Flights increase rain and snow near airports
Areas near commercial airports experience a measurable increase in rain and snow when aircraft take off and land under certain atmospheric conditions; when planes fly through certain mid-level clouds, they force nearby air rapidly to expand and cool; this causes water droplets to freeze to ice and then turn to snow as they fall toward the ground, often leaving behind odd-shaped gaps in the clouds

"Sensing skin" to monitor concrete infrastructure health inexpensively
In 2009, the American Society of Civil Engineers (ASCE) assigned the grade D to the overall quality of infrastructure in the United States and said that ongoing evaluation and maintenance of structures was one of five key areas necessary for improving that grade; civil engineers recently proposed a new method for the electronic, continual monitoring of structures

Farm animal disease to increase with climate change
Researchers looked at changes in the behavior of bluetongue — a viral disease of cattle and sheep — from the 1960s to the present day, as well as what could happen to the transmission of the virus forty years into the future; they found, for the first time, that an outbreak of a disease could be explained by changes to the climate

Bomb-proof bag for planes' luggage compartment developed
The blast-absorbing bag, named the Fly-Bag, features multiple layers of novel fabrics, composites, and coatings and is designed to be filled with passenger luggage and then placed in the hold of a plane; if one of the pieces of luggage inside the Fly-Bag had a bomb in it and the bomb exploded during the flight, the resulting blast would be absorbed by the bag owing to its complex fabric structure, preventing damage to the plane; fundamental to the design of the bag is the internal elastomeric coating and impregnation of fabric with Shear Thickening Fluids (STF); STFs work by increasing in viscosity in response to impact

Disappearing La Niña blamed for U.S. disastrous weather since January
La Niña and El Niño are opposite extremes of a great Pacific oscillation; every two to seven years, surface waters across the equatorial Pacific warm up (El Niño) and then they cool down again (La Niña); each condition has its own distinct effects on weather; La Niña was strong in December, but disappeared in January, leaving nothing to constrain the jet stream; the jet stream took advantage of the new freedom — with disastrous results for the weather

New building material could help solve bridge woes
With infrastructure in the United States rapidly aging and in need of repair, new building materials made in Maine that make bridges cheaper, lighter, and more durable could help cash starved states undertake critical infrastructure investment; using lightweight hybrid composite beams, the Maine Department of Transportation (MDOT) has just completed the largest composite bridge in the world; the new bridge is projected to last at least 100 years; the material’s weight, cost, and durability have generated a lot of interest across the country

High tech more effective than tax climate in driving states' economic growth
Race-to-the-top policies are generally defined as those involving investments in education, entrepreneurship, and infrastructure; race-to-the-bottom policies involve competition among the states for jobs by using lower taxes and industrial recruitment incentives; researchers find that states with more technology classes in school, higher domain name registrations, and more people online tended to economically outperform states with a lower emphasis on technology

Official dispels government green procurement regulation myths
The U.S. government owns or manages one in five acres in the United States, and is the largest domestic user of electricity; it is also one of the largest consumers of resources in the United States, purchasing on average $535 billion worth of goods each year; In 2009 President Obama issued an executive order requiring that all government agencies establish and implement plans to increase their environmental performance; speaking at the 2011 Security Industry Association’s (SIA) Government Summit to an audience of security professionals, a government official sought to clarify myths surrounding the government’s new green procurement regulations and assured government service providers that the rules would not drastically affect a company’s existing practices

China deploys drought relief team to country's north
China’s northernmost provinces are still suffering from a prolonged drought that has been the country’s worst in fifty years; in the northern provinces and the autonomous regions of inner Mongolia more than 11.67 million people and 3.62 million livestock have been affected by the drought; nearly six million acres of the region’s crops have also been hit hard by the drought; the government has declared it a level-four emergency, the highest level, and is launching a full out emergency response plan to aid the beleaguered region

Nanowire-based sensors detect volatile organic compounds
Researchers have made nano-sized sensors that detect volatile organic compounds — harmful pollutants released from paints, cleaners, pesticides, and other products — which offer several advantages over today’s commercial gas sensors, including low-power room-temperature operation and the ability to detect one or several compounds over a wide range of concentrations

New commuting method: Personal Aerial Vehicles
Researchers in Germany have an idea for solving the growing congestions in urban centers: a Personal Aerial Vehicles (PAVs) for traveling between homes and working places; the PAVs will fly at low altitude in urban environments, thus making it unnecessary to change current air-traffic control regulations

NFL in search of new helmets to reduce brain trauma
Researchers at the NFL’s Southern Impact Research Center are currently exploring ways to install sensors on helmets to measure the amount of head trauma players receive; league officials hope that the sensors can eventually be installed on all helmets to provide accurate data that can then be used to adjust game rules and construct better helmets that will reduce the number of concussions

Revolutionizing Resource Renewal: Scaling Up Sustainable Recycling for Critical Materials
Permanent magnets, which retain magnetic properties even in the absence of an inducing field or current, are used extensively in clean energy and defense applications. Rare earths are challenging to access because they are scattered across Earth’s crust, yet they are key components in many modern technologies. Recycled rare earths can be used to make new permanent magnets, accelerate chemical reactions and improve the properties of metals when included as alloy components.
Saving Seconds, Saving Lives: NIST-Funded Challenge Crowns Winners in 3D Tracking Technology
NIST has awarded $1.9 million to six teams for innovative 3D tracking solutions in the final phase of a competition. The winning designs combine localization and biometric monitoring, using sensors affixed to first responders’ equipment. This competition is part of an $8 million NIST-funded initiative to address first responders’ need for improved tracking in emergency settings where GPS falls short.
Number of People Affected by Tropical Cyclones Has Increased Sharply Since 2002
The number of people affected by tropical cyclones has nearly doubled from 2002 to 2019, reaching nearly 800 million people in 2019, according to a new study. More people are affected by tropical cyclones in Asia than any other region, but every affected world region saw an increase in the number of people exposed to tropical cyclones, which are expected to become more intense and possibly more frequent as the climate warms.
