Charting the expansion history of the universe with supernovae

An international research team analyzed a database of more than 1000 supernova explosions and found that models for the expansion of the Universe best match the data when a new time dependent variation is introduced. If proven ...

Few realistic scenarios left to limit global warming to 1.5°C

Of the over 400 climate scenarios assessed in the 1.5°C report by the Intergovernmental Panel on Climate Change (IPCC), only around 50 scenarios avoid significantly overshooting 1.5°C. Of those only around 20 make realistic ...

New cyanobacteria species spotlights early life

Cyanobacteria are one of the unsung heroes of life on Earth. They first evolved to perform photosynthesis about 2.4 billion years ago, pumping tons of oxygen into the atmosphere—a period known as the Great Oxygenation Event—which ...

New research shows: Antoni van Leeuwenhoek led rivals astray

A microscope used by Antoni van Leeuwenhoek to conduct pioneering research contains a surprisingly ordinary lens, as new research by Rijksmuseum Boerhaave Leiden and TU Delft shows. It is a remarkable finding, because Van ...

Solar wind from the center of the Earth

High-precision noble gas analyses indicate that solar wind particles from our primordial Sun were encased in the Earth's core over 4.5 billion years ago. Researchers from the Institute of Earth Sciences at Heidelberg University ...

Is the past (and future) there when nobody looks?

In 1961, the Nobel prize winning theoretical physicist Eugene Wigner proposed what is now known as the 'Wigner's friend' thought experiment as an extension of the notorious Schroedinger's cat experiment. In the latter, a ...
