Addressing one of the most profoundly unanswered questions in biology, a Rutgers-led team has discovered the structures of proteins that may be responsible for the origins of life in the primordial soup of ancient Earth.
The researchers explored how primitive life may have originated on our planet from simple, non-living materials. They asked what properties define life as we know it and c New spheres of knowledge on the origin of life

The shape of a cell affects its physical and chemical properties. Different cell types have developed different shapes to enable effective functioning. But what shape were the very first cells, as life began to evolve?
Primitive cells are thought to have been spherical, but experimental evidence supporting this belief remains elusive. Now, however, researchers from the University of Tsukub Carnegie Mellon-led team to develop robotics to service satellites and build structures

There are 6,500 satellites in orbit, but only about half of them are functional. Once a satellite breaks down or runs out of fuel, it is essentially useless. Repairs, maintenance and upgrades are nearly impossible in orbit.
It's launch once, use once. But as satellites have become more robust, their operators often find that fleets outlast their projected lifespans and need new technology, NASA satellite servicing technologies licensed by Northrop Grumman

Northrop Grumman recently signed agreements to license three technologies from NASA related to satellite servicing.
Two of the technologies were developed by NASA for the On-orbit Servicing, Assembly, and Manufacturing 1 (OSAM-1) mission. OSAM-1 is a first-of-its-kind mission that will grapple a US government-owned satellite, Landsat 7, to refuel it and to demonstrate the capability to pot New AI navigation prevents crashes

What do you call a broken satellite? Today, it's a multimillion-dollar piece of dangerous space junk. But a new collision-avoidance system developed by students at the University of Cincinnati is getting engineers closer to developing robots that can fix broken satellites or spacecraft in orbit.
