When laser beams meet plasma: New data addresses gap in fusion research

DECEMBER 2, 2019 by University of Rochester New research from the University of Rochester will enhance the accuracy of computer models used in simulations of laser-driven implosions. The research, published in the journal Nature Physics, addresses one of the challenges in scientists’ longstanding quest to achieve fusion. In laser-driven inertial confinement fusion (ICF) experiments, such as the experiments conducted at […]

Helping machines perceive some laws of physics

Model registers “surprise” when objects in a scene do something unexpected, which could be used to build smarter AI. Rob Matheson | MIT News OfficeDecember 2, 2019 Humans have an early understanding of the laws of physical reality. Infants, for instance, hold expectations for how objects should move and interact with each other, and will […]

Shaking head to get rid of water in ears could cause brain damage, physicists find

NOVEMBER 24, 2019 by American Physical Society Trapped water in the ear canal can cause infection and even damage, but it turns out that one of the most common methods people use to get rid of water in their ears can also cause complications. Researchers at Cornell University and Virginia Tech show shaking the head to […]

Blowing bubbles: Scientist confirms novel way to launch and drive current in fusion plasmas

NOVEMBER 18, 2019 by Raphael Rosen, Princeton Plasma Physics Laboratory An obstacle to generating fusion reactions inside facilities called tokamaks is that producing the current in plasma that helps create confining magnetic fields happens in pulses. Such pulses, generated by an electromagnet that runs down the center of the tokamak, would make the steady-state creation of […]

Physicists determine dripline for fluorine and neon isotopes

NOVEMBER 22, 2019 An international team of physicists with the BigRIPS experiment taking place at the RIKEN Radioactive Isotope Beam Factory in Japan has determined the dripline for fluorine and neon isotopes. In their paper published in the journal Physical Review Letters, the researchers describe how they found the driplines and where their research is headed […]

Chemistry in the turbulent interstellar medium

NOVEMBER 22, 2019 by Harvard-Smithsonian Center for Astrophysics Over 200 molecules have been discovered in space, some (like Buckminsterfullerene) very complex with carbon atoms. Besides being intrinsically interesting, these molecules radiate away heat, helping giant clouds of interstellar material cool and contract to form new stars. Moreover, astronomers use the radiation from these molecules to study […]

New twist in quest to develop understanding of time crystalline behavior

NOVEMBER 21, 2019 by University of Exeter The quest to develop the understanding for time crystalline behaviour in quantum systems has taken a new, exciting twist. Physics experts from the Universities of Exeter, Iceland, and ITMO University in St. Petersburg, have revealed that the existence of genuine time crystals for closed quantum systems is possible. Different […]

Protein imaging at the speed of life

With this capability, scientists can watch how proteins do their jobs properly—or how their shape-changing goes awry, causing disease. NOVEMBER 18, 2019 by University of Wisconsin – Milwaukee To study the swiftness of biology—the protein chemistry behind every life function—scientists need to see molecules changing and interacting in unimaginably rapid time increments—trillionths of a second or […]

From a cloud of cold and a spark, researchers create and stabilize pure polymeric nitrogen for the first time

NOVEMBER 14, 2019 by Drexel University Scientists have long theorized that the energy stored in the atomic bonds of nitrogen could one day be a source of clean energy. But coaxing the nitrogen atoms into linking up has been a daunting task. Researchers at Drexel University’s C&J Nyheim Plasma Institute have finally proven that it’s experimentally […]

Physicists irreversibly split photons by freezing them in a Bose-Einstein condensate

NOVEMBER 14, 2019 by University of Bonn Light can be directed in different directions, usually also back the same way. Physicists from the University of Bonn and the University of Cologne have, however, succeeded in creating a new one-way street for light. They cool photons down to a Bose-Einstein condensate, which causes the light to collect […]
