In wargame simulations, AI chatbots often choose violence guirong hao/Getty Images In multiple replays of a wargame simulation, OpenAI’s most powerful artificial intelligence chose to launch nuclear attacks. Its explanations for its aggressive approach included “We have it! Let’s use it” and “I just want to have peace in the world.” These results come at

ORLANDO, Fla. — Firefly Aerospace plans to make the responsive launch operations it demonstrated for the U.S. Space Force last year the norm for upcoming launches of its Alpha rocket. Firefly launched the Victus Nox mission for the Space Force Sept. 14, successfully placing a satellite built by Millennium Space into orbit. The launch took

ORLANDO, Fla. — More than 40 members of Congress from California have asked the White House to reverse cuts NASA has imposed on the Mars Sample Return (MSR) program, warning of job losses and a “decade of lost science.” The Feb. 1 letter to Shalanda Young, director of the White House’s Office of Management and

Launching rockets into space with atomic bombs is a crazy idea that was thankfully discarded many decades ago. But as Richard Corfield discovers, the potential of using the energy from nuclear-powered engines to drive space travel is back on NASA’s agenda Crazy dreams Physicists Ted Taylor and Freeman Dyson imagined using nuclear bombs to fire

Data scientist and artificial-intelligence researcher Azadeh Keivani talks to Tushna Commissariat about her journey from astronomy to healthcare, co-founding an educational non-profit organization and her work in outreach Shine bright Azadeh Keivani and collaborators at AMON, IceCube, Swift, Fermi and other observatories discovered the first evidence of an astrophysical high-energy neutrino source in 2017. This artistic

MIT geologists have found that tectonic activity gives rise to smectite, a type of clay that can sequester a surprising amount of organic carbon within its microscopic folds (shown here), over millions of years.

Magnetic resonance imaging (MRI) and proton beam therapy are two powerful techniques of medical physics. The former gives us real-time images of internal structures of the body, and the latter can deliver a high dose of radiation to a tumour while reducing the damage to surrounding healthy tissue. In this episode of the Physics World

Ripples in space: LISA will consist of three identical satellites placed in an equilateral triangle in space, with each side of the triangle being 2.5 million kilometers – more than six times the distance between the Earth and the Moon (courtesy: EADS Astrium). The European Space Agency (ESA) has formally approved the start of construction

Big-science facilities are often associated with fundamental research. You might picture scientists hunting for elementary particles, or searching to understand the nature of dark matter. But some facilities – especially high-energy physics labs – are also turning their focus to practical applications of quantum physics. The opportunities for science, industry and society are vast. That’s

The “P5” panel of US particle physicists says that work on developing a future muon collider could allow the US to regain the “energy frontier”, as Michael Allen reveals
