The James Webb Space Telescope has found a giant exoplanet in the habitable zone of Alpha Centauri A, a sunlike star in the Alpha Centauri system, according to findings in the Astrophysical Journal Letters. The exoplanet, tentatively named Alpha Centauri Ab, is comparable to Saturn in mass and size, although it has not been confirmed with follow-up observations. "If confirmed, the potential planet seen in the Webb image of Alpha Centauri A would mark a new milestone for exoplanet imaging efforts," says astrophysicist Aniket Sanghi.

A study published in Science Advances reveals that a 500-year-old Inca khipu, a knotted cord that recorded information, made from human hair rather than llama wool was likely crafted by a commoner rather than a noble. Isotope analysis of the hair shows a diet typical of commoners, challenging the belief that khipus were exclusively made by elite male bureaucrats.

California Institute of Technology researchers have achieved a major breakthrough in quantum memory extension by converting quantum electrical signals from superconducting qubits into mechanical sound waves, according to a study in Nature Physics. Using a chip-based mechanical oscillator, this approach preserves quantum states up to 30 times longer than traditional qubits. The method slows energy loss and reduces interference, significantly enhancing the duration that quantum information can be reliably stored for future processing.

A study published in Frontiers in Mammal Science reveals that North American river otters might be ecosystem engineers, based on an analysis of their scat. Researchers found that otters primarily eat crabs and finfish, which are often infested with parasites. The study suggests that otters help control parasite populations, benefiting the ecosystem, and can serve as disease sentinels to warn of potential public health threats.

Weight-loss drugs such as Ozempic and Wegovy may reduce lean mass, affecting muscle strength and organ size, especially the liver, according to a study published in Cell Metabolism. The study shows that certain muscles became weaker, posing potential concerns for adults older than 60, with researchers emphasizing the need for human studies to assess health risks.

Pickleball-related injuries among children surged in 2024, with facial injuries being the most common, according to a study published in the American Journal of Emergency Medicine. The study, which analyzed emergency department visits from 2014 to 2024, found that younger children are at higher risk for lacerations, while older children are more prone to joint injuries.

Missouri University of Science and Technology has secured a $19.8 million grant to lead the NSF's Center for Synthetic Organic Electrochemistry, partnering with 13 institutions to advance electrosynthesis for safer, cost-effective chemical manufacturing. "My research team and colleagues throughout the country and world are working to make electrochemistry inventions more accessible in chemical and pharmaceutical manufacturing," said Shelley Minteer, the project's lead investigator.

October 30 - November 1, 2025
STEM students across the globe are invited to showcase their research and compete for awards at the 2025 International Forum on Research Excellence (IFoRE), powered by Sigma Xi. IFoRE is going virtual in 2025, which means no travel expenses and easy access for all presenting students. Students who participate in the virtual event will get unique opportunities to network with peers and professionals in their field, gain valuable research presentation experience, and discover future opportunities with school programs and employers. All competing students will be eligible for monetary awards in their discipline and education level. Learn more at experienceIFoRE.
