MESA, AZ — Mysterious lights hovering above the east Valley have many wondering if we’ve had a close encounter.

“It was pretty bright, it was about straight up over here, and it went straight that way, stopped, and it didn’t seem like it was too far,” said DJ Maier and Kerri Burnett, describing what they saw.

The couple says they spotted the phenomenon outside their Mesa home on Sunday around nine that night.

Exactly why magic mushrooms go blue when cut was something of a chemical puzzle.

Why do magic mushrooms turn blue when they are cut? Chemists have now unravelled this decade-old mystery, in the process revealing that the dark blue pigments at the centre of the mystery are similar to indigo, the dye used to produce blue jeans.

What’s got the body of a piglet and cells from a monkey? This pig-monkey chimera.

The Star Trek Blueprints (or Booklet of General Plans) are a detailed “Complete Set of 12 Authentic Blueprints” (sized 9-by-30 inches) of the USS Constitution (NCC-1700), a ship of the same class as the USS Enterprise (NCC-1701). (The cover claims the blueprints are “of the Fabulous Starship Enterprise”.)

One of the nice things about a road trip is you often get to see something that really surprises you. A recent trip through Texas may have resulted in my second most surprising sighting. There’s a strange tower that looks oddly like a Tesla tower in the middle of rural Texas, right off the main interstate. What is it? Although Google did answer the question — sort of — I’m still not sure how legitimate its stated purpose is.

First Sighting

I was driving between Wimberly and Frisco — two towns that aren’t exactly household names outside of Texas. Near Milford, there’s a very tall structure that looks like a giant mechanical mushroom on top of a grain silo. If the mushroom were inverted or pointing towards the horizon, it would be easy to imagine it was some very odd antenna. This dish, however, is pointed right down its own odd-shaped mast. The top of the thing sure looks like the top of a Van de Graf generator.

A newfound volcano discovered near Minamitorishima Island, Japan, is a mere 3 million years old, which is quite young for the area.

New Zealand Prime Minister Jacinda Ardern has confirmed that many people remain unaccounted for after a volcano erupted on an island off the coast. Police say they don’t expect any more survivors.

A simple experiment, suitable for performing in an undergraduate physics laboratory, illustrates electromagnetic induction through the water entering into a cylindrical rubber tube by detecting the voltage developed across the tube in the direction transverse both to the flow velocity and to the magnetic field. The apparatus is a very simple example of an electromagnetic flowmeter, a device which is commonly used both in industrial and physiological techniques. The phenomenology observed is similar to that of the Hall effect in the absence of an electric current in the direction of motion of the carriers. The experimental results show a dependence on the intensity of the magnetic field and on the carrier velocity, in good agreement with the theory. Discussion of the system, based on classical electromagnetism, indicates that the effect depends only on the flow rate, and is independent both of the velocity profile and of the electrical conductivity of the medium.
