A hint of new physics in polarized radiation from the early universe — ScienceDaily

Using Planck data from the cosmic microwave background radiation, an international team of researchers has observed a hint of new physics. The team developed a new method to measure the polarization angle of the ancient light by calibrating it with dust emission from our own Milky Way.

While the signal is not detected with enough precision to draw definite conclusions, it may suggest that dark matter or dark energy causes a violation of the so-called “parity symmetry.”

The laws of physics governing the Universe are thought not to change when flipped around in a mirror. For example, electromagnetism works the same regardless of whether you are in the original system, or in a mirrored system in which all spatial coordinates have been flipped.

If this symmetry, called “parity,” is violated, it may hold the key to understanding the elusive nature of dark matter and dark energy, which occupy 25 and

Signs of Recent Volcanic Eruption on Mars Hint at Habitats for Life

Mars was once home to seas and oceans, and perhaps even life. But our neighboring world has long since dried up and its atmosphere has been blown away, while most activity beneath its surface has long ceased. It’s a dead planet.

Or is it?

Previous research has hinted at volcanic eruptions on Mars 2.5 million years ago. But a new paper suggests an eruption occurred as recently as 53,000 years ago in a region called Cerberus Fossae, which would be the youngest known volcanic eruption on Mars. That drives home the prospect that beneath its rusty surface pocked with gigantic volcanoes that have gone silent, some volcanism still erupts to the surface at rare intervals.

“If this deposit is of volcanic origin then the Cerberus Fossae region may not be extinct and Mars may still be volcanically active today,” scientists at the University of Arizona and Smithsonian Institution, write in

A female hunter’s remains hint at more fluid gender roles in the early Americas

Women in early hunter-gatherer groups regularly hunted big game alongside their male peers, indicates a study published on November 4 in the journal Science Advances. Researchers excavated a 9,000-year-old partial skeleton in the Andes buried with hunting tools and determined that the remains belonged to a young woman. The team also pored over previous reports of human remains from this time period, and found numerous other examples of women in North and South America buried with tools used in big-game hunting.

A number of researchers have speculated that some ancient societies might have had a more equal division of labor.

“This was really surprising to us…given our understanding of the world, which was that in hunter-gatherer societies males hunt and females gather or process subsistence resources,” says Randall Haas, an archaeologist at the University of California, Davis. In more recent and contemporary hunter-gatherer societies,

Godfall System Requirements Hint At Demanding Next-Gen PC Games

Frankly, that’s shocking. I don’t remember the last time that I’ve seen a game that requires 12 GB of RAM at a minimum or a game that demanded a GTX 1060 (which is still a pretty powerful modern GPU) just to run. While it’s true that neither the minimum nor recommended requirements will require you to purchase the latest and greatest GPUs and CPUs, you’re seemingly going to need a gaming PC that’s only a few years “old” to run the game at all.

So are Godfall‘s specs a preview of what kind of PC you’re going to need to get through at least the next few years of gaming? Maybe, but some are already speculating that these requirements have more to do with Godfall‘s PC port than the future of gaming.

Again, these are incredibly high requirements that were revealed relatively late in relation to Godfall‘s

Ancient tools hint that Neanderthals lived on Danish island 120,000 years ago

Ancient flint tools buried in the slopes of a Danish island have offered a hint that Neanderthals may have lived there 120,000 years ago. 

The first humans in Denmark were previously believed to have been reindeer hunters from around 14,000 years ago.

Archaeologists from Denmark’s National Museum and Roskilde Museum excavated slopes in Ejby Klint by Isefjord between Roskilde and Holbæk.

The researchers found ancient mussel shells and flint stones that may have been shaped by humans. 

Ejby Klint is one of the few places in Denmark where archaeologists can easily find layers in the earth from a warm period between two ice ages 115,000-130,000 years ago.
