Published Tomato juice's antimicrobial properties can kill salmonella
(via sciencedaily.com) Original source New research shows that tomato juice can kill Salmonella Typhi and other bacteria that can harm people's digestive and urinary tract health.
Published Structural color ink: Printable, non-iridescent and lightweight
(via sciencedaily.com) Original source A new way of creating color uses the scattering of light of specific wavelengths around tiny, almost perfectly round silicon crystals. This development enables non-fading structural colors that do not depend on the viewing angle and can be printed. The material has a low environmental and biological impact and can be applied extremely thinly, promising significant weight improvements over conventional paints.
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 Probiotics promote weight loss in obese dogs
(via sciencedaily.com) Original source New research demonstrates how probiotics can reshape the gut microbiome and energy metabolism in dogs.
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 Cosmic building blocks of life discovered through the electron microscope
(via sciencedaily.com) Original source Meteorites are fragments of asteroids which find their way to Earth as shooting stars and provide information on the origins of our solar system. A team of researchers has examined the so-called Winchcombe meteorite and demonstrated the existence in it of nitrogen compounds such as amino acids and heterocyclic hydrocarbons -- without applying any chemical treatment and by using a new type of detector design.
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 Researchers map genome for cats, dolphins, birds, and dozens of other animals
(via sciencedaily.com) Original source Researchers mapped genetic blueprints for 51 species including cats, dolphins, kangaroos, penguins, sharks, and turtles, a discovery that deepens our understanding of evolution and the links between humans and animals. The researchers developed novel algorithms and computer software that cut the sequencing time from months -- or decades in the case of the human genome -- to a matter of days.
Published Locusts' sense of smell boosted with custom-made nanoparticles
(via sciencedaily.com) Original source Scientists have harnessed the power of specially made nanostructures to enhance the neural response in a locust's brain to specific odors and to improve their identification of those odors.
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 Turning glass into a 'transparent' light-energy harvester
(via sciencedaily.com) Original source Physicists propose a novel way to create photoconductive circuits, where the circuit is directly patterned onto a glass surface with femtosecond laser light. The new technology may one day be useful for harvesting energy, while remaining transparent to light and using a single material.
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 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.
