Bristol team creates designer ‘barrel’ proteins
Proteins are long linear molecules that fold up to form well-defined 3D shapes. These 3D molecular architectures are essential for biological functions such as the elasticity of skin, the digestion of food, and the transport of oxygen in blood.

Researchers discover new functionality of molecular light switches
Diatoms play an important role in water quality and in the global climate. They generate about one fourth of the oxygen in the Earth’s atmosphere and perform around one-quarter of the global CO2 assimilation.

New insight that ‘mega’ cells control the growth of blood-producing cells
While megakaryocytes are best known for producing platelets that heal wounds, these ‘mega’ cells found in bone marrow also play a critical role in regulating stem cells according to new research from the Stowers Institute for Medical Research.

How mitochondria began
Parasitic bacteria were the first cousins of the mitochondria that power cells in animals and plants – and first acted as energy parasites in those cells before becoming beneficial, according to a new University of Virginia study.

Prostate cancer’s penchant for copper may be a fatal flaw
Prostate cancer tumours scavenge and hoard copper that is an essential element in the body. But such avarice may be a fatal weakness.

Moderate levels of ‘free radicals’ found beneficial to healing wounds
Long assumed to be destructive to tissues and cells, ‘free radicals’ generated by the cell’s mitochondria—the energy producing structures in the cell—are actually beneficial to healing wounds.

Atomic map reveals clues to how cholesterol is made
In spite of its dangerous reputation, cholesterol is in fact an essential component of human cells. Manufactured by the cells themselves, it serves to stiffen the cell’s membrane, helping to shape the cell and protect it.

Hormone loss could be involved in colon cancer
Some cancers, like breast and prostate cancer, are driven by hormones such as oestrogen and testosterone, but to date, there are none that are driven by the lack of a hormone.

Conspicuous tRNA lookalikes riddle the human genome
Transfer RNAs (tRNAs) are ancient workhorse molecules and part of the cellular process that creates the proteins, critical building blocks of life that keep a cell running smoothly.
