Researchers at MIT have tested a new technology for turning water vapor in the atmosphere into drinkable water, even in extreme environments.

Rolling for science: Mars orbiter learns new moves after nearly 20 years in space
After nearly 20 years of operations, NASA’s Mars Reconnaissance Orbiter (MRO) is on a roll, performing a new maneuver to squeeze even more science out of the busy spacecraft as it circles the Red Planet. Engineers have essentially taught the probe to roll over so that it’s nearly upside down. Doing so enables MRO to look deeper underground as it searches for liquid and frozen water, among other things.
The new capability is detailed in a paper recently published in The Planetary Science Journal documenting three “very large rolls,” as the mission calls them, that were performed between 2023 and 2024.
“Not only can you teach an old spacecraft new tricks, you can open up entirely new regions of the subsurface to explore by doing so,” said one of the paper’s authors, Gareth Morgan of the Planetary Science Institute in Tucson, Arizona.
Amazon Is Building a Gigantic Computing Facility to Match the Human Brain
Indiana’s newest cash crop isn’t soybeans or corn; it’s AI data centers — lots and lots of AI data centers.
The New York Times reports that Amazon is building a vast complex of AI infrastructure facilities on top of 1,200 acres of former cropland, all meant for startup Anthropic’s project to build an AI model that is as powerful, complex — and, just possibly, as intelligent — as the human brain.
To that end, Amazon has constructed seven data centers on site, with around 30 slated to be built in total, according to the newspaper. It’s such an outrageously ambitious project, with untold billions in investment, that Amazon has tapped four separate construction firms to get the complex finished as soon as possible.
Saturday Citations: Upside-down sharks; brain network functioning in psychopaths; IQ associated with better predictions
This week, biologists discovered a new cellular organelle that’s like “a new recycling center within the cell.” Wild-growing tomatoes in the Galápagos are de-evolving. And geologists at the University of Southampton detected deep Earth pulses beneath Africa. Plus: Brain network functionality differs in people with psychopathic personality; sharks have a surprising vulnerability; and people with the highest measured IQ make better probabilistic predictions than people with the lowest IQ.
AI is learning to lie, scheme, and threaten its creators
The world’s most advanced AI models are exhibiting troubling new behaviors—lying, scheming, and even threatening their creators to achieve their goals.
In one particularly jarring example, under threat of being unplugged, Anthropic’s latest creation Claude 4 lashed back by blackmailing an engineer and threatened to reveal an extramarital affair.
Meanwhile, ChatGPT-creator OpenAI’s o1 tried to download itself onto external servers and denied it when caught red-handed.
Cancer cells get power boost by stealing mitochondria from nerves
Cancer cells turbocharge themselves by stealing the energy-producing units from neurons in tumours, scientists report today in Nature 1. This act of thievery seems to give cancer cells a boost to help them survive when they metastasize, or spread to distant organs.
The findings show that cancer cells siphon off neurons’ mitochondria — organelles that generate most of a cell’s energy — through ultrathin tubes that grow between the two types of cell. The purloined mitochondria increase cancer cells’ ability to withstand the stress of shooting through blood vessels during metastasis.
“Now we have a new culprit for metastasis, which means we have a new target to block metastasis,” says study co-author Simon Grelet, a cancer neurobiologist at the University of South Alabama in Mobile. “And metastasis is what make cancers so deadly.”
The theft probably helps the cells to spread around the body, and preventing it could provide a path to treatment, researchers say.
An Alaskan volcano could help scientists understand why ‘stealthy’ volcanoes erupt without warning
When volcanoes are preparing to erupt, scientists rely on typical signs to warn people living nearby: deformation of the ground and earthquakes, caused by underground chambers filling up with magma and volcanic gas. But some volcanoes, called “stealthy” volcanoes, don’t give obvious warning signs. Now scientists studying Veniaminof, Alaska, have developed a model which could explain and predict stealthy eruptions.
