Scientists suggest the Moon underwent a 'remelting' event due to tidal forces, resetting its geological clock and masking its true age with volcanic activity. This hypothesis could account for discrepancies in lunar-rock ages and impact basins, placing the Moon's formation between 4.43 and 4.53 billion years ago.
A 13,000-year history of vegetation and fire in Albany Pine Bush reveals pine-oak forest dominance with frequent fires. Pollen and charcoal samples indicate moister climates in recent millennia.
Researchers developed a miniaturized all-fiber photoacoustic spectrometer for intravascular gas detection, achieving detection limits of 9 ppb and response times as quick as 18 milliseconds. The system detects trace gases at the ppb level and analyzes nanoliter-sized samples with millisecond response times.
Scientists have developed swarms of tiny magnetic robots that can lift and transport heavy objects, thanks to their unique assembly configuration and rotating magnetic field. The microrobots can even guide small organisms through complex motions.
Researchers created human stem cell models containing notochord, a tissue guiding spine and nervous system formation. The model's chemical signals organize surrounding tissue similarly to natural development, enabling studies of developmental conditions and disorders.
A study by MIT economists suggests that industrial policy has a relatively limited impact on GDP growth, with average long-run gains of 1.08% in favorable circumstances. The research indicates that local consumer demand can curb the impact of industrial policy, putting a ceiling on directed growth.
A study by MedUni Vienna identified a promising therapeutic approach for metabolic liver diseases by targeting fat metabolism inhibition, promoting liver health and reducing liver fat, inflammation and fibrotic remodeling. The approach involves blocking ATGL, an enzyme playing a central role in lipid metabolism.
A new study from the University of Bath finds that personalized gifts can increase recipients' self-esteem and evoke a sense of vicarious pride. By including personal touches such as names or messages, gift-givers can create meaningful experiences that last beyond the initial gesture.
A new survey by Tel-Aviv University's Moshe Dayan Center reveals that 57.8% of Arab Israelis believe the ongoing war has fostered a sense of shared destiny between Arabs and Jews in Israel. This is a statistically significant shift from previous surveys, indicating a positive trend towards coexistence.
A new study reveals how doline topography supports diverse plant communities and act as biodiversity hotspots. Doline bottoms exhibit the highest functional and phylogenetic diversity.
A study found significant racial disparities in child abuse identification, with Black children suspected at higher rates. The findings highlight the need for further research to understand these disparities and reduce them in child abuse treatment.
A new method combining Random Forest and Compound Maximum a Posteriori algorithms reduces invalid transitions and improves LULC classification, correcting 99.92 km2 of errors. The study outperforms traditional methods, especially in detecting changes in mountainous regions.
Researchers uncovered a rare musical score in an ancient manuscript, shedding light on Scotland's musical traditions during the Reformation. The discovery provides clues to what music sounded like five centuries ago and is the only surviving piece from the northeast of Scotland.
Researchers have developed a molecule called azo-menthol that precisely controls TRPM8 channels using light, enabling spatiotemporally precise and reversible activation and deactivation. This breakthrough has great therapeutic potential for diseases such as cancer, metabolic disorders, and inflammations.
Researchers at Case Western Reserve University have discovered a potential target for treating drug-resistant malaria, PfNCR1, a cholesterol-managing protein. A compound known as MMV009108 can physically block the transporter, preventing it from doing its job and potentially killing the parasite.
Researchers have discovered that dextromethorphan, an FDA-approved ingredient found in many cough syrups, has potential to treat fibrotic lung disease. The study, published in Science Translational Medicine, showed how dextromethorphan can impede collagen formation, reducing lung scarring and stiffness.
A new study by UCL researchers found that AI systems amplify human biases, leading to a snowball effect where small initial biases increase the risk of human error. The researchers demonstrated real-world consequences, including overestimating white men's likelihood of holding high-status jobs and underestimating women's performance.
Researchers have developed a new diagnostic test that uses two markers found in the synovial fluid of patients' joints to differentiate osteoarthritis from inflammatory arthritis. The algorithm, based on the ratio of cartilage oligomeric matrix protein and interleukin-8, has been validated with high accuracy.
