Fish oil prevents onset of schizophrenia: treatment breakthrough

Research starting in the early 90’s has suggested a neurodevelopmental basis for schizophrenia. Other studies suggest a biochemical basis for this abnormal development in schizophrenics related to insufficient fatty acids – fatty acids that contribute to the phospholipids which are the building blocks of neuronal membranes. Growth of axons and dendrites, making new synaptic connections and pruning of old ones, involves the synthesis and breakdown of phospholipids.

Based on findings of reduced fatty acids in people with schizophrenia, researchers have been studying whether giving Long-chane omega-3 polyunsaturated fatty acids (PUFAs) to patients at high risk for developing psychotic disorder would prevent them from developing psychotic disorder.

Infectious cancer in Tasmanian Devils

203426597_bb80b18fca_o.jpg

Around 15 years ago, Tasmanian Devils, those cute little bad-tempered creatures from Down Under, began vanishing as a consequence of a new disease spreading rapidly among the population. Around 1996, a photographer documented severe facial tumors in the Devils in the northeast of Tasmania. By 1999, similar tumors appeared in Devils on the east coast. By 2003 it was clear that the entire population was in decline because of the disease. At first, it was assumed a virus or retrovirus was the cause.

Folic acid supplements in late pregnancy increase risk of asthma

According to CDC statistics, U.S. childhood asthma prevalence more than doubled between 1980 to the mid-1990s and has since plateaued at those historically high levels. Although many triggers and risk factors for asthma have been identified, the reasons behind this increase are not yet understood.

A recent study by University of Adelaide researchers Whitrow, Moore, Rumbold, and Davies may shed some light on the rise in asthma in young children. The study appears to show that the use of folic acid supplements in late pregnancy can lead to increased allergic asthma in children of 3.5 years of age. This human study corroborates earlier studies in mice which indicated that supplementation with folate in pregnancy leads to an allergic asthma phenotype in mice via epigenetic mechanisms (changes in gene expression).

Breakthrough in Down Syndrome – Cognitive dysfunction reversed in mice

Back in the 90’s, a woman named Dixie Lawrence made a splash on the internet by describing how her daughter with Down Syndrome experienced improved growth, health and cognition after starting a regimen of nutritional supplements and piracetam. I recall reading that she noticed that her infant daughter was not actually retarded – at least not yet.

Dixie’s routine for changing diapers always ended with a playful rub of Madison’s stomach. One morning, when Madison was eight months old, a fatigued Dixie said to her, “Well, honey, I’m tired, you’re going to have to rub your stomach yourself.” And Madison did just that.

It hit Dixie like a ton of bricks. She realized that her daughter was not retarded, and that if she wasn’t retarded, she would develop retardation. If this was the case, there had to be something that could slow it down or stop it! In a modest bedroom in rural Louisiana, Dixie Tafoya “looked through the telescope,” and in spite of what everyone “knew,” she saw perfectly round planets. With that insight, she jumped light years ahead of all the “experts.”

In other words, this was a view of Down Syndrome as a developmental problem, where the cognitive deficits increase with age.

Decision support tools, performance support systems and just-in-time learning

Where is the best spot for an educational (or other) intervention?

When there is a workforce performance or knowledge gap to fill, trainers understandably think first of using training to fill it. But is more training really always the best answer? Depending on the skills involved and the characteristics of the audience, process improvement, usability improvement, training or performance support may all be worth considering.

Advanced interfaces, “Smart Ecosystems” and performance support systems in the workplace

“A civilization without instrumentalities? Incredible.” –Forbidden Planet

Although it often seems that computers and communication devices have been growing smaller and smaller with no end in sight, for some purposes, they are still far too intrusive and unintuitive. There are many workplace scenarios where data and communication services would be very beneficial as performance support systems, but the constraints and awkwardness of existing computer interfaces would interfere with the task at hand.

Fortunately, researchers have been working steadily for decades to make computers and communication devices nearly vanish by embedding them into our surroundings and networking them so they can sense the environment and interact with us in a manner that would integrate better with our living and working situations. 

Early research groups developed scenarios to demonstrate the utility of these systems, which included independence support for the elderly, meeting facilitation, augmented driving and enhanced social interaction.

Playing futurologist: small consequences of technological changes

Although some great books [1 and 2] have been written about the huge changes being wrought on society and culture by the digital revolution, it’s just as interesting to speculate about the smaller consequences of the adoption of new technology. Here are some of the ones I’ve noticed, but perhaps you will have your own to add. Please jump in and comment!

Item: Records have given way to CD’s which have given way to digital music streaming and downloads

  • The 70 minute CD-length album format has no real reason to exist anymore. There is no longer a reason to group unrelated tracks together in any particular way. We could even go back to the lengthy psychedelic and progressive rock tracks, if anyone wanted to hear them. Tracks can be sold grouped with hundreds of others or individually.
  • You can’t really give CD’s as wrapped gifts anymore, at least not to people under 60. Who wants that junk cluttering up their house?
