Bacteria ferry nanoparticles into cells for early diagnosis, treatment

...e bacteria with "linker molecules." "The use of commercially available polystyrene nanoparticles makes this delivery system much simpler to implement than previous alternatives," Bashir said. This new delivery system also is more efficient than other experimental techniques using viruses and bacteria. "W...

Plastic that grows on trees

...e, is nature’s most abundant sugar. “But getting a commercially viable yield of HMF from glucose has been very challenging,” Zhang said. “In addition to low yield until now, we always generate many different byproducts,” including levulinic acid, making product purification expensive and uncompetitive with petrol...

Warning from Asian bees

...of it. Asian bees remain feral, cannot be hived commercially and will attack Australian bees and rob their hives. Compared to the home breed, Apis mellifera, the intruders are nowhere near the same league in the volume of honey they produce. In the recent experience of Papua New Guinea and the Solomon Islan...

Modified mushrooms may yield human drugs

...being a choice platform for the mass production of commercially valuable proteins," said Charles Peter Romaine, who holds the John B. Swayne Chair in spawn science and professor of plant pathology at Penn State. "Mushrooms could make the ideal vehicle for the manufacture of biopharmaceuticals to treat a broad ar...

New vaccine prevents CMV infection and disease in mice

... a human vaccine. If successful, an FDA-approved, commercially licensed hCMV vaccine could be administered to specific at-risk populations, such as females prior to child-bearing years, day care providers, organ transplant recipients, or as part of regular childhood immunizations. “This approach may also be ...

Novel system developed to turn data into real-time, interactive 3-D images

...se processes. The new system will be available commercially and improve upon current technology, in terms of image quality and cost-effectiveness. It is compatible with all imaging devices, will translate and display data immediately and in its entirety, and allows for user-friendly manipulation of the data f...

Dinosaur hearing, listening to muscle noise, quieter cubicles

...ts such as swimmers. The SDSN is already available commercially for wide-scale deployment (2pEA1). Two papers presented by scientists from Stevens Institute of Technology, Hoboken (papers 2aEA4 and 2aEA5) discuss acoustic measurements in New York's Hudson River. Details of acoustic noise produced by ship traffic ...

Biodiesel study targets cleaner air, cleaner engines

...trogen oxides and particulate matter. Although commercially available, biodiesel has never been tested on agricultural machinery in Canada and has not yet been widely used by farmers. It is hoped the research results ?expected in early May ?will help increase demand for biodiesel, which in turn will increase ...

Ancient genes used to produce salt-tolerant wheat

...ead wheat is in advanced field trials and could be commercially available in three years. Even better durum wheats are in development and the program has been expanded to include bread wheat. "Bread wheat is quite tolerant to salt, but we think it too can be improved. Our aim is to eventually produce wheats ab...

Mimicking how the brain recognizes street scenes

...gap between an intriguing idea or technology and a commercially viable concept. Recognizing Scenes The IEEE paper describes how the team "showed" the model randomly selected images so that it could "learn" to identify commonly occurring features in real-word objects, such as trees, cars, and people. In so...

Misclassified for centuries, medicinal leeches found to be 3 distinct species

Genetic research has revealed that commercially available medicinal leeches used around the world in biomedical research and postoperative care have been misclassified for centuries. Until now, the leeches were assumed to be the species Hirudo medicinalis, but new research reveals they are actuall...

UW launches study testing adult stem cells for heart damage repair

...d under the skin in the arm, thigh or abdomen of a commercially produced protein (granulocyte colony stimulating factor). The protein helps to release blood-forming CD34+ cells from a subject's bone marrow into the bloodstream. Then, investigators use a cell separation system to remove from the subject's bloo...

Cancer tip -- Nanoparticles can damage DNA, increase cancer risk

... nanoparticle types because they are commonly used commercially ?in electronics, textiles and sporting goods ?and easy to work with in the laboratory setting. "We observed both dose-dependent and time-dependent increases in DNA damage in breast cancer cells exposed to either aqueous colloidal silica or C60 f...

Long-lived deep-sea fishes imperiled by technology, overfishing

Many commercially prized fish from the depths of the world's oceans are severely threatened by over-fishing and the species' ability to recover is constrained by the fishes' long lifespans and low reproductive success, a panel of experts said today at the annual meeti...

New test for most virulent HPV strains under study

...PV. A test that detects 13 types of HPV already is commercially available, so the new test could become the second non-type-specific HPV test on the market. Dr. Ferris, who was involved in early studies of the HPV vaccines, hopes the new tests will one day provide better options for screening for the most comm...

Twenty of world's 162 grouper species threatened with extinction

...ng Kong was the first systematic assessment of the commercially important species, said Dr. Yvonne Sadovy, Chair of the IUCN Grouper and Wrasse Specialist Group and Associate Professor at HKU. “The results are worrying and highlight the urgent need for fishery management, more effective marine protected areas ...

New science of metagenomics 'will transform modern microbiology'

...t off disease-causing microbes. Microbes are used commercially for many purposes, including making antibiotics, remediating oil spills, enhancing crop production, and producing biofuels. Historically, microbiology focused on the study of individual species of organisms that could be grown in a laboratory and ...

Novel experiment documents evolution of genome in near-real time

...y design processes to optimize bacteria to perform commercially important processes. Aside from its commercial potential, experimental evolution of bacterial strains is also useful for refining the theory of evolution and the related process of natural selection of individuals with traits that convey a selective...

Transplanted brain cells hold promise for Parkinson's disease

... They did additional studies in test tubes, taking commercially available rat and human dopaminergic cells, exposing them to neurotoxins and then to stem cell factors. Stem cell factor protected cells in a dose-dependent fashion. "The more stem cell factor, the better the protection," Dr. Borlongan says. When the...

New sunscreen ingredient to heal sunburn and help prevent skin cancer

...three years of research, the team has designed two commercially attractive prototypes which are currently in laboratory trials. The prototypes contain 'caged' iron binding sites which release the chelators only in response to high doses of UV light, thus avoiding toxicity to cells. The new sunscreens contain...
