Newly discovered form of salty ice could exist on surface of extraterrestrial moons
Scientists suspect that the red streaks crossing the surface of Jupiter’s moon Europa is a frozen mixture of water and salts, but its chemical signature matches no known substance on Earth. Now researchers have discovered a new type of solid crystal that forms when water and table salt combine in cold, pressurized conditions. Researchers believe the new substance created in a lab on Earth could form at the surface and bottom of these worlds’ deep oceans.

Ice cores show even dormant volcanoes leak abundant sulfur into the atmosphere
Non-erupting volcanoes leak a surprisingly high amount of sulfur-containing gases. A Greenland ice core shows that volcanoes quietly release at least three times as much sulfur into the Arctic atmosphere than estimated by current climate models. Aerosols are the most uncertain aspect of current climate models, so better estimates could improve the accuracy of long-term projections.

Warming oceans have decimated marine parasites — but that’s not a good thing
Save the … parasites? Analyzing 140 years of parasite abundance in fish shows dramatic declines, especially in parasites that rely on three or more host species. The decline is linked to warming ocean temperatures. Parasitic species might be in real danger, researchers warn — and that means not just fewer worms, but losses for the entire ecosystem.

Study reveals how ancient fish colonized the deep sea
A new University of Washington-led study reports that throughout Earth’s ancient history, there were several periods of time when many fish actually favored the cold, dark, barren waters of the deep sea instead of shallow ocean waters that are warm and full of resources.
Permanent daylight saving time would reduce deer-vehicle collisions, study shows
University of Washington researchers found that adopting permanent daylight saving time in the United States would reduce deer-vehicle collisions and likely prevent an estimated 36,550 deer deaths, 33 human deaths, 2,054 human injuries and $1.19 billion in costs each year. Deer-vehicle collisions would decrease under permanent DST because skies would be brighter later into the evening.

Study suggests La Niña winters could keep on coming
Forecasters are predicting a “three-peat La Niña” this year. This will be the third winter in a row that the Pacific Ocean has been in a La Niña cycle, something that’s happened only twice before in records going back to 1950. A new study of temperature patterns in the tropical Pacific Ocean suggests that climate change is, in the short term, favoring La Niñas.

Deepest scientific ocean drilling effort sheds light on Japan’s next ‘big one’
A 2018 expedition that drilled farther into the seafloor than ever before — almost 2 miles — sought to take measurements of stress as close as possible to a tectonic fault off the coast of Japan. Surprisingly, the researchers found little built-up tectonic stress. The findings could help to better understand earthquakes in subduction zones around the world.

‘Dangerous’ and ‘extremely dangerous’ heat stress to become more common by 2100
A new study projects the number of days with “dangerous” and “extremely dangerous” mixtures of heat and humidity by the end of this century. Even if global warming is limited to 2 degrees Celsius, results show that deadly heat waves will become much more common in the mid-latitudes, and many tropical regions will experience “dangerous” heat for about half the year.

New study calculates retreat of glacier edges in Alaska’s Kenai Fjords National Park
As glaciers worldwide retreat due to climate change, managers of national parks need to know what’s on the horizon to prepare for the future. A new study from the University of Washington and the National Park Service measures 38 years of change for glaciers in Kenai Fjords National Park south of Anchorage. The study, published Aug. 5 in The Journal of Glaciology, finds that 13 of the 19 glaciers show substantial retreat, four are relatively stable, and two have advanced. It also finds trends in which glacier types are disappearing fastest.

‘Safety in numbers’ tactic keeps Pacific salmon safe from predators
A new University of Washington study that leverages historical data has found unique support for a “safety in numbers” hypothesis by showing that Pacific salmon in larger groups have lower risk of being eaten by predators. But for some salmon species, schooling comes at the cost of competition for food, and those fish may trade safety for a meal.

Solar energy explains fast yearly retreat of Antarctica’s sea ice
Sea ice around Antarctica retreats more quickly than it advances, an asymmetry that has been a puzzle. New analysis shows that the Southern Hemisphere is following simple rules of physics, as peak midsummer sun causes rapid changes. In this respect, it seems, it’s Arctic sea ice that is more mysterious.
