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.

Rio de Janeiro Uses Salon Hair Waste to Shield Mangroves from Oil Pollution

An environmental initiative in Rio de Janeiro is repurposing discarded human hair from salons to create barriers that block oil pollution in Guanabara Bay. Each gram of hair can absorb around five grams of oil while naturally repelling water, making it an effective filtration material. These barriers can remain functional in water for up to four months before replacement. The project specifically targets the protection of mangrove ecosystems, which are particularly vulnerable to chronic, everyday oil leaks. Organizers hope the effort will support the broader recovery of marine life within the bay.
