Meta and its subcontractor are disputing the reasons behind the sudden layoff of over 1,000 Kenya-based content moderators. The workers were reportedly dismissed after reviewing highly explicit footage from Meta's smart glasses, including videos of users having sex. The two companies currently disagree on the exact cause of these mass redundancies.

The Church Rock uranium mill spill released 1.36 tons of uranium and radioactive contaminants into the Puerco River, severely contaminating the water supply used by the Navajo Nation. The disaster received significantly less media coverage and federal assistance than Three Mile Island, a disparity readers attribute to its rural location and the marginalization of the affected Native American community.

An open-source, research-validated stethoscope has been developed that costs between $2.50 and $5 to produce. The GliaX/Stethoscope project provides the complete manufacturing plans entirely for free, aiming to drastically improve global access to essential diagnostic equipment.

Researchers have identified a novel synaptic plasticity mechanism that explains how the brain rewires itself to learn across extended timescales following an experience. This discovery expands beyond the traditional concept of neurons simply wiring together when firing simultaneously, offering deeper insights into complex long-term learning.

The popular period tracking app Flo has been found sharing sensitive user data with Meta, exposing the vulnerabilities in digital health monitoring. This revelation highlights the risks of vague data collection policies and raises critical concerns about the privacy of self-monitoring biological markers.

The U.S. Food and Drug Administration has approved Otarmeni, the first-ever dual adeno-associated virus (AAV) vector-based gene therapy, to treat genetic hearing loss. This landmark decision marks a significant breakthrough in utilizing advanced viral vector technology to address hereditary medical conditions.

A recent Freakonomics report examines the scientific and systemic barriers, including an overreliance on outdated biological hypotheses, that have historically slowed progress in Alzheimer's disease research. The segment highlights that overcoming these challenges will require innovative biotechnological approaches, earlier clinical interventions, and a fundamental shift in how the disease is studied and funded.

Marking four decades since the Chernobyl nuclear disaster, researchers are evaluating the long-term effects of radiation on the surrounding wildlife.
