Polymer physics reveals DNA loops are formed by single molecular motors‎

Scientists from Skoltech and the University of Potsdam have developed a physical theory that sheds light on how molecular motors organize the three-dimensional structure of the genome. Using theoretical polymer physics and computer simulations, the researchers for the first time calculated a universal parameter of this organization—the density of loops formed through active extrusion by cohesin motors in each living cell.

How industry and geography play a role in support for radical right parties‎

Dr. Ruben Ruiz Rufino found that communities with clusters of workers in labor-intensive sectors consistently showed higher levels of support for radical-right movements than areas dominated by knowledge-based industries. The study, published in the journal Political Studies, sought to examine how local economic environments shape political attitudes across Europe.

Titan's lakes may spawn 10-foot waves in gentle winds, new model suggests‎

On a calm day, a light breeze might barely ripple the surface of a lake on Earth. But on Saturn's largest moon, Titan, a similar mild wind would kick up 10-foot-tall waves. This otherworldly behavior is one prediction from a new wave model developed by scientists at MIT. The model is the first to capture the full dynamics of waves and what it takes to whip them up under different planetary conditions.

Tracing anglers in the Gulf Coast: New machine learning tools reveal when, where and how anglers fish‎

The Gulf Coast is recognized worldwide for its exceptional fishing opportunities, offering anglers a wide variety of species such as trout, red snapper, and grouper. Recreational fishing represents a significant—yet historically undermeasured—aspect of overall fisheries pressure in the region, raising concerns about its impact on fish populations and the need for effective conservation and management.

Waikīkī faces escalating threat of sewage-contaminated flooding as sea level rises‎

A new study by University of Hawai'i at Mānoa researchers revealed that Waikīkī is facing a fundamental shift in flood hazards as sea levels rise—transitioning from a flooding that is driven primarily by rainfall to events increasingly dominated by tidal processes.

ALMA confirms rare quasar pair at redshift 5.7 in merging galaxies‎

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have discovered a close pair of quasars, which is a result of a distant massive galaxy merger. The detection of the quasar pair was detailed in a research paper published April 7 on the arXiv pre-print server.

Combining seismic and space data to detect calving in Greenland glaciers‎

When the edge of a Greenland glacier breaks off into the sea to become an iceberg, can a global seismic network "hear" it? The answer is yes—but only if the event is a large one. And it helps to pair the resulting surface seismic waves with satellite observations to get the best overall chance at detecting calving tidewater glaciers, researchers said at the 2026 SSA Annual Meeting.

AI turns plain-language prompts into lab-ready recipes for novel materials‎

Advances in artificial intelligence promise to help chemical engineers discover complex new materials. These materials could be used for reactions such as turning carbon dioxide into fuel, but technical barriers have limited catalysis adoption so far. Researchers at the University of Rochester are now harnessing the benefits of large language models (LLMs) similar to ChatGPT, Claude, or Gemini to empower more researchers to use AI to discover new materials and accelerate experiment workflows.

Ancient viruses serve as gene delivery couriers to help bacteria resist antibiotics‎

Research has shed important new light on the enemies-turned-allies that allow bacteria to exchange genes, including those linked to antimicrobial resistance (AMR). The insights, which expand our understanding of the major global health threat of AMR, came as John Innes Center researchers investigated the curious phenomena of gene transfer agents (GTAs).

Cells have a secret 'courier system' that could open hard-to-reach targets for RNA and gene therapies‎

Researchers at University College Dublin have discovered a previously unknown "courier system" that cells use to deliver coherent biological messages between each other, opening new possibilities for medicine and biotechnology. These courier systems also possess "keys" to natural (endogenous) gateways, allowing them to reach biological locations that are currently inaccessible in conventional delivery medicine.
