Earlier this year, I published a post showing our results of the interferometric imaging of Cassiopeia A and Cygnus A at 4.9 GHz with the Allen Telescope Array . Near the end of July, I decided to perform more interferometric observations of Cygnus A at a higher frequency, in order to obtain better resolution. I chose…
NASA’s selection of SpaceX’s Starship within the Human Lander System (HLS) program was both surprising and exciting for space nerds all over. Previously I have written about how Starshi…
"The bellows are burned, the lead is consumed of the fire; the founder melteth in vain: for the wicked are not plucked away. Reprobate silver shall men call them, because the Lord hath rejected them."
Researchers discover how accurately the human ear can detect time delay in sounds in different frequencies.
The long view of economic history says we're in the midst of a huge, unsustainable acceleration. What happens next?
Can high school students really learn algebraic geometry? And what could it teach us about mathematics education?
A couple of months ago a new paper was released that examined the lead-crime hypothesis. Its conclusion is that there's little evidence for an association, and if there is one it's pretty small. I haven't commented on it, but not because of its negative conclusion. It's because the paper is a meta-analysis. I'm fairly…
The Carlson School of Management research showed replicated and expanded on what was previously found: bronze medalists were more likely to exhibit a smile than silver medalists, while gold medalists were happier than other medalists.
Fulfilling a prediction of Einstein’s theory of general relativity, researchers report the first-ever recordings of X-ray emissions from the far side of a black hole.
Are there early indicators that could help predict which individuals will go on to develop this serious mental illness? New research by Distinguished Professor Mark F. Lenzenweger could point the way.

I heard this morning the news that Steven Weinberg passed away yesterday at the age of 88. He was arguably the dominant figure in theoretical particle physics during its period of great success fr…
Research team now examines impact of food competition and climate change
Nature has now released that AlphaFold 2 paper , after eight long months of waiting. The main text reports more or less what we have known for nearly a year, with some added tidbits, although it is accompanied by a painstaking description of the architecture in the supplementary information . Perhaps more importantly…

I'm always in the market for surprising facts. One of my favorites is that the color blue is always out of focus for the human eye. It's hard to believe since it appears that we see blue clearly, but it's astonishing when shown an example. Here', I'll explain why we're unable to focus on blue, and show examples of…
DURHAM, N.C. -- A surgical team at Duke University Hospital, led by Drs. Jacob Schroder and Carmelo Milano, successfully implanted a new-generation artificial heart in a 39-year-old man with heart failure, becoming the first center in North America to perform the procedure.
Cases are growing exponentially across the world. Again. If you don’t know where this is going, a historical refresher might help. India has suffered about two million COVID deaths, the majority of them during its latest surge caused by Delta.Victims of COVID-19 are cremated in funeral pyres in New Delhi.
By Lindsay Brownell At first glance, the lab of Wyss Associate Faculty member Mike Levin looks like any standard biology lab: graduate students in white lab coats pipette liquids into tubes at benches surrounded by centrifuges, freezers, racks of graduated cylinders hanging over sinks, and shelves of petri dishes…
Mathematician: That depends on what you mean by “universe.” Here’s a framing: A circle of radius R centered at a point P is the set of all points in the plane with distance R fro…
