Long-distance earthquake detection
In traditional seismology, researchers studying how the earth moves in the moments before, during, and after an earthquake rely on sensors that cost tens of thousands of dollars to make and install underground. Now researchers have figured out a way to overcome these hurdles by turning parts of a 13,000-mile-long testbed of “dark fiber,” unused fiber-optic cable, owned by the DOE Energy Sciences Network (ESnet), into a highly sensitive seismic activity sensor that could potentially augment the performance of earthquake early warning systems currently being developed in the western United States.

Marine organisms as detectors of enemy undersea activity
Goliath grouper, black sea bass, and snapping shrimp, along with bioluminescent plankton and other microorganisms, are set to be the unlikely additions to protecting U.S. assets. Researchers are developing new types of sensor systems that detect and record the behaviors of these marine organisms and interpret them to identify, characterize, and report on the presence of manned and unmanned underwater vehicles operating in strategic waters. The incorporation of biological signals will extend the range, lifetime, and performance of undersea surveillance technologies in strategic waters.

The opening moments of the Chernobyl disaster: New theory
A brand-new theory of the opening moments during the Chernobyl disaster, the most severe nuclear accident in history, based on additional analysis. The new theory suggests the first of the two explosions reported by eyewitnesses was a nuclear and not a steam explosion, as is currently widely thought.

NRC weakens a critical safety regulation, ignoring Fukushima disaster lessons
The Nuclear Regulatory Commission’s (NRC), in a 3-2 vote, approved a stripped-down version of a rule originally intended to protect U.S. nuclear plants against extreme natural events, such as the massive earthquake and tsunami that triggered meltdowns at the Fukushima Daiichi nuclear plant in Japan in March 2011. The decision will leave U.S. nuclear plants dangerously vulnerable to major floods and earthquakes.

Death in the air: Revisiting the 2001 anthrax mailings and the Amerithrax investigation
Time may have dimmed the memory of the 2001 anthrax attacks and the sense of urgency surrounding the efforts to identify the attacker. The attacks, which involved mailings of five anthrax-laced letters to prominent senators and media outlets, killed five individuals and made seventeen others ill. The anthrax mailings played a crucial role in raising concerns over possible terrorist use of biological agents in attacks against the homeland. As a result of the anthrax scare, Americans’ perceptions of terrorism came to include an existential fear of biological terrorism.

Breeding challenges of land mine-finding rats
Thousands of people – many of them children – are hurt or killed by land mines each year, so finding these devices before they explode is critical. There is a surprising champion of detection: the African giant pouched rat. Native to sub-Saharan Africa, the pouched rats are large – they can grow up to 3 feet long, including the tail – but are still too small to set off the land mines. They have an exceptional sense of smell – they are also used to detect tuberculosis – but scientists know very little about their biology or social structure, and they’re difficult to breed in captivity.

The quiet threat inside ‘internet of things’ devices
As Americans increasingly buy and install smart devices in their homes, all those cheap interconnected devices create new security problems for individuals and society as a whole. The problem is compounded by businesses radically expanding the number of sensors and remote monitors it uses to manage overhead lights in corporate offices and detailed manufacturing processes in factories. Governments, too, are getting into the act – cities, especially, want to use new technologies to improve energy efficiency, reduce traffic congestion and improve water quality. The number of these “internet of things” devices is climbing into the tens of billions. They’re creating an interconnected world with the potential to make people’s lives more enjoyable, productive, secure and efficient. But those very same devices, many of which have no real security protections, are also becoming part of what are called “botnets,” vast networks of tiny computers vulnerable to hijacking by hackers.

U.S. must start from scratch with a new nuclear waste strategy: Experts
The U.S. government has worked for decades and spent tens of billions of dollars in search of a permanent resting place for the nation’s nuclear waste. Some 80,000 tons of highly radioactive spent fuel from commercial nuclear power plants and millions of gallons of high-level nuclear waste from defense programs are stored in pools, dry casks and large tanks at more than seventy-five sites throughout the country. “No single group, institution or governmental organization is incentivized to find a solution,” says one expert.

What should we do with nuclear waste?
The failure to develop a strategy for permanent storage and disposal of this fuel costs Americans billions of dollars a year and jeopardizes the future of nuclear power as a carbon-free source of energy, according to nuclear security expert Rodney C. Ewing. He recommends a new not for profit independent corporation that’s owned and supported by the utilities that operate nuclear power plants. The new organization would deal only with spent fuel from commercial reactors. Defense waste is an entirely different issue and should, at this time, remain the responsibility of the federal government.

Inexpensive super-absorbent material offers solution for ocean oil spills
A super-absorbent material developed by Penn State scientists could dramatically reduce the environmental impact of oil spills on oceans and allow recovered oil to be refined normally. The synthetic material, called i-Petrogel, absorbs more than 40 times its weight in crude oil, and effectively stops the oil from spreading after a spill, according to the researchers.

British spy chief warns Russia against covert activity after nerve-agent attack
The head of Britain’s foreign intelligence service has warned the Kremlin not to underestimate the West following a nerve-agent attack on a retired double agent in England that he attributed to covert Russian activity. Alex Younger, head of the Secret Intelligence Service known as MI6, made the remarks on December 3 in a rare public speech – saying that Russia is in a state of “perpetual confrontation” with the West.

The long view
A Meltdown in Nuclear Security
A commando raid on a nuclear power plant seems the stuff of Hollywood. So why are nuclear security experts so worried? It ranks among the worst-case scenarios for a nuclear power plant: an all-out assault or stealth infiltration by well-trained, heavily armed attackers bent on triggering a nuclear blast, sparking a nuclear meltdown or stealing radioactive material. Under pressure from a cash-strapped nuclear energy industry increasingly eager to slash costs, the commission in a little-noticed vote in October 2018 halved the number of force-on-force exercises conducted at each plant every cycle. Four months later, it announced it would overhaul how the exercises are evaluated to ensure that no plant would ever receive more than the mildest rebuke from regulators – even when the commandos set off a simulated nuclear disaster that, if real, would render vast swaths of the U.S. uninhabitable. Nuclear security experts, consultants, law enforcement veterans and former NRC commissioners are nothing short of alarmed. “You can’t afford to be wrong once,” says one expert.
Can American Values Survive in a Chinese World?
The People’s Republic of China bounds from strength to strength. Every year sees increases in its wealth and power relative to the world. But what do its leaders hope to achieve with their newfound clout? Jonathan D. T. Ward’s book China’s Vision of Victory traces the Chinese desire to shape the future of all mankind (not just the East Asian part of it) to a national myth taught to schoolchildren across China. According to this narrative, China was once the center of the world; China was the mother of invention, the seat of global wealth, and the beacon of civilization. This is China’s natural role in the world order—a role disrupted by the “century of humiliation” between the Opium Wars and World War II, when China suffered at the hands of foreign powers. But now that age of suffering is over. China’s destiny, according to its leaders, is to reclaim its natural perch as the leading force of human civilization. Tanner Greer writes that these global ambitions raises serious questions for the United States – questions which go beyond whether Americans will be willing to live in a world where China is the supreme economic and military power. The “hardest question may be whether we are willing to live in a world where dominant economic and military power is wielded by an insecure regime whose leaders believe that the same authoritarian techniques used to control enemies within their society must be used to surveil, coerce, and corrupt those enemies outside it.”
The U.S. Wants to Bury SC’s Plutonium Stockpile Forever. Its New Home Isn’t Sure It Wants It.
How long will it take for weapons-grade plutonium stockpile, temporarily stored at the South Carolina’s Savanah River nuclear weapons complex, to decay, that it, to have its radioactivity reduced to a level at which it will no longer pose radiation risks or turned into nuclear weapons? About seven billion years, or a little more than double the age of planet Earth. The government’s plutonium plan calls for expanding a nuclear waste burial ground located inside an abandoned salt mine near Carlsbad, New Mexico, which is known as the Waste Isolation Pilot Plant, or WIPP. But New Mexico objects.
Today, Everyone’s a Nuclear Spy
There was a time when tracking nuclear threats was the domain of secret agents, specialists at high-powered government intelligence agencies, and think-tank experts. Not anymore. Amy Zegart writes that today, the world of new nuclear sleuths looks like the Star Wars bar scene. What has empowered these nuclear detectives and made their work possible is the fact that in the last 15-20 years, commercial satellites have become common – and their capabilities, although not at the level of spy satellites, are not too far behind. Open-source amateur nuclear sleuthing comes with risks, but Zegart says that despite these risks, the democratization of nuclear-threat intelligence is likely to be a boon to the cause of nonproliferation.
