International research team unveils the first electrically pumped continuous-wave semiconductor laser designed for seamless integration with silicon.

Scientists from Forschungszentrum Jülich (FZJ), the University of Stuttgart, the Leibniz Institute for High Performance Microelectronics (IHP), and their French partner CEA-Leti have successfully developed the first electrically pumped continuous-wave semiconductor laser made entirely from group IV elements, commonly referred to as the “silicon group” in the periodic table.

This innovative laser is constructed from stacked ultrathin layers of silicon-germanium-tin and germanium-tin. Remarkably, it is the first laser of its type to be directly grown on a silicon wafer, paving the way for advancements in on-chip integrated photonics. The research findings have been published in the prestigious journal Nature Communications.

Stimulating dopamine-producing brain cells wirelessly with gold nanoparticles has proven effective at treating mice with Parkinson’s disease, even reversing a portion of their neurological damage.

Researchers from the National Center for Nanoscience and Technology of China (NCNST) say it’s a significant step forward for using brain simulation to tackle Parkinson’s in humans, a neurodegenerative condition that affects more than 10 million people worldwide.

Deep inside the brains of those with the condition, dopamine-producing neurons take a major hit as insoluable clumps of a protein called alpha-synuclein accumulate, gradually depriving patients of an ability to control their movements.

SpaceX is preparing to launch the seventh Starship flight test. The window for the launch opens at 4 p.m. local time on Monday. The company has confirmed on its website, and X, that it is targeting a potential catch of the Super Heavy booster, if flight parameters allow for it. SpaceX will also try to re-ignite a single Raptor engine in space to demonstrate deorbit capabilities. This flight is the first one, that will feature the new upgraded Starship upper stage!

Window Opens: January 15th at 4PM CST (22:00 UTC)
Window Closes: January 15th at 5PM CST (23:00 UTC)

Snakebites affect 1.8 to 2.7 million people annually, causing around 100,000 deaths and three times as many permanent disabilities, according to the World Health Organization. Victims are predominantly in regions with fragile healthcare systems, such as Africa, Asia, and Latin America. Traditional antivenoms derived from animal plasma come with significant drawbacks: high costs, limited efficacy, and serious side effects.

The diversity of snake venoms further complicates treatment, as current antivenoms often target specific species. However, advances in toxin research and computational tools are now driving a new era in snakebite therapy.

Baker’s team, in collaboration with Timothy Patrick Jenkins from Denmark’s Technical University (DTU), harnessed AI to design proteins that bind to and neutralize three-finger toxins—among the deadliest components of cobra venom. These toxins are notorious for evading the immune system, rendering conventional treatments ineffective.

Researchers find a mathematical key to understanding how AI makes decisions.

UK researchers used special optical tweezers to attain quantum entanglement of molecules that could unlock multiple applications in quantum computing.

After abruptly calling off its first launch attempt in the early hours of Monday morning, Blue Origin notched a historic success with its first orbital rocket.

A team of researchers has discovered a new way to control the magnetic behavior of quantum materials using applied voltages. Specifically, the material lanthanum strontium manganite (LSMO), which is magnetic and metallic at low temperatures but non-magnetic and insulating when relatively warm, can be influenced by voltage.

The work is published in the journal Nano Letters.

Quantum materials like LSMO are materials that possess special properties because of the rules of quantum mechanics. Researchers discovered that applying voltage to LSMO in its magnetic phase causes the material to split into regions with distinct magnetic properties. The magnetic properties of these regions depend on the applied voltage. This is important because normally, magnetic properties don’t respond to voltage.
