New artificial intelligence tool can accurately identify cancer

Exclusive: algorithm performs more efficiently and effectively than current methods, according to a studyDoctors, scientists and researchers have built an artificial intelligence model that can accurately identify cancer in a development they say could speed up diagnosis of the disease and fast-track patients to treatment.Cancer is a leading cause of death worldwide. It results in about 10 million...

A supermassive black hole and its jet, all in a single picture

In May 2022, the Event Horizon Telescope (EHT) team released the first-ever radio image of M87's central black hole. It was a stunning revelation based on observations made using a worldwide array of radio telescopes. Recently, they re-released a newer, sharper image of the black hole's "ring of light."

The science of standup: can you train someone to be funny?

The founders of Melbourne’s Steam Room program believe scientists can make their work more accessible through humour. Will their hypothesis prove true?Get our weekend culture and lifestyle emailFive scientists walk into a theatre and try standup for the first time. Does hilarity ensue?Yes, according to the producers of the Steam Room – a program in which comedians teach a team of scientists...

Thank the Lords someone is worried about AI weapons | John Naughton

While politics as usual dominates the Commons, thankfully a few people from the upper chamber are thinking about the big pictureThe most interesting TV I’ve watched recently did not come from a conventional television channel, nor even from Netflix, but from TV coverage of parliament. It was a recording of a meeting of the AI in weapons systems select committee of the House of Lords, which was...

Seal’s mystery ability to tolerate toxic metal could aid medical research, say scientists

The Juan Fernández fur seal, once thought extinct, can ingest cadmium without ill effects – though no one knows howA creature that humans came very close to obliterating now offers hope that we may be able to find ways to tackle one of the most pernicious environmental poisons, say scientists.Their research has revealed that one of the world’s most isolated aquatic mammals, the Continue...

New viruses related to both giant viruses and herpesviruses

Metagenomic data from Tara Oceans on marine plankton has enabled the discovery of a major group of DNA viruses found abundantly from the equator to the poles: mirusviruses. These viruses play a role in regulating plankton by infecting a considerable number of single-cell organisms at any given time.

Researchers use genomes of 241 species to redefine mammalian tree of life

Research led by a team of scientists from the Texas A&M School of Veterinary Medicine and Biomedical Sciences puts to bed the heated scientific debate regarding the history of mammal diversification as it relates to the extinction of the non-avian dinosaurs. Their work provides a definitive answer to the evolutionary timeline of mammals throughout the last 100 million years.

Previously unknown intercellular electricity may power biology

Researchers have discovered that the electrical fields and activity that exist through a cell's membrane also exist within and around another type of cellular structure called biological condensates. Like oil droplets floating in water, these structures exist because of differences in density. Their foundational discovery could change the way researchers think about biological chemistry. It could...

New research redefines mammalian tree of life

Scientists from around the globe are using the largest mammalian genomic dataset in history to determine the evolutionary history of the human genome in the context of mammalian evolutionary history. Their ultimate goal is to better identify the genetic basis for traits and diseases in people and other species.
