U.S. announces 10-year deadline to remove all lead pipes nationwide

By / / Good news links

President Biden has announced $2.6 billion in funding to replace all lead pipes in the United States as part of a new EPA rule that will require lead pipes to be identified and replaced within 10 years using the new funding from the Bipartisan Infrastructure Act. The EPA estimates that nine million homes in the U.S. still have lead pipes. “Studies show … communities of color have been the hardest hit,” Mr. Biden said. “One study showed Black children were at least two times more likely to have elevated levels of lead in their blood than children of other racial groups. We have an obligation to make things right.”

Mpox, previously known as monkeypox, is an infectious disease caused by the monkeypox virus. A global outbreak first emerged in May 2022 which WHO said constituted a public health emergency of international concern – the highest level of alarm under international health law. Africa has seen an unprecedented increase and expansion in mpox cases this year, with transmission mainly centered in the Democratic Republic of the Congo. WHO said early diagnosis is critical as it enables timely treatment and care, as well as control of the virus. A new test from Abbott Molecular now makes that much more possible.

After a smiling Sheinbaum took the oath of office on the floor of Congress, legislators shouted “Presidenta! Presidenta!” using the feminine form of president in Spanish for the first time in over 200 years of Mexico’s history as an independent country. In her inauguration speech, Sheinbaum said that she came to power accompanied by all of the women who have struggled in anonymity to make their way in Mexico, including “those who dreamed of the possibility that one day no matter if we were born as women or men we would achieve our dreams and desires without our sex determining our destiny.”

The entire process currently can take days, weeks, or longer. To speed things up, the researchers focused on the first step: separating two individuals’ DNA from a single sample. At present, this is usually done manually by trained and experienced experts. The new method uses a process called ’differential digestion” using digital microfluidics that helped simplify the overall process and reduce the number of manual steps needed to isolate the assailant’s DNA from 13 to five.

By / / Good news links

Democratic Gov. Andy Beshear banned the use of “conversion therapy” on minors in Kentucky on Wednesday, calling his executive order a necessary step to protect children from a widely discredited practice that tries to change a person’s sexual orientation or gender identity through counseling. The governor used his executive powers after Republicans who control the state legislature repeatedly blocked efforts to enact a state law banning the practice. Beshear said he would no longer wait for others to “do what’s right.”
