A rice future for Asia

...sian way of life for generations. Few rice farmers want their children to be rice farmers, and even fewer ...ide a brighter future for rice in the region. "We want them to understand that rice research is not some sleepy little scientific backwater, but is, in fac...

Robots manipulating animal behaviour

...even colonies of robots." Asked why people would want to influence animal behaviour, Deneubourg offers several answers. Firstly, by changing the way animals behave or inducing collective behaviour, scientists can learn much about animal communications and information processing. Secondly, the ability to...

Nanotubes used for first time to send signals to nerve cells

...alized nanotubes we tested," Pappas said. "Next we want to find a way to functionalize the nanotubes to ma...rd ongoing electrical activity in cells. "Where we want to get to is a device that can both sense and deliver stimuli to cells for things like prosthetic co...

Just like us, social stress prompts hamsters to overeat, gain weight

... as a model for human stress-induced obesity. They want to begin unraveling the complex factors that lead ...compared to corticosterone. Researchers will also want to know if drugs can block stress-induced obesity, for example, by blocking the release of the stres...

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

... variety of environmental settings," Ham said. "We want them to be comparatively cheap to build and operate. They'll provide a data-collection tool that offers tremendous flexibility to users. We're really developing a new tool for researchers that will allow them to go out and comprehensively map the veg...

Salk scientists get to the root of plant cell fate

...at give rise to leaves, branches, and flowers. "We want to know how a plant can set aside a root and a shoot pole during embryogenesis and keep these functions separate," Long says. The researchers found that the TOPLESS gene encodes a protein (TOPLESS) that is a transcriptional co-repressor. In plants a...

Bone marrow may restore cells lost in vision diseases

...easons why the disease is occurring." Researchers want to discover ways to mobilize an elderly patient's own cells to travel to the injury site to make repairs. "The dogma has been that we're born with a fixed amount of RPE, but there is growing evidence retinal progenitor cells exist in the adult," sai...

Immune system police learn early and sometimes badly

...w they are being generated is still a question. We want to look into the nature of antigens those receptors recognize which will allow us to predict more how they are being developed in the thymus." ...

New research promising for improving brain cell survival after brain injury

...the same thing," Prof Tan said. "Ultimately, we want to deliver the drug to patients suffering brain injury from stroke or trauma so save as many neurons as possible. "Such a drug would limit damage to the brain after the injury, as well as the subsequent few days when injured nerves release 'suicid...

Meth promotes spread of virus in HIV-infected users

...V-infected subjects. That is the next question we want to answer. "Since meth mediates its effects through interacting with dopamine receptors present on the cells, and meth increases DC-SIGN, which are the HIV attachment receptors, use of dopamine receptor blockers during HIV infection in meth user...

Researcher gives hard thoughts on soft inheritance

...puts us on a slippery slope that many people don't want to visit," Richards says. Nutritional epigenomics Still, recent studies in mice and rats have fueled the controversy. Richards cited "a whole new world called nutritional epigenomics," where researchers are trying to influence ep...

UCSD researchers develop 'smart petri dish'

...s introduced to the body. Pharmaceutical companies want to know early on the effect a drug has on the liver. But it's very expensive to screen every potential candidate on living animals, typically rats. So if you can use just a few cells from the liver rather than the entire animal, you can perform many...

Arctic expedition will investigate alien-like glacier

...in a cold and sulfur-rich environment. "We really want to try and understand the plumbing system for this spring and where all this sulfur is coming from," Beauchamp said. "This is a very unusual feature on the earth's surface and it's an extreme ecosystem that could be a good model for how life first be...

Tumor wizardry wards off attacks from the immune system

...ee these findings advance cancer immunotherapy. We want to find a way to actively suppress T-reg cells and at the same time actively evoke an immune response to tumor-specific antigens." In collaboration with other researchers at the School of Medicine, Linehan is planning to set up a clinical trial tha...

Beekeepers work hard for the honey, despite changing tupelo forest

...e public knows how hard it is to produce honey. We want more awareness of the social context of beekeeping and how environmental change and sociopolitical and economic factors play out to influence the use and access to tupelo forest." Some beekeepers say that every year they seem to be getting less hon...

Genetic snooze button governs timing of spring flowers

...re are many crops - cabbage, beets - that we don't want to flower. Many of the cultivated varieties we use are never exposed to cold in a typical farmer's field growing season." When that is the case, a cold snap can fool sugar beets, for example, into flowering, a process that can ruin the crop by redi...
