Archaeology: Prehistoric violence at Jebel Sahaba may not have been single event

2021-05-27
(Press-News.org) Reanalysis of the prehistoric cemetery Jebel Sahaba (Sudan), one of the earliest sites showing human warfare (13,400 years ago), suggests that hunter-fisher-gatherers engaged in repeated, smaller conflicts. The findings are published in Scientific Reports. Healed trauma on the skeletons found in the cemetery indicates that individuals fought and survived several violent assaults, rather than fighting in one fatal event as previously thought.

Isabelle Crevecoeur and colleagues reanalysed the skeletal remains of 61 individuals, who were originally excavated in the 1960s, using newly available microscopy techniques. The authors identified 106 previously undocumented lesions and traumas, and were able to distinguish between projectile injuries (from arrows or spears), trauma (from close combat), and traces associated to natural decay. They found 41 individuals (67%) buried in Jebel Sahaba had at least one type of healed or unhealed injury. In the 41 individuals with injuries, 92% had evidence of these being caused by projectiles and close combat trauma, suggesting interpersonal acts of violence.

The authors suggest that the number of healed wounds matches sporadic and recurrent acts of violence, which were not always lethal, between Nile valley groups at the end of the Late Pleistocene (126,000 to 11,700 years ago). They speculate these may have been repeated skirmishes or raids between different groups. At least half of the injuries were identified as puncture wounds, caused by projectiles like spears and arrows, which supports the authors' theory that these injuries happened when groups attacked from a distance, rather than during domestic conflicts.

Icebergs push back

Icebergs push back
2021-05-27
Shortly before Jakobshavn Isbræ, a tidewater glacier in Greenland, calves massive chunks of ice into the ocean, there's a sudden change in the slushy collection of icebergs floating along the glacier's terminus, according to a new paper led by the Cooperative Institute for Research in Environmental Sciences (CIRES) at CU Boulder. The work, published in Nature Geoscience, shows that a relaxation in the thick aggregate of icebergs floating at the glacier-ocean boundary occurs up to an hour before calving events. This finding may help scientists better understand future sea-level rise scenarios and could also help ...

Jebel Sahaba: A succession of violence rather than a prehistoric war

Jebel Sahaba: A succession of violence rather than a prehistoric war
2021-05-27
Since its discovery in the 1960s, the Jebel Sahaba cemetery (Nile Valley, Sudan), 13 millennia old, was considered to be one of the oldest testimonies to prehistoric warfare. However, scientists from the CNRS and the University of Toulouse - Jean Jaurès (1) have re-analysed the bones preserved in the British Museum (London) and re-evaluated their archaeological context. The results, published in Scientific Reports on May 27, 2021, show that it was not a single armed conflict but rather a succession of violent episodes, probably exacerbated by climate change. Many individuals buried at Jebel Sahaba bear injuries, half ot them caused by projectiles, the points of which were found in the bones or the fill where the body was located. The ...

Myocarditis in big ten athletes with recent SARS-CoV-2 infection

2021-05-27
What The Study Did: In this study of 1,597 Big Ten athletes who had comprehensive cardiac screening, including cardiac magnetic resonance (CMR) imaging, after COVID-19 infection, 37 athletes (2.3%) were diagnosed with clinical and subclinical myocarditis. Researchers report CMR screening increased detection of myocarditis, a leading cause of sudden death in competitive athletes. Authors: Curt J.Daniels, M.D., and Saurabh Rajpal, M.B.B.S., M.D., of Ohio State University in Columbus, are the corresponding authors.

How metals work together to weaken hardy nitrogen-nitrogen bonds

2021-05-27
CAMBRIDGE, MA -- Nitrogen, an element that is essential for all living cells, makes up about 78 percent of Earth's atmosphere. However, most organisms cannot make use of this nitrogen until it is converted into ammonia. Until humans invented industrial processes for ammonia synthesis, almost all ammonia on the planet was generated by microbes using nitrogenases, the only enzymes that can break the nitrogen-nitrogen bond found in gaseous dinitrogen, or N2. These enzymes contain clusters of metal and sulfur atoms that help perform this critical reaction, but the mechanism of how they do so is not well-understood. For the first time, MIT chemists have now determined the structure of a complex that forms when N2 binds to these clusters, and they discovered that the clusters are able to weaken ...

Roots of major depression revealed in all its genetic complexity

2021-05-27
A massive genome-wide association study (GWAS) of genetic and health records of 1.2 million people from four separate data banks has identified 178 gene variants linked to major depression, a disorder that will affect one of every five people during their lifetimes. The results of the study, led by the U.S. Department of Veterans Affairs (V.A.) researchers at Yale University School of Medicine and University of California-San Diego (UCSD), may one day help identify people most at risk of depression and related psychiatric disorders and help doctors prescribe drugs best suited to treat the disorder. The study was published May 27 in the journal Nature Neuroscience. For the ...

Gene research on brassicas provides potential for making better crops

2021-05-27
The research - by the University of York - gives scientists a new tool that will support the development of new varieties. The research led to scientists being able to develop an adaptable framework for describing gene content and order across all Brassica species. Lead author, Professor Ian Bancroft, Chair of Plant Genomics at the Centre for Novel Agricultural Products (CNAP), at the Department of Biology said: "The research has helped us understand the trajectory of how genomes evolve in brassicas. We can use this new knowledge, for example, to accelerate the exchange of beneficial genes between Brassica species." Brassica vegetables, such as broccoli, cabbage, kale, pak choi and swede, along with brassica oil crops such as ...

Delaying lung cancer surgery associated with higher risk of recurrence, death

2021-05-27
Swiftness is essential when treating lung cancer, the second most common type of cancer in the U.S. and the country's leading cause of cancer deaths. For patients with early-stage non-small cell lung cancer, surgical removal of a tumor-infested lung or of a smaller lung section may be the only treatment needed. However, some patients postpone surgery while seeking second opinions, because of economic or social factors, or for personal reasons such as waiting until after a child's wedding or a planned vacation. Worries about contracting COVID-19 in a clinical setting also have led to delays. But a new study by researchers at Washington University School of Medicine ...

New framework to enhance national climate action and achieve global goals

New framework to enhance national climate action and achieve global goals
2021-05-27
With the COP Climate conference in Glasgow only a few months away, the ambitions of the Paris Agreement and the importance of taking action at the national level to reach global climate goals is returning to the spotlight. IIASA researchers and colleagues have proposed a novel systematic and independent scenario framework that could help policymakers assess and compare climate policies and long-term strategies across countries to support coordinated global climate action. The Paris Agreement defines a long-term temperature goal for international climate policy: "holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C". Its achievement critically ...
