Ice core 'dipstick' indicates West Antarctic ice has thinned less than believed

...st inland from the Ross Ice Shelf. That led to the expectation that Siple Dome had to be substantially thicker than it is now as the ice moved from the mountains to the ice shelf. But the new study shows the ice could not be thick at Siple dome, so ice must have flowed toward the ocean with a very gentle slope f...

Affymetrix and the Karolinska Institutet Announce Translational Medicine Strategic Alliance

...et access to new technology at an early stage. Our expectation is that this cooperation will help us to improve peoples health", said Professor Jan Carlstedt-Duke, dean of research at Karolinska Institutet. "To improve human health, we need to shift the healthcare paradigm from diagnosing and treating existing ...

World-first Living Donor Islet Cell Transplant A Success; Procedure Offers Promise For Diabetics

...late in the blood stream after brain death." "Our expectation is that these islets from near-perfect organs will work better, although it's too early to tell," he says. The recipients use the same drugs to prevent organ rejection as are used in the Edmonton Protocol. Dr. Shapiro was invited to participate in ...

New Drugs For Bad Bugs: UF Approach Could Bolster Antibiotic Arsenal

...procedure. I think we have to come to a reasonable expectation here in terms of the balance between benefits and potential harm. The worries I have right now are because of these unrealistic expectations, the requirements are going to be even higher, and it’s going to be harder and even more expensive to bring a...

Thinking the pain away? Study shows the brain's painkillers may cause 'placebo effect'

...olateral prefrontal cortex was associated with the expectation of pain relief reported by the volunteers. In other areas, that activation was associated with relief of the intensity of pain, how unpleasant it was, or even how the individuals felt emotionally during the pain experience. Because the new study wa...

Woods Hole Research Center plans controlled burn in Amazon rainforest

...ignition in the future are all but guaranteed. The expectation is that the second fire will be hotter and more damaging than the first due to the increased volume of fuel available from those trees that perished in the first fire, and the fact that this fuel will be very dry. Center scientists are also curious t...

Virologist finds contagious equine flu in dogs

...ce of the virus jumping to humans, and there is no expectation of it doing so. It is possible the equine virus has been infecting dogs for some time, although the symptoms are very similar and could be mistaken for common "kennel cough," a bacterial disease related to pertussis (whooping cough) in children. Neve...

A New Era of Hope for the World's Most Neglected Diseases

...developed countries. Secondly, in addition to the expectation that new tools will be developed to control neglected diseases, there is a surge of interest in maximizing the effectiveness of existing tools. This interest focuses on the idea of taking the disparate vertical control programs, each targeting a spec...

Mouse study: New muscle-building agent beats all previous ones

...five weeks or more of treatment. The researchers' expectation is that blocking myostatin might help maintain critical muscle strength in people whose muscles are wasting due to diseases like muscular dystrophy or side effects from cancer treatment or AIDS. "This new inhibitor of myostatin, known as ACVR2B, is...

Melanoma vaccine strategy shows promise in laboratory experiments

...of foreign materials to the immune system, and the expectation is that dendritic cells presenting the BRAFV600E peptide would trigger the killer T cells even more effectively than the monocyte cells used in the current study. Indeed, such prepared dendritic cells might serve as the basis for a treatment vaccine ...

Confidence in memory performance helps older adults remember

...adaptive strategies for remembering often have the expectation that there is nothing they can do to improve memory. The study's results suggest that interventions that target conceptions of control over memory could be effective for improving strategy use and enhancing memory in middle and later adulthood. ...

Scientist-astronaut sends T-cells into space

...o, Hughes-Fulford will analyze the results. "Our expectation is that the T-cells in the centrifuge ?basically, under artificial gravity ?will be activated normally, and the T-cells in microgravity will not be activated," she predicts. "We will compare them side by side and discover, for the first time, exactly...

Brain's 'gambling circuitry' identified

...gions that specifically responded to either reward expectation or risk. Importantly, these areas showed activity that increased with the level of expected reward and perceived risk. The researchers found that the activation related to expected reward was immediate, while the activation related to risk was delaye...

Pleasure and pain: Study shows brain's 'pleasure chemical' is involved in response to pain too

...a needle inserted into a large jaw muscle, and the expectation of pain and repeated questioning. Similarly, dopamine release in two other areas of the basal ganglia ?the putamen and caudate nucleus ?was strongly correlated with the rating of how intense and unpleasant the pain itself was on a scale of 0 to 1...

Anticipation plays a powerful role in human memory, brain study finds

...boratory for Brain Imaging and Behavior. "Just the expectation of seeing something bad can enhance the memory of it after it happens." A teacher who struggles with stage fright, for example, might feel anxious before every class she has to teach. The UW-Madison work suggests that the longer she spends dreading...

Mitochondrial genes move to the nucleus -- but it's not for the sex

...ng. Brandvain said the finding contradicts the expectation that mitochondrial genes migrate to the nucleus because of the evolutionary benefits conferred by sexual recombination. "The benefits of sex could have driven the transfer," he said. "There are powerful arguments out there for that. But that's just n...

Carnegie Mellon University research shows how sensory-deprived brain compensates

...ry is made to use a poorly performing arm with the expectation that the brain may be plastic enough to assist that arm in recovering motion. "We think that our well-designed model is extremely good for future in-depth studies of brain plasticity in response to changes in how an animal senses its environm...
