23/08/2016Combining ultrasound energy and microbubbles to poke holes in cells may prove to be a new tool in the fight against cardiovascular disease and cancer, according to researchers from the University of Pittsburgh and UPMC. A study on this gene therapy approach, called sonoporation, is published in the Proceedings of the National Academy of Sciences (PNAS).
18/08/2016Mathematicians are now developing completely new statistical calculations on the world’s fastest computers in order to be able to predict how epidemics of dangerous hospital bacteria spread. Studying the entire genomes of bacteria has now thrown open entirely new possibilities for revealing their secrets. It is this genetic knowledge that scientists use to understand bacterial epidemics.
17/08/2016Testing the impact of chemo toxicity on the human development without having to resort to animal testing: To get closer to this goal, the University of Veterinary Medicine Hannover, Foundation (TiHo) and the Laser Zentrum Hannover e.V. (LZH) are developing a new in-situ test method to examine the hazardous potential of chemical substances.
10/08/2016Researchers have succeeded in mapping out for the first time a complete production and treatment process, from using biotechnology to produce bacterial alginate, right through to producing fibres and manufacturing textile materials.
05/08/2016Researchers has developed a computer model that will aid in the design of nanocarriers, microscopic structures used to guide drugs to their targets in the body. The model better accounts for how the surfaces of different types of cells undulate due to thermal fluctuations, informing features of the nanocarriers that will help them stick to cells long enough to deliver their payloads.
04/08/2016MIT engineers have developed a microfluidic device that replicates the neuromuscular junction - the vital connection where nerve meets muscle. The device, about the size of a U.S. quarter, contains a single muscle strip and a small set of motor neurons. Researchers can influence and observe the interactions between the two, within a realistic, three-dimensional matrix.
02/08/2016It may be clammy and inconvenient, but human sweat has at least one positive characteristic - it can give insight to what is happening inside your body.
01/08/2016Researchers at CNRS, INSERM, Aix-Marseille University and AP-HM have just created a virtual brain that can reconstitute the brain of a person affected by epilepsy for the first time. From this work we understand better how the disease works and can also better prepare for surgery. These results are published in Neuroimage.
01/08/2016The University of Warwick has led the development of a cloud-based microbial bioinformatics resource, which is believed to be the largest of its kind in the world.
27/07/2016Many in the general public think scientific and technological innovations bring helpful change to society, but they are more concerned than excited when it comes to the potential use of emerging technologies to make people's minds sharper, their bodies stronger and healthier than ever before, according to a new Pew Research Center survey.
19/07/2016For the first time, researchers led by Tufts University engineers have integrated nano-scale sensors, electronics and microfluidics into threads - ranging from simple cotton to sophisticated synthetics - that can be sutured through multiple layers of tissue to gather diagnostic data wirelessly in real time, according to a paper published in Microsystems & Nanoengineering.
18/07/2016A new technique developed by a UBC researcher could make tissue regeneration cheaper and safer for health-care systems and their patients.
18/07/2016Overweight and obese women who lost weight through diet and exercise lowered the levels of certain proteins in their blood that play a role in angiogenesis, the process of blood vessel growth that can promote the growth and survival of cancer cells.
15/07/2016Ideally, injectable or implantable medical devices should not only be small and electrically functional, they should be soft, like the body tissues with which they interact. Scientists from two UChicago labs set out to see if they could design a material with all three of those properties.
06/07/2016Clinical trial data published in the Proceedings of the National Academy of Sciences (PNAS) demonstrates stimulating the vagus nerve with an implantable bioelectronic device significantly improved measures of disease activity in patients with rheumatoid arthritis (RA).
05/07/2016USC researcher Megan L. McCain and colleagues have devised a way to develop bigger, stronger muscle fibers. But instead of popping up on the bicep of a bodybuilder, these muscles grow on a tiny scaffold or "chip" molded from a type of water-logged gel made from gelatin.
17/06/2016People with diabetes often suffer from wounds that are slow to heal and can lead to ulcers, gangrene and amputation. New research from an international group led by Min Zhao, professor of ophthalmology and of dermatology at the University of California, Davis, shows that, in animal models of diabetes, slow healing is associated with weaker electrical currents in wounds.
17/06/2016A tiny mirror could make a huge difference for scientists trying to understand what's happening in the micron-scale structures of living cells.
02/06/2016Growing tissues and organs in the lab for transplantation into patients could become easier after scientists discovered an effective way to produce three-dimensional networks of blood vessels, vital for tissue survival yet a current stumbling block in regenerative medicine.
02/02/2015Only projects with a solid foundation are successful in the long run. This is also true for science. Biobanks are the most important component of this foundation when it comes to fundamental biomedical research: Only high quality tissue samples that are stored there make conclusive research possible - for example in search of the causes of tumorigenesis.
22/08/2014Besides antibiotics, vaccines may be the most important development in medicine: they protect us from diseases by “introducing” our immune system to pathogens. This way, a small injection saves us from severe and potentially mortal courses of disease.
22/04/2014The International Space Station ISS is not only the largest artificial object in space. It is also a laboratory for physicists, chemists, biologists and physicians and orbits earth at 28.000 kilometers per hour at an altitude of 400 kilometers. Thanks to this location, the ISS could one day make an important contribution to regenerative medicine.
