South Korea is developing autonomous robots to recover the remains of soldiers killed in the Korean War.

The excavations will take place in Arrowhead Ridge, a former battlefield inside the demilitarized zone (DMZ) that bisects the Korean Peninsula.

The droids will use AI to scan underground for bodies of soldiers still missing from the war, which began in 1950 when North Korean communist forces invaded the capitalist south.

Many emerging technologies rely on high-quality lasers. Laser-based LiDAR sensors can provide highly accurate scans of three-dimensional spaces, and as such are crucial in applications ranging from autonomous vehicles to geological mapping technologies and emergency response systems. High-quality lasers are also a key part of the high-speed, high-volume data centers that are the backbone of the internet.

When assessing the quality of a laser, researchers look to the noise in a laser’s frequency, or the number of times the laser’s light wave toggles in each second. Low-quality, “noisy” lasers have more random variations in those toggles, making them useless for systems that are meant to return accurate measurements or convey densely packed information.

At present, lasers with adequately low frequency noise are bulky, expensive and an impractical choice for mass manufacturing. Penn Engineers have set out to solve this problem with a device called a “phase noise filter” that can turn low-cost, compact lasers into those suitable for LiDAR and more.

In addition to snow, 75 million people will wake up to below freezing temperatures Saturday. For many cities it will be colder than it was on Christmas Day.

North Korean dictator Kim Jong Un was once filmed chatting to two identically dressed lookalikes — escalating wild conspiracies that a body double was recently used to claim he is alive and well.

Footage from July 2017 discovered by the Sun shows the Hermit Kingdom’s leader with the doppelgangers as he showed off a new missile.

The pair appear the same height and size, with identically cut hair shaved at the back and sides, and wearing suits perfectly matching the one worn by their leader, the Sun noted.

Blue Origin has never been much for marketing. Now, as it has won a large NASA contract, it is opening up a merchandise store.

As France makes the wearing of facial masks mandatory on public transport, it’s trialling new AI technology to check whether passengers are complying. The software, made by French startup Datakalab, is being trialed first in Paris, and will only generate anonymous statistical data.

In the future, people getting ready for a flight — and fearing impending jet lag — might fit an assortment of additions into their carry on: masks, gloves, and maybe a medicinal mushroom hailed for delivering animalistic sex drive.

That’s because a new study suggests that a synthetic form of cordycepin, a compound found in a medicinal fungus with a reputation for keeping bedroom doors closed, may help ease the pain of jet lag.

A University of Saskatchewan (USask) research team has uncovered how bats can carry the Middle East respiratory syndrome (MERS) coronavirus without getting sick—research that could shed light on how coronaviruses make the jump to humans and other animals.

Coronaviruses such as MERS, Severe Acute Respiratory Syndrome (SARS), and more recently the COVID19-causing SARS-CoV-2 virus, are thought to have originated in bats. While these viruses can cause serious and often fatal disease in people, for reasons not previously well understood, bats seem unharmed.

“The bats don’t get rid of the virus and yet don’t get sick. We wanted to understand why the MERS virus doesn’t shut down the bat immune responses as it does in humans,” said USask microbiologist Vikram Misra.
