Swordfish spend much of their time hunting prey about 600 meters (1,970 feet) below the surface in the ocean twilight zone, but occasionally, they reach depths of more than 1,000 meters (3,280 feet). Now, scientists from the Woods Hole Oceanographic Institution (WHOI) are investigating what may be behind these extreme dives.

An international team of researchers, led by Jonathan Freundlich (University of Strasbourg, Astronomical Observatory), has revealed how a dense cosmic environment depletes galaxies of their gas. By mapping the molecular gas in a galaxy group located 7 billion light-years away, they found that the galaxies in this group harbor, on average, gas reservoirs reduced by more than half compared to similar isolated galaxies. The results of this study are published in the journal Astronomy & Astrophysics.
Researchers have analyzed water samples collected during two expeditions aboard the research icebreaker Polarstern to investigate how life and changing conditions on the Antarctic continental shelf affect carbon carried into the deep ocean. Published in Nature Communications, the study reveals a surprising finding: Despite intense biological activity and major changes in the water masses, the amount and make-up of dissolved organic matter remain almost unchanged.
Shoppers often greet the closure of a Walmart with dismay, while competitors find cause to celebrate.
Researchers at the U.S. Department of Energy’s (DOE) Ames National Laboratory have discovered a way to control the handedness of magnons, tiny magnetic waves that can carry information through materials. By changing the material’s magnetic state with an external magnetic field, they were able to switch magnon behavior, a finding with potential applications in quantum information and quantum computing technologies. Their findings are published in Physical Review Letters.
An international collaboration demonstrates that classical nonlinear dynamics can drive single- and two-photon states to thermalize, opening new avenues for simulating complex quantum many-body systems within accessible optical architectures.
A permanent lunar base will require structures resilient enough to withstand everything from cosmic radiation and micro-meteorites to moonquakes. There are plenty of building materials to choose from on Earth, but they all come with a catch: transportation storage aboard spacecraft is limited, and each additional pound of cargo will quickly ramp up costs. Engineers have spent years experimenting with ways for future astronauts to source local lunar ingredients, including fine moon dust known as regolith. Unfortunately, most require various binding ingredients that must still be sent from back home. A college student at the University of Arkansas (U of…
OpenAI has not yet said what its plans are for the future of travel. But Sonder founder Francis Davidson is a well-known figure in the travel industry.
Researchers from King’s College London and Rutgers University in New Jersey created a modified enzyme (a protein that speeds up chemical reactions) that breaks down polyethylene terephthalate (PET) plastic 10 times quicker, using 10 times less enzyme. They accomplished this just by changing the liquid it works in and making small changes to the enzyme’s structure.
A review published in the International Journal of Managerial and Financial Accounting on the subject of greenwashing in financial services has found that financial institutions often claim environmental responsibility while continuing to finance high-carbon projects.
