Zinc deficiency linked to activation of Hedgehog signalling pathway
Zinc deficiency - long associated with numerous diseases - can lead to activation of the Hedgehog signalling pathway, a biomolecular pathway that plays essential roles in developing organisms and in diseases, according to new research at Rensselaer Polyte

Shape-shifting molecule tricks viruses into mutating themselves to death
A new spectroscopy method is helping to clarify the poorly understood molecular process by which an anti-HIV drug induces lethal mutations in the virus’s genetic material.

How a bacterial cell recognizes its own DNA
Bacteria have an immune system to fight off invasive viruses called phages. And like any immune system – from single-celled to human – the first challenge of the bacterial immune system is to detect the difference between ‘foreign’ and ‘self.’

Unearthing new antivirals
A team of biologists from San Diego State University has developed a platform for identifying drugs that could prove to be effective against a variety of viral diseases.

Basis established for nitric oxide joining oxygen and carbon dioxide in respiratory cycle
The latest findings regarding nitric oxide have the potential to reshape fundamentally the way we think about the respiratory system – and offer new avenues to save lives.

Microbes help produce serotonin in gut
Although serotonin is well known as a brain neurotransmitter, it is estimated that 90 percent of the body’s serotonin is made in the digestive tract.

Improved understanding of protein complex offers insight into DNA replication initiation
A clearer understanding of the origin recognition complex (ORC) - a protein complex that directs DNA replication - through its crystal structure offers new insight into fundamental mechanisms of DNA replication initiation.


8 April 2015
New study hints at spontaneous appearance of primordial DNA
The self-organization properties of DNA-like molecular fragments four billion years ago may have guided their own growth into repeating chemical chains long enough to act as a basis for primitive life, says a new study.


7 April 2015
Cells exercise suboptimal strategy to survive
New research shows that it’s not always good for cells’ metabolism to work at peak efficiency.


2 April 2015
Common cholesterol drug stimulates the same receptors as marijuana
New research suggests that fenofibrate activates cannabinoid receptors and may become a viable treatment option for relieving pain, stimulating appetite, reducing nausea and preventing depression.


1 April 2015
Protein may improve liver regeneration
Researchers at UC Davis have illuminated an important distinction between mice and humans: how human livers heal.


31 March 2015
How DNA alarm-system works
Research from Lomonosov Moscow State University clarifies how DNA damage signalling works.


30 March 2015
A long-standing mystery in membrane traffic solved
Researchers have discovered that NSF unravels a single SNARE complex using one round ATP turnover by tearing the complex with a single burst, contradicting a previous theory that it unwinds in a progressive manner.
