Published 'Genomic time machine' reveals secrets of our DNA
(via sciencedaily.com) Original source Researchers reveal a novel method to uncover bits of our genetic blueprint that come from ancient genetic parasites, offering fresh insights into human evolution and health.
Published A non-allergenic wheat protein for growing better cultivated meat
(via sciencedaily.com) Original source As the world's population increases, cultivated or lab-grown meat -- animal muscle and fat cells grown in laboratory conditions -- has emerged as a potential way to satisfy future protein needs. And edible, inexpensive plant proteins could be used to grow these cell cultures. Now, researchers report that the non-allergenic wheat protein glutenin successfully grew striated muscle layers and flat fat layers, which could be combined to produce meat-like textures.
Published High-efficiency carbon dioxide electroreduction system reduces our carbon footprint and progressing carbon neutrality goals
(via sciencedaily.com) Original source Global warming continues to pose a threat to human society and the ecological systems, and carbon dioxide accounts for the largest proportion of the greenhouse gases that dominate climate warming. To combat climate change and move towards the goal of carbon neutrality, researchers have developed a durable, highly selective and energy-efficient carbon dioxide (CO2) electroreduction system that can convert CO2 into ethylene for industrial purposes to provide an effective solution for reducing CO2 emissions.
Published How obesity dismantles our mitochondria
(via sciencedaily.com) Original source Researchers found that when mice were fed a high-fat diet, mitochondria within their fat cells broke apart and were less able to burn fat, leading to weight gain. They also found they could reverse the effect by targeting a single gene, suggesting a new treatment strategy for obesity.
Published Soap bark discovery offers a sustainability booster for the global vaccine market
(via sciencedaily.com) Original source A valuable molecule sourced from the soapbark tree and used as a key ingredient in vaccines, has been replicated in an alternative plant host for the first time, opening unprecedented opportunities for the vaccine industry.
Published How HIV smuggles its genetic material into the cell nucleus
(via sciencedaily.com) Original source Around one million individuals worldwide become infected with HIV, the virus that causes AIDS, each year. To replicate and spread the infection, the virus must smuggle its genetic material into the cell nucleus and integrate it into a chromosome. Research teams have now discovered that its capsid has evolved into a molecular transporter. As such, it can directly breach a crucial barrier, which normally protects the cell nucleus against viral invaders. This way of smuggling keeps the viral genome invisible to anti-viral sensors in the cytoplasm.
Published How macrophages regulate regenerative healing in spiny mice
(via sciencedaily.com) Original source A team of researchers is delving deeper into the science behind how spiny mice can regenerate lost tissue and using what they learn to trigger regeneration in other types of mice -- advances which one day may be translated into humans. Whereas adult laboratory mice heal injuries with scar tissue, spiny mice have the unique ability to regrow lost skin and regenerate musculoskeletal tissues in their body.
Published Cellular scaffolding rewired to make microscopic railways
(via sciencedaily.com) Original source Researchers were able to control the growth of thin, branching networks that support cellular structure and help cells function. The networks, called microtubules, can exert force and precisely transport chemicals at a subcellular level.
Published Teaching nature to break human-made chemical bonds
(via sciencedaily.com) Original source A newly evolved enzyme could one day make silicone compounds biodegradable.
Published The underground network: Decoding the dynamics of plant-fungal symbiosis
(via sciencedaily.com) Original source The intricate dance of nature often unfolds in mysterious ways, hidden from the naked eye. At the heart of this enigmatic tango lies a vital partnership: the symbiosis between plants and a type of fungi known as arbuscular mycorrhizal (AM) fungi. New groundbreaking research delves into this partnership, revealing key insights that deepen our understanding of plant-AM fungi interactions and could lead to advances in sustainable agriculture.
Published Simulations show how HIV sneaks into the nucleus of the cell
(via sciencedaily.com) Original source A new study has revealed how HIV squirms its way into the nucleus as it invades a cell.
Published Researchers pinpoint most likely source of HIV rebound infection
(via sciencedaily.com) Original source Antiretroviral therapy (ART) does an excellent job at suppressing HIV to undetectable levels in the blood. However, small amounts of latent virus hide throughout the body, and when treatment is stopped, it opens the door for the virus to rebound. Researchers identified which tissues SIV, the nonhuman primate version of HIV, reemerges from first, just seven days after ART is stopped.
Published How does HIV get into the cell's cenetr to kickstart infection?
(via sciencedaily.com) Original source UNSW Sydney medical scientists have cracked a mystery whose solution has long eluded researchers. UNSW Sydney medical scientists have cracked a mystery whose solution has long eluded researchers.
Published A new design improves water decontamination via plasma jet
(via sciencedaily.com) Original source Two research groups design a plasma (an ionized gas) reactor maintained by microwaves that makes it possible to decontaminate waters with high concentrations of dye.
Published Research of water droplet interfaces that offer the secret ingredient for building life
(via sciencedaily.com) Original source Scientists have experimental evidence that the key step in protein formation can occur in droplets of pure water.
Published New tool reveals gene behavior in bacteria
(via sciencedaily.com) Original source Researchers showed that the way in which genes are turned on and off as bacteria grow provide clues to their regulation.
Published New study unveils how plants control the production of reactive oxygen species
(via sciencedaily.com) Original source Reactive oxygen species (ROS), though generally regarded as toxic byproducts of biological processes, serve many important functions in plants. However, the precise mechanism that plants use to regulate the production of ROS remains elusive. In a recent study, researchers clarified how an important ROS-generating enzyme is activated, revealing mechanisms likely conserved across all land plants. Their findings could pave the way for breakthroughs in agricultural and environmental remediation tools.
Published Tiny worm, giant leap: Discovery of highly specific fatty acid attachment to proteins
(via sciencedaily.com) Original source In a world where the intricacies of molecular biology often seem as vast and mysterious as the cosmos, a new groundbreaking study delves into the microscopic universe of proteins, unveiling a fascinating aspect of their existence. This revelation could hold profound implications for the understanding and treatment of a myriad of human diseases.
Published New sustainable method for creating organic semiconductors
(via sciencedaily.com) Original source Researchers have developed a new, more environmentally friendly way to create conductive inks for use in organic electronics such as solar cells, artificial neurons, and soft sensors. The findings pave the way for future sustainable technology.
Published Don't overeat: How archaea toggle the nitrogen-uptake switch
(via sciencedaily.com) Original source By tightly regulating nitrogen uptake, microorganisms avoid overeating nitrogen and thus wasting energy. Scientists now reveal how some methanogenic archaea manage to do so.
