Francis Halzen was awarded the Nobel Prize in Physics on Tuesday for pioneering a telescope, the IceCube Neutrino Observatory, that paved the way for a new kind of astronomy. Scientists used this telescope, embedded deep in the ice at the South Pole, to detect ghostly particles known as neutrinos whizzing in at high energies from the far reaches of the universe.

Ignacio Taboada, a physicist at the Georgia Institute of Technology and a former IceCube spokesperson, said that he and his colleagues had expected Dr. Halzen to win a Nobel Prize for some time.

“He has been relentless in the pursuit and promotion of the field of neutrino astronomy for decades,” Dr. Taboada said.

If you dropped the exact same pulse of food onto two identical bacteria, you'd expect the exact same response. That's not what happened. In a study published in PRX Life in May 2026, researchers at Carnegie Mellon University and Georgia Tech found that E. coli exposed to unstable, feast-and-famine conditions adapted to new food far faster than bacteria pulled from a stable environment, even when the immediate conditions in front of them were identical.

You may think that one cell has no place to keep things such as memories. Scientists, including Josiah Kratz, a postdoctoral fellow in Georgia Tech’s School of Physics, observed tens of thousands of individual E. coli bacteria through a special microfluidic apparatus and found that the cause was ribosomes, the components of the cell responsible for building proteins and determining the growth rate.
