Mass seal deaths in Russia's Lake Baikal

Around 130 dead seals have washed up on the shores of Russia's Lake Baikal, authorities said Tuesday, as they launched a probe into the latest problem to hit the world's deepest lake.

Physicists propose test of quantum gravity using current technology

Physicists have proposed a way to test quantum gravity that, in principle, could be performed by a laser-based, table-top experiment using currently available technology. Although a theory of quantum gravity would overcome ...

A step closer to understanding quantum mechanics: Physicists develop a new quantum simulation protocol

For most everyday experiences, such as riding a bicycle, using a lift or catching a ball, classical (Newtonian) mechanics is perfectly accurate.

Filling the early universe with knots can explain why the world is three-dimensional

The next time you come across a knotted jumble of rope or wire or yarn, ponder this: The natural tendency for things to tangle may help explain the three-dimensional nature of the universe and how it formed.

New insights from OCO-2

High-resolution satellite data from NASA's Orbiting Carbon Observatory-2 are revealing the subtle ways that carbon links everything on Earth - the ocean, land, atmosphere, terrestrial ecosystems and human activities. Scientists ...

Engineers take laser pulses into new dimensions

When you bang on a simple drumhead, it will most certainly make a noise, but you probably wouldn't call that noise a musical note.

The super-Earth that came home for dinner

It might be lingering bashfully on the icy outer edges of our solar system, hiding in the dark, but subtly pulling strings behind the scenes: stretching out the orbits of distant bodies, perhaps even tilting the entire solar ...

Researchers observe dynamical quantum phase transitions in an interacting many-body system

A team of researchers from several institutions in Germany and Austria has developed a means for directly observing dynamical quantum phase transitions in an interacting many-body system. In their paper published in the journal ...
