In this interview, News Medical talks to Patrick D. Sinko about the role of particle size, dose, and confinement parameters in advancing drug absorption modeling. Could you explain what a boundary ...

For the past half century or so, a theory known by the understated name of the Standard Model has dominated the field of particle physics. This theory provides us with a detailed description of the 17 ...

During the Artemis II mission launched Wednesday, NASA will test out a pair of new solar radiation forecasts, developed at ...

After a decade-long analysis, a collaboration of physicists has made the most precise measurement of the mass of a key particle – and it may unravel physics as we know it. The new measurement differs ...

In the mid-1930s, physicists thought they knew all the subatomic particles of nature – the proton, neutron, and electron of the atom. However, in 1936 the muon was discovered – a new particle having ...

Scientists have taken a major step toward solving a long-standing mystery in particle physics, by finding no sign of the particle many hoped would explain it. Might two bent crystals pave the way to ...
