A Miracle of St. Therese –

Below is one miracle recounted through the intercession of St. Therese. On March 3, 1972, Nogent-le-Roi’s firefighters took me to the hospital in Dreux after I fell off a horse. I had lost consciousness, and my scalp was bleeding profusely. Two days later, I was still unconscious. My condition had worsened, and an ambulance drove… Continue reading A Miracle of St. Therese –

Scientists Solve Star Spin Mystery

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

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

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
