source: Phys.org Research led by Queen Mary University of London, King’s College London and the Francis Crick Institute has identified a protein that makes melanoma, the most serious type of skin cancer, more aggressive by giving cancer cells the ability to change the shape of their nucleus—a characteristic that allows the cells to migrate and spread around the body.

source: Phys.org The moon has been considered extremely reductive since the Apollo era, as estimated by the low ferric iron content in lunar samples returned in the 1970s. In addition, it has long been a mystery whether a large amount of ferric iron exists on the moon and how it is formed. Read Full Article Here

source: Phys.org Smallpox was once one of humanity’s most devastating diseases, but its origin is shrouded in mystery. For years, scientific estimates of when the smallpox virus first emerged have been at odds with historical records. Now, a new study reveals that the virus dates back 2,000 years further than scientists have previously shown, verifying historical sources and confirming for the first time that the disease has plagued human societies since ancient times.

source: Phys.org One of the most widespread zoonoses worldwide, toxoplasmosis is an infectious disease that is caused by the parasite Toxoplasma gondii. Although cats are the final host, the parasite can infest any warm-blooded animal, including humans. In an investigation of how the pathogen manages to infect such a broad range of hosts, a team led by Prof. Markus Meissner, chair of experimental parasitology at LMU, has identified a central protein complex.

source: Phys.org Mosquitoes spread several diseases, among them malaria and dengue virus. In 2020, about 241 million cases of malaria occurred worldwide, with a few more million cases occurring in 2021. Nearly half the world’s population lives in regions where contracting dengue virus is a risk. Insects also destroy a third of agriculture. Read Full Article Here

source: Phys.org Before mixing an oil-and-vinegar-based salad dressing, the individual drops of vinegar are easily seen suspended in the oil, each with a perfectly circular boundary that delineates the two liquids. In the same way, our cells contain condensed bundles of proteins and nucleic acids called condensates delineated by clear boundaries. The boundaries are known as interfaces and given that condensates talk to one another through their interfaces, the structural features of the interface are of significant interest.
