Published Researchers model 'link' between improved photosynthesis and increased yield
(via sciencedaily.com) Original source A team has modeled improving photosynthesis through enzyme modification and simulated soybean growth with realistic climate conditions, determining to what extent the improvements in photosynthesis could result in increased yields.
Published Wiggly proteins guard the genome
(via sciencedaily.com) Original source Dynamic network in the pores of the nuclear envelope blocks dangerous invaders.
Published New mechanisms regulating plant response to temperature
(via sciencedaily.com) Original source Discovery of a new protein complex helps scientists understand how plants interpret changes in temperature over time
Published Herpes study adds to understanding of viral reinfections, how to potentially prevent them
(via sciencedaily.com) Original source A new study on herpes infections of the eye helps shed light on the question of viral reinfections by identifying a key protein involved in viral reinfections that could be targeted by antiviral drugs.
Published Mushrooms and their post-rain, electrical conversations
(via sciencedaily.com) Original source Certain types of fungi can communicate with each other via electrical signals. But much remains unknown about how and when they do so. A group of researchers recently headed to the forest to measure the electrical signals of Laccaria bicolor mushrooms, finding that their electrical signals increased following rainfall.
Published Ecosystem evolution in Africa
(via sciencedaily.com) Original source New research pushes back the oldest evidence of C4 grass-dominated habitats in Africa -- and globally -- by more than 10 million years, with important implications for primate evolution and the origins of tropical C4 grasslands and savanna ecosystems across the African continent and around the world.
Published Scientists identify antivirals that could combat emerging infectious diseases
(via sciencedaily.com) Original source A new study has identified potential broad-spectrum antiviral agents that can target multiple families of RNA viruses that continue to pose a significant threat for future pandemics.
Published Scientists slow aging by engineering longevity in cells
(via sciencedaily.com) Original source Researchers have developed a biosynthetic 'clock' that keeps cells from reaching normal levels of deterioration related to aging. They engineered a gene oscillator that switches between the two normal paths of aging, slowing cell degeneration and setting a record for life extension.
Published Pulling the plug on viral infections: CRISPR isn't just about cutting
(via sciencedaily.com) Original source CRISPR claimed scientific fame for its ability to quickly and accurately edit genes. But, at the core, CRISPR systems are immune systems that help bacteria protect themselves from viruses. A new study reveals a previously unrecognized player in one such system -- a membrane protein that enhances anti-viral defense. According to study authors, the finding upends the idea that CRISPR systems mount their defense only by degrading RNA and DNA in cells.
Published Information 'deleted' from the human genome may be what made us human
(via sciencedaily.com) Original source What the human genome is lacking compared with the genomes of other primates might have been as crucial to the development of humankind as what has been added during our evolutionary history, according to a new study led by researchers at Yale and the Broad Institute of MIT and Harvard. The new findings, published April 28 in the journal Science, fill an important gap in what is known about historical changes to the human genome.
Published Mammalian evolution provides hints for understanding the origins of human disease
(via sciencedaily.com) Original source Even though it is important to know where these variations are located in the genome, it's also useful to know how or why these genetic variations happened in the first place.
Published Ant mounds are more important for biodiversity than previously thought
(via sciencedaily.com) Original source The ant mounds on the heath, in the forest and in your garden are oases for life. The heat and nutrients from ant mounds make them the perfect home for unique plant and animal species, according to new research.
Published Maths unlocks molecular interactions that open window to how life evolved
(via sciencedaily.com) Original source Landmark research by mathematicians sets out the definitive picture of biological adaptation at the level of intermolecular interactions.
Published New findings indicate gene-edited rice might survive in Martian soil
(via sciencedaily.com) Original source New research suggests future Martian botanists may be able to grow gene-edited rice on Mars.
Published How the Amazon rainforest is likely to cope with the effect of future drought
(via sciencedaily.com) Original source A major collaboration involving 80 scientists from Europe and South America has identified the regions of the Amazon rainforest where trees are most likely to face the greatest risk from drier conditions brought about by climate change. Based on the analysis, the scientists predict trees in the western and southern Amazon face the greatest risk of dying. They also warn that previous scientific investigations may have underestimated the impact of drought on the rainforest because those studies focused on the central-eastern part of the forest, which is the least vulnerable to drought.
Published Prehistoric scat reveals 'Waves' of extinction in Colombia
(via sciencedaily.com) Original source Fungal spores found in dung have revealed that large animals went extinct in two 'waves' in the Colombian Andes.
Published Near-universal T cell immunity towards a broad range of bacteria
(via sciencedaily.com) Original source Typically T cells of the immune system respond to a specific feature (antigen) of a microbe, thereby generating protective immunity. Scientists have discovered an exception to this rule. Namely, a group of divergent bacterial pathogens, including pneumococci, all share a small highly conserved protein sequence, which is both presented and recognized by human T cells in a conserved population-wide manner.
Published Ocean ecosystem: Mixotrophic microorganisms play key role
(via sciencedaily.com) Original source Researchers have identified a previously unknown group of bacteria, called UBA868, as key players in the energy cycle of the deep ocean. They are significantly involved in the biogeochemical cycle in the marine layer between 200 and 1000 meters.
Published Luring the virus into a trap
(via sciencedaily.com) Original source Viruses like influenza A and Ebola invade human cells in a number of steps. Research teams investigated the final stages of viral penetration using electron tomography and computer simulations. So-called fusion pores, through which the viral genome is released into the host cell, play a central role in these processes. If they can be prevented from forming, the virus is also blocked. The Heidelberg scientists describe previously unknown mechanisms, which might lead to new approaches to prevent infections.
Published Researchers reveal an ancient mechanism for wound repair
(via sciencedaily.com) Original source The study is the first to identify a damage response pathway that is distinct from but parallel to the classical pathway triggered by pathogens.
