Imagine you’re 90 years old, a grandmother of three and your husband is also elderly and ailing. You need help with almost everything, getting out of a chair, going to the bathroom, getting dressed, eating and remembering your medications. Despite advances in life expectancy, ageing has not been kind, and you feel like a burden to your husband and the healthcare professionals who care for you. Now, imagine being offered a robot that could help with many of these things – from walking to the bathroom to keeping track of your doctor’s appointments. This robot’s advanced artificial intelligence (AI) learns your preferences, knows your birthday...... Read Full article on HadNews

Swedish scientists have discovered how to use nanorobots to target and kill cancer cells. Made of amino acids, the tiny robots can be injected into the body. They can activate ‘death receptors’ in cells, helping to shrink tumors. All cells have death receptors, so the main obstacle has been finding a way for the robots to identify the harmful cancer cells, rather than attacking healthy cells and cancerous ones alike. The team of scientists, based in the Karolinska Institutet in Sweden, had been working on finding this ‘kill switch’ for years, ever since they first discovered how to create the tiny robots made from amino acids. How do t...... Read Full article on HadNews

“Some scientists refer to the immune system as the seventh sense,” says Dr. Hao Jin, a neuroimmunologist at the National Institute of Allergy and Infectious Diseases (NIAID). It’s a comparison that anyone who’s ever had a common cold can appreciate. Much like our traditional senses help us perceive and interact with our external world, our immune system — a complex network of cells, tissues, and organs — helps us sense and respond to threats in our internal environment. And, as we all know, it’s not always a pleasant experience. When bacteria or viruses invade our body, our immune system springs into action, releasing pro-inflammatory molecu......

If health is a fundamental human right, health-care delivery must be improved globally to achieve universal access. However, the limited number of practitioners creates a barrier for all health-care systems. Approaches to health-care delivery driven by artificial intelligence (AI) are poised to fill this gap. Whether in urban hospitals or in rural and remote homes, AI has the reach that health-care professionals cannot hope to achieve. People seeking health information can obtain it quickly and conveniently. For health care to be effective, patient safety must remain a priority. The news is filled with examples of novel applications of AI....... Read Full article on HadNews

La pérdida de visión es una de las discapacidades más graves que una persona puede enfrentar, afectando todos los aspectos de su vida. Lo sorprendente es que el 80% de las causas de ceguera o disminución severa de la agudeza visual se pueden prevenir o tratar. El oftalmólogo Santiago González Virgili comparte su experiencia en la lucha contra la ceguera evitable. Realiza cirugías de cataratas, la primera causa de ceguera en el mundo, en áreas rurales de Argentina, devolviendo la visión a personas que han quedado ciegas por esta condición tratable. Además, proporciona anteojos a personas con problemas de refracción no corregidos, lo que les pe...... Read Full article on HadNews

Lung cancer is responsible for more deaths than breast, colon and prostate cancer combined. With advancements in lung cancer screening, it is expected that more patients will be diagnosed at earlier stages, enabling them to undergo surgery, the primary treatment modality for early-stage patients. However, a significant proportion of patients will have a recurrence of their cancer after resection (surgery to remove the tumour). Unfortunately, current clinical guidelines cannot help predict which patients are at risk. Better knowledge of who is at risk has significant implications for systemic therapy selection such as chemotherapy for early...... Read Full article on HadNews
