Astronomers have confirmed the youngest known exoplanet ever discovered: Elias 2-24 b, a Jupiter-mass world less than a million years old, still embedded in the gas and dust disk around its young star 450 light-years from Earth.^[1]

Stanford physicists have recorded the first direct observation of quantum jumps of sound in a mechanical resonator, capturing individual phonons making sudden energy-state transitions in real time—a breakthrough with potential applications for quantum computing error correction.^[2]

The U.S. Federal Reserve raised its benchmark interest rate by 25 basis points to 3.75%-4%, its first increase since 2023, in a unanimous vote aimed at combating inflation driven by elevated energy prices.^[3]

South Korea hosted the first-ever Korea–Central Asia Summit in Seoul, where President Lee Jae Myung and the leaders of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan adopted a 30-year cooperation framework targeting critical minerals, energy, and supply chains.^[4]

Researchers at Washington University School of Medicine have discovered lymph node-like immune structures in skull bone marrow that act as rapid first responders against brain cancer, a finding that could lead to new treatments for glioblastoma and neurodegenerative diseases.^[5]

Stanford researchers have created a virtual biotech company powered by 37,000 AI scientist agents that identified a cancer therapy target which later received FDA breakthrough therapy designation, validating the platform's drug discovery capabilities.^[6]

University of Delaware researchers have developed a pocket-sized cosmic ray detector called CosmicWatch that costs roughly $100 and can reveal the invisible stream of muons passing through Earth, with the device now being used in major physics experiments and balloon missions.^[7]

The Bank of Japan is holding its monetary policy meeting September 17-18, with markets widely expecting a rate increase to 1.25%, which would be the country's highest interest rate in more than three decades.^[8]

New research published in Science shows that global wind energy may remain relatively stable even as climate change shifts storm tracks poleward, as opposing effects of warming on atmospheric circulation currently cancel each other out.^[9]

OpenAI announced it will introduce a public reporting framework to share unexpected AI behavior with external researchers, following calls from industry leaders including Anthropic's CEO for greater third-party oversight of AI development.^[10]
