This tumblr's for all the great men and women of science for whom we owe our current understanding of the natural world; their achievements, their failures, and even their quirks, we celebrate them all.
For Science. For Inquiry. For Humanity.
These are some scientific illustrations of ancient stone tools that I did last summer while working at the Smithsonian Tropical Research Institute.
My work was published in a journal by Elsevier, called the Quaternary International and appeared in Volume 301 “Radiocarbon Chronology of early human settlement in the Isthmus of Panama”.

The drug known as meth has a long and complicated history in medicine and popular culture. A psycho-stimulant with a variety of former medicinal uses in the class of drugs known as amphetamines, meth is a highly addictive and highly destructive illegal and recreational drug. Meth is short for methamphetamine but entered English as meth via the creation of the patented brand name Methedrine, produced by Wellcome Limited beginning in 1939. While there still is a legal version available for prescription for the treatment of both obesity and ADHD, the drug is rarely prescribed.
The word was first used in its shortened form of meth in 1967. The root word meth- has been used in English for a variety of uses since the word methylene was coined by French chemists Jean-Baptiste-André Dumas (1800-1884) and Eugène-Melchior Péligot (1811-1890), who named it from the Ancient Greek word methy (μέθη) meaning strong drink or wine as methylene was first isolated from wood alcohol. In Greek, the word has very little ambiguity: καλῶς ἔχειν μέθης meaning to be good and drunk. Methylene entered French in 1834 and English a year later.

The fruit fly – Drosophila melanogaster – made the jump from nature to laboratory animal in 1901 at Harvard University.
In 1906 Drosophila was adopted by the young evolutionary biologist who would become well known for his work with the flies, Thomas Hunt Morgan, one of the most influential men in experimental biology during the early twentieth century. [Wikipedia - History of Model Organisms]
Morgan, who had been at Columbia since 1904, moved to California in 1928 to develop the new Division of Biology at the California Institute of Technology. In 1933 he received the Nobel Prize in Physiology or Medicine for his work on the role of chromosomes in heredity. [Wikipedia]
Curiosity rover found water molecules in Martian soil
"We tend to think of Mars as this dry place – to find water fairly easy to get out of the soil at the surface was exciting to me," said Laurie Leshin, lead author on the Science paper which confirmed the existence of water in the soil. “If you took about a cubic foot of the dirt and heated it up, you’d get a couple of pints of water out of that – a couple of water bottles’ worth that you would take to the gym.”
These results have implications for future Mars explorers. “We now know there should be abundant, easily accessible water on Mars,” said Leshin. “When we send people, they could scoop up the soil anywhere on the surface, heat it just a bit, and obtain water.”
