Newly discovered material conducts heat nearly 3x faster than any metal
Data center servers, powerful smartphones, and your computer's motherboard have one thing in common. When these devices get too hot, their performance takes a hit, and we can't have that. That's why copper is used to manufacture them: this metal has high thermal conductivity, which means it can efficiently carry heat and dissipate it across its surface.

Germany orders reusable hypersonic HYTEV from POLARIS Raumflugzeuge
Germany's BAAINBw has commissioned Bremen-based POLARIS Raumflugzeuge to build HYTEV, a two-stage, horizontally launched, fully reusable hypersonic research aircraft in fighter-jet size. The concept, developed in 2024–25, targets flight readiness by late 2027.
HYTEV's main stage runs two turbofans with an Aerospike rocket; the upper stage is rocket-powered. It can lift up to about 1,000 kg to space and may also serve as a small-satellite carrier or reconnaissance platform in and beyond the atmosphere, at Mach 5+.
