Astronomers can measure how fast stars spin by observing “starquakes”—seismic tremors that are the equivalent of earthquakes on our planet. Yet these observations have posed a puzzle because many stars seem to be spinning slower than they should be. In a new study, researchers modeled how a magnetic field could grow in the internal layers… Continue reading Scientists Solve Star Spin Mystery
Arming Teachers, F-16s in Ukraine, Commercial Spaceflight: RAND Weekly Recap
This week, we discuss teachers’ views on carrying guns and on school safety overall; what F-16s will (and won’t) do for Ukraine; regulating commercial spaceflight; the future of Chinese psychological warfare; the parallels between Putin and Brezhnev; and who we honor on Memorial Day. A memorial outside Robb Elementary, where a gunman killed 19 children… Continue reading Arming Teachers, F-16s in Ukraine, Commercial Spaceflight: RAND Weekly Recap
The Call to Integrity in Worship
The opening of the Book of Isaiah is provocative, especially for those of us who hold the Liturgy in high esteem, as well we should. However, it is possible for us to distort even great things like the Mass and the sacraments. Let’s look at the reading and then draw a few teachings from it:… Continue reading The Call to Integrity in Worship

America Is Winning Against China in Oceania
April 20, 2022, was a dark day for the United States in Oceania. On that day, China signed its first-ever security agreement in the South Pacific, with the Solomon Islands authorizing Chinese navy ships to make routine port visits. The pact also allows Chinese security services to train the island nation’s law enforcement to, in… Continue reading America Is Winning Against China in Oceania
Scientists Create Human Embryo-Like Structures with Stem Cells
Scientists have created synthetic blobs that resemble a 14-day-old human embryo for the first time, meaning they can study embryo development beyond a particularly tricky period of pregnancy. Historically, international rules prevent research on human embryos more than 14 days after fertilization. But the new technique uses stem cells, which have the potential to transform… Continue reading Scientists Create Human Embryo-Like Structures with Stem Cells
Amid an Epidemic of Loneliness, Nonprofits Are Helping Keep Veterans Connected
The U.S. surgeon general recently issued an advisory on America’s loneliness epidemic (PDF) and the healing effects of social connection. Former Department of Veterans Affairs (VA) Secretary Bob McDonald also issued a statement on veterans’ social isolation. These are important reminders of veterans’ need for connection and community. Fortunately, there are many nonprofit organizations seeking… Continue reading Amid an Epidemic of Loneliness, Nonprofits Are Helping Keep Veterans Connected
Loving With the Sacred Heart of Jesus
One of the most common depictions of Jesus in Western art outside the crucifixion is the depiction of the Most Sacred Heart of Jesus. All of these depictions show Our Lord’s closeness, tenderness, and love toward all of us. Out of the varying depictions of the Sacred Heart, there is one unique feature of all… Continue reading Loving With the Sacred Heart of Jesus
Sparse Neural Networks Point Physicists to Useful Data
Graham tried tweaking the CNN approach so that the kernel would only be placed on 3-by-3 sections of the image that contain at least one pixel that has nonzero value (and is not just blank). In this way, he succeeded in producing a system that could efficiently identify handwritten Chinese. It won a 2013 competition… Continue reading Sparse Neural Networks Point Physicists to Useful Data
U.S.-China Rivalry in an Era of Weakening States
In his recent meeting with Chinese Foreign Minister Qin Gang, U.S. Ambassador Nicholas Burns reportedly emphasized the importance of stabilizing the bilateral relationship. After an alarming downturn in U.S.-China relations, an easing of tensions could indeed provide a welcome breather for two countries confronting intractable domestic problems. Washington continues to grapple with slowing growth, bitter… Continue reading U.S.-China Rivalry in an Era of Weakening States
