(PhysOrg.com) -- “Axionlike particles are interesting because they come up regularly when scientists study string theory. By looking at their properties, you hope to learn about string theory, or some other unified theory ...
You might find it hard to believe that dust clouds from the African Sahara can travel thousands of miles across the Atlantic Ocean, but it does every year and in large quantities. In a recent study, Joseph Prospero, professor ...
