Researchers identify gene for adapting to changing seasons

Researchers identify gene for adapting to changing seasons
University of Toronto researchers have identified a gene that determines whether the body will adapt to changing seasons. The gene, a micro-RNA called miR-132/212, is part of a mechanism in the brain's central timekeeping system, known as the circadian clock, located in the suprachiasmatic nucleus. This gene has also been previously implicated in mood disorders including depression.

Frogs can help destroy strains of human flu

Frogs can help destroy strains of human flu
Frog mucus is loaded with molecules that kill bacteria and viruses, and researchers are beginning to investigate it as a potential source for new anti-microbial drugs. One of these "host defense peptides," courtesy of a colourful tennis-ball-sized frog species (Hydrophylax bahuvistara) from southern India, can destroy many strains of human flu and protect mice against flu infection, researchers report in the journal Immunity.

Protein could increase effectiveness of vaccines

Protein could increase effectiveness of vaccines
Researchers have discovered a protein they believe would help make vaccinations more effective and provide protection from other diseases such as cancer. The findings, which appear online in Scientific Reports, allows for greater understanding of how vaccine enhancers work and can best be used. Researchers from Boston University School of Medicine (BUSM) purified a protein found on the exterior of bacteria (neisseria meningidis) and used it as an accessary to provide a better vaccination response.

Brain’s navigation more complex than previously thought

Brain’s navigation more complex than previously thought
Just like a driver in a car, the brain needs some basic navigational instruments to get around, and it is not an idle analogy. In fact, scientists have found brain cells that are similar to speedometers, compasses, GPS and even collision warning systems. That simple analogy, however, may belie the more complex way our brains actually map out the world, Stanford researchers report in Neuron.

'Klosneuviruses': next-gen group of giant viruses discovered

'Klosneuviruses': next-gen group of giant viruses discovered
After discovering a novel group of giant viruses with a more complete set of translation machinery genes than any other virus known to date, scientists at the U.S. Department of Energy Joint Genome Institute (DOE JGI), a DOE Office of Science User Facility, believe that this group (dubbed 'Klosneuviruses') significantly increases our understanding of viral evolution.

How sleep deprivation affects memory-making in the brain

How sleep deprivation affects memory-making in the brain
Scientists have known that a lack of sleep can interfere with the ability to learn and make memories. Now, a group of University of Michigan researchers have found how sleep deprivation affects memory-making in the brain. Previously, researchers knew that depriving mice of sleep after the mice performed a task resulted in the mice forgetting aspects of that task.

Study explains varying outcomes for Down Syndrome

Study explains varying outcomes for Down Syndrome
Aneuploidy is a condition in which cells contain an abnormal number of chromosomes, and is known to be the cause of many types of cancer and genetic disorders, including Down Syndrome. The condition is also the leading cause of miscarriage. Disorders caused by aneuploidy are unusual in that the severity of their effects often varies widely from one individual to another.

'Epigenetic clock' improves research on how to extend lifespan

'Epigenetic clock' improves research on how to extend lifespan
Lots of factors can contribute to how fast an organism ages: diet, genetics and environmental interventions can all influence lifespan. But in order to understand how each factor influences aging—and which ones may help slow its progression—researchers need an accurate biomarker, a clock that distinguishes between chronological and biological age. A traditional clock can measure the passage of chronological time and chronological age, but a so-called epigenetic clock can measure biological age.

X-ray study reveals insights into potential drug target

X-ray study reveals insights into potential drug target
  Researchers hope to design a new generation of drugs against an array of deadly diseases. The task, however, is costly, arduous and often ineffective. One of the key challenges is understanding a particular class of proteins adorning cell surfaces, which are the targets of the majority of pharmaceutical drugs.

Area of the brain affected by autism detected

Area of the brain affected by autism detected
  Brain researchers at ETH Zurich and other universities have shown for the first time that a region of the brain associated with empathy only activates very weakly in autistic people. This knowledge could help to develop new therapies for those affected by autism.
