If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

A Statement of Our Values
By FOUNDATIONAL QUESTIONS INSTITUTE, FQXI • Jan. 18, 2023 @ 04:28 GMT

A number of reports have appeared recently that raise important questions about the integrity and values of philanthropic bodies and academic institutes, and their leadership.

The Foundational Questions Institute, FQXi, has a zero-tolerance policy for antisemitism, racism, misogyny, ableism, and other forms of oppression and hostility based on race, religion, caste, sexual orientation, or gender identity.

We at FQXi, would like to reiterate that we are committed to making science, in general, and the Institute, in particular, more equitable. Science is diverse, and so are scientists. There can be no doubt that scientific insight is not confined to one group of people but distributed across the whole of humanity.

We hold ourselves to these high standards. Any credible allegations of wrongdoing will be treated with the utmost seriousness.

Testing Time -- FQxI Podcast by Fabrizio Piacentini and Laura Knoll
By ZEEYA MERALI • Jan. 8, 2023 @ 18:20 GMT

Quantum physicists Fabrizio Piacentini and Laura Knoll discuss their recent experiment testing the predictions of Constructor Theory, a new meta-framework of physics that may encompass all other theories. The new framework could solve the mystery of why time marches in only one direction, even though the microscopic laws of physics are reversible.



Part 3 in the Irreversibility series.

Is Gravity Quantum? Deflecting Asteroids and Two Nuclear Fusion Breakthroughs -- FQxI Podcast by Zeeya Merali and Ian Durham
By ZEEYA MERALI • Jan. 8, 2023 @ 18:10 GMT

FQxI's Year in Physics Review concludes with part 3, as quantum physicist Ian Durham and Zeeya Merali reveal the number one physics advance of the 2022. Including an experiment demonstrating a weird quantum influence gravitational fields, NASA's DART mission to deflect asteroids and two major fusion results from the National Ignition Facility and First Light Fusion.

Space Telescopes, Charming Particles and Solving a Superconductivity Mystery -- FQxI Podcast by Zeeya Merali and Ian Durham
By ZEEYA MERALI • Jan. 8, 2023 @ 18:06 GMT

FQxI's Year in Physics Review continues with part 2, as quantum physicist Ian Durham and Zeeya Merali discuss the James Webb Space Telescope's groundbreaking astronomy images, quantum weather, how protons can contain charm quarks that are heavier than the protons themselves and the discovery of the tetraneutron. And solving a 35 year old puzzle about the mechanism behind high temperature superconductivity.
