“Magic sand” might help us understand the physics of granular matter

(Tokyo Metropolitan University) Tokyo, Japan – Researchers from Tokyo Metropolitan University have studied the properties of mixtures of silicone-coated “magic sand”, a popular kid’s toy, and normal sand. Silicone-coated sand particles were found to interact with each other only, and not with other sand particles. The team discovered that adding silicone-coated sand beyond a certain threshold leads to an abrupt change in clustering and rigidity, a simple, useful way to potentially tune the flow of granular materials for industry.

Astronomers spy a nearby, blazing hot super-Earth

Most exoplanets orbiting close to their stars don’t have atmospheres. But Gliese 486b – orbiting a red dwarf star only 24 light-years away – does. It’s close enough to see well. Astronomers will be watching it!

Woolly mammoths may have shared the landscape with first humans in New England

(Dartmouth College) Woolly mammoths may have walked the landscape at the same time as the earliest humans in what is now New England, according to a Dartmouth study published in Boreas. Through the radiocarbon dating of a rib fragment from the Mount Holly mammoth from Mount Holly, Vt., the researchers learned that this mammoth existed approximately 12,800 years ago. This date may overlap with the arrival of the first humans in the Northeast, who are thought to have arrived around the same time.

NASA’s ICESat-2 satellite reveals shape, depth of Antarctic ice shelf fractures

(Penn State) When a block of ice the size of Houston, Texas, broke off from East Antarctica’s Amery Ice Shelf in 2019, scientists had anticipated the calving event, but not exactly where it would happen. Now, satellite data can help scientists measure the depth and shape of ice shelf fractures to better predict when and where calving events will occur, according to researchers.

Gulf Stream at its weakest in over 1,000 years

A new study suggests that the Gulf Stream – an Atlantic Ocean current that plays a large role in shaping Earth’s weather patterns – is weaker now than at any point in the last 1,000 years.

NASA scientists complete 1st global survey of freshwater fluctuation

(NASA/Goddard Space Flight Center) To investigate humans’ impact on freshwater resources, scientists have now conducted the first global accounting of fluctuating water levels in Earth’s lakes and reservoirs — including ones previously too small to measure from space.

NASA selects 16 futuristic space technology concepts

NASA has selected 16 cool new futuristic space technology concepts for further study. Four of them are from NASA’s own Jet Propulsion Laboratory (JPL), including a railway system on the moon to move cargo.

Assessing the aggregate and spatial economic impact of global warming | VOX, CEPR Policy Portal –

The effects of climate change are heterogenous across space. While some regions will be significantly negatively impacted, others may benefit from warmer temperatures. This column uses an integrated assessment model with rich spatial data that looks at interactions between regions…

NASA ERB Satellite Measurements Don’t Support Global Warming Claims

NASA Earth Radiation Budget (ERB) measurements from satellite data don’t support global warming claims. Analyst blogger Zoe Phin downloaded and analyzed 10 gigabytes of NASA instrumental data on the earth’s radiation budget (ERB) fully covering the years 2003 to 2019…
