Gleanings of the Week Ending September 14, 2019

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.

Radio Tracking a Rare Crayfish – Cool Green Science – There are a lot more species of crayfish than I realized…and they have a bigger role in the stream that I assumed.

Mindfulness for middle school students: Focusing awareness on the present moment can enhance academic performance and lower stress levels -- ScienceDaily – I wonder if ‘mindfulness’ is something we need to teach more overtly now than in the past because technology and daily life tends to push us in ‘unmindful’ ways.

Canadian Canola Fields – I looked at this article because the Bugs101 course that I took recently mentioned the canola fields of Canada (for some reason I had never known very much about Canola as a crop). This article provides more history. It has become a cash crop for Canada in recent decades.

There's a Troubling Rise in Colorectal Cancer Among Young Adults | The Scientist Magazine® - Incidence of colon cancer is falling in older people…but becoming more common in people under 50. It has continued to go up over the past decade. In young adults, the cancer is discovered later too…usually stage 3 or 4.

A Northwest Passage Journey Finds Little Ice and Big Changes - Yale E360 – Lots of changes. Grizzly are moving northward…fewer polar bears…salmon far north of where they used to be…lungworm killing muskox…plastic in ice cores.

Researchers Discover New Family of Viruses | The Scientist Magazine® - The new viruses are found in lung biomes of people that had had lung transplants or have periodontal disease….many times the patients are critically ill. But we don’t know yet if the new family of viruses are linked to disease.

Utah's red rock metronome: Seismic readings reveal Castleton Tower's unseen vibrations -- ScienceDaily – On the plus side – it does not appear that climbers of the tower are impacting it…but this work is a baseline and there could be some longer term effects. Wikipedia has some pictures and a short article about Castleton Tower.

Infographic: History of Ancient Hominin Interbreeding | The Scientist Magazine® - Still learning about the hominin tree and how modern humans carry the genetic heritage.

Camera Trap Chronicles: The Pennsylvania Wilds – Cool Green Science – I wonder what I would see coming through my back yard. I know we have deer…and I occasionally see a fox. Maybe racoons. My first though was to put a camera on the bird feeder or the bird bath.

BBC - Future - Is there a worst time of day to get sick? – Circadian rhythms are important to health….and our medical system doesn’t use them to advantage. I remember being concerned when my mother was in the hospital years ago and the lights were very bright day and night. No wonder she had difficulty sleeping!

Gleanings of the Week Ending June 29, 2019

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.

Porcupines | National Geographic – I was disappointed that they didn’t include more pictures of the North American Porcupine. I’ve never seen one in the wild.

BBC - Future - How to build something that lasts 10,000 years – Specifically – this post is about building a clock that will last for 10,000 years…in West Texas!

Researchers uncover indoor pollution hazards -- ScienceDaily – Some surprises: pollutants change with temperature inside the house….and time of day makes a difference. Formaldehyde seems to be particularly prevalent. These studies are scary for existing homes. We need work on mitigations that homeowners can implement…and new construction that reduces the source of pollutants.

Infographic: Immunity Isn't the Body's Only Defense System | The Scientist Magazine® - Symbiotic bacteria, metabolism and pathogen mutation examples overlay the immunity strategy. As we learn more, we realize that the human body is more complex that we realized.

Top 25 Wild Bird Photographs of the Week: Blue – National Geographic Society Newsroom – So many blue birds!

Tortoises rule on Aldabra Atoll – Tortoises making their way through the huts where people bunked! The tortoises sleep with head and legs stretched out…no predators to fear on the inhospitable atoll.

Past climate change pushed birds from the northern hemisphere to the tropics -- ScienceDaily – Thought provoking. I wondered if some of the birds that now migrate from North America to Central or South America for the winter….will not go as far or will shift their range northward.  I suppose it would work if their food sources shifted and the birds followed the food. The synchrony of plants blooming and seeds ripening….of horseshoe crabs laying eggs…all while birds are migrating or getting ready to produce young; it’s not a simple system.

Making STEM Education More Welcoming to Underrepresented Minorities | The Scientist Magazine® - Education doesn’t happen in a vacuum that has well defined boundaries. We must do more than just academic support…I’m glad there is more research and conversation on how to move forward in tangible ways to make STEM education and careers more open to everyone.

An Ancient Asteroid Crater May Be Hiding Off Scotland’s Coast | Smart News | Smithsonian – Some recent work that points to a crater of a asteroid from 1.2 billion years ago.

Three Studies Track People's Microbiomes Through Health and Disease | The Scientist Magazine® - Interesting…but they could just be expensive association studies (a quote from the end of the paper). At some point, maybe the findings will lead to something that benefits the patient.
