A vibrant green nebula in outer space with countless stars shining bright

Twenty-second views of James Webb deep-space images and star fields in a 113-person study were linked to higher awe, stronger feelings of vastness and restoration and no rise in negative emotion when the same people later rated urban scenes

Twenty seconds was enough to move the numbers. In a two-part psychology study with 113 participants, people who looked at sets of James Webb Space Telescope deep-space images and ordinary star-filled night skies reported more awe than when they looked at urban scenes with no obvious greenery or water. The rise showed up in both…

Power rose and benevolence dipped for 12 astronauts midway through 4 to 7 month ISS missions, while perceived gaps across seven personal values tracked where crew tension was most likely to grow

Twenty percent shorter inner minutes appeared in orbit while memory for docking and spacewalk dates stayed close to Earth time and a 10-astronaut study on the International Space Station suggests that routine duration judgments can drift even when mission milestones remain firmly tracked

ISS cosmonauts spoke to Mission Control more than twice as much during heavy workloads, while negative emotion signals rose fivefold across 164,658 statements, suggesting that long missions may require stronger support from the ground

Freedivers who trained without breath three times a week for seven months kept stable hippocampal volumes and normal episodic memory, as MRI scans in 17 divers and 20 other athletes found no detectable damage from repeated voluntary hypoxia and no change in how the brain sorted similar experiences

In a 392-patient dental clinic trial, adults waiting near fish rated the room more favorably, but the aquarium did not measurably lower anxiety, mood scores, blood pressure, or heart rate before treatment

Twenty-two divers played a gambling game 100 feet underwater and the deeper group kept picking the losing decks while previous dive count offered no clear protection, a sign that nitrogen narcosis may bend judgment before people notice it

Sixty days of head-down bed rest changed brain signals while harder task scores held steady and two 30-minute artificial-gravity regimens neither hurt nor clearly improved thinking in a 22-person analysis built to prepare humans for longer space missions

Sixty days in a strict head-down bed rest study left volunteers with an unexpected split result: their harder working-memory style tasks did not collapse, yet the brain signals behind attention and target detection still shifted. For a field that worries about concentration, judgment and mental endurance on long missions, that combination is more revealing than…

Plastic waste and litter scattered on a sandy beach, highlighting environmental pollution issues

Oceans Explainer

Across 138 volunteers, as few as 10 to 21 litter items on a beach scene were enough to lower calm, happiness and the sense of restoration people expected from the coast and the sharpest drop came when the mess looked like careless public behavior instead of working gear from fishing

A clean shore can feel like a reset button, yet this study found that the feeling is fragile. When researchers added small amounts of debris to beach photographs, viewers rated the scenes as less pleasant, less calming and less likely to help them recover from stress. The harshest reactions came when the trash looked as…

Volunteers and children participate in a beach cleanup, promoting environmental awareness

Humans Explainer

Ninety students spent the same 90 minutes on one Devon shore, either walking, rock pooling, or picking up litter and the beach cleaners came away with the strongest sense of meaning even as that volunteer lift and their broader green intentions were already easing one week later

Students who handled other people’s rubbish left the shore feeling more purposeful than the students who simply walked the same coast. A field experiment in southwest England points to a sharp answer: the act of helping was associated with a different kind of coastal experience, even when the setting itself seemed slightly less restful. The…
