Cell powerhouses shape risk of heart disease

(Phys.org) —Genes in mitochondria, the "powerhouses" that turn sugar into energy in human cells, shape each person's risk for heart disease and diabetes, according to a study published recently by researchers at the University ...

Cell nuclei harbor factories that transcribe genes

Our genetic heritage is contained—and protected—in the nucleus of the cells that compose us. Copies of the DNA exit the nucleus to be read and translated into proteins in the cell cytoplasm. The transit between the nucleus ...

Plants let chloroplasts know the time

(Phys.org) —Plant cells communicate information about the time of day to their chloroplasts, the part of their cells that underpins all agricultural productivity on Earth, researchers at the University of Bristol have demonstrated ...

When the cell's two genomes collide

(Phys.org)—Plant and animal cells contain two genomes: one in the nucleus and one in the mitochondria. When mutations occur in each, they can become incompatible, leading to disease. To increase understanding of such ...

Chromosome 'anchors' organize DNA during cell division

For humans to grow and to replace and heal damaged tissues, the body's cells must continually reproduce, a process known as "cell division," by which one cell becomes two, two become four, and so on. A key question of biomedical ...

Mira the supercomputer

Argonne's new supercomputer won't be in full production until 2013, but it represents such a leap forward that just the first two prototype racks already rank among the top 100 fastest computers in the world.
