Researchers test new therapy for advanced melanoma

...ne therapy gives us the flexibility to introduce a huge variety of potential targets for treatment, but its major limitation has been getting the gene into the cancer. If electroporation can deliver the gene to these tumors reliably and without serious side effects, melanoma and other cancers would be ope...

Scientists find viruses can't stick to sea bugs in the dark

...s algae can cause massive, toxic blooms, poisoning huge areas of the sea with their waste products and killing fish, sea mammals such as whales, dolphins and seals, and even humans. Control of these blooms is vital to the health of the seas. "Research using cyanophages to control blooms of cyanobacteria ...

NASA probe could reveal comet life, scientists claim

...ing. The comet will remain intact despite losing a huge amount of material ?100,000 tonnes from a 100 metre diameter crater, and the impact is not expected to alter the comet's orbit. "Not only is Deep Impact a spectacular experiment, it is also a test for our long-standing arguments," added Professor Wi...

High fidelity keeps human DNA assembly line humming

...earchers consider control of RNA synthesis to be a huge issue in human health. It is also the foundation of how living systems function. In the world of molecular biology, much attention has been given to how RNA is made. Burton explains that it is similar to an industrial assembly line, with DNA being a...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

...to 5,500 meters below surface, research that holds huge promise for biologists. Says Dr. Ron O'Dor, Chief Scientist of the Census: "DNA research made possible through this project may allow us to reconstruct the history of marine evolution." More than scientific curiosity drives this enterprise. The pla...

MicroRNAs play a big part in gene regulation - and evolution

...to the importance and function of microRNAs across huge evolutionary time scales, suggesting that some microRNAs could be involved in shaping the diversity of life," says lead author Nikolaus Rajewsky. The information will be a vital tool for the microRNA research community, providing opportunities to te...

Mechanism for the captation of nutrients in plants- unknown to date

...vesicles. Subsequently, the cell starts to capture huge quantities of saccharose through endocitosis. The results of the research has shown, moreover, that only saccharose is capable of initiating endocitosis, given that, in the trials undertaken with substances similar to saccharose, such as glucose or ...

It's electric: Cows show promise as powerplants

...could use their farm's livestock waste lagoon as a huge fuel cell and generate enough power for their operation," Rismani-Yazdi said. ...

Motor transport in bio-nano systems

...3132, May 2005). Each cell of our body contains a huge number of small vesicles which exhibit complex patterns of intracellular traffic: some vesicles travel from the cell center to the periphery and vice versa, some shuttle between different organelles or cellular compartments. An extreme case is provid...

Improving the potential of cancer vaccines

...cancer can get underway quickly. "It could have a huge impact on cancer therapy or treatment of infectious disease," said Wang. "It could boost response to cancer vaccine as well." ...

Researchers feed tiny pills of RNA to planarians to identify genes essential for regeneration

...stasis must exist," Sánchez Alvarado said. "It's a huge step forward for us and opens the possibility of systematic molecular studies to find the genetic cause of regenerative processes in animals." Silencing planarian genes may also help in studying human disease. Thirty-eight of the genes Sánchez Alvar...

VCU study shows hormone-like molecule kills cells that cause inflammation in allergic disease

...hey go, what they do, and when they die can have a huge impact on health and disease. "For example, there has been one report of a patient with mastocytosis, which is a type of pre-leukemia where mast cells proliferate abnormally, that showed improvement with IFNγ treatment," he said. "It is possib...

Promiscuous Catalytic Activity Possessed by Novel Enzyme Structure

...alled a prenyl group. That modification can have a huge impact on where the aromatic molecule goes within the cell, and what sort of effects it has when it reaches its target. “When you make that so-called hybrid molecule, all the chemistry associated with the original compound changes,?said Noel. He exp...

Oxygen increase caused mammals to triumph, researchers say

... very large - mammals like 12-foot-tall sloths and huge saber-toothed cats. They paved the way for all subsequent large mammals, including ourselves." The results described in Falkowski's article, "The Rise of Oxygen Over the Past 205 Million Years and the Evolution of Large Placental Mammals," stem from...

Study shows eutrophic lakes may not recover for a millennium

... of the watershed where it is applied. "There's a huge amount of phosphorus in the watershed that hasn't washed into the lake yet," says Carpenter, meaning the problem is likely to persist for centuries. The new study models phosphorus loading into Lake Mendota, an urban lake in Madison, Wis., that stil...

Beauty queens urge girls not to sacrifice their bones

..., Thailand remarked that osteoporosis is already a huge health problem in Asia, and getting more serious every day- in 45 years (by 2050), one out of every two fractures in the world will occur in Asia. All women and men should take immediate action to review their life styles and take the IOF One Minute...

Primate virus jumps species barrier to humans for first time in Asia

...not been much work on the topic in Asia, which has huge primate diversity and large human populations." Jones-Engel and her co-authors also argue for more research on diverse contexts of human-primate contact. The vast majority of previous viral transmission research focused on bushmeat hunting and consu...

Microbe has huge role in ocean life, carbon cycle
