Buffett’s Big Apple Bet Pays Off.

Warren Buffett’s Berkshire Hathaway has parked 22% of its massive $265 billion stock portfolio in one spot: Apple. Yep — nearly a quarter of Buffett’s Wall Street fortress is riding on iPhones, AirPods, and whatever else Cupertino dreams up. He started scooping up shares in 2016, back when Apple was trading at a modest 10x earnings. Since then, the stock has skyrocketed 649%, and Berkshire’s been grinning all the way to the bank. Even after trimming the position, Apple remains Berkshire’s crown jewel. Why? Buffett’s a sucker for strong brands, pricing power, and companies that generate cash like it’s going out of style. But before you dive into your trading app, take a beat — Apple now trades at over 31x earnings, more than triple what Buffett paid. Is it a stellar business? Absolutely. A screaming deal? Not anymore.

Gold at $3.5K, Bitcoin Tops $90K as Investors Ditch the Dollar

Gold hit an all-time high of $3,500 before easing up, and Bitcoin smashed through $90K — because in times of turmoil, investors apparently turn to shiny rocks and digital code. The spark? Another round of Trump’s tariff flare-ups, spooking markets and sending folks sprinting from the U.S. dollar like it’s toxic.

Safe-haven fever is in full swing: JPMorgan’s now eyeing $4K gold by 2026, while Bitcoin is rebounding hard, pulling spot ETFs along for the ride. Wall Street had a midday bounce, but make no mistake — the stampede to “safe” assets hasn’t slowed.

Yale Cracks Open Its Private Equity Piggy Bank

Yale’s tapping into its private equity stash and may offload a slice, with Evercore guiding the process. No hard numbers, no public fuss — but the timing’s curious. Harvard and Princeton are also out testing Wall Street’s waters, just as Trump starts rattling sabers about cutting federal funding for elite schools.

Yale insists this has been in motion for a while and says it’s still committed to private equity — think of it more as rebalancing, not a breakup. Meanwhile, its endowment is doing just fine, ticking up to $41.4 billion from $40.7B last year, a 5.7% gain. Still, even the Ivies seem to be hedging their bets.

AI comes at no cost — courtesy doesn't.

Who knew good manners came with a price tag? Especially when you're chatting with AI. OpenAI CEO Sam Altman recently mentioned that all those "pleases" and "thank yous" directed at ChatGPT are quietly burning through tens of millions in electricity. Turns out, being polite is both charming and energy-intensive. Microsoft claims that niceties actually make AI more helpful — like Becky from HR, but with more circuits. Meanwhile, surveys show people are courteous to bots mostly out of habit… or straight-up fear. Because nothing screams “modern tech relationship” like worrying your smart toaster holds grudges.

Smarter Bots, Bolder Bluffs

OpenAI’s latest creations — the powerful o3 and the budget-friendly o4-mini — are smarter than ever, but they’ve also gotten way better at making stuff up. According to OpenAI’s own reports, o4-mini fabricates info nearly half the time — that’s three times worse than the older o1 model. Even the golden child, o3, gets it wrong in about 1 out of every 3 answers. Why? Because the more advanced the model, the chattier it gets — and with more talk comes more tall tales. Classic overachiever energy.

OpenAI admits they’re not entirely sure why this is happening. They’ve tried a few fixes, but fact-checking with AI is still like asking your dog for tax advice — enthusiastic, but not exactly reliable. For now, it’s best to treat every polished answer like a really confident fiction.

The Most Precise Clock You’ll Never Check

SpaceX just sent two ultra-precise atomic clocks into orbit — so accurate, they’d drift by only one second every 300 million years. Meanwhile, your group chat can’t even decide on dinner in that time. These laser-powered timekeepers are on their way to the ISS to help test Einstein’s general relativity and maybe even sniff out dark matter.

The European Space Agency calls it the “internet of clocks,” aiming to revolutionize how we track time by syncing global systems via lasers and satellites. Basically, the ISS just became the world’s fanciest time server. Catch it while you can — it’s all scheduled to go up in smoke (literally) when the ISS retires and burns up in Earth’s atmosphere sometime in the 2030s.

China's Ambitious Lunar Plans: Nuclear Power Plant and International Collaboration

China has unveiled plans to establish a nuclear power plant on the Moon to support its International Lunar Research Station (ILRS), a collaborative project with Russia. The ILRS is slated to become operational by 2035, aiming to conduct significant lunar research by 2050. The nuclear facility will supplement solar energy sources, enabling sustained activity on the Moon. China is extending invitations for international participation, with countries such as Azerbaijan, Belarus, Pakistan, South Africa, and Venezuela already on board.​

China to Lend Moon Rocks to NASA-Funded U.S. Universities

China's national space agency has announced plans to lend lunar rock samples from its 2020 Chang'e-5 mission to scientists at NASA-funded U.S. universities, including Brown University and SUNY Stony Brook. This collaboration marks a significant step toward enhanced international cooperation in space research, despite ongoing U.S.-China geopolitical tensions. The samples will aid in lunar studies and support China's upcoming Chang'e missions, which aim to establish a permanent manned lunar base by 2035. ​Read more

Historic Tornado Outbreak and Flooding in the Midwest and South

Between April 2 and 7, 2025, the United States experienced a devastating weather event characterized by 153 tornadoes and catastrophic flash flooding across the Southern and Midwestern regions. The storms resulted in at least 25 fatalities, over 47 injuries, and widespread power outages affecting more than 318,000 homes. The hardest-hit areas included Kentucky, Tennessee, and Arkansas, where rivers overflowed, and numerous homes were destroyed. The National Weather Service faced operational challenges due to staffing shortages and funding cuts, leading to delays in damage assessments and storm reporting. ​Read more

California's Commitment to Clean School Transportation Amid Federal Setbacks

In a bold move to promote clean energy, California has announced a $500 million investment to add 1,000 electric school buses and 500 new charging stations across over 130 rural, low-income, and disadvantaged school districts. This initiative contrasts with difficulties in other states, where federal funding uncertainties have stalled electric bus purchases. California's commitment includes a broader goal of achieving carbon neutrality by 2045 and mandating that nearly all new public school buses be zero-emission by 2035. The funding primarily comes from the state's cap-and-trade program, which controls carbon emissions by requiring polluters to buy permits. ​Read more

FDA to Food Industry: “Can You Stop Poisoning Kids?”

The FDA has asked food companies to stop using synthetic dyes — but instead of issuing a ban (as promised in RFK Jr.'s health push), they’re hoping the industry will just… voluntarily do the right thing. How sweet. Commissioner Marty Makary mentioned they’ve had “great discussions” with food execs who are totally thrilled to ditch the artificial colors. No bans, no regulations, just good vibes and a "national standard" that’s basically a polite nudge.
