Published How the immune system fights to keep herpes at bay
(via sciencedaily.com) Original source In a study of lab-engineered cells, researchers identify how the immune system neutralizes the herpesvirus. The research maps, for the first time, the maneuvers used by virus and host in the cell nucleus, a poorly understood terrain of host-pathogen interaction. The findings could inform the design of new treatments for herpes and other viruses that replicate in the same way.
Published New understanding of ancient genetic parasite may spur medical breakthroughs
(via sciencedaily.com) Original source Researchers have determined the structure of the most common material in our genomes. New treatments for autoimmune diseases, cancer and neurodegeneration may follow.
Published Enzymes can't tell artificial DNA from the real thing
(via sciencedaily.com) Original source Researchers have come one step closer to unlocking the potential of synthetic DNA, which could help scientists develop never-before-seen proteins in the lab.
Published Scientists unveil complete cell map of a whole mammalian brain
(via sciencedaily.com) Original source Researchers have created a complete cell atlas of a whole mammalian brain. This atlas serves as a map for the mouse brain, describing the type, location, and molecular information of more than 32 million cells and providing information on connectivity between these cells.
Published Cells move in groups differently than they do when alone
(via sciencedaily.com) Original source A protein that helps generate the force needed for single cells to move works differently in cells moving in groups, a new study shows.
Published Mice possess natural gene therapy system
(via sciencedaily.com) Original source A previously mysterious small RNA molecule in mice is found to play a crucial role in gene expression, and may be the first identified member of a new class of regulatory RNAs.
Published A rare enzyme role change with bacterial defense system assembly
(via sciencedaily.com) Original source Scientists have revealed a never-before-seen phenomenon in a protein: Alone, the enzyme processes DNA and RNA but, when bound to another protein as part of a defense system, interacts with a completely different type of compound to help bacteria commit suicide.
Published A new mechanism by which rotavirus makes you sick
(via sciencedaily.com) Original source Scientists report a new mechanism by which rotavirus induces diarrhea by interfering with the normal absorption of nutrients in the intestine.
Published Zika's shape-shifting machinery, and a possible vulnerability
(via sciencedaily.com) Original source Viruses have limited genetic material -- and few proteins -- so all the pieces must work extra hard. Zika is a great example; the virus only produces 10 proteins. Now researchers have shown how the virus does so much with so little and may have identified a therapeutic vulnerability.
Published World's first logical quantum processor
(via sciencedaily.com) Original source A team has realized a key milestone in the quest for stable, scalable quantum computing. For the first time, the team has created a programmable, logical quantum processor, capable of encoding up to 48 logical qubits, and executing hundreds of logical gate operations. Their system is the first demonstration of large-scale algorithm execution on an error-corrected quantum computer, heralding the advent of early fault-tolerant, or reliably uninterrupted, quantum computation.
Published How immune cells recognize their enemies
(via sciencedaily.com) Original source In order for immune cells to do their job, they need to know against whom they should direct their attack. Research teams a have identified new details in this process.
Published New genes can arise from nothing
(via sciencedaily.com) Original source The complexity of living organisms is encoded within their genes, but where do these genes come from? Researchers resolved outstanding questions regarding the origin of small regulatory genes, and described a mechanism that creates their DNA palindromes. Under suitable circumstances, these palindromes evolve into microRNA genes.
Published Molecular fossils shed light on ancient life
(via sciencedaily.com) Original source Paleontologists are getting a glimpse at life over a billion years in the past based on chemical traces in ancient rocks and the genetics of living animals. New research combines geology and genetics, showing how changes in the early Earth prompted a shift in how animals eat.
Published Fungus-fighting protein could help overcome severe autoimmune disease and cancer
(via sciencedaily.com) Original source A protein in the immune system programmed to protect the body from fungal infections is also responsible for exacerbating the severity of certain autoimmune diseases such as irritable bowel disease (IBS), type 1 diabetes, eczema and other chronic disorders, new research has found. The discovery could pave the way for new and more effective drugs, without the nasty side effects of existing treatments. In addition to helping to manage severe autoimmune conditions, the breakthrough could also help treat all types of cancer.
Published Influx of water and salts propel immune cells through the body
(via sciencedaily.com) Original source Researchers have shown that an influx of water and ions into immune cells allows them to migrate to where they're needed in the body.
Published From infamy to ingenuity: Bacterial hijack mechanisms as advanced genetic tools
(via sciencedaily.com) Original source Researchers have uncovered the intricate molecular mechanism used by parasitic phytoplasma bacteria, known for inducing 'zombie-like' effects in plants.
Published 'Shocking' discovery: Electricity from electric eels may transfer genetic material to nearby animals
(via sciencedaily.com) Original source Researchers have discovered that electric eels can alter the genes of tiny fish larvae with their electric shock. Their findings help to better understand electroporation, a method by which genes can be transported using electricity.
Published Diamonds and rust help unveil 'impossible' quasi-particles
(via sciencedaily.com) Original source Researchers have discovered magnetic monopoles -- isolated magnetic charges -- in a material closely related to rust, a result that could be used to power greener and faster computing technologies.
Published Sugar permeation discovered in plant aquaporins
(via sciencedaily.com) Original source Aquaporins, which move water through membranes of plant cells, were not thought to be able to permeate sugar molecules, but researchers have observed sucrose transport in plant aquaporins for the first time, challenging this theory.
Published Macrophages 'eat' insulin-producing cells to regulate insulin after mice have given birth
(via sciencedaily.com) Original source Pregnancy brings a rise in pancreatic beta cells -- the cells that produce insulin. Shortly after birth, these cells return to their normal levels. The mechanisms behind this process had remained a mystery. But now a research group has revealed that white blood cells called macrophages 'eat' these cells.
