AGU News:

Scientists show for the first time that large sand ripples known as megaripples are migrating on Mars, according to a new study. The findings suggest Mars’s dusty surface might be much more active than previously suspected, offering clues about the Red Planet’s poorly understood atmosphere.

Sand dunes and ripples are typical features of deserts on both Earth and Mars. Megaripples are distinguished from smaller ripples by the coarser sand grains that gather

Approximately 80,000 people are killed as a direct result of the blast, and another 35,000 are injured. At least another 60,000 would be dead by the end of the year from the effects of the fallout.

World Futures: Distance Learning And Teaching – Part Three

By ANDY ANDREWS
Los Alamos World Futures Institute

Learning is a process controlled by the learner, at least when the learner is exposed to learning material.

Every day we experience exposure to real learning material through sight, hearing, smell, taste and touch. We might add vestibular and proprioception, to add some big words as the list goes on.

Real learning occurs when we personally experience something and create some code in our brains. If this is real learning, is there artificial learning?

As an argument one can say that learning is the receipt of information and its transformation

Catch Of The Week: Avoiding Scam Calls

By BECKY RUTHERFORD
Los Alamos

Your cell phone rings, someone claiming to be from Verizon account services is on the other end of the line. They are calling to let you know that your account service is going to be discontinued or suspended unless you can update your information right now.

They might request your PIN, the code that secures your account from unauthorized changes. What should you do? Hang up, and immediately block the number. If they call back from a different number, block that, too. This is likely the first step in an elaborate and painful scam known as SIM swapping.
