Catch Up Drive Delivers 100 Million Vaccinations
A catch up initiative led by the World Health Organization and UNICEF delivered more than 100 million vaccine doses to 18.3 million children across 36 countries between 2023 and 2025. Of those children, 12.3 million had never received a single vaccine. The effort restored immunization coverage that was lost when health services closed during the pandemic. Read more here.
Hepatitis B in Young Children Falls to 0.6 Percent
Hepatitis B prevalence among children under five has fallen to 0.6 percent, with 85 countries now meeting the 0.1 percent elimination target. Birth dose and routine infant vaccination drove the change, and new infections are down 32 percent since 2015. Most chronic hepatitis B infections begin in early childhood, so lowering infection now prevents liver disease decades later. Read more here.
Brain Implant Restored Speech for Nearly Two Years
A man with ALS used a brain implant to produce more than 183,000 sentences over nearly two years at home, at 56 words per minute with 99 percent word accuracy. The device reads signals from the speech area of the motor cortex and converts them into words drawn from a 125,000 word vocabulary. It is the first report of a speech neuroprosthesis used independently outside a laboratory over a sustained period. Read more here.
Veteran Homelessness Down 56 Percent Since 2009
The January 2025 point in time count found 32,495 veterans experiencing homelessness on a single night, down from 32,882 two years earlier. Housing vouchers and case management account for most of the long run decline, which now stands at 56 percent since 2009. Veterans were once sharply overrepresented among people without housing, and that gap has narrowed steadily. Read more here.
Global Electric Car Sales Top 20 Million
Global electric car sales exceeded 20 million in 2025, about one quarter of all new cars sold worldwide. European sales rose more than 30 percent, electric cars reached nearly 55 percent of sales in China, and Southeast Asian sales more than doubled. The International Energy Agency expects 23 million sales in 2026. Read morer here.
Northeastern Bulrush Leaves the Endangered List
The U.S. Fish and Wildlife Service removed the northeastern bulrush from the endangered species list after populations grew from 13 in six states in 1991 to 148 in eight states. Surveys, landowner habitat agreements, and state wetland management expanded the plant's known range over three decades. Delisting on the basis of recovery remains uncommon. Read more here.
