Moffitt study may lead to potential treatment options for cutaneous T cell lymphoma Cutaneous T cell lymphomas (CTCLs) are a group of non-Hodgkin lymphomas that develop from T cells and mainly impact the skin with painful lesions. The two main subtypes of CTCL are mycosis fungoides and Sézary syndrome. CTCLs are extremely rare, with approximately six cases per 1 million people each year. It is unclear how CTCL develops, and unfortunately there are limited treatment options and no cure. Moffitt...

Climate Change Could Affect Ecological Balance in Higher Altitudes Written by AZoCleantechDec 18 2020 Planet Earth is getting warmer by the day, making several organisms native to lower elevations or latitudes move higher. Roesel’s bush-cricket is one of the many grasshoppers that might migrate to higher elevations once the climate in lower elevations has become unsuitable. Image Credit: Christian Roesti. When novel organisms move into a new habitat, they could influence the ecological balan...

FAT1 mutations act as tumor suppressor and prevent cancer development, indicates study Cancer metastasis, which is the dissemination of tumor cells into distant organs, is the leading cause of mortality in cancer patients. To undergo metastasis, cells must leave the primary tumor, circulate into the blood, colonize distant organs, and form distant metastasis. It has been proposed that epithelial to mesenchymal transition (EMT), a process in which epithelial cells detach from their neighboring c...

Silica is the Most Eco-Friendly Substitute for Plastic Microbeads Used in Cosmetics Written by AZoMDec 15 2020 A new study quantifies the environmental costs of alternative materials following bans on plastic microbeads used in wash-off cosmetics. Silica, applied here as mud in the Blue Lagoon in Iceland, was the most environmentally friendly alternative. Image Credit: Imperial College London. Microbeads are added to cosmetic and personal care products such as toothpaste, industrial hand cleane...

Study: Silica offers the best environmental alternative to plastic microbeads Following bans on plastic microbeads in wash-off cosmetics, a new study weighs up the environmental costs of alternatives. Microbeads have been included in personal care and cosmetic products ranging from toothpaste and sunscreen to body scrubs and industrial hand cleaners, usually to improve qualities like abrasiveness. Microbeads are small, manufactured plastic pellets, typically measuring less than 0.5 millimetres ...

Researchers Simulate Glass-Forming Ability of Metallic Mixtures Written by AZoMDec 14 2020 Scientists at The University of Tokyo use computer simulations to model the effects of elemental composition on the glass-forming ability of metallic mixtures, which may lead to tough, electroconductive glasses.

The team has demonstrated that even minuscule variations in composition could highly impact the probability that a material ...

Microplastic particles find their way into living cells if exposed to natural aquatic environments The environment is polluted by microplastics worldwide. The tiny particles enter food chains, and thereby the digestive systems of animals and humans; moreover, they can be inhaled. Instead of being excreted, small microplastics can be incorporated into the body tissue. A research team at the University of Bayreuth has now discovered that microplastic particles find their way into living cells mor...

Humans, followed by ferrets and to a lesser extent cats, civets and dogs are the most susceptible animals to SARS-CoV-2 infection, according to an analysis of ten different species carried out by researchers at the Centre for Genomic Regulation (CRG), based in Barcelona.

New Technique to Use Bacterial Nanopores to Decode Digital Information   Image Credit: Billion Photos/Shutterstock In 2020, every individual in the world is generating around 1.7 MB of data each second and that data amounts to 418 zettabytes, or 418 billion one-terabyte hard drives, in just a single year.   Data is currently stored as 0s and 1s in optical or magnetic systems that do not last for 100 years. In the meantime, data centers use large amounts of energy and create colossal carbon f...
