Meet the first Neanderthal family      (via sciencedaily.com) 

Researchers have managed to sequence multiple individuals from a remote Neanderthal community in Siberia. Among these thirteen individuals, the researchers identified multiple related individuals -- among these a father and his teenage daughter. The researchers were also able to use the thirteen genomes to provide a glimpse into the social organization of a Neanderthal community. They appear to have been a small group of close relatives, consisting of ten to twenty members, and communities were primarily connected through female migration.

Land in a cyclone's wake becomes more vulnerable to forest fires      (via sciencedaily.com)     Original source 

The strong winds and torrential rains that accompany a cyclone do tremendous damage to ecosystems, and this damage can make them more prone to future wildfires. As intense cyclones are projected to become more frequent worldwide, a team of researchers examines the links between cyclones and forest fires, how they fuel one another, and why we may see fires burning in unlikely places in the future.

Race against time to find ancient Indigenous carvings on boab trees      (via sciencedaily.com) 

Carvings in boab trees are as significant as rock art for Indigenous Australians. Now, there is a race against time to document the ancient art in the bark of boabs before the remarkable heritage trees die.

Geneticists discover new wild goat subspecies via ancient DNA      (via sciencedaily.com) 

Geneticists have discovered a previously unknown lineage of wild goats over ten millennia old. The new goat type, discovered from genetic screening of bone remains and referred to as 'the Taurasian tur', likely survived the Last Glacial Maximum (the ice age), which stranded their ancestors in the high peaks of the Taurus Mountains in Turkey where their remains were found.

Warmer stream temperatures in burned-over Oregon watershed didn't result in fewer trout      (via sciencedaily.com) 

The number of trout in a southern Oregon stream system showed no decline one year after a fire burned almost the entire watershed, including riparian zone trees that had helped maintain optimal stream temperatures for the cold-water fish.

The neighbors of the caliph: Archaeologists uncover ancient mosaics on the shore of the Sea of Galilee      (via sciencedaily.com) 

With the help of geomagnetic surface surveys and subsequent hands-on digging, an excavation team has revealed new insights into the area in which the caliph's palace of Khirbat al-Minya was built on the shores of the Sea of Galilee. According to these findings, there had already been a settlement occupied by Christian or Jewish inhabitants in the immediate vicinity long before the palace was built.

Among ancient Mayas, cacao was not a food exclusive to the elite      (via sciencedaily.com) 

It was the money that grew on trees. Said to be a gift from the gods, cacao for the ancient Maya was considered sacred, used not only as currency, but in special ceremonies and religious rituals. It's the progenitor plant of chocolate, and notions of luxury are embedded in its lore.

Indoor air quality experiments show exposure risks while cooking, cleaning      (via sciencedaily.com) 

When you're cooking or cleaning inside your home, what chemicals are you breathing, and are they potentially harmful? Chemists have given us a solid start on the answer. A large, collaborative research experiment recently attempted to map the airborne chemistry of a typical home. Researchers performed typical home activities like cooking and cleaning and used sophisticated instrumentation to document the chemistry that resulted.

Scientists find evidence for food insecurity driving international conflict two thousand years ago      (via sciencedaily.com) 

Researchers have identified climate-driven changes to food availability as a factor behind dramatic historical events that led the oasis city of Palmyra in Syria to its ultimate demise.

Now you don't have to wait for smoke to know where fires are likely to occur      (via sciencedaily.com) 

Scientists have developed a way to forecast which of the Great Basin's more than 60 million acres have the highest probability of a large rangeland fire. The forecasts come from a model developed by the researchers that combines measures of accumulated annual and perennial grass vegetation that is potential fire fuel with recent weather and climate data. When integrated, this information can be translated into maps showing the likelihood of a large wildfire -- greater than 1,000 acres--across the Great Basin. These forecasts also can be scaled down to predict fire risk for counties or even single pastures.

The anglo-saxon migration: New insights from genetics      (via sciencedaily.com) 

In the largest early-medieval population study to date, an interdisciplinary team consisting of geneticists and archaeologists analyzed over 400 individuals from ancient Britain, Ireland, Germany, Denmark and the Netherlands. The results show in detail one of the largest population transformations in the post-Roman world.

Modern humans generate more brain neurons than Neanderthals      (via sciencedaily.com) 

The question of what makes modern humans unique has long been a driving force for researchers. Comparisons with our closest relatives, the Neanderthals, therefore provide fascinating insights. The increase in brain size, and in neuron production during brain development, are considered to be major factors for the increased cognitive abilities that occurred during human evolution. However, while both Neanderthals and modern humans develop brains of similar size, very little is known about whether modern human and Neanderthal brains may have differed in terms of their neuron production during development. Researchers now show that the modern human variant of the protein TKTL1, which differs by only a single amino acid from the Neanderthal variant, increases one type of brain progenitor cells, called basal radial glia, in the modern human brain.
