Google Accused of Walling Off the Open Web to Retain Users

Google, once known for directing users to external websites, is increasingly being criticized for keeping users within its own ecosystem. The tech giant has been accused of restructuring its search and product features in ways that reduce traffic to third-party websites. Critics argue that features like AI-generated answers and knowledge panels discourage users from clicking through to original sources. This shift is seen as a strategic move to maximize user engagement and ad revenue within Google's own platforms. Observers warn that the trend poses a significant threat to the broader open internet and independent publishers.

Photo Ark Documents 18,000th Species: The Critically Endangered Red Handfish

Photographer Joel Sartore has spent 20 years documenting animal species through his Photo Ark project, which has now reached a milestone of 18,000 species recorded. The latest addition is the red handfish, a critically endangered marine species found on the seafloor. Unlike most fish, the red handfish uses its fin-like limbs to walk along the seabed rather than swim. Sartore launched the project with the goal of raising awareness about threatened wildlife around the world. He also hopes Photo Ark will serve as a lasting visual record of species that may eventually vanish from existence.

How a solar eclipse over India in 1868 led to the discovery of helium

During the 1868 solar eclipse observed in India, French astronomer Pierre Jules Janssen detected an unusual yellow spectral line that could not be explained at the time. The significance of the finding was not immediately understood, but British scientist Norman Lockyer later analyzed the data and named the unknown element helium, after the Greek sun god Helios. For nearly three decades, helium remained a purely astronomical observation with no confirmed presence on Earth. It was only in 1895 that Scottish chemist William Ramsay proved helium existed on Earth by successfully extracting it from a uranium-bearing mineral. The discovery highlighted how studying solar phenomena through spectroscopy could reveal elements before they were ever found on our own planet.
