Scientists discover new "origins of life" chemical reactions
Four billion years ago, the Earth looked very different than it does today, devoid of life and covered by a vast ocean. Over the course of millions of years, in that primordial soup, life emerged. Researchers have long theorized how molecules came to.....»»
Changing the perspective on the origin of enzymatic catalytic power
The enzymes found in living organisms have impressive catalytic power. Thanks to enzymes, the chemical reactions that sustain life happen millions of times faster than they would occur without them. Enzymes speed up reactions by helping to lower the.....»»
Mapping electric fields to help unravel how enzymes work
Every moment in our bodies' cells, countless activities vital to life occur thanks to enzymes. These special proteins act as catalysts by accelerating the pace and improving the selectivity of chemical reactions without undergoing permanent changes t.....»»
A key process in asymmetric cell division preserves the immortality of the germline
During cell division, chromosomes are replicated into two copies—one for each daughter cell. These copies, called sister chromatids, are usually considered identical. In fact, it's the two pairs of sister chromatids that make up the symmetrical X s.....»»
