Tucked away in a star-forming region in the Taurus constellation, a pair of circling stars are displaying some unexpected differences in the circumstellar disks of dust and gas that surround them. A new study led by researchers at Lowell Observatory, combining data from the Atacama Large Millimeter/submillimeter Array (ALMA) and Keck Observatory, has unveiled intriguing findings about planet formation in this binary star system, known as DF Tau, along with other systems in this region. The work is published in The Astronomical Journal.

In a study published in the Astrophysical Journal, a team of researchers led by Kristen McQuinn, a scientist at the Space Telescope Science Institute and an associate professor in the Department of Physics and Astronomy at the Rutgers University-New Brunswick School of Arts and Sciences, has reported finding that Leo P, a small galaxy and a distant neighbor of the Milky Way, “reignited,” reactivating during a significant period on the timeline of the universe, producing stars when many other small galaxies didn’t.

Researchers have pioneered the use of parallel computing on graphics cards to simulate acoustic turbulence. This type of simulation, which previously required a supercomputer, can now be performed on a standard personal computer. The discovery will make weather forecasting models more accurate while enabling the use of turbulence theory in various fields of physics, such as astrophysics, to calculate the trajectories and propagation speeds of acoustic waves in the universe. The research was published in Physical Review Letters.

In July 1969, four faculty members traveled from College Park to Kennedy Space Center in Florida to provide last-minute instruction to a noteworthy pupil: an Apollo 11 astronaut about to become one of the first humans to set foot beyond Earth.

Pandora, NASA’s newest exoplanet mission, is one step closer to launch with the completion of the spacecraft bus, which provides the structure, power and other systems that will allow the mission to carry out its work. Pandora’s exoplanet science working group is led by the University of Arizona, and Pandora will be the first mission to have its operations center at the U of A Space Institute.

For the first time ever, scientists have used a technique called “quantum squeezing” to improve the gas sensing performance of devices known as optical frequency comb lasers. These ultra-precise sensors are like fingerprint scanners for molecules of gas. Scientists have used them to spot methane leaks in the air above oil and gas operations and signs of COVID-19 infections in breath samples from humans.

A team of researchers has discovered a new way to control the magnetic behavior of quantum materials using applied voltages. Specifically, the material lanthanum strontium manganite (LSMO), which is magnetic and metallic at low temperatures but non-magnetic and insulating when relatively warm, can be influenced by voltage.

Skoltech researchers have presented a new simple physical model for predicting the hardness of materials based on information about the shear modulus and equations of the state of crystal structures. The model is useful for a wide range of practical applications—all parameters in it can be determined through basic calculations or measured experimentally.

Paper-thin optical lenses simple enough to mass produce like microchips could enable a new generation of compact optical devices. A team with researchers at the University of Tokyo and JSR Corp. fabricated and tested flat lenses called Fresnel zone plates (FZPs), but did so for the first time using only common semiconductor manufacturing equipment, the i-line stepper.

During the last century, biologists have extensively studied Drosophila melanogaster, the common household fruit fly. It’s become one of the most popular model organisms, but not because scientists have been determined to rid kitchen fruit bowls of these summertime nuisances. It’s because their biology is highly conserved and offers invaluable clues about how multicellular organisms all the way to humans function and evolve.
