The world's first human trial of a drug that can regenerate teeth will begin in a few months, less than a year on from news of its success in animals. This paves the way for the medicine to be commercially available as early as 2030. The trial, which will take place at Kyoto University Hospital from September to August 2025, will treat 30 males aged 30-64 who are missing at least one molar. The intravenous treatment will be tested for its efficacy on human dentition, after it successfully grew new teeth in ferret and mouse models with no significant side...

High purchase prices are a major barrier to the wider adoption of electric vehicles. A significant portion of this cost comes from expensive batteries. However, in recent years, automakers have been employing an advanced manufacturing technique known as gigacasting. This method helps offset the high cost of batteries, simplifies production, and reduces the weight of EVs. Nissan will follow Tesla, and several other carmakers like Toyota, Hyundai, and Ford, in adopting this technology. The brand aims to reduce the costs of EV parts by 10% and slash weight by 20%, Automotive News reported. Nissan's EVs using gigacasting are expected to...

Remember the “New Atheists”? They were a big deal 15 or so years ago, bashing irrationality and superstition in bestselling books like “The God Delusion,” “The End of Faith” and “God Is Not Great.” Some of them ultimately ended up as believers, others turned to ayahuasca, and Richard Dawkins recently admitted to being a “cultural Christian.” He still doesn't believe in the big J.C., but acknowledges his worldview was shaped in a Christian context. In a similar way, I've always been a cultural libertarian. A son of the Mountain West, my traditional conservatism is heavily dosed with a “leave me...

THE HAGUE, Netherlands — The chief prosecutor of the International Criminal Court said Monday he is seeking arrest warrants for Israeli and Hamas leaders, including Israeli Prime Minister Benjamin Netanyahu, in connection with their actions during the seven-month war. Karim Khan said that he believes Netanyahu, his defense minister Yoav Gallant and three Hamas leaders—Yehya Sinwar, Mohammed Deif and Ismail Haniyeh—are responsible for war crimes and crimes against humanity in the Gaza Strip and Israel.

Swiss researchers have developed a solar energy method using synthetic quartz to achieve temperatures above 1,000°C for industrial processes, potentially replacing fossil fuels in the production of materials like steel and cement. Instead of burning fossil fuels to reach the temperatures needed to smelt steel and cook cement, scientists in Switzerland want to use heat from the sun. The proof-of-concept study uses synthetic quartz to trap solar energy at temperatures over 1,000°C (1,832°F), demonstrating the method’s potential role in providing clean energy for carbon-intensive industries. A paper on the research was published on May 15 in the journal Device. The...

There's a right name for the "Woke" ideology, and it's critical constructivism. Critical constructivist ideology is what you "wake up" to when you go Woke. Reading this book, which originally codified it in 2005, is like reading a confession of Woke ideology. Let's talk about it.

President Biden has challenged former President Donald Trump to not one, but TWO presidential debates in the most cringe-worthy way possible. Not only does Biden want to circumvent the Commission on Presidential Debates, which would have suggested 3 debates, but he wants to hold the first one much earlier than usual — BEFORE the Democratic National Convention. Glenn has a theory as to why this is: Is he giving the Democratic Party enough time to REPLACE him if his polls keep dropping? Glenn, Pat, and Stu also review some of Biden’s ridiculous rule proposals and Trump’s quick response to the...

It's rarely great news when an area gets blanketed in volcanic ash – but University of Barcelona researchers have discovered it has a rare combination of useful properties, which make it remarkably useful as an energy storage medium. We've written a number of times about super-cheap thermal energy storage, and a number of other times about highly efficient heat batteries operating at super-high temperatures. The cheapest of these 'brick toasters' use the most abundant of materials, and the most efficient can handle extraordinarily high temperatures using materials like liquid tin and carbon materials – but volcanic ash, as it turns...

Two Korean research institutes are designing a space solar power satellite project with the aim of providing approximately 1000 TWh of electricity to the Earth per year. The 95 gigawatts of nuclear in the US generates 800 terawatt hours per year. Spaced based solar at 120 gigawatts would generate 1000 terawatt hours. This is an improved proposed Korean Space Solar Power Satellite (K-SSPS) project. It is a conceptual design of the satellite, its end-of-life disposal method, and a first pilot system and experiment. The proposed system would use 4,000 sub-solar arrays measuring 10 meters × 270 meters and comprising thin...

It was set to be the world's first flight test for an aerospike rocket engine, but the MIRA I prototype crashed on takeoff before the most innovative part of its propulsion system could fire. Undeterred, Polaris is building two bigger prototypes. The MIRA I, from German aerospace startup Polaris Raumflugzeuge, was traveling at approximately 105 mph (169 km/h) during takeoff when a "landing gear steering reaction" plus a side wind caused a "hard landing event," rendering the space plane inoperable and it's fiberglass airframe damaged beyond repair. Its subsystems remained mostly intact – however, rather than attempt to repair the...

While we don't like to talk ill of the dead, new physiological analysis has found that the king of the dinosaurs was not so smart after all. It upends previous research that last year likened the brain and neuronal composition of the Tyrannosaurus rex to that of a primate. It's been a rough year or two for the long extinct dinosaur. First, we questioned their teeth, finding that those iconic chompers could very much have been smaller and hidden behind lips, and now an international team of paleontologists, behavioral scientists and neurologists have concluded that the T. rex wasn't smarter...

Charles Hall, a former weather observer at Nellis Air Force Base, shares his incredible story of encountering the Tall Whites, an extraterrestrial species working with the US military. These chalk-white aliens, standing up to 9 feet tall, have been influencing human technology and evolution for decades. Charles's friendship with a Tall White known as "The Teacher" led him to discover hidden alien facilities and the shocking truth about their presence on Earth. Uncover the secrets of the Tall Whites, from their advanced scout crafts to their underground bases, and explore the startling implications of their alliance with the US government...

One of the driest growing seasons in decades has decimated crops and left millions hungry. A prolonged dry spell in southern Africa in early 2024 scorched crops and threatened food security for millions of people. The drought has been fueled in large part by the ongoing El Niño, which shifted rainfall patterns during the growing season. Impact on Rainfall and Agriculture From late January through mid-March, parts of Southern Africa received half or less of their typical rainfall, according to researchers at the Climate Hazards Center (CHC) at the University of California, Santa Barbara. February 2024 was especially dry. The...

FIRST CITY IN CANADA TO REQUIRE A QR CODE, TO EXIT THE CITY. îles de la Madeleine, Québec. Island of Madeleine, QC

Police say a task force investigating a multimillion-dollar gold heist at Pearson airport last year has arrested multiple people, laid 19 related charges and interrupted a "large quantity of firearms" intended for import into Canada in connection with the case. Peel Regional Police announced the results of their year-long probe into the daring theft at a Wednesday morning news conference alongside a representative from the the U.S. Alcohol, Tobacco and Firearms Bureau. One of the men arrested, a 54-year-old man from Brampton, is an Air Canada employee. An arrest warrant has also been issued for another man who was also...

Cities are playing a lead role in cutting greenhouse gas emissions to meet the Paris Agreement’s science-based, internationally accepted target of limiting global heating to 1.5°C. Every city wanting to take effective action to mitigate climate change and adapt to its effects needs a climate action plan (CAP) – an evidence-based roadmap for delivering its fair share of emissions cuts and strengthening its resilience. That’s why the development and implementation of a Paris Agreement-aligned CAP is a requirement for every C40 city. C40 is a global network of nearly 100 mayors of cities at the forefront of climate leadership, and...

IM motors has decided that semi solid-state batteries are ready for prime time. In an omen of what Western automakers will need to contend with, it's now launched a futuristic luxury coupe with a next-gen battery pack and crab-walking capability. The high-density lithium batteries we enjoy today were an absolute technological revolution. They blew rechargeable nickel-cadmium and nickel-metal-hydride batteries out of the water, offering such a leap in energy storage by weight and volume that suddenly all sorts of things became possible.

The world’s tallest prison standing at 300-foot is being built in Chinatown, New York City, sending residents into an uproar. The 40-floor tower which will house 1,000 prisoners will be located on the grounds of the former Manhattan Detention Complex. Known to locals as The Tombs, the old prison will be demolished in order to make way for the “jail scraper”. The destruction of the detention complex has caused major disruption for nearby residents, with heavy dust and loud noise creating chaos.

One of the more common memes that I’ve seen white supremacists spread around recently has been “diversity is a code word for white genocide”. The concept here is that diversity is only promoted in white nations, and that the end goal is to eliminate white people altogether by flooding all white countries with non-white people until there are no white people left. Well, guess what, white supremacists? That’s exactly right. Diversity IS about getting rid of white people, and that’s a good thing.
