Daddy Longlegs Won’t Kill You – Having just finished the fall season of outdoor field trips…I enjoyed this article about daddy longlegs/harvestmen which is a frequent find. I’ve picked up some trivia to share next year about them.

Hard of hearing? It’s not your ears, it’s your brain – Evidently, many older people find understanding speech difficult even when their hearing (the ear part) is fine.

Risks of Managing Prairies Exclusively for Plants – Plants are a part of the environment that are sometimes the easiest to see and ‘manage’ ---- but that might not result in a health system. It’s a more complex situation and we often don’t have the depth of understanding to build a sustainable environment that is comparable to the ‘natural’ one that once was there.

Futures Ghosts? Wildlife on the Brink of Extinction – Have you heard of these animals before…and realize they are near extinction? The rusty patched bumble bee has just recently been ‘in the news.’

World’s largest study shows effects of long-term exposure to air pollution and traffic noise on blood pressure and $37 Billion = Health & Climate Costs from Gas Cars in 10 States Every Year – Two articles about impact on health caused by human-caused degradation of our environment.

The Chemistry of Mummification – A post prompted by Halloween. I was a little late in reading it.

Blue Leaf Special – Chloroplasts may be more than just photochemical…they may also be involved in light propagation and light capture….and the interplay between the three functions.

The world’s knowledge is being buried in a salt mine – The Memory of Mankind project is creating a modern version of Sumerian tablets discovered in the desert. The storage area is one of the oldest salt mines in the world – in the Austrian mountains.’ Ceramic microfilm’ Is being created to hold the information in a way that can withstand acid and alkali environments…and solar storm.

The Bug’s Camouflage is Very Impressive – A Lichen Katydid. In our area, the pray mantises are almost as good at blending into their environment!

Can wild seeds save us from food apocalypse? – A little history…a little status report…how and why seed banks are needed.

‘Shadow method’ reveals locomotion of secrets of water striders – We often point out water striders to our elementary school hiking groups. They are always intrigued by the insect that can ‘walk on water.’

In new ozone alert, a warning of harm to plants and to people – Snap beans, milkweed, coneflowers, and other plants turn brown and sickly when ozone occurs at ground level – becoming bio-indicators for this pollutant. While pollution controls have brought down the peak ozone levels, the background levels have been increasing.

Photo of the Week – October 14, 2016 – Fall photos from The Prairie Ecologist.

The amazing cloud cities we could build on Venus – With ‘going to Mars’ being so much in the news recently, it was interesting to read about why Venus might have some advantages over Mars for colonialization.

New satellite image database maps the dynamics of human presence on Earth – Data to support the first release of the ‘Atlas of the Human Planet’ – increasing our understanding of urban areas, population density, and the amount of vegetation in urban areas….and more.

Why do octopuses remind us so much of ourselves? – From National Geographic – so great pictures and article. An octopus has about as many neurons as a cat but two-thirds of them are in their arms!

Pediatricians update digital media recommendation for kids – Hopefully pediatricians bring up this topic with parents. The recommendations seem like common sense to me but maybe they are not intuitive to everyone.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Microplastics – a cause for concern – Lots of questions…only a few answers. It seems like there have been a lot of articles on the topic recently.

Biodiversity has fallen below ‘safe’ levels – We don’t actually know what the ‘safe’ limit is…but do we want to actually find out when there is no recovery? This report is pointing out that 58% of the world’s land has lost more than 10% of its biodiversity. 10% biodiversity loss is the value that was deemed ‘safe’ limit within which ecological function is relatively unaffected.

Early preschool bedtimes cut risk of obesity later on – Another good reason for preschoolers to be regularly tucked into bed by 8 PM!

Electricity generated with water, salt and a 3-atoms-thick membrane –

Splattered Watercolor Paintings Capture the Beautiful Vibrancy of Delicate Flowers – I like just about everything botanical…eye candy too.

Jupiter and Juno – What do we already know about Jupiter’s chemistry? – An infographic from Compound Interest – background for understanding what we already know about Jupiter’s chemistry and what we hope to learn about it from Juno.

From the Earth’s Oceans (images) – From The Scientist. These images reminded me of how different live in the oceans really is than what we experience on land.

Photo of the Week (from The Prairie Ecologist) – Actually – several photos…of little things that thrive in the prairie.

How Type 2 Diabetes Affects the Brain – Two recent studies that have increased our understanding of the cognitive effects of diabetes – refining not only the description of effects but also how the structures of the brain are changed by diabetes.

Yeast emerges as hidden third partner in lichen symbiosis – Wow! This is something I’ll include in my talk with hikers about lichen. They are always fascinated that lichen grows on rocks and tree trunks….that it’s a combination of fungus and algae…and now we can add that there is usually a yeast there too that is often the part producing chemicals to defend the other two organisms in the symbiotic relationship (and sometimes it changes the appears of the lichen too)!
