New research questions whether memory reliably reflects reality. What if your entire past never actually happened? That unsettling idea is at the center of a new study by SFI Professor David Wolpert, SFI Fractal Faculty member Carlo Rovelli, and physicist Jordan Scharnhorst. They revisit the “Boltzmann brain” hypothesis, a thought experiment that has challenged physicists […]

Students Found an Ancient Star That Shouldn’t Be in the Milky Way
Students discovered an ultra-ancient star with almost no heavy elements, making it one of the most pristine ever found. Surprisingly, it appears to have formed in another galaxy before drifting into the Milky Way. A team of undergraduate students at the University of Chicago has identified one of the oldest known stars in the universe […]
Astronomers Solve 50-Year Mystery and Reveal Hidden Culprit Behind Strange X-Ray Emissions
Astronomers have finally identified the source of unusual X-rays from the bright star gamma-Cas, resolving a decades-long mystery. Astronomers have finally solved a decades-old puzzle surrounding the bright star gamma-Cas, identifying an unseen companion as the source of its unusual X-rays. This hidden object is pulling in material from the visible star, generating powerful high-energy […]
One of the Universe’s Largest Stars May Be Getting Ready To Explode
A massive star’s sudden transformation may signal an approaching supernova. One of the largest stars ever discovered has undergone a dramatic transformation, and scientists believe it may be nearing a violent end. New research led by Gonzalo Muñoz-Sanchez at the National Observatory of Athens, published in Nature Astronomy, finds that the enormous star WOH G64 […]
Scientists Discover Enzyme That Could Supercharge Ozempic-Like Weight Loss Drugs
Researchers have identified a versatile enzyme capable of reshaping peptide-based drugs into more stable, longer-lasting forms. Chemistry researchers at the University of Utah have identified an enzyme called PapB that can “tie off” therapeutic peptides, which are protein-like drugs, into compact ring structures. This process is known as macrocyclization. According to new research, this approach […]
Asthma and Depression Don’t Mix the Way Scientists Expected
Depressive symptoms are common in people with asthma, but increasing evidence suggests they may be driven by biological processes that differ from those seen in major depressive disorder. Researchers from Hiroshima University in Japan, working with collaborators, have identified a biological difference in how depression appears in adults with asthma. Their study found that people […]
