- Smog Stresses the Skin
Ozone may have damaging effects on a skin enzyme that helps break down environmental pollutants.
- Odds on Serotonin Regulating Gambling Impulses
Rats can learn to play the odds, which is useful because it helps shed light into how the brain regulates gambling behavior.
- Play It Again
A published paper differs from previous theories that suggest that only replay during sleep is important for memory.
- How Nanotubes Suppress the Immune Function?
Inhalation of carbon nanotubes activates cellular signals in the lung, which in turn activate signals in the spleen to suppress the immune function of mice.
- Activating Genes In Live Animals
Tools to precisely regulate gene expression in single cells or whole organisms are reported.
- Nanomaterials in Biological Systems
State-of-the-art understanding of the interactions between nanomaterials and proteins, cells, DNA and other biological surfaces is reviewed.
- Genome Screens Suggest Clues to Multiple Sclerosis Risk
Several common gene variants point to ways in which individuals vary in their susceptibility to the autoimmune disease, multiple sclerosis (MS), according to two studies.
- New Drug Target for Leukaemia
A genetic change in leukaemia cells that is essential to their proliferation, but also makes the cells vulnerable to an existing drug, has been identified.
- Alzheimer's Assemblies Identified
Assemblies of twelve units of the protein amyloid-beta42 are a probable key neurotoxic agent in the development of Alzheimer's disease.
- Can Alzheimer's Disease Be Infectious?
Tangles observed in the brains of Alzheimer's patients induce the formation of similar inclusions when injected into the brains of healthy mice.
- Protein Translation Factor Causes Breast Cancer
Factors that cause a particularly aggressive form of breast cancer are reported online.
- Getting Into the CNS
Clues as to how leukaemia cells can get into the central nervous system (CNS) are reported.
- Copy Number Variation Linked to Neuroblastoma
The presence of a particular DNA copy number variant (CNV) may be associated with the development of an aggressive, often fatal type of childhood cancer of the sympathetic nervous system.
- Sperm DNA Packaging
A paper provides insights into how DNA in sperm is packaged during development, which could reflect the role the paternal genome has in the embryo.
