Link Found between Sleep Deprivation and Symptoms of Schizophrenia

Link Found between Sleep Deprivation and Symptoms of Schizophrenia

Scientists at the University of Bonn have discovered that 24 hours of sleep deprivation in humans leads to symptoms of schizophrenia. They published their findings in a July 2, 2014 edition of Journal of Neuroscience (1). Schizophrenia, a psychological disorder that impairs an individual’s ability to differentiate between reality and […]

Sensitization after an Injury Increases Survival

Sensitization after an Injury Increases Survival

Researchers at the University of Texas Medical School released the first piece of concrete evidence that nociceptive sensitization results in an adaptive advantage. Using squid (Doryteuthis pealeii)as their test organism, the scientists demonstrated that both behavioral and neurological changes resulting from noxious stimuli, like a minor injury, increase the likelihood […]

Transmission of Trauma by Sperm RNA

Transmission of Trauma by Sperm RNA

  The effects of trauma can be passed down through generations, resulting in psychiatric disorders like depression in offspring. Researchers have found small non-coding RNAs (sncRNAs), molecules that could be the link between environmental factors, like trauma, and genes (1). Both genetic make-up and environmental factors serve as important contributors […]

First Potentially Habitable Earth-sized Planet Confirmed

Researchers at the Keck Observatory and the Gemini Observatory have discovered a planet that could very much resemble our own. Every star has a zone on its orbit in which water may exist in liquid form. This is deemed the “habitable zone” because it is thought that life cannot thrive […]

Why the Zebra Has Stripes

Why the Zebra Has Stripes

Scientists from University of California, Davis systematically examined the function of zebra stripes. From their analyses, many long-standing, but previously unconfirmed hypotheses were rejected, and it is now believed that zebra stripes serve to avoid biting flies. Prior to this research, there were five main functional hypotheses for the adaptation […]

Bioinformatics Handles Big Data

Bioinformatics Handles Big Data

In the 26th Presidential Faculty Lecture on March 31st, Jason Moore, Third Century Professor and professor of genetics and community and family medicine at the Geisel School of Medicine, gave a lecture on the growing field of bioinformatics and the future of big data. Starting with a brief history lesson, […]

Morning Light Offers Help For Those Wishing to Reduce BMI

Morning Light Offers Help For Those Wishing to Reduce BMI

Specifically, having a majority of the mean light exposure above 500 lux (MLiT500) earlier in the day was associated with having a lower BMI. Note that lux is a unit for illuminance, which qualitatively means brightness. To place this number in perspective, the normal light in a room is roughly […]

Skin color differences inadequate for vitamin D3 compensation in northerners

Skin color differences inadequate for vitamin D3 compensation in northerners

Recent evidence suggests that a non-pigmentation mutation of the epidermal structural protein filaggrin (FLG) better explains how populations in northern latitudes, namely northern Europeans, compensate for lower levels of ultraviolet-B light exposure (1). Scientists from the University of San Francisco compiled loss-of-function FLG mutation prevalence data from various populations and […]

A Semi-Synthetic Organism: The Third DNA Base Pair?

The Romesberg team at The Scripps Research Institute (TSRI) recently created an unnatural DNA base pair that can be incorporated into the genome of E. coli. While in nature the genetic code only contains two DNA base pairs, A-T and C-G, these researchers have made a bacterium that can “stably […]

 
 

Cognition is Rhythmic

Cognition is Rhythmic

Researchers at MIT’s Department of Brain and Cognitive Sciences have evidence that one of the ways the brain stores its massive amount of information is through rhythmic cycles of cell communication. “Everyone knows that you can’t consciously hold two distinct ideas in your head at the same time,” says Earl […]
