Physicists Have Observed a Strange New Kind of Transition in Electronic Crystals

by

As basic science teaches us, changes in temperature can result in phase transitions in materials – like when water solidifies as ice in the freezing cold. However, in some cases the temperature that triggers the change is different depending on whether the material is cooling down or warming up. This is known as a hysteresis … Read more

U.S. prosecutors said an MIT scientist hid his China ties. Here’s why their case collapsed | Science

by

For the past year, the U.S. government had argued that Massachusetts Institute of Technology (MIT) engineering professor Gang Chen broke the law by failing to disclose his ties to China when applying for a grant from the Department of Energy (DOE). But last week, prosecutors abruptly reversed course and dropped all charges against him, telling … Read more

Physicists Observe Incredible ‘Quantum Tornados’ Formed From Ultra-Cold Atoms

by

Scientists have observed a stunning demonstration of classic physics giving way to quantum behavior, manipulating a fluid of ultra-cold sodium atoms into a distinct tornado-like formation.   Particles behave differently on the quantum level, in part because at this point their interactions with each other hold more power over them than the energy from their movement. … Read more

MIT Scientists Design a ‘Flying Saucer’ That Could Float Across The Moon

by

Researchers have imagined a lightweight, flying saucer-style rover that can float across the surface of the Moon and other airless planetary surfaces such as asteroids. The ‘flying saucer’ would be powered by the electric field that builds up due to direct exposure to the Sun and its surrounding plasma. In the absence of an atmosphere, this … Read more
