Fluid forces on particulate beds can be used to model erosion processes, filtration systems, and industrial particulate ...
The strength of gravity is different on every body in the solar system. Whether it's the crushing weight of Jupiter or the ...
Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to belong to one of two categories — bosons or fermions — but researchers have ...
Scientists have discovered that ultraheavy atomic nuclei could explain some of the highest-energy cosmic rays ever observed.
Stardust Solutions says its tiny spheres can reflect the sun’s rays without harming people or the environment. Critics say private companies have no business altering Earth’s atmosphere. An enclosed ...
Eighty years ago, Penn researchers J. Presper Eckert and John Mauchly launched the age of electronic computing by harnessing electrons to solve complex numerical problems with ENIAC, the world's first ...
Swollen supraclavicular lymph nodes may occur as a reaction to infection or due to metastatic cancer. This type of swelling typically occurs just above a person’s collarbone. Swelling in the ...
Swollen lymph nodes in the groin, called inguinal lymph nodes, are usually caused by a lower body infection, such as sexually transmitted infections (STIs), fungal infections, cellulitis, or urinary ...
Nanoparticles are particles that exist on a nanometre scale (i.e., below 100 nm in at least one dimension). They can possess physical properties such as uniformity, conductance or special optical ...
