Towards efficient lithium--air batteries with solution plasma-based synthesis of perovskite hydroxide catalysts      (via sciencedaily.com)     Original source 

CoSn(OH)6 (CSO) is an effective oxygen evolution reaction (OER) catalyst, necessary for developing next-generation lithium -- air batteries. However, current methods of synthesizing CSO are complicated and slow. Recently, an international research team synthesized CSO in a single step within 20 minutes using solution plasma to generate CSO nanocrystals with excellent OER catalytic properties. Their findings could boost the manufacturing of high energy density batteries.

Lessons in sustainability, evolution and human adaptation -- courtesy of the Holocene      (via sciencedaily.com)     Original source 

The El Gigante rockshelter in western Honduras is among only a handful of archaeological sites in the Americas that contain well-preserved botanical remains spanning the last 11,000 years. Considered one of the most important archaeological sites discovered in Central America in the last 40 years, El Gigante was recently nominated as a UNESCO World Heritage site.

Cave excavation pushes back the clock on early human migration to Laos      (via sciencedaily.com)     Original source 

Fifteen years of archaeological work in the Tam Pa Ling cave in northeastern Laos has yielded a reliable chronology of early human occupation of the site. The team's excavations through the layers of sediments and bones that gradually washed into the cave and were left untouched for tens of thousands of years reveals that humans lived in the area for at least 70,000 years -- and likely even longer.

Face of Anglo-Saxon teen VIP revealed with new evidence about her life      (via sciencedaily.com)     Original source 

The face of a 16-year-old woman buried near Cambridge (UK) in the 7th century with an incredibly rare gold and garnet cross (the 'Trumpington Cross') has been reconstructed following analysis of her skull. The striking image is going on public display for the first time on 21st June, with new scientific evidence showing that she moved to England from Central Europe as a young girl, leading to an intriguing change in her diet.

Climate change likely led to violence in early Andean populations      (via sciencedaily.com)     Original source 

Climate change in current times has created problems for humans such as wildfires and reduced growing seasons for staple crops, spilling over into economic effects. Many researchers predict, and have observed in published literature, an increase in interpersonal violence and homicides when temperatures increase. Violence during climatic change has evidence in history, anthropology researchers say.

The Viking disease can be due to gene variants inherited from Neanderthals      (via sciencedaily.com)     Original source 

Many men in northern Europe over the age of 60 suffer from the so-called Viking disease, which means that the fingers lock in a bent position. Now researchers have used data from over 7,000 affected individuals to look for genetic risk factors for the disease. The findings show that three of the strongest risk factors are inherited from Neanderthals.
