MIT researchers have built a small robot that can move through both air and water using the same set of wings โ and switch between the two without any extra hardware. Inspired by diving seabirds like puffins, the robot weighs about half a pound and has a wingspan just shy of three feet. Its wings are made from translucent nylon fabric reinforced with carbon fiber struts, giving them enough flexibility to work in both environments.
Instead of sealing the entire body, each component is waterproofed individually โ water floods the central structure, keeping the robot neutrally buoyant underwater. In testing at Lake Geneva, the robot transitioned from water to air in less than a second. Glenna Clifton, an animal movement biologist, called it "a monumental step in the performance at both swimming, flying, and transitioning between the two." The team hopes future versions could monitor coastal environments, tracking algal blooms or observing marine life.

OpenAI's GPT-5.6 Sol Ultra has produced a complete proof of the Cycle Double Cover Conjecture, a graph theory problem that had remained open since the 1970s. The proof came entirely from the AI, using 64 sub-agents working in parallel. Mathematician Thomas Bloom of the University of Manchester called it "a very nice proof" โ short, elementary, and something that "could have been discovered in the 1980s."
So why didn't humans find it? Bloom suspects the key step involved a small, counterintuitive twist. A human mathematician would have tried the obvious approach, seen it fail, and moved on. The AI "does not get discouraged and keeps trying small variations until one clicks." However, Bloom criticized the AI for failing to cite prior work from a 1983 paper that likely influenced the proof โ a recurring issue with AI-generated research. The prompt itself was engineered to force persistence: the model was told to compute for at least eight hours before even considering giving up.

Scientists have built a synthetic cell that grows, replicates its DNA, and divides โ the strongest demonstration yet that nonliving materials can be coaxed into lifelike behavior. Led by synthetic biologist Kate Adamala at the University of Minnesota, the team assembled biological components piece by piece inside a lipid membrane. The result is not technically alive, but it performs the basic functions of a complete cell cycle.
"It's a big step forward to this holy grail of making a living thing out of dead components," said Sijbren Otto, a systems chemist not involved in the work. Because every molecular part was crafted in the lab, scientists can swap components in and out โ a flexibility that could eventually lead to custom cells that produce biofuels, drugs, or new materials. The work also speaks to one of science's deepest questions: how could life have emerged from nonlife some 4 billion years ago?

The 21st Century Road to Housing Act โ a bipartisan bill combining 47 separate proposals โ officially became law on Saturday, marking the most comprehensive housing reform in at least three decades. The law aims to tackle the nation's housing shortage by boosting supply: it promotes manufactured housing, office-to-apartment conversions, and grants for fixing older homes that have fallen into disrepair.
President Trump, who had previously expressed support, refused to sign the bill and called it a "big yawn" in a last-minute reversal over an unrelated political fight. But because he did not veto it, the measure became law automatically under the Constitution. Experts caution that immediate relief is unlikely โ building new homes takes time, and local zoning laws remain the biggest bottleneck. "Congress has chosen not to preempt local and state governments and tell them what to do," said housing researcher Yonah Freemark.

Gaia Alari, a 36-year-old artist living in Bergamo, Italy, had watched her 77-year-old father grow increasingly frail with age. Confronted with his mortality, she began searching for a way to make losing him less painful โ and discovered a technology that lets you create a virtual replica of a loved one, trained on their voice, mannerisms, and memories.
The resulting AI companion raises profound questions about grief, memory, and what we owe the dead. Is a digital ghost a comfort or a refusal to let go? As the technology becomes more accessible, a growing number of people are grappling with the same choice โ turning to artificial intelligence not for productivity or entertainment, but to preserve the people they cannot bear to lose.
