Recent research illustrates how RNA molecules’ chemical characteristics might have played a crucial role in the development of complex life forms. How did complex life manage to evolve on the early, inhospitable Earth? Initially, ribonucleic acid (RNA) must have existed to carry the first genetic information. For these biomolecules to build-up complexity in their sequences, they [...]
By harnessing the power of composite polymer particles adorned with gold nanoparticles, a group of researchers have delivered a more accurate means of testing for infectious diseases. Details of their research was published in the journal Langmuir ("Gold Nanoparticle-Decorated Polymer (GNDP) Particles for High-Optical-Density Immunoassay Probes"). The COVID-19 pandemic reinforced the need for fast and reliable infectious [...]
Researchers have developed micromaterials made up only of proteins, capable of delivering over an extended period of time nanoparticles that attack specific cancer cells and destroy them. The micromaterials mimic natural secretory granules found in the endocrine system and were proven effective in mouse models of colorectal cancer. The study is published in the journal Advanced Science. [...]
Dementia is a major health issue worldwide in the 21st century, impacting over 50 million people globally. This figure is expected to soar to 152 million by 2050, as the global population ages. Alzheimer’s disease (AD) is the leading type of dementia, responsible for 60–80% of all dementia cases. Research on AD identifies two primary pathological [...]
Viruses need hosts. Whether it's measles, the flu or coronavirus, viral pathogens cannot multiply or infect other organisms without the assistance of their hosts' cellular infrastructure. However, humans are not the only ones affected by viruses: animals, plants and even microorganisms can all serve as hosts. Viruses that use bacteria as host cells are called bacteriophages [...]
Over the past few years, hardware manufacturers have developed technologies that ought to make it possible for companies and governmental organizations to process sensitive data securely using shared cloud computing resources. Known as confidential computing, this approach protects sensitive data while it is being processed by isolating it in an area that is impenetrable [...]
It’s been more than five decades since Dustin Hoffman’s character in “The Graduate” was offered a kernel of wisdom about the path to prosperity. “Plastics,” he’s told by Mr. McGuire, the starched corporate executive who offers the advice. “There’s a great future in plastics.” Plastics have indeed been a game changer for humanity, and the [...]
KEY POINTS Human-AI interactions are currently asymmetrical, lacking continuity and depth. AI evolution may lead to more sustained, contextually rich user relationships. Balancing asymmetry and connection requires design advocacy and technological adaptations. As artificial intelligence (AI) continues to advance at an unprecedented pace—flanking humanity on almost every side—it's becoming increasingly important to take a look at [...]
A new study led by researchers from University College London (UCL) and the University of Innsbruck reveals that individuals who use e-cigarettes, despite having a limited history of smoking, undergo similar changes in DNA within certain cells of the cheek, comparable to those observed in smokers. This study is an incremental step in helping researchers build a deeper understanding of [...]
Iron levels and inflammation after COVID-19 infection are linked to long COVID, with research indicating that early intervention in iron regulation could mitigate long-term symptoms. Problems with iron levels in the blood and the body’s ability to regulate this important nutrient as a result of SARS-CoV-2 infection could be a key trigger for long COVID, new research has [...]
