Discovery in orange cauliflower may lead to more nutritious crops

...content in staple crops." Other researchers have created "golden rice" by inserting several genes that increases the synthesis of beta-carotene. But this technique has proved less effective in many plants. Li's research, which increases a plant's ability to store beta-carotene, may offer an alternate and c...

Modeling the restless brain

... the human brain are connected. The computer model created by Sporns and Honey suggests that this very pattern of connectivity is crucial to generating and shaping brain activity in the resting and active brain. Empirical work on the human brain is challenging due to the fact that the brain's intricacies...

Alzheimer's disease to quadruple worldwide by 2050

... prevalence of Alzheimer’s disease, the researcher created a multi-state mathematical computer model using United Nations population projections and other data on the incidence and mortality of Alzheimer’s. ...

Newly discovered antibody may be body's natural defense against Alzheimer's

...ersity of California at Irvine, who had previously created anti-oligomer antibodies in rabbits. Using techniques pioneered by Dr. Glabe's group, the NewYork-Presbyterian/Weill Cornell scientists were able to measure and extract the human version of anti-oligomer antibodies from IVIG and then demonstrate that...

Plastic that grows on trees

...ck. In fact, attempts at direct glucose conversion created so many impurities that it was simpler to start with the fructose, less common in nature than glucose. Zhang and his team, working with a high-throughput reactor capable of testing 96 metal halide catalysts at various temperatures, discovered that...

UCF nanoparticle offers promise for treating glaucoma

... now used in most eye drops. Seal and his team created a specialized cerium oxide nanoparticle and bound it with a compound that has been shown to block the activity of an enzyme (hCAII) believed to play a central role in causing glaucoma. The disease involves abnormally high pressure of the fluid ins...

Researchers demonstrate way to control tree height

...id in their report. Dwarf trees and crop plants created with traditional cross-breeding or horticultural t...ution,” in which plants such as rice or wheat were created that directed less energy to height growth and more to development of stout stems and plentiful seed...

AAAS decries latest stem cell veto

...ing to fewer than 20 stem cell lines that had been created when the president first announced U.S. policy in 2001. "Our concern is that this action has the potential to delay development of important new therapies by cutting off a promising avenue of research," said Alan I. Leshner, the chief executive of...

New vaccine prevents CMV infection and disease in mice

...s. “Using a two-pronged approach, we successfully created and tested a vaccine in a mouse model with CMV that shows enormous promise for re-directing the body’s immune system, enabling it to fight the virus.” The mouse vaccine generates an immune response that protects against both infection and developm...

New research shows sharks use their noses and bodies to locate smells

...rogram (BUMP) Masters student and study co-author, created two parallel, turbulent odor plumes – one using squid scent and the other a plain seawater control. Minimally turbulent ‘oozing’ sources of squid odor and seawater control were physically separated from sources of major turbulence by placing a brick ...

How brain pacemakers erase diseased messages

...ion works a challenge, Grill said. Grill's team created a mathematical model of a normally functioning brain cell. The researchers then gave the model neuron the pathological pattern of activity seen in people with tremors, assembled a group of these model cells and watched what would happen when the cell...

Machine preservation may promote more organ sharing

...xpanded criteria" donors (ECDs). This category was created by UNOS in 2002 so that higher risk donor organs, once considered unsuitable, could be transplanted safely. The category includes kidneys from deceased donors over age 60 years or those over age 50 with health conditions such as high blood pressure, ...

New knowledge improves rice quality

...ch and Asia’s continuing economic development have created important new opportunities. "These are the two key changes driving the whole process and making this research area so exciting," Dr. Zeigler said. "If we can link these two things together ?our new and improved knowledge and understanding of rice...

Diminishing dinosaur steps saved by laser and laptop

...- but a permanent and detailed record has now been created using cutting-edge equipment. Using a high-tech...ble site. The computer-generated trackways we have created preserve important information on the locomotion of dinosaurs, which can be properly accessed for th...

Magnetic computer sensors may help study biomolecules

...in valves are turned on, a local magnetic field is created that is strongest near the ends of the magnetic stack below the membrane—a field strong enough to trap nanoscale magnetic particles. The NIST experiments demonstrated that the spin valves not only can trap magnetic particles, but also can be used ...

DOE JGI sets 'gold standard' for metagenomic data analysis

...e assembly tool Phrap, they actually saw artifacts created by the program caused by mixing sequences that should not have been mixed. "It's like when you're in the market for a digital camera, you can go to web sites like CNET to see the reviews, make the comparisons, and get some guidance for choosing t...

DNA-damage test could aid drug development

...st. Additionally, he experimented with mutant mice created by Samson's lab that are deficient in certain DNA-repair systems. The bone marrow cells derived from these mice, and the cells cultured from that bone marrow, proved more sensitive to the toxic agents than were the cultured cells from normal mice, fu...

Dinosaur hearing, listening to muscle noise, quieter cubicles

...es, "it has much to tell us about the culture that created it." (2pAAb1) REHABILITATING THE WORLD'S WORST SOUNDS Something that is very 21st century is the ability to gradually morph, or transform sounds from one to another. A variation of morphing is to transfer the features of one sound, say a ca...

Researchers develop way to calculate speed of bacterial sex

... processes in an isolated environment, researchers created a new mathematical model of bacterial transport and conjugation that focused on subsurface bacteria colonizing surfaces, such as sand and soil grains. The UC-Davis research was funded by the National Science Foundation. The new model was then used...

First demonstration of new hair follicle generation in an animal model
