Hooked on Phononics: Spider Silk Sound and Heat

Steph has another fascinating post, this time discussing newly discovered properties of spider silk. There are beautiful photos of spider webs, too, but not any close-up photos of spiders themselves for those of you who prefer not to view magnified arachnids. Check it out here:    http://wordwomanpartialellipsisofthesun.blogspot.com/2016/07/hooked-on-phononics-spider-silk-sound.html

Amazing coral photos

Steph has posted some amazing photos of corals, along with a post explaining more about them. Check it out!  https://wordwomanpartialellipsisofthesun.blogspot.com/2016/07/bum-in-ocean-in-situ-microscopy-polyps.html

How to Let Go and Love

Last week, I had the opportunity to see Josh Fox’s new documentary, How to Let Go of the World and Love All the Things Climate Can’t Change.

The film takes up where his prior films, Gasland and Gasland 2, left us. Josh’s home in Pennsylvania is saved from fracking when it is banned in the Delaware River watershed. There is rejoicing and dancing – until Josh realizes that a beloved hemlock tree is dying due to a climate-change-related pest, leading to further investigation and travel to see what can be done about it.

The first part of the film reviews a lot of the science of climate change. Well, it is review for me because I have been dealing with issues of fracking, greenhouse gas emissions, and climate change for years now, but may be new information for some viewers. It’s pretty grim, but, just when you are thinking that there isn’t much hope, Josh and his trusty banjo begin travelling the world to show us what people in diverse locations are doing to fight or cope with climate change.

In locations as diverse as Ecuador, China, Zambia, and the islands of the Pacific, Josh visits with communities who band together to care for each other and the planet, standing up to governments and corporations that are doing harm. They use lots of tools – storytelling, investigation, photography, dancing, and canoes among them – to share their love for each other and their home/land, showing us what is really important and lasting.

I will warn anyone who is motion sensitive that Josh uses a handheld camera, which can make some of the video a bit shaky. There are also some drone shots that might affect you. I did have to close my eyes a few times…

How to Let Go and Love has been making the rounds of theater festivals and is on a 100 city tour with Josh conducting Q&A after the film. Schedule information is available from the link above.

It will make its television debut on HBO on Monday, June 27, at 9 PM EDT/PDT. It will also be released later in the year on DVD.

I hope that many people will see this important film.

Earth Day

Another in the string of catch-up posts from this spring…

Earth Day was remarkable for us here in New York State for two reasons this year.

First, the vast majority of the countries of the world signed the Paris climate agreement that day at United Nations headquarters in New York City. Of course, this was a remarkable event for the whole world and we all hope that we finally have the political will to follow through on what the science tells us we must do to avert the most catastrophic consequences of global warming while assisting people everywhere to adapt to the effects that are unavoidable and already underway.

Second, just days before a final deadline, the New York State Department of Environmental Conservation rejected the water quality certificate application that would have permitted the construction of the Constitution methane pipeline.

Those of us in the environmental community have been battling against the further expansion of fossil fuel infrastructure as part of the fight against global warming. Building pipelines for fossil fuels is akin to building whaling ships as whale oil was being displaced by other lighting sources. It doesn’t make sense to prop up a dying technology.

Unfortunately, the decision in New York came too late to save forests in a 22-mile swath of Pennsylvania, where some land was taken by eminent domain and cleared despite the owners’ objection and the fact that the whole project did not have all the permits needed to move forward. We were especially heartbroken for the Holleran family, who lost the majority of their producing sugar maples.

The pipeline company is trying to challenge the DEC’s decision in court. I sincerely hope that the court upholds the DEC’s action to protect our environment and health.

Mount Saint Helens

Re-blogging this post: http://wordwomanpartialellipsisofthesun.blogspot.com/2016/05/may-18-1980-where-were-you-when-mt-st.html  from blogger friend Steph on the anniversary of the eruption of Mount Saint Helens in the western United States.  Great explanations and photos to remind us of the incredible power of geology.

SoCS: watching eggs

On the news this week, there have been several features about eggs.

Specifically, a pair of bald eagle eggs in a nest in the National Arboretum in Washington, DC.

One of them has hatched and the eaglet has enjoyed its first meal. The second is expected to hatch over the weekend.

There is a camera for people to watch a live feed of the nest:  http://www.eagles.org/dceaglecam/

The bald eagle is the national bird of the United States. It was almost killed by DDT, which bioaccumulated in the adult birds and caused its eggs to be so fragile that they could not withstand the weight of the parent when they were being incubated in the nest.

Since the banning of DDT, the population has slowly recovered. Locally, from our area in the Northeast US, we do sometimes spot bald eagles, which would have been incredibly rare twenty or thirty years ago.

Will the second egg hatch? Will both eaglets survive? We can keep a lookout via the camera and find out.

Warm February

This article on the warmest February on record does a good job of explaining how much of the warmth was attributable to El Niño and how much to climate change. Hint:  It’s mostly climate change.

As the scientific evidence mounts, we need more articles like this one to explain to people the gravity of the situation and spur them to action.

Please read and share!

 

SoCS: yet again with the deflated footballs

Hold onto your hats, but there has been more in the news on the topic of Tom Brady, the New England Patriots, and deflated footballs.

Despite not being a big follower of American football – or even what the rest of the world calls football and the US calls soccer – I have written about this topic a number of times. (here and here and here and here and here)

The story was back in the news this week because a seventh grader who lives near Boston won a prize at a science fair by showing with science that the footballs would have dropped about 2 psi due to the field conditions of the game.

Weirdly, he shares a last name with the football commissioner who wanted to sanction Brady, even though there is no proof that he or anyone actually deflated the footballs.

And, yes, this does have to do with things like the ideal gas law that I and others posted about months ago.

Will the National Football League finally acknowledge science and admit they were wrong in their report?

Probably not…

The strength of honeycombs

Time to share another post from Stephanie, who loves science and words and fabulous photos!

This post features the strength of honeycombs, hexagons, and Fibonacci sequences with gorgeous photos of very tiny organisms:
