In mice, cells in the hypothalamus clear out old memories while the animals sleep.

The news: According to a report in the Financial Times, a team of researchers from Google led by John Martinis have demonstrated quantum supremacy for the first time. This is the point at which a quantum computer is shown to be capable of performing a task that’s beyond the reach of even the most powerful conventional supercomputer. The claim appeared in a paper that was posted on a NASA website, but the publication was then taken down. Google did not respond to a request for comment from MIT Technology Review.

Why NASA? Google struck an agreement last year to use supercomputers available to NASA as benchmarks for its supremacy experiments. According to the Financial Times report, the paper said that Google’s quantum processor was able to perform a calculation in three minutes and 20 seconds that would take today’s most advanced supercomputer, known as Summit, around 10,000 years. In the paper, the researchers said that, to their knowledge, the experiment “marks the first computation that can only be performed on a quantum processor.”

Quantum speed up: Quantum machines are so powerful because they harness quantum bits, or qubits. Unlike classical bits, which are either a 1 or a 0, qubits can be in a kind of combination of both at the same time. Thanks to other quantum phenomena, which are described in our explainer here, quantum computers can crunch large amounts of data in parallel that conventional machines have to work through sequentially. Scientists have been working for years to demonstrate that the machines can definitively outperform conventional ones.

The first population-level study on the link between gut bacteria and mental health identifies specific gut bacteria linked to depression and provides evidence that a wide range of gut bacteria can produce neuroactive compounds. Jeroen Raes (VIB-KU Leuven) and his team published these results today in the scientific journal Nature Microbiology.[br /][br /].

Now this is encouraging technology.

The MagLab’s Cryogenics group does research and development to advance the field and supports technology using specialized facilities and equipment.

Is this the solution to stop humans from trashing the planet?

After a 10-month journey from Earth, the MAVEN spacecraft entered Mars orbit on September 21, 2014. The mission €”originally planned to gather data for one-Earth-year €”continues to provide unique insight into the history of #Mars ’ atmosphere and climate, liquid water, and planetary habitability.

It is a tremendous credit to the entire MAVEN team that the instruments and spacecraft continue to operate well and that the science continues to provide exciting results related to the #Martian upper atmosphere, ionosphere, and interactions with the Sun and solar wind.
