Published Spike in dermatology visits for skin problems seen during summer of wildfires
(via sciencedaily.com) Original source New research suggests that air pollution may contribute to the development or worsening of skin conditions. The work points to the need to improve air quality to lower the burden of skin disease, especially for vulnerable communities.
Published Algae as a surprising meat alternative and source of environmentally friendly protein
(via sciencedaily.com) Original source A new study has demonstrate that the ingestion of two of the most commercially available algal species are rich in protein which supports muscle remodeling in young healthy adults. Their findings suggest that algae may be an interesting and sustainable alternative to animal-derived protein with respect to maintaining and building muscle.
Published Wildfires increasing across Eastern U.S.
(via sciencedaily.com) Original source Researchers examined 36 years of wildfire data in the eastern United States, focusing on fires that burned large areas. The overall trend for the region showed an increase in fire size, frequency, and shifts in seasonality and highlights a need for proactive management and individual preparedness for those living in this populous part of the country.
Published New method Ebola virus uses to infect cells
(via sciencedaily.com) Original source Scientists recently published findings indicating that Ebola virus creates and uses intercellular tunnels to move from cell to cell and evade treatments.
Published Genetic atlas detailing early stages of zebrafish development
(via sciencedaily.com) Original source Researchers have published an atlas of zebrafish development, detailing the gene expression programs that are activated within nearly every cell type during the first five days of development, a period in which embryos mature from a single cell into distinct cell types.
Published Acid sensor and calcium store discovered in plants
(via sciencedaily.com) Original source Using optogenetics, researchers have detected a new acid sensor in plant cells that is addressing a cell-internal calcium store.
Published Opportunities to improve future HIV vaccine candidates
(via sciencedaily.com) Original source An effective HIV vaccine may need to prompt strong responses from immune cells called CD8+ T cells to protect people from acquiring HIV, according to a new study. The study findings draw comparisons between the immune system activity of past HIV vaccine study participants and people with HIV who naturally keep the virus from replicating even in the absence of antiretroviral therapy (ART). The latter individuals are often called 'long-term non-progressors' or 'elite controllers' (LTNPs/ECs).
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 Wildfires also impact aquatic ecosystems
(via sciencedaily.com) Original source Researchers have shown that the effects of wildfires are not limited to terrestrial ecosystems. Aquatic ecosystems are also undergoing rapid changes. The study found that fire debris transforms lakes and other aquatic ecosystems, with implications for fisheries and water quality.
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 sugar analysis could reveal different types of cancer
(via sciencedaily.com) Original source In the future, a little saliva may be enough to detect an incipient cancer. Researchers have developed an effective way to interpret the changes in sugar molecules that occur in cancer cells.
Published Twenty-year study confirms California forests are healthier when burned -- or thinned
(via sciencedaily.com) Original source A 20-year experiment in the Sierra Nevada confirms that different forest management techniques -- prescribed burning, restoration thinning or a combination of both -- are effective at reducing the risk of catastrophic wildfire in California. These treatments also improve forest health, making trees more resilient to stressors like drought and bark beetles, and they do not negatively impact plant or wildlife biodiversity within individual tree stands, the research found.
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 Climate change will increase wildfire risk and lengthen fire seasons
(via sciencedaily.com) Original source Wildfires are some of the most destructive natural disasters in the country, threatening lives, destroying homes and infrastructure, and creating air pollution. In order to properly forecast and manage wildfires, managers need to understand wildfire risk and allocate resources accordingly.
