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 Unexpected biodiversity on the ocean floor
(via sciencedaily.com) Original source Hydrothermal vents and manganese nodule fields in the deep oceans contain more biodiversity than expected.
Published Diverse forests are best at standing up to storms
(via sciencedaily.com) Original source European forests with a greater diversity of tree species are more resilient to storms, according to new research.
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 World's first successful embryo transfer in rhinos paves the way for saving the northern white rhinos from extinction
(via sciencedaily.com) Original source Scientists have succeeded in achieving the world's first pregnancy of a rhinoceros after an embryo transfer. The southern white rhino embryo was produced in vitro from collected egg cells and sperm and transferred into a southern white rhino surrogate mother at the Ol Pejeta Conservancy in Kenya on September 24, 2023. The BioRescue team confirmed a pregnancy of 70 days with a well-developed 6.4 cm long male embryo. The successful embryo transfer and pregnancy are a proof of concept and allow to now safely move to the transfer of northern white rhino embryos -- a cornerstone in the mission to save the northern white rhino from extinction.
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 Study in mice uncovers new protective benefit of breast milk
(via sciencedaily.com) Original source An immune component of breast milk known as the complement system shapes the gut environment of infant mice in ways that make them less susceptible to certain disease-causing bacteria, according to a new study.
Published DNA from preserved feces reveals ancient Japanese gut environment
(via sciencedaily.com) Original source DNA from ancient feces can offer archaeologists new clues about the life and health of Japanese people who lived thousands of years ago, according to a new study.
Published Sparrows uniquely adapted to Bay Area marshes are losing their uniqueness
(via sciencedaily.com) Original source How does loss of habitat affect the animals still living there? A genetic study of saltwater-adapted Savannah sparrows around the San Francisco Bay Area shows that the 90% loss of tidal marsh habitat has led to more interbreeding with freshwater-adapted Savannah sparrows, diminishing their genetic adaptation to saltwater, such as enlarged kidneys and larger beak. This could lessen their ability to live in a saltwater habitat.
Published Microplastics may be accumulating rapidly in endangered Galápagos penguins' food web
(via sciencedaily.com) Original source Model predictions showed a rapid increase in microplastic accumulation and contamination across the penguins' prey organisms resulting in Galapagos penguin showing the highest level of microplastics per biomass, followed by barracuda, anchovy, sardine, herring, and predatory zooplankton.
Published Humpback whales move daytime singing offshore
(via sciencedaily.com) Original source New research revealed a daily pattern wherein humpback whales move their singing away from shore throughout the day and return to the nearshore in the evening.
Published Innovative microscopy technique reveals secrets of lipid synthesis inside cells
(via sciencedaily.com) Original source Researchers have made a pivotal discovery in the field of cellular microscopy. The team has successfully developed Two-Color Infrared Photothermal Microscopy (2C-IPM), a novel technology designed to investigate neutral lipids within lipid droplets of living cells. This new microscopy can be used with isotope labeling, which allows for the detailed monitoring of neutral lipid synthesis within individual lipid droplets.
Published Self-powered movable seawall for tsunami protection and emergency power generation
(via sciencedaily.com) Original source A movable seawall system, capable of generating sufficient electricity to raise gates and protect ports against tsunamis, has been proposed by researchers. The system has been found feasible in areas prone to Nankai Trough earthquake tsunamis. Additionally, it can generate surplus energy to supply emergency power to ports during power outages that commonly occur in natural disasters. This innovative system integrates disaster prevention with the use of renewable energy.
Published Global warming has a bigger effect on compact, fast-moving typhoons
(via sciencedaily.com) Original source A group has found that larger, slow-moving typhoons are more likely to be resilient to the effects of global warming. However, more compact, fast-moving storms are more likely to be sensitive. These findings suggest an improved method for projecting the strength of typhoons under global warming conditions.
Published Researchers advocate for sustainable logging to safeguard against global flood risks
(via sciencedaily.com) Original source It's time to recognize the power of healthy forests in managing global growing flood risk, and to shift towards more sustainable forestry practices and policy.
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 The complexity of forests cannot be explained by simple mathematical rules, study finds
(via sciencedaily.com) Original source The way trees grow together do not resemble how branches grow on a single tree, scientists have discovered.
Published War in Ukraine severely limits ability to track Arctic climate change
(via sciencedaily.com) Original source Scientists no longer have direct access to data from Russian Arctic research stations. Without this data, our view of climate changes in the region is increasingly biased, new research shows.
Published Ancient brown bear genomes sheds light on Ice Age losses and survival
(via sciencedaily.com) Original source The brown bear is one of the largest living terrestrial carnivores, and is widely distributed across the Northern Hemisphere. Unlike many other large carnivores that went extinct at the end of the last Ice Age (cave bear, sabretoothed cats, cave hyena), the brown bear is one of the lucky survivors that made it through to the present. The question has puzzled biologists for close to a century -- how was this so?
