Dr. Hyekyoung Choi and Min Ju Yun’s research team from the Energy Conversion Materials Research Center, Korea Electrotechnology Research Institute (KERI), has developed a technology that can increase the flexibility and efficiency of a thermoelectric generator to the world’s highest level by using “mechanical metamaterials” that do not exist in nature. The research results were published in Advanced Energy Materials.

In general, a material shrinks in the vertical direction when it is stretched in the horizontal direction. It is like when you press a rubber ball, it flattens out sideways, and when you pull a rubber band, it stretches tightly.

The amount of transversal elongation divided by the amount of axial compression is Poisson’s ratio. Conversely, mechanical metamaterials, unlike materials in nature, are artificially designed to expand in both the horizontal and vertical directions when it is stretched in the horizontal direction. Metamaterials have a negative Poisson’s ratio.

The Tesla Cybertruck was spotted on the beach, driving through ocean water in the Gulf of Mexico just a week from deliveries.

Tesla claimed a while ago that the Cybertruck would be able to float. Although the truck did not completely enter the water in this instance, we have no idea if the automaker has prepared the pickup to travel through bodies of water.

Beach driving is popular, and all-wheel-drive or four-wheel-drive vehicles are suitable for this kind of travel. Drivers also need to air down their tires in order to prevent their car or truck from digging into the sand, but a vehicle cannot be too heavy, either, as it will sink into the beach. The highest gross vehicle weight on most drive-on beaches is 10,000 pounds.

SYDNEY, Nov 21 (Reuters) — Some residents of a remote Papua New Guinea island were preparing on Tuesday to evacuate from the vicinity of an erupting volcano that shot a cloud of ash into the sky forcing the cancellation of some flights.

Teams had been sent to the Mount Ulawun area on New Britain island to coordinate an evacuation after it began erupting on Monday, state broadcaster NBC PNG reported senior disaster management official Clement Bailey as saying.

Flights from the island’s Hoskins airport had been cancelled, the broadcaster said, adding that the volcano was still erupting.

A first-of-its-kind study led by the University of California, Irvine has revealed a new culprit in the formation of brain hemorrhages that does not involve injury to the blood vessels, as previously believed. Researchers discovered that interactions between aged red blood cells and brain capillaries can lead to cerebral microbleeds, offering deeper insights into how they occur and identifying potential new therapeutic targets for treatment and prevention.

The findings, published online in the Journal of Neuroinflammation, describe how the team was able to watch the process by which stall in the brain capillaries and then observe how the hemorrhage happens. Cerebral microbleeds are associated with a variety of conditions that occur at higher rates in older adults, including hypertension, Alzheimer’s disease and ischemic stroke.

“We have previously explored this issue in , but our current study is significant in expanding our understanding of the mechanism by which cerebral microbleeds develop,” said co-corresponding author Dr. Mark Fisher, professor of neurology in UCI’s School of Medicine. “Our findings may have profound clinical implications, as we identified a link between red blood cell damage and cerebral hemorrhages that occurs at the capillary level.”

CANBERRA, Australia (AP) — An eruption of Papua New Guinea’s tallest volcano that raised regional tsunami fears subsided Tuesday, but thick ash still billowed into the sky and coated roofs and palm trees nearby.

One of the South Pacific nation’s most active volcanoes, Mount Ulawun erupted on Monday, spewing ash as high as 15 kilometers (50,000 feet).

Papua New Guinea’s Geohazards Management Division said while the eruption had been downgraded since Monday from the maximum alert level, there were no signs that it was ending.

According to a KSLTV article, “veterinary laboratories in several states are investigating an unusual respiratory illness in dogs, and encouraging people to take basic precautions to keep their pets healthy as veterinarians try to pin down what’s making the animals sick.”

The “outbreak” of this respiratory illness is currently in three states: Oregon, Colorado, and New Hampshire. Research is being done right now in the Granite State.
