Cats are definitely smarter than dogs if this is true. Guess I should change my cat’s name from Dusty to Einstein or maybe Julius.

New research suggests that your cat might actually have a handle on some very basic physics, and can use it to help them hunt down hidden prey.

If the thought of your cat being better than you at physics — as well as being allowed to sleep all day — is getting you down, don’t worry, because we’re talking very simple cause-and-effect concepts here, and they only work when paired with cats’ extraordinary hearing and eyesight.

The research, led by scientists from Kyoto University in Japan, was following on from an earlier study that showed cats could predict whether or not an opaque container would have an object inside, based on whether it rattled or not.

A group of scientists confirmed that there is a pear-shaped nucleus. Not only does this violate some laws in physics, but also suggests that time travel is not possible.

A new form of atomic nuclei has been confirmed by scientists in a recent study published in the journal Physical Review Letters. The pear-shaped, asymmetrical nuclei, first observed in 2013 by researchers from CERN in the isotope Radium-224, is also present in the isotope Barium-144.

This is a monumental importance because most fundamental theories in physics are based on symmetry. This recent confirmation shows that it is possible to have a nuclei that has more mass on one side than the other. “This violates the theory of mirror symmetry and relates to the violation shown in the distribution of matter and antimatter in our Universe,” said Marcus Scheck of University of the West of Scotland, one of the authors of the study.

A new paper in AIP Advances argues that the controversial EM Drive doesn’t break physics as we know it, as it emits light (photons) as exhaust. However, other experts assert that it’s likely just an artifact.

Want to get people excited about science? Simple. Just post about EM Drive.

For those of you who may be new to the topic, EM Drive is a method of space travel that, if realized, would utterly transform our way of life. We could get to Mars in just 10 weeks (as opposed to the current 6+ month journey), and we could save a massive amount of money on fuel. We could have a truly viable space industry.

A new study published in Nature presents one of the most complete models of matter in the universe and predicts hundreds of massive black hole mergers each year observable with the second generation of gravitational wave detectors.

The model anticipated the massive black holes observed by the Laser Interferometer Gravitational-wave Observatory. The two colliding masses created the first directly detected gravitational waves and confirmed Einstein’s general theory of relativity.

“The universe isn’t the same everywhere,” said Richard O’Shaughnessy, assistant professor in RIT’s School of Mathematical Sciences, and co-author of the study led by Krzysztof Belczynski from Warsaw University. “Some places produce many more binary black holes than others. Our study takes these differences into careful account.”

Interesting.

The Science Council of Japan will make clear its position on military-linked research — possibly overturning a decades-long ban — by early next year, the academic group said Friday.

A committee of 15 academics from fields ranging from physics, political science to law held its first meeting to discuss whether to revise statements released by the council in 1950 and 1967 stating that the group will “never engage in military research.”

Over the next several months, the committee will hold five or six sessions to discuss how they should assess changes in the security and technology environment, how to define dual-use research, how studies tied to national security would impact academic transparency and how inflows of defense-related funding would alter the overall nature of research.

Sharing in case anyone is interested Prof. Scott Aaronson’s Computational discussion on “Complexity and Fundamental Physics”.

Summer continues, and the public lecture series on physics continues a pace at the Aspen Center for Physics with Dr. Catherine Heymans of the University of Edinburgh talking today on the “Dark Side of the Universe”.

The talk is part of one of the three workshops currently taking place:
