Whale poop contains iron that may have helped fertilize past oceans
A recent theory proposes that whales weren’t just predators in the ocean environment: Nutrients that whales excreted may have provided a key fertilizer to these marine ecosystems. Research led by University of Washington oceanographers finds that whale excrement contains significant amounts of iron, a vital element that is often scarce in ocean ecosystems, and nontoxic forms of copper, another essential nutrient that in some forms can harm life.

Grasshopper size changes suggest how to predict winners and losers under climate change
Thousands of grasshopper specimens from mountains in Colorado show trends in how the insects changed in size over 65 years. With earlier emergence of spring greenery and earlier summer drought, grasshopper species that emerged early in the year grew larger, while grasshopper species that emerge later in the year grew smaller in size. The study, led by UW biologist Lauren Buckley, shows that changes in insect size can be predicted based on lifecycles and environmental conditions.
Q&A: UW researchers are designing cancer therapeutics that can kill cancer cells and restore healthy tissue

Q&A: How rate of CO2 rise can affect a global ocean current
How fast the level of atmospheric carbon dioxide — and with it, the temperature — goes up matters for the ability of humans and ecosystems to adjust. A slower increase gives humans time to move away from low-lying coasts and animals time to move to new habitats. It turns out the rate of that increase matters for non-living systems, too. Camille Hankel, a postdoctoral researcher at the Cooperative Institute for Climate, Ocean and Ecosystem Studies, talks about her research on the Atlantic Ocean circulation.

The carbon in our bodies probably left the galaxy and came back on cosmic ‘conveyor belt’
University of Washington scientists recently discovered that the giant ‘conveyor belt’ currents that push star-forged material out of our galaxy and pull it back in can also transport carbon atoms. That means that a good deal of the carbon here on Earth, including the carbon in our bodies, likely left the galaxy at some point!

Surveys show full scale of massive die-off of common murres following the ‘warm blob’ in the Pacific Ocean
Colony surveys of common murres, an Alaskan seabird, show the full effects of the 2014-16 marine heat wave known as “the blob.” Analysis of 13 colonies surveyed between 2008 and 2022 finds that colony size in the Gulf of Alaska dropped by half after the marine heat wave. In colonies along the eastern Bering Sea, west of the peninsula, the decline was even steeper, at 75% loss. No recovery has yet been seen.

More than 10,000 supernovae counted in stellar census
Since 2018 the Zwicky Transient Facility, an international astronomical collaboration based at the Palomar Observatory in California, has scanned the entire sky every two to three nights. As part of this mission, the ZTF’s Bright Transient Survey has been counting and cataloguing supernovae — flashes of light in the sky that are the telltale signs of stars dying in spectacular explosions. On Dec. 4, ZTF researchers — including astronomers at the University of Washington — announced that that they have identified more than 10,000 of these stellar events, the largest number ever identified by an astronomical survey.
Record-low Antarctic sea ice can be explained and forecast months out by patterns in winds
University of Washington researchers show that the all-time record low in winter sea ice extent in 2023 can be explained by warm Southern Ocean conditions and patterns in the winds that circled Antarctica months earlier, allowing forecasts for sea ice coverage around the South Pole to be generated six or more months in advance. This could support regional and global weather and climate models.

That’s no straw: Hummingbirds evolved surprisingly flexible bills to help them drink nectar
Hummingbird bills — their long, thin beaks — look a little like drinking straws. But new research shows just how little water, or nectar, that comparison holds. University of Washington scientists have discovered that the hummingbird bill is surprisingly flexible. While drinking, a hummingbird rapidly opens and shuts different parts of its bill simultaneously, engaging in an intricate and highly coordinated dance with its tongue to draw up nectar at lightning speeds.

Fewer than 7% of global hotspots for whale-ship collisions have protection measures in place
A new study led by the University of Washington has for the first time quantified the risk for whale-ship collisions worldwide for four geographically widespread ocean giants that are threatened by shipping: blue, fin, humpback and sperm whales. In a paper published online Nov. 21 in Science, researchers report that global shipping traffic overlaps with about 92% of these whale species’ ranges. Only about 7% of areas at highest risk for whale-ship collisions have any measures in place to protect whales from this threat. These measures include speed reductions, both mandatory and voluntary, for ships crossing waters that overlap with whale migration or feeding areas.
