Our future climate depends partly on soil microbes -- but how are they affected by climate change?      (via sciencedaily.com)     Original source 

The largest terrestrial carbon sink on Earth is the planet's soil. One of the big fears is that a warming planet will liberate significant portions of the soil's carbon, turning it into carbon dioxide (CO2) gas, and so further accelerate the pace of planetary warming. A key player in this story is the microbe, the predominant form of life on Earth, and which can either turn organic carbon -- the fallen leaves, rotting tree stumps, dead roots and other organic matter -- into soil, or release it into the atmosphere as CO2. Now, an international team of researchers has helped to untangle one of the knottiest questions involving soil microbes and climate change: what effect does a warming planet have on the microbes' carbon cycling?

How the last 12,000 years have shaped what humans are today      (via sciencedaily.com) 

While humans have been evolving for millions of years, the past 12,000 years have been among the most dynamic and impactful for the way we live today, according to an anthropologist.

Marriage in Minoan Crete      (via sciencedaily.com) 

An international team of researchers achieves completely new insights into Bronze Age marriage rules and family structures in Greece. Analyses of ancient genomes show that the choice of marriage partners was determined by one's own kinship.

Ancient Siberian genomes reveal genetic backflow from North America across the Bering Sea      (via sciencedaily.com) 

The movement of people across the Bering Sea from North Asia to North America is a well-known phenomenon in early human history. Nevertheless, the genetic makeup of the  people who lived in North Asia during this time has remained mysterious due to a limited number of ancient genomes analyzed from this region. Now, researchers describe genomes from ten individuals up to 7,500 years old that help to fill the gap and show geneflow from people moving in the opposite direction from North America to North Asia.

Ethical ancient DNA research must involve descendant communities, say researchers      (via sciencedaily.com) 

The analysis of ancient DNA allows scientists to trace human evolution and make important discoveries about modern populations. The data revealed by ancient DNA sampling can be valuable, but the human remains that carry this ancient DNA are often those of the ancestors of modern Indigenous groups, and some communities have expressed concerns about the ethics of sampling by outside parties. A group of scientists make the case for involvement of descendant communities in all aspects of the research process.

Landscaping for drought: We're doing it wrong      (via sciencedaily.com)     Original source 

Despite recent, torrential rains, most of Southern California remains in a drought. Accordingly, many residents plant trees prized for drought tolerance, but a new study shows that these trees lose this tolerance once they're watered.

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.

New York City's greenery absorbs a surprising amount of its carbon emissions      (via sciencedaily.com)     Original source 

A study of vegetation across New York City and some densely populated adjoining areas has found that on many summer days, photosynthesis by trees and grasses absorbs all the carbon emissions produced by cars, trucks and buses, and then some. The surprising result, based on new hyper-local vegetation maps, points to the underappreciated importance of urban greenery in the carbon cycle.

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.
