Discovery of mitochondrial microprotein opens path to obesity and aging therapies

Biologically, vitamins are absorbed within hours and have instant metabolic effects, such as antioxidants that protect cells or compounds that are building blocks for making hormones. But, many factors impact their efficiency and could keep your body from fully absorbing them. Absorption and effects depend on each individual and what combination of vitamins they take. Gender, age, digestive health, medical conditions, and diet all play a role. One helpful practice to detect deficiencies is to look for the symptoms deficiencies create. Then, look for improvement in your symptoms with supplement intake. You are unlikely to see or feel changes if you do not lack nutrients. If you are chronically tired or see signs of unhealthy nails, hair, or skin, supplements may help as these are indicators that you are lacking nutrients in your diet. If you are unsure, your doctor can order tests to check for deficiencies in your blood.

One major example is protein structure. Methods such as AlphaFold and Boltz-2 have transformed how we generate 3D structural data. Accurate protein structure prediction has been a decades-old challenge, and while there is still work to do on underrepresented protein classes, these models have opened an extraordinary pathway. We have also seen progress in multi-output models. Just over a decade ago (circa 2013), toxicology and property prediction models often focused on one endpoint at a time. Now, multi-output models, especially from methods such as graph neural networks (GNNs) and other deep learning methods, can predict multiple endpoints simultaneously. This allows for transfer learning between related properties. That creates opportunities across ADMET (absorption, distribution, metabolism, excretion, and toxicity) prediction and toxicology. Another exciting area is machine learning potentials. Molecular simulations traditionally rely on fixed mathematical functions to describe molecular interactions, but neural potentials can now replace or augment those functions. They can, in many cases, provide highly accurate simulations and structures at lower computational cost than quantum chemistry. However, its not just down to model architectures. The biggest blind spot behind all of these advances remains careful data curation, annotation, and collection. Open databases for example ChEMBL, PubChem and Chemspider together with data initiatives such as OpenADEMT and OpenBind to name but a few are making notable progress here. We still see some data for example on formulation chemistry often receiving less attention. Its is not just about data scale, but quality that is critical here to. Accessible high quality data sets are the fuel of AI methods. Architecture matters, but high-quality, accessible and abundant data is also absolutely critical.

RAS mutations are one of the most common cancer-causing genetic mutations, and the drug is now being studied in several cancer types. I think it's going to work especially well in tumors that are primarily RAS driven, including colon cancer and lung cancer. It might also work in other cancer types in combination with drugs targeting other genetic mutations, but further research is needed.

Your weight loss plan should keep you healthy and strong as you lose the extra weight. Many plans include a diet low in carbohydrates. Carb cycling is a method of optimizing your carbohydrate intake to meet your needs while dieting, fasting, and working out. When you're carb cycling, you consume carbs to meet your needs on some days and avoid them on other days. The aim of carb cycling is to consume carbohydrates when your body needs them and exclude them at other times. Such strategies in your diet plan can help your weight loss efforts. Carbohydrates, or carbs, are a significant part of the average human diet. Along with proteins and fats, they make up the bulk of your daily meals. Most carbohydrates are broken down by your body into glucose to provide energy for your cells and tissues. Carbohydrates in your diet are of three types — sugars, starches, and fiber. Sugars are simple carbs. Glucose, sugar (sucrose), lactose found in milk, and fructose found in fruits, are naturally occurring sugars. Your body metabolizes these molecules rapidly to yield energy. Starches are complex carbs. They're large molecules that consist of hundreds of molecules of simple sugars joined together. Your body needs to break them down to release energy. Starches are found in bread, potatoes, peas, corn, cereals, and pasta. Fiber is also a complex carbohydrate. Human bodies can't break down these large molecules, so they provide no energy. They're usually excreted as they are in the feces. They add bulk to your meal, so you feel full. Fiber in the diet helps avoid constipation and lowers blood sugar and cholesterol levels. Carbohydrates are an essential part of your diet. A typical diet provides 45% to 65% of its calories from carbohydrates. If you have 2,000 calories a day, you should have about 275 grams of carbohydrates. Always try to choose healthy foods for your carb intake:

Algae are photosynthetic aquatic creatures that grow through the consumption of nutrients, light, and carbon dioxide. They are a diverse group of creatures that include tiny single-celled algae and enormous kelp, as well as seaweed 1. Numerous prokaryotic and eukaryotic algae species are desirable food sources for humans due to their inherent qualities 2,3. Human intake of macroalgae such as seaweed and microalgae like phytoplankton dates back many years. Multicellular macroscopic aquatic plants, or macroalgae, are classified into three taxa: Phaeophyceae, or brown algae, Rhodophyta or red algae, and Chlorophyta or green algae. Microalgae, the unicellular counterpart of macroalgae, are categorized in a broader framework that includes prokaryotic cyanobacteria (blue-green algae), Euglenophyta, and Chlorophyta, which are genetically distinct from one another. The ancient populations of Chad and the Aztec culture were already familiar with the cyanobacteria spirulina, which is currently advertised as a superfood in the West 4. In Burma, Vietnam, and India, other cyanobacteria/microalgae, like Spirogyra and Oedogonium, were eaten as food or as a supplement 4. Seaweed is a staple of daily meals in many Asian and Pacific civilizations, including Korea, Japan, and Indonesia, as well as Hawaii and New Zealand 5.
