A phenanthrene co-guest helps crystalline sponges reveal 3D structures of small, low-polarity molecules

Adding phenanthrene as a co-guest let the second-generation crystalline sponge (2G-CS) method determine X-ray structures for 24 of 30 small, low-polarity C₁₅ molecules, mostly sesquiterpenoids. Under standard conditions, none of the 30 gave guest-containing crystals. Eleven of the 24 structures had not been reported before, including that of the liquid hydrocarbon longifolene. A chiral version of the cage gave the absolute configurations of five compounds.

400,000-year-old teeth reveal a stunning twist in human evolution

A groundbreaking discovery is rewriting the story of human evolution, revealing that an ancient human species once thought to be an evolutionary dead end may have left genetic traces in people alive today. By extracting proteins from 400,000-year-old Homo erectus teeth discovered in China, scientists uncovered evidence suggesting that these early humans interbred with Denisovans, another mysterious ancient human group. That genetic connection may have eventually reached modern populations in the Philippines, Papua New Guinea, and other parts of Southeast Asia.

Where U.S. states rank on new housing supply pipeline

In order to know where you're going, you must know where you've been, says an old adage. And a new UNLV housing supply rankings report is putting that proverb into practice by providing policymakers and the public with the nation's first comprehensive look at how state-level new home permitting activity stacks up—and offering clues on local, state or regional measures that could help drive down skyrocketing prices.

Scientists discover mysterious “lonely” brain waves linked to memory loss

Scientists have uncovered a surprising link between Alzheimer’s-related protein buildup, disrupted brain waves during deep sleep, and fading memory. The findings suggest that hidden changes in how the brain processes memories overnight may contribute to age-related memory loss long before Alzheimer’s symptoms appear.

Historic duck DNA traces wild mallard genetic changes to more than a century of releases

Researchers have long known that releasing domesticated ducks can alter wild populations. Now, a study led by a doctoral student at The University of Texas at El Paso has documented, for the first time in North America, when and where these genetic changes took place and tied them directly to more than a century of releases.

Ultrasound reveals hidden tongue movements behind centuries-old language change

Scientists at Lancaster University have observed the hidden tongue movements accompanying a centuries-old change in English speech—offering a rare glimpse of language transforming in real time. Linguists have used ultrasound imaging to observe one of these changes as it unfolds inside the mouths of speakers from Blackburn, Lancashire—one of the few places in England where many older speakers still pronounce the historical strong-R sound after vowels in words like star and heart.

Goodbye, cavities? Scientists create gel that could regrow tooth enamel

Scientists have developed a revolutionary gel that could regrow lost tooth enamel by harnessing minerals naturally found in saliva, potentially overcoming one of dentistry’s biggest limitations. The regenerated enamel behaves much like healthy enamel, raising hopes for a simple treatment that could repair damaged teeth, prevent decay, and reduce sensitivity.

Scientists solve 30-year-old mystery and discover a hidden defense against inflammation

Scientists have solved a decades-old mystery and uncovered a hidden immune system defense that protects healthy cells from the very inflammation meant to fight infections. The surprising discovery could lead to new approaches for treating cancer, inflammatory bowel disease, and other conditions involving excessive inflammation.

Centuries-old cemetery helps scientists link climate shocks to Industrial Revolution disease

During England's Industrial Revolution, when the country's farming-based economy transformed into an industrial one between roughly 1760 and 1840, pollution, harsh working conditions, inadequate housing and limited access to sunlight drove disease. Rickets, in which the growing skeleton fails to properly mineralize, was commonplace among children. Traditionally, urbanization, latitude and socioeconomic status were considered the main drivers. A factor that has largely been overlooked is climate.

A tiny supercurrent could unlock quantum information without destroying it

Researchers have proposed a breakthrough technique for reading quantum information without destroying the delicate states that make quantum computers work. By detecting an electrical signal generated by the qubit itself, their method achieved up to 99.85% accuracy in simulations and could make future quantum computers simpler and more efficient.

Scientists turn viruses into weapons against deadly superbugs

Scientists are advancing a promising new way to fight antibiotic-resistant infections by using viruses that specifically target and kill harmful bacteria. An international team has released the first coordinated guidelines for personalized phage therapy, offering a roadmap for safely bringing this experimental treatment into clinical practice. Early findings are encouraging, with one study reporting improvement in 77% of patients and the disappearance of targeted bacteria in 61%.

A new route to calculating gluon production in proton–nucleus collisions

In the theoretical study of proton-nucleus collisions, the colliding projectiles can be described as streams of color charges moving along their respective trajectories. These color charges couple to gluons, which then produce the particles that are observed in the final state (gluons and quarks, which eventually produce hadrons).
