Nano-breakthrough: Solving the case of the herringbone crystal
Leading nanoscientists created beautiful, tiled patterns with flat nanocrystals, but they were left with a mystery: Why did some sets of crystals arrange themselves in an alternating, herringbone style? To ...

As climate changes, boreal forests to shift north, relinquish more carbon than expected
It's difficult to imagine how a degree or two of warming will affect a location. Will it rain less? What will happen to the area's vegetation? New Berkeley Lab research offers a way to envision a warmer future. It maps how ...

16 atomic ions simulate a quantum antiferromagnet
(Phys.org) —Frustration crops up throughout nature when conflicting constraints on a physical system compete with one another. The way nature resolves these conflicts often leads to exotic phases of matter ...

Lucky bacteria strike it rich during formation of treatment-resistant colonies
In biology, we often think of natural selection and survival of the fittest. What about survival of the luckiest? Like pioneers in search of a better life, bacteria on a surface wander around and often organize into highly ...

Intriguing state of matter previously predicted in graphene-like materials might not exist after all
Virtually every material undergoes atomic-level ordering when cooled to temperatures approaching absolute zero. Liquid water, for example, is frozen into atomically ordered crystalline ice. However, condensed ...
