Researchers say they have found a growth hormone in the colon that helps damage DNA, which aides in the aging process. The finding could lead to new therapeutic approaches to aging-associated disorders like cancer.

Whereas circulating pituitary growth hormones decline with age, non-pituitary growth hormones, or npGH, increase with age. That means the colon tissue growth hormone helps initiate the first stages of tumor development and influence the aging process, Cedars-Sinai Medical Center researchers said in research published in the journal Cell Reports.

At the core of the issue is npGH blocking a certain protein from protecting DNA from damage. The protein, p53, is a tumor suppressor that helps repair DNA, but it can also awaken growth hormones.

The world’s first injectable medication to reduce the risk of acquiring HIV has been approved by the Food and Drug Administration (FDA), the agency announced Monday (December 20).

The injectable drug – called Apretude or its generic name, “cabotegravir extended-release injectable suspension” – provides an alternative to daily pills for HIV prevention, such as Truvada and Descovy. These pills are up to 99 percent effective at preventing the sexual transmission of HIV, but must be taken every day to be that effective, according to the Centers for Disease Control and Prevention (CDC).

By contrast, to start Apretude, people initially receive two shots, spaced one month apart, and then they receive an injection every two months thereafter, according to the FDA statement.

Watch the launch of the James Webb Space Telescope—the most powerful space telescope ever made. This mission is scheduled to lift off at 7:20 a.m. EST (12:20 UTC), Dec. 25, 2021, aboard an Ariane 5 rocket from Europe’s Spaceport in French Guiana.

With revolutionary technology, Webb will observe a part of space and time never seen before, providing a wealth of amazing views into an era when the very first stars and galaxies formed–over 13.5 billion years ago.

It can explore our own solar system’s residents with exquisite new detail and study the atmospheres of distant worlds. From new forming stars to devouring black holes, Webb will reveal all this and more! It’s the world’s largest and most powerful space telescope ever built.

Webb is an international collaboration between NASA, ESA (European Space Agency), and CSA (Canadian Space Agency). Thousands of engineers and hundreds of scientists worked to make Webb a reality, along with over 300 universities, organizations, and companies from 29 U.S. states and 14 countries!

A levitating vehicle might someday explore the moon, asteroids, and other airless planetary surfaces.

Aerospace engineers at MIT

MIT is an acronym for the Massachusetts Institute of Technology. It is a prestigious private research university in Cambridge, Massachusetts that was founded in 1861. It is organized into five Schools: architecture and planning; engineering; humanities, arts, and social sciences; management; and science. MIT’s impact includes many scientific breakthroughs and technological advances.
