• Vaccines have been effective in reducing the prevalence of an array of diseases.
• In spite of some major successes, deep challenges still exist in guaranteeing equitable distribution of vaccines around the world, including a North-South divide.
• A rise in vaccine hesitancy and a U.S. administration that is withdrawing from global health programs cast doubt on the future of vaccination.

More children are taking the hormone in the form of nightly gummies or drops. The long-term effects are unclear.

In the Amazon, gold mining is a thriving business, pushing deep into the rainforest and indigenous lands. Small-scale operations set up primarily illicitly and operated in the shadows use mercury, a substance with neurotoxic properties, for gold extraction. Now, a team of researchers examined if trees native to the Peruvian Amazon could be used as biomonitors for gold mining activities. By examining mercury concentrations in tree rings, they concluded that some species could bear witness to illegal mining activities.

By understanding how gratitude naturally develops in children, we can encourage rather than enforce thankfulness.

An analysis by the U.S. Defense Department’s intelligence agency concluded five years ago that the virus that caused COVID-19 could have been engineered in a Chinese laboratory and later escaped to spawn the pandemic that eventually killed millions of people, recently released documents obtained by US Right to Know show.

The never-before-published analysis by the Defense Intelligence Agency (DIA) points out that the lab in question – the Wuhan Institute of Virology – was highly capable of genetic manipulation, and includes an assessment that the genome of the coronavirus strain that caused COVID-19 is “consistent with the hypothesis” that it was “a lab-engineered virus” that “escaped from containment.”

The analysis by scientists in the DIA, which is charged with collecting and analyzing medical and health intelligence as part of its operations, also concluded that the virus that became known as SARS-CoV-2 could have come from “a bank” of bat coronaviruses in the Wuhan lab that was under the research of senior virologist, Dr. Shi Zhengli.
