Researchers help give the kilogram a fundamental equivalent
Much to the consternation of scientists, the cylindrical platinum-iridium artifacts that represent the kilogram (see image above) have been gradually packing on extra weight due to surface contamination. Since that unit of measure is the last to be based on an artifact and not a physical constant of nature -- for instance, a meter is the distance light travels in a vacuum during 1/299,792,458 of a second -- it means that scientists no longer know exactly how much a kilogram is. That makes experiments requiring extreme precision more difficult, so researchers from Mettler Toledo, CERN and the EPFL have been working for the last 15 years on a so-called Watt balance, which works on the principle of electromagnetic force restoration. The team managed to created a "load cell" that's accurate to a 0.3 µg resolution for a 2kg weight, well below the desired level of 1 µg -- meaning the goal of replacing a hunk of metal from 1878 with something more, ahem, solid is within reach by the 2015 target date.
Installing Pre homebrew apps: now even easier
While Palm is busily engaged in a game of domination with Apple to see which one can keep iTunes sync working or broken the longest, the Pre homebrew community hasn't been sitting idle, introducing two new and painless ways to get homemade software up in your handset. The first is a desktop app called WebOS Quick Install that works on Mac, PC, and Linux, allowing installation with just a drag, a drop, and a click. The other is called fileCoaster, enabling users to download and install IPKs right on the phone itself, plus other files too. Two great apps for fans of unofficial softwares and good tidings for a warm future of basement innovation -- only a month after the first custom apps came to light.
