A Kansas City startup wants to make roads smart by replacing asphalt with high-tech slabs of concrete. But are they better, than normal roads?

The mind boggling discovery that time crystals were real happened just last year, and already scientists are demonstrating possible uses for them, including their potential to revolutionize quantum computer systems.

The platform’s unique high-precision computing capabilities are designed for the growing number of applications that combine high-performance computing with AI.

A new finding from the UVA School of Medicine suggests that fatty liver disease and other effects of aging may be the result of our cells’ nuclei getting wrinkly.

Virgin Galactic is celebrating a successful second test flight of SpaceShipTwo, the rocket-powered passenger spacecraft that may someday take tourists to the edge of space. Today’s test took the VSS Unity, the second craft built in this class, up to 114,500 feet and Mach 1.9, or nearly 1,300 miles per hour.

Unity’s first powered flight was less than two months ago, which was itself the first powered flight Virgin Galactic had attempted since the fatal breakup of the company’s previous SpaceShipTwo-class spacecraft, Enterprise, in 2014.

Much has been redone since then but the basics of the Virgin Galactic flight style are the same. A relatively traditional jet-powered plane, a WhiteKnightTwo class plane (in this case the VMS Eve), carries the SpaceShipTwo craft (Unity) up to somewhere around 45,000 feet. There the latter detaches and fires up its rocket engine, accelerating to high speed and high altitude, after which it glides to the surface and lands more or less like any other plane.

Robots provide free labor that can be used to construct meaningful places for us to live.

People with disabilities are underrepresented in STEM.

An artificial intelligence system accurately detected 95 percent of dangerous skin lesions in more than 100,000 images, compared to 86.6 percent by human dermatologists.

Using a pioneering method, researchers from the Astronomy and Astrophysics Group of the UPC and the Canary Islands Institute of Astrophysics (IAC) have found a neutron star of about 2.3 solar masses—one of the most massive ever detected. The study was published on the 23rd of May in the Astrophysical Journal and opens a new path of knowledge in many fields of astrophysics and nuclear physics.

Neutron stars (often called pulsars) are stellar remnants that have reached the end of their evolutionary life: they result from the death of a star of between 10 and 30 solar masses. Despite their small size (about 20 kilometres in diameter), neutron stars have more mass than the sun, so they are extremely dense.

Researchers from the Universitat Politècnica de Catalunya (UPC) and the Canary Islands Institute of Astrophysics (IAC) used an innovative method to measure the mass of one of the heaviest neutron stars known to date. Discovered in 2011 and called PSR J2215+5135, with about 2.3 solar masses it is one of the most massive of the more than 2,000 neutron stars known to date. Although a study published in 2011 reported evidence of a neutron star with 2.4 solar masses, the most massive neutron stars that had previously achieved a consensus among scientists, reported in 2010 and 2013, have 2 solar masses.
