How glass frogs -- er, I guess it's one word, glassfrogs -- become transparent has been figured out. "Glassfrogs make themselves transparent while they rest by taking red blood cells from circulation and concealing them in their livers."
"In their imaging set-up, the frogs slept upside down in a petri dish, similar to how they would sleep on a leaf, and the team shined a green laser at the animal. The red blood cells in the frog's body absorbed the green light and emitted ultrasonic waves, which were then picked up by an acoustic sensor to trace their whereabouts, with high spatial resolution and high sensitivity."
"The results were startlingly clear: When the frogs were asleep, they removed nearly 90 percent of their circulating red blood cells and stored them in their liver." The liver has a mirror coating.
Glassfrogs hide red blood cells in their liver to become transparent
Give your dead body to science
Payout: A free cremation
This last idea is sort of morbid, but if you're worried about being a bother when you're dead, you can donate your body to science. This helps with a variety of types of research and education.
Places like BioGift and Science Care will cover the costs of cremation, which can run upwards of US$1,000.

THIS DAY IN HISTORY

December 27
Charles Darwin sets sail from England
British naturalist Charles Darwin sets out from Plymouth, England, aboard the HMS Beagle on a five-year surveying expedition of the southern Atlantic and Pacific oceans. Visiting such diverse places as the Galapagos Islands and New Zealand, Darwin acquired an intimate knowledge of the flora, fauna, and geology of many lands. This information proved invaluable in the development of his theory of evolution, first put forth in his groundbreaking scientific work of 1859, On the Origin of Species by Means of Natural Selection.Darwin’s theory argued that organisms gradually evolve through a process he called “natural selection.” In natural selection, organisms with genetic variations that suit their environment tend to propagate more descendants than organisms of the same species that lack the variation, thus influencing the overall genetic makeup of the species. Most scientists quickly embraced the theory that solved so many puzzles of biological science, but orthodox Christians condemned the work as heresy. Controversy over Darwin’s ideas deepened with the publication of The Descent of Man, and Selection in Relation to Sex (1871), in which he presented evidence of man’s evolution from apes.
By the time of Darwin’s death in 1882, his theory of evolution had become generally accepted. In honor of his scientific work, he was buried in Westminster Abbey beside kings, queens, and other illustrious figures from British history. Subsequent developments in genetics and molecular biology led to modifications in accepted evolutionary theory, but Darwin’s ideas remain central to the field.

Denisovan DNA Shaped Papuans’ Immune System, New Study Shows
Modern humans have admixed with multiple species of archaic hominins. Papuans, in particular, owe up to 5% of their genome to Denisovans, a sister group to Neanderthals whose remains have only been identified in Siberia and Tibet. In Papuans, Denisovan DNA strongly and consistently affects immune cells and immune-related processes of potential evolutionary relevance, according to new research.https://www.sci.news/genetics/denisovan-dna-papuans-immune-system-11464.html
