A study of rockfish longevity has revealed a set of genes controlling their aging process, leading to the discovery of a previously unappreciated group of genes associated with extended lifespan in humans. The findings show that the same pathways that promote longevity in rockfish also promote longevity in humans. The study identified two major metabolic systems that regulate lifespan in rockfish: the insulin-signaling pathway, which prior research has shown plays a major role in regulating the lifespan of many different animals, and the previously unappreciated flavonoid metabolism pathway. These results provide insights into how to prevent or delay common human diseases of old age.

Did you know that adults catch more than 150 colds throughout their lives, and that a single family of viruses causes 30 to 50% of all colds? Understanding the complex relationship between viruses and our immune systems is not only fascinating, but also highly relevant to our daily lives. By reading about pleconaril, rhinovirus, and CRISPR, you'll learn about the science behind vaccines and antiviral drugs, and how they could help us tackle the common cold. But beyond that, exploring this topic will help you appreciate the incredible complexity and resilience of our immune systems, and the importance of maintaining our health. So grab a cup of tea and your favorite notebook, and get ready to dive into the fascinating world of viruses and immune systems!

Humans and viruses have been locked in an evolutionary race for survival, with both constantly adapting to changing environments. But while humans have evolved relatively slowly over millions of years, viruses can mutate much more quickly. This is because of their small size, short generation times, and high replication rates. One key reason for this rapid mutation is the lack of DNA repair mechanisms in viruses. Unlike humans, whose cells have a variety of enzymes and pathways that help fix errors in DNA, viruses rely on the host cell's machinery to replicate their genetic material. This means that errors in viral DNA are not always corrected and can accumulate over time, leading to rapid evolution. Another reason for the high mutation rates in viruses is the high rate of recombination, in which genetic information from different viral strains is mixed together. This can create new combinations of genes that can give the virus an advantage in evading the host's immune system. These high mutation rates in viruses have important implications for human health. For example, influenza viruses are able to quickly evolve new strains that can evade our immune systems, making it difficult to create a universal flu vaccine. Similarly, HIV can mutate quickly to become resistant to antiviral drugs. But don't let the challenges posed by the rapid evolution of viruses discourage you! In fact, this presents an opportunity for you to delve deeper into the fascinating field of genetics and evolution. By learning more about how viruses mutate and evolve, you can gain a better understanding of the underlying mechanisms behind genetic change. And who knows, maybe one day you could even be part of a team that develops a groundbreaking new treatment for viral infections. Keep exploring and learning, and the possibilities are endless!

DNA is a molecule that holds the secrets of life within its code, and it's waiting for you to explore it! This amazing molecule determines our traits, from our physical appearance to our personalities, and it can also tell us about our ancestry, our risk of diseases, and much more. Leading academics in the field of genetics, such as James Watson and Francis Crick, made major contributions to our understanding of DNA by discovering its structure and how it stores and transfers genetic information. Watson and Crick's discovery of the double helix structure of DNA was a major turning point in the field of genetics and opened up new avenues for scientific research. In the early 1990s, the Human Genome Project was launched to map all of the genes in human DNA. This project was a huge success and has had a profound impact on the field of genetics. It allowed scientists to identify specific genes that are associated with different diseases, such as cancer, and has paved the way for new treatments and cures. One of the most fascinating things about DNA is that every person's DNA is 99.9% identical to every other person's DNA. It's the remaining 0.1% that makes each of us unique! Our DNA also contains fascinating stories about our ancestors and their migrations. For example, DNA testing can tell us where our ancestors came from and how they migrated across the world. This is known as genetic genealogy, and it's an exciting field that combines genetics and history. Another fascinating aspect of DNA is its role in evolution. Charles Darwin's theory of evolution by natural selection states that species change over time through the process of natural selection. This process occurs because certain traits that provide an advantage in survival and reproduction become more common in a population over time. DNA mutations can lead to changes in traits, and over many generations, these changes can accumulate and result in new species. By exploring the world of DNA, you will not only deepen your understanding of genetics and biology, but also gain a new appreciation for the complexities and wonders of life. So go ahead, unlock the secrets of life with the power of DNA!

Get ready to revolutionize the way we treat cancer and age-related diseases! A new company, GlioQuell, co-founded by Dr. Kambiz Alavian from the Department of Brain Sciences, is developing a cutting-edge approach to target the powerhouses of cancer cells - the mitochondria. By reducing the efficiency of these structures, GlioQuell aims to turn off the cancer cells' energy supply and treat one of the most aggressive forms of cancer - glioblastoma.

Mitochondria are often referred to as the powerhouses of the cell and for good reason. These tiny organelles are responsible for producing the energy that our cells need to function. In this write-up, we'll explore the magic of mitochondria and why they are so important to our health and well-being. Did you know that mitochondria are sometimes referred to as the "second genome"? This is because they have their own DNA and can replicate independently of the cell's nucleus. This discovery, made by Dr. Douglas C. Wallace in the late 1970s, revolutionized our understanding of cellular biology. Another interesting fact about mitochondria is that they are thought to have originated from a symbiotic relationship between early cells and primitive bacteria. Over time, the two organisms evolved together to form the cells that make up our bodies today. This theory, known as the endosymbiotic theory, was first proposed by Dr. Lynn Margulis in the 1960s. So, what exactly do mitochondria do? Well, they are responsible for producing energy in the form of ATP (adenosine triphosphate) through a process called cellular respiration. This energy is then used by our cells to carry out all of their functions, from moving and growing, to repairing and reproducing. It's important to note that our cells can't survive without energy, and without mitochondria, we wouldn't be able to produce enough energy to support our bodies. This is why mitochondria are so critical to our health and well-being. By learning more about the magic of mitochondria, you'll gain a deeper understanding of cellular biology and the role that these tiny organelles play in our lives. So, get reading, reflecting, and exploring!

Our sense of smell plays a significant role in our ability to process flavor, and yet it's often overlooked as a key component of taste. Smell molecules stimulate our olfactory sensory neurons, which then send information to the brain about the odor and associate feelings, moods, and emotions with that odor for future reference. The brain can also categorize information as a particular odor, allowing us to differentiate between different smells. People with a healthy working sense of smell can detect anywhere between 10,000 to more than a trillion different odors. Taste, on the other hand, comes from taste receptors on our tongues and in our mouths and is limited to the basics of salty, sweet, bitter, sour, and umami. Together, smell and taste work to bring nuance to what we eat. By understanding the power of our sense of smell, we can unlock a world of complex and delightful flavors.

The world's leading scientists were stunned when a Chinese scientist claimed to have created the world's first gene-edited babies. This article explores the latest developments in the field of gene editing in China.

As we grow older, our bodies undergo many changes, including changes in our metabolism. Metabolism refers to the chemical processes that occur in our bodies to maintain life. These processes are essential for providing energy, building and repairing tissues, and eliminating waste products. As we age, our metabolic pathways can become altered, leading to various age-related diseases and conditions. One example of a metabolic pathway that is affected by aging is the mitochondrial electron transport chain (ETC). The ETC is responsible for producing ATP, the primary source of energy for our cells. As we age, the function of the ETC can become impaired, leading to a decrease in ATP production and an increase in oxidative stress. This can contribute to age-related diseases such as Alzheimer's disease, Parkinson's disease, and diabetes. Another example is the mTOR (mechanistic target of rapamycin) pathway, which regulates cellular growth and metabolism. Studies have shown that inhibiting the mTOR pathway can increase lifespan in various model organisms, including mice. This has led to increased interest in developing drugs that target this pathway as a potential anti-aging strategy. One of the leading academics in this field is Dr. David Sinclair, a Professor of Genetics at Harvard Medical School. Dr. Sinclair's research has focused on the role of metabolism in aging and age-related diseases, and he has made significant contributions to the field. For example, his research has shown that supplementing with NAD+, a molecule involved in energy metabolism, can improve various aspects of aging in mice. Another leading academic in this field is Dr. Valter Longo, a Professor of Gerontology and Biological Science at the University of Southern California. Dr. Longo's research has focused on the role of fasting and caloric restriction in aging and age-related diseases. His work has shown that periodic fasting can have a range of health benefits, including improving insulin sensitivity and reducing inflammation. In conclusion, the study of metabolic pathways in aging is a fascinating and rapidly growing field. By understanding the complex interplay between metabolism and aging, we can better understand the underlying causes of age-related diseases and conditions. Students who are interested in this topic can continue to explore it through reading and research, or by pursuing their own experiments and projects. With the right tools and resources, they can make meaningful contributions to this exciting field and help improve our understanding of aging and metabolic pathways.

Have you ever wondered why a black eye turns blue, then green, then yellow, and finally brown before disappearing? It's all because of your hemoglobin, the compound in red blood cells that brings oxygen to your body. When you get hit, the blow crushes tiny blood vessels called capillaries, and red blood cells ooze out of the broken capillaries into the surrounding tissue. From the outside of your skin, this mass of cells looks bluish-black, which is where we get the term, "black and blue". Learning about hemoglobin and how it works in your body can be fascinating and practical knowledge that can help you understand how your body works. It's an example of how exploring academic topics through reading, reflection, and writing can inspire you to learn more about the world around you.

Did you know that selecting the embryo with the lowest risk for a given disease can cut the risk for that disease by almost half? This is particularly true for disorders such as schizophrenia and Crohn’s disease. However, the selection process may not lead to significant improvements in non-disease traits such as intelligence. Moreover, the use of preimplantation genetic screening (PES) raises concerns about psychological well-being, social values, and ethics. Learn more about the potential benefits and risks of PES, and how it may impact our society and individuality.

HIV, the virus that causes AIDS, is a master of disguise. It can change its outer coat of proteins frequently, making it hard for the immune system to recognise and destroy it. HIV targets Helper T cells, which act as the air traffic controllers of the immune system, coordinating the efforts of other immune cells. If Helper T cells disappear, the whole immune system would have trouble fighting not just HIV but many other illnesses as well. Boosting the immune system against HIV requires getting the Helper T cells back in control. Learning about the immune system and how it works can help you understand how HIV affects the body and how to boost your immune system against it. By exploring this topic through reading, reflection, writing and self-directed projects, you can gain a deeper understanding of the immune system and how to protect yourself from harmful intruders like viruses and bacteria.
