When three species of human ancestor walked the Earth
Scientists share details of the most ancient fossil of Homo erectus known and discuss how these new findings are forcing us to rewrite a part of our species’ evolutionary history.
Uncertain climate future could disrupt energy systems
(DOE/Lawrence Berkeley National Laboratory) An international team of scientists has published a new study proposing an optimization methodology for designing climate-resilient energy systems and to help ensure that communities will be able to meet future energy needs given weather and climate variability. Their findings were recently published in Nature Energy.
What is dark energy?
Dark energy is one of the great unsolved mysteries of cosmology. It’s now thought to make up 68% of everything in the universe.
Mimosa, 2nd-brightest in Southern Cross
To see Mimosa, you need to be at the latitude of New Orleans, Hawaii, Cairo or New Delhi. From the Southern Hemisphere, Mimosa is a prominent and beloved star.
Was this the ancestor of all animals?
Geologists say the worm-like creature – about the size of a grain of rice – is the 1st ancestor on the family tree that contains most animals today, including humans.
In Earth’s largest extinction, land animal die-offs began long before marine extinction
Because of poor dates for land fossils laid down before and after the mass extinction at the end of the Permian, paleontologists assumed that the terrestrial extinctions from Gondwana occurred at the same time as the better-documented marine extinctions. But a new study provides more precise dates for South African fossils and points to a long, perhaps 400,000-year period of extinction on land before the rapid marine extinction 252 million years ago.
Sorry, but the Virus Shows Why There Won’t Be Global Action on Climate Change – Foreign Policy

The 2020 HFSP Fellowships
(Human Frontier Science Program) HFSP raises the value of its fellowship awards granted to 65 young researchers who will challenge traditional thinking by investigating behavioural computation, genomics of fear memories, the dynamics of the blood stem cell niche, or building a new super-resolution microscope.
BBC Admits: Green Energy Plants Threaten Wildlife Habitats
Wind, solar and hydropower installations pose a growing threat to key conservation areas, say researchers. Researchers found that over 2,200 green energy plants have been built within the boundaries of the Earth’s remaining wilderness. They say that around 17% of…
