Physicists force dark matter

This image of Centaurus A, one of Earth's closest active galaxies, combines data from observations in multiple frequency ranges. Credit: ESO / WFI (optical), MPIfR / ESO / APEX / A. Weiss et al. (Submillimeter), NASA / CXC / CfA / R. Kraft et al. (Roentgen) Researchers from Russia, Finland and the US have limited the theoretical model of dark …

Physicists discover surprisingly complex states resulting from simple synchronized networks

Firefly glow in unison. Picture credits: Radim Schreiber Fireflies, heart cells, clocks and power grids do this – they can synchronize spontaneously and emit signals at the same time. For centuries scientists have been stunned by this self-organizing behavior and have developed theories and experiments that make up the science of synchronization. Despite progress in the field, mysteries remain, especially …

Physicists set world record in plasma plasma acceleration with laser drill

Enlarge / Various drivers can be used with Wakefield acceleration. In the laser-controlled case (top), a strong laser pulse is emitted into a preformed plasma. In the proton-driven scenario (below), a high-energy proton packet is sent into a gas. Particle accelerators can accelerate subatomic particles to near the speed of light. The disadvantage is that this requires miles of tunnels, …

Physicists have just solved a 35-year-old puzzle in atomic nuclei

Here is a mysterious truth that scientists have known since 1983: Protons and neutrons behave differently when they are inside an atom than floating freely in space. In particular, the subatomic particles that make up these protons and neutrons, called quarks, slow down massively when bound to an atomic nucleus. Physicists really did not like that because neutrons are neutrons …

Finally, the physicists learn why the grapes ignite in the microwave

A fire just waiting. (Credit: Kaiskynet Studio / Shutterstock) Consider the modest grape. Small, spherical, with a pleasantly firm skin that leaves a sweet suction on the tongue. Hardly a fruit against which you have to defend yourself. Put a gently touching couple in the microwave, and the harmless fruit turns into a true firecracker. Within a few seconds, microwave-filled …
