Pills and syringe, for article on fentanyl vaccine human trials

Scientists preparing first human trials for vaccines that block the effects of deadly opioids

Fentanyl vaccines are heading into their first human trials, with Phase 1 testing set to begin in early 2024 at Columbia University. Developed by researchers at the University of Montana and University of Washington, the vaccines train the immune system to grab fentanyl molecules in the bloodstream, like a sponge, before they can reach the brain. That means no high, and no slowed breathing, which is what makes overdoses fatal. The team is especially focused on people in the first two years of recovery, when relapse risk is highest. If it works, this could become a powerful new tool in a crisis that has demanded every bit of compassion and ingenuity we can offer.

Model of a heart, for article on muvalaplin Lp(a) cholesterol

World-first drug lowers genetic form of “bad cholesterol” by up to 65%

Muvalaplin, a new pill from researchers at Monash University, lowered a dangerous genetic form of cholesterol by up to 65% in just two weeks during early trials. The drug targets lipoprotein(a), or Lp(a), a stickier cousin of LDL cholesterol that’s been called a “silent killer” because diet, exercise, and statins can’t touch it. Roughly one in five people worldwide carry elevated Lp(a), inherited risk they’ve long been told there’s nothing to do about. That muvalaplin works as a simple oral tablet, not an injection, could make it widely accessible if larger trials succeed. For global heart health, it’s a hopeful sign that even risks written into our DNA may not be the final word.

Virtual reality or cyberspace concept: digital human or robot head, for article on brain-computer interface

Paralyzed woman able to ‘speak’ through digital avatar in world first

A digital avatar has given a paralyzed woman her voice back — speaking at 78 words per minute, more than five times faster than the eye-tracking system she relied on before. Ann, who had a brainstem stroke 18 years ago, worked with UCSF researchers to train an AI to read brain signals from electrodes resting on her brain’s surface. The avatar speaks in a voice reconstructed from her wedding video, complete with facial expressions like smiles and frowns. There are real limits — the system still misreads words about a quarter of the time — but for millions living with ALS, locked-in syndrome, or severe stroke, this points toward a future where losing a voice no longer means losing a self.

Dam, for article on Klamath River dam removal

Work begins along California-Oregon border on largest dam removal project in U.S. history

Klamath River restoration is now the largest dam removal effort in U.S. history, reopening more than 400 miles of river to salmon once the last three dams come down. But the real story is what comes next: members of the Karuk, Yurok, and other tribal nations spent five years hand-gathering seeds from nearly 100 native plant species, and roughly 17 billion of those seeds will be sown along the freed riverbanks over the coming decade. Tribal ecological knowledge is shaping every phase, woven together with western science. For Indigenous communities worldwide fighting to restore ancestral waters, the Klamath offers a powerful template — proof that rivers, and the cultures rooted in them, can be brought back to life.
