Researchers at Duke University Medical Center and Wake Forest University School of Medicine have identified ALDH4A1, a Mitochondrial proline-metabolizing enzyme, as a third structural component of the mitochondrial pyruvate carrier (MPC) complex. Forming a trimeric assembly with MPC1 and MPC2, ALDH4A1 maintains MPC integrity and facilitates pyruvate import into mitochondria.

Mitochondrial pyruvate import serves as a critical step in cellular energy metabolism, linking cytosolic glycolysis to mitochondrial oxidative phosphorylation...

Astrobee is a free-flying robotic system developed by NASA that is made up of three distinct cube-shaped robots. This system was originally designed to help astronauts who are working at the International Space Station (ISS) by automating some of their routine manual tasks.

While Astrobee could be highly valuable for astronauts, boosting the efficiency with which they complete day-to-day operations, its object manipulation capabilities are not yet optimal. Specifically, past experiments suggest that the robot struggles when handling deformable items, including cargo bags that resemble some of those that it might be tasked to pick up on the ISS.

Researchers at Stanford University, University of Cambridge and NASA Ames recently developed Pyastrobee, a simulation environment and co...

The United States on Friday approved the first blood test for Alzheimer’s, a move that could help patients begin treatment earlier with newly approved drugs that slow the progression of the devastating neurological disease.

The test, developed by Fujirebio Diagnostics, measures the ratio of two proteins in the blood. The ratio is correlated with amyloid plaques in the brain—a hallmark of Alzheimer’s that, until now, has been detected only through brain scans or spinal fluid analysis.

“Alzheimer’s disease impacts too many people—more than breast cancer and prostate cancer combined,” said Food and Drug Administration Commissioner Marty Makary.

“Knowing that 10% of people aged 65 and older have Alzheimer’s, and that by 2050 that number i...
