Easter Bombing Verdict
A Sri Lankan court sentenced 15 men to life in prison yesterday for their roles in the 2019 Easter Sunday bombings, which killed more than 260 people and wounded roughly 500. The verdict follows a nearly five-year trial.
The coordinated suicide bombings targeted three churches and three luxury hotels during Easter services and celebrations across the island nation (see timeline and visual guide). Two local militant groups inspired by the Islamic State group were accused of carrying out the attacks; none of those believed to have directly participated survived. In 2021, authorities charged 25 people with 23,270 counts, including murder and conspiracy to commit terrorism. Authorities also arrested a former intelligence chief in February, alleging he had prior knowledge of, and conspired in, the bombings; he remains in custody.
Sri Lanka's Catholic Church has argued the bombings were part of a broader conspiracy extending beyond those identified as perpetrators, though it has not provided evidence supporting the claim.
Meet the Fire Amoeba
Scientists have discovered an amoeba capable of living in extreme heat, once thought inhospitable to complex life, according to a study published yesterday.
The single-celled organism, dubbed the “fire amoeba,” was discovered in a geothermal spring at California’s Lassen Volcanic National Park. Researchers observed the amoeba continuing to replicate in cultures heated to 145 degrees Fahrenheit—five degrees hotter than scientists had previously seen complex life tolerate. The amoeba withstood temperatures up to 158 degrees by changing shape and forming a protective layer. These adaptations are shared with simpler life-forms that lack a membrane-bound nucleus and can survive at temperatures up to nearly 252 degrees. See a side-by-side illustration of complex and simple life here.
The fire amoeba could offer clues for developing heat-resilient crops and drugs, and scientists believe some complex life-forms may survive at even higher temperatures.

The Pentagon’s Got Their Eye on This Tech
The US military were early backers of some of the most important innovations of our time, from the internet to drones.
Now? It’s flying cars. The military invested $142M into a company building five-seater fleets. But the military’s most covert ops need smaller, personal aircraft. That spells opportunity for Doroni. Their H1-X personal aircraft could open the skies to all members of the military. Its SOUL.AI platform is so intuitive, pilots need just 25 hours of training to operate.
With 600+ preorders already and first deliveries planned for 2028, this new future could come faster than you think. Now’s your chance to get in at the private stage. Just don’t wait. Invest in Doroni at $3.30/share by October 22.*

MIT Dethrones Princeton
The Massachusetts Institute of Technology unseated Princeton as the nation’s top college yesterday, ending the Ivy League school's 15-year run leading US News & World Report's annual rankings. See the full list here.
This year’s rankings introduced a criterion comparing graduates’ earnings by major four years after college with those who studied the same major nationwide. The measure includes only federal financial aid recipients, part of an effort to minimize the impact preexisting wealth and family connections could have on post-college earnings. It replaces a metric that measured graduates’ federal loan debt.
The rankings have faced scrutiny over their methodology and reliance on universities’ self-reported data. Dozens of prestigious law and medical schools—including Harvard, Yale, and Stanford—stopped submitting data in 2022 and 2023. Columbia University was the only top 100 undergraduate institution that did not submit data directly this year; it ranked No. 12.
Higher education faces a broader demographic squeeze, with lower birth rates projected to contribute to a 13% decline in enrollment by 2041 (see graphs).
