A 'Cosmic Positioning System' in the outer solar system‎

There have been plenty of attempts to resolve the "Hubble Tension" in cosmology. This feature describes how one of the most important variables in cosmology, the expansion of the universe, takes on different values depending on how you measure it. A new NASA Institute for Advanced Concepts (NIAC) Phase I report on the Cosmic Positioning System (CPS) details another potential solution to it—this one involving a network of five far-flung satellites spread throughout the solar system. The paper is posted to the arXiv preprint server.

'Fast-paced, fit, agile': Ableist words in job ads decrease applicants‎

An office job calls for a "fast-paced, fit and energetic" person who can "stand out" in a crowd. How likely are you to apply? A new University of Guelph study, led by Dr. Melissa Walker as part of her Ph.D., says that more neutral language might be key to drawing in more applicants of all ability levels.

Curiosity studies nodules on Mars boxwork formations‎

NASA's Curiosity Mars rover discovered these bumpy, pea-sized nodules while exploring a region filled with boxwork formations—low ridges standing roughly 3 to 6 feet (1 to 2 meters) tall with sandy hollows in between. This mosaic is made up of 50 individual images taken by Curiosity's Mars Hand Lens Imager (MAHLI), a camera on the end of the rover's robotic arm, on Aug. 21, 2025, the 4,636th Martian day (sol) of the mission. Ten images at different focus settings were taken at each of five locations to produce a sharp mosaic. The images were stitched together after being sent back to Earth.

Women more likely to choose wine from female winemakers‎

Promoting women's ownership in wineries can boost sales among the largest group of U.S. wine consumers, who happen to be women. Messages like "proudly made by a woman winemaker" increased women's intentions of purchasing wines, particularly when the label's artwork reinforced the point with feminine gender cues such as flowers. Women were also willing to pay higher prices for those wines, according to the research from Washington State University and Auburn University.

Past climate change: First indicators show resilience in tropical life—up to 1.5°C‎

New geological data indicate that marine life is somewhat resilient to warming in the tropics. Chris Fokkema, Earth scientist at Utrecht University, discovered that tropical algae were largely unaffected by a number of periods of global warming of up to 1.5 degrees Celsius in the distant past. These unicellular organisms form the basis of food webs and are generally very sensitive to rising temperatures. Previous studies of periods of even greater warming showed a dramatic decline in these organisms. "Somewhere beyond those 1.5 degrees, a tipping point occurs."

Meekness isn't weakness. Once considered positive, it's one of the 'undersung virtues' that deserve defense today‎

What do you envision when you think of meekness? You probably see a mousy doormat, someone sheepishly acquiescing to the will of the stronger. When Jesus says, "Blessed are the meek, for they shall inherit the earth," you might think that those wimps will hand it over without a whimper or word of objection to stronger, more ambitious people. The philosopher Friedrich Nietzsche called meekness "craven baseness."

Frictionless AI comes at a human cost to learning, growth and connection‎

Artificial intelligence is rapidly making intellectual work and social interaction easier, but that ease may come at a substantial psychological cost, according to researchers from the University of Toronto. In an article published in Communications Psychology, the authors argue that AI's greatest strength, namely removing friction from work and relationships, is also a liability.
