Consciousness is what we can know best and explain least. It is the inner subjective experience of what it feels like to see red or smell garlic or hear Beethoven. Consciousness has intrigued and baffled philosophers. To begin, we must define and describe consciousness. What to include in a complete definition and description of consciousness?

Scientists how now developed a mini tractor beam that can pull atoms and nanoparticles. Scientists have built a real working tractor beam, albeit at a very small scale. The device, which attracts one object to another from a distance, originates in fiction. The term was coined by E. E. Smith who mentioned the technology in his 1931 novel Spacehounds of IPC, and since the 1990s, researchers have worked to make it a reality.

Scientists have created skin for an organic robot that reacts to light and tightens when the robot walks. If you have seen any science fiction movies in your life, the term “organic robot” surely fills you with a mixture of curiosity and alarm (if not outright terror).

The rocket could have its first test in orbit “as soon as 2027.”

Greater diversification could help agriculture withstand climate, economic and geopolitical crises.

“Items in this section have limited availability due to supplier production issues,” “Sorry, temporarily out of stock” and “Sold out” are all signs that became familiar as recent global upheavals exposed how precarious our food supply is.

The COVID-19 pandemic led to bare shelves in supermarkets as shipping routes were cut off. The war in Ukraine has affected the supply of essential grains.

They consist of two blades looping together so that the tip of one blade curves back into the other.

The MIT Lincoln lab has produced some new devices for aircraft and drones that make some impressive efficiency gains and are radically quieter.

“The toroidal propeller allows a small multirotor unpiloted aircraft, or drone, to operate more quietly than current drones that use propeller forms unchanged since the beginning of aviation,” said a statement by the lab.

Boeing has come up with a new advanced airlifter concept with stealth features to meet the growing need for more durable cargo and tanker planes.

Boeing has shown an idea for a tactical, stealth-capable cargo plane with a blended wing body, or BWB. It comes almost two weeks after Frank Kendall, the secretary of the U.S. Air Force, said that having more airlifters and aerial refueling tankers that can survive will be important in future high-end conflicts against near-peer adversaries, especially China.

A revolutionary new form of rocket has just been tested by NASA. Called RDRE, this new propulsion device could make long-term Moon missions viable.

NASA’s propulsion development engineers have built and tested the agency’s first full-scale rotating detonation rocket engine, or RDRE for short. This advanced rocket engine design could change how propulsion systems are built in the future in a big way.

But is biocontamination a possibility?

The European Space Agency (ESA) is using a unique robotic arm to bring back Martian samples to Earth, according to a statement by the organization published on Thursday (Jan .26).
