Seeing the wood for the trees: How archaeologists use hazelnuts to reconstruct ancient woodlands
If we could stand in a landscape that our Mesolithic ancestors called home, what would we see around us? Scientists have devised a method of analyzing preserved hazelnut shells to tell us whether the microhabitats around archaeological sites were hea.....»»
Ancient Mars" thick crust could have supported hidden water reservoirs and rare magmas, new research suggests
A new study explores how variations in Mars' crustal thickness during its ancient history may have influenced the planet's magmatic evolution and hydrological systems. The research, published in Earth and Planetary Science Letters, suggests that the.....»»
Extended chart of life shows ancient species may have evolved slower and lasted longer
If all the world's a stage and all the species merely players, then their exits and entrances can be found in the rock record. Fossilized skeletons and shells clearly show how evolution and extinction unfolded over the past half a billion years, but.....»»
Ancient clay remedy may have potential to boost modern gut health
A team of scientists has discovered that an ancient medicinal clay known as Lemnian earth (LE) could inspire new understanding of how to support present-day gut health......»»
25 years after Lothar: How the windstorm rebuilt Swiss forests
On the morning of December 26, 1999, the winter storm "Lothar" swept across Switzerland, knocking down around 14 million cubic meters of wood, three times the annual logging volume. WSL experts answer numerous questions about how the forest is doing.....»»
How the loss of urban trees affects education outcomes
It's well established that urban tree cover provides numerous environmental and psychological benefits to city dwellers. Urban trees may also bolster education outcomes and their loss could disproportionately affect students from low-income families,.....»»
Wildfire risk climbs as trees reclaim eastern US landscapes
The eastern U.S. has more trees and shrubs than three decades ago. This growth, driven by processes such as tree and understory infilling in unmanaged forests, is helping fuel wildfires, contributing to changing fire regimes in the eastern half of th.....»»
Black hole genealogy: A new way to discover "ancestors" of cosmic phenomena
A research team has proposed a new method to reconstruct the "family tree" of black holes. Published in The Astrophysical Journal, this research offers a way to infer the properties of the black hole progenitors of these mergers, one of the most brut.....»»
Study reveals untapped potential in Switzerland"s wood material flows
Switzerland has set itself a goal that is as ambitious as it is necessary: net zero by 2050. One of the most important raw materials on the road to a climate-neutral future is wood. This renewable natural resource binds CO2 from the atmosphere as it.....»»
Twins were the norm for our ancient primate ancestors—one baby at a time had evolutionary advantages
Twins have been rare in human history and for that reason can seem special. Many cultures associate twins with health and vitality, while others see them as a philosophical reminder of the duality of life and death, good and evil. Some famous twins a.....»»
Butchered bones suggest violent "othering" of enemies in Bronze Age Britain
Archaeologists have analyzed more than 3,000 human bones and bone fragments from the Early Bronze Age site of Charterhouse Warren, England, concluding that the people were massacred, butchered, and likely partly consumed by enemies as a means to dehu.....»»
Ancient genes pinpoint when humans and Neanderthals mixed and mingled
Neanderthals and humans likely mixed and mingled during a narrow time frame 45,000 years ago, scientists reported Thursday......»»
Archaeological study uncovers world"s oldest evidence of livestock horn manipulation
Archaeologists Dr. Wim van Neer, Dr. Bea De Cupere, and Dr. Renée Friedman have published a study on the earliest evidence of horn modification in livestock in the Journal of Archaeological Science......»»
Saturday Citations: M87* lashes out; a deep sleep discovery; proposal to build a digital cell
I love it when researchers observe an extra-weird particle, and this week, scientists reported the observation of a particle that only has mass when it's moving in a single direction. Good enough! An ancient DNA analysis suggests that Neanderthals an.....»»
Buried landforms reveal North Sea"s ancient glacial past
An international team of researchers, including a glaciologist at Newcastle University, UK, has discovered remarkably well-preserved glacial landforms buried almost 1 km beneath the North Sea......»»
Ancient Roman harbor wooden structures analyzed with MRI technology
In a recent study, rare wooden structures from the Roman Empire were investigated in a wide range of ways using NMR methods. These methods, widely known for their use in hospital MRI scans to produce detailed images of the human body, have proven equ.....»»
How an iconic desert tree survives extreme heat—and the unique risk it"s facing now
New research has found that the punishing summer temperatures and persistent drought conditions in much of Arizona and the Southwest are dealing a double whammy to trees attempting to regulate their own temperature, putting a critical part of the des.....»»
How Australia"s ancient forests became an arid zone
I didn't plan to become a botanist, I just pursued activities that made me happy. Studying subjects that make you light up can guide you towards a career that doesn't really feel like work because you find it fascinating......»»
Neanderthal-human interbreeding lasted 7,000 years, new study reveals
A new analysis of DNA from ancient modern humans (Homo sapiens) in Europe and Asia has determined, more precisely than ever, the time period during which Neanderthals interbred with modern humans, starting about 50,500 years ago and lasting about 7,0.....»»
Ancient genomes link early Europeans to Neanderthal ancestry
After modern humans left Africa, they met and interbred with Neanderthals, resulting in around 2–3% Neanderthal DNA that can be found in the genomes of all people outside Africa today. However, little is known about the genetics of these first pion.....»»
How to catch a supernova explosion before it happens—and what we can learn from it
Stars are born, live and die in spectacular ways, with their deaths marked by one of the biggest known explosions in the universe. Like a campfire needs wood to keep burning, a star relies on nuclear fusion—primarily using hydrogen as fuel—to gen.....»»
