Senescence also plays a role in embryo development
Researchers propose that senescence appeared in embryos as a switch to turn off cells that are no longer useful — not simply at the end of an organism's life. One of the main mechanisms the body uses to protect itself against cancer is to switch off defective cells by making them senescent which stops a cell from dividing.
Potential drug target in sight for rare genetic diseaseResearchers have discovered the structure of a potential drug target for a MPS I (Mucopolysaccharidosis I), paving the way for an alternative treatment for the condition.
A protein that keeps people — and their skeletons — organized
Most people think that their planners or their iPhones keep them organized, when proteins such as liver kinase b1 (Lkb1) actually have a lot more to do with it.

How do cells know to spread to cover and close a wound — or build an embryo? A team of researchers publishes new insights into how epithelial cells manage to spread out and in the case of a wound, cover an injury.
Deleting any single gene provokes mutations
Johns Hopkins researchers report that the deletion of any single gene in yeast cells puts pressure on the organism’s genome to compensate, leading to a mutation in another gene.
Retrofitted protein opens door for safer gene therapy
A protein engineered by scientists combines proteins active in HIV and Moloney murine leukaemia virus (MLV) replication and may lead to safer, more effective retroviral gene therapy.

Moms may pass stress to offspring
Pregnant women may transmit the damaging effects of stress to their unborn child by way of the bacteria in their vagina and through the placenta, suggest new findings from two animal studies.
Of hurricanes, fungus and Parkinson's disease
Scientists at Rutgers and Emory universities have discovered that an organic compound, often emitted by fungi, causes symptoms of Parkinson's disease in fruit flies and may be linked to Parkinson's and other neurodegenerative diseases in humans.
Antidepressant induces juvenile-like state
Brain development and maturation has long been thought to be a one-way process in which plasticity diminishes with age. The possibility that the adult brain can revert to a younger state and regain plasticity may have to be reconsidered.

Pregnant exercise boosts newborn brain development
As little as 20 minutes 3 times per week is enough to enhance brain activity.
What are you scared of?
What makes mice freeze with fear? A neural switch was discovered using the same neuron-blocking technique, indicating different brain regions process different types of fear. The discovery could have implications for phobias and panic attacks.
mTOR pathway could lead to glioblastoma treatment
Investigators at Johns Hopkins have found a known genetic pathway to be active in many difficult-to-treat pediatric brain tumors called low-grade gliomas, potentially offering a new target for the treatment of these cancers.

Edited RNA + invasive DNA adds individuality
An enzyme that edits RNA may loosen gene control over invasive snippets of DNA and affect how genes are turned on and off. In fruit flies, this newly understood mechanism appears to contribute to differences in individual eye color and life span.
Protein guides production of DNA into RNA
Scientists at the Gladstone Institutes are shedding light on key aspects of transcription, thus coming even closer to understanding the importance of this process in the growth and development of cells—as well as what happens when this process goes awry.
New explanation for infection susceptibility in newborns
Cells that allow helpful bacteria to safely colonize the intestines of newborn infants, also suppress their immune systems to make them more vulnerable to infections.
