Phys.org / Nanorobots based on reconfigurable DNA origami arrays can work autonomously
Over the past decades, a growing number of robotics teams have started developing modular robots inspired by the ancient paper-folding art of origami. More recently, some of these teams started experimenting with origami ...
Phys.org / Generative chatbots promise personalized education at scale but struggle with accuracy issues
Personalized learning is a very effective teaching method, but its potential is limited due to resource constraints. In a small, in-person class, instructors can walk around, engage with students individually, adjust lessons ...
Phys.org / Cleveland's famous sea monster gets a scientific update
About 360 million years ago, the shallow sea above present-day Cleveland was home to a fearsome apex predator: Dunkleosteus terrelli. This 14-foot armored fish ruled the Late Devonian seas with razor-sharp bone blades instead ...
Phys.org / New synthesis strategy for (–)-gukulenin A reveals the chemistry behind its anticancer effects
A team of researchers from Yale University, U.S., successfully achieved the first stereoselective synthesis of the complex natural product (–)-gukulenin A (7), which exhibits notable cytotoxicity against ovarian cancer.
Phys.org / Not just stomata: Hidden water regulation mechanism could help crops survive drought
Cornell researchers have discovered a previously unknown way plants regulate water that is so fundamental it may change plant biology textbooks—and open the door to breeding more drought-tolerant crops.
Phys.org / Comet sparks scientific fascination, online furor over 'alien' origins
A flying piece of cosmic rock or an alien threat? Comet 3I/ATLAS is hurtling through our solar system and captivating scientists and internet users alike, even prompting Kim Kardashian to ask NASA for answers.
Medical Xpress / RNA editing study finds many ways for neurons to diversify
All starting from the same DNA, neurons ultimately take on individual characteristics in the brain and body. Differences in which genes they transcribe into RNA help determine which type of neuron they become, and from there, ...
Phys.org / The woman and the goose: A 12,000-year-old glimpse into prehistoric belief
A 12,000-year-old clay figurine unearthed in northern Israel, depicting a woman and a goose, is the earliest known human-animal interaction figurine. Found at the Late Natufian site of Nahal Ein Gev II, the piece predates ...
Tech Xplore / Nature-inspired hydrogel offers power-free thermal management
The poplar (Populus alba) has a unique survival strategy: when exposed to hot and dry conditions, it curls its leaves to expose the ventral surface, reflecting sunlight, and at night, the moisture condensed on the leaf surface ...
Phys.org / Cellular crowding in fruit fly embryos triggers a critical DNA reorganization, biologists find
After fertilization, embryos race through rapid cell divisions before slowing down to build specialized cells that will carry out distinct functions in the developing body—but the signals that trigger this shift have remained ...
Phys.org / Understanding bacteria's role in transforming steroids to pharmaceuticals
For decades, pharmaceutical companies have been using bacteria found in soil and water to chemically convert steroids into effective treatments for human diseases. One example is cortisol, which is used to treat asthma and ...
Medical Xpress / Type 1 diabetes cured in mice with gentle blood stem-cell and pancreatic islet transplant
A combination of blood stem cell and pancreatic islet cell transplant from an immunologically mismatched donor completely prevented or cured type 1 diabetes in mice in a study by Stanford Medicine researchers. Type 1 diabetes ...
