  PARIS — As operators of Earth observation satellites prepare to update their fleets, with an emphasis on both improved resolution and revisit time, they disagree on how much demand there is for existing and new data. Four companies that currently operate Earth observation satellites, from high-resolution optical spacecraft to synthetic aperture radar (SAR) satellites,

  The ancient city of Hasankeyf, which sits on the banks of the Tigris River in southeastern Turkey, is believed to be one of the world’s oldest continuously inhabited settlements, with a human history stretching back some 10,000 years. Neolithic peoples carved caves into cliff sides, and Hasankeyf’s modern inhabitants continue to live in those

When viewed under a fluorescence microscope, the individual probes light up each RNA in an individual cell. By using a color combination method, UD molecular biologist Mona Batish is able to distinguish which tagged RNA are linear (yellow) and circular (green). Credit: Kathy F.

Halting deforestation, reducing forest degradation, and protecting intact forests are essential, but alone these actions are not sufficient to reduce biodiversity loss, mitigate climate change, and improve sustainable land

What determines global patterns of biodiversity has been a puzzle for scientists since the days of von Humboldt, Darwin, and Wallace. Yet, despite two centuries of research, this question remains unanswered. The global pattern of mountain biodiversity, and the extraordinarily high richness in tropical mountains in particular, is documented in two companion Science review papers

JILA/NIST physicist Adam Kaufman adjusts the set-up for a laser that controls and cools the strontium atoms in the optical tweezer clock. The atoms are trapped individually by 10 tweezers — laser light focused into tiny spots — inside the square orange container behind Kaufman’s hand.

  It’s not as if the world needed another symbol for the climate crisis, but now Sweden has one all to itself. After years of rising temperatures and back-to-back summer heatwaves, the southern peak of Kebnekaise, Sweden’s former tallest mountain, has melted into subservience. For decades, the glacier atop this iconic summit has been in retreat,

Smoke from a summer wildfire is more than just an eye-stinging plume of nuisance. It’s a poison to the lungs and hearts of the people who breathe it in and a dense blanket that hampers firefighting operations. There’s an atmospheric feedback loop, says University of Utah atmospheric scientist Adam Kochanski, that can lock smoke in

The latest view of Saturn from NASA’s Hubble Space Telescope captures exquisite details of the ring system — which looks like a phonograph record with grooves that represent detailed structure within the rings — and atmospheric details that once could only be captured by spacecraft visiting the distant world. Hubble’s Wide Field Camera 3 observed
