IRS free tax filing program launches in 12 pilot states

While the pilot focuses on “simple tax situations,” the U.S. Treasury estimates the pilot could cover about one-third of tax situations for 19 million taxpayers. Within five years, the program could save the average filer $160 per year, or a collective $11 billion annually including tax prep fees and time, according to a report from the Economic Security Project.

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

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.

Health Canada to completely ban use of strychnine poison

Strychnine has been used for decades to control animal pests, especially predators such as coyotes and wolves. Although it is highly effective, many consider it cruel. Strychnine kills by causing muscle cramps that eventually strangle the animal. A veterinary professor has called it “one of the worst ways to die.” The agency has declared a six-month phaseout period. That means all uses of strychnine will be illegal on September 7, 2024.

New satellite pinpoints global methane pollution in real-time

MethaneSAT, developed by the Environmental Defense Fund in partnership with the New Zealand Space Agency, is the size of a washing machine and cost $88 million to build and launch. While part of its mission is to spot polluters, the other side of the coin is that it can verify that others are indeed managing those emissions in a responsible fashion. Stemming methane leaks is the fastest single way to curb the escalation of average global temperatures, according to The Guardian.

President Biden brokers $1 billion deal with Oregon, Washington, 4 Columbia River tribes to revive Northwest salmon population

The plan brokered by the Biden administration pauses long-running litigation over federal dam operations and represents the most significant step yet toward eventually taking the four Snake River dams down. The plan will strengthen tribal clean energy projects and provide other benefits for tribes and other communities that depend on the Columbia Basin for agriculture, energy, recreation and transportation, the White House said.

96% of all new power capacity in the U.S. in 2024 will be carbon-free

In 2024, the U.S. power industry is choosing clean energy for almost all its new capacity additions. The latest federal forecast for power plant additions from the U.S. Energy Information Administration shows solar sweeping with 58% of all new utility-scale generating capacity this year. In an upset, battery storage will provide the second-most new capacity, with 23%. Wind delivers a modest 13%, while the long-delayed final nuclear reactor at Vogtle in Georgia will add 2% of new capacity.
