National Security Chip Plant Gets an Upgrade
Sandia National Laboratories has completed phase one of an anticipated three-year upgrade at its plant responsible for making integrated circuits. The upgrade will align Sandia with industry, but the Lab notes that the decision to upgrade was driven by the Lab’s national security mission. Six years of planning ensured the conversion would not affect production of components needed for national defense. Chips produced at Sandia can be found in the nation’s nuclear stockpile.

An Umbrella to Combat Warming
Research examines the possibility of spraying tiny particles into the stratosphere to block the sun a bit and cool the planet. Shielding the Earth with a mist of tiny particles sounds like the stuff of sci-fi movies, but since it was first proposed in the 1950s the idea has gained traction among scientists around the world to shield us not from extraterrestrials, as Hollywood might have it, but from the sun. Known as solar geoengineering, the concept is to send planes into the stratosphere — 6 to 31 miles above the Earth — to spray particles that can reflect sunlight back into space and cool the planet.

Climate Change Could Cause Drought in Wheat-Growing Areas
In a new study, researchers found that unless steps are taken to mitigate climate change, up to 60 percent of current wheat-growing areas worldwide could see simultaneous, severe and prolonged droughts by the end of the century. Wheat is the world’s largest rain-fed crop in terms of harvested area and supplies about 20 percent of all calories consumed by humans.

For Scientific Integrity in Government, Fix Political Appointments Process
The list of scandals featuring senior U.S. officials who subsumed scientific integrity to their political or personal interests numbers 60 entries in a new report from a bipartisan task force that traced practices under the past three presidents. The examples range from downplaying the connections between climate change and carbon emissions under George W. Bush to understating the risks of fracking on drinking water under Barack Obama, and on to retaliation against economists, biologists and climate scientists under Donald Trump. While the vast majority of the incidents listed occurred under the Trump administration, the task force warns that the pattern represents a kind of continuum: that abuses of the past weakened the guardrails of democracy to allow what’s happening today, and that the trend could escalate in future administrations unless Congress takes steps to strengthen safeguards. And at the root of each instance are the individuals who committed the abuses, whether the president or his political appointees.

India-Pakistan Nuclear War Could Kill Millions, Lead to Global Starvation
A nuclear war between India and Pakistan could, over the span of less than a week, kill 50-125 million people—more than the death toll during all six years of World War II, according to new research. The researchers calculated that an India-Pakistan war could inject as much as 80 billion pounds of thick, black smoke into Earth’s atmosphere. That smoke would block sunlight from reaching the ground, driving temperatures around the world down by an average of between 3.5-9 degrees Fahrenheit for several years. Worldwide food shortages would likely come soon after. Today, India and Pakistan each have about 150 nuclear warheads at their disposal, and that number is expected to climb to more than 200 by 2025.

How to Dismantle a Nuclear Bomb: Team Successfully Tests New Method for Verification of Weapons Reduction
How do weapons inspectors verify that a nuclear bomb has been dismantled? An unsettling answer is: They don’t, for the most part. When countries sign arms reduction pacts, they do not typically grant inspectors complete access to their nuclear technologies, for fear of giving away military secrets. Now MIT researchers have successfully tested a new high-tech method that could help inspectors verify the destruction of nuclear weapons. The method uses neutron beams to establish certain facts about the warheads in question — and, crucially, uses an isotopic filter that physically encrypts the information in the measured data.

What’s at Stake in Trump’s War on Huawei: Control of the Global Computer-Chip Industry
Silicon Valley may now be more popularly associated with software companies such as Google and Facebook but it takes its name from the material most used to make semiconductors. Semiconductors – or computer chips – power everything from mobile phones to military systems. The semiconductor industry sits at the center of the modern world. This point is key to appreciating what’s going on in the US government’s battle with Chinese technology giant Huawei.

Containing a Nuclear Accident with Ground-up Minerals
Researchers at Sandia National Laboratories are developing a promising new way to prevent the spread of radioactive contamination and contain the hot molten mass that develops within a nuclear reactor during a catastrophic accident. A team of scientists discovered and patented a process for injecting sand-like minerals into the core of a nuclear reactor during an accident to contain and slow down the progression of a meltdown.

Designing the Coastal City of the Future
Boston is situated along the Gulf of Maine, which is warming faster than 99 percent of the ocean due, in part, to changing sea patterns from melting ice in Greenland and the Arctic Ocean. Coupled with increased heat and precipitation, the rising sea level is threatening the low-lying city, much of which was built on landfill over the past 300 years along a 50-square-mile harbor. To save the 685,000-person city, the local government is calling on architects to help implement one of the most ambitious municipal resiliency plans in the United States: Climate Ready Boston. Launched in 2016 by Mayor Martin J. Walsh, Climate Ready Boston is an initiative to prepare the city for the long-term impacts of climate change.

Arctic Ice Is Melting Faster Than Expected. These Scientists Have a Radical Idea to Save It.
glaciers, polar land, and sea ice are rapidly melting, much faster than many scientists expected, as the Intergovernmental Panel on Climate Change’s (IPCC) report on oceans and the cryosphere released Wednesday reiterated. During a five-day heat wave this summer, Greenland lost more than 60 billion tons of ice, including the biggest loss in a 24-hour period since record-keeping began. Recent projections warn that Arctic summers could be nearly ice-free in 10 to 40 years. These grim warnings have prompted more researchers to apply technological solutions that intervene in the earth’s climate systems to slow the impacts of global warming, also known as “geoengineering.”

China’s Access to Foreign AI Technology
Within the pages of the 2019 Worldwide Threat Report, presented in January of this year by former Director of National Intelligence Dan Coats, is a section titled ‘Emerging and Disruptive Technologies and Threats to Economic Competitiveness’. The assessment summarizes the Intelligence Community’s concerns about AI and Autonomy. In an example of just what the U.S. Government is worried about, the Justice Department recently filed a criminal complaint against a Chinese government official and associates accusing them of trying to get U.S. universities to sponsor visas for people they described as Chinese research scholars, when in fact, says DOJ, the people had been sent to recruit American scientists.

250,000 Cubic Meters of Ice in Danger of Breaking Off Europe's Mont Blanc
Highlighting concerns about global warming, Italian authorities now fear that part of the glacier on Mont Blanc, Europe’s highest mountain, is at risk of collapse. Experts have been monitoring the Planpicieux glacier on Mont Blanc for some time and concerns have been mounting in Italy that a section of the glacier is at risk of collapsing. Mayors of the picturesque ski towns in the area have been taking civil defense measures, including plans for evacuation on a short notice.

Can Going Nuclear Combat Climate Change?
To mitigate climate change, the proportion of low-carbon electricity generation must increase from today’s 36 percent to 85 percent by 2040, the International Energy Agency (IEA) says. IEA and other advocates argue that nuclear power could help fill this gap. However, barriers to a nuclear energy renaissance include safety concerns, aging reactors and high costs for new ones.
