Health volunteers who support pilgrims during Hajj must understand heatstroke because the desert climate can push bodies into danger quickly. The disease happens when the body cannot cool itself, often after long walks or standing in the sun for many hours. Older pilgrims and those with chronic illn
Health insurers are increasingly turning to artificial intelligence to streamline claims, detect fraud, and predict patient needs. But who keeps an eye on how these powerful tools are being applied? A growing number of regulators and watchdog groups are stepping up their scrutiny. The Centers for
Health care in the United States costs almost one‑fifth of the country’s economic output, far more than other rich nations. The reasons lie in how the system is organized, funded and run, rather than in medical technology alone. Across the world there are four main ways to deliver health services.
Health systems often find it hard to use local and published data to make quick decisions, especially in areas like primary care that change fast. The idea of learning healthcare systems (LHS) suggests that learning should happen all the time through real-world use. But putting this into practice wi
Plants have a clever chemical called salicylic acid that acts like an alarm system when attackers arrive. In the common lab plant Arabidopsis, scientists first mapped out how this alarm works: a special route called the isochorismate pathway makes salicylic acid, proteins named NPR bind to it, an
Plants use a tagging system called ubiquitination to control the life span of many proteins. In the case of phenylpropanoid production, which supplies important compounds like lignin and flavonoids, several enzymes are marked for destruction by this system. F‑box proteins act as the taggers. They
Plants do not instantly snap back to their normal state after a tough season. They keep biochemical signs of past hardships that change how they act when new challenges appear. This lasting imprint is called biochemical memory. It shows up as shifts in protective molecules, balance of oxidants and a
Health leaders see AI as a tool that can change how care is done. Many think it will help doctors, nurses and back‑office staff save time and give patients better outcomes. Yet most teams are still testing ideas instead of using AI across the whole organization. The real power of AI comes when peop
Plants and the microbes that help them survive harsh weather can be made stronger by boosting a natural compound called glycine betaine. This molecule helps cells keep the right balance of water and protects them from heat, salt or drought. Traditionally, betaine comes from plants grown in specific
Health authorities in Asia are boosting their defenses after Nipah virus cases surfaced in India. This rare but dangerous virus, which jumps from animals to humans, has infected five people in the southwestern state of Kerala. While Indian officials say the outbreak is contained to two districts, ne
