Webb telescope reveals colors of Earendel, most distant star ever detected
Detecting extremely distant stars, or those closest in time to the big bang, can provide insights into the first few chapters of the history of our universe. In 2022, the Hubble Space Telescope broke its own record, and spotted the most distant star yet. This star, nicknamed Earendel, emitted its light within the universe's first billion years.

After 15 years, pulsar timing yields evidence of cosmic background gravitational waves
LIGO confirmed the existence of gravitational waves in 2015, detecting one-time perturbations of spacetime from the merger of large black holes. There should be a background of gravitational waves permeating space due to other cataclysmic events in the cosmos, perhaps dating from the Big Bang. The NANOGrav consortium reports evidence from pulsar timing arrays that space is filled with such waves.

Losing long-lasting flockmates may drive a golden-crowned sparrow to stray from its favorite overwintering spot, a new study says, suggesting that friendly, familiar faces help anchor it to familiar spaces. The study found that a golden-crowned sparrow returning to California after a winter migration — one that can stretch as many as 3,000 miles — resettled an average of just 90 feet away from t

Research team makes surprising discovery of low-noise genes
While engaging in cell division research, Silke Hauf and members of her lab made a surprisingly quiet discovery. When cells express RNA, there is always some fluctuation, or noise, in how much RNA is produced. Hauf's group found several genes whose noise dips below a previously established threshold, known as the noise floor, during expression.

US municipal bond market pricing may be biased by race, unphased by climate risk

Erika Smull of Duke University, U.S., and colleagues present these findings in the open-access journal PLOS ONE on August 9.

How AI Could Predict the Outbreak of Infectious Diseases like Ebola
Disease Report AI's potential for analyzing mountains of data is unmatched. Take one of these AIs, set it loose on all the data in existence about the deadly Ebola virus, and the result could be nothing less than an unrivaled tool in fighting the virus — one that could save lives.
