We tach kids how to read so why not teach them to understand how to critique what they read? People tend to be fine with that (although some basic people claim schools shouldn’t teach kids how to question the world around them), so let’s take it the idea of literacy to the 21st century. In Finland they are teaching kindergarten students how to critique and understand arguments made in the news, social media, books, and even their teachers. It turns out that kids are really good at reasoning and will identify “fake news” when they see it.

We soon discovered that children enjoyed playing Sherlock Holmes when fact-checking the claims teachers gave them to verify. After some trial and error, the teachers building the curriculum boiled down complex fact-checking methods into three fundamental questions: Who’s behind the information? What’s the evidence? What do other sources say? These questions are folded in throughout the curriculum, across subjects, and there is continuity from year to year. Young children may learn to tell the difference between a mistake and a hoax, while older students may undertake more advanced projects on elections and threats to democracy.

It would take a lot of time to copy the Finnish approach fully, but a host of experiments in the European Union and beyond suggest that the basic idea can be replicated. The European Commission Expert Group, on which I serve, has explored how education and training initiatives can tackle disinformation through digital literacy in schools throughout Europe. We have produced a report and practical guidelines for teachers and other educators on tackling disinformation, which include activity plans and insights on how to create student-centered approaches. One of the central challenges is that teachers need training, guidance, and support, as well as ways to measure the effectiveness of these lessons.

Multiple Sclerosis Nerve Damage Repaired by Antihistamine

- Adam Clare

Just released research findings from the University of California San Francisco found that nerve damage in people suffering from multiple sclerosis can be repaired by an over the counter antihistamine. MS damages nerves by removing a protective sheath around nerves which typically can’t be fixed, this new research may provide new methods to help those nerves. The antihistamine isn’t 100% effective and won’t cure MS but it does help those dealing with the disease. The more this treatment is understood the more options we have to help those with MS.

Now, researchers from the University of California San Francisco have identified an over-the-counter antihistamine called clemastine that can reverse damage to the myelin sheath and, what’s more, they’ve identified a biomarker that can measure the drug’s effectiveness.

It all hinges on something called the “myelin water fraction” or MWF. Water that is trapped between the layers of myelin that wrap around nerves in the brain can’t move as freely as water that floats between brain cells. The MWF measures the ratio of myelin water to the brain tissue’s total water content and indicates myelin integrity.

The researchers examined 50 patients with MS enrolled in the ReBUILD trial, who were divided into two groups: the first received clemastine for the first three months of the study, and the second received it only in months three to five and were given a placebo to start. Using magnetic resonance imaging (MRI), they measured the MWF in the patients’ corpus callosum, the thick bundle of nerve fibers connecting the brain’s left and right sides that is dense with myelin.

Rural and Urban Areas Have Less Depression

- Adam Clare

Where you live matters in almost every way imaginable, and there’s now more evidence that your location impacts your mental health. We now know that what has been colloquially known is now provably true: rates of depression are higher in suburban communities than elsewhere. Of course, you’re probably thinking that the rural lifestyle is that one that provides the best mental health, but what you probably don’t realize that urban living is also really good for you. So if you’re living in an in between sub-urban and sub-rural area and not feeling great than maybe you should move out the country or in to the city.

We think the relative higher risks of depression found in sprawling, low-rise suburbs may be partly down to long car commutes, less public open space and not high enough resident density to enable many local commercial places where people can gather together, such as shops, cafes and restaurants. But of course, there may be many other factors, too.

This doesn’t mean there aren’t potential benefits to living in the suburbs. Some people may in fact prefer privacy, silence and having their own garden. 

We hope that this study can be used as a basis for urban planning. The study provides no support for the continued expansion of car-dependent, suburban single-family housing areas if planners want to mitigate mental health issues and climate change.

Indoor Plants That Eliminate Carcinogenics

- Adam Clare

Plants are one of the most obvious good things that there can be, and certain plants are excellent at cleaning specific chemicals out of the air. We all know that plants clean the air, but what aspects of air they clean can change from plant to plant. Researchers tried to find which plants are best at cleaning gasoline vapour out of indoor air. Gasoline contains four chemical compounds which are also found in products that use volatile organic compounds (like fire retardent on a couch); so by studying which plants work best they can create an efficient plant based purifier.

The researchers and Ambius designed a Small Live Green Wall (SLGW) using indoor plants known for their phytoremediation abilities. Phytoremediation is the proper term for using plants to clean up contaminated soil, air and water is phytoremediation.

They tested nine SLGW systems, each containing devil’s ivy (Epipremnum aureum), arrowhead vine (Syngonium podophyllum), and spider plant (Chlorophytum comosum). A control was prepared that contained only potting mixture and no plants. The SLGWs were placed in sealed perspex chambers, exposed to volatile organic compounds, and then analyzed using gas chromatography-mass spectrometry.

If you’re looking for a simple list of what plants you can put inside today to start cleaning your indoor air then here you go:

  1. Snake Plant (Sansevieria trifasciata): Snake plants are excellent at removing formaldehyde, benzene, xylene, and toluene from the air. They are known for their ability to thrive in low light conditions and require minimal maintenance.

  2. Peace Lily (Spathiphyllum spp.): Peace lilies are known for their beautiful white flowers and their ability to remove common indoor air pollutants like formaldehyde, benzene, and trichloroethylene. They prefer shady areas and moderate watering.

  3. Golden Pothos (Epipremnum aureum): Golden Pothos, also known as Devil’s Ivy, is a popular choice for indoor spaces. It is effective at removing formaldehyde, benzene, xylene, and carbon monoxide. It is an easy-to-care-for plant that can tolerate low light conditions.

  4. Boston Fern (Nephrolepis exaltata): Boston ferns are known for their high transpiration rates, which helps to humidify the air and remove formaldehyde, xylene, and toluene. They thrive in bright, indirect light and require consistent watering.

  5. Areca Palm (Dypsis lutescens): Areca palms are effective at removing formaldehyde, xylene, and toluene from the air. They are also known for their ability to add moisture to the environment. Areca palms prefer bright, indirect light and regular watering.

  6. Aloe Vera (Aloe barbadensis): Aloe vera plants not only have medicinal properties but also help in purifying the air by removing formaldehyde and benzene. They prefer bright, indirect light and minimal watering.

  7. Dracaena (Dracaena spp.): Dracaena plants come in various species like Dracaena marginata, Dracaena reflexa, and Dracaena fragrans. They can effectively remove formaldehyde, benzene, trichloroethylene, and xylene. Dracaenas thrive in moderate to bright indirect light conditions

Trichloroethylene Exposure Linked to Parkinson’s

- Adam Clare

Finding the source of Parkinson’s disease has been a challenge for many researchers and this year we’ve gotten a lot closer to figuring it out. There are multiple ways that one can get the neurodegenerative disease with no one factor being the deciding one. This year alone researchers have found common enzymes in people suffering from Parkinson’s and are in the process of generating faster detection methods for people so treatment can start earlier. Just this week it was revealed that a widely used chemical called trichloroethylene (TCE) has a strong association with people who have Parkinson’s- so much so that it looks like exposure to the chemical can actually cause the disease.

The report, published today in JAMA Neurology, involved examining the medical records of tens of thousands of Marine Corps and Navy veterans who trained at Marine Corps Base Camp Lejeune in North Carolina from 1975 to 1985. Those exposed there to water heavily contaminated with TCE had a 70% higher risk of developing Parkinson’s disease decades later compared with similar veterans who trained elsewhere. The Camp Lejeune contingent also had higher rates of symptoms such as erectile dysfunction and loss of smell that are early harbingers of Parkinson’s, which causes tremors; problems with moving, speaking, and balance; and in many cases dementia. Swallowing difficulties often lead to death from pneumonia.
