Reprogramming the oocyte

(Phys.org)—Among other things, the egg is optimized to process the sperm genome. The cytoplasmic factors that make this possible also give the egg the ability to reprogram the nuclei from other kinds of cells if these nuclei ...

Driving myelination by actin disassembly

(Phys.org)—If a metallurgist wanted to determine how a blade was made they might cut a small cross section, mount, polish, and etch it, and then look at it under a microscope. They could probably tell right away whether ...

Researchers design first artificial ribosome

Researchers at the University of Illinois at Chicago and Northwestern University have engineered a tethered ribosome that works nearly as well as the authentic cellular component, or organelle, that produces all the proteins ...

Toxoplasma parasite's greedy appetite may be its downfall

Toxoplasma gondii is estimated to chronically infect nearly one-third of the world's population, causing the condition Toxoplasmosis. It is most commonly associated with handling cat feaces and is a particular threat to pregnant ...

How human cells can dissolve damaging protein aggregates

Cellular repair systems can dissolve aggregated proteins and now Heidelberg researchers have successfully decoded the fundamental mechanism that is key to dissolving these protein aggregates in human cells. Their in-vitro ...

New simple proteins play active role in cellular function

Yale scientists have developed simple new proteins almost devoid of chemical diversity that still play a surprisingly active and specific role in cellular function, causing cells to act like cancer cells, they report Aug. ...

Why do mitochondria retain their own genome?

It sounds like science fiction to suggest that every cell in the human body is occupied by a tiny genome-equipped organelle, with which we exist in symbiosis. But in actuality, eukaryotic life is dependent on mitochondria, ...

A look at living cells down to individual molecules

EPFL scientists have been able to produce footage of the evolution of living cells at a nanoscale resolution by combining atomic force microscopy and an a super resolution optical imaging system that follows molecules that ...
