Another step toward synthetic cells

Building functional synthetic cells from the bottom-up is an ongoing effort of scientists around the globe. Their use in studying cellular mechanisms in a highly controlled and pre-defined setting creates great value for ...

Islands in yeast membrane revealed by extreme microscopy

University of Groningen microbiologists have visualized tiny islands in the cell membrane of baker's yeast. These membrane compartments appear to store transport proteins before use. The scientists observed that these proteins ...

How microbes take out the trash

(PhysOrg.com) -- The molecular machinery bacteria use to rid themselves of toxic substances including antimicrobial drugs has been studied in detail by a UA-led team of researchers. A better understanding of these mechanisms ...

How some tissues can 'breathe' without oxygen

Humans need oxygen molecules for a process called cellular respiration, which takes place in our cells' mitochondria. Through a series of reactions called the electron transport chain, electrons are passed along in a sort ...

Biologists shed light on how cells move resources

Florida State University researchers have new insight into the tiny packages that cells use to move molecules, a structure that is key to cellular metabolism, drug delivery and more.

US officials at odds over cellphone use on planes (Update)

It looks like the U.S. government is more conflicted about cellphones on planes than most American travelers. Even as one federal agency considers allowing the calls, another now wants to make sure that doesn't happen.

New technology solves mystery of respiration in Tetrahymena

Tetrahymena, a tiny single celled-organism, turns out to be hiding a surprising secret: it's doing respiration—using oxygen to generate cellular energy—differently from other organisms such as plants, animals or yeasts. ...
