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.
