We summarize the week's scientific breakthroughs every Thursday.
- Tech
50 years ago, a Japanese scientist dreamed up a rocket-propelled train
50 years ago, a Japanese engineer tried rocket boosters on a train. Today, high-speed trains propelled by superconducting magnets are being tested.
- Physics
Einstein’s general relativity reigns supreme, even on a galactic scale
Scientists have made the most precise test of Einstein’s theory of gravity at great distances.
- Physics
To combat an expanding universe, aliens could hoard stars
An advanced alien civilization might combat the impact of dark energy by harvesting stars.
- Physics
The Large Hadron Collider is getting an upgrade
Revamping the accelerator’s equipment will increase the rate of proton collisions.
- Astronomy
In 1968, scientists thought they were close to detecting gravity waves
Despite an unverified discovery in 1968, spacetime ripples remained elusive for nearly 50 years.
- Physics
This heavy element has a football-shaped atomic nucleus
Three nobelium isotopes have oblong nuclei, and some sport a ‘bubble’ center.
- Physics
In her short life, mathematician Emmy Noether changed the face of physics
A century after she published a groundbreaking mathematical theory, Emmy Noether gets her due.
- Science & Society
So what do you know about Emmy Noether?
Editor in Chief Nancy Shute discusses physicist Emmy Noether and women being underrepresented in science fields.
- Astronomy
The sun shrinks a teensy bit when it’s feeling active
The radius of the sun gets slightly smaller during periods of high solar activity, researchers say.
- Tech
A new 3-D printer builds temporary electronics on your skin
A new 3-D printer that tracks and compensates for your slightest twitch can precisely print simple electronic devices onto your skin.
- Particle Physics
If real, dark fusion could help demystify this physics puzzle
Fusing dark matter particles might explain why galaxy cores have evenly distributed dark matter.
- Particle Physics
Mysterious neutrino surplus hints at the existence of new particles
Neutrinos show up in greater numbers than expected in an experiment, possibly bolstering the idea of a fourth type of the particle.
