Study warns deep-sea mining may pose serious threat to fragile marine ecosystems

...isms are at risk from seafloor mining scheduled to begin within this decade, says a new study led by a Univ...ississauga. "Imposing regulations after operations begin would prove very difficult, and some of the governments in the jurisdictions targeted by this indust...

Fast and slow -- How the spinal cord controls the speed of movement

...f the study. "Now that we know the pattern, we can begin to ask how that changes in disease states." David McLean, Cornell postdoctoral researcher in Fetcho’s laboratory, was the first person to discover the pattern of neural activation and how it was associated with speed of movement. He is the lead aut...

Get a whiff of this: Smell test could sniff out serious health problems

... says that in the near future, UC researchers will begin testing five different prototypes of the SMT built by WR Medical Electronics. Currently, Frank says an earlier model of the SMT is being tested in a high-profile clinic in Germany as well as at the University of Pennsylvania. Frank says the SMT custo...

Deconstructing brain wiring, one neuron at a time

...ys. "If you were given a wiring diagram, you could begin to understand how the chip moves electricity and how that operates the computer." Neuroscientists also want to deconstruct the flow of electrical signals in the extraordinarily complex architecture of the brain and then correlate these neural circ...

MIT's ocean model captures diversity of underwater forests

...s just the beginning," said Chisholm. "Now we can begin to ask the model questions and test hypotheses about the role of oceanic microbes in global processes. This will help guide decisions about responsible use of the oceans in this era of global change." ...

Researchers wake up viruses inside tumors to image and then destroy cancers

...ne kinase (EBV-TK), an enzyme that helps the virus begin to reproduce. This kinase is of interest because researchers know its "sister" kinase, the one produced by the herpes simplex virus, can be imaged by an injected radiolabeled chemical (FIAU), which can then be imaged using a gamma camera. "To per...

Leeches ferry infection among newts

... Further work showed that new infections generally begin at sites recently bitten by leeches, which leave behind a characteristic patch of blood under the skin. Raffel, whose work is funded by the National Science Foundation, says "when a leech sticks its proboscis into an infected newt, either the me...

Flies don't buzz about aimlessly!

...ing tight turns, and fly straight some distance to begin searching again. Scale-free movement patterns have been found in diverse animals including zooplankton, wandering albatrosses, jackals, and even human hunter-gathers. Intermittent searchers include octopi, graylings, and mating crickets. Andy Rey...

Transfusion expert urges wider use of filtered blood

...al was among the first hospitals in the country to begin using leukoreduced blood for all cardiac surgery cases. Since then, the hospital has extended its leukoreduction practice to all patients, beginning in 2000. ...

30+ AIDS vaccine clinical trials in 24 countries, research occurring on every continent

... help drive the field's R&D agenda. We hope to begin to see even more novel vectors, as well as approaches that target neutralizing antibodies in the next few years," said CEO and President of IAVI, Dr. Seth Berkley. IAVI and its collaborators are currently conducting four ongoing trials in India, ...

Gut research yields new anti-cancer approach

...han 30 percent as single agents). Tumors generally begin growing again with a year. Moving forward, the research team will seek to determine exactly which proteins are involved in the anti-cancer effect of PPARgamma inhibitors. Combination therapy is the current leading strategy in treating cancer, ...

A 'traffic light' for neurons means 'go' for improving brain research

...direct application of optical neuron control is to begin experimenting with neural circuits to determine why unhealthy ones fail and how healthy ones work. In patients with Parkinson's disease, for example, researchers have shown that electrical "deep brain stimulation" of cells can help patients, but t...

'Guardian of the genome' protein found to underlie skin tanning

...sun exposure. The spots arise when groups of cells begin producing pigment in response to repeated stress or irritation of the skin. Although not dangerous, the condition can be a cosmetic problem, depending on its location. "Our research offers a potential explanation of how this condition ?known as po...

How trees manage water in arid environments

...States, humidity is so low that water is scarce to begin with and hard to hold onto when there is a rare cl...The rapid recovery of this forest when heavy rains begin confirms the tight coupling between the trees and the available soil moisture." In short, winter ...

When your brain talks, your muscles don't always listen

...firing rate of neurons--is exerted just before you begin the upturn toward one peak and then it eases off again in the downturn toward a valley," Knight noted. Once recordings were completed at one site in the muscle, the electrode was repositioned to sample from other motor units within the muscle. ...

Anti-wrinkle compound causes pathological reaction in skin cells

...posed to it, but our results indicate it’s time to begin serious research to determine whether or not it poses a health risk." DMAE is not a unique case in the world of beauty products, continues the researcher. "Several compounds found in cosmetics are just as complex as medication—they are absorbed th...

Molecular differences between early and advanced melanomas could provide new drug targets

...leads malignant melanomas on the skin's surface to begin growing vertically beneath the skin and turn into deadly invasive cancers, scientists have found. Understanding this key molecular difference between radial melanomas that spread on the surface of the skin and melanomas that grow vertically and inva...

Vasectomy may put men at risk for type of dementia

... pushups on the bathroom floor. Other FTD patients begin shoplifting, compulsively gambling, misspending large amounts of money or become sexually demanding. The most common form of dementia caused by brain deterioration in individuals over age 65 is Alzheimer's disease. Weintraub did not find an incre...

Novel antigen-cloning technique may boost efforts to develop a melanoma vaccine

...in their work. Both the new and the old methods begin with the same steps. In order to identify and clone an antigen, researchers start with a melanoma cell or other cell of interest likely to contain relevant antigens. Based on the genes in that cell, they then make a complementary DNA (cDNA) library. ...

Scientists find potential 'off-switch' for HIV virus
