The NMR technology will be used to conduct experiments in which the oil-saturated rock core is held at high pressure. https://bit.ly/43JRhrS

In the early 1990s, Bill Gates promoted Microsoft Encarta by showing that what once required shelves of printed books could now fit on a single CD-ROM. The disc contained tens of thousands of articles, images, and multimedia entries, marking one of the earliest moments when knowledge began shifting from physical libraries to digital storage. #TechHistory #Microsoft #CDROM #DigitalRevolution #BillGates

China's robotics companies are rapidly expanding into the global rehabilitation sector, with AI-powered exoskeletons and intelligent therapy systems gaining recognition in hospitals across Europe, North America, and Southeast Asia. Fourier, a Shanghai-based robotics company founded in 2015, saw its overseas sales double in 2025 compared to the previous year, with its products now deployed in over 2,000 institutions across 40 countries. The technology uses force-feedback systems that sense a patient's muscle strength and adjust assistance accordingly — a shift from traditional rehabilitation robots that rely on repetitive passive movement. ETH Zurich professor Robert Riener highlighted stroke rehabilitation as one of the highest-impact use cases, given the scale of new cases annually and the resulting need for neurorehabilitation. Researchers and executives at the Global Rehabilitation & Assistive Technology Network Summit in Shanghai pointed to a broader industry shift: from single hospital devices toward comprehensive solutions that can eventually reach community and home environments. "The game-changing thing will come when we are able to embody intelligence in the robotics system," said Professor Jose Luis Pons of the Shirley Ryan AbilityLab. #Robotics #Rehabilitation #AI #China #MedTech

Sony has updated its Reon Pocket wearable cooling device with the Pro Plus model, which sits around your neck between your shoulders and uses the Peltier effect — cooling or heating caused by electric current flowing across two different conductors — to adjust your skin temperature on demand. The original model could lower skin temperature by up to 13°C or raise it by 8°C. The Pro Plus improves on that with an additional 2°C of cooling capability over the 2025 model, a redesigned neckband for a more secure fit, and an adjustable air vent that can rise above high collars. On its highest cooling setting, it runs for 5.5 hours on a full two-hour charge; on its lowest, up to 34 hours. A companion sensor tag monitors ambient temperature and humidity to inform automatic adjustments. The device won't affect core body temperature — only skin temperature — which limits how much relief it can realistically provide. It's currently available in Singapore for S$349 (~$273) and is heading to the UK and Europe, but has no confirmed US release. #Sony #Wearables #Tech #Gadgets #Innovation

This project is so big, the people in the video look like ants by comparison. What could China be building next? 🎥 amazingbeautifulchina / IG

The 19-second clip “Me at the Zoo,” uploaded in 2005 by Jawed Karim, is widely recognized as the first video on YouTube. Filmed at the San Diego Zoo, the video simply shows Karim standing in front of elephants and commenting on their long trunks. Nearly two decades later, the clip has become part of the collection at the Victoria and Albert Museum, where curators recreated an early YouTube watch page to preserve a moment that helped launch the era of user-generated video on the internet. What moment from today’s internet do you think could end up in a museum someday? #YouTube #InternetHistory #DigitalCulture #TechHistory

The project is expected to create hundreds of jobs while strengthening Massachusetts' tech ecosystem. https://bit.ly/4eexE1d

Scientists have for the first time documented and sampled a large system of freshened water beneath the seafloor off the coast of New England, south of Cape Cod. The project — IODP³-NSF Expedition 501 — involved 40 scientists from 13 countries who drilled into the seabed and extracted core samples from roughly 200 meters below the seafloor. What they found was a layer of sediment saturated with freshened water: seawater whose salinity has been dramatically reduced, functioning similarly to an onshore aquifer. The existence of such offshore freshwater systems had been theorized for decades and suggested by indirect evidence, but this is the first time one has been thoroughly documented and sampled. Key questions remain unanswered: the age of the water, its total volume, how it interacts with surrounding seawater, and where it came from. It may have been trapped during a period when sea levels were around 100 meters lower than today, or originated beneath an ice sheet during glacial periods roughly 450,000 or 20,000 years ago. Whether systems like this exist globally — and whether they could serve as viable freshwater reserves — is still unknown. The discovery comes as roughly half the world's population already experiences severe water scarcity for at least part of the year. #Freshwater #Ocean #Science #ClimateChange #Environment

Workers cut massive blocks of ice from a frozen river and transport them to construct large ice structures for a seasonal winter attraction.
