What Trump means when he talks nukes at the State of the Union
President Donald Trump is expected to cover five main topics in his first State of the Union address tonight, including the economy, immigration, infrastructure and trade. The fifth topic, national security, will put the spotlight on North Korea and the erratic, ad hominem nuclear standoff between North Korean leader Kim Jong-un and Trump himself. The tension of this relationship has spilled over to Twitter, where Trump has lobbed insults and threats at Kim over the past year. Trump called Kim "little Rocket Man" and declared the US' "nuclear button" was "much bigger and more powerful" than Kim's. In August, Trump promised "fire and fury" if North Korea didn't stop testing nuclear weapons, and Kim later called Trump a "mentally deranged dotard." Meanwhile, North Korea carried out more than a dozen nuclear tests throughout 2017, including launching intercontinental ballistic missiles theoretically capable of striking the US mainland. Its most recent ICBM test was in November.

Hawaii senator wants feds to handle future nuclear attack warnings
On January 13th, a statewide alert warned Hawaiians about an incoming nuclear attack -- which turned out to be a mistake caused by human error. Whoops! The resulting finger-pointing revealed serious shortcomings about the state government's disaster response, including the governor's difficulty logging in to his Twitter account to tweet out an all-clear. But US senator Brian Schatz of Hawaii doesn't think fixes are enough: He wants to take the responsibility for nuclear warnings away from local and state governments and give it to the feds alone.

Russian hackers target the US nuclear industry
The New York Times and Bloomberg both claim that Russian hackers have been attempting to infiltrate America's nuclear power industry. The infiltrations themselves have been public knowledge since last week, but now fingers are being pointed towards the usual suspects. Unlike Stuxnet, a worm that specifically targeted nuclear facilities, this program was not intended to take down the plants themselves. Instead, malware was used in an attempt to infiltrate the corporate networks of the companies that run the power plants.

South Korea turns its back on coal and nuclear power
South Korea is clearly a tech-savvy country when companies like Samsung and LG dominate, but you almost wouldn't know it by looking at its energy policies. It not only depends heavily on coal and nuclear reactors (70 percent of its power comes from those sources), but gives them tax breaks to keep prices down. However, it's making an about-face now that there's a new president. New leader Moon Jae-in is proposing an energy strategy that would discourage the uses of coal and nuclear in favor of both natural gas and renewable sources like hydro and solar. It would be unusually rapid -- and not without potential problems.

Switzerland votes for an end to nuclear power
Countries like the UK might still embrace nuclear power, but Switzerland is headed in the opposite direction. The country has voted in favor of an energy plan that will eventually eliminate any use of nuclear power, shifting its efforts toward renewable sources like solar and wind. While there's no timetable for the nuclear shutdown, which was chosen through a binding referendum. However, efforts should get underway in January 2018 -- you may hear more details by then.

Watch these declassified nuclear test films on YouTube
There's something both beautiful and unnerving about a mushroom cloud. The United States conducted around 216 atmospheric nuclear tests between 1945 and 1992, many taking place in Nevada and the Pacific Proving Grounds. Now, rare videos of those detonations are declassified and available to the public for the first time.

Study says Fukushima region is safe enough for people to return
Fukushima's ill-fated nuclear power plant may still be so dangerous that it kills robots, but residents are trickling back as officials decide that radiation levels are safe in some areas. But are they safe enough that you'd never have to worry about long-term effects? According to two researchers, the answer is yes. They've published a study indicating that the cesium radiation levels in Date, 37 miles away from the Fukushima plant, have dropped so quickly (60 percent just between 2011 and 2013) that residents shouldn't suffer any harm. In fact, they may be safer than usual. The median lifetime radiation dose (18 millisieverts) should be less than what you typically receive just by living on Earth.

US hopes cyberattacks will stall North Korea's missile program
The US might not have had much success with cyberattacks against North Korea's nuclear program, but that apparently hasn't stopped officials from further efforts... not that they're having much success. The New York Times has learned that then-President Obama ordered escalated cyberwarfare against North Korea in 2014 a bid to thwart its plans for intercontinental ballistic missiles. However, it's not clear that this strategy has worked -- and there may be problems if it does.

Endless nuclear power can be found in the seas
Climate change is such an urgent issue that despite problems with radioactive waste, nuclear power is once again viable until renewable solutions like solar and wind are more widely adopted. The ocean is a good source of uranium fuel, but it exists in such small quantities that extracting it hasn't been economically feasible. However, Stanford researchers have developed a new technique that can capture up to three times more, meaning we might soon get a new source of uranium that could help keep CO2 in check.

US Navy decommissions the first nuclear-powered aircraft carrier
It's the end of an era for the US sea power, in more ways than one: the Navy has decommissioned the USS Enterprise (CVN-65), the world's first nuclear-powered aircraft carrier. The vessel launched in 1961 and is mainly known for playing a pivotal role in several major incidents and conflicts, including the Cuban Missile Crisis, the Vietnam War and the 2003 Iraq War. However, it also served as the quintessential showcase for what nuclear ships could do. Its eight reactors let it run for years at a time, all the while making more room for the aircraft and their fuel.

The US is preparing to modernize its nuclear weapons systems
The United States has not updated its nuclear weapons program in decades, but in February President Barack Obama allocated more than $1 trillion to the modernization of the country's nuclear stockpile. Perhaps he got tired of hearing jokes about servicemen using floppy disks to activate missiles, but regardless of the catalyst, the US is preparing to create a brand new nuclear weapons system that includes connecting its missiles via a secure network. In 2017, 50 men and women on the Air Force Scientific Advisory Board will be tasked with figuring out what could go wrong in this brave new world, Defense One reports.

Half of UK electricity now comes from nuclear and renewables
A record 50 percent of the UK's electricity was generated from renewables and other low carbon energy sources in the third quarter of 2016. That's up from 45.3 percent the year prior, a milestone fuelled by a sizeable increase in wind, solar and nuclear energy. A neat quarter came from renewables, including hydroelectric, while the other 25 percent was sourced from nuclear reactors. According to the UK government, the growth in green energy can be attributed, at least in part, to "improved weather conditions" across the UK, including higher wind speeds, increased rainfall and longer stretches of sunlight (though I don't remember that last one happening).

Japan axes its 'fast' nuclear reactor prototype
Japan's Monju reactor was supposed to be a more efficient alternative to conventional nuclear power. The "fast," sodium-cooled prototype plant would produce more plutonium than it ate up, making it relatively easy to recycle fuel. However, that's not how it worked out. A leak and fire led to a 15-year shutdown starting in 1995, and the reactor has been plagued by failures, mismanagement and political fights ever since. And now, the government has had enough: it's planning to close Monju once and for all. It would be slower and more expensive to fully restart the reactor than to shut it down (the equivalent of $4.6 billion versus $3.2 billion), officials claim, and the focus is on developing more practical fast reactors instead.

Mammoth UK nuclear plant receives final government thumbs-up
Eight years after it was first proposed, the UK government today gave the final go-ahead for Hinkley Point C, a new nuclear power plant to be built in Somerset. The two-reactor site is expected to become operational in 2025, at which point the majority of live nuclear power stations in the UK will be decommissioned, or only a few years away from the same fate. Point C is slated to generate 3,200 megawatts -- roughly 7 percent of the UK's total consumption and well over double the output of any currently operational site. The first new nuclear plant to be built in the UK in decades, it'll also be one of the priciest projects the world has even seen, with conservative estimates putting construction costs alone at £18 billion.

Russia debuts the largest ever nuclear icebreaker
Russian cargo ships understandably have to wade through a lot of ice, and the country plans to deal with that frozen water in style. It recently floated out the Arktika, which it bills as the "largest and most powerful" nuclear-powered icebreaker in the world. At nearly 569 feet long and 112 feet wide, the twin-reactor boat can carve a gigantic path through some of the sea's toughest obstacles -- it can cut through ice roughly 10 feet thick. It can haul about 36,000 short tons, and there's a helicopter to scout for any upcoming floes.

UK's proposed nuclear plant is one of the costliest things on Earth
Nuclear power has been around for decades, but it still isn't cheap... in fact, it may result in one of the most expensive objects on the planet. Cost estimates for the UK's proposed Hinkley Point C reactor have crept up to £24 billion (about $35 billion), making even some of humanity's more ambitious construction projects seem like small potatoes. The Large Hadron Collider cost "just" $5.8 billion to build, the BBC notes. About the only thing that rivals Hinkley on Earth is Chevron's recently completed $54 billion natural gas plant in Australia. If you're not picky, the International Space Station's collective modules top everything at a total of $110 billion.

Stop nuclear devastation at the heart of a never-ending Cold War
One of the most famous works of graffiti on the Berlin Wall is a depiction of former Soviet general secretary Leonid Brezhnev kissing the ex-leader of East Germany, Erich Honecker, full on the mouth. In the painting, called "My God, Help Me to Survive This Deadly Love," Brezhnev's profile commands a majority of the frame, as if he's sucking the life out of Honecker. It's based on a 1979 photo of the two statesmen locked in a fraternal kiss, a common form of greeting among socialist leaders at the time. Fast-forward to 2016, and artist Rafal Fedro of inbetweengames has updated this iconic painting to feature US president Barack Obama and Russian president Vladimir Putin sharing their own fraternal kiss. In the studio's latest project, a spy tactics game called All Walls Must Fall, the new painting represents a wide range of scenarios: heightened tensions between the two countries that were at the heart of the Cold War, fraying international relationships, or the subconscious desire to love our enemies, to name a few interpretations.

Even robots can't survive Fukushima's ground zero
Five years after an earthquake-triggered tsunami hit Japan's Fukushima Daichi nuclear power plant, there's still a tremendous amount of cleanup work left. The Tokyo Electric Power Co. (TEPCO), which runs the plant, has managed to clean out spent fuel rods from one building, but it's failed to reach others that have melted down. The incredibly high radiation levels at the site have even proven too much for five robots that were sent in to find those rods, Reuters reports. Even worse, it takes around two years for TEPCO to design robots suited to individual buildings at Fukushima.

Russia has plans to nuke Earth-bound asteroids, if necessary
From 2012 to 2015, Russia researched ways of deflecting Earth-bound asteroids using nuclear weapons and came up with a best-case scenario, The Telegraph reports. The Central Scientific Research Institute of Machine Building, an arm of Russia's state-run Roscosmos space agency, worked on the asteroid problem with other countries (including the United States) in a program called NEOShield, which was largely funded by the European Commission. Note that "NEO" in this case stands for "Near-Earth Object," not The One you're probably imagining.

Iran shuts down most of its nuclear program
Iran promised to shut down the majority of its nuclear program in return for an end to stiff economic sanctions, and it's making good on its word. International Atomic Energy Agency inspectors have confirmed that Iran is meeting its end of a 2015 deal that will limit its ability to produce nuclear weapons. The terms had it shut down two thirds of its nuclear centrifuges, eliminate 98 percent of its low-enriched uranium supplies, halt construction of a key reactor and curb both its refinement as well as its research for the next 15 years. It's also subject to tighter inspections that theoretically prevent it from restarting weapons development within the next 25 years.
