Did humans evolve from monkeys or from fish? In this enlightening talk, ichthyologist and TED Fellow Prosanta Chakrabarty dispels some hardwired myths about evolution, encouraging us to remember that we’re a small part of a complex, four-billion-year process — and not the end of the line. “We’re not the goal of evolution,” Chakrabarty says. “Think of us all as young leaves on this ancient and gigantic tree of life — connected by invisible branches not just to each other, but to our extinct relatives and our evolutionary ancestors.”

This talk was presented at an official TED conference, and was featured by our editors on the home page.

Aerogels are the world’s lightest (least dense) solids. They are also excellent thermal insulators and have been used in numerous Mars missions and the Stardust comet particle-return mission. The focus of this video is silica aerogels, though graphene aerogels are now technically the lightest. At one point Dr. Steven Jones literally held the Guinness World Record for making the lightest aerogel and therefore lightest solid. If you’re interested in learning more about aerogels, let me know in the comments as there is a potential trilogy in the works… Huge thanks to Dr. Stephen Steiner and the crew at Aerogel Technologies. To find out more or buy your own aerogel sample, check out: http://www.aerogeltechnologies.com/ Thanks to Dr. Steven Jones and Dr. Mihail Petkov at NASA’s Jet Propulsion Laboratory And thanks to FLIR for loaning us the awesome high definition thermal camera.

Egypt archaeologists find 20 ancient coffins near Luxor 16 October 2019

Image copyright Egypt Antiquities Ministry Image caption More details about the discovery will be released at a news conference on Saturday

Archaeologists have found more than 20 ancient wooden coffins near the Egyptian city of Luxor, the country’s antiquities ministry says.

The coffins, whose brightly-coloured decorations are still visible, were uncovered at the Theban necropolis of Asasif, on the River Nile’s west bank.

They were in two layers, with the ones on top across those below.

The ministry described the discovery as “one of the largest and most important” in recent years.

More details will be released at a news conference on Saturday.

Most of the tombs at Asasif, which is close to the Valley of the Kings, are from the Late Period (664-332BC) of ancient Egypt.

However, there are also tombs from the earlier 18th Dynasty (1550-1292BC), which was the first of the New Kingdom and included the famous pharaohs Ahmose, Hatshepsut, Thutmose III, Amenhotep III, Akhenaton and Tutankhamun.

Last week, the antiquities ministry announced that archaeologists had discovered an ancient “industrial area” in Luxor’s West Valley.

The area included “houses for storage and the cleaning of funerary furniture, with many potteries dated to the 18th Dynasty”, it said.

A 21 Foot-Long Painting of The Last Supper by 16th Century Nun and Artist Plautilla Nelli Has Just Been Painstakingly Restored

October 24, 2019  Laura Staugaitis

In the 1500’s self-taught artist and nun Plautilla Nelli created a life-size mural of Jesus and the twelve apostles at the Last Supper. Spanning 21 feet feet, the vibrantly colored painting includes carefully rendered details including wine chalices, salt cellars, wood panelling, and a rhythmically creased tablecloth. In addition to the inanimate objects depicted, Nelli demonstrated impressive facility with human anatomy in her renderings of the religious figures—at the time, women were barred from studying the field of anatomy.

Nelli’s masterpiece stayed for two centuries at her convent, Santa Caterina, and then changed locations a few times before being unstretched, rolled, and put in storage about a hundred years ago. After an initial restoration and then additional damage due to flooding in the 1960’s, The Last Supper has been undergoing restoration for the past four years. Brought back to life by an all-female team of curators, restorers, and scientists at Advancing Women Artists, it is now on permanent display at the Santa Maria Novella Museum in Florence, Italy.
