Published Global inventory of sound production brings us one step closer to understanding aquatic ecosystems
(via sciencedaily.com) Original source Our understanding of which aquatic species produce sounds just took a big step forward. Scientists have created an inventory of species confirmed or expected to produce sound underwater.
Published Some coral species might be more resilient to climate change than previously thought
(via sciencedaily.com) Original source Some coral species can be resilient to marine heat waves by 'remembering' how they lived through previous ones, research suggests.
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 15 most pressing issues for conservation, including invertebrate decline and changing marine ecosystems
(via sciencedaily.com) Original source Since 2009, the Cambridge Conservation Initiative has coordinated an annual horizon scan, a well-established method for predicting which threats, changes, and technologies will have the biggest impact on biological conservation in the following year. This year, the 15th horizon scan included 31 scientists, practitioners, and policymakers who developed a list of 96 issues, which they eventually narrowed down to the fifteen most novel and impactful. Their findings include topics related to sustainable energy, declining invertebrate populations, and changing marine ecosystems.
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 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 Whale-SETI: Groundbreaking encounter with humpback whales reveals potential for nonhuman intelligence communication
(via sciencedaily.com) Original source A team of scientists had a close encounter with a non-human (aquatic) intelligence. The Whale-SETI team has been studying humpback whale communication systems in an effort to develop intelligence filters for the search for extraterrestrial intelligence. In response to a recorded humpback 'contact' call played into the sea via an underwater speaker, a humpback whale named Twain approached and circled the team's boat, while responding in a conversational style to the whale 'greeting signal.' During the 20-minute exchange, Twain responded to each playback call and matched the interval variations between each signal.
Published This Japanese 'dragon' terrorized ancient seas
(via sciencedaily.com) Original source Researchers have described a Japanese mosasaur the size of a great white shark that terrorized Pacific seas 72 million years ago. The mosasaur was named for the place where it was found, Wakayama Prefecture. Researchers call it the Wakayama Soryu, which means blue dragon.
Published Underwater architects: The 'burrowing effect' of foraminifera on marine environments
(via sciencedaily.com) Original source Impact of single-cell organisms on sediment oxygen levels and bacterial diversity measured for the first time.
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.
