Tech Xplore / A stair-climbing robot that catches itself when it falls
SUTD researchers have developed a reinforcement-learning-based safety system that teaches a stair-traversing service robot to brace itself mid-fall, addressing one of the biggest barriers to deploying autonomous robots on ...
Phys.org / Quantum entanglement provides a new framework for understanding chemical bonding
Chemical bonding is one of the central organizing principles of the microscopic world. It determines how atoms combine and thereby governs a wide range of physical and chemical properties of quantum systems across many length ...
Phys.org / Settling down vs. settling: New study proves being single beats a bad relationship
While society often assumes that finding a romantic partner is the ultimate key to happiness, tracking relationship changes over time reveals a distinctly different reality. A massive longitudinal study proves that individuals ...
Medical Xpress / From dish to brain: Researchers chart human glial cell maturation
A new study published in Nature Communications shows that human glial progenitor cells are a promising and safe cell product for transplantation. The research also defines the transcriptional and epigenetic signatures of ...
Phys.org / Turtles finally have a place in the tree of life thanks to an X‑ray study of South African fossils
The origin of turtles has always been a bit of a puzzle for scientists who study the evolution of animals. To this day, where they fit in the tree of life remains a highly debated topic.
Phys.org / Red dwarf stars detected 'eating' Earth-like planets
Astronomers have found some of the strongest evidence yet that stars can swallow their own planets. A new study, published in Monthly Notices of the Royal Astronomical Society, supports the long-held belief that young stars ...
Phys.org / Mineral clues in Gale Crater track ancient Mars climate change
While NASA imagery has shown evidence of ancient rivers and lakes on Mars that transitioned to dry dunes, uncertainty remains over the timing of the environmental changes that may have contributed to these shifts.
Phys.org / New ammonia-making method could upend one of industry's dirtiest processes
As our world's population grows, so does the demand for ammonia—a key ingredient in fertilizer. The International Renewable Energy Agency estimates that ammonia production must quadruple by 2050 to feed the increase in global ...
Phys.org / Silver nanoparticles enable assembly of a theorized, previously unobserved crystal metallic structure
Using finely tuned nanoscale building blocks, researchers from Brown University and the University of Michigan College of Engineering have stabilized a fleeting structural phase of matter that had been predicted theoretically ...
Phys.org / What a toothless, two-legged crocodile cousin reveals about life before dinosaurs dominated
In the Triassic, the modern animals we know were just beginning to diversify into a menagerie of forms and body plans that rhyme with the lifestyles of extinct and living animals better known to the public, but nested in ...
Phys.org / Fake predator eyes scare off seabirds until they learn they're not real
In Danish fisheries, fish-eating seabirds are a menace. They often swoop down and feed on fish trapped in nets, which can hit profits and also sometimes lead to the accidental death of the birds. So scientists deployed an ...
Phys.org / Spider silk-inspired process turns corn protein into tougher plastic-like material
When it comes to technology and innovation, we have a lot to thank Mother Nature for. Learning from the natural world has led to a range of useful products, including Velcro, self-cleaning paint, and ultra-strong body armor. ...
