Scientists have achieved a breakthrough in analog computing, developing a programmable electronic circuit that harnesses the properties of high-frequency electromagnetic waves to perform complex parallel processing at light-speed.

The discovery points to a new era of computing that operates far beyond the limits of conventional digital electronics, using less energy, while performing massive calculations.

The study, “Programmable circuits for analog matrix computations,” has been published in Nature Communications.

The research was led by Dr...

In the hunt for extraterrestrial life, we usually look for planets orbiting sun-like stars and icy moons. But there is another possible candidate—planets circling white dwarfs, the hot, dense remnants of dead stars.

A white dwarf is what is left when a star like our sun runs out of fuel and sheds its outer layers...

A research team co-led by the Institute for Bioengineering of Catalonia (IBEC) and West China Hospital Sichuan University (WCHSU), working with partners in the UK, has demonstrated a nanotechnology strategy that reverses Alzheimer’s disease in mice.

Unlike traditional nanomedici...

Could black holes help explain high-energy cosmic radiation?

Scientists may have finally uncovered the mystery behind ultra-high-energy cosmic rays — the most powerful particles known in the universe. A team from NTNU suggests that colossal winds from supermassive black holes could be accelerating these particles to unimaginable speeds. These winds, moving at half the speed of light, might not only shape entire galaxies but also fling atomic nuclei across the cosmos with incredible energy.

The universe is full of different types of radiation and particles that can be observed here on Earth. This includes photons across the entire range of the electromagnetic spectrum, from the lowest radio frequencies all the way to the highest-energy gamma rays...
