The Pinzón saddleback tortoise, a small giant tortoise species native to Pinzón Island in the Galapagos characterized by a saddle-like curve in its shell. Credit: Evelyn Jensen Using a new computational toolkit, Yale researchers recovered evolutionary clues from highly degraded DNA and identified two extinct lineages of giant tortoises. Some Galapagos giant tortoise specimens preserved in museums contained so little usable DNA that less than 1% of their genomes could be read.

New Mexico’s Elephant Butte Reservoir was nearly full on June 2, 1994 (left), in contrast to very low levels during periods of drought on July 8, 2013 (center), and July 27, 2026 (right). The images were acquired with the TM (Thematic Mapper) on Landsat 5 and the OLI (Operational Land Imager) on Landsat 8 and Landsat 9.

Researchers found a possible link between abundant MAIT cells and an unusually strong response to lung cancer immunotherapy. The clue is now driving experiments aimed at turning a little-studied immune mechanism into a new treatment strategy.

Bacteria living inside lung tumors may be doing more than simply occupying the tumor environment.

The Med-South diet emphasized 2-6 daily servings of healthy-fat foods such as nuts, fish, avocado, vegetable oils, and full-fat dressings, along with at least seven servings of fruits and vegetables each day. Participants were also encouraged to eat beans and nuts at least three times a week, fish at least weekly, and poultry frequently, while limiting sugary drinks, sweets and pastries, and red or processed meats.

Dairy products such as milk, cheese, and yogurt are common sources of protein, calcium, and other nutrients, but researchers continue to examine how higher intake may affect long-term health.

A new national survey found that only 20% of men knew about the reported association between dairy consumption and prostate cancer.

This artist’s impression shows the temperate planet Ross 128 b, with its red dwarf parent star in the background. This planet, which lies only 11 light-years from Earth, was found by a team using ESO’s unique planet-hunting HARPS instrument. Credit: ESO/M. Kornmesser Solar system simulations starting from varied initial conditions suggest that Earth-like planets can emerge naturally from planet formation.

The Helix Nebula’s bright central region surrounds a white dwarf, the remnant of the star that created it. Farther out, newly revealed bow shocks trace material expelled by the dying star as it encounters surrounding interstellar gas. Credit: NASA, ESA, C. R. O’Dell (Vanderbilt University) and M. Meixner, P. McCullough and G. Bacon (Space Telescope Science Institute) A new image of the Helix Nebula reveals how dying stars return material to the galaxy.

A newly proposed “cosmic sandbar” could explain why certain lava-covered planets defy expectations about atmospheric loss. Credit: SciTechDaily.com Researchers developed a model showing how lava-covered planets close to their stars can hold onto their atmospheres, which could help guide the search for life beyond our solar system. Some planets orbit so close to their stars that intense radiation should strip away their atmospheres.

Triple-negative breast cancer is an aggressive form of breast cancer that lacks three common molecular targets—estrogen receptors, progesterone receptors, and HER2. Because many standard targeted treatments depend on these markers, the disease can be harder to treat and more likely to spread or return. Credit: Shutterstock Australian researchers have identified a promising new approach that could help stop one of the most aggressive forms of breast cancer from spreading.
