IoTCustom Circuits to Make IoT Systems 14,000 Times Harder to Crack than Current Tech
The “internet of things” (IoT) allows devices — kitchen appliances, security systems, wearable technologies and many other applications — to communicate with each other through networks. With the world on the verge of adopting them by the billions, the best possible security is paramount. Engineers have one-upped their own technique to increase security for the “internet of things.” In truth, their upping is far greater than one.

Hardware securityMixed-Signal Hardware Security Thwarts Powerful Electromagnetic Attacks
Security of embedded devices is essential in today’s internet-connected world. Security is typically guaranteed mathematically using a small secret key to encrypt the private messages. When these computationally secure encryption algorithms are implemented on a physical hardware, they leak critical side-channel information in the form of power consumption or electromagnetic radiation. Now, researchers have developed technology to kill the problem at the source itself – tackling physical-layer vulnerabilities with physical-layer solutions.

Protective gearWWI Helmets Protect Against Shock Waves as Well as or Better than Modern Designs
Biomedical engineers have demonstrated that, despite significant advancements in protection from ballistics and blunt impacts, modern military helmets are no better at protecting the brain from shock waves created by nearby blasts than their First World War counterparts. And one model in particular, the French Adrian helmet, actually performed better than modern designs in protecting from overhead blasts.

Planetary securityHow to Deflect an Asteroid
MIT researchers have devised a framework for deciding which type of mission would be most successful in deflecting an incoming asteroid. Their decision method takes into account an asteroid’s mass and momentum, its proximity to a gravitational keyhole, and the amount of warning time that scientists have of an impending collision — all of which have degrees of uncertainty, which the researchers also factor in to identify the most successful mission for a given asteroid.

Software securityTool Identifies Source of Errors Caused by Software Updates
We’ve all shared the frustration — software updates that are intended to make our applications run faster inadvertently end up doing just the opposite. These bugs, dubbed in the computer science field as performance regressions, are time-consuming to fix since locating software errors normally requires substantial human intervention. Researchers and computer scientists have designed a tool to identify the source of errors caused by software updates.

Planetary securityAliens May Be Sending Us Probing Messages Every 16 Days
Is there intelligent life out there in the universe? If so, have these intelligent aliens seen us? Have they been trying to find out more about us? New research says they may have been. A just-published scientific paper presents details of blasts of radio waves sent every 16 days from a nearby massive spiral galaxy. Are these radio waves, aimed in the direction of Earth, generated by aliens? Note that the spiral galaxy in question is 500 million light years distant: Even if the fast radio bursts (FRBs) detected were generated by an intelligent civilization, that civilization may no longer exist.

ArgumentThe Next Deadly Pathogen Could Come from a Rogue Scientist. Here’s How We Can Prevent That.
In the past few years, something new has become possible in biology: cheaply “printing” DNA for insertion into a cell. Kelsey Piper writes in Vox that this means a scientist who needs a particular DNA sequence to, say, create new bacteria for research can now order that DNA sequence from a lab. “But what if I asked them to print for me the genetic code of the influenza that caused the 1918 flu that killed millions of people? What if I sent them the instructions for a new disease that I have reason to believe is dangerous? What if I was doing legitimate research, but my lab didn’t adhere to modern safety standards?”

ForensicsForensic Proteomics: Going Beyond DNA Profiling
A new book details an emerging forensic method that could become as widespread and trustworthy as DNA profiling. The method is called mass-spectrometry-based proteomics, which examines the proteins that make up many parts of living things. These proteins exist in unique combinations in everything from blood cells and clothing fibers to certain types of medicine and the diseases they fight. Because proteomics analyzes these proteins directly, forensic proteomics can fill in when DNA is missing, ambiguous, or was never present to begin with.

China syndromeThe Silent Threat of the Coronavirus: America’s Dependence on Chinese Pharmaceuticals
As the new coronavirus, called 2019-nCoV, spreads rapidly around the globe, the international community is scrambling to keep up. In the midst of all of this, a potential crisis simmers in the shadows: The global dependence on China for the production of pharmaceuticals and medical equipment. Today, about 80 percent of pharmaceuticals sold in the U.S. are produced in China. This number, while concerning, hides an even greater problem: China is the largest and sometimes only global supplier for the active ingredient of some vital medications. The U.S. must develop a response plan for the inevitable shortages in the near-term and take necessary actions to reclaim control of our medical supply chain. Continuing to overlook this long-known vulnerability will only lead to catastrophe.

TransportationTransportation 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.

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.

FirefightingSafe, 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.

The long view
Perspective: AIRussia’s AI Quest is State-Driven — Even More than China’s. Can It Work?
The Russian government, more than Western governments and more than China’s, is working hard to position itself as a facilitator and promoter of innovation in artificial intelligence. Vladimir Putin said that the technology will lead whoever masters it to global advantage. Samuel Bendett writes that “Those who doubt that this uniquely state-heavy approach can succeed would do well to remember that today’s internet and mobile telecommunications grew out of Pentagon-funded research, that the Soviet Union led the Space Race for a decade, and that U.S. astronauts currently ascend to orbit atop Russian rockets.”
Perspective: Climate threatsTechnologies to Manage Climate Change Already Exist – but U.K. Needs to Scale Up Efforts Urgently
In the U.K., climate change is being tackled by taking baby steps. Andreas Busch writes that this is unfortunate, because “The world already has effective engineering solutions to manage climate change and to limit global temperatures from rising above 1.5°C – a target set by the Intergovernmental Panel on Climate Change (IPCC). But there is a desperate lack of conviction from politicians and society to address the climate emergency.”
Perspective: Quantum computingA Quantum Computing Future Is Unlikely, Due to Random Hardware Errors
Earlier this fall Google announced that it had demonstrated “quantum supremacy” – that is, that it performed a specific quantum computation far faster than the best classical computers could achieve. IBM promptly criticized the claim, saying that its own classical supercomputer could perform the computation at nearly the same speed with far greater fidelity. “So how can you make sense of what is going on?” Subhash Kak, a professor of Electrical and Computer Engineering, asks. “As someone who has worked on quantum computing for many years, I believe that due to the inevitability of random errors in the hardware, useful quantum computers are unlikely to ever be built.”
Argument: China syndromeThe Chinese Threat to U.S. Research Institutions Is Real
The Chinese government is pursuing a comprehensive, well-organized, and well-funded strategy to exploit the open and collaborative research environment in the United States to advance their economic and military expansion at our expense. Josh Rogin writes that for too long, U.S. research institutions have been asleep to Beijing’s efforts.
PerspectiveArtificial Intelligence: China “Uses Taiwan for Target Practice” as It Perfects Cyber-Warfare Techniques
China has already deployed its expertise in artificial intelligence to make China into a surveillance state, power its economy, and develop its military. Phil Sherwell writes that now Taiwan’s cybersecurity chiefs have identified signs that Beijing is using AI to interfere in an overseas election for the first time. It is “a laboratory for China for adaptation and improvement on political warfare instruments which can then be unleashed against other targeted democratic societies,” Michael Cole, editor of the Taiwan Sentinel, said
