The history of life on Earth spans billions of years, from the formation of our planet to the evolution of diverse life forms. This epic tale of biological evolution is intertwined with geological events, environmental changes, extinction events, and the emergence of complex organisms. The story of life on Earth is a testament to the … Read more
Hvidovre Hospital has the world’s first prototype of a sensor capable of detecting errors in MRI scans using laser light and gas. The new sensor, developed by a young researcher at the University of Copenhagen and Hvidovre Hospital, can thereby do what is impossible for current electrical sensors—and hopefully pave the way for MRI scans … Read more
Physiology is the branch of biology that focuses on the study of the functions and processes of living organisms and their parts. It encompasses various levels of organization, from cells and tissues to organs and organ systems, and examines how these components work together to maintain homeostasis and support life. In this discussion, we’ll delve … Read more
Human anatomy, the study of the body’s structure and organization, provides a foundational framework for understanding the complex organization and functions of the human body. From the microscopic level of cells and tissues to the macroscopic level of organs and organ systems, human anatomy elucidates the anatomical structures, physiological processes, and interconnected systems that sustain … Read more
In 1991, German tourists discovered, in the Eastern Italian Alps, a human body that was later determined to be the oldest naturally preserved ice mummy, known as Otzi or the Iceman. Now, researchers reporting in the journal Current Biology on July 12 who have conducted the first in-depth analysis of the Iceman’s stomach contents offer … Read more
Scientists from multiple institutions in North America have achieved a significant milestone in unraveling the mechanisms underlying Ebola virus replication within human cells. This breakthrough marks a crucial advancement towards the creation of novel treatments aimed at tackling this formidable and often fatal illness. The study, published in PLOS Biology, involved a team of pharmacologists … Read more
Ötzi the Iceman, also known as the Similaun Man, is one of the most remarkable archaeological discoveries of the 20th century. He is a well-preserved natural mummy of a man who lived during the Copper Age, approximately 5,300 years ago. Ötzi was discovered by hikers in the Ötztal Alps along the border between Austria and … Read more
In a groundbreaking excavation at the Boncuklu Tarla site in southeastern Türkiye, archaeologists have unearthed a treasure trove of human history dating back an astonishing 11,000 years. The discovery? Evidence of body perforation, shedding new light on the rituals and practices of early sedentary communities. The findings, meticulously analyzed by a team from Ankara University, … Read more
A new, greener, and cheaper method to accelerate chemical reactions has been developed by scientists at King’s College London in collaboration with the University of Barcelona and ETH Zurich. Instead of using polluting and expensive metal-based catalysts, the team proved that electric fields can catalyze reactions to produce chemical compounds. Building on previous research published … Read more
Queensland researchers have become the first in Australia to use human stem cells to generate fully functioning skin tissue in a laboratory, a significant step toward better treatments for severe burns and wounds. The skin tissue, produced by The University of Queensland’s Frazer Institute and Metro North Health’s Herston Biofabrication Institute, can develop hair follicles … Read more
Researchers from Imperial College London’s Department of Materials have crafted a cutting-edge portable maser, shrinking the technology to fit within the confines of a compact shoebox. Imperial College London had previously pioneered room-temperature solid-state masers in 2012, a milestone that underscored their capability to amplify faint electrical signals with high-frequency stability. This innovation is particularly … Read more
The human body is colonized by a variety of different microorganisms such as bacteria, yeasts and fungi. All these microbial co-inhabitants—known as the microbiome or microbiota—are important for our health: For example, the microbiome in the gut supports digestion and helps to make nutrients available. Although certain groups of bacteria dominate the human gut microbiome, … Read more
Hydrogels have emerged as incredibly versatile biomaterials, revolutionizing various biomedical applications. These water-swollen molecular networks offer a unique opportunity to mimic the mechanical and chemical properties of diverse organs and tissues, facilitating seamless integration within the human body without causing harm, even to the most delicate anatomical structures. In clinical practice, hydrogels are already making … Read more
University of Pittsburgh School of Medicine researchers discovered a molecular mechanism by which excessive dietary protein could increase atherosclerosis risk. The findings were published in Nature Metabolism. The study, which combined small human trials with experiments in mice and cells in a Petri dish, showed that consuming over 22% of dietary calories from protein can … Read more
New research by Northeastern scientists questions the long-held belief that the connective tissues that give us mechanical strength, such as tendons, ligaments, bones and skin, form in the human body by cells coming together. Instead, our tissues are more likely formed by cells pulling apart, according to the research published today in Matter. It’s long … Read more
Imagine adjusting your clothes to beat the summer heat or winter chill just by changing the temperature of your clothes, on the go. Wearable thermal control devices promise just that, offering portable personal thermal comfort. Not only that, but these devices also have other applications such as providing temperature feedback in virtual and augmented reality … Read more
