Scientists have created a nanoscale detector that checks for and reports on the presence of hydrogen sulfide in crude oil and natural gas while they’re still in the ground.
In a new video, scientists explain the chemistry behind marijuana's high, and investigate...
A mineralogy researcher has discovered a new mineral that is unique in structure and composition...
A scientist is experimenting with "crumb" rubber— ground up tires of different-sized particles— to improve the rubberized road materials that a number of states are already using to enhance aging asphalt.
A team of scientists has successfully identified the age of 120,000-year-old Antarctic ice using radiometric krypton dating– a new technique that may allow them to locate and date ice that is more than 1 million years old.
A geostatistical approach for studying environmental conditions in stream networks and landscapes has been successfully applied at a valley-wide scale to assess headwater stream chemistry at high resolution, revealing unexpected patterns in natural chemical components.
A survey of emergency contraceptive pills in Peru found that 28 percent of the batches studied were either of substandard quality or falsified. Many pills released the active ingredient too slowly. Others had the wrong active ingredient. One batch had no active ingredient at all.
A team of inventors has created a new, more versatile version of their creation, Geckskin, which can adhere strongly to a wider range of surfaces, yet releases easily, like a gecko’s feet.
Bacillus anthracis, the bacteria that causes anthrax, is commonly found in soils all over the world and can cause serious, often fatal, illness in both humans and animals. Now, a credit card-sized anthrax detection cartridge makes testing safer, easier, faster and cheaper.
Researchers have shown the ability to grow high-quality, single-layer materials one on top of the other using chemical vapor deposition.
Electrically controlled glasses with continuously adjustable transparency, new polarization filters and even chemosensors capable of detecting single molecules of specific chemicals could be fabricated thanks to a new polymer that unprecedentedly combines optical and electrical properties.
Researchers have shown that humic substances act as fully regenerable electron acceptors which helps explain why large amount of methane are held in wetlands instead of being released to the atmosphere. However, there are worries that if this system is disrupted it may release large amounts of methane back into the atmosphere.
Researchers have developed a more effective ozone sensor than the ones currently available. The new sensor detects this gas faster and in lower amounts.
Two studies have found that the distinct flavor of strawberry has been linked to a specific gene, present in some varieties of the fruit– but not in others. The gene, FaFAD1, controls a key flavor volatile compound in strawberries called gamma-decalactone, which is described as fruity, sweet or peachy and contributes to fruit aroma.
Investigators have been analyzing data collected by a robotic submarine that completed its first successful scan of the seabed Thursday in the hunt for the missing Malaysian plane. The tests have ruled out that a nearby oil slick came from the aircraft.
Counterfeiters, beware: scientists are reporting the development of a new type of inexpensive barcode that, when added to documents or currency, could foil attempts at making forgeries.
On the scale of earth-friendly materials, you’d be hard pressed to find two that are farther apart than polyester and cork. In an unexpected twist, however, scientists are figuring out how to extract a natural, waterproof, antibacterial version of the former from the latter.
The EPA’s recommendations for treating water after a natural disaster or other emergencies call for more chlorine bleach than is necessary to kill disease-causing pathogens and are often impractical to carry out, a new study has found.
Scientists have solved a decades-old medical mystery– and in the process have found a potentially less toxic way to fight invasive fungal infections, which kill about 1.5 million people a year.
Personalized medicine took one step closer to reality recently with the development of plant-derived nanotubes. These nanotubes hone in on specific tissues in the body and deliver their cargo, in this study's case, a healthy gene to help override a dysfunctional copy.
Engineers have created new ceramic materials that could be used to store hydrogen safely and efficiently. They also have demonstrated that the compounds could be manufactured using a simple, low-cost manufacturing method known as combustion synthesis.
A new scalable, cheap, quick, repeatable and accurate tool uses a single drop of blood to diagnose even mild cases of asthma.
Researchers have succeeded in creating a surface on nanosized cellulose crystals that imitates a biological structure. The surface adsorbs viruses and disables them. The results can prove useful in the development of antiviral ointments and surfaces.
Zero-emission hydrogen fuel cell systems soon could be powering the forklifts used in warehouses and other industrial settings at lower costs and with faster refueling times than ever before.
The soil on Mars may be suitable for cultivating food crops. In a unique pilot experiment, a scientist tested the growth of 14 plant varieties on artificial Mars soil over 50 days. To his surprise, the plants grew well; some even blossomed.
A high-tech screening tool for cervical cancer is facing pushback from more than a dozen patient groups, who warn that the genetic test could displace a simpler, cheaper and more established mainstay of women's health: the Pap smear.
Delivering chemotherapy drugs in nanoparticle form could help reduce side effects by targeting the drugs directly to the tumors. Now, chemists have devised a new way to build nanoparticles that can carry and deliver three or more different drugs.
French investigators have begun taking DNA samples from 527 male students and staff at a high school— including boys as young as 14— as they search for the assailant who raped a teenage girl on the closed campus.
