headache for public health officials. To help address the challenge, a three-continent research consortium is evaluating a novel environmental crowdsourcing technique that relies on 53-cent test kits and the nation’s ubiquitous mobile phone service.

A fevered search for the next great high-energy, rechargeable battery technology is on....
Scientists who created a deicing film for radar domes have now refined the technology to work as a transparent coating for glass. The new work could keep glass surfaces from windshields to skyscrapers free of ice and fog while retaining their transparency to radio frequencies.
One sip of a perfectly poured glass of wine leads to an explosion of flavors in your mouth. Now, researchers have developed a nanosensor that can mimic what happens in your mouth when you drink wine. The sensor measures how you experience the sensation of dryness in the beverage. It has potential for both wine producers and research into the medicine of the future.
Up to 80 percent of sexually active women are infected by the human papillomavirus at some point in their lives and infection with specific "high risk" strains of HPV has an established link to cervical cancer. Current screening by smear test is invasive and time-consuming. Urine samples may be a viable alternative.
A new study into meat tenderness could refine the way people cook steak. Researchers conducted studies using microscopes to see what happens to meat cells while being cooked. They found that meat shrinks while cooking not once but twice.
By now, we've got all the details about Apple's latest iPhone. But what do you really know about the guts of the iPhone 6, or any smartphone for that matter?
Your color printer is an astonishing feat of precision engineering. It mixes four colors carefully enough to achieve more than a million different hues and shades. Then, each color is placed on the paper, with better than pinpoint accuracy. Now, a group of chemists is exploiting that precision engineering to screen millions of different chemical reactions.
Researchers have developed advanced molecular “sieves” that could be used to filter carbon dioxide and other greenhouse gases from the atmosphere. Newly developed synthetic membranes provide a greener and more energy-efficient method of separating gases, and can remove CO2 and other greenhouse gases from the atmosphere, potentially reducing the cost of capturing CO2 significantly.
Conditions on Earth for the first 500 million years after it formed may have been surprisingly similar to the present day, complete with oceans, continents and active crustal plates. This alternate view of Earth’s first geologic eon, called the Hadean, has gained substantial new support from the first detailed comparison of zircon crystals that formed more than 4 billion years ago with those formed contemporaneously in Iceland.
The very idea of fibers made of carbon nanotubes is neat, but scientists are making them neater— literally. The single-walled carbon nanotubes in new fibers line up like a fistful of uncooked spaghetti through a process designed by a chemist and his colleagues.
Researchers have devised a new simulation technique that reliably predicts the structure and behavior of different materials, in order to accelerate the development of next-generation batteries for a wide range of applications.
A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers had thought– and that the benefits of slow draining and charging may have been overestimated.
Parts of the flag that inspired America’s national anthem were snipped off and handed out as mementos. The Smithsonian has been reacquiring some of those fragments and adding to their collection, verifying them through high-tech methods.
Any explorers visiting Mars and the moon will have to boldly grow where no man has grown before. Setting up lunar or Martian colonies will require that explorers raise their own food. New research finds that simulated Martian soil supported plant life better than both simulated moon soil and low-quality soil from Earth.
Chemists have reported a new form of hydrogen production that is 30 times faster than the current state-of-the-art method. This is a major step forward in the production of hydrogen from water, which could lead to a new era of cheap, clean and renewable energy.
Chemists have discovered a new way of identifying peroxide-based explosives, which could make detection of suspect devices more cost-effective in the future.
Researchers have created the world’s largest DNA origami, which are nanoscale constructions with applications ranging from biomedical research to nanoelectronics. These origami can be customized for use in everything from studying cell behavior to creating templates for the nanofabrication of electronic components.
Salt crystals are often responsible when buildings start to show signs of ageing. Researchers have studied salt damage in greater depth and can now predict weathering processes more accurately.
New research findings point toward future approaches to fighting bacterial biofilms that foul everything from implantable medical devices to industrial pipes and boat propellers.
Despite being outlawed in 2012 in the U.S., the synthetic drugs known as bath salts— which really aren't meant for your daily bath— are still readily available in some retail shops, on the Internet and on the streets. To help law enforcement, scientists are developing a novel method that could be the basis for the first portable, on-site testing device for identifying the drugs.
The mere whiff of a dreamy perfume can help conjure new feelings or stir a longing for the past. But the creation of these alluring scents can also incur an environmental toll. That could change as scientists examine a more sustainable way to produce a key perfume ingredient and supply it to fragrance makers around the world.
For detecting cancer, manual breast exams seem low-tech compared to other methods such as MRI. But scientists are now developing an "electronic skin" that "feels" and images small lumps that fingers can miss. Knowing the size and shape of a lump could allow for earlier identification of breast cancer, which could save lives.
Researchers have explored the mechanisms behind the "browning reaction" during the spoilage of mushrooms. They were able to demonstrate that the enzyme responsible is already formed prior to fungal spoiling.
Chemistry Life Hacks are tips that can change your life, or at least the temperature of your beer.
A team of students created an inexpensive pad that can be inserted into diapers to detect dehydration and bacterial infections in infants. The product operates much like a home pregnancy test or urine test strip. Chemical indicators change color when they come in contact with urine from an infant who is suffering from dehydration or a bacterial infection.
Raw honey has been used against infections for millennia. So what is the key to its’ antimicrobial properties? Researchers have identified a unique group of 13 lactic acid bacteria found in fresh honey, from the honey stomach of bees. The bacteria produce a myriad of active antimicrobial compounds.
