Penn researchers study the use of ultrasound for treatment of cancer

... results are extremely encouraging. They raise the possibility that, in the future, treatments with ultrasound either alone or with chemotherapeutic and antivascular agents could be used to treat cancers." ...

Scientists crack code for motor neuron wiring

...ity to muscle targets. The studies also raise the possibility that the combinatorial code contains additional information, beyond the regulation of motor neuron wiring. "This is still conjecture, but the sheer number of Hox proteins, and their capacity to direct neuronal differentiation, suggests that they may ...

ASU researchers 'wire' DNA to identify mutations

...y of Sciences, demonstrate for the first time, the possibility of directly identifying these mutations, or single nucleotide polymorphisms (SNPs), by means of measuring the electrical conductance of a single DNA molecule. SNPs are buried in the 3 billion DNA bases of the human genome. On average, SNPs occur ...

Have a taste for fat? Yes! A sensor in the mouth promotes preference for fatty foods

...sweet, salt, sour, bitter, and umami stimuli. The possibility for an additional taste modality directed to lipid has often been suggested because many animals exhibit a spontaneous attraction for fats, but the existence of an actual sensor remained a matter of debate. In a paper appearing in the November 1 is...

Researchers uncover mechanisms of estrogen in promoting cell death in breast cancer

...east cancer cells or tumors. The results raise the possibility that estrogen therapy may overcome resistance to certain breast cancer hormonal therapies. The study appears in the December 7 issue of the Journal of the National Cancer Institute. When cancer treatments such as chemotherapy or hormonal thera...

Alleged 40,000-year-old human footprints in Mexico much, much older than thought

...t was deposited. This makes extremely unlikely the possibility that the original ash had been weathered into sand...earchers wrote in their paper, "we consider such a possibility to be extremely remote." Many paleontologists have withheld judgment on the alleged footprints, awa...

Source of crucial immune cell in the skin discovered

...to new therapies to help children who now face the possibility of lifelong complications. "It is known that Csf-1 levels are elevated in patients with Langerhans histocytosis," said Dr. Merad. "Our findings indicated that finding ways to lower Csf-1 levels may produce new therapeutics for these patients." ...

New evidence questions the simple link between prion proteins and madcow disease

...digestion resistant PrP molecules is unlikely. The possibility of there being infectious molecules other than PrP must therefore be seriously considered," says Jeffrey. "A lot of people are completely wedded to the prion hypothesis of diseases like vCJD, but the more you deal with whole animals as opposed to re...

Newly identified mechanism helps explain why people of African descent are more vulnerable to TB

...e to TB infection. It is exciting to consider the possibility that innate immunity to tuberculosis and other infections in vulnerable populations might be enhanced by providing a simple vitamin that would cost only pennies a day." ...

Microbes convert 'Styrofoam? into biodegradable plastic

...r. The study is among the first to investigate the possibility of converting a petroleum-based plastic waste into a reusable biodegradable form. O’Connor and his colleagues from Ireland and Germany, utilized pyrolysis, a process that transforms materials by heating them in the absence of oxygen, to convert poly...

UW scientists unravel critical genetic puzzle for flu virus replication

..." What's more, scientists have been exploring the possibility of using strains of influenza to ferry genes from one virus to another to speed and optimize vaccine production. More efficient methods of vaccine production will be critical should a global outbreak such as the "Spanish " flu pandemic of 1918 recur....

Invasive species harms native hardwoods by killing soil fungus

... remain poorly understood," Stinson adds, "but one possibility is that invasive species may disrupt fragile ecological relationships that evolved over millions of years." Stinson and her colleagues found that garlic mustard targets arbuscular mycorrhizal fungi (AMF), which form mutually beneficial relationships...

There's something fishy about human brain evolution

... a larger brain," argues Dr. Cunnane. "The genetic possibility was there, but it remained silent until it was catalyzed by this shore-based diet." Dr. Cunnane acknowledges that for the past 20 years he's been swimming upstream when it comes to convincing anthropologists of his position, especially that initial ...

U of MN researchers identify ataxia gene

... his uncoordinated and uneven gait, suggesting the possibility that he showed early features of the disease. Ranum started this historical and scientific journey more than a decade ago. She and her colleagues John Day, M.D., Ph.D., University of Minnesota, and Larry Schut, M.D., CentraCare Clinic in St. Clo...

Successful cell engineering may lead to mad cow prevention, say researchers

...nal Academy of Sciences. Their success raises the possibility of introducing the same technology into cattle to prevent numerous diseases. "The exciting part is that we may be able to use this technology to prevent other diseases from ever starting," Westhusin explains. "We were able to knock down the ...

Attention shoppers: Researchers find neurons that encode the value of different goods

... make choices," says Padoa-Schioppa. "A concrete possibility is that various choice deficits may result from an impaired or dysfunctional activity of this population, though this hypothesis remains to be tested." In his experiment, Padoa-Schioppa had macaque monkeys choose between two types of juice offered ...

Defective immune system response to smallpox vaccine detailed in new study

...nce the early 1970s. But recent concerns about the possibility of a bioterrorist attack using smallpox virus prompted authorities to reinstate voluntary smallpox vaccination for specific groups, such as military personnel. In the first five months of 2003, the U.S. Department of Defense vaccinated more than 450,...

Darkness unveils vital metabolic fuel switch between sugar and fat

...at," the authors conclude, raising the longer-term possibility of 5'-AMP-based therapies for obesity or type 2 diabetes. ...

Born with a love of speech

... to hear a range of frequencies. Thus, there's the possibility that newborns preferentially listen to speech because they're used to it from their in-utero tuning-in. But, which speech sounds actually get through the uterine sound barrier to the fetus? According to Dr. Vouloumanos, the best evidence indicates t...

Stanford study of owls finds link in brain between sight and sound

...the mechanisms of attention naturally leads to the possibility of applying their knowledge to human disorders of attention, learning and schizophrenia. "If you understand mechanistically how something works, then you will know how best to fix it," said Knudsen. "It's like with a car; if you know in detail how it...
