Switch Off the Aging Genes
By manipulating eight strands of D.N.A. that control the production of a crucial hormone linked to old age, scientists believe they could slow down the ageing process and ward off age related conditions.
What's the Most Recent Development?
"For 50 years [scientists] have observed the most abundant circulating steroid in the body, DHEAS, with no clue as to its role. Now its genes have shown us its importance in many parts of the ageing process," said professor Tim Spector of King's College in London. Spector has coauthored a report studying the link between the production of DHEAS and the aging process in over 14,000 people from Europe and the U.S. The steroid is also linked to medical conditions associated with aging, such as type 2 diabetes and lymphoma. Spector's team will spend the rest of the year looking closer at the eight genes that regulated DHEAS production.
What's the Big Idea?
Is modern science approaching a watershed moment with regards to aging? Average life expectancy has nearly doubled in the last century thanks to advances in modern medicine and democratized health care systems, but will we soon be able to directly manipulate our genes to achieve near-immortality? If the process of aging is caused by specific chemical reactions in our body, is it worth neutralizing those reactions. Beyond scientific possibilities, other serious questions abound: Do we have the resources to support an immortal population? What would motivate an immortal to act today given an infinite number of tomorrows?
Former president of the ACLU Nadine Strossen discusses whether our society should always defend free speech rights, even for groups who would oppose such rights.
- Former ACLU president Nadine Strossen understands that protecting free speech rights isn't always a straightforward proposition.
- In this video, Strossen describes the reasoning behind why the ACLU defended the free speech rights of neo-Nazis in Skokie, Illinois, 1977.
- The opinions expressed in this video do not necessarily reflect the views of the Charles Koch Foundation, which encourages the expression of diverse viewpoints within a culture of civil discourse and mutual respect.
Going back to the moon will give us fresh insights about the creation of our solar system.
- July 2019 marks the 50th anniversary of the moon landing — Apollo 11.
- Today, we have a strong scientific case for returning to the moon: the original rock samples that we took from the moon revolutionized our view of how Earth and the solar system formed. We could now glean even more insights with fresh, nonchemically-altered samples.
- NASA plans to send humans to a crater in the South Pole of the moon because it's safer there, and would allow for better communications with people back on Earth.
Pugs and bulldogs are incredibly trendy, but experts have massive animal welfare concerns about these genetically manipulated breeds.
- Pugs, Frenchies, boxers, shih-tzus and other flat-faced dog breeds have been trending for at least the last decade.
- Higher visibility (usually in a celebrity's handbag), an increase in city living (smaller dogs for smaller homes), and possibly even the fine acting of Frank the Pug in 1997's Men in Black may be the cause.
- These small, specialty pure breeds are seen as the pinnacle of cuteness – they have friendly personalities, endearing odd looks, and are perfect for Stranger Things video montages.
Jokesters and serious Area 51 raiders would be met with military force.
- Facebook joke event to "raid Area 51" has already gained 1,000,000 "going" attendees.
- The U.S. Air Force has issued an official warning to potential "raiders."
- If anyone actually tries to storm an American military base, the use of deadly force is authorized.
