Research identifies protein that signals flowering in squash plants

...etative under LD conditions and flowered only when grown under SD conditions. The authors then used the potyvirus Zucchini yellow mosaic virus (ZYMV) as a delivery vector to test whether long-distance movement of FT mRNA and/or FT protein was required for floral induction. The choice of a potyvirus vect...

CSIRO scientists join fight to save 'Tassie devil'

...ected animals where both tumour tissue and tumours grown in the laboratory were examined. A recent Senior Scientist’s Scientific Forum on the DFTD reviewed progress in understanding and managing the disease and set an agenda for future research and management. “The aim is to stop the disease in it ...

Pesticides choke pathway for nature to produce nitrogen for crops

...t, in turn, benefit primary market crops like corn grown after legume rotations. __IMAGE_2 Legume plants secrete chemical signals that recruit the friendly bacteria, which work with the plants to convert atmospheric nitrogen into ammonia that, then, is used as fertilizer by the plants. "Agrichemic...

Potent possibilities for parasite attack

...e the properties of the parasite cell surface have grown in number and some declined among the three species: 'death' of genes seems to be a major force for differences between the parasite genomes. Some genes, however, are evolving rapidly, leading the team to suspect they include key genes involved in in...

Researchers demonstrate way to control tree height

...ecreased signaling by gibberellic acids. They were grown in the field with USDA approval, and assessed several times for variation in size and appearance. Other than reduced size, there appeared to be striking variation in foliage color and leaf shape, some of which might have significant ornamental val...

Salk scientists hammer out a pathway that promotes muscle cell survival in mice

... researchers reduced SIK1 activity in muscle cells grown in the lab using a technique that silences gene expression. Less SIK1 activity resulted in less phosphorylated HDAC. With the unphosphorylated HDAC brake now firmly in place, expression of muscle-specific target genes was also reduced. Conversely, wh...

A cherry on top: Tart cherries may alter heart/diabetes factors

...n. The cherries were Montmorency tart cherries grown in northern Michigan, frozen, and powdered. Michigan is the nation's largest producer of tart cherries, which are used in pies and jams as well as juice. They are different from the sweet Bing cherries that are often eaten raw, and have higher concen...

pHLIP, a novel technology to locate and treat tumors

...bloodstream and accumulated in mouse breast tumors grown to different “stages?on the leg of a mouse. The researchers demonstrated that by attaching fluorescent probes to a pHLIP peptide, tumors could be detected. They expect that by attaching and delivering active agents with pHLIP, that tumors may be a...

The longest carbon nanotubes you've ever seen

...ufacturing for certain materials, researchers have grown carbon nanotubes that are the longest in the world. While still slightly less than 2 centimeters long, each nanotube is 900,000 times longer than its diameter. The fibers--which have the potential to be longer, stronger and better conductors of elec...

Tissue engineered scaffolding allows reproduction of cartilage tissue

Scientists develope a new model of artificial canine skin

...d as a support for the epidermis cells, which were grown on its surface and were kept in growth conditions exposed to air. The cells proliferated forming the various layers of the epidermis. The model develops a morphological structure similar to that of canine skin. Additionally, the expression of the ...

Thymus transplants gives hope to babies with fatal immune disease

... access to the heart. The removed thymus tissue is grown in culture for several weeks in a laboratory while researchers ensure that there are no diseases present in the tissue. Strips of tissue are then implanted in the baby's thigh, where they attract a blood supply and begin to act like a thymus gland. W...

Scientists seek useful traits in wild cottons

...eriment Station research assistant, screens cotton grown hydroponically ?without soil ?for salt tolerance. ... Station research assistant, are screening cottons grown at Lubbock for thrips and Lygus bug resistance. "Thrips are a serious cotton pest," Arnold ...

Growing nerve cells in 3-D dramatically affects gene expression

... new Brown University study shows that nerve cells grown in three-dimensional cultures use 1,766 genes differently compared to nerve cells grown in standard two-dimensional petri dishes. The study, published in the May issue of Tissue Engine...

Leukemia drug turns mini-molecules up, cancer genes down

...In this study, the researchers used leukemia cells grown in the laboratory and cells donated by patients to study how the drug ATRA affects miRNA levels and how those changes affect the cells. The investigators exposed the leukemia cells to the drug for up to 96 hours, causing the cells to mature. The ...

MIT's ocean model captures diversity of underwater forests

...ts of diverse microscopic plants they "sowed" have grown in population patterns that precisely mimic their real-world counterparts. This model of the ocean is the first to reflect the vast diversity of the invisible forests living in our oceans-tiny, single-celled green plants that dominate the ocean and ...

Need oxygen? Cells know how to spend and save

...ally present in normal room air) compared to cells grown in hypoxia. In low oxygen, liver, uterus, lung and colon cells all made COX4-2. The researchers then exposed mice to hypoxia for a few weeks and found that they too showed increased levels of COX4-2. In 1992, Semenza's team had discovered a prote...

New report: Explosive growth changes salmon industry

...n industry in the last 25 years: farmed salmon has grown from just two percent of the world supply in 1980 to 65 percent in 2004. About three-fourths of the fresh and frozen salmon consumed in the United States is now farmed. In response, the value of the North American wild fishery has plummeted, as ind...

Researchers identify ovarian cancer biomarkers

...cent of patients are diagnosed after the tumor has grown large or spread. There are few or no symptoms early in the disease and no effective screening tests. Early diagnosis is crucial, marking the difference between a 95 percent survival rate for cancers found at the earliest stage and 20 percent survival...

Bypassing eggs, flu vaccine grown in insect cells shows promise
