New research has identified gold-based compounds that could treat multidrug-resistant "superbugs", with some effectiveness against several bacteria. Antibiotic resistance is a global public health threat, and the development of new antibiotics has stalled. Gold metalloantibiotics, compounds with a gold ion at their core, could be a promising new approach. Dr. Sara M. Soto Gonzalez and colleagues studied the activity of 19 gold complexes against a range of multidrug-resistant bacteria isolated from patients. The gold compounds were effective against at least one bacterial species studied, with some displaying potent activity against several multidrug-resistant bacteria.

Did you know that spending just a few weeks in space can lead to a 20% loss of muscle mass? That's because in microgravity, astronauts don't need to use their muscles as much to stay upright or move around. This lack of exercise leads to a breakdown in muscle tissue and a loss of strength. But it's not just astronauts who are affected by muscle degradation. People on bed rest, those with certain medical conditions, and even the elderly can experience a loss of muscle mass and function. So what's happening on a cellular level? When muscles aren't used, they begin to break down proteins for energy. This process, called protein degradation, can lead to the loss of muscle mass and function. But don't worry, researchers are working hard to find ways to combat muscle degradation in space and on Earth. One approach is to use exercise machines that simulate gravity, which have been shown to maintain muscle mass in astronauts. Other research has focused on using drugs to block the protein degradation process and promote muscle growth. Leading academics in the field of muscle degradation include Dr. Robert Fitts, a professor of biology at Marquette University, who has researched the effects of microgravity on muscle mass and function. Dr. Lori Ploutz-Snyder, a professor at the University of Michigan, has also studied muscle atrophy and is working on developing exercise programs to prevent it. Overall, muscle degradation is a serious concern for both astronauts and people on Earth. By learning more about the causes and potential solutions, we can work towards maintaining healthy muscles and preventing muscle loss.

Researchers have identified lipid differences in patients with alcohol-related liver disease that could lead to earlier detection and new treatments.

So grab a cup of tea and your favorite notebook, and get ready to dive into the fascinating world of viruses and immune systems!

An interdisciplinary UCLA research team has developed a tiny implantable device called SymphNode, which has been shown to be able to drive tumours into remission, eliminate metastasis, and prevent the growth of new tumours, resulting in longer survival in mice. This groundbreaking technology may decrease the risk of cancer returning, making it a potential addition to chemotherapy or other first-step treatments for a variety of cancers.

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!

Artificial Intelligence (AI) is transforming the healthcare industry in ways we never imagined. AI has the potential to revolutionize the way we diagnose, treat, and prevent diseases. With the help of AI, medical professionals can now analyze large amounts of data in seconds, making the process of diagnosing and treating patients much more efficient. Leading academics such as Dr. Eric Topol, a cardiologist and digital health pioneer, have been working on incorporating AI into healthcare for years. For example, Dr. Topol has been working on developing AI algorithms that can help diagnose diseases from scans and images, reducing the need for invasive procedures. He has also been studying the use of AI in personalized medicine, where AI can help predict the best treatment for a patient based on their specific genetic makeup. Statistics show that AI is already having a positive impact on healthcare. In 2019, researchers used AI to diagnose skin cancer with accuracy comparable to human dermatologists. Another study found that AI could help detect breast cancer up to five years before a traditional mammogram. These are just a few examples of how AI is changing the face of healthcare. AI is also helping healthcare professionals work more efficiently. For example, AI algorithms can quickly analyze medical records and help doctors identify patients who need immediate attention. This saves time and reduces the risk of missing critical information.

China's updated regulations on gene editing in humans may not be enough to prevent regulatory negligence and ethical concerns, warns Dr Joy Zhang of Kent University. The regulations set requirements for ethical approval, supervision, and inspection, but experts worry they may not apply to the private sector. Gene editing is a controversial technique that could correct many inherited diseases, but raises the possibility of permanent changes to a person's genetic make-up. 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.

Scientists sequence Beethoven's genome from locks of hair, revealing new insights into his health and ancestry. The study, led by Cambridge University and other institutions, uncovers genetic risk factors for liver disease and an infection with Hepatitis B virus. Beethoven's hearing loss remains a mystery, but his genomic data rules out coeliac disease and lactose intolerance as potential causes. The study sheds light on the composer's health problems, including chronic gastrointestinal complaints and a severe liver disease that likely contributed to his death at age 56.
