Shark-bitten orcas in the Northeastern Pacific could be a new population of killer whale      (via sciencedaily.com)     Original source 

Researchers believe a group of killer whales observed hunting marine mammals including sperm whales, as well as a sea turtle, in the open ocean off California and Oregon could be a new population. Based on available evidence, the researchers posit that the 49 orcas could belong to a subpopulation of transient killer whales or a unique oceanic population found in waters off the coast of California and Oregon.

Tropical birds could tolerate warming better than expected, study suggests      (via sciencedaily.com)     Original source 

We expect tropical animals to handle a certain degree of heat, but not wild swings in temperature. That seems to be true for tropical ectotherms, or 'cold-blooded' animals such as amphibians, reptiles, and insects. However, in a new study of 'warm-blooded' endotherms, a research team found tropical birds can handle thermal variation just fine.

Molecular simulations of ammonia mixtures support search for renewable fuels      (via sciencedaily.com)     Original source 

Ammonia is an important molecule with many applications. The end product of the famed Haber-Bosch process, it is commonly synthesized to capture nitrogen for fertilizers, and is used for refrigeration, in cleaning products, and in the production of pharmaceuticals. Recently, this modest molecule has also attracted interest as a potential resource for addressing one of today's most pressing challenges -- the need for reliable and abundant renewable fuels.

Exploring arctic plants and lichens: An important conservation baseline for Nunavut's newest and largest territorial park      (via sciencedaily.com)     Original source 

A comprehensive study of the floristic diversity of Agguttinni Territorial Park, Nunavut's newest and largest Territorial Park, has documented 141 vascular plant, 69 bryophyte, and 93 lichen species from this unique protected area on northern Baffin Island. Through a combination of extensive fieldwork in 2021 and examination of hundreds of existing herbarium specimens, the authors have documented species newly reported for Baffin Island and have crafted a biodiversity baseline important for park management and conservation.

Spiral wrappers switch nanotubes from conductors to semiconductors and back      (via sciencedaily.com)     Original source 

By wrapping a carbon nanotube with a ribbon-like polymer, researchers were able to create nanotubes that conduct electricity when struck with low-energy light that our eyes cannot see. In the future, the approach could make it possible to optimize semiconductors for applications ranging from night vision to new forms of computing.

Preventing magnet meltdowns before they can start      (via sciencedaily.com)     Original source 

High-temperature superconductor magnets have the potential to lower the costs of operating particle accelerators and enable powerful new technologies like fusion reactors. But quenches -- the sudden, destructive events wherein a part of the material loses superconductivity -- are a major barrier to their deployment. Scientists have developed an approach to prevent quenches altogether, rather than simply trying to manage them after they occur.

Herbivores, displaced by ocean warming, threaten subtropical seagrass meadows      (via sciencedaily.com)     Original source 

The findings suggest that subtropical seagrasses are less resilient to heavy grazing from marine herbivores, in part because they receive less sunlight relative to their tropical counterparts. As tropical herbivores move into subtropical waters, overgrazing may prevent subtropical seagrass meadows from persisting in these environments.
