Many of the secrets of cancer and other diseases lie in the cell's nucleus. But getting way down to that level -- to see and investigate the important genetic material housed there -- requires creative thinking and extremely powerful imaging techniques. Vadim Backman and Hao Zhang, nanoscale imaging experts at Northwestern University, have developed a [...]
From phys.org: NASA is inviting the public to help search for possible undiscovered worlds in the outer reaches of our solar system and in neighboring interstellar space. A new website, called Backyard Worlds: Planet 9, lets everyone participate in the search by viewing brief movies made from images captured by NASA's Wide-field Infrared Survey Explorer [...]
Determining the exact configuration of proteins and other complex biological molecules is an important step toward understanding their functions, including how they bind with receptors in the body. But such imaging is difficult to do. It usually requires the molecules to be crystallized first so that X-ray diffraction techniques can be applied — and not [...]
Using tiny snippets of DNA as "barcodes," researchers have developed a new technique for rapidly screening the ability of nanoparticles to selectively deliver therapeutic genes to specific organs of the body. The technique could accelerate the development and use of gene therapies for such killers as heart disease, cancer and Parkinson's disease. Genetic therapies, such [...]
From Nanowerk News: 25 years have passed since the publication of the first work on solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) as a system for delivering drugs. So the European Journal of Pharmaceutics and Biopharmaceutics ("Applications of lipid nanoparticles in gene therapy") has prepared a special edition for which it asked the [...]
SpaceX's Falcon 9 rocket has gone vertical at NASA's historic Launch Complex 39A (LC-39A) for the first time. The California-based company is getting ready for a planned Feb. 18 liftoff from LC-39A, which is part of NASA's Kennedy Space Center in Florida. The Falcon 9 will blast SpaceX's robotic Dragon cargo capsule toward the International [...]
Backed by stunning illustrations, David Christian narrates a complete history of the universe, from the Big Bang to the Internet, in a riveting 18 minutes. This is "Big History": an enlightening, wide-angle look at complexity, life and humanity, set against our slim share of the cosmic timeline. [title size="2" content_align="left" style_type="single [...]
From Nanowerk News: Scientists at The Australian National University (ANU) have controlled wave-generated currents to make previously unimaginable liquid materials for new technological innovations, including techniques to manipulate micro-organisms. The new kind of dynamic material could be revolutionary, similar to other materials created in recent decades that have been used for invisibility cloaking, superlenses and [...]
From medgadget.com: Researchers at Rice University have come up with a better X-ray contrast agent, which may allow for very precise tracking of cells, biomolecules, and other particles within the body. In particular, the researchers believe that seeing whether stem cells are moving towards and healing diseased tissue will be one of the first important [...]
From an article by Rae Paoletta at Gizmodo: Spaceflight is not for the faint of heart—literally. The first results of NASA’s twin study, released just this week, revealed that space physically impacts astronauts on multiple levels, right down to shifts in gene expression. Now, a group of scientists at the University of Michigan have released [...]
