The impact of 63.5 million cubic meters of rock hitting the fjord released forces large enough to be registered globally. The seismic waves that cascaded across the planet were recorded by sensor stations worldwide and were equivalent in energy to a magnitude 5.4 earthquake. The sloshing water within the fjord established a 66-second long-period seiche, ..

Like any other manufactured chip, the wiring that connects the quantum dots is locked into place during the chip’s manufacture. Since different error correction schemes require different connections among the qubits, this forces us to commit to specific error-correction schemes during manufacturing. If a better scheme is developed after a chip is made, it’s probably ..

The actual shipwrecks of the HMS Erebus and the HMS Terror were not found until 2014 and 2016, respectively. Thanks to the cold water temperature, lack of natural light, and the layers of silt covering many of the artifacts, the ship and its contents were in remarkably good condition. Even some of the windowpanes were ..
Pollen isn’t the only allergen impacted by climate change. Increased humidity, heat, and flooding also create ideal conditions for mold to flourish in places where it was previously rare. That can cause mold allergies to flare up, especially in the aftermath of climate-driven disasters like hurricanes, or for patients living in older buildings, basement units, ..
The bottom line: Astronauts likely won’t exceed Artemis II’s distance from Earth on most lunar landing missions, but it’s conceivable that on some occasions, circumstances will align to propel a crew a little beyond the 252,756-mile mark. The sure bet will come when someone finally takes aim at Mars. “Big disappointment” Haise, the only Apollo ..
The US Space Force released a list Friday of a dozen companies working on Space-Based Interceptors for the Pentagon’s Golden Dome initiative, a multilayer defense system to shield US territory from drones and ballistic, hypersonic, and cruise missile attacks. The roster of Golden Dome Space-Based Interceptor (SBI) contractors, some of which were previously reported, includes ..
On top of that, when analyzing the beaks, the team noticed a distinct pattern. The wear wasn’t uniform. The right edge of the jaw was consistently more worn down, chipped, and scratched than the left. The team concluded this asymmetry wasn’t an accident but a proof of lateralized behavior. It’s a tendency we observe in ..
Shortly after their discovery, carbon nanotubes seemed to be a material wonder. There were metallic and semiconducting forms; they were tiny and incredibly light; and they could only be broken by tearing apart chemical bonds. The ideas for using them seemed endless. But then the reality of working with them set in. It was hard ..
[embedded content] The gravitational constant, affectionally known as “Big G,” is one of the most fundamental constants of our universe. Its value describes the strength of the gravitational force acting on two masses separated by a given distance—or if you want to be relativistic about it, the amount a given mass curves space-time. Physicists have ..
