The Download: Legitimizing longevity science, and Harvard’s geoengineering U-turn

On a shiny chilly day final December, a crowd of medical doctors and scientists gathered at a analysis institute atop a hill in Novato, California. Their objective is to assist individuals add years to their lifespans, and to stay these further years in good well being. But the assembly’s individuals had one other objective as properly: to be acknowledged as a reputable medical discipline.

For too lengthy, trendy drugs has targeted on treating illness moderately than stopping it, they are saying. They imagine that it’s time to maneuver from reactive healthcare to proactive healthcare. And to take action in a reputable means—by setting “gold standards” and medical pointers for the sector. These scientists and clinicians see themselves spearheading a revolution in drugs.

But proponents acknowledge the challenges forward. Clinicians disagree on how they need to assess and deal with getting old. And with out requirements and pointers, there’s a actual threat that some clinics might find yourself not solely failing to serve their shoppers, however doubtlessly harming them.

Harvard halts its long-planned atmospheric geoengineering experiment

Harvard researchers have ceased a long-running effort to conduct a small geoengineering experiment within the stratosphere, following repeated delays and public criticism.

The fundamental idea behind photo voltaic geoengineering is that the world would possibly be capable of counteract international warming by spraying tiny particles within the environment that would scatter daylight. Proponents of photo voltaic geoengineering analysis argue we must always examine the idea as a result of it could considerably cut back the risks of local weather change.

But critics argue that even finding out the opportunity of photo voltaic geoengineering eases the societal strain to chop greenhouse gasoline emissions. They additionally worry such analysis might create a slippery slope that will increase the percentages that nations or rogue actors will at some point deploy it, regardless of the opportunity of harmful side-effects.
