MIT scientists reverse opioid overdoses with ‘Narcan sensor’ implanted under skin

| By | -, Good News Links

In 2023, more than 100,000 Americans died from opioid overdoses. The most effective way to save someone who has overdosed is to administer a drug called naloxone, but help can’t always reach the person in time. Researchers at MIT and Brigham and Women’s Hospital have developed a new device to address this problem. The device, about the size of a stick of gum, can be implanted under the skin. When it determines that an overdose has occurred, it rapidly pumps out a dose of naloxone.

Seastar

Lab-grown starfish released into wild for the first time ever, saving species from extinction

| By | -, Good News Links

Due to sea star wasting disease, lower oxygen levels in seawater, and rising temperatures, starfish populations are at risk around the globe. Across the last decade, the sunflower star population plummeted by over 90%. Fortunately, in 2019, marine biologist Jason Hodin stepped up to save the sea stars from extinction. At the University of Washington’s Friday Harbor Labs, Hodin has carefully grown and raised several generations of sunflower starfish in a controlled environment, breeding them from a select sample of starfish he rescued from the harbor five years prior.

Crime in England and Wales has plummeted 80% in 30 years

| By | -, Good News Links

As of 2024, violence, burglary, and car crime have been declining for 30 years and by close to 90%, according to the Crime Survey for England and Wales (CSEW). The drop in violence includes domestic violence and other violence against women. Anti-social behavior has similarly declined. While increased fraud and computer misuse now make up half of crime, this mainly reflects how far the rates of other crimes have fallen.

Bangladesh achieves major victory in olive ridley turtles conservation

| By | -, Good News Links

This year, Bangladesh has seen its highest number of olive ridley turtle eggs, thanks to extensive conservation actions, including building awareness among local people and the vigilance of local conservation groups to ensure favorable conditions for the species. The number of eggs has increased by almost 53% compared with the previous year, from 8,096 to 12,425. Those tallies represent a significant jump from the 4,713 eggs recorded in 2020-2021 and 5,763 in 2022-23. The olive ridley is listed as an endangered turtle on the IUCN Red List.

According to a recent study from Our World In Data, in the early-to-mid 20th century, the average annual death toll from disasters was very high, often climbing to over a million. In recent decades, such deaths are typically fewer than 20,000 people, even as natural disasters become more frequent and more extreme.

Scientists successfully 3D-print human skin tissue into open wounds

| By | -, Good News Links

Scientists at Pennsylvania State University have successfully 3D-printed living human skin tissue directly into the open wounds of rats for the first time in history. This bioengineering milestone could pave the way for major developments in reconstructive surgery — or even human hair treatments. Current methods of skin and hair reconstruction — like skin grafts — often result in scars, meaning this discovery could lead to a more seamless treatment for humans.

Denver will now pay residents who commute on bikes

| By | -, Good News Links

The city’s new Bicycling Rewards Program aims to encourage community members to ride a bike instead of driving. The program comes as a response to the city’s lagging climate goals. According to Denver Streets Partnership, transportation was responsible for 30% of the city’s greenhouse gas emissions in 2018, and this incentive is part of a larger research project to see what motivates locals to ditch their cars.

Colorado to be first state in the U.S. to expand automatic voter registration to tribes

| By | -, Good News Links

Tribal communities in Colorado share some of the same registration and voting barriers as other rural communities across the U.S., like geographic isolation and unreliable mail delivery. But according to the Native American Rights Fund, tribal communities also commonly experience obstacles like language barriers, a lack of voter registration opportunities, and state laws in some parts of the country that block polling places on tribal lands.
