Can AI Really Be Your Therapist? What the Science Says About AI and Mental Health A research-driven Next Horizon longread on depression detection, therapy chatbots, empathy, crisis safety, and a question that is moving from science fiction into everyday life: how much of a psychologist's work can AI really do? Editorial position The article should not argue that AI is either a miracle therapist or a dangerous toy. The evidence is more interesting: specialized systems can produce measurable benefits for some people, while general-purpose chatbots still fail in exactly the situations where human clinical judgment matters most. AI can already listen, respond, and guide structured mental health exercises — but therapy is much more than a conversation.

Your DNA May Change Your Prescription How AI and Pharmacogenomics Are Making Medicine Personal Longread • Updated for 2026 Pharmacogenomics uses genetic information to understand why the same medicine can work differently from one person to another. AI could make those decisions more precise by combining DNA with other clinical data. Medical note: this article explains research and clinical practice in general terms. A pharmacogenomic result is not a reason to start, stop, or change a medication without a qualified clinician.

AI Assistants for Doctors in 2026: Can Artificial Intelligence Replace Physicians? The most useful medical AI systems do not look like white-coated robots. They listen, read, summarize, notice patterns, prepare decisions — and quietly take over some of the work that keeps doctors away from patients.

The Genome Is 3 Billion Letters Long. AI Is Learning Which Ones Matter Artificial intelligence is giving scientists new ways to interpret DNA, identify meaningful genetic variants, and uncover patterns hidden inside the human genome. Sequencing the human genome is no longer the impossible part. Understanding it is. Today, a DNA sequencer can turn a biological sample into an enormous digital file made of four letters: A, C, G and T. Producing that sequence is no longer the hardest part. The harder question is what it means. Which changes are harmless? Which alter a protein? Which change when a gene switches on? Which matter only in one tissue? And which may raise disease risk years before anything appears on a scan or blood test? This is the kind of problem artificial intelligence is unusually well suited to. Genomics contains vast amounts of data, patterns that can stretch across long sequences, and more possible genetic changes than researchers could ever test one by one i...

AI in Radiology: Can Artificial Intelligence Read Medical Scans Better Than Doctors? AI is becoming a second set of eyes in radiology, helping doctors detect suspicious findings, prioritize urgent scans and measure changes more consistently. Imagine an emergency department at 2 a.m. A new head CT lands in a queue that is already full. Somewhere in those hundreds of images may be a small brain bleed that cannot wait. The radiologist still has to make the call—but software can scan the study first, flag a suspicious area and move the case closer to the front. That is AI in radiology in one of its most useful forms: not a robot doctor, but a fast second set of eyes.

Can AI Detect Disease Before We Feel Sick? How Artificial Intelligence Is Changing Early Diagnosis in 2026 Artificial intelligence is helping medicine detect weak signals of disease earlier — from scans and blood biomarkers to wearable data and retinal images. A disease can be present long before it feels like one. A tiny tumor may grow silently. An abnormal heart rhythm can appear for twenty minutes and vanish before a clinic ECG is recorded. Changes linked to neurodegenerative disease may begin years before severe symptoms. By the time the body finally sends an obvious warning, the underlying biology may have been changing for a long time. That is why early detection matters — and why it is difficult. Early disease rarely arrives with a bright red label saying, ‘Here I am.’ The clues may be an almost invisible shadow on a mammogram, a tiny amount of tumor DNA in blood, a change in retinal vessels, or a brief rhythm disturbance buried inside weeks of wearable data. Each c...
