For years, scientists thought Saturn’s moon Titan hid a global ocean beneath its frozen surface. A new look at Cassini data now suggests something very different: a thick, slushy interior with pockets of liquid water rather than an open sea. A subtle delay in how Titan deforms under Saturn’s gravity revealed this stickier structure. These slushy environments could still be promising places to search for life.

Superconductors promise loss-free electricity, but most only work at extreme cold. Hydrogen-rich materials changed that—yet their inner workings remained hidden because they only exist under enormous pressure. Now, researchers have directly measured the superconducting state of hydrogen sulfide using a novel tunneling method, confirming how its electrons pair so efficiently. The discovery brings room-temperature superconductors a step closer to reality.

Old military air samples turned out to be a treasure trove of biological DNA, allowing scientists to track moss spores over 35 years. The results show mosses now release spores up to a month earlier than in the 1990s. Even more surprising, the timing depends more on last year’s climate than current spring conditions. It’s a striking example of how fast ecosystems are adjusting to a warming world.

By studying tiny distortions in the shapes of distant galaxies, scientists mapped dark matter and dark energy across one of the largest sky surveys ever assembled. Their results back the standard picture of the universe and show that even archival telescope images can unlock cosmic mysteries.

Balanophora is a plant that abandoned photosynthesis long ago and now lives entirely as a parasite on tree roots, hidden in dark forest undergrowth. Scientists surveying rare populations across East Asian islands uncovered how its cellular machinery shrank but didn’t disappear, revealing unexpected similarities to parasites like malaria. Some island species even reproduce without sex, cloning themselves to colonize new habitats. This strange survival strategy comes with risks, leaving the plant highly vulnerable to habitat loss.

A major new meta-analysis finds that vegetarian and vegan diets can support healthy growth in children when properly planned. Kids on plant-based diets often had better heart health markers, including lower “bad” cholesterol, and consumed more fiber and vitamins. But the study also flagged common nutrient gaps—especially vitamin B12 and calcium—without supplementation. Experts say plant-based eating is achievable for kids, but only with careful planning.

Long before opioids flooded communities, something else was quietly changing—and it may have helped set the stage for today’s crisis. A new study finds that as church attendance dropped among middle-aged, less educated white Americans, deaths from overdoses, suicide, and alcohol-related disease began to rise. The trend started years before OxyContin appeared, suggesting the opioid epidemic intensified a problem already underway.

An instrument aboard NASA’s Europa Clipper spacecraft captured rare ultraviolet observations of an interstellar comet while Earth-based telescopes were blinded by the Sun. The spacecraft’s unique position provided an unprecedented look at the comet’s dust and plasma tails from an unusual angle. Scientists detected hydrogen, oxygen, and signs of intense gas release, hinting at powerful activity after the comet’s closest approach to the Sun. The findings may reveal clues about how comets form around other stars.

Getting ahead financially is mainly about what you earn at work, not what you make from investments. Researchers found that promotions, skills, and better jobs drive most upward income movement. But when people slip backward, falling investment income is usually the main reason. Labor builds income steadily; capital is riskier and more unpredictable.

Researchers have found that fossilized dinosaur eggshells contain a natural clock that can reveal when dinosaurs lived. The technique delivers surprisingly precise ages and could revolutionize how fossil sites around the world are dated.

Sorbitol, a popular sugar-free sweetener, may not be as harmless as its label suggests. Researchers found it can be turned into fructose in the liver, triggering effects similar to regular sugar. Gut bacteria can neutralize some of it—but too much sorbitol or glucose can overwhelm that defense. The result: yet another “healthy” sweetener that may stress the liver.

WASHINGTON, D.C.—Growth Energy, the nation’s largest biofuel trade association, applauded the Treasury Department and the Internal Revenue Service (IRS) today after the agencies published a notice for taxpayers seeking to claim the 45Q tax credit for carbon sequestration.  

American ethanol producers, and Growth Energy’s members in particular, are leaders in the deployment of carbon capture, utilization, and sequestration (CCUS) technology. Today’s notice provides a safe harbor that allows taxpayers to verify carbon sequestration, making it easier for participating biofuel producers to claim the 45Q tax credit for 2025. 

“American ethanol producers have always been on the cutting edge of carbon capture technology,” said Growth Energy CEO Emily Skor. “This safe harbor affirms the investments our members have made in CCUS today and supports more investment in CCUS in the future. We applaud the IRS and Treasury for working quickly to provide certainty for the 2025 tax year and look forward to working with them to continue supporting innovation and investment in rural communities across the U.S.”

Background 

Earlier this year, the U.S. Environmental Protection Agency (EPA) announced that it would reconsider the Greenhouse Gas Reporting Program, a part of which companies would use to verify and report their geologic carbon sequestration for the 45Q tax credit. Concerned about the impact of this proposal on those that rely on the program for verification, Growth Energy filed comments with EPA in November urging the agency to “do no harm” until a solution can be put in place by the Department of Treasury. With today’s action, IRS has provided such a solution, giving taxpayers a safe harbor to verify carbon sequestration they can use to claim the credit in 2025.

Researchers have revealed that so-called “junk DNA” contains powerful switches that help control brain cells linked to Alzheimer’s disease. By experimentally testing nearly 1,000 DNA switches in human astrocytes, scientists identified around 150 that truly influence gene activity—many tied to known Alzheimer’s risk genes. The findings help explain why many disease-linked genetic changes sit outside genes themselves. The resulting dataset is now being used to train AI systems to predict gene control more accurately.

In a rare and historic achievement, Children’s Hospital Colorado successfully completed its first dual heart and liver transplant in a pediatric patient. The life-saving surgery was performed on 11-year-old Gracie Greenlaw, whose congenital heart condition eventually led to liver failure. Dozens of specialists worked together for years to prepare for a moment like this, executing a complex, 16-hour operation. Now months later, Gracie is home, in school, and thriving.

After injury, the visual system can recover by growing new neural connections rather than replacing lost cells. Researchers found that surviving eye cells formed extra branches that restored communication with the brain. These new pathways worked much like the originals. The repair process, however, was slower or incomplete in females, pointing to important biological differences in recovery.

New research reveals when glaciers around the world will vanish and why every fraction of a degree of warming could decide their fate.

Spending a few hours a week helping others may slow the aging of the brain. Researchers found that both formal volunteering and informal acts, like helping neighbors or relatives, were linked to noticeably slower cognitive decline over time. The benefits added up year after year and didn’t require a huge time commitment. Even modest, everyday helping packed a powerful mental payoff.

Long before whales and sharks, enormous marine reptiles dominated the oceans with unmatched power. Scientists have reconstructed a 130-million-year-old marine ecosystem from Colombia and found predators operating at a food-chain level higher than any seen today. The ancient seas were bursting with life, from giant reptiles to rich invertebrate communities. This extreme complexity reveals how intense competition helped drive the evolution of modern marine ecosystems.

A small tweak to mitochondrial energy production led to big gains in health and longevity. Mice engineered to boost a protein that helps mitochondria work more efficiently lived longer and showed better metabolism, stronger muscles, and healthier fat tissue. Their cells produced more energy while dialing down oxidative stress and inflammation tied to aging. The results hint that improving cellular power output could help slow the aging process itself.

A new bioluminescent tool allows neurons to glow on their own, letting scientists track brain activity without harmful lasers or fading signals. The advance makes it possible to watch individual brain cells fire for hours, offering a clearer, deeper look at how the brain works.
