Black Holes and Dark Matter…
Artist’s impression of a microlensing event caused by a black hole observed from Earth toward the Large Magellanic Cloud. The light of a background star located in the LMC is bent by a putative primordial black hole (lens) in the Galactic halo and magnified when observed from the Earth. Microlensing causes very characteristic variation ofContinue reading “Black Holes and Dark Matter…”
Dolphins and Mercury…
Scientists have found elevated mercury levels in dolphins throughout the Southeast since 2007. Sources: Bryan, Damseaux, Griffin, Stavros, Woshner. Credit: N. Hanacek/NIST Topics: Biology, Chemistry, Civilization, Environment In a study with potential implications for the oceans and human health, scientists reported elevated mercury levels in dolphins in the U.S. Southeast, with the greatest levels found in dolphins in Florida’s St. JosephContinue reading “Dolphins and Mercury…”

AP Photo/Andres Kudacki Topics: Applied Physics, Diversity in Science, Physics, Physiology “B-boys and B-girls wield physics to pull off gravity-defying dance moves.” Okay, “gravity-defying” is a bit of hyperbole. Break dancing, as the article alludes, started in New York, and the movements can be found in martial arts like Brazilian Capoeira. It’s more centrifugal forceContinue reading “B Boys & Girls, Physics & Olympics…”
