The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.
Study investigates source of Amazon’s “Dark Earth” – Created intentionally? It is less acidic than surrounding soils…probably from the addition of ash.
New York City Greenery Absorbing All Traffic Emissions on Many Summer Days – There is a lot more greenery that previously thought…looking beyond parks to modest backyards, shrubbery growing in vacant lots, and trees dotting city sidewalks. That’s good for the summer when everything is green and growing….but it also implies that winter air quality is problematic.
‘Stomp’ Performers Hang Up their Garbage Lids – After 3 decades off-Broadway. Watch the video!
Riddle solved: why is Roman concrete so durable? – It wasn’t just volcanic ash that made Roman concrete better…lime clasts play a self-healing role!
Why is every parking lot covered with solar panels? – Evidently Michigan State has done it…hopefully other universities and big box stores do similar projects.
How the war in Ukraine is killing marine mammals – The dolphins that were washing up on the shore of the Black Sea prior to the war were few and usually had markings suggesting entanglement in fishing gear. The theory about the increased number appearing now, without marks, is that the dolphins are experiencing acoustic trauma from the increased use of sonar by Russian submarines.
Climate impact labels on sample food menu had strong effect on food selection – A study done by Johns Hopkins. The result indicate that this kind of labelling could promote more sustainable choices….and have positive health benefits as well!
Aerial Photos Capture the Abstract Beauty of Salt Ponds – From a new book….with images and background about these man-made landscapes.
Great Salt Lake will disappear in 5 years without a massive ‘emergency rescue’ – My husband and I visited the lake back in 2008. The pictures in the article are so different that I needed the captions to recognize the place. The lake was already shrinking in 2008 but the shrinking has increased with long term drought and increased population diverting more water that would otherwise flow into the lake. Aside from the ecological collapse if the lake goes dry, the dust from the dry lakebed is kicked up by winds and can damage lungs/exacerbate other respiratory illness. This does not bode well for public health in Salt Lake City.
Painted skulls from Peru’s Chincha Valley analyzed – The red paint on the skulls was not all the same on all the skulls: some have iron-based ochres and others have mercury-based cinnabar….the red paint on one of the skulls was a combination of the two!
