Alzheimer’s Drugs Clear the Plaques but Leave Patients No Better Off The brain scans look unambiguous. After 18 months of treatment, the amyloid plaques that riddle the brains of early Alzheimer’s patients are visibly reduced, sometimes dramatically so. The drug is doing exactly what it was designed to do: hunting down those sticky protein deposits and clearing them away. So why aren’t the patients getting better? ...

Sperm Whales Have Vowels and the Grammar to Go With Them Off the coast of Dominica, in water deep enough to swallow a skyscraper, a female sperm whale draws breath and dives. Somewhere below, she clicks. Not randomly. Not reflexively. She clicks in sequences with internal structure: rhythm, duration, a vowel quality she actively controls and that her neighbours recognise. Until recently, we had no idea ... Read more The post Sperm Whales Have Vowels and the Grammar to Go With Them appeared first on Wild Science.

How Scientists Learned to Read Information Encoded in Darkness Inside Light Inside a beam of light, there are places where the light simply isn’t. Not dim, not scattered, not absorbed. Absent, a void of zero intensity threading through the beam like a knotted vein of darkness. These are phase singularities: points where the electromagnetic phase becomes undefined, where the wave collapses into nothing. They dart through ...

Starving Gray Whales Are Swimming Into San Francisco Bay, and Nearly One in Five Dies There Something odd started happening beneath the Golden Gate Bridge in 2018.

Nine Home Runs, One Weird-Shaped Bat, and a Physics Lab That Burst the Bubble Key Takeaways The torpedo bat design aims to move mass toward the sweet spot, but initial tests show similar performance to standard bats. Studies reveal the torpedo bat's sweet spot is slightly closer to the handle, impacting ball speed negatively compared to traditional designs. One tested torpedo bat had a wider sweet spot due to natural wood variability, suggesting some bats may perform better than others.

Why Leg Prosthetics Have Always Lagged Behind Arm Prosthetics, and What Just Changed Every time an above-knee amputee thinks about moving the leg that is no longer there, something happens. Nerve fibres, still intact inside the stump, still connected to the spinal cord and the brain, still faithfully carrying orders, fire. The signal travels down. There is no muscle to receive it. Nothing moves. But the signal is there, complete, legible, waiting for someone who knows how to read it.

A Popular Anti-Aging Drug Combination Strips Myelin from the Brain and Nobody Had Noticed Key Takeaways Oligodendrocytes retract instead of dying under stress, leading to potential implications for myelin regeneration. A study found that dasatinib and quercetin significantly demyelinated mouse brains without killing cells, surprising researchers. The effect was worse in younger mice, suggesting they may depend more on energy pathways affected by D+Q. D+Q-treated cells resembled immature oligodendrocytes found in multiple sclerosis, indicating possible reversibility of demyelination.

Net Zero Is Not Enough. We Need to Pull Carbon from the Air for Centuries A target, it turns out, can be two entirely different things. It can be the finish line (the point at which you stop and declare success). Or it can be a waypoint, a necessary passage on a longer road whose end you cannot yet see clearly. Climate science has spent decades insisting that 1.5 degrees of warming is the number to hold, the ceiling above which things get genuinely bad.

Low Testosterone Is Linked to Higher Risk of Prostate Cancer Becoming More Aggressive The appointment goes something like this. A man has been diagnosed with early-stage prostate cancer. His doctor explains, with genuine reassurance, that the cancer is slow-growing, low-risk, confined. The recommended approach is not surgery, not radiation, but watchful waiting: regular biopsies, PSA blood tests, careful monitoring. The name for this strategy is active surveillance, and for many men it is the right call.

Asteroids Caught Pelting Each Other With Rocky Debris in First Direct Evidence of Binary System Material Transfer Jessica Sunshine knew something was off. The images from NASA's DART spacecraft looked clean enough in the raw data, but once her team at the University of Maryland began correcting for shadows and uneven lighting across the boulder-covered surface of asteroid moon Dimorphos, strange streaks kept appearing. Fan-shaped, faint, converging on a single region just off the visible limb. "At first, we thought something was wrong with the camera, and then we thought it could've been something wrong with our image processing," she says.

New Gravitational Wave Catalog More Than Doubles Known Cosmic Collisions In November 2023, a faint shudder passed through a pair of L-shaped tunnels in Washington state and Louisiana. It had been travelling for a very long time. The signal, once the collaboration's software had picked it apart, told an improbable story: two black holes, each roughly 130 times the mass of the sun, had spiralled into one another and merged. Most colliding black holes that LIGO picks up weigh in at about 30 solar masses.
