After virtually eliminating arsenic as a useful tool for homicide, science now faces challenges in doing the same for natural sources of this fabled old “inheritance powder” that contaminates water supplies and food, threatening more than 35 million people worldwide.
Tiny versions of the reflectors on sneakers and bicycle fenders that help ensure the safety of runners and bikers at night are moving toward another role in detecting bioterrorism threats and diagnosing everyday infectious diseases, scientists said.
At some point, scientists may be able to bring back extinct animals, and perhaps early humans, raising questions of ethics and environmental disruption.
The neighborhood looks exceedingly normal: single-family homes and apartment buildings packed together, dogs barking from postage-stamp-size lawns, parents hustling down narrow sidewalks to fetch their children from school. But something with very dangerous potential lies below the surface.
More than three quarters of new, emerging or re-emerging human diseases are caused by pathogens from animals, according to the World Health Organization. But a widely accepted theory of risk reduction for these pathogens– one of the most important ideas in disease ecology– is likely wrong, according to a new study.
The Japanese utility that owns the tsunami-damaged nuclear power plant says it has detected a record 740,000 becquerels per kilogram of radioactive cesium in a fish caught close to the plant. That's 7,400 times the government limit for safe human consumption. The bottom-dwelling fish called a...
How do bone-eating worms reproduce? A new study sheds light on this question through a detailed observation of the postembryonic development and sexual maturation of Osedax worms, also known as “zombie worms.”
Scientists have identified patterns of epigenomic diversity that not only allow plants to adapt to various environments, but could also benefit crop production and the study of human diseases.
When it comes to evolution, humans can learn a thing or two from primeval sea lampreys. A team of scientists has presented an assembly of the sea lamprey genome– the first time the entire sequence has been decoded.
Based on aerial and ground-based measurements of droplet formation from ten different areas of the northern hemisphere, researchers report that organic coatings on particles don’t seem to significantly affect the rate at which droplets form. The researchers studied a wide range of particles, including organic, hydrocarbon-rich particles from the 2010 Deepwater Horizon oil spill in the Gulf of Mexico.
A new study to determine the effectiveness of rural lagoon systems found that sewage treatment lagoons remove most, but not all, of the pharmaceutical and personal care product and hormone contaminants from wastewater.
Digesting lignin, a highly stable polymer that accounts for up to a third of biomass, is a limiting step to producing a variety of biofuels. Researchers have figured out the microscopic chemical switch that allows Streptomyces bacteria to get to work, breaking lignin down into its constituent parts.
Researchers have discovered how a new class of antimalarial drugs, spiroindolones, kills the malaria parasite, showing that the drugs block a pump at the parasite surface, causing it to fill with salt.
The richer the assortment of amphibian species living in a pond, the more protection that community of frogs, toads and salamanders has against a parasitic infection that can cause severe deformities, including the growth of extra legs, according to a new study.
The research center largely responsible for launching the "green revolution" of the 1960s is now planning to develop more genetically-modified seeds to help farmers in the developing world grow more grain in the face of changing climate conditions and increased demand. Donations of $25 million...
Researchers have discovered that a gold-dwelling bacterium excretes a small molecule capable of forming solid gold.
Wheat breeders have developed a higher-yielding soft white winter wheat, known as Kaseberg, that is also resistant to the disease stripe rust.
Plant-based and algae-based biofuels are becoming more profitable than ever, leading to more green backs for opportunists of the green age.
METTLER TOLEDO introduces a new balance range, NewClassic, to replace the company's current Classic portfolio. A metal housing offers reliable protection and is resistant to chemicals.
Cellexus announced availability of the 50 litre format of the CellMaker Regular, a single use, disposable bioreactor system providing increased ODs and improved yields of soluble protein when compared with flask grown cultures.
SANYO Biomedical and Environmental Solutions (SANYO), a division of SANYO North America Corporation, offers the Sterisonic GxP, MCO-19AIC(UVH) Cell Culture Incubator
CARON introduces a newly designed 25 cu. ft. Insect Growth Chamber (Model 6025). The Insect Growth Chamber is another product new to CARON's 25 cu. ft. family of products containing many earth-friendly and customer-friendly features.
The Waters SYNAPT G2 System features new QuanTof and enhanced High Definition MS technologies intended to accelerate scientists toward their research goals.
GE Healthcare offers next generation HiPrep 16/10 columns. The new column hardware has been redesigned to give the same high performance, reproducibility, and ease-of-use, while using significantly less plastic.
