A simple rule drives the evolution of useless complexity

A new study at the University of Chicago has shown that elaborate protein structures accumulate over deep time even when they serve no purpose, because a universal biochemical property and the genetic code force natural selection ...

USF Study Shows First Direct Evidence of Ocean Acidification

(PhysOrg.com) -- Seawater in a vast and deep section of the northeastern Pacific Ocean shows signs of increased acidity brought on by manmade carbon dioxide in the atmosphere -- a phenomenon that carries with it far-reaching ...

Adjusting acidity with impunity

(PhysOrg.com) -- How do individual cells or proteins react to changing pH levels? Researchers at the MESA+ Institute for Nanotechnology at the University of Twente, The Netherlands, have developed a technique for ‘gently’ ...

Novel polymer delivers genetic medicine, allows tracking

Theresa M. Reineke, associate professor of chemistry in the College of Science, and colleagues in her lab at Virginia Tech and at the University of Cincinnati have developed a new molecule that can travel into cells, deliver ...

Novel enzyme could boost sustainable production of aviation fuel

In recent decades, scientists have sought solutions to improve the sustainable production of biofuels from renewable sources. The latest advance in this field was announced at the end of May by Brazilian researchers and could ...

Novel methods of synthesizing quantum dot materials

For quantum dot (QD) materials to perform well in devices such as solar cells, the nanoscale crystals in them need to pack together tightly so that electrons can hop easily from one dot to the next and flow out as current. ...
