Lawrence Livermore National Laboratory (LLNL) researchers have refined the measurement of the gamma (γ)-to-neutron branching ratio in deuterium-tritium (D-T) fusion reactions. This reaction is a ...

The number-one job of a marketer is to invest budget wisely to drive sales. That inherently requires accurately measuring the performance of that spending. Yet most advertisers still rely on flawed ...

For decades scientists have tried to find a way to measure the mass of the lightest matter particle known to exist. Three new approaches now have a chance to succeed. In 1980, Hamish Robertson was a ...

Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

When satellites take pictures of Earth at night, how much of the light that they see comes from streetlights? A team of scientists from Germany, the USA, and Ireland have answered this question for ...

Last week over in Twitter-land, Philip Ball asked an interesting question: I’ve written a fair bit about historical science, and read more than I’ve written, so this question stuck with me, and seems ...

Physicists have just dropped a new precise measurement for gravity. The newly published value for the strength of gravity, known as “G” or “Big G”, is significantly smaller than some previous ...
