Good times ahead for dinosaur hunters, according to U of Penn scientist's dinosaur census

... of all dinosaur genera that existed did not leave behind fossils that could be found. "I would never suggest that this prediction, however statistically sound, is the final word on dinosaur diversity," Dodson said. "My intention is to fuel the discussion using the facts at hand, and this is the best estim...

New gene linked to bipolar disorder

...ls will help us to fully understand the mechanisms behind this gene and explore how we might be able to intervene in these mechanisms, to help people with the disorder. "We hope our discovery will eventually lead to new treatments for depression and bipolar disorder, including possible preventive strateg...

Math model predicts cancer behavior

...te a harsh microenvironment in the tumor may leave behind the most aggressive and invasive tumor cells. "In the immediate term we may be diminishing tumor burden, but the long term effect is to have a much nastier tumor than there was to begin with," Quaranta said. There is anecdotal evidence, he added, t...

New study aims to stop sepsis in its tracks

...venous fluids does the team realize it is suddenly behind the eight ball. By then, the patient is quickly spiraling into multisystem organ failure. Starting resuscitation at this point may already be too late." To test ways of managing the disease during the first six hours after diagnosis, the consortium...

Single molecule extends fat mice lives by reversing gene pathways associated with disease in obese

Common cold virus may kill breast cancer cells

...t on the disease. The NBCF has thrown its weight behind a National Action Plan for Breast Cancer Research and Funding, developing sustainable research collaborations, which could halve the time it will take to answer the big questions in breast cancer. National Breast Cancer Foundation CEO Ms Sue Murray...

Cholera pathogen reveals how bacteria generate energy to live

...tists add key specifics to the molecular mechanism behind the pathogen that causes cholera. The work could provide a better understanding of this pathogen, while also offering insight into how cells transform energy from the environment into the forms required to sustain life. As a single-cell organism, Vi...

CSIRO imagery shows Outer Great Barrier Reef at risk from river plumes

...an events in real-time, building on the technology behind the successful SENTINEL bushfire tracking system. While extreme coastal events have been captured by remote sensing before, this is the first time they can be seen and analysed straight after the event as there are now more satellites imaging the...

Syphilis rate on rise in US gay, bisexual men

Magnetic system could be key to surgery without scars

... surgery requires four or five holes. The question behind this is, can we do the surgery through only one hole and can we hide the hole in a cosmetically advantageous or less painful location,?Dr. Cadeddu said. Study researchers concluded that “the ability to reduce the number of trocars (holes) necessar...

Thinking with the spinal cord?

...the current issue of Science. The research group behind the surprising results consists of Professor Jørn Hounsgaard and Post.doc Rune W. Berg from the University of Copenhagen, and Assistant Professor and PhD Aidas Alaburda from the University of Vilnius. The group has shown that spinal neurons, during n...

Biologically inspired sensors can augment sonar, vision system in submarines

...ect the hydrodynamic wake (such as the wake formed behind a propeller-driven submarine) for long-distance tracking. With further advances in engineering, man-made underwater vehicles should be able to autonomously image hydrodynamic events from their surroundings, Liu said. "Although biology remains far s...

Ultrasound upgrade produces images that work like 3-D movies

...nto one, gaining a 3-D effect. This principle lies behind 3-D movies and the familiar Fisher Price View-Master toy. With practice, some people can "defocus" their eyes and fuse the paired images without the aid of any special viewing device. (Find out how at http://en.wikipedia.org/wiki/Stereoscopy .) T...

Gene hunters close in on Lou Gehrig’s disease

...le is at risk of developing the disease. Genes behind inherited forms of ALS -- responsible for about only 5 percent of all cases -- were discovered a decade ago, but no genetic roots have previously been found for sporadic ALS, which occurs in people without a family history of the disease. In the J...

Researchers hot on the trail of brain cell degeneration

The researchers behind the study hope that the results can be used in planning new targets for drugs to reduce the cell destruction signals caused by calcium entry. Finding new targets for medicine development is also significant in terms of the economy, owing to the costl...

Inflammation may play role in metastasis of prostate cancer

...oduced by inflammatory cells are the 'smoking gun' behind prostate cancer metastasis. The next step is to completely indict one of them." One in six men will be diagnosed with prostate cancer, and one in 33 will die of metastatic disease. Early tumors confined to the prostate can be treated, but no effe...

Growth hormone is not the anti-aging bullet for healthy adults

...u said. "We wanted to see if there is any validity behind some of the claims made about growth hormone's anti-aging properties. "Our biggest surprise was the general lack of research that had been done in this area. When we reviewed the scientific evidence, we found that there were really only about 500...
