New study reports hotel guests at risk from carbon monoxide poisoning

...0 people every year in the United States. Although inexpensive CO detectors have been available since 1989, their use in hotels, motels and resorts is not widespread. In fact, while every guest room in the U.S. must contain a smoke detector, there is no federal mandate for CO detectors. In a study published in t...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...ckly became the treatment of choice because it was inexpensive − now seven cents a dose − and needs no refrigeration. The drug works by preventing heme crystallization, which destroys the parasite by building up toxic levels of non crystalline heme. But because of the overuse of chloroquine, isolates of P...

Mutating the entire genome

A new, fast and inexpensive way to mutate genes and large, non-gene pieces of DNA has been developed by University of Utah geneticists. They tested the method by mutating a gene involved in bone formation, resulting in short, malformed tail and limbs in the mutant mouse on the ...

Researchers attach genes to minichromosomes in maize

... not otherwise be possible, from improved crops to inexpensive pharmaceutical production to other applications in...In addition, minichromosomes could be used for the inexpensive production of multiple foreign proteins and metabolites useful for medical purposes. Because of thei...

No magic tomato? Study breaks link between lycopene and prostate cancer prevention

...ng, since lycopene might have offered a simple and inexpensive way to lower prostate cancer risk for men concerned about this common disease," said Ulrike Peters, Ph.D., M.P.H., of the Fred Hutchinson Cancer Research Center. "Unfortunately, this easy answer just does not work." Previous studies suggested tha...

Nanotechnology meets biology and DNA finds its groove

... Now, however, scientists have developed a quick, inexpensive and efficient method to extract single DNA molecul...ues Schwartz, is that the system is comprehensive, inexpensive and simple enough to lend itself to large-scale efforts to analyze DNA. "It's a simple technology...

Cheaper, better disease treatments expected from faster approach to developing antibodies

...Biotechnology. Bacteria are easy to grow in an inexpensive broth. As a result, harmless forms of the bacterium E. coli have already been used as factories to produce antibodies (protective proteins of the human body that fight viruses, cancer cells and other harmful agents). However, previous approaches requ...

Producing medicines in plant seeds

...sing plants to produce useful proteins could be an inexpensive alternative to current medicine production methods. Researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) at Ghent University have succeeded in producing in plant seeds proteins that have a very strong resemblance to antibod...

Can engineered immune cells stop AIDS?

...s that gene therapy could now be carried out as an inexpensive procedure, able to be considered even in the less-developed world," Wang and his coauthors wrote. That's good news for the World Aids Foundation, which announced on World AIDS Day (Dec. 1, 2006) that the disease is on the rise again. More than 39 m...

Study shows antibiotic-resistant bacteria responsible for increase in muscle infections

...used by Staphylococcus aureus have been treated by inexpensive antibiotics in the penicillin and cephalosporin family. Some years ago, strains resistant to these drugs, called methicillin-resistant Staphylococcus aureus (MRSA) appeared in hospitalized patients. Recently, however, newer forms of MRSA began to st...

Researchers develop technologies to devour food pathogens

Purdue researchers are developing two inexpensive technologies that may be able to prevent future food-borne illness, such as the recent outbreak of E. coli in contaminated spinach. Together, these technologies rapidly detect and eradicate food-borne pathogens. The first method uses a laser to de...

Nano-devices hold promise for early-stage cancer detection

... "The ultimate goal is to develop reliable and inexpensive detection and imaging products that can be used in a doctor’s office or possibly even at home as part of a regular exam," said Steve Hranilovic, assistant professor of electrical and computer engineering at McMaster. "This would address wait-time an...

Bacterial protein shows promise in treating intestinal parasites

...ability of medicines that are safe, effective, and inexpensive to manufacture," said Michael Cappello, one of two principal authors of the study and a professor of pediatrics and epidemiology & public health at Yale School of Medicine. "We believe that Bt crystal proteins not only meet, but exceed these esse...

Finding the right mix: A biomaterial blend library

K-Staters design and build a low-cost remote sensing tool for environmental studies

...e University research team is prototyping a small, inexpensive remote-control plane as a sensing tool, also known as an unmanned aerial vehicle, to collect environmental data. The team plans to test it over the Konza Prairie Biological Station near Manhattan this summer. If the sensing tool performs as the team...

Defense peptide found in primates may block some human HIV transmissions

...to growing anthrax vaccine in tobacco plants. An inexpensive way to produce the drug with only a small amount of tobacco would help to make it accessible in areas such as Southeast Asia, Africa and the Caribbean where the disease spreads most quickly. "If we could develop retrocyclin in plants and produce en...

Finding paves way for better treatment of autoimmune disease

... with an affinity for alcohol has yielded a rapid, inexpensive way to make large numbers of immune cells that work like beat cops keeping misguided cells from attacking the body. The ability to easily make large numbers of these cells opens the door to improved treatment and a better understanding of autoimmun...

Sticky surfaces turn slippery with the flip of a molecular light switch

...t stick as well," Belfort says. Operators need an inexpensive way to clean these membranes while they are still in place, rather than periodically removing them from the application environment, Belfort says. But currently the only cleaning options involve expensive chemicals or labor-intensive procedures that ...

MIT 'seeing machine' offers hope to blind

An MIT poet has developed a small, relatively inexpensive "seeing machine" that can allow people who are blind, or visually challenged like her, to access the Internet, view the face of a friend, "previsit" unfamiliar buildings and more. Recently the machine received positive feedback from 10 visually chal...
