Researchers have developed a new detector that analyzes antineutrinos emitted by nuclear reactors to monitor their activities from great distances.
This technology, which utilizes the phenomena of Cherenkov radiation, could revolutionize how we ensure reactors are not producing material for nuclear weapons, despite challenges from other environmental antineutrinos.
Humanity could use a nuclear bomb to deflect a massive, life-threatening asteroid hurtling towards Earth in the future, according to scientists who tested the theory in the laboratory by blasting X-rays at a marble-sized ‘mock asteroid’
The system that produced this outburst is referred to as CXOU J005245.0–722844. It was recently identified by members of the Einstein Probe team and confirmed by the Swift team as the seventh-known example of a Be/White Dwarf X-ray binary. Be/White Dwarf binaries are binary systems in which a white dwarf star orbits a hot young star surrounded by a disk of stellar material. Astronomers expect these binaries to be commonly observed, Gaudin said, and the lack of known examples is a mystery.
“Novae are explosions that happen when material from a nearby star is deposited onto the surface of a white dwarf,” Gaudin said. “After enough material has been built up, the surface undergoes rapid thermonuclear fusion which creates the outburst. Most novae are events that reach moderate luminosities and decay over the course of several weeks. This nova is strange not just in its extremely luminous behavior but also in its short duration.”
The thermonuclear reaction during the nova is similar to a massive hydrogen bomb exploding—the explosion produces electromagnetic radiation that can be seen by telescopes on Earth and in orbit around Earth. According to the researchers, the nova was visible at optical wavelengths, or visible light, for just under a week and in X-rays for just under two weeks.
Nets wont do it, nets wont cut it, and to me, nets say: we dont know and we sorta give up. We need One System to be able to engage All Types and All Classes of drones, w/ EMF — RF jammers, Microwaves, Lasers, Projectiles, and Missiles. All acting simultaneously, to engage a So Called Drone Swarm.
Langley’s 633rd Contracting Squadron put out a notice on October 4 asking for information about potential counter-drone netting that could be installed around up to 42 existing open-ended sunshade-type shelters at the base. Langley, now technically part of Joint Base Langley-Eustis, is one of a select few bases to host F-22s and is a key component of the Air Force’s posture to defend the U.S. homeland.
The 633rd “is in the process of determining the acquisition strategy to obtain non-personal services for the Unmanned Ariel Services (UAS) Netting for East Ramp Metal Sunshades,” according to the contracting notice. “The intention of the netting is to deter and ultimately prevent the intrusion of UAS’s near airmen and aircraft. This initial sunshade netting installation on the metal sunshade (bay Alpha 1) shall serve as a proof of concept for the remaining sunshades.”
France and Germany are joining the coalition at a time of heightened tension in space, with both China and Russia demonstrating their ability to disrupt or destroy satellites. Operation Olympic Defender aims to deter such actions through collective defense, shared intelligence, and the promotion of international norms for responsible space activity.
Germany’s official entry into Operation Olympic Defender was marked by a formal ceremony in Berlin, where Whiting joined Lt. Gen. Gunter Schneider, director-general for military strategy and operations at the German Ministry of Defence, and representatives from Australia, Canada, New Zealand and the United Kingdom.
“Space is truly a team sport. The addition of Germany to our roster of growing like-minded partners contributes to our collective ability to address the growing threats in the domain,” said Whiting.
Medical Countermeasures For Exotic Viral Diseases — Dr. Jay Hooper, Ph.D. — Chief, Molecular Virology Branch, U.S. Army Medical Research Institute of Infectious Diseases — USAMRIID.
Dr. Jay Hooper, Ph.D is Chief, Molecular Virology Branch, at the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID — https://usamriid.health.mil/) where his research is aimed at the discovery and development of medical countermeasures targeting exotic viral diseases of military importance including hemorrhagic fever caused by hantaviruses, arenaviruses, filoviruses (e.g., Ebola virus), and diseases caused by poxviruses (e.g., smallpox and monkeypox).
Dr. Hooper’s discoveries include one of the world’s most potent monoclonal antibodies targeting smallpox (7D11), and the first practical lethal disease animal model for a hantavirus (Andes virus in Syrian hamsters).
Dr. Hooper is an expert in DNA vaccine technology and the use of this technology to develop both active vaccines and passive (antibody-based) medical countermeasures, and is the lead scientist in an effort that has resulted in multiple hantavirus DNA vaccines moving into Phase 1 and 2 clinical trials.
To expedite medical countermeasure research, Dr. Hooper’s group established a pseudovirion neutralization assay capability which has been used to support the rapid development of candidate antibody-based products and vaccines, including candidate Ebola virus vaccines.
The Hunga Tonga underwater volcano was one of the largest volcanic eruptions in history, and now, two years later, new research from The Australian National University (ANU) has revealed its main trigger. The research is published in the journal Geophysical Research Letters.
