They don't move like T. rex, but finding complete flower fossils from 100 million years ago is still quite a find. (Aug. 15, 2017)read more
Using telescopes in Hawaii and Chile, scientists have that the star Tau Ceti (12 light-years from Earth) and is orbited by four "super-Earths." The smallest of these newly found planets is almost twice the size of Earth. Two of the planets are thought to be in the...read more
SpaceX had a perfect launch of its Falcon 9 rocket this afternoon at Cape Canaveral, Launch Pad 39A. The first stage of the rocket was also recovered successfully. (Aug 14, 2017)read more
I learned today that Prof. Lotfi Zadeh has passed away. I had the great pleasure of many interactions with Lotfi, each with extreme kindness and encouragement. Many people were present at the birth of neural networks, and at the birth of evolutionary computation, but Lotfi was really the single first creative force of fuzzy logic. He’d say there was multi-valued logic before he had the idea for fuzzy membership but that would be a typical act of deference. I last saw Lotfi in Hong Kong in 2008 at the 2008 IEEE World Congress on Computational Intelligence while I was president of the IEEE Computational Intelligence Society. His soft-spoken strength was one of the many things I remember.
For those who might not know of Lotfi or of fuzzy sets, the concept is that things can be a member of a set with a degree of membership. So rather than 1 = you are a member of this set and 0 = you are not a member of this set, you can have membership between 0 and 1. And it turns out that there’s a lot of interesting math you can do with this concept and it’s very valuable in control applications, clustering, pattern recognition, and other artificial intelligence tasks.
True to this concept, Lotfi’s membership in the set of people who’ve passed away is higher now …. but not 1.0 as his work and memory live on with me and many others.
Experiments with a lunar rock collected in 1971 (Apollo 15 mission) from the "Sea of Rains" suggest that the moon maintained a weak magnetic field from 1 billion to 2.5 billion years ago. Previous theory suggested that the magnetic field had dissipated a billion years...read more

Changes to common roadside patterns, such as a stop sign, that would never fool a human driver can be problematic for a machine learning algorithm. Read more here. (Aug 4, 2017)read more
The gas giant WASP-121b is about 900 light-years from Earth, and scientists using the Hubble Space Telescope have used spectroscopy to identify water vapor in its stratosphere. (August 3, 2017)read more
