Rapid, low-cost, point-of-care flu detection demonstrated
The novel H1N1 flu pandemic in 2009 underscored weaknesses in methods widely used to diagnose the flu, from frequent false negatives to long wait times for results; scientists demonstrate a prototype rapid, low-cost, accurate, point-of-care device that promises a better standard of care

Some flame retardants make fires more lethal
Almost 10,000 deaths from fires occur in industrialized countries worldwide each year, including about 3,500 in the United States; scientists find that widely used flame retardants added to carpets, furniture upholstery, plastics, crib mattresses, car, and airline seats and other products to suppress the visible flames in fires are actually increasing the danger of invisible toxic gases that are the No. 1 cause of death in fires

A swarm of small satellites to deflect menacing asteroids
New research suggests that the best way to divert an asteroid hurtling toward Earth is using a swarm of relatively small satellites flying in formation and cooperatively firing solar-powered lasers onto an asteroid; this would be a more effective way than the current methods being contemplated, which are focused on large unwieldy spacecraft

Machine can tell when a human being is lying
In a study of forty cases, a computer correctly identifies liars more than 80 percent of the time, a better rate than humans with the naked eye typically achieve in lie-detection exercises

New plastics mimic human skin: they “bleed” when scratched, then heal
Plastics have become so common, replacing steel, aluminum, glass, paper, and other traditional materials because they combine desirable properties such as strength, light weight, and corrosion resistance; a new genre of plastics that mimic the human skin’s ability to heal scratches and cuts offers the promise of endowing military and first response gear – and consumer goods – with self-repairing surfaces

1930s technology to become 21st century tool against CO2 emissions
Human activity releases 30 billion tons of carbon dioxide into the air each year; a new approach to dealing with the problem has a back-to-the-future glint, leveraging technology that the petroleum industry has used since the 1930s to remove carbon dioxide and other impurities from natural gas

Earth's crust is slowly being destroyed
New research shows that the Earth’s crust is now undergoing high rates of destruction; the research shows the sharp decrease in the growth of the continental crust indicates a dramatic change in the way the Earth has generated and preserved this crust in the last 4.5 billion years

Planetary exploration vehicle for earthly search-and-rescue missions
A researcher develops a NASA-sponsored autonomous lake lander for the purpose of exploring lakes on distant planets; this mission is many years in the future; in the meantime, the vehicle is ready to deploy on missions related to defense and security, such as harbor surveillance and cleanup operations of littoral munitions dumps and mines; it is also ideal for search-and-rescue operations in oceans, lakes, and hazardous environments, as well as for environmental research projects

The Transboundary Agreement is not just about the cost of gas and the environment
The Transboundary Agreement, which the United States and Mexico reached on 20 February, regulates oil and gas development in the Gulf of Mexico; before the agreement is ratified, there is a need to address serious security issues related to building more oil rigs in the Gulf – for example, the fact that the Mexican government cannot control its powerful criminal organizations, and that it will be easy for terrorists in a small boat to overrun one of these deepwater rigs

Electricity from trees
Plants have long been known as the lungs of the earth, but a new finding has found they may also play a role in electrifying the atmosphere; scientists found the positive and negative ion concentrations in the air were twice as high in heavily wooded areas than in open grassy areas, such as parks

Confirmed: oil from Deepwater Horizon disaster entered food chain
For months, crude oil gushed into the water at a rate of approximately 53,000 barrels per day; new study confirms that not only did oil affect the ecosystem in the Gulf during the blowout, but it was still entering the food web after the well was capped
