Tech Xplore / Worms navigate narrow paths faster than wide ones. These findings could inform robot design
You might naturally expect a wide, open path to be faster and easier to navigate than a narrow one, just as birds fly freely through the open sky, cars move quickly on empty roads, and a wide hallway seems easier when trying ...
Phys.org / Interstellar travel V: Warp drives, wormholes, and halo drives
Welcome back to our series on Interstellar Travel, where we look at the many proposals made for sending missions to the stars since the dawn of the Space Age. In our first installment, we examined how Cold War-era developments ...
Phys.org / JWST reveals likely Type II supernova from when universe was only 2 billion years old
Astronomers using the James Webb Space Telescope have identified one of the most distant exploding stars ever confirmed. The supernova, SN 2023aeaf, was found at a redshift of 3.195—so far away that its light has been traveling ...
Phys.org / Physicists finally put Feynman's path integral to the test
For nearly 80 years, physicists have relied on a thought experiment created by Richard Feynman to predict how quantum particles behave. For the first time, researchers in China have tested this trick directly in the lab.
Medical Xpress / A 'one-two punch' against aggressive breast cancer could offer an alternative to chemotherapy
Triple-negative breast cancer (TNBC) has a frustrating ability to adapt. Although this aggressive form of breast cancer can initially respond well to chemotherapy, cancer cells often find ways to survive, allowing the disease ...
Phys.org / Caught right-handed: Mystery of coiling snake embryos explained
An international team led by Canadian researchers has found evidence explaining why snake embryos form a curious spiral. This ability to coil as embryos enables snakes to hatch with the longest bodies of all vertebrates.
Phys.org / Rocky Mountain find reveals new funnel-web spider far from its Northwest relatives
Researchers at the University of Idaho have identified a new species of spider in the mountains of northern Idaho and given it a name that pays tribute to the university itself: Hexura vandal. The spider belongs to a small ...
Tech Xplore / Quantum-tunneling field-effect transistor overcomes barriers to integrated-circuit chip development
The next generation of microelectronics relies on radical improvements in transistor switching performance to advance computing power. However, conventional semiconductor technology has hit a physical limit known as the "Boltzmann ...
Medical Xpress / Scientists in France pinpoint why STING pathway hasn't been harnessed for cancer therapy yet
Deep within the cellular landscape, a quiet failure was taking place, impeding a potentially successful form of cancer treatment. For years, scientists hoped an essential part of the innate immune system that detects foreign ...
Phys.org / JWST may solve a 20-year mystery behind a rule-breaking gamma-ray burst
Astronomers may have finally solved the mystery behind a nearly two-decade-old cosmic explosion that seemed to break the rules of physics. The energy output of a powerful gamma-ray burst, GRB 061201, discovered in 2006, did ...
Phys.org / UK and Ireland face greatest risk from rare tropical cyclones reaching Europe
Europe is no stranger to powerful windstorms, but some storms capable of causing serious damage have an unusual origin. Tropical cyclones can occasionally travel north from lower latitudes and reach Europe, where they can ...
Tech Xplore / Worn traffic signs fool AI vision systems, exposing autonomous-driving risks
In computer vision and robotics, ensuring that AI systems remain reliable under real-world conditions is a growing challenge. Deep neural network (DNN)-based vision systems are increasingly used in safety-critical applications ...
