Our genes shape our gut bacteria

Researchers discovered that most bacteria in the gut microbiome are heritable after looking at more than 16,000 gut microbiome profiles collected over 14 years from a long-studied population of baboons in Kenya's Amboseli National Park.

Meet the open-source software powering NASA's Ingenuity Mars Helicopter

When NASA's Ingenuity Mars Helicopter hovered above the Red Planet April 19 on its maiden voyage, the moment was hailed as the first instance of powered, controlled flight on another planet. Figuring out how to fly on Mars, where the air is thin but gravity is about a third of that on Earth, took years of work. Along with the challenge of developing a craft that was up to the task, the mission...

The pressure is off and high temperature superconductivity remains

In a critical next step toward room-temperature superconductivity at ambient pressure, Paul Chu, Founding Director and Chief Scientist at the Texas Center for Superconductivity at the University of Houston (TcSUH), Liangzi Deng, research assistant professor of physics at TcSUH, and their colleagues at TcSUH conceived and developed a pressure-quench (PQ) technique that retains the pressure-enhanced...

Unlocking radiation-free quantum technology with graphene

"Heavy fermions" are an appealing theoretical way to produce quantum entangled phenomena, but until recently have been observed mostly in dangerously radioactive compounds. A new paper in Physical Review Letters has shown it is possible to make heavy fermions in subtly modified graphene, which is much cheaper and safer.

First study of nickelate's magnetism finds a strong kinship with cuprate superconductors

Ever since the 1986 discovery that copper oxide materials, or cuprates, could carry electrical current with no loss at unexpectedly high temperatures, scientists have been looking for other unconventional superconductors that could operate even closer to room temperature. This would allow for a host of everyday applications that could transform society by making energy transmission more efficient,...

The outsized impacts of rudeness in the workplace

Rude behavior is a common form of insensitive and disrespectful conduct that harms employees' performance in the workplace. In a new study, researchers examined the impact of rude behavior on how individuals make critical decisions. The study found that in certain situations, these behaviors can have deadly consequences.

Astronomers map interstellar dust grains in Milky Way

Between the stars in our Milky Way, vast amounts of tiny dust grains are floating aimlessly around. They form the building blocks of new stars and planets. But we still don't know what elements exactly are available to form planets like Earth. A research team at SRON led by Elisa Costantini has now matched observations from X-ray telescopes with data from synchrotron facilities to create a map of...
