The beginnings of fashion      (via sciencedaily.com)     Original source 

A team of researchers suggest that eyed needles were a new technological innovation used to adorn clothing for social and cultural purposes, marking the major shift from clothes as protection to clothes as an expression of identity.

Why the harsh Snowball Earth kick-started our earliest multicellular ancestors      (via sciencedaily.com)     Original source 

Why did multicellularity arise? Solving that mystery may help pinpoint life on other planets and explain the vast diversity and complexity seen on Earth today, from sea sponges to redwoods to human society. A new article shows how specific physical conditions -- especially ocean viscosity and resource deprivation -- during the global glaciation period known as Snowball Earth could have driven eukaryotes to turn multicellular.

Wildfires increasingly threaten oil and gas drill sites, compounding potential health risks      (via sciencedaily.com)     Original source 

More than 100,000 oil and gas wells across the western U.S. are in areas burned by wildfires in recent decades, a new study has found, and some 3 million people live next to wells that in the future could be in the path of fires worsened by climate change.

Fuel treatments reduce future wildfire severity      (via sciencedaily.com)     Original source 

There is a common belief that prescribed burning, thinning trees, and clearing underbrush reduce risks of the severity of future fires. But is that true? A new project analyzing 40 studies where wildfire burned into different vegetation treatments, spanning 11 western states. Researchers found overwhelming evidence that in seasonally dry mixed conifer forests in the western U.S., reducing surface and ladder fuels and tree density through thinning, coupled with prescribed burning or pile burning, could reduce future wildfire severity by more than 60% relative to untreated areas.

Origins of cumulative culture in human evolution      (via sciencedaily.com)     Original source 

Cumulative culture -- the accumulation of technological modifications and improvements over generations -- allowed humans to adapt to a diversity of environments and challenges. But, it is unclear when cumulative culture first developed during hominin evolution. A new study concludes that humans began to rapidly accumulate technological knowledge through social learning around 600,000 years ago.

Direct evidence found for dairy consumption in the Pyrenees in the earliest stages of the Neolithic      (via sciencedaily.com)     Original source 

A study on the remains of the Chaves and Puyascada caves, both located in the province of Huesca, Spain, yields the first direct proof of the consumption and processing of dairy products in the Pyrenees already at the start of the Neolithic period, approximately 7,500 years ago, as well as the consumption of pig. The results lead to doubts about the belief that these products were first used much later in the Pyrenean mountain range.

Ancient polar sea reptile fossil is oldest ever found in Southern Hemisphere      (via sciencedaily.com)     Original source 

An international team of scientists has identified the oldest fossil of a sea-going reptile from the Southern Hemisphere -- a nothosaur vertebra found on New Zealand's South Island. 246 million years ago, at the beginning of the Age of Dinosaurs, New Zealand was located on the southern polar coast of a vast super-ocean called Panthalassa. 'The nothosaur found in New Zealand is over 40 million years older than the previously oldest known sauropterygian fossils from the Southern Hemisphere.

New way to spot beetle-killed spruce can help forest, wildfire managers      (via sciencedaily.com)     Original source 

A new machine-learning system can automatically produce detailed maps from satellite data to show locations of likely beetle-killed spruce trees in Alaska, even in forests of low and moderate infestation where identification is otherwise difficult. The automated process can help forestry and wildfire managers in their decisions. That's critical as the beetle infestation spreads.

Ancient Syrian diets resembled the modern 'Mediterranean diet'      (via sciencedaily.com)     Original source 

Thousands of years ago, people in ancient Syria likely ate mostly grains, grapes, olives and a small amount of dairy and meat -- similar to today's 'Mediterranean diet,' according to a new study.

Ritual sacrifice at Chichén Itzá      (via sciencedaily.com)     Original source 

Rising to power in the wake of the Classic Maya collapse, Chichen Itz was among the largest and most influential cities of the ancient Maya, but much about its political connections and ritual life remain poorly understood. Close kin relationships, including two pairs of identical twins, suggests a connection to the Maya origin myths of the Popol Vuh.

Scientists unlock secrets of how archaea, the third domain of life, makes energy      (via sciencedaily.com)     Original source 

An international scientific team has redefined our understanding of archaea, a microbial ancestor to humans from two billion years ago, by showing how they use hydrogen gas. The findings explain how these tiny lifeforms make energy by consuming and producing hydrogen. This simple but dependable strategy has allowed them to thrive in some of Earth's most hostile environments for billions of years.

Shedding light on the origin of a genetic variant underlying fungal infections      (via sciencedaily.com)     Original source 

Variants in the CARD9 gene increase susceptibility to severe fungal infections. However, individuals in different parts of the world tend to carry specific CARD9 variants, making it complex to track the origin of these mutations. In a recent study, a research team conducted genetic analyses on Japanese, Korean, and Chinese patients, revealing that they all shared a variant of CARD9 stemming from a common ancestor from less than 4,000 years ago.
