Nuclear fission reactors struggle with two key problems: poor fuel utilization and complicated radioactive waste handling. To ...

In the case of lead-208—the heaviest stable isotope known so far—a team of researchers led by physicist Jack Henderson ...

For the first time, scientists have acquired direct evidence of rare, pulsing pear-shaped structures within atomic nuclei of ...

There are some potentially valid criticism about the Nuclear Salt Water Rocket (NSWR). The criticisms highlight real physical ...

The SNS offers unprecedented research opportunities due to its intensely bright neutrons and world-class instruments. EQ-SANS is one of 19 instruments available at SNS for users such as Ünnep and ...

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic nuclei – the center part of atoms, which make up all matter – were more ...

The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...

Heavy water can help keep such a chain reaction going. As each uranium atom breaks apart, it shoots out neutrons that can go on to split other atoms. But the neutrons are much more likely to ...

In the past three years, astronomers have discovered a mysterious new type of radio source. We call these long-period transients. An international team of astronomers led by scientists from the ...

The strong force binds the fundamental particles known as quarks together to form particles such as the protons and neutrons of the atomic nucleus. Protons and neutrons are both composites of ...
