Senjokaku (千畳閣, Senjōkaku, lit. "pavilion of 1000 mats") is the common name of Hokoku Shrine. The name describes the spaciousness of the building, as Senjokaku is in fact approximately the size of one thousand tatami mats. The hall, which dates back to 1587, is located on a small hill just beside Itsukushima Shrine.

Toyotomi Hideyoshi, one of the three unifiers of Japan, commissioned Senjokaku for the purpose of chanting Buddhist sutras for fallen soldiers. The building was not yet completed when Hideyoshi died in 1598. As Tokugawa Ieyasu took power thereafter rather than the Toyotomi heirs, the building was never fully completed.

Senjokaku is strikingly sparse, lacking proper ceilings and a front entrance. In 1872, the incomplete building was dedicated to the soul of its founder, Toyotomi Hideyoshi, which remains its present-day religious function. Adjacent to Senjokaku stands a colorful five-storied pagoda originally built in 1407, predating the shrine itself.

The Secret Revolution in Battery Technology: 3-D Printing

"There's a revolution in battery technology hiding in plain sight," reports The Wall Street Journal. "The 3-D printing of batteries has the potential to put energy storage inside any device.

"This will enable lightweight and long-lasting consumer gadgets, long-range military drones and even nanoscale robots."
Almost all the innovations we regularly hear about — from cheaper, tougher electric-vehicle batteries to "Holy Grail" solid-state batteries — are about changing the chemistry of batteries. The promise of battery-tech 3-D printing (aka additive manufacturing) is simple: What if batteries could fill any available space, even structural elements of our gadgets, rather than always taking a rigid shape like a pouch or cylinder?

The new approach has obvious appeal. The entire airframe of a drone could be filled with energy storage for increased range. Smartglasses could have sleek battery-packed frames, so they look like everyday eyewear rather than "Revenge of the Nerds" props. One of the biggest advantages of 3-D printing is that it works with any battery, regardless of its cell chemistry. It could advance today's lithium-ion as well as emerging sodium-ion and solid-state tech... Some [startups] are trying to use 3-D printing to create efficiencies in existing battery manufacturing systems. A brave handful of startups are pursuing radical new designs and approaches. They're starting with defense applications, where cost and scale are less of an issue...

At Silicon Valley-based Sakuu... [r]ather than trying to 3-D-print whole batteries, the company is working on replacing one of battery manufacturing's biggest pain points, says Arwed Niestroj, Sakuu's chief operating officer, who is also a nuclear physicist and former head of Mercedes-Benz Research & Development North America. Existing battery assembly lines include football-field-long ovens for drying layers of material that have been dissolved in solvents. This requires a huge amount of energy and is a significant contributor to manufacturing costs, a big reason EV batteries aren't cheaper. Sakuu's process, under development for years, uses additive manufacturing to lay down key battery components without solvents, eliminating the need for ovens, says Niestroj.

Sakuu is currently working to commercialize this tech with a major battery manufacturer...

Jeremy Clarkson says he’s in remission from prostate cancer: ‘The doctors caught it early’

Former Top Gear host urges others to get tested after revealing diagnosis in fifth season of Clarkson’s Farm

Jeremy Clarkson says he is officially in remission from prostate cancer, less than a week after revealing he had an “aggressive” form of the disease in the final episodes of Clarkson’s Farm’s fifth season, which were filmed in 2025.

“I am without a doubt, officially, the world’s luckiest man,” said the former Top Gear presenter in an interview with the Sunday Times.

Ukraine war briefing: Dispute over second world war army unit threatens to divide Poland and Ukraine

Poland prime minister Donald Tusk ⁠hopes to ​defuse a ‘mistake’ from spiralling further; gasoline sales suspended in Crimea. What we know on day 1,580

A conflict between politicians in Poland ⁠and Ukraine is a strategic mistake that will harm both sides, Polish prime minister Donald Tusk ⁠has cautioned, ⁠as he seeks to ​defuse a rekindled dispute over events that occurred during the second world war. Polish president Karol Nawrocki on Friday ⁠stripped Volodymyr Zelenskyy of the country’s top honour, prompting three former Ukrainian presidents and other senior officials ⁠to return their state awards to Poland. Nawrocki revoked the Order of ​the White Eagle after ‌Zelenskyy angered many in Poland ‌by renaming a Ukrainian army unit after the Ukrainian Insurgent Army, ‌nationalists who massacred Poles during the second world war.

“Wading into a conflict between politicians in Poland and Ukraine ‌is a strategic mistake that will harm both sides: business-wise, geopolitically, and reputationally. And in politics, as we know, ​a mistake is worse than a crime,” Tusk wrote in a post on X. The pro-European Tusk was elected prime minister in 2023, after leading a coalition that defeated the nationalist Law and Justice party with which Nawrocki is aligned.

Zelenskyy, in ⁠an interview posted on X, said Ukraine and Poland cannot ​be “anything but ​partners and friends,” adding that a ​political struggle could end in a “very dangerous escalation”. “Our service members ​choose a ‌heroic name for ​their unit themselves, ​and as president and supreme commander-in-chief, I must support them,” he said. “Without Ukraine, no one will be able to defend Poland. It is simply impossible.”

Officials in Russia-occupied Crimea have suspended civilian gasoline sales as Ukraine increases attacks on fuel supplies. The Kremlin-appointed head of Crimea said Ukrainian strikes killed four people and wounded 28 others overnight. He said local petrol stations will now only sell fuel to government agencies. The Crimean peninsula has had periodic fuel shortages from Ukrainian strikes before, but the current crisis is the worst since its 2014 annexation. Social networks are filled with requests for fuel, and some speculators are selling gas at double the market price.

Zelenskyy described the attacks as part of Ukraine’s “long-range sanctions” against Russia’s energy infrastructure. Zelenskyy said in a statement that a Crimean oil depot, as well as an oil transport facility in Russia’s southern Krasnodar region were among the targets. “Russia understands only strength, and our long-range strength is certainly working for peace,” he said. Separately, overnight Russian strikes in eastern Ukraine killed three people.

Ukraine has in recent months also stepped up drone attacks on energy facilities in Russia, striking targets deep behind the frontlines. Last week, it hit a large refinery in Moscow twice. Ukraine says the attacks are aimed at denting oil revenues that Russia uses to fund the war. Some petrol stations in Russia, the world’s third-biggest oil producer, introduced fuel rationing this month. Fuel exports have been banned since April. Energy Intelligence, a US-based energy research firm, said earlier this month that about a third of Russian oil refining capacity had gone offline because of Ukrainian strikes.

Why the dig of the century is happening underneath Notre Dame

Why the dig of the century is happening underneath Notre Dame. More than a year after France's famed Notre Dame reopened, an archaeological exploration going thousands of years into the history of Paris has begun just metres below the cathedral's ground floor. (France)
