Why did dozens of U.S. Embassy workers in Cuba hear loud sounds and suffer neurological symptoms in 2016? There’s a new, Cold War-era microwave explanation for the mystery.
There’s a monster out there. It’s far away, buried deep in the past. But scientists can see it. And thanks to a new international imaging project, they’ve begun to understand it, too.
We are not living in the first universe. There were other universes, in other eons, before ours, a group of physicists has said. Like ours, these universes were full of black holes. And we can detect traces of those long-dead black holes in the cosmic microwave background (CMB) — the radioactive remnant of our universe’s violent birth.
There’s a sort of radio wave that bangs its way around Earth, knocking around electrons in the plasma fields of loose ions surrounding our planet and sending strange tones to radio detectors. It’s called a “whistler.” And now, scientists have observed bursts like this in more detail than ever before.
Venomous black widow spiders now range farther north than scientists expected, into an area including the most-inhabited parts of Canada. And there’s good reason to suggest that warming temperatures are driving the fatal biters north.
If you’ve ever stood in the totality of a solar eclipse, you’ve seen something astonishing: the full width of the moon’s dark shadow blocking out the sun, perfectly encircled by the dim, wispy rays of the sun’s corona. And if you’ve also stood outside during a lunar eclipse, you might know that the effect is somewhat less dramatic. As Earth’s shadow falls on the moon, it quickly swallows the smaller orbiting rock. The effect of the moon glowing bloody red with Earth’s refracted twilight is beautiful, but the effect doesn’t fully convey the scale of the astronomical phenomenon at work in the same in-your-face way as happens during a solar eclipse. The moon, much smaller than Earth’s shadow, never shows the whole thing on its surface.
Telling time precisely is important; it gets you up in the morning and coordinates everything from air travel to the GPS system. And if you do it well enough, you can even use it to navigate outer space.
Australian parks and wildlife rangers captured a monster of a crocodile Monday (July 9), according to The Sydney Morning Herald. The beast was 15 feet 5 inches long (4.7 meters) and weighed a whopping 1,300 lbs. (600 kilograms).
Scientists in China found a fossil from a giant panda that lived 22,000 years ago. Until they excavated the fossil, reassembled it and analyzed its mitochondrial DNA, biologists had no idea this panda lineage even existed.
Government intelligence agencies have a plan to build computers that store information inside DNA and other organic molecules.
