1  China landed a reusable rocket booster vertically on a floating platform, joining SpaceX and Blue Origin in an exclusive club.

The Long March 10B booster touched down successfully six minutes after stage separation, landing on a sea platform in what is the first successful vertical recovery of a Chinese orbital rocket. The Long March 10B carries at least 16 metric tons to low-Earth orbit, comparable to SpaceX's Falcon 9, which now launches roughly 150 times a year on the back of reusability. China has spent years closing the gap on this specific capability. This landing confirms the gap is closed. Watch it happen.

2  New models suggest Earth has a better chance of surviving the Sun's expansion than astronomers previously calculated.

Research from KU Leuven revised the models that predict what happens to nearby planets when a star enters its red giant phase. The updated calculations show weaker tidal forces than older models assumed, which gives Earth more room to drift outward as the dying Sun sheds mass rather than being absorbed. The researchers are careful to note that better stellar observations are needed before any firm conclusion, but the direction of the revision is hopeful.

3  A 17-year-old trained an AI on retinal scans that distinguishes between autism, ADHD, and neurotypical patients at 89% accuracy.

Edward Kang's RetinaMind uses image-analysis models trained on retinal scans to classify patients across three categories, with built-in explainability showing which regions of the retina influenced each prediction. Kang also mapped the genetic pathways connecting retinal structure to neurodevelopmental differences. A non-invasive screening tool that works at this accuracy level from a routine eye scan could meaningfully reduce the waiting times children currently face before receiving a diagnosis.

4  Scientists watched new ocean floor form in real time for the first time in recorded history.

In 2024, a swarm of earthquakes in the Indian Ocean caused tectonic plates to separate abruptly, adding more than three feet of new seafloor in a single event. Instruments were already in place two months before the earthquakes struck, giving researchers the most detailed live observation of crustal formation ever recorded. The findings, published this week, rewrite what geologists understood about the speed and mechanism of seafloor spreading.

Google Home Speaker ($99). A Gemini-powered smart speaker that handles connected device control, question answering, and routine management. The $99 price positions it as Google's entry-level response to Amazon Echo, but with a more capable AI assistant underneath.

Epomaker RT98. A retro mechanical keyboard with a detachable numpad that can sit on either side of the board, a built-in display for system stats or animations, and full layout customization. For anyone who has wanted a compact mechanical keyboard that does not sacrifice the numpad entirely, this covers the gap.

Schlage Sense Pro. A smart lock that unlocks automatically as an authorized user approaches and supports Apple Home Key for hands-free or tap access via iPhone or Apple Watch. Hands-free entry has been the practical argument for smart locks that most earlier products failed to deliver convincingly.

MemoMind One. Camera-free smart glasses with a micro-LED display that projects a private screen into the wearer's field of view. They include AI features, audio playback, notification mirroring, and hands-free information access, without a camera, which removes the privacy concern that has limited adoption of most AR glasses.

Why traffic jams happen with no cause. A Japanese experiment demonstrated that even a perfectly clear road with consistent drivers will produce a traffic jam spontaneously. The mechanism has nothing to do with obstacles. It is a property of how individually reasonable behaviors aggregate into collective dysfunction.

The $1B typo. In 1992, a software error in Pepsi's Philippine promotional campaign convinced 800,000 people they had won the lottery. What followed involved lawsuits, riots, and one of the most expensive accidental promotions in corporate history.

Stadium atmosphere, no ticket required. A bar installed a screen large enough and curved enough to recreate the visual experience of sitting inside a stadium. The effect is disorienting in a way that photographs do not fully convey. The clip has been circulating widely ahead of the World Cup.

Concrete that refuses water. Engineers developed a hydrophobic concrete surface that actively repels water. The video of droplets bouncing off looks more like a visual effect than an actual material. It is neither. The applications for infrastructure drainage and building maintenance are substantial.

MIT moves your fingers for you. A resurfaced MIT project uses electrical muscle stimulation to guide a wearer's hands through complex physical movements in real time, including tasks the wearer has never learned. The implications for physical skill transfer and rehabilitation are the part most people do not get to before they stop watching.
