Neutrons are among the basic building blocks of matter. As long as they are part of a stable atomic nucleus, they can stay there for arbitrary periods of time. However, the situation is different for free neutrons: They decay—after about 15 minutes, on average.
It took nearly three years for workers at a dinosaur museum in Heyuan, Guangdong province to restore a nest of 11 dinosaur eggs unearthed near a local bridge.
“Every piece of information about the dinosaur eggs is well recorded, waiting for future uncovering,” said Huang Zhiqing, deputy director of the collection and research department at the Heyuan Dinosaur Museum.
The nest of eggs is just a small part of their kind in the museum. There are nearly 20,000 dinosaur egg fossils on display at the museum since the first dinosaur egg fossil was dug up in Heyuan in 1996.
A database developed by the Global Dam Watch (GDW) consortium is set to transform the global understanding of dams and reservoirs.
Future fusion power plants will require good plasma confinement to sustain reactions and generate energy. One way to contain plasma for fusion reactions is to use a tokamak, a device that applies magnetic fields to “bottle” plasma. However, magnetic islands, a type of instability in the plasma, can destroy the confining magnetic field if they grow large enough.

Dark oxygen could have been discovered for the first time in history: Experts are worried about what could we do know.
Researchers have made a groundbreaking discovery that human olfactory perception can detect changes in odors within just a single breath, challenging the previously held view that our sense of smell is slow.
By utilizing a sniff-triggered device precise to 18 milliseconds, they demonstrated that people can discern between two different odors in sequences as short as 60 milliseconds—faster than a blink.
Understanding Olfaction: Speed and Sensitivity.
Still, damaging waters need not be a the result of a named storm or involve storm surge to destroy property, or spur flood warnings miles from the ocean. Florida’s flat, low-lying landscape, its limestone geology and its development patterns combine to present an ongoing and sometimes unpredictable threat from the wet stuff that experts fear will become more apparent with increasing temperatures and moisture.
“Virtually the entire state of Florida is a coastal plain,” said Tom Missimer, a hydrogeology professor emeritus at Florida Gulf Coast University’s College of Engineering in Fort Myers, who has been studying water movement for more than half a century. “When we get a large rainfall event, there’s not a lot of storage in the ground to absorb the new water coming in.”
OpenAI scientists have designed MLE-bench — a compilation of 75 extremely difficult tests that can assess whether a future advanced AI agent is capable of modifying its own code and improving itself.
