Notre Dame Cathedral in Paris is set to reopen on December 8, marking a significant milestone in its restoration after the devastating 2019 fire. As part of the renovation, acoustics researcher Brian Katz has been studying the sonic qualities of the cathedral, aiming to recreate its original reverberant sound. The cathedral’s acoustics were severely impacted…
Researchers at the University of Iowa and University Medical Center Utrecht have made a significant breakthrough in cancer treatment by incorporating volumetric-modulated arc therapy (VMAT) delivery capabilities into the MR-linac. This innovation could improve plan quality and efficiency, reduce patient discomfort, and make MRI-guided treatments more accessible to patients. The team demonstrated that VMAT deliveries…
Mathematicians Ben Green and Mehtaab Sawhney have made a groundbreaking discovery in the field of number theory, proving that there are infinitely many prime numbers that can be written as the sum of squares of other prime numbers. This breakthrough, which uses a powerful tool called the Gowers norm, has significant implications for our understanding…
A groundbreaking discovery in Kenya has shed new light on the lives of our ancient ancestors. The fossilized footprints of two ancient species, Homo erectus and Paranthropus boisei, have been found at the Koobi Fora site, dating back 1.5 million years. This remarkable find provides the first direct evidence of different archaic human species coexisting…
China’s market regulator has launched an antitrust investigation into Nvidia’s acquisition of Mellanox, a move that comes amid escalating tensions between the US and China over key technologies, including artificial intelligence and semiconductors. The probe is seen as a retaliatory measure by China following Washington’s restrictions on semiconductor manufacturers, including Nvidia, from selling their most…
A recent study by the High Energy Stereoscopic System (HESS) collaboration has confirmed the existence of a “cooling break” in the energy spectrum of cosmic ray electrons and positrons at around 1 TeV. The research, published in Physical Review Letters, suggests that the origins of these particles are still hotly debated, with possible explanations including…
Archaeologists have unearthed clay cylinders in Syria, dated to 4,400 years ago, inscribed with the earliest known alphabetic writing system. The discovery, made in the Umm el-Marra tomb, has sparked excitement among scholars, who believe it may rekindle the idea of the location of the earliest alphabet. The symbols, which correspond to sounds, are similar…
Researchers at University College London have created the thinnest pasta ever made, measuring just 370 nanometers thick. This innovation was achieved by mixing flour with formic acid and using electrospinning to create nanofibers. The new pasta is not intended for human consumption but has potential applications in biodegradable bandages and wound dressings. Forecast for 6…
Researchers at the Massachusetts Institute of Technology (MIT) have developed a new transistor made from semiconducting vertical nanowires of gallium antimonide (GaSb) and indium arsenide (InAs). This innovation could lead to ultra-low-power electronics, ideal for applications such as the Internet of Things (IoT) and artificial intelligence. The new transistor uses electrons tunneling through an energy…
A recent phenomenon has been observed in the popular conversational AI platform ChatGPT, where users discovered that the chatbot freezes or crashes when asked about specific names, including David Mayer, Brian Hood, Jonathan Turley, Jonathan Zittrain, David Faber, and Guido Scorza. After investigating, it appears that these individuals may have requested their information to be…
