Polar bears begin living in abandoned buildings in a remote island.

Kokh’s photos are a welcome sight, as we’re often shown images of polar bears who are struggling. But here, we are able to see these incredible creatures lounging on the grass or peering out from windows to see what Kokh is up to. This thrilling opportunity to see the polar bears is something that Kokh will not soon forget. He and his traveling companions covered over 1,200 miles of the coast in a sailboat, exploring the untouched landscape.

Their original destination to photograph polar bears—Wrangle Island—turned out to be a bust. Though the island is famous for its bears, they simply weren’t there when the adventurers landed. Instead, they were treated to something that was perhaps better—and certainly more unexpected.

A new study in an animal model of aging indicates a potential reason for why women who have early menopause or other genetic conditions affecting the reproductive system are more prone to develop cardiovascular disease, diabetes, and dementia.

The new study, led by researchers from the University of Pittsburgh and UPMC and published in the journal Aging Cell, found that disrupting a process called meiosis in C. elegans reproductive cells caused a decline in the worms’ health and triggered an accelerated aging gene signature similar to that of aging humans.

“This study is exciting because it’s the first direct evidence that manipulating the health of reproductive cells leads to premature aging and a decline in healthspan,” said senior author Arjumand Ghazi, Ph.D., associate professor of pediatrics, developmental biology, and cell biology and physiology at Pitt and UPMC Children’s Hospital of Pittsburgh. “The implications of this finding are profound: It suggests that the status of the reproductive system is important not simply to produce children, but also for overall health.”

Identification of molecularly defined gut-to-brain and downstream brain circuits participating in nausea and retching induced by enterotoxins and chemotherapeutic drugs in mice suggests that food poisoning and chemotherapy recruit similar circuit modules to initiate defensive responses.

Researchers have developed an alternative positioning system that is more robust and accurate than GPS, especially in urban settings.

An alternative positioning system that is more robust and accurate than GPS, especially in urban settings has been developed by researchers of Delft University of Technology, Vrije Universiteit Amsterdam, and VSL. The working prototype that demonstrated this new mobile network infrastructure achieved an accuracy.

So people in wheelchairs can enjoy the great outdoors. bigsmile

For years, many people with disabilities couldn’t access the great outdoors with ease like able-bodied people. Now, with this all-terrain wheelchair, they can in Georgia.

Judging by pictures of the system alone, the Type 625E short-range air defense system (SHORAD) looks to be an 8×8 vehicle-mounted self-propelled anti-aircraft gun and surface-to-air missile system of sorts. For Zhuhai, the Type 625E was sporting a pixelated desert camouflage scheme and, of course, its stacked armament. Its turret with a sizable Gatling-style cannon is especially difficult to ignore, with the barrel pointed directly at the camera in some pictures taken during the show, and it is believed to be of the 25mm variety, but that detail remains unconfirmed. Land-based close-in defense Gatling-style guns of this type are becoming increasingly prominent in China’s weapons portfolio.

The vehicle also comes equipped with four canisterized missiles fitted to either side of the turret. The exact type of missile used on this system is unclear, but the general configuration would suggest that they could be FB-10 short-range types. Reportedly designed by the China Aerospace Long-March International (ALIT) company, FB-10 traces back to at least 2014 and appears to have entered service with the People’s Liberation Army at least on some level the following year. China then displayed the FB-10 at the Zhuhai Air Show in 2016 mounted on a 6×6 truck chassis as opposed to the Type 625E’s 8×8 vehicle base.

An FB-10A variant was then unveiled in 2021 during the Egypt Defense Exhibition in a similar configuration to the 2016 showcase, and its chassis was this time confirmed to be a Dongfeng Mengshi 6×6 light tactical vehicle. There also appears to be an FB-20 air-defense missile system, though confirmed information about this derivative is even thinner. FB-series missiles can purportedly engage low-flying air targets at a maximum range of over 6 miles (10 km) and reach an altitude of anywhere between 49 feet (15 m) to roughly 3 miles (5,000 m).
