AlphaProteo: Google DeepMind’s Breakthrough in Protein Design

In the constantly evolving field of molecular biology, one of the most challenging tasks has been designing proteins that can effectively bind to specific targets, such as viral proteins, cancer markers, or immune system components. These protein binders are crucial tools in drug discovery, disease treatment, diagnostics, and biotechnology. Traditional methods of creating these protein binders are labor-intensive, time-consuming, and often require numerous rounds of optimization. However, recent advances in artificial intelligence (AI) are dramatically accelerating this process.

In September 2024, Neuralink successfully implanted its brain chip into the second human participant as part of its clinical trials, pushing the limits of what brain-computer interfaces can achieve. This implant allows individuals to control devices purely through thoughts.

At the same time, DeepMind’s AlphaProteo has emerged as a groundbreaking AI tool that designs novel proteins to tackle some of biology’s biggest challenges. Unlike previous models like AlphaFold, which predict protein structures, AlphaProteo takes on the more advanced task of creating new protein binders that can tightly latch onto specific molecular targets. This capability could dramatically accelerate drug discovery, diagnostic tools, and even the development of biosensors. For example, in early trials, AlphaProteo has successfully designed binders for the SARS-CoV-2 spike protein and proteins involved in cancer and inflammation, showing binding affinities that were 3 to 300 times stronger than existing methods.

What makes this intersection between biology and AI even more compelling is how these advancements in neural interfaces and protein design reflect a broader shift towards bio-digital integration.

In 2024, advancements in the integration of AI and biology have reached unprecedented levels, driving innovation across fields like drug discovery, personalized medicine, and synthetic biology. Here’s a detailed look at some of the key breakthroughs shaping the landscape this year:

1. AlphaFold3 and RoseTTAFold Diffusion: Next-Generation Protein Design

The 2024 release of AlphaFold3 by Google DeepMind has taken protein structure prediction to a new level by incorporating biomolecular complexes and expanding its predictions to include small molecules and ligands. AlphaFold3 uses a diffusion-based AI model to refine protein structures, much like how AI-generated images are created from rough sketches. This model is particularly accurate in predicting how proteins interact with ligands, with an impressive 76% accuracy rate in experimental tests—well ahead of its competitors.

In parallel, RoseTTAFold Diffusion has also introduced new capabilities, including the ability to design de novo proteins that do not exist in nature. While both systems are still improving in accuracy and application, their advancements are expected to play a crucial role in drug discovery and biopharmaceutical research, potentially cutting down the time needed to design new drugs(

2. Synthetic Biology and Gene Editing

Another major area of progress in 2024 has been in synthetic biology, particularly in the field of gene editing. CRISPR-Cas9 and other genetic engineering tools have been refined for more precise DNA repair and gene editing. Companies like Graphite Bio are using these tools to fix genetic mutations at an unprecedented level of precision, opening doors for potentially curative treatments for genetic diseases. This method, known as homology-directed repair, taps into the body’s natural DNA repair mechanisms to correct faulty genes.

In addition, innovations in predictive off-target assessments, such as those developed by SeQure Dx, are improving the safety of gene editing by identifying unintended edits and mitigating risks. These advancements are particularly important for ensuring that gene therapies are safe and effective before they are applied to human patients(

3. Single-Cell Sequencing and Metagenomics

Technologies like single-cell sequencing have reached new heights in 2024, offering unprecedented resolution at the cellular level. This allows researchers to study cellular heterogeneity, which is especially valuable in cancer research. By analyzing individual cells within a tumor, researchers can identify which cells are resistant to treatment, guiding more effective therapeutic strategies.

Meanwhile, metagenomics is providing deep insights into microbial communities, both in human health and environmental contexts. This technique helps analyze the microbiome to understand how microbial populations contribute to diseases, offering new avenues for treatments that target the microbiome directly(

A Game-Changer in Protein Design

Proteins are fundamental to virtually every process in living organisms. These molecular machines perform a vast array of functions, from catalyzing metabolic reactions to replicating DNA. What makes proteins so versatile is their ability to fold into complex three-dimensional shapes, allowing them to interact with other molecules. Protein binders, which tightly attach to specific target molecules, are essential in modulating these interactions and are frequently used in drug development, immunotherapies, and diagnostic tools.

The conventional process for designing protein binders is slow and relies heavily on trial and error. Scientists often have to sift through large libraries of protein sequences, testing each candidate in the lab to see which ones work best. AlphaProteo changes this paradigm by harnessing the power of deep learning to predict which protein sequences will effectively bind to a target molecule, drastically reducing the time and cost associated with traditional methods.

How AlphaProteo Works

AlphaProteo is based on the same deep learning principles that made its predecessor, AlphaFold, a groundbreaking tool for protein structure prediction. However, while AlphaFold focuses on predicting the structure of existing proteins, AlphaProteo takes a step further by designing entirely new proteins.

How AlphaProteo Works: A Deep Dive into AI-Driven Protein Design

AlphaProteo represents a leap forward in AI-driven protein design, building on the deep learning techniques that powered its predecessor, AlphaFold.

While AlphaFold revolutionized the field by predicting protein structures with unprecedented accuracy, AlphaProteo goes further, creating entirely new proteins designed to solve specific biological challenges.

AlphaProteo’s underlying architecture is a sophisticated combination of a generative model trained on large datasets of protein structures, including those from the Protein Data Bank (PDB), and millions of predicted structures generated by AlphaFold. This enables AlphaProteo to not only predict how proteins fold but also to design new proteins that can interact with specific molecular targets at a detailed, molecular level.

This diagram showcases AlphaProteo’s workflow, where protein binders are designed, filtered, and experimentally validated

Generator: AlphaProteo’s machine learning-based model generates numerous potential protein binders, leveraging large datasets such as those from the Protein Data Bank (PDB) and AlphaFold predictions.

Filter: A critical component that scores these generated binders based on their likelihood of successful binding to the target protein, effectively reducing the number of designs that need to be tested in the lab.

Experiment: This step involves testing the filtered designs in a lab to confirm which binders effectively interact with the target protein.

AlphaProteo designs binders that specifically target key hotspot residues (in yellow) on the surface of a protein. The blue section represents the designed binder, which is modeled to interact precisely with the highlighted hotspots on the target protein.

For the C part of the image; it shows the 3D models of the target proteins used in AlphaProteo’s experiments. These include therapeutically significant proteins involved in various biological processes such as immune response, viral infections, and cancer progression.

High Binding Affinity: AlphaProteo excels in designing protein binders with high affinity for their targets, surpassing traditional methods that often require multiple rounds of lab-based optimization. It generates protein binders that attach tightly to their intended targets, significantly improving their efficacy in applications such as drug development and diagnostics. For example, its binders for VEGF-A, a protein associated with cancer, showed binding affinities up to 300 times stronger than existing methods.

Targeting Diverse Proteins: AlphaProteo can design binders for a wide range of proteins involved in critical biological processes, including those linked to viral infections, cancer, inflammation, and autoimmune diseases. It has been particularly successful in designing binders for targets like the SARS-CoV-2 spike protein, essential for COVID-19 infection, and the cancer-related protein VEGF-A, which is crucial in therapies for diabetic retinopathy.

Experimental Success Rates: One of AlphaProteo’s most impressive features is its high experimental success rate. In laboratory tests, the system’s designed binders demonstrated high success in binding to target proteins, reducing the number of experimental rounds typically required. In tests on the viral protein BHRF1, AlphaProteo’s designs had an 88% success rate, a significant improvement over previous methods.

Optimization-Free Design: Unlike traditional approaches, which often require several rounds of optimization to improve binding affinity, AlphaProteo is able to generate binders with strong binding properties from the outset. For certain challenging targets, such as the cancer-associated protein TrkA, AlphaProteo produced binders that outperformed those developed through extensive experimental optimization.

Man but the notes on that post really are just tumblr showing they have no idea how anything works.

"report to your local animal abuse people not to cops" local animal abuse people would be animal control. Animal control officers are cops.

"rabies is treatable if you go to the doctor right after the bite" rabies is PREVENTABLE, not treatable. There is no cure for rabies. If you suspect you came into contact with a rabid animal, you need to get a series of rabies vaccinations to prevent the virus from taking over your body. This is not a treatment and it only works if you go right away. If you show any symptoms of rabies it is too late.

"rabies is fatal in animals but treatable in humans" rabies has a 100% fatality rate and is not considered a survivable disease at this point in time. If you contract rabies YOU WILL DIE. The "treatment" in humans is called the Milwaukee Protocol, only 14% of people survive it, and it leaves you with massive brain damage and effectively turns you into a vegetable. You do not return to a normal life afterwards. Very few people who have undergone this process are capable of doing more than laying in a hospital bed and eating and breathing through tubes. To my knowledge only one person was able to live a semi-normal life after years and years of ongoing therapy and was not expected to have made it even through her first year after treatment.

I cannot stress enough how rabies is unlike any other disease you may be thinking of. It's required on a federal level in this country to vaccinate pretty much any domestic animal that comes into contact with wildlife for one reason and one reason only: it is not considered possible to cure rabies and the spread of disease would threaten all mammalian life including our own if allowed to continue to propagate.

Ayurveda Management for Stroke Paralysis

Stroke Paralysis represents a prevalent medical emergency that can occur suddenly, making it a global health concern and the third most prevalent cause of mortality across the world. Stroke, also medically referred to as CVA (Cardiovascular Accident), and is characterized by the abrupt demise of brain cells due to insufficient oxygen supply caused by the occlusion of a brain artery. This condition stands as the leading cause of adult disability, impacting individuals’ quality of life significantly.

In the context of Ayurveda, stroke can be linked to the ancient concept of “Pakshaghata,” underscoring the timelessness of this ailment in human history.

Stroke Paralysis Symptoms

Sudden Numbness or Weakness: One of the most recognizable signs is the sudden onset of numbness or weakness, usually on one side of the body. This can affect the face, arm, or leg.

Trouble Speaking: Stroke can impair speech and language abilities. You may experience slurred speech, difficulty finding words, or an inability to speak at all.

Confusion: Stroke can lead to confusion, making it challenging to understand or process information. This may be accompanied by disorientation.

Trouble Walking: People having a stroke often have difficulty walking or maintaining balance. They may stumble, feel unsteady, or even collapse.

Severe Headache: A sudden, severe headache, often described as the “worst headache of your life,” can be a symptom of a stroke, especially if it occurs abruptly.

Vision Problems: A stroke can cause vision problems, such as blurred vision, double vision, or a sudden loss of vision in one or both eyes.

Dizziness or Loss of Coordination: Feeling dizzy or experiencing a loss of coordination and control over your movements can be indicative of a stroke.

Facial Drooping: One side of the face may droop or become asymmetrical, particularly around the mouth and eye.

Difficulty Swallowing: A stroke can affect the ability to swallow, leading to choking or coughing while eating or drinking.

Loss of Consciousness: In severe cases, a stroke can cause a loss of consciousness or fainting.

Causes of Stroke/ Paralysis

Stroke paralysis can happen anytime and it is the third leading cause of death estimated. Damage to the central nervous system is the main cause of paralysis and the chances of stroke in today’s fast lifestyle have been more than before.

Stroke paralysis can be due to various reasons:

Cerebrovascular accident (Ischaemic or hemorrhagic)

Damage to the spinal cord – A fall or heavy shock in the spinal cord can be fatal. It can, in turn, affect the central nervous system and result in paralysis.

Trauma with nerve injury – A trauma and subsequent nerve injury can lead to defects in the nervous system. This will adversely affect signal transmission from the brain and lead to stroke/ paralysis.

Multiple sclerosis – This problem occurs when our immune system attacks the protective sheath called Myelin on the nerve fibers. The communication between brain and body parts is impaired due to it and leads to paralysis.

Muscular Dystrophy – Muscular Dystrophy is caused by a group of diseases. Abnormal gene mutation affects the production of proteins required for the strengthening of muscles, thus causing paralysis.

Brain damage – Brain damage due to high Blood Pressure, physical damage, or other physical conditions can be fatal. It can drain the brain of blood and result in a stroke.

Exposure to toxins and poisons – Persons working in a toxic environment can fall prey to paralysis due to pollutants, in unacceptable proportions, entering the body.

Metabolic disorders – Several Metabolic disorders are also found to be the reason for paralysis.

Inherited demyelinating disease – Hereditary abnormalities may cause demyelination of the central nervous system resulting in stroke or paralysis.

Poliomyelitis – The virus is the cause of Poliomyelitis, which is simply called Polio and is also a reason for paralysis.

Ayurvedic treatment for Stroke Paralysis

According to Ayurveda, the main line of treatment for Paralysis is regulating the flow of Prana Vayu. This is done by following Ayurveda therapies and has to be carried out in all stages of Paralysis depending on the general condition of the patient. In the realm of Ayurveda, the management of stroke-related paralysis often involves Panchakarma, a set of cleansing therapies. These therapies for paralysis patients encompass a range of techniques:

Snehana (Oleation) Treatment: This involves applications like massages, Kayaseka, Shirodhara, Shirobasti, Pichu, and more, using medicated oils. These treatments are administered over a period of 7 to 21 days. The application of symptom-specific medicated oils, followed by medicated fomentation, serves to enhance circulation, strengthen muscles, and fortify nerves.

Virechana (Purgation): Virechana therapy is employed to boost metabolism, alleviate constipation, fortify the gastrointestinal system, and enhance nerve function in the affected areas.

Basti (Medicated Enema): Basti therapy, offered in various forms such as Matra Basti, Anuvasana Basti, and Nirooha Basti, extends for a duration of 8 to 32 days. Medicated enema treatments contribute to nourishing, strengthening, and stabilizing overall bodily functions. These treatments assume a pivotal role in the recovery of stroke patients, particularly when sought within three months of the paralytic episode.

Nasya Karma: Administered for 7 to 9 days, Nasya therapy focuses on strengthening muscles, nerves, and circulation above the shoulder area.

Abhyangam: Abhyanga is a full-body Ayurveda massage technique that relaxes the muscles and soothes the nerves

Pizhichil: Pizhichil Ayurvedic Treatment includes massaging with warm oil and therefore can stimulate the nerves and muscles.

Diet and Lifestyle in Stroke Paralysis

Avoid excessive use of spicy, salty, oily/ fatty foods.

Include black gram, horse gram, onion, garlic, ginger, radish, ash gourd, green gram, etc. in your regular diet.

Intake more fruits like pomegranate, grape, or papaya.

Intake of low-fat and high-fiber diets as advised by a physician.

Control Diabetes mellitus, hypertension, and heart diseases.

Practice Yoga and regular exercises.

Avoid alcohol consumption and smoking.

Avoid discontinuing any regular medicines without a doctor’s advice.
