A better way to count molecules discovered

(PhysOrg.com) -- Researchers at the Swedish medical university Karolinska Institutet have developed a new method for counting molecules. Quantifying the amounts of different kinds of RNA and DNA molecules is a fundamental ...

Mice with fewer insulin-signaling receptors don't live longer

Scientists studying longevity thought it might be good to lack a copy of a gene, called IGF1 receptor, that is important in insulin signaling. Previous studies showed invertebrates that lacked the copy lived longer, even ...

Spatial organization of transcribed eukaryotic genes

The basic process of life, known as transcription, is the process by which the genetic information stored in DNA is copied by specific enzymes called RNA polymerases into RNA molecules. Despite a huge progress in our understanding ...

Research team gives drug dropouts a second chance

(Phys.org) -- A cross-disciplinary team of researchers at the University of Maryland has designed a molecular container that can hold drug molecules and increase their solubility, in one case up to nearly 3000 times. Their ...

A new source of maize hybrid vigor

Steve Moose, an associate professor of maize functional genomics at the University of Illinois and his graduate student Wes Barber think they may have discovered a new source of heterosis, or hybrid vigor, in maize. They ...

How to keep the nucleus clean

Cells are small factories that constantly produce protein and RNA molecules by decoding the genetic information stored in the DNA of their chromosomes. The first phase of this decoding, the transcription process, 'transcribes' ...

A surprising new function for small RNAs in evolution

An international research team in including Christian Schlötterer and Alistair McGregor of the Vetmeduni Vienna has discovered a completely new mechanism by which evolution can change the appearance of an organism. The ...

DNA gridlock: Cells undo glitches to prevent mutations

Roughly six feet of DNA are packed into every human cell, so it is not surprising that our genetic material occasionally folds into odd shapes such as hairpins, crosses and clover leafs. But these structures can block the ...
