We need your help to achieve the goal of growing our online, geographically searchable database of resources and support for cancer patients, their families and caregivers. Whether you're in the initial phase of shock, in the battle, or handling the aftermath of cancer, our resources take out the stress of searching multiple places and thousands of online listings.
Tokyo, Japan - Researchers from Tokyo Metropolitan University have used machine learning to study spin models, used in physics to study phase transitions. Previous work showed that image/handwriting classifying AI could be applied to distinguish states in the simplest models. The team showed the approach is applicable to more complex models and found that an AI trained on one model and applied to another could reveal key similarities between distinct phases in different systems.
Using a newly developed laboratory model of three types of brain cells, Penn and CHOP scientists reveal how HIV infection -- as well as the drugs that treat it -- can take a toll on the central nervous system.
Because of poor dates for land fossils laid down before and after the mass extinction at the end of the Permian, paleontologists assumed that the terrestrial extinctions from Gondwana occurred at the same time as the better-documented marine extinctions. But a new study provides more precise dates for South African fossils and points to a long, perhaps 400,000-year period of extinction on land before the rapid marine extinction 252 million years ago.
Oncotarget Volume 11, Issue 12 reported outside its natural niche, the cultured prostate cancer stem cells lost their tumor-inducing capability and stem cell marker expression after approximately 8 transfers at a 1:3 split ratio.

When a one-dimensional gas of strongly interacting bosons expands, the velocity distribution of the bosons transforms into one that is identical to non-interacting fermions.
Consumers browse social media and product pages two weeks before final hedonic purchases, utilize third-party reviews up to two weeks before final utilitarian purchases, and use search engines, deals, and competitors' product pages closer to utilitarian purchases.
Rice University theorists find that flexoelectric effects in double-walled carbon nanotubes could be highly useful for photovoltaic applications.
An international team with the participation of Prof. Dr. Michael Kues from the Cluster of Excellence PhoenixD at Leibniz University Hannover has developed a new method for generating quantum-entangled photons in a spectral range of light that was previously inaccessible. The discovery can make the encryption of satellite-based communications much more secure in the future.
A stem cell biologist from City University of Hong Kong (CityU), together with his collaborators, has developed a novel strategy, called in vivo priming, to 'train' the stem cells to stay strong after implantation to the damaged heart via the 3D-printed bandage-like patch. The positive results of the study show that an in vivo priming strategy can be an effective means to enhance cardiac repair.
