  Moons scientifically important sites may be lost for ever in Mining Rush. Researchers seek protection for pristine areas of moons far side and polar regions. The moon is becoming a potential battleground where scientific exploration collides with commercial interests, as NASA launches its first lunar mission in half a century. Scheduled for later this year, Peregrine Mission 1, created by the private company Astrobotic, ushers in a new era in lunar exploration. Many more missions, including those under NASA's Artemis program, are set to follow, sparking excitement among researchers about a potential golden age of exploration. However, there are concerns that the growth of private landers could trigger a "moon-rush", with companies looking to exploit valuable minerals and resources, potentially compromising scientifically significant lunar sites. Because private entities lack sufficient legal protection for these areas under current space laws, scientists are imm...

  Deep sea mining might stress out jellyfish, starve them to death, warn scientists   Environmental scientists and biologists often raise concerns about the potential unintended consequences of human activities in the deep sea. The deep ocean is a poorly understood and fragile ecosystem, and disturbances to this environment could have cascading effects on marine life. The expansive underwater communities of the world remain largely unexplored and surprisingly under-studied. However, a recent publication in Nature Communications provides initial insights into how deep pelagic jellyfish respond to stressors associated with global warming and deep-sea mining-induced sediment mounds. Deep-sea drilling is of concern among scientists and environmentalists because of its potential impact on marine ecosystems. Deep-sea mining involves extracting valuable minerals and resources from the ocean floor. The process can cause habitat destruction, change sediment patterns, and rele...

   Brain’s Recycling System: Researchers Unlock the Secret to Neuron Renewal Pioneering Breakthrough in Brain Cell Research Unveiled In a groundbreaking development, scientists at Auburn University have uncovered a crucial process governing the efficient replacement of older proteins in brain cells. This discovery holds profound significance for sustaining effective neural communication and ensuring optimal cognitive function. Innovative Exploration of Protein Recycling in Brain Cells  Published on November 6 in the esteemed journal Frontiers in Cell Development and Biology, the study, titled "Recently Recycled Synaptic Vesicles Use Multi-Cytoskeletal Transport and Differential Presynaptic Capture Probability to Establish a Retrograde Net Flux During ISVE in Central Neurons," delves into the intricate mechanisms of transporting and recycling older proteins within brain cells. Deciphering the Mechanism Behind Protein Replacement in Neurons  Dr. Michael W...

  Revolution in Biology: Semi-Synthetic Yeast Genome Opens New Horizons in Genetic Engineering Synthetic DNA may seem like an idea from science fiction, but it is quickly becoming a reality. In a breakthrough development, researchers have engineered a yeast cell with a genome exceeding 50 percent synthetic content, featuring the world's first fully synthetic chromosome. Although synthetic bacterial and viral genomes had been developed earlier, the advancement of eukaryotic cells—whose genomes were enclosed within a membrane-bound nucleus—represented a significant leap forward. The choice of yeast, particularly baker's yeast (Saccharomyces cerevisiae), was strategic because of its compact 16-chromosome genome and inherent DNA synthesis ability. The Synthetic Yeast Genome Project (Sc2.0) aims not only to synthesize DNA but also to create a "designer" genome for yeast, which intends to depart significantly from nature's blueprint. Senior author and Sc2.0 leader...

    Humans Are Animals, Too For a significant duration, there has been an enduring debate in the realm of animal behavior and cognition. Two main factions have emerged: the exclusivists, who emphasize the distinctions between humans and other animals, and the inclusivists, who focus on the similarities between humans and the rest of the animal kingdom. This debate has ancient origins, with philosophers such as Aristotle and Descartes contending that humans possess unique higher-order cognitive abilities like rational thought and language, while thinkers like Voltaire, Charles Darwin, and David Hume argued that animals exhibit thought and reason, just like humans. Bridging the gap between evolutionary biology and cognitive science, W. Tecumseh Fitch, a cognitive biologist from the University of Vienna, has stressed the importance of studying our more distant animal relatives to gain insights into human cognition. He conveyed this perspective during his keynote speech at the...

14 percent of the US population has experienced prolonged Covid  A research article titled "Long Covid in the United States" published in the journal PLOS One revealed that about 14 percent of the US population has experienced prolonged Covid at some point. The study used data collected from nearly half a million Americans between June 2022 and December 2022 through the US Census Bureau's Household Pulse Survey. Among respondents, 14 percent reported long-term exposure to Covid, with half of them currently experiencing it at the time of the survey. The study also uncovered significant geographic variation in the incidence of prolonged Covid across the United States, ranging from 11 percent in Hawaii to 18 percent in West Virginia. Consistent with previous studies, the results indicate that the incidence rate in the United States is significantly higher in women than in men, as well as in Caucasians compared to black individuals and Asians. Furthermore, the incidence of ...

  Dark Matter is the Biggest unsolved mystery of the universe  The universe is mysterious, yet one in particular stands out among them all. This mystery eludes our senses, unseen, untouchable and unmeasurable. Its presence is known only through its gravitational influence on visible objects around it. It comprises the vast majority of the universe, yet its composition and origin remain uncertain. The revelation of its true nature has the power to reshape our understanding of reality. Scientists refer to this mystery as "dark matter". Dark matter is a theoretical form of matter that does not emit or reflect light but exerts a gravitational pull on ordinary matter. Scientists estimate that dark matter makes up about 85% of the total mass of the universe, yet its fundamental properties and composition are still a mystery. The concept of dark matter was first introduced by Swiss astronomer Fritz Zwicki in the 1930s. He observed that galaxies within the cluster moved at spee...
