Prairie Strips Save Farms

- Adam Clare


Farmers are on the front line of climate change and to some extent they are accelerating it (deforestation and extensive pesticide use), but smart farmers are fighting climate change and improving their crop yield at the same time. A very successful natural intervention farmers can use are known as praire strips. These are long thin strips of land on a farmer’s field that hosts native species and provide lots of benefits to the surrounding land. They attract insects that help crops, help retain water, and keep the soil healthy in a way that chemical interventions can’t.

Insect and bird populations are more than 2x in prairie strips compared to mono-crop fields – providing vital defense against pests and other ecosystem services

Pollinators increase at around the same rate

Prairie strips turn a veritable green desert into a thriving ecosystem

Start a Small Garden This Spring

- Adam Clare

Anyone can be a gardener and you can too! All you need is a balcony or small plot of land and you can start growing your own food. To some people, the very idea of caring for other living things can be scary – what if all the plants die? Here’s the trick: start small and grow plants that can thrive in your area naturally. No green thumb is needed if you plant local.

An expert gardener has provide ten simple tips for first timers. You can do it!

2. START SMALL

If you are planning how to start a vegetable garden in your backyard then the potential size is likely dictated by what yard space you have. Some people may have grand plans when planning a kitchen garden, though if you are new to vegetable gardening then it may be best to start with a small space.

Starting with focusing on small vegetable garden ideas allows you to learn and get that satisfaction without the risk of getting frustrated by a large vegetable garden that gets weedy and out of control quickly. By starting small it means you can get a feel for how long things take to grow and nurture and the time involved in weeding, watering, fertilizing and harvesting.

It can take up more time than first expected and no-one wants to get disillusioned by turning over a huge space in their backyard to a vegetable garden that they don’t actually have the time in their busy lives to tend. If you do want to transform a large area, then it can be done slowly or sections not cultivated covered with thick cardboard or plastic to smother weeds.

Diagnosis by Dreams

- Adam Clare

What you do while dreaming might be a sign of things to come. This isn’t non-scientific phooey, rather this is real science that can help doctors and patients address neurological issues. There’s been an increase in scientists looking at what people do while dreaming to see if they have Parkinson’s or other neurological difficulties, and by examining dream behaviour it might be possible to provide an earlier diagnosis.

In recent years awareness of RBD and an understanding of how it relates to synucleinopathies have grown. Studying this link is giving researchers ideas for early intervention. These advances contribute to a growing appreciation of the so-called prodromal phase of Parkinson’s and other neurodegenerative disorders—when preliminary signs appear, but a definitive diagnosis has not yet been made. Among the early clues for Parkinson’s, “RBD is special,” says Daniela Berg, a neurologist at the University Hospital Schleswig-Holstein in Germany. “It’s the strongest clinical prodromal marker we have.”

…
Does damage to the brain stem also affect the content of dreams and the actions of dreamers? Sleep researcher Isabelle Arnulf, a professor of neurology at Sorbonne University in Paris, developed a keen interest in the dream-time behaviors of her Parkinson’s patients after noticing an unusual pattern: although these people struggled with movement while awake, their spouses often reported that they had no trouble moving while asleep. One particularly memorable patient, according to Arnulf, had been dreaming of crocodiles in the sleep lab when he lifted a heavy bedside table above his head and loudly shouted, “Crocodile! Crocodile!” to an empty room. When awake, he struggled to lift objects and to speak.

More Trees Means Less Death

Forest

In the cold of winter you might not be thinking of the nice hot summer days as a negative thing. In the winter when temperatures get really low people suffer from hypothermia or worse, whereas in heat they can suffer from heat stroke or worse. When it comes to the heat there’s a nice and simple solution of planting trees.

In urban environments tree coverage can literally save lives by having a minium of 30% of urban space shaded by trees. Not only will the trees reduce heat in their immediate area they will provide cleaners air and a nicer place to be.

We found substantial variation in UHI death rates across European cities. In 2015, Gothenburg in Sweden recorded no premature UHI deaths, while urban heat was responsible for 32 premature deaths per 100,000 people in the Romanian city Cluj-Napoca.

The cities with the highest UHI death rates were in southern and eastern Europe. Most of these cities generally had low tree coverage and recorded the highest UHI effect.

Just 3.3% of Thessaloniki in Greece is covered by trees, resulting in urban temperatures 2.8? higher than the surrounding area. By contrast, 27% of Gothenburg is covered by trees, delivering an UHI effect of just 0.4?.

Overall, southern European cities will benefit most from increasing their tree cover. Our model estimates that Barcelona could reduce its UHI death rate by 60% by meeting the 30% tree coverage target.

Judo Falls for the Elderly

- Adam Clare

When old people fall the results are likely to be far worse than when younger people hit the floor. There’s a long history of technology assistance for elderly individuals who fall from the infamous “I’ve fallen and can’t get up” device to the modern smartwatch with fall detection. As always, the best solution is prevention.

In Quebec an organization has popped up to help teach people how to fall so they don’t injure themselves. Yes, that’s right to prevent falls and help people deal with them is to get them to fall in the first place.

One of the principal lessons is to encourage suppleness and to teach students to not be afraid of falling, says Jean-François Marceau, executive director of Judo Quebec.

As part of the courses, students are taught the basics of how to drop down to — and then get up from — the floor.

“When you go back to that basic thing then you become less afraid of the floor,” said Marceau. “Of course you don’t learn to fall in one lesson and then it’s acquired for life. You have to practise for several weeks … It keeps the reflex on your body and your mind.”
