Research reveals hidden damage caused by heat

Heat affects not only our well-being, but also the performance and lifespan of systems and devices. However, it is often difficult to measure these effects accurately.

Our understanding of lightning has been driven by fear and shaped by curiosity

Playwright Tom Stoppard, in “Rosencrantz and Guildenstern are Dead,” provides one of the best definitions of science: “The scientific approach to the examination of phenomena is a defense against the pure emotion of fear.”

Physicists devise an idea for lasers that shoot beams of neutrinos

At any given moment, trillions of particles called neutrinos are streaming through our bodies and every material in our surroundings, without noticeable effect. Smaller than electrons and lighter than photons, these ghostly entities are the most abundant particles with mass in the universe.

Shedding light on insulators: How light pulses unfreeze electrons

Metal oxides are abundant in nature and central to technologies such as photocatalysis and photovoltaics. Yet, many suffer from poor electrical conduction, caused by strong repulsion between electrons in neighboring metal atoms.

50 years ago, NASA sent two spacecraft to search for life on Mars. The missions’ findings are still discussed today

Finding life beyond Earth would be a major scientific discovery with significant implications for all areas of science and human thought. Yet, only one direct search for extraterrestrial life has ever been conducted.

Is space worth the cost? Accounting experts say its value can’t be found in spreadsheets

Since the early days of human space exploration, the endeavor has been haunted by a very good question: why spend so much on space when there are so many urgent problems here on Earth?

The Hofstadter butterfly: Twisted bilayer graphene reveals two distinct strongly interacting topological phases

Magic-angle twisted bilayer graphene (MATBG) is a material created by stacking two sheets of graphene onto each other, with a small twist angle of about 1.1°. At this “magic angle,” electrons move very slowly, which can lead to the emergence of highly correlated electron states.

Ultra-wideband radio observations unravel polarization mystery of millisecond pulsar

Within our Milky Way galaxy, in the direction of the constellation Vulpecula, a cosmic “lighthouse” named PSR B1937+21 spins at an astonishing rate of 642 revolutions per second. It emits electromagnetic pulses that rival the precision of atomic clocks.

The Murchison Widefield Array just doubled in size—what could it find now?

Radio astronomy took another step forward recently, with the completion of Phase III of the Murchison Widefield Array (MWA) in Western Australia. We’ve reported before on how the MWA has investigated everything from SETI signals to the light from the earliest stars. With this upgrade, the MWA will continue to operate with much needed improvements […]

Plasma propulsion system could help remove space debris without contact

Space has a trash problem, with defunct satellites, rockets, and smaller broken bits orbiting Earth at high speeds. The amount of space junk is only increasing, raising the risk of collision with active satellites and spacecraft, according to Kazunori Takahashi, associate professor in the Graduate School of Engineering at Tohoku University in Japan. Takahashi may […]

INTEGRAL observes exceptionally bright X-ray flares from Cygnus X-1

Using ESA’s INTEGRAL spacecraft, astronomers have detected exceptionally bright X-ray flares from the Cygnus X-1 X-ray binary system. This is the first time that such strong flaring activity has been observed in this system although it has been monitored for decades. The new findings were detailed in a paper published August 28 on the pre-print […]
