Rachel Bronson, PhD, president and CEO, Bulletin of the Atomic Scientists, said: “We are living in a time of unprecedented danger, and the Doomsday Clock time reflects that reality. 90 seconds to midnight is the closest the Clock has ever been set to midnight, and it’s a decision our experts do not take lightly. The US government, its NATO allies and Ukraine have a multitude of channels for dialogue; we urge leaders to explore all of them to their fullest ability to turn back the Clock.”

The Doomsday Clock’s time is set by the Bulletin of the Atomic Scientists’ Science and Security Board with the support of the Bulletin’s Board of Sponsors, which includes 10 Nobel Laureates. Previously, the Doomsday Clock had been set at 100 seconds to midnight since 2020.

Nine military officers who had worked decades ago at a nuclear missile base in Montana have been diagnosed with blood cancer and there are “indications” the disease may be linked to their service, according to military briefing slides obtained by The Associated Press. One of the officers has died.

All of the officers, known as missileers, were assigned as many as 25 years ago to Malmstrom Air Force Base, home to a vast field of 150 Minuteman III intercontinental ballistic missile silos. The nine officers were diagnosed with non-Hodgkin lymphoma, according to a January briefing by U.S. Space Force Lt. Col. Daniel Sebeck.

Missileers ride caged elevators deep underground into a small operations bunker encased in a thick wall of concrete and steel. They remain there sometimes for days, ready to turn the launch keys if ordered to by the president.

For the past 60 years, helicopters have provided essential vertical takeoff and landing (VTOL) capabilities–omnidirectional maneuverability, hovering, landing on almost any flat surface–for countless military operations. Even as VTOL aircraft technology continues to advance, however, one key goal still remains elusive: improving top speed beyond 150 kt-170 kt. Faster VTOL aircraft could shorten mission times and increase the potential for successful operations, while reducing vulnerability to enemy attack. Unfortunately, new VTOL designs so far have been unable to increase top speed without unacceptable compromises in range, efficiency, useful payload or simplicity of design.

DARPA has trained one of its robots to identify humans. There’s just one little problem: The robot is cartoonishly easy to confuse.

Violence and warfare were widespread in many Neolithic communities across Northwest Europe, a period associated with the adoption of farming, new research suggests.

Of the skeletal remains of more than 2,300 early farmers from 180 sites dating from around 8,000—4,000 years ago to, more than one in ten displayed weapon injuries, bioarcheologists found.

Contrary to the view that the Neolithic era was marked by peaceful cooperation, the team of international researchers say that in some regions the period from 6000BCE to 2000BCE may be a high point in conflict and violence with the destruction of entire communities.

It generates energy by forcing the stream to form a vortex.

Without employing any blades, the transportable hydraulic turbine SETUR from Vortex Hydrokinetics serves as a power source. The water source could be rivers, tidal streams, ocean currents, or even canals.

We live in an era of renewed space exploration, where multiple agencies are planning to send astronauts to the Moon in the coming years. This will be followed in the next decade with crewed missions to Mars by NASA and China, who may be joined by other nations before long. These and other missions that will take astronauts beyond Low Earth Orbit (LEO) and the Earth-Moon system require new technologies, ranging from life support and radiation shielding to power and propulsion. And when it comes to the latter, Nuclear Thermal and Nuclear Electric Propulsion (NTP/NEP) is a top contender!

NASA and the Soviet space program spent decades researching nuclear propulsion during the Space Race. A few years ago, NASA reignited its nuclear program for the purpose of developing bimodal nuclear propulsion – a two-part system consisting of an NTP and NEP element – that could enable transits to Mars in 100 days. As part of the NASA Innovative Advanced Concepts (NIAC) program for 2023, NASA selected a nuclear concept for Phase I development. This new class of bimodal nuclear propulsion system uses a “wave rotor topping cycle” and could reduce transit times to Mars to just 45 days.

Xerox® Elem™ Additive Solutions today announced that an ElemX liquid metal printer was recently installed on board USS Essex (LHD 2), making it the first metal additive manufacturing machine deployed on a U.S. Naval vessel.

The ElemX was placed on the ship earlier this month in Pearl Harbor, Hawaii, with at-sea trials beginning immediately. The installation is the latest step in the U.S. Navy’s strategy of using additive manufacturing (AM) to increase operational readiness for the fleet. It also builds on the relationship between the U.S. Navy and Xerox Elem Additive that began with the Naval Postgraduate School in Monterey, California receiving the first-ever installation of the ElemX in 2020.

“The military supply chain is among the most complex in the world and putting the ElemX on USS Essex means that sailors can now bypass that complexity and print parts when and where they need them,” said Tali Rosman, GM of Elem Additive. “We are proud to continue our partnership with the Navy to help them advance their additive manufacturing capabilities and execute their long-term vision.”

The world’s second-most powerful rocket—though it’s largest partially renewable rocket—yesterday blasted-off on a secret mission for the US Space Force amid spectacular views. Only the fifth flight of the company’s heavy-life Falcon Heavy rocket (though the second inside a few months), the event took place in twilight Sunday, with a satellite being successfully sent into geosynchronous Earth orbit (meaning it will orbit at the same speed as Earth rotates). Two side-boosters then returned to land in tandem on launch pads.

They were the 163th and 164th successful landings of an orbital-class rocket, according to SpaceX.
