The events of 9/11 shook the world.

Before that day, we could not imagine that someone would be bold and cruel enough to enact such violence. We could not imagine that two iconic 110-story skyscrapers would collapse in the middle of a U.S. city, gouging and crushing other buildings for hundreds of feet in all directions.

We asked ourselves, “How could this possibly happen? How could they collapse?” These are natural questions that express the scope of the loss we felt on that day.

Structural engineers asked these questions, too, but they also asked the contrasting question: How did the World Trade Center towers manage to stand up to the attack at all, even for a short while? The damage was extensive. Commercial aircraft flying at nearly top speed crashed into the buildings, cutting wide swaths through the exterior walls and inflicting extensive interior damage. Shouldn’t that have been enough to cause immediate collapse?

Why Is the Eastern Monarch Butterfly Disappearing? Is There Something We Can Do About It? | SCITECHDAILY

A Spartan-led research team has uncovered an answer — at least for the most recent population decline — with a huge assist from volunteers.

By Michigan State University, July 19, 2021

From article…

Michigan State University ecologists led an international research partnership of professional and volunteer scientists to reveal new insights into what’s driving the already-dwindling population of eastern monarch butterflies even lower.

Between 2004 and 2018, changing climate at the monarch’s spring and summer breeding grounds has had the most significant impact on this declining population.

In fact, the effects of climate change have been nearly seven times more significant than other contributors, such as habitat loss. The team published its report today (July 19, 2021) in the journal Nature Ecology & Evolution.

“What we do is develop models to understand why monarchs are declining and what’s happening to biodiversity in general,” said Erin Zylstra, the study’s lead author. Zylstra is a postdoctoral researcher in the Department of Integrative Biology and the Ecology, Evolution and Behavior Program, both in MSU’s College of Natural Science.

Event Recap: Why Trust a Corporation to Do a Library’s Job? – Internet Archive Blogs

Although people are increasingly turning to Google to search for information, a corporate search engine is not the same as a trusted librarian.

And while libraries are used to buying and preserving books, they are now often unable to buy and own digital materials because of publisher licensing restrictions.

The tension between the interests of business and the public was the focus of a conversation hosted by the Internet Archive and Library Futures on April 28.

Wendy Hanamura moderated the event with guest panelists Joanne McNeil, author of Lurking: How a Person Became a User; Darius Kazemi, an internet artist and cofounder of Feel Train, a creative technology cooperative in Portland, Oregon; and Jennie Rose Halperin, executive director of Library Futures.

A recording of the event is now available.
