Alien apocalypse: Can any civilization survive climate change?
In the face of climate change, deforestation and biodiversity loss, creating a sustainable version of civilization is one of humanity’s most urgent tasks. But when confronting this immense challenge, we rarely ask what may be the most pressing question of all: How do we know if sustainability is even possible? Astronomers have inventoried a sizable share of the universe’s stars, galaxies, comets, and black holes. But are planets with sustainable civilizations also something the universe contains? Or does every civilization that may have arisen in the cosmos last only a few centuries before it falls to the climate change it triggers?

New tool to detect deadly chemical weapon agents: Butterflies
Every spring caterpillars shed their cocoons, emerging as butterflies. This timeless symbol of change is now being applied to enhanced chemical detection for U.S. soldiers. Researchers from the military service academies, funded by the Defense Threat Reduction Agency’s Chemical and Biological Technologies Department, are using butterflies to detect trace amounts of chemical warfare agents with increased precision and speed.

Data science improves lie detection
Someone is fidgeting in a long line at an airport security gate. Is that person simply nervous about the wait? Or is this a passenger who has something sinister to hide? Even highly trained Transportation Security Administration (TSA) airport security officers still have a hard time telling whether someone is lying or telling the truth – despite the billions of dollars and years of study that have been devoted to the subject. Researchers are using data science and an online crowdsourcing framework called ADDR (Automated Dyadic Data Recorder) to further our understanding of deception based on facial and verbal cues.

Bolstering the body’s defenses against public health, national security threats
Military service members, first responders, and civilian populations face severe threats from pathogens with pandemic potential, toxic chemicals, and radioactive materials, which can all quickly and powerfully overwhelm the body’s innate defenses. And though significant public and private investment has been focused on the development of traditional medical countermeasures such as drugs, vaccines, and biologics to guard against the worst effects of these health threats, current countermeasures are often limited in their effectiveness and availability during emergencies. PREPARE aims to develop new class of generalizable medical countermeasures that safely and temporarily tune activity of protective genes.

Floridians to face more frequent, intense heatwaves
By the late twenty-first century, if atmospheric greenhouse gas concentrations reach worst-case projections, Floridians could experience summer heatwaves three times more frequently, and each heatwave could last six times longer than at present, according to new research. “More extreme heatwaves in Florida would have profound impacts on human health as well as the state’s economy,” says a researcher.

China sonic attack: how sound can be a weapon
Reports of “sonic attacks” in China, and previously in Cuba, have left many wandering whether sonic weapons could be targeting U.S. diplomats. Victims have reportedly experienced mild brain injuries with symptoms including “subtle and vague, but abnormal, sensations of sound and pressure.” Little is known for definite, but the symptoms do suggest that some sort of sonic interference could have taken place. It is unlikely to be the result of a deliberate “sonic attack.” Instead, these injuries are probably the side effects of intrusive surveillance.

Climate change could increase arable land, agricultural feasibility in northern hemisphere
Climate change could expand the agricultural feasibility of the global boreal region by 44 percent by the end of the century, according to new research. However, the scientists warn that the same climate trends that would increase land suitable for crop growth in that area could also significantly change the global climatic water balance – negatively impacting agriculture in the rest of the world.

Will London run out of water?
The U.K.’s Environment Agency warns in a new report that England could suffer major water shortages by 2030 and that London is particularly at risk. The BBC agrees, placing London on its recent list of 11 cities most likely to run out of drinking water along with the likes of Cape Town, where an ongoing water crisis has caused social and economic disruption. There are limits to what can be achieved just by fixing leaky pipes or getting people to water their lawns less often. Though such measures are useful, they will not safeguard London’s water supplies against the more extreme combinations of growth and climate change.

Antibiotic resistance rise tied to hotter temps
Could a warming climate be one of the factors bringing the world closer to the “post-antibiotic” era that infectious disease experts have been warning about? That’s one of the questions raised by a new study that explores the role that climate and other factors play in the distribution of antibiotic resistance in the United States.

Reducing fire hazards from materials
Fire researchers will tell you that there’s a simple solution for reducing fire hazards: eliminate flammable materials. If it doesn’t burn, the experts say, then there won’t be a fire. Of course, that option isn’t very practical or realistic; after all, who wants to sit on a block of cement when you can have a cushiony recliner? NIST offers a better strategy for reducing the thousands of deaths and injuries and billions of dollars in damage resulting from the more than a million fires each year in the United States.

Using proteins from bones to identify people
When a team of researchers led by Lawrence Livermore National Laboratory (LLNL) developed a new biological identification method that exploits information encoded in proteins, they thought it could have multiple applications. Nearly two years later, they’ve turned out to be right. One possible important application for using protein markers from human bones could be to help determine the identity of partial remains from catastrophic events, such as plane crashes, fires or the 9/11 terrorist attacks.

Future hurricanes: Stronger, slower, wetter
Scientists have developed a detailed analysis of how twenty-two recent hurricanes would be different if they formed under the conditions predicted for the late twenty-first century. While each storm’s transformation would be unique, on balance, the hurricanes would become a little stronger, a little slower-moving, and a lot wetter.

Artificial “nose” helps find people buried by earthquakes, avalanches
Trained rescue dogs are still the best disaster workers – their sensitive noses help them to track down people buried by earthquakes or avalanches. Like all living creatures, however, dogs need to take breaks every now and again. They are also often not immediately available in disaster areas, and dog teams have to travel from further afield.. Scientists have developed the smallest and cheapest ever equipment for detecting people by smell. It could be used in the search for people buried by an earthquake or avalanche.

Interior releases 2018’s final list of critical minerals
The Department of the Interior last week published a list of 35 mineral commodities considered critical to the economic and national security of the United States. This list will be the initial focus of a multi-agency strategy due in August this year, which aims to break America’s dependence on foreign minerals.
