Green diesel: New process makes liquid transportation fuel from plants

...d distilling corn. As a result, ethanol production creates 1.1 units of energy for every unit of energy consumed. In the UW-Madison process, the desired alkanes spontaneously separate from water. No additional heating or distillation is required. The result is the creation of 2.2 units of energy for every un...

Retina adapts to seek the unexpected, ignore the commonplace

...rain, but not very faithfully. Instead, the retina creates a cartoonist's sketch of the visual scene, highlighting key features while suppressing the less interesting regions." These findings provide evidence that the ultimate goal of the visual system is not simply to construct internally an exact reproduc...

Toxic flood lifts lid on common urban pollution problem

...nts. Planting vegetation and especially trees also creates aesthetically pleasing buffer zones, providing storm water flooding control and other benefits. Finally, cities can use high-tech street sweeping equipment that is very effective at capturing pavement contaminants. "If you pick up this potentially ...

Gene loss accelerates aging

...e p63 protein in the right cells at the right time creates a balance that enables organisms to live relatively cancer-free for a reasonably long time," says Mills, who adds that this is the first time the p63 gene has been implicated in aging. "I first presented these results at a meeting in Tuscany. I don'...

Ants, not evil spirits, create devil's gardens in the Amazon rainforest, study finds

...chista schumanni, which nests in D. hirsuta stems, creates devil's gardens by poisoning all plants except its hosts with formic acid. By killing other plants, M. schumanni provides its colonies with abundant nest sites--a long-lasting benefit, as colonies can live for 800 years." Devilish ants Most tropi...

Device traps, disables harmful bacteria

...erapy pools, many bioaerosols researchers believe, creates harbors that enhance the aerosolization of microorganisms, including strains of Legionella and Mycobacterium, that can cause diseases such as "lifeguard lung." "The results of this study suggest that a reasonable reduction in bioaerosol concentratio...

Study: Predatory dinosaurs had bird-like pulmonary system

...e lungs twice during ventilation. This system also creates holes in the skeleton of birds, which has led to a popular notion that birds have "air in their bones," O'Connor said. The new study, which examined how the air system invades the skeleton in areas such as the neck, chest and hips, finds similaritie...

Nose odors and mouth odors: The brain distinguishes

...factory referral induced by retronasal stimulation creates a differential reward context for food but not for non-food odors by signaling availability versus receipt of food," they concluded. "Because the current study tested only one food, future experiments are needed to determine whether other food odors ...

New Lab Research May Help Those Deafened By Immune System Attack

...ir cells, whose movement in response to vibrations creates the nerve signals that are fed to the brain and in... to IESCA can destroy hearing. The KHRI-3 antibody creates a staining pattern that resembles a line of tiny wine glasses when it binds to IESCA in the organs o...

Tagging pathogens with synthetic DNA 'barcodes'

...d structure. Combining several of these structures creates a web with many branching ends. "While DNA is flexible, the short strands used here are quite rigid," Luo said. "A long piece of spaghetti is floppy, but a short bit of it is quite stiff." An antibody or some other molecule that will bind to the mol...

Gene discovery sheds light on causes of rare disease, cancer

...endocytosis in order to dispose of it. As the cell creates the vesicle that will transport tagged Met, Listeria stows away and invades the cell. By manipulating the gene expression of the cells Listeria was invading, the researchers showed that specific molecules known to be involved in endocytosis w...

Hide and seek: Researchers discover a new way for infectious bacteria to enter cells

By manipulating the gene expression of the cells Listeria was invading, the researchers showed that specific molecules known to be involved in endocytosis w...

Gene therapy advance treats hemophilia in mouse models

Vector improved in two ways creates a sustained, partial correction to bleeding problems in mice A virus that typically infects insects could help with the development of gene therapy treatment for Hemophilia A, a condition in which even a bump on the knee can cause serious internal b...

Redesigned protein accelerates blood clotting

...artners with factor IX to activate factor X, which creates a burst of thrombin, which in turn generates fibrin, the sticky protein strands that form a web-like clot over damaged tissue. Calcium, a metallic element, must be present for factor VIII to work. Factor VIII has on its surface pocket-like chains of ...

Scientists find that protein controls aging by controlling insulin

...d reduced levels of it. The influence on insulin creates a problem for Klotho should it be used as a therapy against aging: It may extend life, but it could also make an animal diabetic. Mice with the excessive Klotho also had fewer offspring than normal mice, said Dr. Kuro-o, a Southwestern Medical Foun...

Study shows how retinoic acid enters a cell's nucleus

...denly looks like a classical NLS. "This discovery creates a precedent for many other proteins that don't have an NLS, and it solves a mystery that has been in the literature for a long time," Noy says. "It explains a basic mechanism of how this protein, CRABP-II, gets into the nucleus, where it can act to s...

Insects develop resistance to engineered crops

...serted into crop plants, such as maize and cotton, creates these toxins that are deadly to insects but harmless to humans. Bt crops were first commercialized in 1996, and scientists, critics and others have been concerned that widespread use of Bt crops would create conditions for insects to evolve and deve...

Enlisting genomics to understand flu evolution

...rculating viruses can exchange genes in a way that creates novel, epidemiologically significant strains--a process that can occur when someone is infected simultaneously by more than one strain. The genetic reshuffling demonstrated in this study is the first to examine in detail a reassortment event from a p...

It's electric: Cows show promise as powerplants

Improved statistical tools reveal many linked loci

... one trait," says Kruglyak. In reality, the method creates statistical conclusions that are more precise, he explains, because you're using so much data. Storey et al. compared their method to another statistical method, called two-dimensional linkage analysis, which tests for linkage between all pairs of a...
