Rare sugars such as D-tagatose offer sweetness with fewer calories and a lower glycemic impact, but their production has long been inefficient and expensive. A new study demonstrates that a classic metabolic pathway, long thought to operate in only one direction, can be reversed inside living cells to make tagatose directly from glucose. The work introduces a potentially simpler and more scalable route to producing rare sugars, while also reshaping how scientists think about metabolic flexibility.

Since its launch, the James Webb Space Telescope (JWST) has identified a strange population of compact, ruby-colored objects in the distant universe known as “Little Red Dots” (LRDs). These objects presented a profound scientific paradox: they appeared to contain black holes far too massive for their host galaxies, yet they lacked the typical high-energy X-ray signatures associated with such behemoths. A landmark study published in Nature now offers a solution. By analyzing high-quality spectral data, researchers discovered that the light from these objects is being distorted by a dense “cocoon” of ionized gas. This finding reveals that the black holes are actually much smaller and younger than previously thought, representing a long-sought “missing link” in the history of cosmic growth.

Scientists have developed a minimally invasive workflow to recover biological data from centuries-old drawings and letters linked to Leonardo da Vinci. By combining advanced metagenomic sequencing with Y-chromosome analysis, the team identified a complex “composite biome” of bacteria, fungi, and plants, alongside a consistent paternal genetic signal (haplogroup E1b1b) across multiple items associated with the master artist and his ancestors.

A pair of fossil bones stored for decades in an Alaskan museum seemed poised to rewrite the story of woolly mammoth extinction. Their surprisingly young age suggested mammoths may have survived far longer than anyone realized. But deeper investigation uncovered a scientific twist that transformed a potential Ice Age breakthrough into an even more fascinating lesson about how science uncovers the truth.

Hydrogen is widely promoted as a key tool for decarbonizing industry and transportation, but its climate impact depends on what happens after it escapes into the air. A new scientific analysis maps hydrogen’s sources and sinks more comprehensively than before, highlighting unexpected contributors, including chemical production linked to reactive organic gases and strong regional patterns. The results suggest that managing hydrogen leakage and understanding natural emissions will be essential to ensuring a hydrogen-based energy transition truly delivers climate benefits.

NASA’s Nancy Grace Roman Space Telescope is an upcoming observatory designed to run some of the most ambitious surveys ever attempted in space astronomy. With a wide field view that can capture enormous patches of sky quickly, Roman will map how galaxies and matter have changed over cosmic time, a key clue to understanding dark energy and the universe’s accelerating expansion. At the same time, Roman will conduct a vast exoplanet census by watching for subtle brightening events that reveal distant planets, offering a statistically powerful view of how planetary systems form and evolve across the Milky Way. Roman also carries a high contrast coronagraph technology demonstration that will block starlight to help directly study faint worlds near bright stars, advancing the tools future missions may use to search for potentially habitable planets.

Researchers investigating natural anti cancer compounds have found that bee venom, particularly its main peptide melittin, can disrupt breast cancer cell membranes, trigger programmed cell death, and interfere with tumor growth signals. Early lab and animal findings are promising, but safety, dosing, delivery, and allergy risk mean human trials and targeted formulations are essential before any clinical use.

A surge in satellites, especially from mega constellations, is crowding low Earth orbit and raising the risk of catastrophic collisions. Researchers have developed a new metric, the CRASH Clock, to estimate how long it would take for a major to occur if satellites stopped dodging each other. Their analysis shows that this time has plummeted from 121 days in 2018 to just 2.8 days today, highlighting the urgent need for better space traffic management, international rules, and sustainable use of orbital space.

Archaeologists excavating a Viking-age grave in Trøndelag found a woman interred with high-status items and, most surprisingly, scallop shells placed near her jaw facing outward. It is the first documented example of this practice in a pre-Christian Viking burial, raising fresh questions about symbolism, status, and cultural connections in 9th-century Norway.

Researchers have identified thousands of short promoter-like DNA sequences that help extrachromosomal DNA stay inside dividing cells. These retention elements act as molecular anchors, are sensitive to epigenetic changes and are frequently found in tumor ecDNA. Their discovery offers a new explanation for how ecDNA persists and reveals an unexpected weakness that could be targeted in future treatments.

A high resolution XRISM observation captured the birth of an ultrafast outflow during a soft X ray flare from the active galaxy NGC 3783. The event revealed narrow iron absorption lines that appeared only during the flare decline and indicated a compact, fast moving clump launched from the inner accretion disk. Analysis suggests that magnetic reconnection, rather than radiation pressure, likely triggered the eruption. The discovery offers new insight into how black holes influence their surrounding environment.
