Under the microscope, strong-swimming swamp bacteria spontaneously organize into crystals

Insects form swarms, fish school, birds flock together. Likewise, one species of bacteria forms dynamic, living crystals, says new research from Rockefeller University. Biophysicists have revealed that fast-swimming, sulfur-eating ...

Modeling how cells move together could inspire self-healing materials

A paper published yesterday in Nature's Scientific Reports by a team led by physicist Igor Aronson of the U.S. Department of Energy's Argonne National Laboratory modeled the motion of cells moving together. This may help ...

Hackers begone: Measurement-device-independent QKD increases clock rate and transmission distance while reducing failure

(Phys.org)—In the ongoing effort to make communications secure, Quantum Key Distribution (QKD) theoretically provides a solution – but to the delight of increasingly sophisticated hackers, falls short in real-world systems ...

There and back again: Extending optical storage lifetime by retrieving photon echoes from semiconductor spin excitations

(Phys.org) —For all of their differences, classical and quantum communication have at least one thing in common: the importance of being able to store optical information. That being said, optical storage is a complex process ...

Deconstruction of avant-garde cuisine could lead to even more fanciful dishes

One of the most iconic forms of avant-garde cuisine, also known as molecular gastronomy, involves the presentation of flavorful, edible liquids—like cocktails or olive oil—packaged into spheres. Now a team of scientists, ...

Alcohol clouds in space

Yes, there is a giant cloud of alcohol in outer space. It's in a region known as W3(OH), only about 6500 light years away. Unfortunately it is methyl alcohol (commonly known as wood alcohol, though this stuff is not derived ...
