Two Cancer Signaling Pathways Enable More Personalized Treatment for Papillary Thyroid Cancer
In papillary thyroid carcinoma (PTC), cancer progression is increasingly understood as a product of two intertwined signaling engines: MAPK and PI3K/AKT. While these pathways normally...
Fabric Enables Multiple Stable Shapes Using Snap-Like Structural Design
Knitting has evolved beyond comfort wear. In a new study from Harvard SEAS, researchers demonstrate how ordinary weft knitting can be engineered into shape-shifting textiles...
Fine-flavor native cacao matches commercial yields, study shows
A new multi-year field study from Peru’s Piura region challenges a long-held assumption in cocoa agriculture: native fine-flavor cacao may be just as productive as...
Study uncovers ultrafast gene evolution driving chicken feather color diversity
Domestic chickens have long fascinated biologists with their feather diversity—ranging from barred and speckled patterns to uniform black and crisp snowy white. For centuries, selective...
Saber-Toothed Cats’ Spinal Tumors Reveal How Inbreeding Threatened Survival
Saber-toothed cats (Smilodon fatalis) from the La Brea Tar Pits preserve more than just bones—they also retain a medical record of what may have been...
CCHFV Polymerase Enables RNA Synthesis and Shows Substrate Analog Inhibition
Viral polymerases of the Nairoviridae family are unusually large, and until now their atomic details have remained largely unexplored. In a new study, researchers report...
Infection Study Maps Protein Contact Sites, Shows Influenza Hijacks Paraspeckles
Influenza A virus is infamous for its speed—yet the molecular choreography inside infected cells is still being uncovered. In a new study published in Nature...
Potassium Approaches Plasmonics’ Low Optical Loss Limit
Potassium is stepping into the spotlight as researchers report a new route toward the elusive low-loss performance limit in plasmonics. In a study published in...
Highly chemoselective access to alkyl-sulfur compounds via N2 extrusion of alkyl hydrazines
Sulfur(VI)-containing functional groups, such as sulfonamides, sulfinates and sulfonyl fluorides, are ubiquitous in pharmaceuticals, where they confer unique physicochemical properties that enhance metabolic stability, solubility...
Bulk Acoustic Resonator with Vertical Electrodes Enables Wideband Filters
A team led by Stettler, Navarro-Gessé, Collado and colleagues has unveiled a new kind of bulk acoustic resonator (BAR) designed specifically to expand the bandwidth...
Microbe Lactic Acid Weakens Interferon by Blocking Antiviral Signaling
A study in Nature Communications reports that lactic acid produced by host cells can blunt the antiviral power of interferons (IFNs), reshaping how innate immune...
Flexible Payments for Environmental Services Boost Cost-Effectiveness in Brazilian Amazon
A new study suggests that tweaking how payments for environmental services (PES) work could make them significantly more cost-effective in the Brazilian Amazon. Researchers report...
Meta-analysis Compares Nasal Interfaces and Face Masks During Preterm Birth Respiratory Support
About 10% of newborns need breathing assistance immediately after birth, and premature infants are among those most likely to require it. In delivery rooms, clinicians...
