Margalit Fox's superb New York Times obituary  brought home to me just how great this artist,

Tomato seeds that went to space aboard Challenger and Columbia are on my desk

Bold

Above and below, the packet of seeds I obtained through somewhat dishonest means back in the early 90s.

Long story short: NASA offered packets of space-exposed seeds to teachers for use in their classrooms, to conduct experiments on viability and growth.

Since I was an associate professor of anesthesiology at the University of Virginia School of Medicine at the time, I figured I fell under the heading "teacher," so I wrote and requested seeds.

Sure enough, back came the metallic sealed packet pictured above and below.

Faint

The text on one side of the packet:

These seeds were flown in space aboard the LDEF [Long Duration Exposure Facility] which was launched April 6, 1984, on Space Shuttle Challenger and returned to Earth January 20, 1990, on Space Shuttle Columbia.

I've never opened the packet because it seemed — and still seems — much more wondrous to think about the dormant, space-exposed seeds in situ.

I wonder if they would grow if planted....

The packet says: 

Sealed at scientifically controlled low moisture content to insure peak vigor in the seed until you are ready to plant.

...............................................

Note added Februrary 9, 2020 at 2:21 p.m.:

Reader antares commented, "Joe, I suggest you leave the packet unopened as a memoriam. Those seeds flew in the two shuttles that were lost."

Done.

3,000-year-old mummy "speaks"

Screen Shot 2020-02-08 at 10.45.44 AM

[caption for photo above: The mummy of Nesyamun, a priest who lived in Thebes about 3,000 years ago, ready for CT scanning]

The original paper was published in Nature on January 23, 2020.

Below, the abstract.

Synthesis of a vocal sound from the 3,000-year-old mummy Nesyamun, "True of Voice"

The sound of a 3,000 year old mummified individual has been accurately reproduced as a vowel-like sound based on measurements of the precise dimensions of his extant vocal tract following Computed Tomography (CT) scanning, enabling the creation of a 3D printed vocal tract. By using the Vocal Tract Organ, which provides a user-controllable artificial larynx sound source, a vowel sound is synthesized which compares favorably with vowels of modern individuals.

An excellent New York Times story has an audio link so you can hear the mummy speak.
