Quantum Dots Research Leads to New Knowledge about Protein Binding in Plants

...ver a way toutilize Quantum Dot bio-conjugates to uncover new knowledge about the binding of a protein at the growingpollen tube tip. This protein plays a critical role along with anotherprotein (chemocyanin) in guiding sperm-laden pollen tubes to the eggsfound in ovules. Applyingnanoparticles for imaging ...

Research on Worms Yields Clues on Aging

...orms' lives by 47 percent.The group then sought to uncover the underlying mechanism for theeffect of the anticonvulsants. It was apparent that the drugs did notmimic the anti-aging effects of caloric restriction, because the wormshad abundant food and looked well-fed. The researchers alsodemonstrated that an...

Spider Venom Could Yield Eco-Friendly Insecticides

.... As researchers inventory more kinds of venom and uncover insecticide leads, they may be able to target insects that transmit new and emerging human diseases, such as Lyme disease and Rocky Mountain spotted fever (ticks) and dengue and yellow fever (mosquitoes). "One could envision specifically targeting m...

Computational Method Speeds Mapping of Cell Signaling Networks

...quires no prior knowledge of signaling pathways to uncover molecular relationships. This is a distinct advantage according to Pe'er, who notes, "Unlike classical biochemical approaches where you need to know all of the intermediate players in a network, this system can detect indirect influences" between mol...

Researchers uncover sequence of major rice pathogen

... and their production. "The primary mission is to uncover the organism's weaknesses. You do that by building up an arsenal of information of what genes are involved in plant-pathogen interactions," Dean says. In July 2002, Dean and researchers from the Whitehead Institute at MIT, now called the Broad Insti...

Different microarray systems more alike than previously thought

...e these systems may ultimately allow scientists to uncover critical differences between, say, healthy and cancerous tissue. Unless laboratories can rely on each others' results, such findings would not have much value. For the study, 10 laboratories in the Washington, D.C./Baltimore area were given identica...

Designing vaccines by computer

...tics and computer modelling can help scientists to uncover and harness the hidden patterns in the wealth of DNA and protein sequences that modern bioscience generates and cut the number of compounds drug companies need to test when searching for new vaccines. Researchers funded by the Biotechnology and Biol...

Thai spice helps cut blood sugar swings

...has an effect in rats, the next step is to try and uncover its mechanism. He said that "if we can reduce the peaks and valleys of insulin with HCA, then it might have some application in diabetes, both in slowing progression to diabetes 2 and since these people have an obesity problem, it could potentially h...

15-year hunt finds cause of pseudothalidomide syndrome

...s, they've worked with us quite closely to help us uncover the gene behind the syndrome," says Gordillo. "Now we have about 10 affected families from outside Bogotá, and we can offer a genetic test to families at risk of Roberts syndrome." Vega and Gordillo, a husband-and-wife team, criss-crossed the globe ...

Experiment station researchers to explore genome of disease-fighting fungus

...es. Researchers say the genome sequencing work may uncover chemical compounds and beneficial genes useful in producing new human and animal antibiotics. The sequencing project is a collaborative effort with the Department of Energy Joint Genome Institute. Experiment Station plant pathologists are Drs. Charl...

High-powered gene profiles provide clues to genes involved in common form of lung cancer

...art of a renewed effort by scientists worldwide to uncover the basic biology of lung cancer, the number one cause of cancer-related deaths in the United States. Non-small cell lung cancer (NSCLC) accounts for about 75 percent of all lung cancers and is responsible for nearly 120,000 deaths in this country an...

Bioinformatics reveals new gene regulation system

...d Gelfand. Using multiple bioinformatics tools can uncover cell systems that might have escaped experimental detection, he suggested. "By comparing hundreds of genomes, you can see patterns that are not seen when looking at just a couple of them." ...

Researchers find first evidence of venom system in extinct mammal

...lberta is one of the richest areas of the world to uncover the types of fossils that we're interested in." ...

How monarch butterflies are wired for navigation

...have explored the infinitesimal butterfly brain to uncover new insights into that machinery. Their findings show that the same ultraviolet light that has become an anathema to cancer-wary humans is critical for butterfly navigation. Also, the researchers were surprised to discover a key wiring connection bet...

New vaccine protects more effectively against tuberculosis

Max Planck researchers uncover the mechanism by which the new genetically engineered vaccine functionsThe vaccine has been licensed to the Vakzine Projekt Management who will test it in clinical trials early 2006. The responsible mechanisms for the high efficacy of this vaccine ha...

TGen awarded $7.1 million to accelerate brain disease research

...uding victory in the Tour de France, and you might uncover some incredibly important, indeed amazing facts about what training and dedication can accomplish. What Edward F. Coyle of the University of Texas-Austin found out about Lance Armstrong was that from 1992-1999, the year of his first of now six conse...

MSU researchers receive $4 million grant to uncover gene functions

...lion grant from the National Science Foundation to uncover the functions of genes in a plant - research which may ultimately lead to improvements in human health and agriculture. In a collaborative effort spanning several departments, MSU scientists will determine the functions of roughly 4,400 nuclear gene...

Hopkins scientists uncover 'tags' that force proteins to cell surface

...ts or ways to help people who can't smell, or help uncover new strategies for treating CF. Although many scientists would say that failure to get these proteins to the cell surface means the proteins weren't assembled properly in the cell, Li says that how and where proteins are made has a lot to do with t...

Whisky fans can drink to crop research

...h Council (BBSRC) are beginning a new programme to uncover key genes that control the specific characteristics of different barley varieties. The research, being carried out at the Scottish Crop Research Institute, Birmingham University and NIAB, involves almost all barley breeders in the UK and associated ...
