Mysterious, Ancient Radio Signals Keep Pelting Earth. Astronomers Designed an AI to Hunt Them Down.
Sudden shrieks of radio waves from deep space keep slamming into radio telescopes on Earth, spattering those instruments' detectors with confusing data. And now, astronomers are using artificial intelligence to pinpoint the source of the shrieks, in the hope of explaining what's sending them to Earth from -- researchers suspect -- billions of light-years across space. Usually, these weird, unexplained signals are detected only after the fact, when astronomers notice out-of-place spikes in their data -- sometimes years after the incident. The signals have complex, mysterious structures, patterns of peaks and valleys in radio waves that play out in just milliseconds. That's not the sort of signal astronomers expect to come from a simple explosion, or any other one of the standard events known to scatter spikes of electromagnetic energy across space. Ever since the first one was uncovered in 2007, using data recorded in 2001, there's been an ongoing effort to pin down their source.
Mysterious radio signals from billions of light-years away can now be detected in real time
A PhD student in Australia has developed an automated system to detect, in real time, mysterious radio pulses emanating from the deep universe. The fleeting signals known as fast radio bursts (FRBs) have baffled scientists since they were first discovered in 2007 by a team poring through archival data. Since then, there have been numerous other instances of their detection โ though what exactly causes them remains a mystery. The latest breakthrough could be a huge leap forward for scientists' ability to understand the nature of fast radio bursts, allowing them to be captured in detail the moment they reach Earth.

Artificial Intelligence used to detect fast radio bursts
Scientists have developed an automated system that uses artificial intelligence (AI) to detect and capture fast radio bursts (FRBs) in real-time. FRBs are mysterious and powerful flashes of radio waves from space, thought to originate billions of light years from the Earth, said researchers from Swinburne University of Technology in Australia. They last for only a few milliseconds or a thousandth of a second and their cause is one of astronomy's biggest puzzles. Astronomical Society, has already identified five bursts -- including one of the most energetic ever detected, as well as the broadest. Wael Farah from Swinburne University of Technology trained the on-site computer at the Molonglo Radio Observatory in Australia to recognise the signs and signatures of FRBs, and trigger an immediate capture of the finest details seen to date.
When is an animal a person? Neuroscience tries to set the rules
Chicks born with a bit of quail brain spliced in. Rats with their brains synced to create a mind-meld computer. For two days in June, some of neuroscience's most extraordinary feats were debated over coffee and vegetarian food at the Institute for Research in Cognitive Science in Philadelphia. The idea wasn't to celebrate these accomplishments but to examine them. Martha Farah, a cognitive neuroscientist at the University of Pennsylvania, assembled a group of scientists, philosophers and policy-makers to discuss the moral implications for the animals involved.
A Superadditive-Impairment Theory of Optic Aphasia
Mozer, Michael C., Sitton, Mark, Farah, Martha J.
Farah (1990) has proposed an alternative class of explanations involving partial damage to multiple pathways. We explore this explanation for optic aphasia, a disorder in which severe perfonnance deficits are observed when patients are asked to name visually presented objects, but surprisingly, performance is relatively nonnal on naming objects from auditory cues and on gesturing the appropriate use of visually presented objects.
