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.

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.
