Of mice, not men
For more than a century, the laboratory mouse (Mus musculus) has stood in for humans in experiments ranging from deciphering disease and brain function to explaining social behaviours and the nature of obesity.

A bird’s-eye view of the protein universe
How exactly did proteins first come to be? Do they all share a single common ancestor? Or did proteins evolve from many different origins?

Chlamydia knock out the body's own cancer defence
By breaking down the cancer-suppressing protein p53, Chlamydia prevents programmed cell death and favours the process of cancer development.

Scientists uncover mechanism that controls the fitness of cells, affecting aging and disease
A novel looping mechanism that involves the end caps of DNA may help explain the aging of cells and how they initiate and transmit disease, according to new research from UT Southwestern Medical Center cell biologists.

Scientists uncover vast numbers of DNA ‘blind spots’ that may hide cancer-causing mistakes
Cancer Research UK scientists have found more than 400 ‘blind spots’ in DNA which could hide cancer-causing gene faults, according to research published today in Cancer Research.

HIV virulence depends on where virus inserts itself in host DNA
The human immunodeficiency virus (HIV) can insert itself at different locations in the DNA of its human host – and this specific integration site determines how quickly the disease progresses.

What algae do in the dark
Photosynthesis enables plants, algae, and select bacteria to transform the energy from sunlight during the daytime into chemical energy and it involves taking in carbon dioxide from the air and releasing oxygen derived from water molecules.

Thousands of never-before-seen human genome variations uncovered
Thousands of never-before-seen genetic variants in the human genome have been uncovered using a new genome sequencing technology. These discoveries close many human genome mapping gaps that have long resisted sequencing.

Researchers take new approach to stop ‘most wanted’ cancer protein
Researchers have found a way to defeat one of the most tantalizing yet elusive target proteins in cancer cells – employing a strategy that turns the protein’s own molecular machinations against it.

Koala study reveals clues about origins of the human genome
Eight percent of your genome derives from retroviruses that inserted themselves into human sex cells millions of years ago.

Cellular extensions with a large effect
Tiny extensions on cells, cilia, play an important role in insulin release, according to a new study, published in Nature Communications.

How cells defend themselves against antibiotics and cytostatic agents
ABC transporters cause diseases such as cystic fibrosis, while on the other hand they are responsible for the immune system recognizing infected cells or cancer cells.

A matter of life and death: cell death proteins key to fighting disease
Melbourne researchers have uncovered key steps involved in programmed cell death, offering new targets for the treatment of diseases including lupus, cancers and neurodegenerative diseases.
