Soft Cell

For over a hundred years scientists have tried to pin down life as it carries on regardless; to formalise its hidden rules using maths, or using increasingly powerful computers to simulate the volatile, complex, seemingly random events in cells, organs and ecosystems. Past efforts focus on smaller parts of the whole – models of signalling inside cells, or processes like cell division. But here scientists bring some of the pieces together, using computer models to simulate a simplified bacterial cell. Pictured after replicating its DNA, the virtual bacterium separates its 'mother' chromosome (green) from the two new 'daughter' chromosomes, partitioned into different areas of the cell by specific proteins, ready for the cell to divide. Simulating such 'simple' life is a step towards models of more complex mammalian cells, in health and disease.

Germ Warfare

The danger posed by bacteria becoming increasingly resistant to antibiotics has been brought to the attention of the G8 nations by the UK’s Chief Medical Officer, Dame Sally Davies. She warns that even routine operations could become risky within 20 years if the world fails to develop a new generation of antibiotics. One potential source is the human body, which makes natural germ-killing substances known as antimicrobial peptides. About 1,700 of these peptides have been detected including dermcidin, produced in sweat to disinfect cuts and grazes. Dermcidin kills bacteria by making holes in their surface – a strategy that is difficult for bugs to evolve defences against. Scientists recently studied how these holes are formed and the computer simulation pictured shows peptide molecules in orange and dark blue, forming a channel into the cell. This hole allows ions to flow uncontrollably across the cell membrane, with fatal results.

Our eyes may be our window to the world, but how do we make sense of the thousands of images that flood our retinas each day? Scientists at the University of California, Berkeley, have found that the brain is wired to put in order all the categories of objects and actions that we see. They have created the first interactive map of how the brain organizes these groupings. The result — achieved through computational models of brain imaging data collected while the subjects watched hours of movie clips — is what researchers call “a continuous semantic space.” Some relationships between categories make sense (humans and animals share the same “semantic neighborhood”) while others (hallways and buckets) are less obvious. The researchers found that different people share a similar semantic layout.
