Science advances precision timing and fusion while biosafety questions persist

Day’s Recap

Supporting Articles

Scientists in Vienna have built the first self-stabilizing nuclear clock, using transitions in thorium nuclei rather than electrons in atoms. Because nuclei are less vulnerable to environmental interference, the design could eventually outperform today's most precise atomic clocks.

Researchers at Princeton Plasma Physics Laboratory propose reversing the usual fusion sequence by heating plasma before compressing it to higher density. Their calculations suggest this approach could reduce the energy needed to reach self-sustaining fusion and avoid instability that complicates ignition.

Russian authorities have not identified the pathogen that killed a plague researcher one week after the death. Experts say modern testing should have produced an answer by now.

A curated list of other prominent stories from this day.

Researchers recreated birch tar using prehistoric production methods and found that every sample inhibited bacteria associated with serious wound infections. The results suggest Neanderthals may have used the substance not only as an adhesive but also as a treatment for injuries.

Astronomers identified a system about 300 light-years away in which a small star is gradually pulling material from a nearby brown dwarf. The slow transfer differs from the rapid destruction seen in many stellar mergers and could continue for billions of years.

Colossal Biosciences CEO Ben Lamm argues that efforts to revive extinct species such as dire wolves and woolly mammoths could advance conservation, healthcare, and developmental biology. The proposed benefits would come from the underlying genetic and reproductive technologies, not only from recreating the animals.
