Quantum dots at room temp, using lab-designed protein

Nature uses 20 canonical amino acids as building blocks to make proteins, combining their sequences to create complex molecules that perform biological functions. But what happens with the sequences not selected by nature? And what possibilities lie in constructing entirely new sequences to make novel, or de novo, proteins bearing…

Changes in Earth’s orbit may have triggered ancient warming event

Changes in Earth’s orbit that favored hotter conditions may have helped trigger a rapid global warming event 56 million years ago that is considered an analogue for modern climate change, according to an international team of scientists. “The Paleocene-Eocene Thermal Maximum is the closest thing we have in the geologic…

Particles of light may create fluid flow, data-theory comparison suggests

A new computational analysis by theorists at the U.S. Department of Energy’s Brookhaven National Laboratory and Wayne State University supports the idea that photons (a.k.a. particles of light) colliding with heavy ions can create a fluid of “strongly interacting” particles. In a paper just published in Physical Review Letters, they…

Mapping E. coli to overcome antibiotic resistance

Antibiotic resistance, when infection-causing bacteria evolve so they are no longer affected by typical antibiotics, is a global concern. New research at the University of Tokyo has mapped the evolution and process of natural selection of Escherichia coli (E. coli) bacteria in the lab. These maps, called fitness landscapes, help…
