It’s a frustrating limitation of 3D printing: Printed objects must be smaller than the machine making them. Huge machines are impractical for printing large parts because they take up too much space and require excessive time to print. Now, a new material reported in ACS Applied Materials & Interfaces can be used to 3D print […]
Researchers have used artificial intelligence to detect Vietnam War-era bomb craters in Cambodia from satellite images – with the hope that it can help find unexploded bombs. The new method increased true bomb crater detection by more than 160 percent over standard methods. The model, combined with declassified U.S. military records, suggests that 44 to […]
Machine learning can be used to track surges in interest in health topics on popular online comment boards, like Reddit, according to a new study conducted during the COVID-19 outbreak by researchers in the Perelman School of Medicine at the University of Pennsylvania (Penn Medicine). Such insight could help public health officials better understand and […]
Nuclear bomb tests during the Cold War may have changed rainfall patterns thousands of miles from the detonation sites, new research has revealed. Scientists at the University of Reading have researched how the electric charge released by radiation from the test detonations, carried out predominantly by the US and Soviet Union in the 1950s and […]
Earth-based experiments on iron-sulfur alloys thought to comprise the core of Mars reveal details about the planet’s seismic properties for the first time. This information will be compared to observations made by Martian space probes in the near future. Whether the results between experiment and observation coincide or not will either confirm existing theories about […]
Earth may have been far more oxygen-rich early in its history than previously thought, setting the stage for the evolution of complex life, according to new research by scientists at the University of Alberta and the University of Tartu in Estonia. The study provides evidence for elevated oxygen levels 2 billion years ago and flies […]
Exercise and physical therapy often are recommended to help people who have arthritis. Both can strengthen muscle — a benefit that also can reduce joint pain. But building muscle mass and strength can take many months and be difficult in the face of joint pain from osteoarthritis, particularly for older people who are overweight. A […]
Selective powder sintering for 3D printing has recently become an increasingly affordable solution for manufacturing made-to-order elements of almost any shape or geometry. This technique involves heating a bed of powder (such as polyamide, PA12) to just below its melting point, using an IR light source to selectively melt a cross section of the powder, […]
