Physicists develop new tool that could improve cancer research

University of Arkansas physicists have developed a new way for quantifying data from microscopic observations that could help scientists better study how cancer cells respond to treatment, among other benefits. The research, recently published in the journal PLOS ONE, was carried out by Shenghang Jiang, at the time a Fayetteville High School student who was working with Department of Physics assistant professor Yong Wang.

First neutron beam produced: A great milestone for China Spallation Neutron Source

Researchers produced a neutron beam at the China Spallation Neutron Source (CSNS) for the first time on August 28. The achievement is a milestone for the CSNS project as it marks the completion of main construction and the start of the test operation phase. The national CSNS facility, located in Dongguan, Guangdong Province, should be fully completed and open to domestic and international users by 2018, as scheduled.

Particle physicists on a quest for 'new physics'

After five years of work, EPFL's physicists, together with some 800 international researchers involved in the CERN's LHCb project, have just taken an important step by building a new detector—a scintillating fiber tracker dubbed SciFi—to harvest more data from the collider.

Unique study tests fundamental laws of physics

A study that will ‘test our understanding of how the Universe works, particularly outside the relatively narrow confines of our planet’ is being undertaken by an international team of researchers.

Solubility study could impact energy, biology, environment

Chemical engineers have used the most realistic computer model yet devised to simulate the precise atomic and molecular interactions that come into play when water mixes with alkanes, a family of hydrocarbons that includes methane, propane and other refined products.

President Trump Welcomes Home Record-breaking NASA Astronaut Peggy Whitson

NASA astronauts Peggy Whitson and Jack Fischer received a special welcome as they were flying home to Houston Sunday evening. President Donald Trump spoke by phone with Whitson and Fischer on a NASA plane following Whitson’s record-breaking mission to the International Space Station.

Equation reveals the characteristics of quantum chaos

Researchers have now succeeded in formulating a mathematical result that provides an exact answer to the question of how chaos actually behaves. The researchers have analyzed chaotic states at the atomic level.

New spectrometers increase efficiency of X-ray analyses substantially

So-called Fresnel zone plate spectrometers offer new and more efficient ways of conducting experiments using soft X-rays. In a study published in the journal Optics Express, scientists have presented the design for a reflection zone plate which simplifies the extremely complicated measurements on chemically and biologically relevant systems that have hitherto been difficult to conduct.

Three International Space Station Crewmates Safely Return to Earth

NASA astronaut Peggy Whitson, who set multiple U.S. space records during her mission aboard the International Space Station, along with crewmates Jack Fischer of NASA and Commander Fyodor Yurchikhin of Roscosmos, safely landed on Earth at 9:21 p.m. EDT Saturday (7:21 a.m. Kazakhstan time, Sunday, Sept. 3), southeast of the remote town of Dzhezkazga

NASA Statement on Nomination for Agency Administrator

The following is a statement from acting NASA Administrator Robert Lightfoot on Friday’s announcement of the intended nomination by President Donald Trump of U.S. Rep. Jim Bridenstine to serve as the 13th NASA administrator:
