The topic for the December Journal Club will be the recently published paper – Fisetin is a senotherapeutic that extends health and lifespan. This commonly available supplement and a plant-based polyphenol appears to influence the aging process in mice by clearing senescent cells, one of the suggested reasons we age.

2018 was a huge success! We launched a mission to “touch” the Sun, stuck another nearly flawless #MarsLanding, marked our #NASA60th anniversary of opening our doors for business, welcomed NASA Administrator Jim Bridenstine and began #Apollo50 celebrations! That’s just some of what happened This Year @ NASA — there’s even more at http://www.nasa.gov/2018.


Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal Small, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.

Of course, all the algorithmic rigmarole is also causing real-world problems. Algorithms written by humans — tackling harder and harder problems, but producing code embedded with bugs and biases — are troubling enough. More worrisome, perhaps, are the algorithms that are not written by humans, algorithms written by the machine, as it learns.

Profiles in science.

Donald Knuth, master of algorithms, reflects on 50 years of his opus-in-progress, “The Art of Computer Programming.”
