Surprising culprits behind cell death from fat and sugar overload
Excess nutrients, such as fat and sugar, don't just pack on the pounds but can push some cells in the body over the brink. Unable to tolerate this "toxic" environment, these cells commit suicide.

ENCODE project: In massive genome analysis new data suggests 'gene' redefinition
Most people understand genes to be specific segments of DNA that determine traits or diseases that are inherited. Textbooks suggest that genes are copied ("transcribed") into RNA molecules, which are then used as templates ...

RNA
Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate. RNA is very similar to DNA, but differs in a few important structural details: in the cell, RNA is usually single-stranded, while DNA is usually double-stranded; RNA nucleotides contain ribose while DNA contains deoxyribose (a type of ribose that lacks one oxygen atom); and RNA has the base uracil rather than thymine that is present in DNA.
RNA is transcribed from DNA by enzymes called RNA polymerases and is generally further processed by other enzymes. RNA is central to the synthesis of proteins. Here, a type of RNA called messenger RNA carries information from DNA to structures called ribosomes. These ribosomes are made from proteins and ribosomal RNAs, which come together to form a molecular machine that can read messenger RNAs and translate the information they carry into proteins. There are many RNAs with other roles – in particular regulating which genes are expressed, but also as the genomes of most viruses.
