Phys.org / Gravitational wave signal tests Einstein's theory of general relativity

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers an opportunity to test ...

Phys.org / Farm waste could lock away carbon for decades

Agricultural waste that is usually burned or left to rot could play a far bigger role in tackling climate change if it were instead used in long-lasting building materials, according to new research from the University of ...

Phys.org / Imaging the Wigner crystal state in a new type of quantum material

In some solid materials under specific conditions, mutual Coulomb interactions shape electrons into many-body correlated states, such as Wigner crystals, which are essentially solids made of electrons. So far, the Wigner ...

Phys.org / Strategic tree planting could help Canada become carbon neutral by mid-century

A new study finds that Canada could remove at least five times its annual carbon emissions with strategic planting of more than six million trees along the northern edge of the boreal forest. The paper, "Substantial carbon ...
