Top US Marine says young troops should not be blamed for using TikTok

Gen. David Berger, the US Marine Corps commandant, suggested the concerns surrounding a service members' use of questionable Chinese-owned apps like TikTok should be directed against the military's leadership, rather than the individual troops.

Speaking at the Reagan National Defense Forum in Simi Valley, California, on Saturday morning, Berger said the younger generation of troops had a "clearer view" of the technology "than most people give them credit for."

"That said, I'd give us a 'C-minus' or a 'D' in educating the force on the threat of even technology," Berger said. "Because they view it as two pieces of gear, 'I don't see what the big deal is.'"

Russian secret agents were reportedly stationed in villages in the French Alps

US and European intelligence agencies discovered Russian military intelligence members to be working from the French Alps, according to an NBC News report published Thursday. News of the operation was first reported by French newspaper Le Monde.

Up to 15 members of the GRU, the Kremlin's military intelligence agency, had lived in the French Alps, where they established their base for European covert operations, according to the reports. Some of the alleged officers' names were previously published by Bellingcat, an independent investigative group.

Airmen practice getting the A-10 Warthog ready to fight

The skill and agility of airmen from Moody Air Force Base, Georgia, were on full display at MacDill Air Force Base, Florida, Nov. 19-Nov. 22, 2019, during exercise Mobil Tiger.

The asymmetric advantage of US combat troops is greatly increased by the venerable A-10 Thunderbolt II aircraft. Commonly known as the "Warthog," this staple of combat air support depends greatly upon the expertise of airmen who operate and sustain them.

"Mobil Tiger is an agile combat deployment exercise," said Air Force Major Zachary Krueger, an A-10 pilot assigned to the 23rd Wing Exercises and Plans office at Moody AFB. "The intent was to provide close air support and recover to an austere field, using only weapons and fuel we had available ourselves."

5 times to consider putting your savings in a CD for at least a year

Since interest rates are down compared to last year — and likely to remain unchanged or fall even further in 2020 — it's a good time to be strategic about where you save money.

A certificate of deposit (CD) can offer good earning potential without any of the risk of a stock market investment or the variable interest rates of a high-yield savings account.

When you open a CD, you agree to lock your money up for a specific period of time — usually anywhere from three months to five years — in exchange for a fixed annual percentage yield (APY). You typically can't access your cash until the CD's maturity date without incurring a penalty, which makes it a good place to safely grow money that you need at a certain date and not before then. It can also help curb impulse spending.

Record-breaking NASA sun probe could change Earth's electric grid

NASA's record-breaking solar probe has discovered new, mysterious phenomena at the edge of the sun.

Since it launched in August 2018, the Parker Solar Probe has rocketed around the sun three times, getting closer than any spacecraft before it and traveling faster than any other human-made object in history.

On Wednesday, NASA scientists announced the probe's biggest discoveries so far, in four papers published in the journal Nature.

The research revealed never-before-seen activity in the plasma and energy at the edges of the sun's atmosphere, including reversals of the sun's magnetic field and "bursts" in its stream of electrically charged particles, called solar wind.

'Bursty' solar wind bends the sun's magnetic field

This wind surges into space and washes over Earth, so studying its source could help scientists figure out how to protect astronauts and Earth's electric grid from unpredictable, violent solar explosions.

By sending the Parker probe to the sun, NASA is studying this dangerous wind in more detail than scientists could from Earth.

"Imagine that we live halfway down a waterfall, and the water is always flowing past us. It's very turbulent, chaotic, unstructured, and we want to know what is the source of the waterfall up at the top," Stuart Bale, a physicist who leads the team that investigates the probe's solar-wind data, said in a press call. "It's very hard to tell from halfway down."

NASA scientists are seeking answers to two major questions about the sun: What causes solar wind to accelerate as it shoots out into space? And why is the sun's outer layer, called the corona, up to 500 times as hot as its inner layers?

The new data offers some initial clues. For the first time, Parker identified a clear source of a stream of slow, steady wind flowing out from the sun. It came from a hole in the corona — a spot where the gas is cooler and less dense.

Scientists knew that wind coming from the sun's poles moves faster, but this was the first time they detected an origin point for the slow wind coming from its equator.

The Parker probe also detected rogue waves of magnetic energy rushing through the solar wind. As those magnetic waves washed over the spacecraft, the probe detected huge spikes in the speed of the solar wind — sometimes it jumped over 300,000 mph in seconds. Then just as quickly, the rapid winds were gone.

"We see that the solar wind is very bursty," Bale said. "It's bubbly. It's unstable. And this is not how it is near Earth."

The bursts could explain why the corona is so hot.

"We think it tells us, possibly, a path towards understanding how energy is getting from the sun into the atmosphere and heating it," Justin Kasper, another physicist who studied Parker's observations of solar wind, said in the call.

Scientists had never observed these bursts and bubbles before, but they seem to be common; the Parker spacecraft observed about 1,000 of them in 11 days.

The rogue spikes of energy also delivered an additional surprise: The bursts were so strong that they flipped the sun's magnetic field.

The scientists call these events "switchbacks" because in the affected area the sun's magnetic field whips backward so that it's almost pointing directly at the sun.

The switchbacks seem to occur only close to the sun (within Mercury's orbit), so scientists could never have observed them without the Parker probe.

"These are great clues, and now we can go look at the surface of the sun and figure out what's causing those [bursts] and launching them up into space," Kasper said.

Parker confirmed that there's a dust-free zone around the sun

Scientists have long suspected that the sun is surrounded by an area without cosmic dust, the tiny crumbs of planets and asteroids that float through space and fall into stars' orbits. That's because the sun's heat should vaporize any solid dust that gets too close.

For the first time, Parker flew close enough to the sun to provide evidence that such a dust-free zone exists. It observed that the dust did indeed get thinner closer to the sun.

Still, this zone wasn't quite what scientists expected.

"What was a bit of a surprise is that the dust decrease is very smooth," Russell Howard, another astrophysicist working with the probe, said in the call. "We don't see any sudden decreases indicating that some material has evaporated."

That will be another mystery to prod as the spacecraft gets closer to the sun.

6 more years and 21 more flybys

More knowledge about solar wind and the sun's magnetic field could help scientists better protect astronauts and spacecraft from two types of violent space weather: energetic-particle storms and coronal mass ejections.

In energetic-particle storms, events on the sun send out floods of the ions and electrons that make up solar wind. These particles travel almost at the speed of light, which makes them nearly impossible to foresee. They can reach Earth in under half an hour and damage spacecraft electronics. This can be especially dangerous to astronauts traveling far from Earth.

In a coronal mass ejection, the sun sends billions of tons of coronal material hurtling into space. Such an explosion could massively damage Earth's power grids and pipelines.

Over the next six years, Parker is set to approach the sun 21 more times, getting closer and closer. In its final pass, it should fly within 4 million miles of the sun's surface.

During each flyby, the probe will gather more data that could answer physicists' questions about the sun's corona and solar wind.

"As we get closer, we'll be right in the sources of the heat, the sources of the acceleration of particles, and of course those amazing eruptions," Nicola Fox, NASA's director of heliophysics, said in the call. "Even with what we have now, we already know that we will need to adjust the model used to understand the sun."

Kim Jong Un rides a majestic horse and sends Christmas threats, I guess

North Korea has again lobbed a vague year-end threat at the Trump administration, saying the US can expect a "Christmas gift" if talks between US and North Korean officials don't lead to substantive concessions for North Korea.

As the year-end deadline that the hermit kingdom has given the US runs out, North Korea may renege on the only concession it has given President Donald Trump — the promise to abandon nuclear and long-range weapons testing.

In November, the Korean Central News Agency (KCNA), North Korea's state-run news outlet, released a statement saying that time was quickly running out for the US to resume talks that had stalled after Trump's much-touted visit to the demilitarized zone (DMZ) in June. While US diplomats have said that tentative negotiations in Stockholm last month went well, North Korea's latest missive indicates otherwise.

Meet the Navy's 'Swiss army knife'

The rate of machinist's mate has a long and proud history in the United States Navy. Established in 1880 as finisher, the rate changed names a couple of times before being settled as machinist's mate in 1904.

According to the Navy CyberSpace website on enlisted jobs, "Machinist's mates (non-nuclear) operate, maintain, and repair (organizational and intermediate level) ship propulsion machinery, auxiliary equipment, and outside machinery, such as: steering engine, hoisting machinery, food preparation equipment, refrigeration and air conditioning equipment, windlasses, elevators, and laundry equipment; operate and maintain (organizational and intermediate level) marine boilers, pumps, forced draft blowers, and heat exchangers; perform tests, transfers, and inventory of lubricating oils, fuels, and water; maintain records and reports; and generate and stow industrial gases."

With such a wide array of skills and responsibilities, the machinist's mates in George Washington's engineering department prove the value and versatility of the rate to the ship and to the Navy as a whole.
