|  Engineers make strides toward artificial cartilage  | A research team has developed a better recipe for synthetic replacement cartilage in joints, calling for a newly designed durable hydrogel to be poured over a three-dimensional fabric "scaffold." | Read More » Disease, not climate change, fueling frog declines in the Andes  | Climate change is widely believed to be behind the rapid decline of frog populations in the Andes mountains, but a new study finds that the real culprit is a deadly fungus that has wiped out amphibian species worldwide. Researchers found that highland frogs, while tolerant of increasing temperatures, live in the optimal temperature range for Batrachochytrium dendrobatidis, also known as Bd. | Read More » Jailhouse wine not as delicious as it sounds, could be deadly  | In a case series seemingly tailor-made for cinematic tragedy or farce, emergency physicians report severe botulism poisoning from a batch of potato-based "wine" (also known as pruno) cooked up in a Utah prison. | Read More » Misunderstanding of palliative care leads to preventable suffering  | A new review says palliative care's association with end of life has created an "identity problem" that means the majority of patients facing a serious illness do not benefit from treatment of the physical and psychological symptoms that occur throughout their disease. | Read More » Zebrafish help decode link between calcium deficiency, colon cancer  | A tiny, transparent fish embryo and a string of surprises led scientists to a deeper understanding of the perplexing link between low calcium and colon cancer. | Read More » Clot-busters, caught on tape  | Ultrasound-stimulated microbubbles have been showing promise in recent years as a non-invasive way to break up dangerous blood clots. But though many researchers have studied the effectiveness of this technique, not much was understood about why it works. Now a team of researchers has collected the first direct evidence showing how these wiggling microbubbles cause a blood clot's demise. | Read More » A stop sign for cancer  | A particularly aggressive form of leukemia is the acute lymphoblastic leukemia (ALL). It is especially common among children and very difficult to treat. Researchers have now discovered completely new targets for the treatment of blood cancers. Studying the cancer protein STAT5, the scientists found new opportunities for the development of effective anti-cancer drugs. | Read More » Swirls in remnants of Big Bang may hold clues to universe's infancy  | South Pole Telescope scientists have detected for the first time a subtle distortion in the oldest light in the universe, which may help reveal secrets about the earliest moments in the universe's formation. | Read More » Ethanol blends carry hidden risk  | Blending more ethanol into fuel to cut air pollution carries a hidden risk that toxic or explosive gases may leach into buildings, according to researchers. | Read More » POPUP: Novel organic solar cells  | Future solar cells will be light and mechanically flexible. They will be produced at low costs with the help of printing processes. Scientists aim at developing more efficient materials and new architectures for organic photovoltaic devices. They are working on improving the basic understanding and developing new architectures for semitransparent and non-transparent solar cells and modules. | Read More » New discovery on how skin cells form 'bridges' paves the way for advances in wound healing and tissue engineering  | Scientists have discovered that outer skin cells are able to unite to form suspended "bridges" during wound healing. The new findings will pave the way for tissue engineering, such as the design of artificial skin, and better wound treatment. | Read More » Evidence of mass extinction associated with climate change 375 million years ago discovered in Central Asia  | Scientists have found evidence for catastrophic oceanographic events associated with climate change and a mass extinction 375 million years ago that devastated tropical marine ecosystems. | Read More » First rock dating experiment performed on Mars  | Although researchers have determined the ages of rocks from other planetary bodies, the actual experiments -- like analyzing meteorites and moon rocks -- have always been done on Earth. Now, for the first time, researchers have successfully determined the age of a Martian rock -- with experiments performed on Mars. This work could not only help in understanding the geologic history of Mars but also aid in the search for evidence of ancient life there. | Read More » | |
