Glaciers May Offer Safe Sites for Nuclear Waste Storage
New insights into rates of bedrock erosion by glaciers around the world will help to identify better sites for the safe storage of nuclear waste. The findings of a new research overturn earlier research, showing that erosion rates do not increase with the speed of glacier flow as quickly as previously anticipated.

Transportation Beliefs of 20 Years Ago Largely Myths, Today’s Predictions Will Be as Well
As long as humans have been moving, there have been fantastic predictions about how technology will revolutionize transportation. Most of them turn out to be myths. A new study revisits an influential article that called out widely held transportation predictions of 20 years ago as myths, finding it is still highly accurate.

Smaller Detection Device for Nuclear Treaty Verification, Archaeology Digs
Most nuclear data measurements are performed at accelerators large enough to occupy a geologic formation a kilometer wide, like the Los Alamos Neutron Science Center located on a mesa in the desert. But a portable device that can reveal the composition of materials quickly on-site would greatly benefit cases such as in archaeology and nuclear arms treaty verification.

Safe, Effective Shipboard Firefighting
Fire on board! This is a grave danger for any ship, but especially so when a ship is ostensibly safely docked in harbor – where “normal” firefighters are on duty and have to cope with the special challenges on board a ship. The countless types of vessels and their different structures coupled with the unique aspects of firefighting operations on the water present unusual and difficult operating conditions for traditional firefighters and involve many risks.

Terrorists and Technological Innovation
On 9 October 2019, a terrorist motivated by anti-Semitic beliefs descended on a synagogue in Halle, Germany, where people were observing the Yom Kippur holiday. Daveed Gartenstein-Ross, Colin P. Clarke, and Matt Shear write that Baillet’s use of steel, wood and 3-D-printed plastic components to manufacture three weapons is an example of how violent nonstate actors (VNSAs) adopt new technologies. “As new technologies proliferate, there will invariably be individuals trying to figure out how to use these technologies to kill,” they write.

Protecting U.S. Northern Border with the Slash CameraPole
The border between the United States and Canada is the longest in the world. It stretches across remote wilderness for 5,525 miles, from Maine to Alaska, and presents a formidable surveillance challenge. Though the terrain can be treacherous, illegal crossings and smuggling still occur. However, a unique opportunity for detection exists in the form of a cleared stretch of land at the border that is approximately 20-feet wide, 1,349 miles long, and is referred to as the “Slash.”

Forensic Methods for Getting Data from Damaged Mobile Phones
Criminals sometimes damage their mobile phones in an attempt to destroy evidence. They might smash, shoot, submerge or cook their phones, but forensics experts can often retrieve the evidence anyway. Now, researchers at the National Institute of Standards and Technology (NIST) have tested how well these forensic methods work.

Science Helps Improve Eyewitness Testimony
As we move through the world, looking at objects and people, we generally trust that we are accurately perceiving what’s out there. But research has shown that part of what we see sometimes originates in our own minds — that our brains fill in blanks in our vision based on our expectations or past experiences. Now science — and the insights it provides about the pitfalls in our vision and memory — is improving the way eyewitness testimony is taken and used.

It Is Now 100 Seconds to Midnight
The Bulletin of the Atomic Scientists’ Doomsday Clock is now closer to midnight than ever in its history. The Bulletin cites worsening nuclear threat, lack of climate action, and rise of “cyber-enabled disinformation campaigns” in moving the clock hand. December 2020 marks the 75th anniversary of the first edition of the Bulletin of the Atomic Scientists, initially a six-page, black-and-white bulletin and later a magazine, created in anticipation that the atom bomb would be “only the first of many dangerous presents from the Pandora’s Box of modern science.”

Nuclear Waste Recycled for Diamond Battery Power
A team of physicists and chemists hope to recycle radioactive material directly from a former nuclear power plant in Gloucestershire, U.K., to generate ultra-long-lasting power sources.

Researcher Tests “Vaccine” Against Hate
Amid a spike in violent extremism around the world, a communications researcher is experimenting with a novel idea: whether people can be “inoculated” against hate with a little exposure to extremist propaganda, in the same manner vaccines enable human bodies to fight disease.

Edible “Security Tag” Protects Drugs from Counterfeit
Manufacturing prescription drugs with distinct markings, colors, shapes or packaging isn’t enough to protect them from counterfeiting, DEA reports have shown. Researchers are aiming to stump counterfeiters with an edible “security tag” embedded into medicine. To imitate the drug, a counterfeiter would have to uncrack a complicated puzzle of patterns not fully visible to the naked eye.

The Prospects of Climate Engineering
Climate engineering may offer a last-ditch technological solution to catastrophic climate change, but who makes the decisions on which solutions to implement, and who the beneficiaries will be? Once we start fiddling with the Earth’s fundamental processes, where will it end?

Countering Hate Speech by Detecting, Highlighting “Help Speech”
Researchers have developed a system that leverages artificial intelligence to rapidly analyze hundreds of thousands of comments on social media and identify the fraction that defend or sympathize with disenfranchised minorities such as the Rohingya community. Human social media moderators, who couldn’t possibly manually sift through so many comments, would then have the option to highlight this “help speech” in comment sections.

Autonomous Vehicle Technology Vulnerable to Road Object Spoofing and Vanishing Attacks
Researchers have demonstrated the potentially hazardous vulnerabilities associated with the technology called LiDAR, or Light Detection and Ranging, many autonomous vehicles use to navigate streets, roads and highways. The researchers have shown how to use lasers to fool LiDAR into “seeing” objects that are not present and missing those that are – deficiencies that can cause unwarranted and unsafe braking or collisions.
Tantalizing Method to Study Cyberdeterrence
Tantalus is unlike most war games because it is experimental instead of experiential — the immersive game differs by overlapping scientific rigor and quantitative assessment methods with the experimental sciences, and experimental war gaming provides insightful data for real-world cyberattacks.
Prototype Self-Service Screening System Unveiled
TSA and DHS S&T unveiled a prototype checkpoint technology, the self-service screening system, at Harry Reid International Airport (LAS) in Las Vegas, NV. The aim is to provide a near self-sufficient passenger screening process while enabling passengers to directly receive on-person alarm information and allow for the passenger self-resolution of those alarms.

An International Space Station battery fell back to Earth and, luckily, splashed down harmlessly in the Atlantic. Should we have worried? Space debris reenters our atmosphere every week.

Drones have many positive applications, bad actors can use them for nefarious purposes. Two recent field demonstrations brought government, academia, and industry together to evaluate innovative counter-unmanned aircraft systems.
Strengthening the Grid’s ‘Backbone’ with Hydropower
Argonne-led studies investigate how hydropower could help add more clean energy to the grid, how it generates value as grids add more renewable energy, and how liner technology can improve hydropower efficiency.
The Tech Apocalypse Panic is Driven by AI Boosters, Military Tacticians, and Movies
From popular films like a War Games or The Terminator to a U.S. State Department-commissioned report on the security risk of weaponized AI, there has been a tremendous amount of hand wringing and nervousness about how so-called artificial intelligence might end up destroying the world. There is one easy way to avoid a lot of this and prevent a self-inflicted doomsday: don’t give computers the capability to launch devastating weapons.
