Nearly 50 years after it was collected, a lunar sample from the Apollo 17 mission has finally been opened at NASA’s Johnson Space Center in Houston. It’s one of the last unopened samples from the final Apollo mission to land humans on the moon.

“We have had an opportunity to open up this incredibly precious sample that’s been saved for 50 years under vacuum and we finally get to see what treasures are held within,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate in Washington, in a statement.

It was collected by NASA astronauts Eugene Cernan and Harrison “Jack” Schmitt in December 1972 when they hammered 14-inch (36-centimeter) cylindrical drive tubes into a landslide deposit in the Taurus-Littrow Valley. The two astronauts vacuum-sealed the tube while still on the lunar surface.

Boston medical researchers in a new groundbreaking study have discovered a “vicious cycle” between daytime napping and Alzheimer’s dementia.

The Brigham and Women’s Hospital researchers found a link between the two: Excessive daytime napping predicted an increased future risk of Alzheimer’s dementia, and a diagnosis of Alzheimer’s dementia sped up the increase in daytime napping during aging.

Daytime napping is common among older adults, but researchers have not known the relationship between daytime napping and cognitive aging.

Techniques from computer science may help explain the tendency in biology for structures to repeat themselves.

The study could provide hope for people who have locked-in syndrome. But the study author’s track record is mired with controversy.

To develop the hypersonic vehicles of the future, we need to properly understand how to predict boundary layer transition on realistic vehicle shapes and what the minute effects of turbulent flow on hypersonic vehicles are. Data from the BOLT II flight experiment will help do just that.

Both the BOLT and BOLT II vehicles have a complex, swept geometry with a concave surface to represent a real hypersonic vehicle. The aim is to produce complex, real-world data that engineers and scientists can use to improve their models for predicting transition on hypersonic vehicles.

A separate experiment is run on each side of the vehicle, with one “smooth” side and one “rough” side. The flow running length along the vehicle is 1 meter, slightly larger than the original BOLT vehicle.

At GTC 2022, Nvidia CEO Jensen Huang finally shared more details around the company’s Arm endeavors as he unveiled the company’s new 144-core Grace CPU Superchip, the company’s first CPU-only Arm chip designed for the data center. The Neoverse-based system supports Arm v9 and comes as two CPUs fused together with Nvidia’s newly branded NVLink-C2C interconnect tech. Nvidia claims the Grace CPU Superchip offers 1.5X more performance in a SPEC benchmark than two of the last-gen 64-core AMD EPYC processors in its own DGX A100 servers, and twice the power efficiency of today’s leading server chips. Overall, Nvidia claims the Grace CPU Superchip will be the fastest processor on the market when it ships in early 2023 for a wide range of applications, like hyperscale computing, data analytics, and scientific computing.

Nvidia unveiled its new 144-core Arm-based Grace CPU Superchip at GTC 2022 along with a host of new interconnect technologies.

At GDC 2022 this week, VR glove creator Manus revealed its new Quantum Metagloves which the company says delivers significantly more accurate finger tracking than its prior solutions. Though priced for enterprise use, the company says it one day hopes to deliver the tech to consumers.

Manus has been building motion gloves for use in real-time VR and motion capture for years now, with prior offerings being based on IMU and flex-sensor tracking.

American Robotics CEO Reese Mozer has no beef with drone deliveries, but he thinks all the hoopla surrounding aerial transport of burgers and burritos is drowning out news about farther-reaching UAV activities that are dramatically changing the way businesses operate. He tells DroneDJ about that transformative innovation, and how American Robotics’s (AR) leading role in the complete automation of critical drone services to industry is set to take wing.

Nevertheless, Mozer adds, that action manages to generate sufficient media and public excitement to divert attention from the more complex, vital, and – in total financial terms – valuable surveying and inspection services drone automation provides heavy industry, energy, railroad, and infrastructure operators. And that’s precisely the UAV sector activity he predicts will begin taking off and turning heads this year.
