An international research team, including scientists at Australia’s national science agency, CSIRO, has used a new observation technique to discover the brightest extragalactic pulsar known, and it could even be the most luminous one ever found.

First discovered in 1967, pulsars are remnants of massive stars and offer researchers potential applications in areas like random number generation and guidance systems for spacecraft.

The research team used the ASKAP radio telescope, owned and operated by CSIRO, to apply a new method of seeking out pulsars...

Atrial fibrillation, the most common cardiac rhythm abnormality, has been linked to one-third of ischemic strokes, the most common type of stroke. But atrial fibrillation is underdiagnosed, partly because many patients are asymptomatic.

Artificial intelligence-enabled electrocardiography (ECG) was recently shown to identify the presence of brief episodes of atrial fibrillation, and the ability of an AI-enabled ECG algorithm to predict atrial fibrillation up to 10 years before clinical diagnosis has been confirmed in a population-based study conducted by Mayo Clinic researchers.

A new population-based study from Mayo Clinic now offers evidence that the algorithm can help identify patients at greater risk of cognitive decline...

The new technology could make at-home diagnosis of diseases faster and more affordable. A University of Minnesota Twin Cities research team has developed a new microfluidic chip for diagnosing diseases that uses a minimal number of components and can be powered wirelessly by a smartphone. The innovation opens the door for faster and more affordable at-home medical testing.

The researchers’ paper is published in Nature Communications, a peer-reviewed, open access, scientific journal published by Nature Research...

For the past thirty years, the star β Pictoris has fascinated astronomers because it enables them to observe a planetary system in the process of formation. It is made up of at least two young planets, and also contains comets, which were detected as early as 1987. These were the first comets ever observed around a star other than the Sun.

Now, an international research team headed by Alain Lecavelier des Etangs, CNRS researcher at the Institut d’Astrophysique de Paris (CNRS/Sorbonne Université)1, has discovered 30 such exocomets and determined the size of their nuclei1, which vary between 3 and 14 kilometres in diameter...
