Scientists using sound recordings from underwater nuclear bomb detectors have discovered the distinct song of a previously unknown population of pygmy blue whales in the Indian Ocean.
Summary: A new deep neural network can accurately predict a healthy person’s brain age based on EEG data collected from a sleep study.

A study shows that a deep neural network model can accurately predict the brain age of healthy patients based on electroencephalogram data recorded during an overnight sleep study, and EEG-predicted brain age indices display unique characteristics within populations with different diseases.
The accelerating effort to understand the mathematics of quantum field theory will have profound consequences for both math and physics.

**A team of researchers affiliated with institutions in Singapore, China, Germany and the U.K., has developed an insect-computer hybrid system for use in search operations after disasters strike. **They have written a paper describing their system, now posted on the arXiv preprint server.
Because of the frequency of natural disasters such as earthquakes, fires and floods, scientists have been looking for better ways to help victims trapped in the rubble–people climbing over wreckage is both hazardous and inefficient. The researchers noted that small creatures such as insects move much more easily under such conditions and set upon the task of using a type of cockroach as a searcher to assist human efforts.
The system they came up with merges microtechnology with the natural skills of a live Madagascar hissing cockroach. These cockroaches are known for their dark brown and black body coloring and, of course, for the hissing sound they make when upset. They are also one of the few wingless cockroaches, which made them a good candidate for carrying a backpack.

Google claims that it has developed artificial intelligence software that can design computer chips faster than humans can.
The tech giant said in a paper in the journal Nature on Wednesday that a chip that would take humans months to design can be dreamed up by its new AI in less than six hours.
The AI has already been used to develop the latest iteration of Google’s tensor processing unit chips, which are used to run AI-related tasks, Google said.
By grinding up nanotubes and dipping them in special solvents, the team showed it’s possible to generate enough current to run important electrochemical reactions, and maybe one day to power super-small devices.
As more kids go down the ‘deep, dark tunnel’ of long Covid, doctors still can’t predict who is at risk.
“She was a completely healthy, active kid and this just totally changed her life,” her mother, Sara Dardis, said. “So obviously, Covid is real and it’s real for kids. It needs to be taken seriously.”
Kate’s story makes clear that long Covid is not an adults-only phenomenon. Numbers are hard to come by, but more children and adolescents are experiencing chronic symptoms after Covid even as the pandemic ebbs in the U.S., say doctors at the few clinics devoted to caring for them. Although the disease has played out in ways that differ between adults and children, long Covid is posing the same mystery in kids as in adults.

Researchers at Purdue University, Indiana, have developed a method to transform ordinary clothes into battery-free wearables that are waterproof and resistant to laundry. These smart fabrics can be powered wirelessly through a flexible, silk-based coil sewn on the textile.
