Dialog / From spider webs to mosaics: How nanosheets of graphene oxide control the patterns left by a drying droplet
A drop of coffee on a tabletop often leaves a dark ring behind. This everyday mark is a reminder that a drying droplet is not passive: As water evaporates, it can transport the particles suspended inside it toward the edge. ...
Phys.org / Scientists reveal how our cells conduct emergency repairs for DNA
Two new studies from Johns Hopkins University are providing scientists with an unprecedented view of how human cells repair one of the most dangerous forms of genetic damage: a break that severs both strands of the DNA double ...
Medical Xpress / Newborn girls and boys show different attention patterns within hours of birth
Cambridge scientists have shown that girls and boys differ in what they pay attention to, even at birth. Since these differences are present so early, it is possible they emerge due to prenatal factors. The findings suggest ...
Phys.org / Engineered nanoparticles sensitize gliomas to radiotherapy
Gliomas are a major cause of cancer-related deaths in younger adults. About 7,000 patients harbor a common genetic mutation that affects the enzyme isocitrate dehydrogenase 1. This mutated enzyme, called mIDH1, can produce ...
Phys.org / The monsters that weren't: Dinosaur and tusked-beast claims in San rock art unravel
For decades, an idea has grown in paleontology that, long before scientists began digging up and reconstructing dinosaur bones, the Indigenous San and Basotho in southern Africa noticed them too, incorporating them into songs, ...
Phys.org / How the pro‑nicotine 'wellness' movement rebranded an addictive drug
An ironic development emerging alongside the "Make America Healthy Again" movement is the portrayal of nicotine as a wellness and performance-enhancing product. Across social media, podcasts, wellness communities and tech ...
Tech Xplore / Toward physical AI: When the hardware becomes the neural network
Digital computing using silicon chips has transformed nearly every aspect of modern life and enabled the remarkable growth of artificial intelligence. But as AI models scale up, that growth comes with increasing demands for ...
Phys.org / A 'rebellious' exoplanet orbits in the opposite direction of its star
A star and its planets form when a cloud of gas and dust collapses in on itself somewhere in space. The cloud then forms a disk around the nascent star, within which the planets will form. This protostar and its disk then ...
Phys.org / New nanoparticle drug-delivery method may improve treatment for endometriosis
Researchers have engineered a drug treatment that shows rapid effectiveness against endometriosis in early testing, laying the foundation for a potential therapy for an incurable, chronic disease that affects 1 in 10 women. ...
Phys.org / New ligand design balances radical generation and catalyst regeneration for challenging chemical reactions
Radicals, atoms or molecules that readily react with other substances to form new bonds, are useful tools for building complex substances such as pharmaceuticals. But even when a radical is generated efficiently, the reaction ...
Medical Xpress / Two protective genetic pathways may converge to reduce Alzheimer's disease risk
Alzheimer's disease is the most common form of dementia worldwide. Although the APOE ε4 allele is the strongest genetic risk factor for late-onset Alzheimer's disease, not all carriers develop dementia, indicating that other ...
Phys.org / Plasma technology could help plant-based packaging replace plastic
A new study has found a sustainable and scalable way to improve the durability of plant-based packaging; it's a discovery that researchers say could help curb the environmental footprint of plastic. Researchers used advanced ...
