Watching too much TV in midlife may shrink the brain

Watching too much TV in midlife may shrink the brain

Watching television very often in midlife may be linked to troubling brain changes decades later. In a study of about 1,700 adults, frequent TV viewers later showed smaller brain regions involved in memory, decision-making, and visual processing, along with more signs of damage in the brain’s white matter. Surprisingly, sitting itself did not appear to be the main issue, since people who spent long hours seated at mentally engaging jobs often showed healthier brain patterns.

China’s Chang’e-6 reveals why solar wind hits the Moon’s two sides differently

China’s Chang’e-6 reveals why solar wind hits the Moon’s two sides differently

China’s Chang’e-6 samples have uncovered a surprising difference between the Moon’s two hemispheres. Solar wind particles penetrated deeper into the far-side soil because Earth’s magnetosphere slows the particles that reach the near side. Noble gases locked inside the lunar regolith preserved evidence of this uneven bombardment. These gases may even help scientists reconstruct the ancient history of Earth’s magnetic shield.

Ancient DNA reveals a chilling secret at China’s 4,000-year-old Shimao city

Ancient DNA reveals a chilling secret at China’s 4,000-year-old Shimao city

Ancient DNA from China’s vast 4,000-year-old Shimao settlement is revealing how one of East Asia’s earliest complex societies was organized. Researchers found that its people were largely descended from local Yellow River farming communities, but also had genetic ties to distant southern and steppe populations, pointing to extensive prehistoric contact.

A hidden “switch-off” signal could predict solar storms seven years early

A hidden “switch-off” signal could predict solar storms seven years early

A newly discovered turning point in the Sun’s 11-year cycle could allow scientists to predict future solar activity years earlier than before. At this “switch-off” point, the most violent space weather abruptly ends, and the remaining number of sunspots offers clues about the next cycle’s strength. Early projections suggest Solar Cycle 26 may be moderate, but a clearer forecast is expected in about two years.

Atlassian: Research shows organizations should approach AI at the team level, not the individual level, to achieve true ROI

Atlassian: Research shows organizations should approach AI at the team level, not the individual level, to achieve true ROI

Presented by Atlassian Most companies are approaching AI adoption backwards by optimizing how individuals use AI instead of how teams work together, said Dr. Molly Sands, head of the Teamwork Lab at Atlassian, during a fireside chat with VentureBeat senior technology contributor Sam Witteveen at VB Transform 2026 . Sands leads a team of behavioral scientists and psychologists who study how AI is reshaping the way people work together, using those findings to help organizations redesign how work gets done. "We don't just study it, we also actively go in and change it," she explained. Her teams teach new ways of working and remap how work flows across companies, a challenge that many organizations are still struggling with, she said. Why AI speed isn’t translating into ROI Atlassian's annual State of Teams Report, which this year surveyed 12,000 global knowledge workers and interviewed roughly 200 Fortune 1000 executives, found a significant disconnect between activity and value, showing that everyone is using AI, while very few can yet locate where it pays off. "89% of those executives told us that individuals are speeding up in their companies, and only 6% of them said they could point to specific examples of clear ROI," Sands said. But roughly 14% of teams had translated AI usage into real value — meaning a single organization could contain a handful of high-performing teams surrounded by others seeing no return at all. Those leading teams shared three characteristics: context, workflows and culture. The teams pulling ahead were building what Atlassian calls a context graph by capturing goals, decisions, and organizational knowledge in shared digital records rather than leaving them in individual memory. Across products such as Jira and Confluence, the graph connects work items, goals and the people doing them, giving AI access to the organizational context it needs. On workflows, the winning teams redesigned entire end-to-end processes rather than simply accelerating isolated tasks. Otherwise, speeding up individuals who are pointed in slightly different directions only causes them to “very quickly start to crash into each other,” as Sands puts it. On culture, the fastest-moving teams worked under leaders who explicitly encouraged learning and experimentation, while making it clear that some experiments would fail. How leaders can move AI from individual hack to team advantage Experimentation and constraints are the fastest route to learning, Sands said. The teams seeing the biggest gains were deliberately imposing constraints on how they worked, from breaking every task into the smallest practical unit of work (a single story point) to committing to write no code by hand for a week. "Most of it is not sustainable to do forever, but it is a really, really fast way to learn," she said. Sands argued that another obstacle isn’t the technology itself but the fact that employees are figuring out AI on their own. Every worker develops different prompts, agents and assumptions, creating another layer of unspoken knowledge inside teams that rarely translates into organizational performance. To counter that, Atlassian experimented with AI working agreements at the start of projects, asking teams to decide not only what they would use AI for, but what they would deliberately avoid using it for, which agents they would share and what common skills would keep everyone working from the same context. Teams that adopted the practice used AI more, moved faster, made better decisions and ultimately produced higher-quality work. The broader lesson, Sands said, is that AI isn’t creating entirely new management problems so much as exposing old ones. Teams have always struggled with hidden assumptions and different mental models of their work. AI simply makes those gaps more consequential, increasing the importance of shared context and explicit ways of working.
