Packed cells may help explain why some cancerous tumors stay put while others break off and spread through the body.

The subtle mechanics of densely packed cells may help explain why some cancerous tumors stay put while others break off and spread through the body.

Thomas Sterling has retracted his prediction that we will never reach ZettaFLOP computers. He now predicts zettaFLOPS can be achieved in less than 10 years if innovations in non-von Neumann architecture can be scaled. With a change to cryogenic technologies, we can reach yottaFLOPS by 2030.

John Bucknell created the pre-conceptual design for the SpaceX Raptor engine. It will be the advanced full-flow staged combustion rocket engine for the SpaceX BFR. He designed and built the subscale Raptor rocket for proof of concept testing able to test eighty-one configurations of main injector.

John Bucknell says the nuclear turbo rocket technology and his designs are ready for development. The air-breathing nuclear thermal rocket will enable 7 times more payload fraction to be delivered to low-earth orbit and it will have 6 times the ISP (rocket fuel efficiency) as chemical rockets. The rocket will have two to three times the speed and performance of chemical rockets for missions outside of the atmosphere.

The fully reusable nuclear rocket will be a single stage to orbit system which will be able to make space-based solar power several times cheaper than coal power. Using the 11-meter diameter version of this rocket to build space-based solar power will enable solar power at less than 2 cents per kilowatt-hour.

Persistent anxiety can contribute to respiratory disorders, gastrointestinal problems, and heart disease. Treating anxiety with psychotherapy, medications, or a combination can reduce or relieve physiological distress.

Ever wonder about the science behind a black hole?

Directly converting electrical power to heat is easy. It regularly happens in your toaster, that is, if you make toast regularly. The opposite, converting heat into electrical power, isn’t so easy.

Researchers from Sandia National Laboratories have developed a tiny silicon -based device that can harness what was previously called waste heat and turn it into DC power. Their advance was recently published in Physical Review Applied.

“We have developed a new method for essentially recovering energy from waste heat. Car engines produce a lot of heat and that heat is just waste, right? So imagine if you could convert that engine heat into electrical power for a hybrid car. This is the first step in that direction, but much more work needs to be done,” said Paul Davids, a physicist and the principal investigator for the study.

Would you put on an exoskeleton that meant you could run for an entire day without getting tired?

What about one that would allow you to stay on your feet longer at work?

Tactical Robotics’ Cormorant drone design allows it to navigate tight areas where a helicopter’s blades would get caught on the environment. The remote-controlled military drone can transport two injured people from a battle zone. The Israeli-based company believes the drone could one day also be used to inspect bridges, deliver medical supplies and spray crops.
