trees on New York City Street Map
21,611 Ginkgo trees are highlighted on the New York City Street Tree Map.
The New York City Street Tree Map is the world’s most accurate and detailed map of a city’s street trees. More about this project here.
New York City Parks about the Ginkgo trees in a tweet on Twitter of August 28:

Results of the research, supported by the National Science Foundation (NSF), are published in this week’s issue of the journal Proceedings of the National Academy of Sciences (PNAS).
stems and leaves are similar to the Ginkgo tree, but the seeds, and especially
the structures they are born in, are unlike any other known plant, living
or extinct," says scientist Patrick Herendeen of the Chicago Botanic Garden,
co-author of the PNAS paper.
The seed-bearing structures are more comparable to those of certain extinct Peltaspermales and Umkomasiales.
Ginkgo may be the last survivor of a once highly diverse group of extinct plants, several of which show various degrees of ovule enclosure.

wood provides insights into Ginkgo wood evolution
Recently, Chinese and French scientists led by Wang Yongdong, professor at Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences, researched new fossil wood of Ginkgo biloba. The fossil wood (Ginkgoxylon liaoningense) was collected from the Tiaojishan Formation in western Liaoning, northeastern China. It probably dates from the Middle to Late Jurassic.
According to the researchers this discovery represents the oldest well-dated occurence of Ginkgo wood.
Its anatomy departs slightly from that of modern Ginkgo, it displays all its characteristic features. It differs only in having a more mixed type of radial pitting, which also occurs, albeit locally, in modern Ginkgo wood. The xylem structures of Ginkgoxylon liaoningense illustrates the basal state of Ginkgo wood anatomy and will contribute to the understanding of Ginkgo evolution.

Multiple seeds at visually different developmental stages were collected from five separate large Ginkgo trees at one of the Ginkgo refuge populations located on Tianmu Mountain, Zhejiang Province, China.

initiative is called "Green Legacy Hiroshima" in which UNITAR is working
with Hiroshima institutions and United Nations Office at Geneva (UNOG)
Director-General to coordinate and arrange the planting of a Ginkgo Atomic
bombed tree sapling from Hiroshima, in the Ariana Park of the Palais des
Nations, the UN headquarters in Europe. The Ginkgo tree will symbolise
hope, resilience and peace, as well as generosity and beauty. The seeds
and saplings of A-bombed survivor trees are being sent by the Green Legacy
Hiroshima team to symbolic sites around the world, with activities unfolding
in some 25 countries.
The Secretary-General Mr. Ban Ki-moon will personally plant the tree at the Palais des Nations later this year.

Asteroid 85197 (1991 TG5) is named Ginkgo after the Ginkgo biloba tree. It is a main-belt asteroid discovered on October 5, 1991 by F. Borngen and L. D. Schmadel of the Karl Schwarzschild Observatory at Tautenburg, Germany. Read more on Wikipedia and on this site by NASA Jet Propulsion Laboratory, California.
Ron Baalke pointed me to this asteroid on my Twitter. Ginkgo made its closest approach to Earth on December 24, 2014:
