This study has identified the anterior cingulate cortex (ACC) as a key area in the brain responsible for sensory hypersensitivity in autism spectrum disorders. Utilizing a mouse model with a Grin2b gene mutation, heightened neural activity and connectivity in the ACC was observed. Suppressing this hyperactivity normalized the sensory hypersensitivity, offering new insights into treatment options

- How cockroaches spread around the globe to become the pest we know todayapnews.com How cockroaches spread around the globe to become the pest we know today
A new study tracks how cockroaches spread around the globe to become the survival experts we know today.
They’re six-legged, hairy home invaders that just won’t die, no matter how hard you try.
Cockroaches are experts at surviving indoors, hiding in kitchen pipes or musty drawers. But they didn’t start out that way.
A new study uses genetics to chart cockroaches’ spread across the globe, from humble beginnings in southeast Asia to Europe and beyond. The findings span thousands of years of cockroach history and suggest the pests may have scuttled across the globe by hitching a ride with another species: people.
“It’s not just an insect story,” said Stephen Richards, an assistant professor at Baylor College of Medicine who studies insect genes and was not involved with the study. “It’s an insect and humanity story.”

- Blue Origin launches 1st crewed spaceflight since August 2022 (video)www.space.com Blue Origin launches 1st crewed spaceflight since August 2022 (video)

The mission, known as NS-25, sent six people on a brief trip to suborbital space today (May 19).
Blue Origin's nearly two-year human spaceflight drought is over.
Jeff Bezos' aerospace company launched its NS-25 mission today (May 19), sending six people — including the United States' first-ever Black astronaut candidate — on a brief trip to suborbital space aboard its New Shepard rocket-capsule combo.
It was Blue Origin's first space tourism launch since August 2022. That previous mission went well, but the company's next flight, an uncrewed research jaunt that launched a month later, did not: New Shepard suffered a serious anomaly, causing the destruction of the first-stage booster. (The capsule landed safely under parachutes.)
New Shepard was grounded for more than a year while Blue Origin investigated the September 2022 accident, which the company eventually traced to a thermo-structural failure in the nozzle of the rocket's single engine. The vehicle returned to action this past December on an uncrewed flight and is now fully back, with another human mission under its belt.
