Shock waves might offer the jolt needed to reach Mars

Applying shockwaves can improve conditions for fluid mixing in supersonic combustion engines, paving the way for flights at speeds five times faster than the speed of sound.

Spin, spin, spin: researchers enhance electron spin longevity

The electron is an elementary particle, a building block on which other systems evolve. With specific properties such as spin, or angular momentum, that can be manipulated to carry information, electrons are primed to advance modern information technology. An international collaboration of researchers has now developed a way to extend and stabilize the lifetime of the electron's spin to more effectively carry information.

Nanoparticles tailored for special applications synthesized

'Core-shell' clusters pave the way for new efficient nanomaterials that make catalysts, magnetic and laser sensors or measuring devices for detecting electromagnetic radiation more efficient.

Long-standing tension in the Standard Model addressed

The best-known particle in the lepton family is the electron, a key building block of matter and central to our understanding of electricity. But the electron is not an only child. It has two heavier siblings, the muon and the tau lepton, and together they are known as the three lepton flavors. According to the Standard Model of particle physics, the only difference between the siblings should be their mass: the muon is about 200 times heavier than the electron, and the tau-lepton is about 17 times heavier than the muon.

Team proposes new integrated power-exhaust control solution for fusion reactor steady-state operation

The Experimental Advanced Superconducting Tokamak (EAST) team has proposed a new integrated control solution to tackle key problems in divertor power exhaust for the steady state operation of tokamak fusion reactor.

Cosmic tango between the very small and the very large

While Einstein's theory of general relativity can explain a large array of fascinating astrophysical and cosmological phenomena, some aspects of the properties of the universe at the largest-scales remain a mystery. A new study using loop quantum cosmology—a theory that uses quantum mechanics to extend gravitational physics beyond Einstein's theory of general relativity—accounts for two major mysteries. While the differences in the theories occur at the tiniest of scales—much smaller than even a proton—they have consequences at the largest of accessible scales in the universe.

Mars 2020 Launch: NASA's Perseverance Rover Ready for Journey to the Red Planet

The mission will not only search for evidence of ancient martian life, but also test a method for plucking usable oxygen straight from Mars’ thin air. Oh, it also has a helicopter.

Scientists make quantum technology smaller

A way of shrinking the devices used in quantum sensing systems has now been developed.

Nobel prize-winning work is concentrated in minority of scientific fields

From 1995 to 2017, work that was awarded a Nobel Prize in Medicine, Physics, or Chemistry clustered in just a few scientific disciplines.

What Would Happen if You Fell Into a Black Hole?

If you plummeted into a black hole, your body would be ripped apart in a process called “spaghettification.”
