The old saying that one bad apple spoils the barrel suggests that an individual behaving badly can have a negative influence on the entire group. The idea now has some fresh scientific backing.
Just like gloves, molecules can have left- and right-handed—or mirror-image—forms. Because the left- and right-handed molecules are still very similar, scientists have had trouble separating them from each other. But a team ...
For the first time, Northwestern University physicists have coaxed a single positron—the antimatter counterpart of an electron—into an exquisitely controlled quantum state.

Marine heat waves are usually seen as destructive events that can disrupt entire ocean ecosystems and trigger massive environmental damage. In 2018 and 2019, an extreme heat wave hit the Bering Sea, causing spring sea ice ...
Insects belong to a broader group of six-legged animals called hexapods. This group also includes other less well-known, small animals, including diplurans or two-pronged bristletails, wingless relatives of insects with two ...
Quantum networks, systems that connect devices and allow them to exchange information encoded in the quantum states of particles, could enable more secure communications. To build these networks, physicists need to devise ...
Sometimes, while people are interacting with each other, their movements and physiological responses can fall into step. Some past studies have linked synchronized bodily responses to cooperation and being attuned to the ...
In most parts of Europe, bees have become less widespread during the last 100 years, according to a new study published in the journal Proceedings of the National Academy of Sciences.
Pulsars are rapidly rotating neutron stars, the extremely dense cores left behind when massive stars explode. Astrophysicists have recently observed a pulsar rotating over 300 times per second that appeared to be slowing ...
