Alejandro De Los Angeles is a visiting researcher at Yale University. He has done research at several leading institutions, including Stanford, Yale, Columbia, and the Genome Institute of Singapore. A Connecticut native, he has published over 25 papers on stem cells and human-animal interspecies chimeras. Alejandro’s research has focused on identifying stem cells capable of forming interspecies chimeras. Recently, Alejandro discovered a new type of monkey pluripotent stem cell that might possess the capability of forming interspecies chimeras. He also showed that the same method works in human stem cells. De Los Angeles’s work has appeared in major scientific journals, including the top journal Nature. In addition to his scientific work in the laboratory, he also collaborates with bioethicists and recently co-edited a book on chimera research and ethics titled, “Chimera Research,” published by Springer Nature.

This video explains the science behind the longevity of a 105-year-old sprinter.

No human has run a distance of 100 meters faster than Usain Bolt’s lightning streak in 2009. He set this record at age 22. But what will Bolt’s time be when he’s 105?

At the Louisiana Senior Games in November 2021, 105-year-old Julia Hawkins of Baton Rouge became the oldest woman to run 100 meters in an official competition, qualifying her for this year's National Senior Games. Perhaps not surprisingly, she was the only competitor in the race for people 105 and older. In this Leaps.org video, I interview Hawkins about her lifestyle habits over the decades. Then I ask Steven Austad, a pioneer in studying the mechanisms of aging, for his scientific insights into how those aspiring to become super-agers might follow in Hawkins' remarkable footsteps.

Ring vaccination strategy can rein in monkeypox virus, scientists say

Monkeypox produces more telltale signs than COVID-19. Scientists think that a “ring” vaccination strategy can be used when these signs appear to help with squelching the current outbreak of this disease.

A new virus has emerged and stoked fears of another pandemic: monkeypox. Since May 2022, it has been detected in 29 U.S. states, the District of Columbia, and Puerto Rico among international travelers and their close contacts. On a worldwide scale, as of June 30, there have been 5,323 cases in 52 countries.

The good news: An existing vaccine can go a long way toward preventing a catastrophic outbreak. Because monkeypox is a close relative of smallpox, the same vaccine can be used—and it is about 85 percent effective against the virus, according to the World Health Organization (WHO).
