Here"s how NASA is planning to protect Earth from asteroids and comets
The large impact craters dotting our planet are powerful reminders that asteroids and comets strike the Earth from time to time. As often said, it's not a question of "if"; it's a matter of "when" our planet will face an impending strike from space......»»
Explaining dramatic planetwide changes after world"s last "Snowball Earth" event
Some of the most dramatic climatic events in our planet's history are "Snowball Earth" events that happened hundreds of millions of years ago, when almost the entire planet was encased in ice up to 0.6 miles (1 kilometer) thick......»»
Could interstellar quantum communications involve Earth or solve the Fermi paradox?
Thus far, the search for extraterrestrial intelligence (SETI) has used strategies based on classical science—listening for radio waves, telescopes watching for optical signals, telescopes in orbit scouring light from the atmospheres of exoplanets,.....»»
Differential privacy in AI: A solution creating more problems for developers?
In the push for secure AI models, many organizations have turned to differential privacy. But is the very tool meant to protect user data holding back innovation? Developers face a tough choice: balance data privacy or prioritize precise results. Dif.....»»
New research re-envisions Earth"s mantle as a relatively uniform reservoir
Lavas from hotspots—whether erupting in Hawaii, Samoa or Iceland—likely originate from a worldwide, uniform reservoir in Earth's mantle, according to an evaluation of volcanic hotspots published in Nature Geoscience......»»
Neutron scientists wake a sleeping giant after nine-month nap and makeover
What's the best way to wake a giant after a long nap? "Very carefully, and with a lot of planning," said a grinning John Galambos. He was the project director for the Proton Power Upgrade project, or PPU, at Oak Ridge National Laboratory until his re.....»»

Geoscientists confirm "dripping" of Earth"s crust beneath Türkiye"s Central Anatolian Plateau
Recent satellite data reveal that the Konya Basin in the Central Anatolian Plateau of Türkiye is continually being reshaped over millions of years, according to a new analysis led by Earth scientists at the University of Toronto......»»
Could you find what a lunar crater is made of by shooting it?
Americans are famously fond of their guns. So it should come as no surprise that a team of NASA scientists has devised a way to "shoot" a modified type of sensor into the soil of an otherworldly body and determine what it is made out of. That is prec.....»»
Materials scientist describes new world order for glasses, liquids
In 1543, Copernicus pitched the heliocentric idea that the Earth orbited the sun. His theory took 150 years to catch on and more than 400 years for the Vatican to officially accept it. Likewise, distinguished materials scientist Takeshi Egami has spe.....»»
How scientists are keeping the Orion spacecraft safe from radiation
NASA's Orion spacecraft will need to protect astronauts from dangerous radiation when they visit the moon in the upcoming Artemis missions......»»
Reinventing the clock: NASA"s new tech for space timekeeping
Here on Earth, it might not matter if your wristwatch runs a few seconds slow. But crucial spacecraft functions need accuracy down to one billionth of a second or less. Navigating with GPS, for example, relies on precise timing signals from satellite.....»»
Measuring moon dust to fight air pollution
Moon dust, or regolith, isn't like the particles on Earth that collect on bookshelves or tabletops—it's abrasive and it clings to everything. Throughout NASA's Apollo missions to the moon, regolith posed a challenge to astronauts and valuable space.....»»
Work is underway on NASA"s next-generation asteroid hunter
The mirrors for NASA's Near-Earth Object Surveyor space telescope are being installed and aligned, and work on other spacecraft components is accelerating......»»
More governments are promising a "right to disconnect"—but psychology affects how well we can unplug from work
The idea of a "right to disconnect" from work is gaining traction worldwide, with countries like France and Spain enacting laws to protect workers from the demands of the digital age. The UK government has also indicated it will do the same......»»
