Demonstration of RAF jackal drone firing missiles.

This footage shows a demonstration where a new RAF ‘Jackal’ drone fires missile at a target. The missile can be seen launching out the new drone as it flies above the ground.

Space weapons have been launched to intercept satellites.

US believes Russia’s recently launched satellite can inspect and attack other satellites in low Earth orbit.

Yale researchers are using chemical “chameleons” to sneak up on drug-resistant brain tumors.

A Yale Cancer Center team has synthesized a compound, KL-50, that they say selectively targets drug-resistant glioblastomas while leaving healthy tissue alone.

Yale scientists say KL-50, their lead “chameleon” compound, effectively targets tumors without harming healthy surrounding tissue.

The surge of treatment-resistant microbes is happening in real time in health care settings across the U.S. Knowing how to deal with it is essential.

Images from the James Webb Space Telescope and the Chandra X-ray Observatory have been combined to reveal how the Crab Nebula’s neutron star is changing.

Quantum field theory reveals potential flaws in models predicting numerous primordial black holes, suggesting fewer exist, which may impact theories of dark matter and the universe’s structure.

Researchers have applied the well-understood and highly verified quantum field theory, usually applied to the study of the very small, to a new target, the early universe. Their exploration led to the conclusion that there ought to be far fewer miniature black holes than most models suggest, though observations to confirm this should soon be possible. The specific kind of black hole in question could be a contender for dark matter.

The study, which was published recently in Physical Review Letters, was conducted by researchers at the Research Center for the Early Universe (RESCEU) and Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI) at the University of Tokyo.

NGC 2005, a globular cluster in the Large Magellanic Cloud, serves as a crucial piece of evidence supporting the theory of galaxies evolving through mergers.

This mesmerizing image from the Hubble Space Telescope features the globular cluster NGC 2005. While it is not unusual in and of itself, it is a peculiarity in relation to its surroundings.

NGC 2005 is located about 750 light-years from the heart of the Large Magellanic Cloud (LMC), which is the Milky Way ’s largest satellite galaxy and which itself lies about 162,000 light-years from Earth. Globular clusters are densely packed clusters that can constitute tens of thousands or millions of stars. Their density means that they are tightly gravitationally bound and are therefore very stable. This stability contributes to their longevity: globular clusters can be billions of years old, and as such often comprise very old stars.

New astrophysical research highlights a significant cosmic event two million years ago when the solar system passed through a dense interstellar cloud. This possibly altered Earth’s climate by exposing it to enhanced cosmic radiation, supported by increased isotopes found in geological records.

Earth was a very different place around two million years ago, with our early human ancestors living alongside saber-toothed tigers, mastodons, and enormous rodents. And, depending on where they were, they may have been cold: Earth had fallen into a deep freeze, with multiple ice ages coming and going until about 12,000 years ago. Scientists theorize that ice ages occur for a number of reasons, including the planet’s tilt and rotation, shifting plate tectonics, volcanic eruptions, and carbon dioxide levels in the atmosphere.

But what if drastic changes like these are not only a result of Earth’s environment, but also the sun’s location in the galaxy?
