While popular catalysts called zeolites could help turn paper manufacturing waste and other biomass into fuel, the catalyst crumbles after just two days in hot water. And that's a problem because hot water is nearly ubiquitous ...

Using an ultra fast-scanning atomic force microscope, a team of researchers from the University of Basel has filmed "living" nuclear pore complexes at work for the first time. Nuclear pores are molecular machines that control ...

It was a 3D puzzle with over 1000 pieces, with only a rather fuzzy outline as a guide. But scientists at EMBL have now put enough pieces in place to see the big picture. In a study published today in Science, they present ...

(Phys.org)—Two teams of researchers taking different approaches have successfully mapped and diagramed the nuclear pore complex (NPC)—protein complexes that make up the pores in the nuclear envelope that allow or prevent ...
Caltech scientists have produced the most detailed map yet of the massive protein machine that controls access to the DNA-containing heart of the cell.

Long before animals evolved from sponges, and before plants evolved out of algae, there was a pivotal event that allowed complex, multicellular organisms to arise: the development of the nucleus in single-celled organisms. ...

(Phys.org)—If asked to describe the differences between humans and frogs, a child might say that one hops and rib-its while the other walks and talks. If we ask that same child how to build a frog, they will probably need ...
Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have uncovered new clues to how a molecular machine inside the cell acts as a gatekeeper, allowing some molecules to enter ...

A cell does everything it can to protect its nucleus, where precious genetic information is stored. That includes controlling the movement of molecules in and out using gateways called nuclear pore complexes (NPCs).

Nuclear pores in the nuclear membrane do not only control the transport of molecules into and out of the nucleus but also play an important role in gene expression. Researchers at the Max F. Perutz Laboratories (MFPL) of ...
