Building Standards Give Us False Hope. There's No Such Thing as a Fireproof House
Bushfires have killed 33 people and destroyed nearly 3,000 houses across Australia so far this fire season. Canberra is under threat right now. It isn’t only houses. Significant commercial buildings have been destroyed, among them Kangaroo Island’s iconic Southern Ocean Lodge. In New South Wales alone, 140 schools have been hit. Many require extensive work. Trouble is, Australia’s National Construction Code provides false, and dangerous, hope. The sad truth is that any practical building that is exposed to an intense bushfire will probably burn down, whether it complies with Australia’s National Construction Code or not.

Across the U.S., States Are Bracing for More Climate-Related Disasters
Officials in states across the United States are calling for huge investments to mitigate the effects of wildfires, flooding, hurricanes, droughts, and other natural disasters made more devastating and frequent by climate change. Alex Brown writes that “Even states whose leaders don’t publicly acknowledge the existence of climate change, such as Texas and South Carolina, have applied for federal dollars citing ‘changing coastal conditions’ or ‘unpredictability’.”

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.

Reducing Risk, Empowering Resilience to Disruptive Global Change
Five-hundred-year floods. Persistent droughts and heat waves. More devastating wildfires. As these and other planetary perils become more commonplace, they pose serious risks to natural, managed, and built environments around the world. Assessing the magnitude of these risks over multiple decades and identifying strategies to prepare for them at local, regional, and national scales will be essential to making societies and economies more resilient and sustainable. A workshop highlights how MIT research can guide adaptation at local, regional, and national scales.

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.

Sea Level Rise: Major Economic Impact in the Absence of Further Climate Action
Rising sea levels, a direct impact of the Earth’s warming climate, is intensifying coastal flooding. The findings of a new study show that the projected negative economy-wide effects of coastal flooding are already significant until 2050, but are then predicted to increase substantially towards the end of the century if no further climate action on mitigation and adaptation is taken.

Climate Costs Smallest If Warming Is Limited to 2°C
Climate costs are likely smallest if global warming is limited to 2 degrees Celsius. The politically negotiated Paris Agreement is thus also the economically sensible one, Potsdam researchers find in a new study. Using computer simulations of a model by U.S. Nobel Laureate William Nordhaus, they weight climate damages from, for instance, increasing weather extremes or decreasing labor productivity against the costs of cutting greenhouse gas emission by phasing out coal and oil. Interestingly, the economically most cost-efficient level of global warming turns out to be the one more than 190 nations signed as the Paris Climate Agreement. So far however, CO2 reductions promised by nations worldwide are insufficient to reach this goal.

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.”

Sea-Level Rise Could Trigger Migration from Coastal Areas to Inland Cities in U.S.
When Hurricane Harvey slammed into the Texas coast in 2017, displaced residents flocked inland, trying to rebuild their lives in the disaster’s aftermath. Within decades, the same thing could happen at a much larger scale due to rising sea levels, says a new study. The researchers say that climate change-driven sea-level rise could trigger mass migration of Americans to inland cities.

2019: Economic Losses from Natural Disasters Top $232 billion in 2019
A new report from Aon shows that 409 natural catastrophe events of 2019 resulted in economic losses of $232 billion. Of that total, private sector and government-sponsored insurance programs covered $71 billion. The costliest individual peril was inland flooding, which caused economic losses globally of $82 billion, followed by tropical cyclone, at $68 billion.

Climate Change Means the U.S. Must Start Building Big Things Again
There used to be a time when the United States was adept at planning and building big projects – the highway system, putting a man on the moon, and more. Not anymore, James Temple writes. He notes that nearly every giant infrastructure project in the United States suffers from massive delays and cost overruns, and this is when they are not shut down altogether before completion. “The U.S. has become terrible at building big things, and negligent in even maintaining our existing infrastructure,” he writes, adding: “That all bodes terribly for our ability to grapple with the coming dangers of climate change, because it is fundamentally an infrastructure problem.”

Researcher Tests “Vaccine” Against Hate

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.
