High resolution techniques reveal clues in 3.5 billion-year-old biomass
High resolution techniques reveal clues in 3.5 billion-year-old biomass
Research team analyses organic material from the early Earth tracing its origin and composition To learn about the first organisms on our planet, researchers have to analyse the rocks of the early Earth. These can only be found in a few places on the surface of the Earth. The Pilbara Craton in Western Australia is one of these rare sites: there are rocks there that are around 3.5 billion years old containing traces of the microorganisms that lived at that time.

How humans cause earthquakes
How humans cause earthquakes
Geophysicists from Freie Universität Berlin among the researchers investigating human-induced earthquakes. It is common knowledge that humans have a big effect on the world and their natural environment. However, what may be less well-known is that humans can also induce earthquakes. Industrial activities such as geothermal energy production, fracking for oil and natural gas, and wastewater disposal can all lead to increased seismic activity that commonly takes the form of earthquakes.

How forests smell - a risk for the climate?
Plants emit odours for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers from Leipzig University, the Leibniz Institute for Tropospheric Research (TROPOS) and the German Centre for Integrative Biodiversity Research (iDiv) carried out a study to investigate how biodiversity influences the emission of these substances.

Early Humans in the Paleolithic Age: More Than Just Game on the Menu
Early Humans in the Paleolithic Age: More Than Just Game on the Menu
In a study published in the journal "Scientific Reports," researchers from the Senckenberg Centre for Human Evolution and Palaeoenvironment (SHEP) at the University of Tübingen show that early humans of the Middle Paleolithic had a more varied diet than previously assumed. The analysis of a site in the Zagros Mountains in Iran reveals that around 81,000 to 45,000 years ago, the local hominins hunted ungulates as well as tortoises and carnivores.

Keeping an eye on the regions when it comes to climate change
Keeping an eye on the regions when it comes to climate change
Up to now, the results of climate simulations have sometimes contradicted the analysis of climate traces from the past. A team led by the physicist Thomas Laepple from the Alfred Wegener Institute in Potsdam and the climatologist Kira Rehfeld from the University of Tübingen has therefore brought together experts in climate models and climate tracks to clarify how the discrepancies come about.

How the Greenland ice sheet can be saved
Climate research: New findings on temperature tipping points Climate researchers around the world are sounding the alarm about exceeding critical temperature values on the Earth. If temperatures pass what are called tipping points, the results could be catastrophic. An international team of researchers, including members from the Technical University of Munich (TUM), has now demonstrated in simulations that the temperature tipping point for the Greenland ice sheet can be exceeded in certain cases for a short time, as long as extreme countermeasures are taken afterwards.
