Technology For The Blind!

This slender-snouted crocodile skull in Carnegie Museum of Natural History’s Alcohol House was used to determine that each African region had a unique crocodile species. You can see this skull and its story on display at the new We Are Nature. Look for the Alcohol House media interactive in the gallery!

it is absolutely my kind of thing. so much work, such intricate pieces! I would’ve loved to be on the team that put this together.

Creepy or adorable? Researchers at Harvard University have demonstrated the first autonomous, untethered, entirely soft robot: the octobot.

Instead of being controlled by electronics, the robot’s logic board is powered by chemical reactions and fluid passing along tiny channels. Scientist have struggled to create completely soft robots because rigid components like circuit boards, power sources and electronic controls are difficult to replace.

Today's Men Carry Traces of Ancient Wars in Their Genes

Modern men’s genes suggest that something peculiar happened 5,000 to 7,000 years ago: Most of the male population across Asia, Europe and Africa seems to have died off, leaving behind just one man for every 17 women.

This so-called population “bottleneck” was first proposed in 2015, and since then, researchers have been trying to figure out what could’ve caused it. One hypothesis held that the drop-off in the male population occurred due to ecological or climatic factors that mainly affected male offspring, while another idea suggested that the die-off happened because some males had more power in society, and thus produced more children.

Now, a new paper, published May 25 in the journal Nature Communications, offers yet another explanation: People living in patrilineal clans (consisting of males from the same descent) might have fought with each other, wiping out entire male lineages at a time. Read more.

no seriously at what point do we stop saying dinosaurs and start saying prehistoric birds?? is it a matter of time?? a matter of species??? SCIENCE SIDE OF TUMBLR PLEASE HELP

Most Intact Australopithecus Unveiled

After 20 years of painstaking excavation, cleaning, and reassembling, the virtually intact skeleton of the Australopithecus hominid known as Little Foot has been revealed to the world.

Bones from the 3.67-million-year-old human ancestor were first identified in the 1990s within the Sterkfontein caves northwest of Johannesburg, in South Africa. Little Foot represents the most complete Australopithecus ever discovered.

I said I was sorry.

I may be awkward sometimes But

at least i did not say “neat”

X-ray binary (black hole devouring a star)

X-ray binaries are a class of binary stars that are luminous in X-rays. The X-rays are produced by matter falling from one component, called the donor (usually a relatively normal star), to the other component, called the accretor, which is very compact: a neutron star or black hole. The infalling matter releases gravitational potential energy, up to several tenths of its rest mass, as X-rays. (Hydrogen fusion releases only about 0.7 percent of rest mass.) The lifetime and the mass-transfer rate in an X-ray binary depends on the evolutionary status of the donor star, the mass ratio between the stellar components, and their orbital separation.

An estimated 1041 positrons escape per second from a typical low-mass X-ray binary.
