Near-infrared light enables wireless power and data transfer for medical implants

A new study from a research team at the Center for Wireless Communications Network and Systems (CWC-NS) at the University of Oulu has introduced an approach using near-infrared (NIR) light beyond light therapy to facilitate simultaneous wireless power transfer and communication to electronic implantable medical devices (IMDs). Previously, the research team demonstrated that NIR light for wireless communication is feasible, and now the team made progress by involving wireless charging capabilities using the same light.

2.8 days to disaster: Why we are running out of time in low earth orbit

A “House of Cards” is a wonderful English phrase that it seems is now primarily associated with a Netflix political drama. However, its original meaning is of a system that is fundamentally unstable. It’s also the term Sarah Thiele, originally a Ph.D. student at the University of British Columbia, and now at Princeton, and her co-authors used to describe our current satellite mega-constellation system in a new paper available in pre-print on arXiv.

XMM-Newton sees comet 3I/ATLAS in X-ray light

The European Space Agency’s X-ray space observatory XMM-Newton observed interstellar comet 3I/ATLAS on 3 December for around 20 hours. During that time, the comet was about 282–285 million km from the spacecraft.

NASA announces plan to map Milky Way with Roman Space Telescope

NASA’s Nancy Grace Roman Space Telescope team has released detailed plans for a major survey that will reveal our home galaxy, the Milky Way, in unprecedented detail. In one month of observations spread across two years, the survey will unveil tens of billions of stars and explore previously uncharted structures.

Radio observations find nothing at Omega Centauri’s heart

Omega Centauri dominates the southern sky as the Milky Way’s largest and brightest globular cluster, a dense sphere containing roughly 10 million stars. Earlier this year, astronomers found evidence that an intermediate mass black hole hides within the cluster’s core, revealed by seven stars moving far too quickly to remain bound unless something massive holds them gravitationally. Now, researchers have searched for the black hole itself using radio telescopes, and their discovery is what they didn’t find.

AI helps solve decades-old maze in frustrated magnet physics

By partnering with artificial intelligence (AI), a researcher at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory has solved a long-standing physics problem and uncovered the mathematical trickery that underlies the generalization of recently discovered, extremely surprising new states of matter. The work exemplifies the paradigm shift that is taking place in research, as scientists learn to see AI as a valuable asset in advancing knowledge and discovery.

Hubble catches another glimpse of 3I/ATLAS

On July 1st, 2025, the third interstellar object (ISO) ever detected was seen making its way through our solar system. Shortly after being alerted by automated detection systems, astronomers at the European Space Agency (ESA) began using observatories in Hawaii, Chile, and Australia to get a better look at the interstellar interloper. Since then, 3I/ATLAS has been observed by multiple space observatories, including the venerable NASA/ESA Hubble Space Telescope. On Nov. 30th, Hubble viewed the ISO again, which is about to make its closest approach to Earth.
