A research team succeeded in executing the world’s fastest two-qubit gate (a fundamental arithmetic element essential for quantum computing) using a completely new method of manipulating, with an ultrafast laser, micrometer-spaced atoms cooled to absolute zero temperature. For the past two decade.

Absolute zero is the theoretical lowest temperature on the thermodynamic temperature scale. At this temperature, all atoms of an object are at rest and the object does not emit or absorb energy. The internationally agreed-upon value for this temperature is −273.15 °C (−459.67 °F; 0.00 K).

Rebecca Trager examines an emerging industry that is growing ‘meat’ outside of animals using cell lines cultivated in bioreactors.

Astronomers have long sought the launch sites for some of the highest-energy protons in our galaxy. Now a study using 12 years of data from NASA’s Fermi Gamma-ray Space Telescope confirms that one supernova remnant is just such a place.

Fermi has shown that the shock waves of exploded stars boost particles to speeds comparable to that of light. Called cosmic rays, these particles mostly take the form of protons, but can include atomic nuclei and electrons. Because they all carry an electric charge, their paths become scrambled as they whisk through our galaxy’s magnetic field. Since we can no longer tell which direction they originated from, this masks their birthplace. But when these particles collide with interstellar gas near the supernova remnant, they produce a telltale glow in gamma rays—the highest-energy light there is.

MIT researchers have developed a method for 3D printing materials with tunable mechanical properties, that sense how they are moving and interacting with the environment. The researchers create these sensing structures using just one material and a single run on a 3D printer.

To accomplish this, the researchers began with 3D-printed lattice materials and incorporated networks of air-filled channels into the structure during the printing process. By measuring how the pressure changes within these channels when the structure is squeezed, bent, or stretched, engineers can receive feedback on how the material is moving.

The method opens opportunities for embedding sensors within architected materials, a class of materials whose mechanical properties are programmed through form and composition. Controlling the geometry of features in architected materials alters their mechanical properties, such as stiffness or toughness. For instance, in cellular structures like the lattices the researchers print, a denser network of cells makes a stiffer structure.

The discovery of a super-Earth around the red dwarf Ross 508 is reported by astronomers in Japan. Part of the planet’s elliptical orbit takes it within the star’s habitable zone, where liquid water may exist.

This cabin in the woods is an otherworldly, all-black, geometric structure built to provide cozy refuge even in harsh Finnish winters. It was designed for a California-based CEO who returned home to Finland with her family to be closer to her ancestral land so she could maintain it. The cabin is aptly named Meteorite based.

This cabin in the woods is an otherworldly, all-black, geometric structure built to provide cozy refuge even in harsh Finnish winters. It was designed for a California-based CEO who returned home to Finland with her family to be closer to her ancestral land so she could maintain it. The cabin is aptly named Meteorite based on its unique shape and is set in a clearing surrounded by spruce and birch trees. The cabin is made entirely from cross-laminated timber (CLT) which is a sustainable alternative to other construction materials.

A new study corrects an important error in the 3D mathematical space developed by the Nobel Prize-winning physicist Erwin Schrödinger and others, and used by scientists and industry for more than 100 years to describe how your eye distinguishes one color from another. The research has the potential to boost scientific data visualizations, improve TVs and recalibrate the textile and paint industries.

“The assumed shape of color space requires a paradigm shift,” said Roxana Bujack, a computer scientist with a background in mathematics who creates scientific visualizations at Los Alamos National Laboratory. Bujack is lead author of the paper by a Los Alamos team in the Proceedings of the National Academy of Sciences on the mathematics of color perception.
