A study in Physical Review D proposes that ancient black holes could have survived a cosmic bounce before the Big Bang, leaving behind relics that may still shape the Universe today. The research, led by Enrique Gaztañaga of the University of Portsmouth, explores a striking possibility: some black holes may be older than the hot…

Researchers at Northern Arizona University have found that a major global greenhouse gas database may be substantially undercounting carbon dioxide from cars and trucks in U.S. cities. The study, published in Environmental Research Letters, reports that Climate TRACE estimates for urban vehicle CO2 were about 70% lower on average than estimates from the Vulcan on-road…
Researchers at Yale University have created the largest map yet of Denisovan-inherited DNA in Near Oceanian populations, revealing thousands of ancient genetic variants that still influence gene activity in people today. The study, published on June 11, 2026, in Science, shows that DNA inherited from extinct human relatives continues to shape biology in modern populations…
Researchers at Nagoya University have identified an unexpected self-modifying behavior in a brain-related enzyme, according to a study in the Journal of Biological Chemistry. The enzyme, called ST8Sia5L, can build a long sugar chain on itself. That chain then helps control whether the enzyme stays quiet, leaves the cell and later becomes active again. The…
