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 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 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 Ecosystem benefits to humanity expected to decline by 9% by 2100
(via sciencedaily.com) Original source A new study of natural capital finds nature's benefits to humanity are expected to decline as climate change shifts ecosystems across borders.
Published Coral atoll islands may outpace sea-level rise with local ecological restoration, scientists say
(via sciencedaily.com) Original source Ecological restoration may save coral atoll islands from the rising seas of climate change, according to an international team of scientists, conservationists, and an indigenous leader.
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 How can Europe restore its nature?
(via sciencedaily.com) Original source Early 2024, the European Parliament will take a final vote on the 'Nature Restoration Law' (NRL), a globally unique but hotly debated regulation that aims to halt and reverse biodiversity loss in Europe. An international team of scientists has investigated the prospects of the new regulation.
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 Move over Blitzen: Geese outpace reindeer impacts on Arctic ecosystems
(via sciencedaily.com) Original source A research team is studying how expanding populations of two local herbivores -- reindeer and geese -- on Svalbard will impact the future of the ecosystem on the islands.
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 How forests smell -- a risk for the climate?
(via sciencedaily.com) Original source Plants emit odors for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers carried out a study to investigate how biodiversity influences the emission of these substances. For the first time, they were able to show that species-rich forests emit less of these gases into the atmosphere than monocultures. It was previously assumed that species-rich forests release more emissions. The Leipzig team has now been able to disprove this assumption experimentally.
Published Aquatic insects in restored streams need more rocks to lay their eggs
(via sciencedaily.com) Original source Likening it to providing more runways at busy airports, researchers at North Carolina State University found in a new study that adding protruding rocks to restored streams can help attract female aquatic insects that lay their eggs on the rock bottoms or sides.
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.
