoparticle probes that brightly illuminate individual molecules for long periods of time. The researchers used their method to observe, for the first time, individual receptors as they move around the cell membrane, attaching to and then letting go of other receptors to alter signaling within the cell.

Necro-branding: Why are deceased celebrities like Michael Jackson still popular when dead?‎

As "Michael," a major biographical film on Michael Jackson, hits cinemas more than a decade and a half after the singer's death, a new study shows that dead artists' brands remain powerful long after they are gone.

Clearing contamination from car interiors‎

Under controlled conditions, Flinders University researchers are investigating third-hand contamination risk from methamphetamine use. Environmental health experts have found open windows and ventilation can reduce but not completely remove methamphetamine contamination on most hard surfaces of a car after an extended period.

Chromatin tracking reveals two motion modes that help control gene expression‎

Gene expression is controlled, in part, by the interactions between genes and regulatory elements located along the genome. Those interactions depend on the ability of chromatin—a mix of DNA and proteins—to move around within a crowded space. In a new study, MIT researchers have measured chromatin movement at timescales ranging from hundreds of microseconds to hours, allowing them to rigorously quantify those dynamics for the first time.

Close-in planets act as 'bouncers' to create rogue worlds‎

Rogue planets sound like rare travelers among the stars, freed from the gravitational constraints of a host system, left to forever wander the interstellar void. But modern models suggest these free floating planets (FFPs) as they are technically known, are actually very common—19 times more common than planets beyond the "snow line," which is the distance from the central star where it becomes cold enough that hydrogen compounds like water, ammonia, and methane can condense into ice.

Live camel transportation improved by using food as an incentive in place of physical punishment‎

Around the world, millions of camels are farmed for milk and meat while others are used in leisure activities like racing and riding. Yet the treatment of these animals as livestock can be harsh, especially during transport. New international research, led by Southern Cross University animal welfare expert Associate Professor Barbara Padalino and published in the journal Animals, shows that more humane camel transportation is possible by using food as an incentive in place of physical punishment.

Arctic winter sea-ice extent fails to expand and sets a new record low in 2026‎

In 2026, the Arctic winter sea-ice extent (annual maximum extent) reached the lowest value since satellite observations began in 1979, following the previous record low in March 2025. As part of the Arctic Challenge for Sustainability III (ArCS III), the National Institute of Polar Research (NIPR) and the Japan Aerospace Exploration Agency (JAXA) maintain a long-term dataset spanning more than 40 years.

Speed 'training' prepares bacteria for complex tasks, like munching plastics‎

Millions of tons of plastic waste accumulate in landfills and oceans every year. One promising response is to engineer microbes to break the plastic down into useful chemical building blocks. However, teaching a bacterium to digest plastic efficiently demands fine-tuning not just one gene, but entire clusters of genes working in concert, like upgrading every machine on a factory assembly line rather than swapping out a single part.

Babies may share adults' sense of beauty, and it appears to sharpen with age‎

Humans tend to be captured by things around them that they perceive as pleasurable and aesthetically pleasing. This "sense of beauty" has been widely studied extensively, mostly in experiments that involved adult participants.
