Planaria deploy an ancient gene expression programme in the course of organ regeneration
Planarian flatworms have great powers of regeration; sliced through the 'waist', they regenerate the missing tail or head; bisected lengthwise, worms duplicate their mirror image.

Unexpected protein partnership has implications for cancer treatment
Scientists have identified two unlikely partners in a type of immune cell called a macrophage that work together in response to cancer drugs to increase inflammation in a way that may alter tumour growth.

Pioneering findings on the dual role of carbon dioxide in photosynthesis
Researchers at Umeå University have found that carbon dioxide, in its ionic form bicarbonate, has a regulating function in the splitting of water in photosynthesis. This means that carbon dioxide has an additional role to being reduced to sugar.

Researchers create roadmap for gene expression
In a new study, scientists have taken the first steps toward creating a roadmap that may help scientists narrow down the genetic cause of numerous diseases. Their work also sheds new light on how heredity and environment can affect gene expression.

Getting to the root of Parkinson’s disease
Working with human neurons and fruit flies, researchers at Johns Hopkins have identified and then shut down a biological process that appears to trigger a particular form of Parkinson’s disease present in a large number of patients.

Researchers develop bacterial ‘FM Radio’
Programming living cells offers the prospect of harnessing sophisticated biological machinery for transformative applications in energy, agriculture, water remediation and medicine.

Kinesin-5 structure opens cancer drug targets
The structure of a key part of the machinery that allows cells to divide has been identified by researchers at the University of California, Davis—opening new possibilities for blocking runaway cell division in cancer.

Antimicrobial from soaps promotes bacteria build-up in human noses
An antimicrobial agent found in common household soaps, shampoos and toothpastes may be finding its way inside human noses where it promotes the colonization of Staphylococcus aureus bacteria and could predispose some people to infection.

Amino acid fingerprints revealed in new study
For a broad spectrum of diseases, proteins can yield far more useful information than may be gleaned from DNA alone - if researchers can manage to unlock the amino acid sequences from which they are composed.

What bank voles can teach us about prion disease transmission and neurodegeneration
When cannibals ate brains of people who died from prion disease, many of them fell ill with the fatal neurodegenerative disease as well. Likewise, when cows were fed protein contaminated with bovine prions, many of them developed mad cow disease.

Researchers identify how zinc regulates a key enzyme involved in cell death
New findings show how zinc, an essential trace element of human metabolism, interacts with the enzyme caspase-3, which is central to apoptosis or cell death.

Possible explanation for human diseases caused by defective ribosomes
Mutations in some of the proteins that make ribosomes cause disorders characterized by bone marrow failure and anaemia early in life, followed by elevated cancer risk in middle age. These disorders are often called ‘ribosomopathies’.

Researchers reveal a new pathway through the sodium pump
A study in The Journal of General Physiology provides new evidence that the ubiquitous sodium pump is more complex — and more versatile — than we thought.

Erasing a genetic mutation
Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation.
