How does an ecosystem distribute its energy across body sizes? A new study suggests the answer depends on where you are—and how much humans have altered the landscape. Analyzing communities of birds and mammals worldwide, ...
Nasa is developing ways to use nuclear power to send spacecraft to their destinations. Nuclear propulsion could greatly reduce the journey time to Mars, perhaps cutting a voyage of more than six months to three or four months.
There are tens of thousands of near-Earth objects (NEOs) that represent some of the most easily accessible resources in the solar system. Planning trajectories to rendezvous with these miniature worlds is notoriously difficult, ...
Some historical events are so catastrophic they resist comprehension. And yet they compel us to try to understand them, again and again.
For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic manipulation. The models ...
A joint theoretical study by the University of Innsbruck and Zhejiang University has uncovered the microscopic origin of a striking quantum phenomenon: a periodically driven gas of ultracold atoms that simply refuses to heat ...
Alena Tensor is a relatively new mathematical approach that allows for arbitrary curving and straightening of analyzed spacetimes. As it turns out, generalizing this model to all known fields and fully describing matter, ...
At Empa, an interdisciplinary research institute for materials science and technology within the ETH Domain, researchers are working on ways to kill harmful bacteria and viruses. In the Nanomaterials in Health Lab, headed ...
The most common side effects of mRNA vaccines like the COVID-19 shot are well known: soreness, mild fever, and general malaise. Those symptoms, which typically resolve within days, are the natural result of the immune system ...
A new study published in Nature Astronomy indicates that the dense, star- and dark-matter–rich environments around supermassive black hole binaries pack on the order of a million solar masses into each cubic parsec. The team ...
