Fat bacteria? Skinny bacteria? From our perspective on high, they all seem to be about the same size. In fact, they are.
Precisely why has been an open question, according to Rice University chemist Anatoly Kolomeisky, who now has a theory.
A primal mechanism in bacteria that keeps them in their personal Goldilocks zones — that is, just right — appears to depend on two random means of regulation, growth and division, that cancel each other out. The same mechanism may give researchers a new perspective on disease, including cancer.
The “minimal model” by Kolomeisky, Rice postdoctoral researcher and lead author Hamid Teimouri and Rupsha Mukherjee, a former research assistant at Rice now at the Indian Institute of Technology Gandhinagar, appears in the American Chemical Society’s Journal of Physical Chemistry Letters.
“Everywhere we see bacteria, they more or less have the same sizes and shapes,” Kolomeisky said. “It’s the
Each year, thousands of elite and amateur runners compete in the London Marathon. Last year, 42,000 people completed the 26.2-mile course that spans across the British capital, with thousands of people lining the streets to lend their support.
The marathon is an opportunity to achieve personal goals and raise millions of dollars for charitable causes.
But running a mass participation event in the era of Coronavirus is impossible and marathons across the globe have been canceled or postponed, much to the disappointment of those who had spent months training and fundraising for their big day in the limelight.
London hopes things will return to normal for the 2021 event but in the meantime, the 40th staging of the event will take place in a secure bubble in St James Park. Just 100 elite athletes will compete in the men’s, women’s and wheelchair races,
