Schizophrenia and bipolar disorder share genetic roots
A trio of genome-wide studies – collectively the largest to date – has pinpointed a vast array of genetic variation that cumulatively may account for at least one third of the genetic risk for schizophrenia.

Algal blooms are out for blood
The blooming of toxic algae that occurs during the summer conceals a fight for life and death.

Natural-born divers and the molecular traces of evolution
An aquatic lifestyle imposes serious demands for the organism. When the ancestors of present marine mammals initiated their return to the oceans, their physiology had to adapt radically to the new medium.

Site for alcohol’s action in the brain discovered
Alcohol’s inebriating effects are familiar to everyone. But the molecular details of alcohol’s impact on brain activity remain a mystery.

MicroRNAs help control HIV life cycle
Scientists at Burnham Institute for Medical Research (Burnham) have discovered that specific microRNAs (non-coding RNAs that interfere with gene expression) reduce HIV replication and infectivity in human T-cells.

How mitochondria get their membranes bent
Mitochondria are the powerhouses of cells. Underneath their smooth surface they harbour an elaborately folded inner membrane, which holds a multitude of bottleneck like invaginations, which expand into elongated cavities (cristae).

Serotonin makes mice better mothers
A lack of serotonin, commonly known as the ‘happiness hormone’, in the brain slows the growth of mice after birth and is responsible for impaired maternal behaviour later in life.

Toxic molecule may help birds navigate
Researchers at the University of Illinois report that a toxic molecule known to damage cells and cause disease may also play a pivotal role in bird migration.

Biochemical Journal and Clinical Science buck Impact Factor trend
In the 2008 JCR released by Thomson Reuters on Friday 19 June, both the Biochemical Journal and Clinical Science saw their Impact Factors rise.

Scientists capture the first image of memories being made
The ability to learn and to establish new memories is essential to our daily existence and identity; enabling us to navigate through the world.

Discovery of the cell’s water gate may lead to new cancer drugs
The flow of water into and out from the cell may play a crucial role in several types of cancer.

Cells are like robust computational systems, claim researchers
Gene regulatory networks in cell nuclei are similar to cloud computing networks, such as Google or Yahoo!, researchers report today in the online journal Molecular Systems Biology.

Gene evolution process discovered at Leeds
One of the mechanisms governing how our physical features and behavioural traits have evolved over centuries has been discovered by researchers at the University of Leeds.

Deep-frozen microbe may hold clues to extraterrestrial life
A novel bacterium that has been trapped more than three kilometres under glacial ice in Greenland for over 120 000 years, may hold clues as to what life forms might exist on other planets.

Revealed: protein that triggers plant cell division
Cells must be able to divide in ways that create daughter cells that are different from each other, a process called asymmetric division. Scientists know how this happens in animals, but the process in plants has been a mystery.

Tracking down the causes of multiple sclerosis
Despite intensive research, the factors that trigger multiple sclerosis (MS) and influence its progress remain unclear.

Alzheimer's: newly-found peptide offers hope of early test and better treatment
Researchers have detected a peptide in cerebrospinal fluid that can show whether a person is developing Alzheimer's. Measuring the level of this peptide could show up the disease long before any serious damage is done to the brain.

Researchers identify structure of bacteria responsible for travellers’ diarrhoea
Researchers have solved the structure of thin hair-like fibres called ‘pili’ or ‘fimbriae’ on the surface of bacteria that cause travellers’ diarrhoea.
8 June 2009
At long last, how plants make eggs
A long-standing mystery surrounding a fundamental process in plant biology has been solved by a team of scientists at the University of California, Davis.

‘Shock and kill’ research gives new hope for HIV-1 eradication
Latent HIV genes can be ‘smoked out’ of human cells.
4 June 2009
Small molecules mimic natural gene regulators
In the quest for new approaches to treating and preventing disease, one appealing route involves turning genes on or off at will, directly intervening in ailments which result when genes fail to turn on and off as they should.

Urgent action on salt needed
High blood pressure is the leading risk of death in the world. Unfortunately around the world, blood pressure levels are predicted to become even higher, especially in developing countries.

New Knowledge Environment for BJ
The Biochemical Journal has launched a new Knowledge Environment: BJ Metabolism.

MicroRNAs oil the cell's circadian clockwork
Most of our cells possess an internal clock, a group of genes displaying a cyclic expression pattern that reaches a peak once a day.

Scientists develop a new HIV microbicide - and a way to mass produce it
In what could be a major pharmaceutical breakthrough, scientists from St George's, University of London have devised a one-two punch to stop HIV.

Geographic isolation drives the evolution of a hot springs microbe
Sulfolobus islandicus, a microbe that can live in boiling acid, is offering up its secrets to researchers hardy enough to capture it from the volcanic hot springs where it thrives.

New research helps explain how connexin hemichannels are kept closed
Hemichannels are connexin channels that can dock with each other to create a gap junction across two plasma membranes.

Yeast missing sex genes undergo unexpected sexual reproduction
An emerging form of the pathogenic yeast Candida is able to complete a full sexual cycle in a test tube, even though it's missing the genes for reproduction.

New light shed on the enigma of salt intake and hypertension
A high salt intake has been implicated in cardiovascular disease risk for 5000 years. But salt-sensitive hypertension still remains an enigma.
