NASA, SpaceX launch US–European satellite to monitor Earth’s oceans

About the size of a full-size pickup truck, a newly launched satellite by NASA and its partners will provide ocean and atmospheric information to improve hurricane forecasts, help protect infrastructure, and benefit commercial activities, such as shipping.

The Sentinel-6B satellite lifted off aboard a SpaceX Falcon 9 rocket from Launch Complex 4 East at Vandenberg Space Force Base in central California at 9:21 p.m. PST on Nov. 16. Contact between the satellite and a ground station in northern Canada occurred about 1 hour and 30 minutes later at 10:54 p.m. All systems are functioning normally.

“Understanding tidal patterns down to the inch is critical in protecting how we use our oceans every day on Earth,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “Sentinal-6B will build upon the legacy of Sentinel-6 Michael Freilich by making sea level measurements that improve forecasts used by communities, businesses, and operations across the country. It also will support a safer reentry for our astronauts returning home, including crew from Artemis Moon missions.”

Hidden high-energy water reveals a new molecular force

Water trapped inside tiny molecular cavities behaves in a surprisingly energetic way, pushing outward like people crammed in an elevator. When a new molecule enters these narrow spaces, the confined water forces its way out—boosting the strength of the molecular bond that forms in its place. Researchers from KIT and Constructor University have now proven this effect both experimentally and theoretically, showing that these “highly energetic” water molecules can dramatically influence how other molecules interact.

Function of the Spine

Your spine is an important bone structure that supports your body and helps you walk, twist and move. Your spine is made up of vertebrae (bones), disks, joints, soft tissues, nerves and your spinal cord. Exercises can strengthen the core muscles that support your spine and prevent back injuries and pain.

Ultrasonic device dramatically speeds harvesting of water from the air

MIT engineers designed an ultrasonic system to “shake” water out of an atmospheric water harvester.


MIT researchers designed a device that quickly recovers drinking water from an atmospheric water harvesting material. The system uses ultrasonic waves to shake the water out of the material, recovering water in minutes.

Isolated Cervical Radiculopathy as an Unusual Presentation of Vertebral Artery Dissection

Vertebral artery dissection may present as an isolated cervical radiculopathy sparing the central nervous system—an unusual presentation requiring differentiation from Parsonage-Turner syndrome, thoracic outlet syndrome, and other etiologies of cervical radiculopathy.

Electric Fields Steer Nanoparticles for Targeted Drug Delivery

Researchers discovered a new way to independently tune a nanoparticle’s speed and direction using different strength electric fields.

The new method could lead to better drug delivery technologies.
