New York Times: By measuring the ratio of cosmic alpha particles to cosmic antialpha particles, the Alpha Magnetic Spectrometer could help to answer one of the most puzzling and fundamental questions in physics: Why is there more matter than antimatter in the universe? In February, if all goes to schedule, the space shuttle Endeavour will carry the AMS on its final flight to the International Space Station, where the instrument will begin its experimental run. Dennis Overbye of the New York Times profiles the experiment and its inventor, MIT’s Sam Ting.
The finding that the Saturnian moon may host layers of icy slush instead of a global ocean could change how planetary scientists think about other icy moons as well.
Modeling the shapes of tree branches, neurons, and blood vessels is a thorny problem, but researchers have just discovered that much of the math has already been done.
