After nearly breaking, NASA’s Deep Space Network “worked well” on Artemis II
“Once that is in place, as we move forward with new mission commitments, we will just be more focused, I think, and more process-oriented in being able to commit to new missions or not,” Heckler said. Key antenna offline One constraint on the DSN is an accident last year that knocked one of the network’s

Diabetes org apologizes for ejecting scientists over criticism of Trump
Amid intense backlash, the head of the American Diabetes Association posted a video Wednesday apologizing for the organization’s decision on Friday to forcefully remove five leading diabetes scientists from the association’s annual meeting. The scientists were ejected for handing out copies of an April editorial—published in the ADA’s own journal Diabetes Care—that sharply criticizes the Trump

Three key vital signs make up the “urban pulse” of a city
People often speak metaphorically of the heartbeat or pulse of a city, but according to the authors of a new paper published in the Proceedings of the National Academy of Sciences, cities do indeed have an “urban pulse”—an indication of urban “metabolic activity” that can be measured to suss out telltale patterns. And those patterns

FCC lifts looming deadline for Amazon Leo satellite broadband constellation
The Federal Communications Commission has waived a requirement for Amazon to launch half of its satellite broadband constellation by the end of July, a key regulatory reprieve that buys the tech giant time to get more of its spacecraft into orbit. Amazon won regulatory approval for the Amazon Leo network in July 2020. The FCC’s

The weather and climate science AI revolution isn’t revolutionary
Some limitations should be obvious. This algorithm won’t identify a species it wasn’t trained on or any subpopulations of species that differ too much from the example. The quality of the training data matters a lot, too. If we only use photos of chickadees in pine trees, the model could include pine needles in its

Scientists ejected from diabetes conference for distributing journal reprints
Five leading scientists were ousted from the annual meeting of the American Diabetes Association (ADA) in New Orleans on Friday. Their crime: handing out copies of an editorial, published in the journal Diabetes Care on April 29, sharply criticizing the Trump administration’s ongoing attacks on scientific research. Those ousted were Steven Kahn, professor of medicine

Bumblebees can spontaneously solve problems, study finds
“This design assessed whether bees could solve the task without continuous perceptual feedback,” the authors wrote. All told, 16 of 22 bees succeed in this task. Granted, the bees could still potentially catch a glimpse of the flower once the ball was near the opening, so the team repeated the experiment with three openings in

Used Waymo robotaxi batteries become backup storage for power grids
A 2025 analysis of over 22,700 electric vehicles across 21 models found that average battery capacity loss was about 2.3 percent per year, according to the telematics company Geotab. That translates to such batteries still having more than 81 percent of their original capacity after eight years. Waymo’s current fleet of nearly 4,000 vehicles mainly

Beans use an immune receptor to call in airstrikes on caterpillars
At the same time, the plants unable to detect the molecular signature of the caterpillar’s drool were largely ignored by the wasps. They weren’t completely defenseless, though. “There are other papers that show if you knock out all immune signaling, the caterpillars grow twice as big—they get enormous,” Steinbrenner says. This, he suggests, indicates the
