Using cosmic rays to generate and distribute random numbers and boost security for local devices and networks

Posted by in categories: computing, encryption, military, quantum physics

State-of-the-art methods of information security are likely to be compromised by emerging technologies such as quantum computers. One of the reasons they are vulnerable is that both encrypted messages and the keys to decrypt them must be sent from sender to receiver.

A new method—called COSMOCAT—is proposed and demonstrated, which removes the need to send a since cosmic rays transport it for us, meaning that even if messages are intercepted, they could not be read using any theorized approach. COSMOCAT could be useful in localized various bandwidth applications, as there are limitations to the effective distance between sender and receiver.

In the field of information communication technology, there is a perpetual arms race to find ever more secure ways to transfer data, and ever more sophisticated ways to break them. Even the first modern computers were essentially code-breaking machines used by the U.S. and European Allies during World War II. And this is about to enter a new regime with the advent of quantum computers, capable of breaking current forms of security with ease. Even security methods which use quantum computers themselves might be susceptible to other quantum attacks.

Researchers will shoot a projectile at 9,000 miles an hour for science

Posted by in categories: engineering, military, science

The study is being funded by the U.S. Army and Air Force.

Researchers at the Case Western Reserve University in the U.S. are currently working toward an experiment that will record something that has never been captured at such a resolution before; the moment of impact when a projectile traveling at 9,000 miles (14,484 km) an hour hits a wall of water, a press release said.

Research of this nature has been done earlier, but that was nearly eight decades ago. Back in the 1940s, the U.S. military conducted such studies to gauge the impact of shockwaves from underwater explosions on boats and submarines.

A drone that never lands? Scientists in China test lasers to keep drones aloft ‘forever’

Posted by in categories: drones, military

The method would charge drones while their airborne, meaning they would never have to land.

A team of researchers from the Northwestern Polytechnical University (NPU) in China has developed a method for using high-energy laser beams to keep drones airborne “forever,” according to a report from The South China Morning Post.

Laser-powered drones could remain aloft “forever”.

Ramses III against the Sea Peoples

Posted by in category: military

Usermaatre Meryamun, better known as Ramses III (1184 – 1,153 BC), was the second and most important king of the Twentieth Dynasty (1186 – 1,069 BC).

The particularities of his extensive reign, the significance of his military victories against the so-called “Sea Peoples”, and the magnificent state of preservation of his funerary temple in Medinet Habu (Western Thebes) made him one of the most important pharaohs of all the period of the Egyptian New Kingdom (approx. 1,550 – 1,069 BC).

The Eccentricities of J. Robert Oppenheimer

Posted by in categories: chemistry, cosmology, military, particle physics, quantum physics

The so-called “Father of the Atomic Bomb” J. Robert Oppenheimer was once described as “a genius of the nuclear age and also the walking, talking conscience of science and civilization”. Born at the outset of the 20th century, his early interests in chemistry and physics would in the 1920s bring him to Göttingen University, where he worked alongside his doctoral supervisor Max Born (1882−1970), close lifelong friend Paul Dirac (1902−84) and eventual adversary Werner Heisenberg (1901−76). This despite the fact that even as early as in his youth, Oppenheimer was singled out as both gifted and odd, at times even unstable. As a child he collected rocks, wrote poetry and studied French literature. Never weighing more than 130 pounds, throughout his life he was a “tall and thin chainsmoker” who once stated that he “needed physics more than friends” who at Cambridge University was nearly charged with attempted murder after leaving a poisoned apple on the desk of one of his tutors. Notoriously abrupt and impatient, at Göttingen his classmates once gave their professor Born an ultimatum: “either the ‘child prodigy’ is reigned in, or his fellow students will boycott the class”. Following the successful defense of his doctoral dissertation, the professor administering the examination, Nobel Laureate James Franck (1882−1964) reportedly left the room stating.

“I’m glad that’s over. He was at the point of questioning me”

From his time as student at Harvard, to becoming a postgraduate researcher in Cambridge and Göttingen, a professor at UC Berkeley, the scientific head of the Manhattan project and after the war, the Director of the Institute for Advanced Study, wherever Oppenheimer went he could hold his own with the greatest minds of his age. Max Born, Paul Dirac, John von Neumann, Niels Bohr, Albert Einstein, Kurt Gödel, Richard Feynman, they all admired “Oppie”. When he died in 1967, his published articles in physics totaled 73, ranging from topics in quantum field theory, particle physics, the theory of cosmic radiations to nuclear physics and cosmology. His funeral was attended by over 600 people, and included numerous associates from academia and research as well as government officials, heads of military, even the director of the New York City Ballet.

China’s Deadly Covid Wave Leaves Mountains of Body Bags

Posted by in categories: bitcoin, military

China has sent a record number of warplanes near Taiwan in retaliation for what the CCP considers the US arming Taiwan. Covid has hit China really, really hard, and the bodies are piling up. The Biden administration is getting tougher on China. Or so the media tells us. Watch this episode of China Uncensored for that and more of this week’s China news headlines.

Military device with biometric database of 2K people sold on eBay for $68

Posted by in categories: government, military, privacy, terrorism

When a German security researcher, Matthias Marx, found a United States military device for sale on eBay—an instrument previously used to identify wanted individuals and known terrorists during the War in Afghanistan—Marx gambled a little and placed a low bid of $68.

He probably didn’t expect to win, since he offered less than half the seller’s asking price, $149.95. But win he did, and after that, he had an even bigger surprise coming, The New York Times reported. When the device arrived with a memory card still inside, Marx was shocked to realize he had unwittingly purchased the names, nationalities, photographs, fingerprints, and iris scans of 2,632 people whose biometric data had allegedly been scanned by US military.

The device allegedly stored not just personal identifiable information (PII) of seemingly suspicious persons, but also of US military members, people in Afghanistan who worked with the government, and ordinary people temporarily detained at military checkpoints. Most of the data came from residents of Afghanistan and Iraq.

The secret lives of T cells: They derive energy from a master regulator that has been poorly understood, until now

Posted by in categories: biotech/medical, military

T cells aren’t the first immune forces on the scene, they arrive after being alerted by other immune system warriors that a microbe has invaded or a cancer has silently seeded.

Exactly how T cells obtain the energy they need to build a massive army in the face of infiltrators has been the subject of speculation, theory and decades-long laboratory inquiries.

Now, scientists are taking a deeper dive into the question, and their investigations are shedding new light on an array of dynamic biological activities that help bolster T cell populations. Their research demystifies how T cells can power their growth and proliferation when disease emerges and T cell strength is in greatest need.
