Quantum dots at room temp, using lab-designed protein
Quantum dots are normally made in industrial settings with high temperatures and toxic, expensive solvents — a process that is neither economical nor environmentally friendly. But researchers have now pulled off the process at the bench using water as…
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. Researchers found the shape of Earth’s orbit, or eccentricity, and the wobble in its rotation, or precession, favored hot…
Particles of light may create fluid flow, data-theory comparison suggests
A new computational analysis 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 new paper, they show that calculations describing such a system match up with…
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 has mapped the evolution and process of natural selection of Escherichia coli (E. coli) bacteria in t…
