Slashdot: Gel That Repairs Heart Attack Damage Could Improve Health of Millions
Gel That Repairs Heart Attack Damage Could Improve Health of Millions Published on June 08, 2022 at 05:00PM British researchers have developed a biodegradable gel to repair damage caused by a heart attack in a breakthrough that could improve the health of millions of survivors worldwide. The Guardian reports: Now after years of efforts searching for solutions to help the heart repair itself, researchers at the University of Manchester have created a gel that can be injected directly into the beating heart -- effectively working as a scaffold to help injected cells grow new tissue. Until now, when cells have been injected into the heart to reduce the risk of heart failure, only 1% have stayed in place and survived. But the gel can hold them in place as they graft on to the heart. To prove the technology could work, researchers showed the gel can support growth of normal heart muscle tissue. When they added human cells reprogrammed to become heart muscle cells into the gel, they were able to grow in a dish for three weeks and the cells started to spontaneously beat. Echocardiograms (ultrasounds of the heart) and electrocardiograms (ECGs, which measure the electrical activity of the heart) on mice confirmed the safety of the gel. To gain more knowledge, researchers will test the gel after mice have a heart attack to show they develop new muscle tissue. The study is being presented at the British Cardiovascular Society conference in Manchester.

Rocket Lab Successfully Carries a US Military Satellite Into Orbit
"Resuming launches after a mission failure two months ago, Rocket Lab successfully placed a small U.S. military research and development satellite into orbit Thursday following a fiery liftoff from New Zealand..." reports Spaceflight Now: Heading east from Mahia, the rocket's first stage burned its nine engines for about two-and-a-half minutes, followed by a six-minute firing of the second stage engine to reach a preliminary parking orbit. A kick stage deployed from the the Electron rocket's second stage... Rocket Lab, a California-based company founded in New Zealand, confirmed a good deployment of the U.S. military's small experimental Monolith spacecraft about 52 minutes after liftoff. "Payload deployed, flawless launch and mission by the team!" tweeted Peter Beck, Rocket Lab's founder and CEO. The mission was the 21st flight of a Rocket Lab Electron launch vehicle since 2017, and the eighth to carry a payload for a U.S. military or intelligence agency customer. It was also the first Rocket Lab mission since May 15, when an Electron rocket failed before reaching orbit with two commercial BlackSky Earth-imaging satellites... The May 15 mission was the third time an Electron rocket failed to reach orbit on 20 attempts since 2017.
