California Murders: and Remembering

I hadn't planned on writing about murder and getting a grip this week. Or next. But another multiple murder is international news....

The Dream



He woke, heart racing, breathless, wet with sweat, in the starlit time before dawn. He shuddered when something touched his arm. It was his wife.

"Again?" she asked, rolling her belly onto him. Soon she would bear his first child.

"Again," he gasped. He waited until his breath came more easily. "The same thing. It was awful."

She waited. He would talk soon. Perhaps then he would sleep.

Swatting Fast Flies

We're a lot smarter than flies, which probably helps us swat them.

But the insects are very good at being somewhere else when the flyswatter or newspaper hits whatever they were on.

I've run into a few reasonable speculations. One was that flies are hypersensitive to air movements, and feel an approaching object. That may be part of the answer.

Scientists found another piece to that puzzle recently. "Recently" by my standards, that is. Flies live a whole lot faster than we do. Or, in a fly's eyes, we move in slow motion....

Wanting Truth



I think truth is important, so do many others. Some see truth in ways that doesn't line up with my views.

Sometimes I can respect how they reached their conclusions. But I still think I'm right. Closer to what's true, at any rate.

That doesn't make me one of humanity's paragons of candor and acceptance....

More Disasters

The good news is that folks on the Gulf Coast probably won't be affected by Hurricane Irma. Not directly.

Cleanup and rebuilding there is taking a back seat to news of this weekend's hurricane and Mexico's major earthquake.

I'll be talking about this week's disasters, and how folks deal with them. Also faith, reasonable and otherwise, and a little science....

Labor Day SETI

I nearly missed an interesting development in SETI, the Search for Extraterrestrial Intelligence. Interesting, and as newsworthy as most Stephen Hawking stories, but probably not significant.

Professor Hawking didn't start chatting with aliens over the Labor Day weekend. That would be major news.

But an outfit he's connected with will be listening to FRB 121102. I think it's likely that they'll collect useful data, and that this isn't a prelude to 'first contact.'

Other scientists say they've spotted several planets orbiting Tau Ceti. Two of them may be just inside that star's habitable zone.

Sane Environmentalism

I think being concerned about air quality, recycling, and other environmental issues, makes sense.

But I don't think only being concerned about the environment is a good idea. People matter, too. I don't think it's an either/or thing.

Fukushima, Six Years Later

The Fukushima Daiichi nuclear disaster could have been much worse. But it may have been avoidable.

Meltdowns and non-nuclear explosions at the power plant didn't directly kill anyone.

More than 40 patients who were evacuated from a nearby hospital died later. They had been critically ill. Getting rushed away from a nuclear incident in progress wouldn't have been good for their health.

Three former power company executives now face criminal charges.

The earthquake, tsunami, and meltdowns in 2011 killed nearly 16,000 folks and left many others homeless. Many folks still can't return to their homes. Quakes happen. This one was nobody's fault.

What happened in Fukushima is another matter. I'll be looking at the disaster, what's happened since, and why questioning authority can be a good idea.

Using Vaccines Wisely

Using drones to deliver vaccines seems reasonable for places like Vanuatu.

But vaccines won't help if folks don't know how to use them correctly, or can't.

Others avoid vaccines because they believe warnings from dubious sources.

Oldest Human Fossils?

Humanity's current model may be a whole lot older than we thought.

A team of scientists say that remains found in Morocco are human, Homo sapiens. The scientists also say these folks lived about 300,000 years ago.

If that's confirmed, they were around 100,000 years earlier and about 2,000 miles away from where we thought Homo sapiens showed up.

Other scientists say T. rex may not have been fluffy. It looks like the big dinosaur lost its feathers somewhere along the line.

GSLV, Rocket Lab: Looking Good

India's 'monster rocket,' the GSLV Mark III, successfully put the GSAT-19E satellite in orbit this week.

BBC News called some coverage of ISRO's launch "euphoric."

That's understandable. India is like America in the late 20th century, where spaceflight is involved: and is rapidly catching up. I'm not euphoric, quite, but I see what's happening as very good news for everyone.

Rocket Lab's Electron test launch wasn't entirely successful. But the company thinks they can get the system working, and plan to start commercial launches later this year.

Climate Change, Whirligig Icebergs

Climate change is still in the news. Don't worry, I won't rant about impending doom, or say that Earth's climate isn't changing.

This planet's climate has been changing for several billion years. I'd be astounded if it stopped changing now.

How much we know and understand about our own past, and Earth's, is also changing. I'll be talking about that, and why I'm not upset that we're learning.

I'll also take a look at (real) climate change, why I think we are not doomed, and choices we must make soon. "Soon," in this case, is somewhere in the next millennium or so. My opinion. We really do not want to make these decisions hastily....

Mars: Leaky Red Planet

What we're learning about Mars, and a new type of really small spacecraft, reminded me of earth, air and kilts.

Also pharaohs, Thomas Paine, and Lord Kelvin. By then I was running out of time to write something more tightly-organized.

I figured you might be interested in some of what I have written. On on the other hand, maybe not. So I added links to my ramblings before and after what I said more-or-less about the science news, and figure you can decide what's interesting and what's not.

Pesticides in the Water



I live on Earth, so caring about what happens here makes sense. I've talked about enlightened self-interest, Yeats, Ehrlich, and getting a grip, before. Often, actually. (February 17, 2017; January 20, 2017; September 16, 2016; August 12, 2016)

A news item about scientists finding a particular sort of pesticide in America's drinking water got my attention. So did what they said about it: which made sense.

Whether or not this becomes a hot news item, like the "Flint Water Crisis," depends partly on how badly editors need something to angst over. My opinion.

What happened in Flint, Michigan, was real enough. There's a pretty good Wikipedia page on it. Briefly, Flint's drinking water was okay until the city started drawing from the Flint River instead of Lake Huron and the Detroit River.

Internet Friends, Real People



Near the end of a self-help book, the author wrote that social connections we make with others online aren't "real."

The next sentence said that online communities are "pretend communities." The author explained that they don't "come close to fulfilling the legitimate needs we have."

I understand the point he was making, but don't entirely agree.

It's true that folks I know online won't notice if I left the garage door open, or lend me a few dollars until next payday. In nearly all cases, they can't. They live too far away. Some aren't even on the same continent....

TRAPPIST-1: Water? Life??

TRAPPIST-1's planets may support life: or not. We don't know. Not yet.

We're pretty sure that all seven are rocky worlds, like the Solar System's inner planets.

Three are in the star's habitable zone. The inner two definitely do not have one sort of atmosphere that would make life as we know it impossible.

Even if we don't find life there, we'll learn a great deal while looking.

Face Transplant at Mayo

Andy Sandness wasn't born looking like that. He's lived with the consequences of a "wrong choice" for more than a decade.

Agreeing to get Mayo Clinic's first face transplant won't undo his decision. But now he has a second chance for a normal life.

Pollution: Still Learning

Scientists found PCBs and PBDEs in deep-sea critters, armyworms are on the march in Africa, and Mexico City's air isn't as clean as we'd hoped.

Rational concern seems reasonable....

...Last week I talked about blaming our tools for our mistakes. (February 10, 2017)

This week I'll revisit Lovecraft's "placid island of ignorance,"sort of....

Footprints in Ancient Ash

Scientists are pretty sure that Saccorhytus coronarius is an ancestor of lancets, sea squirts, fish, amphibians, reptiles, dinosaurs, and mammals: including us.

Much more recently, about 3,660,000 years back, five Australopithecus afarensis strolled across volcanic ash. One of them was "astonishingly larger" than any other A. afarensis we know of. Exactly what that means isn't, I think, clear. Not yet.

Gems, Metal, and Earth's Core

The Fire of Australia, a whacking great chunk of opal, isn't particularly interesting from a 'science' viewpoint.

But I'm human, which is probably why anything big and shiny gets my attention: including that rock.

Wrenching myself back on-topic, scientists found a stream of liquid metal flowing at the edge of Earth's core. Studying it may help us learn why Earth's magnetic field flip-flops at apparently-irregular intervals. What we'll learn is beyond me: we didn't know much about geomagnetic reversal when I started school.

We still don't, for that matter. As I keep saying, there is a very great deal left to learn.
