Pieces of 'Atlantis': 16th century Dominican church revealed in drought (Drone footage)

A severe drought in Mexico has revealed a 400-year-old Dominican church that has remained almost completely intact despite spending decades submerged under water.

Drone footage of the submerged church sitting in the Benito Juarez Dam in Jalapa del Marquez, Oaxaca, was captured on Monday.

Amazing Laswitan in Cortes, Surigao del Sur Philippines

The Laswitan Falls and Lagoon is actually a unique 20-foot rock formation located near the shore in Cortes. This geological feature creates three natural basins so that when the surf becomes high, the huge waves would flow and spill into the main basin on the other side, thus creating a waterfall effect.

The lagoon below the rock formation is so huge in that it can fit up to 200 people – maybe even more! Tourists visiting the place can dip in these pools and get themselves splashed by the sea water coming from the other side. The lagoon has a deep part which swimmers can enjoy but there is also a shallow area that other people can dip in.

Student accidentally creates rechargeable battery that lasts 400 years

Lab accident leads to the discovery of a battery that can be used for hundreds of years

Researchers at the University of California, Irvine (UCI) have discovered a way to design a battery so it doesn’t lose its charge after years of use. The team found that by using a gold nanowire in electrolyte gel rather than lithium, a battery could withstand 200,000 charging cycles and only lose 5% of its capacity.

After playing around in the university’s lab, it was doctoral student Mya Le Thai who initially made the discovery, one which could lead to rechargeable batteries that last up to 400 years. This means longer-lasting laptops and smartphones, and fewer lithium-ion batteries accumulating in landfills.

Originally, the researchers were experimenting with nanowires for potential use in batteries, but found that over time, the fragile, thin wires would break down and crack after multiple charging cycles. It was on a whim that Thai coated a set of gold nanowires in manganese dioxide and a Plexiglas-like electrolyte gel.

“She started to cycle these gel capacitors, and that’s when we got the surprise,” said chair of the university’s chemistry department, Reginald Penner. “She said, ‘this thing has been cycling 10,000 cycles and it’s still going.’ She came back a few days later and said ‘it’s been cycling for 30,000 cycles.’ That kept going on for a month.”

Thai’s breakthrough is incredible, considering the average laptop battery lasts 300 to 500 charging cycles. The nano-battery developed at UCI survived 200,000 cycles in three months, meaning it could extend the life of the average laptop battery by about 400 years.

Of course, the researchers realized the amount of gold nanowire needed to create this battery would drive up prices, so they suggested nickel could be a substitute for mass production.

Either way: not bad for messing around in a laboratory.
