Smallpox has plagued humans since ancient Egyptian times, new evidence confirms      (via sciencedaily.com)     Original source 

Smallpox was once one of humanity's most devastating diseases, but its origin is shrouded in mystery. For years, scientific estimates of when the smallpox virus first emerged have been at odds with historical records. Now, a new study reveals that the virus dates back 2,000 years further than scientists have previously shown, verifying historical sources and confirming for the first time that the disease has plagued human societies since ancient times.

Study reveals average age at conception for men versus women over past 250,000 years      (via sciencedaily.com) 

Using a new method based upon comparing DNA mutation rates between parents and offspring, evolutionary biologists have revealed the average age of mothers versus fathers over the past 250,000 years, including the discovery that the age gap is shrinking, with women's average age at conception increasing from 23.2 years to 26.4 years, on average, in the past 5,000 years.

DNA from archaeological remains shows that immigration to Scandinavia was exceptional during the Viking period      (via sciencedaily.com) 

A new study based on 297 ancient Scandinavian genomes analysed together with the genomic data of 16,638 present day Scandinavians resolve the complex relations between geography, ancestry, and gene flow in Scandinavia -- encompassing the Roman Age, the Viking Age and later periods. A surprising increase of variation during the Viking period indicates that gene flow into Scandinavia was especially intense during this period.

Bering Land Bridge formed surprisingly late during last ice age      (via sciencedaily.com) 

A new study that reconstructs the history of sea level at the Bering Strait shows that the Bering Land Bridge connecting Asia to North America did not emerge until around 35,700 years ago, less than 10,000 years before the height of the last ice age (known as the Last Glacial Maximum). The findings indicate that the growth of the ice sheets -- and the resulting drop in sea level -- occurred surprisingly quickly and much later in the glacial cycle than previous studies had suggested.

When using virtual reality as a teaching tool, context and 'feeling real' matter      (via sciencedaily.com) 

Psychologists had people learn words from two phonetically similar languages in virtual reality environments. Those who learned each language in its own unique context mixed up fewer words and were able to recall 92% of the words they had learned. In contrast, participants who had learned both sets of words in the same VR context were more likely to confuse terms between the two languages and retained only 76% of the words. Regardless of group, those participants who felt immersed in the VR world remembered more than those who did not feel immersed.

Drought encouraged Attila's Huns to attack the Roman empire, tree rings suggest      (via sciencedaily.com) 

Hunnic peoples migrated westward across Eurasia, switched between farming and herding, and became violent raiders in response to severe drought in the Danube frontier provinces of the Roman empire, a new study argues.

Researchers develop wireless, ultrathin 'Skin VR' to provide a vivid, 'personalized' touch experience in the virtual world      (via sciencedaily.com) 

Enhancing the virtual experience with the touch sensation has become a hot topic, but today's haptic devices remain typically bulky and tangled with wires. Researchers have now developed an advanced wireless haptic interface system, called WeTac, worn on the hand, which has soft, ultrathin soft features, and collects personalized tactile sensation data to provide a vivid touch experience in the metaverse.

Improving the accuracy of markerless gait analysis      (via sciencedaily.com) 

Gait analysis systems measure certain metrics to give their results. These results then drive clinical treatment for gait correction. However, detailed gait analysis requires expensive equipment, and a lot of space, markers, time. Measurements from markerless, video-based gait analysis systems, on the other hand, are inaccurate. To improve upon existing systems, researchers have now combined RGB camera-based pose estimation and an inertial measurement unit sensor for gait analysis. This significantly reduces errors in the process.

Devastating megafires are becoming more common, in part, because the planet is warming. But a new study suggests bringing 'good fire' back to the U.S. and other wildfire fire-prone areas, as Native Americans once did, could potentially blunt the role of climate in triggering today's wildfires.

For over a century, one of the earliest human fossils ever discovered in Spain has been long considered a Neanderthal. However, new analysis from an international research team dismantles this century-long interpretation, demonstrating that this fossil is not a Neanderthal; rather, it may actually represent the earliest presence of Homo sapiens ever documented in Europe.
