The Phase 1/2 trial data from Janssen Research & Development covered hundreds of myeloma patients. Based on preliminary trial data, the FDA has granted it “Breakthrough Therapy” designation.
Fusion energy just cleared a barrier scientists have been chasing since the 1950s — producing more energy from a reaction than was needed to trigger it. Researchers at Lawrence Livermore National Laboratory achieved this by blasting tiny hydrogen fuel capsules with lasers until they released roughly 20 percent more energy than the lasers delivered. The result doesn’t mean fusion power plants are imminent; enormous engineering challenges remain between this laboratory milestone and a working grid. But it does confirm that fusion’s central promise is physically real — and that gives scientists, investors, and policymakers something genuinely new to build on.
Oregon Governor Kate Brown has announced today that she has issued pardons to everyone caught possessing up to an ounce of marijuana prior to its legalization in 2016.
Glioblastoma patients now have the most promising new treatment in nearly three decades, after a personalised vaccine more than doubled five-year survival rates in a large international trial. The vaccine works by extracting proteins from a patient’s own tumour and combining them with their white blood cells, training the immune system to recognise and destroy the cancer — with benefits seen even among those traditionally considered hardest to treat. If regulators approve it, this could signal a new era of personalised immunotherapy for cancers that have long resisted every available option.
Removing four dams on California’s Klamath River will reopen more than 300 miles of salmon habitat, making it the largest river restoration project ever attempted. Federal regulators approved the $500 million plan unanimously, capping decades of advocacy led by the Yurok, Karuk, and Hoopa Valley tribes, whose cultures and food systems have been bound to these fish since long before the first dam went up. “The Klamath salmon are coming home,” Yurok Chairman Joseph James said after the vote. As drought reshapes the American West, letting a major river run free again offers a powerful template for healing watersheds, honoring Indigenous leadership, and rethinking what aging infrastructure owes the living world.
The federal carbon price floor was a charge of CAN$40 per ton on carbon emissions in 2021, and this fee will rise to CAN$170 per ton by 2030.
The 17-million-member Church of Jesus Christ of Latter-day Saints now supports a bill that codifies the recognition of same-sex marriages performed in any state by other states and the federal government.
In tests performed on rats at the University of Houston, the vaccine was shown to be effective at keeping one of the deadliest street drugs from reaching the brain, while not producing any significant side effects.
Colorado’s Natural Medicine Health Act goes further than any previous U.S. state psychedelic law, removing criminal penalties for personal use of psilocybin, DMT, ibogaine, and mescaline — and building a licensed therapy clinic system alongside it. The FDA has already granted psilocybin “breakthrough therapy” status for treatment-resistant depression, giving this reform unusual clinical credibility. Colorado helped pioneer cannabis legalization in 2012, and advocates are watching to see whether psychedelic reform follows a similar path outward. For people who haven’t found relief through conventional treatments, this law opens a genuinely new door.
The age-adjusted prevalence of dementia declined from 12.2 percent of people over age 65 in 2000 to 8.5 percent of people over age 65 in 2016—a nearly one-third drop from the 2000 level, according to a new RAND Corporation study.
