Humanity has evolved in the face of much hardship and turmoil, and invented technologies to aid us, but could an end to hardships be our undoing and cause us to devolve?

The association between this mass concentration and the idea that atoms are empty stems from a flawed view that mass is the property of matter that fills a space. However, this concept does not hold up to close inspection, not even in our human-scale world. When we pile objects on top of each other, what keeps them separated is not their masses but the electric repulsion between the outmost electrons at their touching molecules. (The electrons cannot collapse under pressure due to the Heisenberg uncertainty and Pauli exclusion principles.) Therefore, the electron’s electric charge ultimately fills the space.

Anyone taking Chemistry 101 is likely to be faced with diagrams of electrons orbiting in shells.

In atoms and molecules, electrons are everywhere! Look how the yellow cloud permeates the entire molecular volume in Figure 1. Thus, when we see that atoms and molecules are packed with electrons, the only reasonable conclusion is that they are filled with matter, not the opposite.

The origin of the hominines is among the most hotly debated topics in paleoanthropology. The traditional view, ever since Darwin, holds that hominines and hominins originate in Africa, where the earliest hominins are found and where all extant non-human hominines live. More recently a European origin has been proposed, based on the phylogenetic analysis of late Miocene apes from Europe and Central Anatolia^1,2,3 The fossils described here attest to a lengthy history of hominines in Europe, with multiple taxa in the eastern Mediterranean known for at least 2.3 Ma^4,5,6,7 Our phylogenetic analysis, based on the new specimens described here and a large sample of other fossil and extant hominoids (Supplementary Note 1, Tables 1, 2), supports previous research confirming the hominine status of the eastern Mediterranean apes^{2,3,8,9,10,11,12,13,14,15,16,17,18,19,20} Our most parsimonious phylogenetic results suggest that hominines in the eastern Mediterranean evolved from dryopithecins in central and western Europe, though there are alternative interpretations^21,22,23,24. Either way, the oldest known hominines are European. They may have dispersed into Europe from ancestors in Africa, only to become extinct²² However, the more likely and more parsimonious interpretation is that hominines evolved over a lengthy period in Europe and dispersed into Africa before 7 Ma.

For some time, the only known late Miocene ape from Anatolia was Ankarapithecus, which is alternatively described as a stem hominid or a pongine^25,26,27, but not a hominine. It is easily distinguished from Our anopithecus and Graecopithecus from Greece and Bulgaria^25,26,27 In 2007, a new species of Our anopithecus was described from Çorakyerler in central Anatolia²⁸. Since then, thousands of vertebrate fossils have been recovered at Çorakyerler, including a well-preserved ape partial cranium²⁹ (Fig. 1) The O. turkae holotype, a fragmented palate, was originally distinguished from O. macedoniensis in its shorter premaxilla, narrower palate, morphologically similar (homomorphic) upper premolars (as opposed to P3 being more triangular than P4), smaller male canines and possibly larger size²⁸. However, recovery of the new cranium and our reanalysis of the published material requires a reassessment of this conclusion and justifies the naming of a new genus of Miocene hominine.

A team of physicists and geologists at CEA DAM-DIF and Universit´e Paris-Saclay, working with a colleague from ESRF, BP220, F-38043 Grenoble Cedex and another from the European Synchrotron Radiation Facility, has succeeded in synthesizing a single-crystalline iron in a form that iron has in the Earth’s core.

In their paper published in the journal Physical Review Letters, the group describes how they used an experimental approach to synthesize pure single-crystalline ε-iron and possible uses for the material.

In trying to understand Earth’s internal composition, scientists have had to rely mostly on seismological data. Such studies have led scientists to believe that the core is solid and that it is surrounded by liquid. But questions have remained. For example, back in the 1980s, studies revealed that seismic waves travel faster through the Earth when traveling pole to pole versed equator to equator, and no one could explain why.

When supermassive black holes barrel toward collision, they can reach speeds of up to 1/10th the speed of light, new research suggests.

New bionic hand with better move of fingers.

Successful testing of the bionic hand has already been conducted on a patient who lost his arm above the elbow.

In a world first, surgeons and engineers have developed a new bionic hand that allows users with arm amputations to effortlessly control each finger as though it was their own body.

How looks life with na implant in brain.

Brain-computer interface technology is a fast-growing field but how does it feel to live with an implant inside of you?

In 2014, Ian Burkhart looked down at his hand and imagined closing it. To his astonishment, his hand did just that.

The “chemical cocktail” helped reverse aging in mice, but some experts are skeptical about whether it will work in humans.

The viral ALS Ice Bucket Challenge a few years ago raised major funding that resulted in the discovery of new genes connected to the disease. One of those genes is NEK1, in which mutations have been linked to as much as 2% of all ALS cases, making it one of the top-known causes of the disease.

But it wasn’t known how the mutated gene disrupts the function of the motor neuron and causes it to degenerate and die.

Northwestern Medicine scientists have discovered for the first time how this mutated gene leads to ALS (amyotrophic lateral sclerosis).
