“” Martyr Fakhrizadeh was driving when a weapon, using an advanced camera, zoomed in on him,” Fadavi said, according to Reuters.
“Some 13 shots were fired at martyr Fakhrizadeh with a machine gun controlled by satellite… During the operation artificial intelligence and face recognition were used,” he said. “His wife, sitting 25 centimeters away from him in the same car, was not injured.”
“The machine gun was placed on a pick-up truck and was controlled by a satellite,” he added.”

Capt. Amy Bauernschmidt previously made Navy history as the first woman to become the second-in-command aboard a US carrier.
Ineurals — advanced neuro-technologies for rapid learning and skill acquisition.
The 711th Human Performance Wing, under the U.S. Air Force Research Laboratory leads the development, integration, and delivery of Airman-centric research, education, and consultation enabling the U.S. Air Force to achieve responsive and effective global vigilance, global reach, and global power now and in the future. It’s comprised of the United States Air Force School of Aerospace Medicine and the Airman Systems Directorate, whose science and technology competencies include Training, Adaptive Warfighter Interfaces, Bioeffects, Bioengineering, and Aerospace and Operational Medicine.
MMA champ and legend discussing his longevity in the sport.
Mr. Ken Shamrock is the very first athlete elected to the Ultimate Fighting Championship (UFC) Hall of Fame, widely regarded as one of the biggest stars in the history of Mixed Martial Arts (MMA), as well as an icon and pioneer of the sport.
Hypersonic flight is conventionally referred to as the ability to fly at speeds significantly faster than the speed of sound and presents an extraordinary set of technical challenges. As an example, when a space capsule re-enters Earth’s atmosphere, it reaches hypersonic speeds—more than five times the speed of sound—and generates temperatures over 4,000 degrees Fahrenheit on its exterior surface. Designing a thermal protection system to keep astronauts and cargo safe requires an understanding at the molecular level of the complicated physics going on in the gas that flows around the vehicle.
Recent research at the University of Illinois Urbana-Champaign added new knowledge about the physical phenomena that occur as atoms vibrate, rotate, and collide in this extreme environment.
“Due to the relative velocity of the flow surrounding the vehicle, a shock is formed in front of the capsule. When the gas molecules cross the shock, some of their properties change almost instantaneously. Instead, others don’t have enough time to adjust to the abrupt changes, and they don’t reach their equilibrium values before arriving at the surface of the vehicle. The layer between the shock and heat shield is then found in nonequilibrium. There is a lot that we don’t understand yet about the reactions that happen in this type of flow,” said Simone Venturi. He is a graduate student studying with Marco Panesi in the Department of Aerospace Engineering at UIUC.
Stanford University engineers have developed an airborne method for imaging underwater objects by combining light and sound to break through the seemingly impassable barrier at the interface of air and water.
The researchers envision their hybrid optical-acoustic system one day being used to conduct drone-based biological marine surveys from the air, carry out large-scale aerial searches of sunken ships and planes, and map the ocean depths with a similar speed and level of detail as Earth’s landscapes. Their “Photoacoustic Airborne Sonar System” is detailed in a recent study published in the journal IEEE Access.

Radar and LiDAR have been incredibly quick and effective tools for mapping and surveying the Earth’s surface from aircraft and satellites, but while they can deliver accurate readings through cloud and even forest canopy cover, they can’t tell you what’s below the surface of the sea. Seawater absorbs far too much of the signal.
Sonar remains the most effective way to map out the sea floor – but the vast majority of the oceans that form 70 percent of the Earth’s surface remain unmapped, because sonic waves have hitherto only been able to be sent out from underwater. Sound waves sent from air into water lose more than 99.9 percent of their energy in the translation; it’s why the outside world goes so wonderfully silent when you dive down to the bottom of the pool. The meagre remaining 0.1 percent of the energy does create a sonar signal, but that loses a further 99.9 percent of its energy upon coming back up from the water into the air.

COVID-19 Research: Chinese researchers from the Beijing Institute of Biotechnology, Academy of Military Medical Sciences (AMMS)-China led by Professor Dr Wei Congwen, have found the role of an HDL (high-density lipoprotein) receptor in the facilitation of entry of the SARS CoV-2 into human host cells.
The SARS-CoV-2 infects host cells through binding of the viral spike protein (SARS-2-S) to the cell-surface receptor angiotensin-converting enzyme 2 (ACE2).
