A new study examined whether phone tutoring could offset learning losses when schools close, finding that students who received such tutoring showed measurable gains in math performance compared to peers without access to it. The research points to remote, low-tech tutoring as a viable stopgap during disruptions to in-person schooling.
Researchers examining a set of unusual ancient fossils found evidence that the earliest insects were far more anatomically varied than previously assumed. The specimens display body structures that don't fit neatly into existing insect classification schemes, complicating the picture of how insects first diversified.
Scientists have discovered a protein, nicknamed 'superdark' for its poorly characterized status, that structurally resembles a G-protein-coupled receptor (GPCR) but does not behave like typical members of this receptor family. The finding suggests the protein may represent an unusual or previously unrecognized branch of GPCR-like signaling molecules.
A large-scale genetic study analyzed data from roughly one million people to identify genetic variants associated with the Big Five personality traits—openness, conscientiousness, extraversion, agreeableness, and neuroticism. The research aimed to uncover the biological underpinnings of personality by pinpointing specific genomic regions correlated with these traits.
Researchers used family-based genetic analyses to examine how inherited genetic variants influence important traits in children, such as growth, cognition, or behavior. The approach controls for shared family environment and population structure, allowing more precise estimates of direct genetic effects than standard population studies.
Researchers report that water droplets carrying electric charge erode surfaces more aggressively than neutral droplets upon impact. The finding, published via Nature.com, points to charge as an overlooked factor in droplet-driven erosion processes.
Researchers found that achieving a more uniform film-formation process during the fabrication of perovskite-based tandem solar cells improves both their performance and durability. The finding points to film uniformity as a key factor in reducing defects that typically degrade these cells over time.
Scientists have developed a drug delivery approach that targets specific structures within individual cells rather than simply reaching a cell as a whole. This subcellular precision aims to route therapeutic payloads to particular organelles or compartments where they can act most effectively.
Scientists are developing intranasal vaccines designed to trigger immunity directly in the nose and upper airway, the entry point for many respiratory pathogens. Unlike injected vaccines that mainly prevent severe illness, these formulations aim to stop infection and transmission before a virus can spread further.
Researchers are redesigning drug molecules and delivery systems so a single injection or implant can maintain therapeutic effects for weeks, months, or even years instead of requiring daily dosing. Techniques include chemical modifications that slow drug breakdown, polymer depots, and implantable devices that release medication gradually over extended periods.
A Nature piece argues that even well-designed drugs fail patients if they cannot reach the intended biological target effectively. The commentary highlights delivery mechanisms and targeting accuracy as critical, often underappreciated, factors in therapeutic success.
A Nature editorial argues that a substantial share of prescribed medicines fail to help patients simply because they are not taken as directed. It calls for more research and health-system attention on why patients skip or stop treatments, rather than focusing solely on drug development.
