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 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 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 Shining a light on the hidden properties of quantum materials
(via sciencedaily.com) Original source Certain materials have desirable properties that are hidden and scientists can use light to uncover these properties. Researchers have used an advanced optical technique, based on terahertz time-domain spectroscopy, to learn more about a quantum material called Ta2NiSe5 (TNS).
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 Researchers add a 'twist' to classical material design
(via sciencedaily.com) Original source Researchers grew a twisted multilayer crystal structure for the first time and measured the structure's key properties. The twisted structure could help researchers develop next-generation materials for solar cells, quantum computers, lasers and other devices.
Published What coffee with cream can teach us about quantum physics
(via sciencedaily.com) Original source A new advancement in theoretical physics could, one day, help engineers develop new kinds of computer chips that might store information for longer in very small objects.
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 Gravity helps show strong force strength in the proton
(via sciencedaily.com) Original source New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force, a powerful mediator of particle interactions in the subatomic realm. The research has revealed, for the first time, a snapshot of the distribution of the shear strength of the strong force inside the proton -- or how strong an effort must be to overcome the strong force to move an object it holds in its grasp. At its peak, the nuclear physicists found that a force of over four metric tons would be required to overcome the binding power of the strong force.
Published Researchers find new multiphoton effect within quantum interference of light
(via sciencedaily.com) Original source An international team of researchers has disproved a previously held assumption about the impact of multiphoton components in interference effects of thermal fields (e.g. sunlight) and parametric single photons (generated in non-linear crystals).
Published Complex green organisms emerged a billion years ago
(via sciencedaily.com) Original source Of all the organisms that photosynthesize, land plants have the most complex form. How did this morphology emerge? A team of scientists has taken a deep dive into the evolutionary history of morphological complexity in streptophytes, which include land plants and many green algae. Their research allowed them to go back in time to investigate lineages that emerged long before land plants existed.
Published New research guides mathematical model-building for gene regulatory networks
(via sciencedaily.com) Original source A newly published study provides guidance for building accurate mathematical models for gene regulatory networks.
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 research sheds light on a phenomenon known as 'false vacuum decay'
(via sciencedaily.com) Original source Scientists have produced the first experimental evidence of vacuum decay.
Published Single-celled kamikazes spearhead bacterial infection
(via sciencedaily.com) Original source You suddenly feel sick -- pathogenic bacteria have managed to colonize and spread in your body! The weapons they use for their invasion are harmful toxins that target the host's defense mechanisms and vital cell functions. Before these deadly toxins can attack host cells, bacteria must first export them from their production site -- the cytoplasm -- using dedicated secretion systems.
Published A window into plant evolution: The unusual genetic journey of lycophytes
(via sciencedaily.com) Original source An international team of researchers has uncovered a remarkable genetic phenomenon in lycophytes, which are similar to ferns and among the oldest land plants. Their study reveals that these plants have maintained a consistent genetic structure for over 350 million years, a significant deviation from the norm in plant genetics.
