Vitamin B12 deficiency: Tracking the genetic causes
Vitamin B12 is essential to human health. However, some people have inherited conditions that leave them unable to process vitamin B12. As a result they are prone to serious health problems, including developmental delay, psychosis, stroke and dementia. An international research team recently discovered a new genetic disease related to vitamin B12 deficiency by identifying a gene that is vital to the transport of vitamin into the cells of the body. This discovery will help doctors better diagnose this rare genetic disorder and open the door to new treatments. The findings are published in the journal Nature Genetics.
Targeted oxidation-blocker prevents secondary damage after traumatic brain injury

Lesson in sleep learning: Associations formed in brains of sleeping volunteers remained intact when subjects were awake
Is sleep learning possible? A new Weizmann Institute study appearing today in Nature Neuroscience has found that if certain odors are presented after tones during sleep, people will start sniffing when they hear the tones alone â€" even when no odor is present â€" both during sleep and, later, when awake. In other words, people can learn new information while they sleep, and this can unconsciously modify their waking behavior.
Scientists identify new gene that influences survival in amyotrophic lateral sclerosis
A team of scientists, including faculty at the University of Massachusetts Medical School (UMMS), have discovered a gene that influences survival time in amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease). The study, published today in Nature Medicine, describes how the loss of activity of a receptor called EphA4 substantially extends the lifespan of people with the disease. When coupled with a UMMS study published last month in Nature identifying a new ALS gene (profilin-1) that also works in conjunction with EphA4, these findings point to a new molecular pathway in neurons that is directly related to ALS susceptibility and severity.

New insights to the function of molecular chaperones
(Phys.org)â€"Heidelberg molecular biologists have gained new insights into the function of so-called molecular chaperones in protein synthesis. The team headed by Dr. Günter Kramer and Prof. Dr. Bernd Bukau of the DKFZ-ZMBH Alliance, a research association between Heidelberg University's Center for Molecular Biology (ZMBH) and the German Cancer Research Center (DKFZ), was able to demonstrate how a molecular chaperone in bacterial cells can influence the formation of the three-dimensional structure of new proteins.
Controlling gene expression: How chromatin remodelers block a histone pass
Two opposing teams battle it out to regulate gene expression on the DNA playing field. One, the activators, keeps DNA open to enzymes that transcribe DNA into RNA. Their repressor opponents antagonize that effort by twisting DNA into an inaccessible coil around histone proteins, an amalgam called chromatin, effectively blocking access to DNA by enzymes that elongate an RNA strand.
Compound boosts effect of vaccines against HIV and flu
Oxford University scientists have discovered a compound that greatly boosts the effect of vaccines against viruses like flu, HIV and herpes in mice.
