The Death of Arecibo

Apparently, the radio telescope at Arecibo is no more. According to This item on Phys.org the radio telescope has completely collapsed.

“The telescope’s 900-ton receiver platform and the Gregorian dome—a structure as tall as a four-story building that houses secondary reflectors—fell onto the northern portion of the vast reflector dish more than 400 feet below.

The U.S. National Science Foundation had earlier announced that it would close the radio telescope. An auxiliary cable snapped in August, causing a 100-foot gash on the 1,000-foot-wide (305-meter-wide) dish and damaged the receiver platform that hung above it. Then a main cable broke in early November.

The collapse stunned many scientists who had relied on what was until recently the largest radio telescope in the world.”

This has been a long time coming according to this story from 2017 . Nonetheless, I still find it incredibly sad.

Bacteria Made Of Star Stuff

One of the best at explaining science was Carl Sagan. One recurring theme in Sagan’s works can be seen in the quote below:

And we who embody the local eyes and ears and thoughts and feelings of the cosmos we’ve begun, at last, to wonder about our origins. Star stuff, contemplating the stars organized collections of 10 billion-billion-billion atoms contemplating the evolution of matter tracing that long path by which it arrived at consciousness here on the planet Earth and perhaps, throughout the cosmos.

Interesting Science In The News

Some interesting news items that caught my eye.

First, the American Association for the Advancement of Science had a session based on Wilton Krogman’s The Scars of Human Evolution. Krogman, for those unfamiliar with him, was a pioneer in the Field of Forensice Anthropology. He also did some interesting research on primates. You can find more about the symposium here and here. Here is a quote that sums up the session from Eureka Alert:

But applying Darwinian evolutionary theory to the human condition offers a window to why humans suffer from physical ailments that no other animals do, said Latimer, who is on the faculty in the Department of Orthodontics at Case Western Reserve.

Evolving from four-footed walking has created issues from flat feet and bunions to slipped discs, hernias and fallen pelvic floors. And as bizarre as it sounds, rising from four to two feet resulted in reshaping the face and head, which is why humans suffers with such dental problems as wisdom teeth with no room to grow.

Also at the AAAS was a presentation by Nina Jablonski, which sounded fascinating. From Phys.Org:

“We can make a visual impact and present a completely different impression than we can with regular, undecorated skin,” said Jablonski, who reports on her research today (Feb. 16) at the annual meeting of the American Association for the Advancement of Science in Boston. Over the millennia, people turned their skin into canvases of self-expression in different ways, including permanent methods, such as tattooing and branding, as well as temporary ones, including cosmetics and body painting, according to the researcher.

And of course, giving Carl Zimmer yet another book idea.

Einsteinian Relativity At A Personal Scale

This is really cool!:

Scientists have known for decades that time passes faster at higher elevations — a curious aspect of Einstein’s theories of relativity that previously has been measured by comparing clocks on the earth’s surface and a high-flying rocket.

Now, physicists at the National Institute of Standards and Technology (NIST) have measured this effect at a more down-to-earth scale of 33 centimeters, or about 1 foot, demonstrating, for instance, that you age faster when you stand a couple of steps higher on a staircase.

Described in the Sept. 24 issue of Science, the difference is much too small for humans to perceive directly — adding up to approximately 90 billionths of a second over a 79-year lifetime — but may provide practical applications in geophysics and other fields.

ScienceBlogs Jumps The Shark

Pepsi has a blog. What’s next? HuffPo Woo meistering?

Update 1: Okay, I have to admit that Badger3k makes a good point:

If SciBlogs can host Nesbitt without losing credibility, what is a corporate “blog” going to do to it?
