AI tool spots hidden heart disease using routine electrocardiogram data

With the help of artificial intelligence (AI), an inexpensive test found in many doctors’ offices may soon be used to screen for hidden heart disease.

Structural heart disease, including valve disease, congenital heart disease, and other issues that impair heart function, affects millions of people worldwide. Yet in the absence of a routine, affordable screening test, many structural heart problems go undetected until significant function has been lost.

“We have colonoscopies, we have mammograms, but we have no equivalents for most forms of heart disease,” says Pierre Elias, assistant professor of medicine and biomedical informatics at Columbia University Vagelos College of Physicians and Surgeons and medical director for artificial intelligence at NewYork-Presbyterian.

Humans beat AI at international math contest despite gold-level AI scores

Humans beat generative AI models made by Google and OpenAI at a top international mathematics competition, despite the programs reaching gold-level scores for the first time.

Neither model scored full marks—unlike five young people at the International Mathematical Olympiad (IMO), a prestigious annual competition where participants must be under 20 years old.

Google said Monday that an advanced version of its Gemini chatbot had solved five out of the six set at the IMO, held in Australia’s Queensland this month.

In a first, transmon qubit achieves a coherence time of one millisecond

A team of researchers in Finland has set a new world record for how long a quantum bit, known as a qubit, can hold onto its information.

They have pushed the coherence time of a superconducting transmon qubit to a full millisecond at best, with a median time of half a millisecond. That might sound brief, but in the world of quantum computing, it’s a massive improvement that could change the game.

Longer coherence times mean qubits can run more operations and quantum computers can perform more calculations before errors start to appear.

Next-Generation Proteomics of Brain Extracellular Vesicles in Schizophrenia Provide New Clues on the Altered Molecular Connectome

Extracellular vesicles (EVs) are tiny membranous structures that mediate intercellular communication. The role(s) of these vesicles have been widely investigated in the context of neurological diseases; however, their potential implications in the neuropathology subjacent to human psychiatric disorders remain mostly unknown. Here, by using next-generation discovery-driven proteomics, we investigate the potential role(s) of brain EVs (bEVs) in schizophrenia (SZ) by analyzing these vesicles from the three post-mortem anatomical brain regions: the prefrontal cortex (PFC), hippocampus (HC), and caudate (CAU). The results obtained indicate that bEVs from SZ-affected brains contain region-specific proteins that are associated with abnormal GABAergic and glutamatergic transmission.

Alien world found? Massive ‘Super-Earth’ Kepler-139f discovered beyond our solar system—All you need to know

Kepler-139 f is a Neptune-like exoplanet that orbits a G-type star. The mass of this planet is 36 times that of Earth, which takes 355 days to complete one orbit of its star. It was discovered by NASA scientists in 2025.
