Iowa State researchers improving plastics made from corn and soy proteins

...e field tests. The researchers' plastics aren't quite ready to leave the laboratory. Grewell said he's working on production recipes, processing techniques and ultrasonics applications. Kessler will also work to characterize the plastics' strength plus its thermal and mechanical properties. Working w...

Plant-cell-produced technologies-cutting edge approach to bringing solutions to the market

...in poultry. The latest technology could be applied quite quickly to other diseases - with avian flu a prime target. This approval represents an innovative milestone for the company and the industry. The Dow AgroSciences Concert Plant-Cell-Produced System represents a new category of plant-made vaccines. ...

Three-in-one virus killer prevents common, often fatal infections

..."To make dramatic recoveries like these was really quite something." The research team drew cells from bone marrow donors and "trained" T-cells to target the three viruses before injecting them into transplant recipients. "Drugs only control the virus. They don't cure the underlying problem," said Bo...

Trotting with emus to walk with dinosaurs

...pt, is that many mysterious dinosaur tracks became quite easily understood when a live animal was seen in action. Breithaupt will be presenting some of his team's emu track discoveries on Wednesday, 25 October at the Annual Meeting of the Geological Society of America in Philadelphia. Theresearch was f...

Cougar predation key to ecosystem health

...e a similar climate and their ecosystems should be quite similar," Ripple said. "But instead they are very different, and we hypothesize that the long-term lack of cottonwood recruitment associated with stream-side areas in Zion Canyon indicates the effects of low cougar and high deer densities over many d...

How many genes does it take to learn? Lessons from sea slugs

...euron from the next, even though they may function quite differently. Molecular analyses of Aplysia neuronal genes are shedding light on these elusive processes. In 2000, senior author Eric Kandel, M.D., of Columbia University in New York shared the Nobel Prize in Physiology or Medicine for his work usi...

Stormy days ahead for coral reefs

...e in stormy seas. Even the vulnerable species are quite stable when they're young," says Dr Connolly. "They also tend to grow and mature quickly, so the species can recover before the next big storm arrives." However, one effect of the increased production of greenhouse gases is an increase in the ...

Microcapsules like it hot and salty

...his continuous switching between the two states of quite different capsule sizes expands the range of possible uses for the Potsdam microcapsules enormously. As well as being used as medicine transporters, conceivable applications include using the capsules as a component of car paint which releases a corr...

Halving daily cigarette quota has no health benefit

...ry measure in smoking cessation, this study proves quite clearly that the only safe way out of the risk caused by smoking is to quit, say the authors. They base their findings on more than 51,000 men and women, all of whom were aged between 20 and 34 at the start of the study. Participants were init...

Radiologists attempt to solve mystery of Tut's demise

...nd free the gold mask, which was tightly glued and quite adherent to the body, by using some metal instruments that broke the thin, fragile piece of bone that lies immediately underneath the bone defect in the skull base through which the spinal cord emerges," Dr. Selim said. Dr. Selim's team did not e...

On the golf tee or pitcher's mound, brain dooms motion to inconsistency

...y your golf swings, fastballs or free throws don't quite turn out the same way each time, even after years of practice, there is now an answer: It's mostly in your head. That's the finding of new research published in the Dec. 21 issue of the journal Neuron by electrical engineers at Stanford University. ...

Paying attention sets off symphony of cell synchronization

...patterns were fairly dim. At other times they were quite bright. EEG responses from the participants showed more brain activity for brighter stimuli, as expected, but responses also varied depending on attention. The patterns of these brain waves allowed the investigators to obtain a thorough description...

Wolves are suffering less from inbreeding than expected

...kind of detailed information about wild animals is quite unique, but a necessary prerequisite for calculations of so called inbreeding coefficients. - The inbreeding coefficient is a measure of the proportion of the DNA that is inbred. It varies between 0 and 100%. If a brother and sister are mating, th...

Buildup of damaged DNA in cells drives aging

...athways in progeroid and normal older mice, we are quite confident that DNA damage plays a significant role in promoting the aging process. The bottom line is that avoiding or reducing DNA damage caused by sources such as sunlight and cigarette smoke, as well as by our own metabolism, also could delay agin...

Coral reefs are increasingly vulnerable to angry oceans

Changing length of days reverses how estrogen affects aggressiveness in mice

...d neuroscience at Ohio State University. "It is quite a surprising finding." The study is also important because it is one of the few that has shown how hormones other than testosterone can affect aggression in mammals. "This goes against the common belief that testosterone is the hormone that reg...

Researchers give name to ancient mystery creature

Researchers barcode DNA of Venice museum's vast fungi collection

...i that represent 6,000 species - many of which are quite rare - are housed at the Venice Museum of Natural History, a partner with UC Berkeley for this ambitious project. The collection also is one of the largest in Europe. The project was publicly announced in Italy today (Wednesday, Dec. 13) at the pr...

Mayo Clinic: Gene expression profiling not quite perfected in predicting lung cancer prognosis

...btle difference are often overlooked, which may be quite relevant biologically to clinical questions. The authors of the study recommend that medical scientists engaged in gene expression profiling should: Clearly define a study aim. The main focus in microarray studies should explore the molec...

Does natural selection drive the evolution of cancer?

...hemotherapy to a population of tumor cells, you're quite likely to have a resistant mutant somewhere in that population of billions or even trillions of cells. This is the central problem in oncology. The reason we haven't been able to cure cancer is that we're selecting for resistant tumor cells. When we ...
