Millie Bobby Brown’s Evolution Throughout the Years

It’s no secret that Millie Bobby Brown is an icon of our time. The young star’s impressive career took root in 2013, and has only continued to gain steam ever since. The award-winning actress got her start when she was only 9 years old, and since then has starred in one of the most talked-about shows of our time and doesn’t seem to be slowing down anytime soon. Millie Bobby Brown jumpstarted her…

New study shows exactly how the manner in which mitochondria divide has remained the same since evolution began — ScienceDaily

Cellular origin is well explained by the “endosymbiotic theory,” which famously states that higher organisms called “eukaryotes” have evolved from more primitive single-celled organisms called “prokaryotes.” This theory also explains that mitochondria — energy-producing factories of the cell — are actually derived from prokaryotic bacteria, as part of a process called “endosymbiosis.” Biologists…

‘Experimental evolution’ analyses can determine the interactions that proteins use to fold into functional three-dimensional shapes — ScienceDaily

“Proteins are the workers in the cell, and it’s important to know their shape,” says Chris Sander, PhD, director of Dana-Farber’s cBio Center in the Department of Data Sciences. Sander and his colleagues have now demonstrated a powerful “experimental evolution” method to discover details of protein shape and function, and the method may find uses across a very broad spectrum of biomedical…

Not so selfish after all — Key role of transposable elements in mammalian evolution — ScienceDaily

The human genome contains 4.5 million copies of transposable elements (TEs), so-called selfish DNA sequences capable of moving around the genome through cut-and-paste or copy-and-paste mechanisms. Accounting for 30-50% of all of the DNA in the average mammalian genome, these TEs have conventionally been viewed as genetic freeloaders, hitchhiking along in the genome without providing any benefit…

Bacterial lifestyle alters the evolution of antibiotic resistance — ScienceDaily

How bacteria live — whether as independent cells or in a communal biofilm — determines how they evolve antibiotic resistance, which could lead to more personalized approaches to antimicrobial therapy and infection control.

University of Pittsburgh School of Medicine researchers repeatedly exposed bacteria to the antibiotic ciprofloxacin to force rapid evolution. As expected, the bacteria…

Study explores the variation and evolution of Prevotella copri, a common human gut microbe — ScienceDaily

The intestinal microbiome is a delicate ecosystem made up of billions and billions of microorganisms, bacteria in particular, that support our immune system, protect us from viruses and pathogens, and help us absorb nutrients and produce energy.

The industrialization process in Western countries had a huge impact on its content. This was confirmed by a study on the bacteria found in the…

Novel virus type may shed light on viral evolution — ScienceDaily

Viruses are non-living creatures, consisting of genetic material encased in a protein coat. Once the virus infects a living organism, it can replicate itself and continue on. But what happens if a virus lacks the proper tools to infect an organism? How can it propagate?

An international collaboration led by scientists at Tokyo University of Agriculture and Technology (TUAT) in Japan has…
