Umbrella for atoms: The first protective layer for 2D quantum materials      (via sciencedaily.com)     Original source 

As silicon-based computer chips approach their physical limitations in the quest for faster and smaller designs, the search for alternative materials that remain functional at atomic scales is one of science's biggest challenges. In a groundbreaking development, researchers have engineered a protective film that shields quantum semiconductor layers just one atom thick from environmental influences without compromising their revolutionary quantum properties. This puts the application of these delicate atomic layers in ultrathin electronic components within realistic reach.

The Golgi organelle's ribbon structure is not exclusive to vertebrates, contrary to previous consensus      (via sciencedaily.com)     Original source 

Researchers report that the Golgi ribbon, an organelle structure previously thought to be exclusive to vertebrates, is also present in animal taxa, including mollusks, earthworms, and sea urchins. The function of the Golgi ribbon is still enigmatic, but its presence in diverse animal lineages indicates that its function is not vertebrate specific, as previously thought. The team also showed Golgi ribbons form at a specific timepoint during embryogenesis, which suggests that they might play a role in cell differentiation.

Climate change shrinking fish      (via sciencedaily.com)     Original source 

Fish weight in the western North Pacific Ocean dipped in the 2010s due to warmer water limiting food supplies, according to a new study. Researchers analyzed the individual weight and overall biomass of 13 species of fish. In the 1980s and 2010s, the fish were lighter. They attributed the first period of weight loss to greater numbers of Japanese sardine, which increased competition with other species for food. During the 2010s, while the number of Japanese sardine and chub mackerel moderately increased, the effect of climate change warming the ocean appears to have resulted in more competition for food, as cooler, nutrient-dense water could not easily rise to the surface. These results have implications for fisheries and policymakers trying to manage ocean resources under future climate change scenarios.

Walleye struggle with changes to timing of spring thaw      (via sciencedaily.com)     Original source 

Walleye are one of the most sought-after species in freshwater sportfishing, a delicacy on Midwestern menus and a critically important part of the culture of many Indigenous communities. They are also struggling to survive in the warming waters of the Midwestern United States and Canada. According to a new study, part of the problem is that walleye are creatures of habit, and the seasons -- especially winter -- are changing so fast that this iconic species of freshwater fish can't keep up.

Climate change could push bowhead whales to cross paths with shipping traffic      (via sciencedaily.com)     Original source 

The population of bowhead whales that migrates between the Bering and Beaufort Seas each year is a conservation success story, with today's population nearing -- if not exceeding -- pre-commercial whaling numbers. But climate change is shifting the whales' feeding grounds and migration patterns, potentially pushing them to spend more time in the paths of oncoming ships, according to a new study.
