Report: U.S. Cancer Rates Have Fallen for at Least 25 Years

Although that is good news, cancer is the second-most common cause of death in the U.S., with more than 1.7 million new cancer cases each year and more than 600,000 cancer deaths. The report notes that one of the biggest factors in decreased cancer rates are lower tobacco smoking rates.

Saturn hasn’t always had rings

In its last days, the Cassini spacecraft looped between Saturn and its rings so that Earth-based radio telescopes could track the gravitational tug of each. Scientists have now used these measurements to determine the mass of the rings and estimate its age, which is young: 10-100 million years. This supports the hypothesis that the rings are rubble from a comet or Kuiper Belt object captured late in Saturn’s history.

A Choice of Grippers Helps Dual-Arm Robot Pick Up Objects Faster Than Ever

Dex-Net 4.0 enables “ambidextrous” robots to choose the best gripper for the job

We’ve been following Dex-Net’s progress towards universal grasping for several years now, and today in a paper in Science Robotics, UC Berkeley is presenting Dex-Net 4.0. The new and exciting bit about this latest version of Dex-Net is that it’s able to successfully grasp 95 percent of unseen objects at a rate of 300 per hour, thanks to some added ambidexterity that lets the robot dynamically choose between two different kinds of grippers.
