NASA Measures Interior of Mars for the First time, Revealing Huge Liquid Core

In the first ever measurement of another planet’s core, seismography conducted over several Martian years have revealed the liquid metal core is softer than expected—more like a Mars-mellow than a Mars Bar. While the recently arrived Perseverance rover has been hoovering up much of the Mars-related attention, a trio of recently published papers that measured […]

Ten Unusual Places Where Researchers Have Found Microplastics

Any plastic piece that’s less than five millimeters in length is known as microplastic. To better understand how tiny these pieces are, a grain of rice is a little larger. It’s about the size of a pencil eraser.Microplastics come from plastic that’s not recycled and breaks down. Small fragments chip or flake off as the […]

Review evaluates the evidence for an intensifying Indian Ocean water cycle

(Woods Hole Oceanographic Institution) The Indian Ocean has been warming much more than other ocean basins over the last 50-60 years. While temperature changes basin-wide can be unequivocally attributed to human-induced climate change, it is difficult to assess whether contemporary heat and freshwater changes in the Indian Ocean since 1980 represent an anthropogenically-forced transformation of the hydrological cycle. What complicates the assessment is factoring in natural variations, regional-scale trends, a short observational record, climate model uncertainties, and the ocean basin’s complex circulation.

Unusual currents explain mysterious red crab strandings

(University of California – Santa Cruz) Researchers studied pelagic red crab range and strandings from 1950 to 2019 and compared these data with ocean conditions, like temperature and current movements. The team found that the appearance of red crabs outside of their normal range correlated with the amount of seawater flowing from Baja California to central California.

Earth’s cryosphere shrinking by 87,000 square kilometers per year

(American Geophysical Union) A new study in AGU’s journal Earth’s Future reports the first global assessment of the extent of snow and ice cover on Earth’s surface–a critical factor cooling the planet through reflected sunlight–and its response to warming temperatures.

The Northwest heat wave is ‘unprecedented.’ Here’s what’s pushing it into uncharted territory. – CNN

CNN —   As temperatures surged past 100 degrees, Bree Oswill gathered all the blankets and towels she could find and taped them to every window that didn’t have a shade. She doesn’t have central air conditioning and wanted to…

FSU researchers find most nitrogen in Gulf of Mexico comes from coastal waters

(Florida State University) Almost all of the nitrogen that fertilizes life in the open ocean of the Gulf of Mexico is carried into the gulf from shallower coastal areas, researchers from Florida State University found.

Emissions cause delay in rainfall

(DOE/Pacific Northwest National Laboratory) Rising greenhouse gases and declining aerosols have triggered an approximate four-day delay in rainfall over tropical land and the Sahel.
