Making the physics of glass more transparent

For centuries, humans have made use of glass in their art, tools, and technology. Despite the ubiquity of this material, however, many of its microscopic properties are not well understood, and it continues to defy conventional physical description.

Quantum cosmology with final states can explain the accelerated expansion of the universe

Teleology is the idea that some processes in nature are directed toward a goal or an end. Today, it is commonly asserted that teleology is a remnant of antiquated ways of thinking about causation, and that it is not compatible with modern science, because it is fundamentally untestable.

In the search for life on exoplanets, finding nothing is something too

What if humanity’s search for life on other planets returns no hits? A team of researchers led by Dr. Daniel Angerhausen, a Physicist in Professor Sascha Quanz’s Exoplanets and Habitability Group at ETH Zurich and a SETI Institute affiliate, tackled this question by considering what could be learned about life in the universe if future surveys detect no signs of life on other planets.

The International Space Station is too clean—what does that tell us about how to co-exist with bugs on Earth?

One of the cleanest places beyond Earth may be making its residents ill. Astronauts aboard the International Space Station (ISS) have had rashes, allergies and the odd infection, and scientists now believe the station’s environment is too clean. Researchers recently concluded that the ISS is so sterile it may be damaging astronauts’ health and have even suggested it might be time to make the station deliberately “dirtier.”

Hubble helps determine Uranus’ rotation rate with unprecedented precision

An international team of astronomers using the NASA/ESA Hubble Space Telescope have made new measurements of Uranus’ interior rotation rate with a novel technique, achieving a level of accuracy 1,000 times greater than previous estimates. By analyzing more than a decade of Hubble observations of Uranus’ aurorae, researchers have refined the planet’s rotation period and established a crucial new reference point for future planetary research.

Physicists uncover a metallic altermagnet with d-wave spin splitting at room temperature

For many years, physics studies focused on two main types of magnetism, namely ferromagnetism and antiferromagnetism. The first type entails the alignment of electron spins in the same direction, while the latter entails the alignment of electron spins in alternating, opposite directions.

High-intensity shock tube reveals high-speed interface flow mechanism

Research teams have established a theoretical method for designing smooth curved wall surfaces with variable cross-section shock tubes, and developed an integrated, high-intensity multifunctional shock tube device. Led by Prof. Luo Xisheng and Prof. Si Ting from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), the study was published in Review of Scientific Instruments.

Blue Origin plans an all-female space flight—but astronaut memoirs reveal the cost of being exceptional

For the first time since Russian cosmonaut Valentina Tereshkova’s solo flight in 1963, a spacecraft will enter orbit with only women aboard. Blue Origin’s all-female space flight crew, which includes popstar Katy Perry, is set to take off this spring.
