Losing your brain may seem like the end of the world. For one small marine animal, it’s part of growing up. The tiny sea creature known as the Sea Squirt replaces its brain over and over again throughout its life. This marine animal is a member of the genus Ciona. It looks like a soft blob that’s attached to rocks. Sea squirts are not born as stationary blobs. Ciona intestinalis is a sea squirt that lives in temperate coastal water and is known as the sea vase. It’s a solitary, transparent, filter-feeding seasquirt. As larvae they look like tiny tadpoles, measuring between 1-2 mm in length. They have a simple cerebral organ (also known as a. The larval brain contains 200 neurons involved in sensory processing, according to electron microscopy studies. Studies using electron microscopy show that the larval brain contains ~200 neurons involved in sensory processing.Then, something bizarre happens: upon settling headfirst via adhesive papillae, metamorphosis triggers autophagy–self-digestion of ~80% of the central nervous system, including most of the brain, tail, and notochord tissues within hours.Why would an animal do that?Also Read | The frog that breaks its own bones to grow clawsAs an adult, it becomes a stationary filter feeder, staying fixed in one place and feeding by pulling in water. It uses tiny openings called gills to filter out nutrients and plankton. It can actually pump more than 100 times its body volume of water each day. It is expensive to maintain a brain, as they can consume a lot of energy. Scientists have discovered that genes that are linked to brain development are much less active when the animal settles. The body also produces enzymes to help break down the unused brain tissues. Continue reading below this ad. It retains only a small number of nerve cells, just enough to perform basic reflexes like closing its eyes when something touches it. So is the brain really replaced? The sea squirt develops a simple, free-swimming brain, and then absorbs the entire thing once it settles. It sheds traits that it briefly shared with chordates, from which it diverged around 550,000,000 years ago. This unusual life cycle challenges that brains are preserved in all closely related species. In a sense, the sea squirt is a lesson in efficiency. Intelligence is not always needed, but it depends on the situation. Scientists have found that the brain resorption can be delayed if an animal is prevented from settling down, proving it is not a fixed time frame but rather a response to a situation. In nature, survival doesn’t mean holding on to complexity. It’s about keeping what you need.

When someone has a high fever, it is instinctive to cool down the body as quickly as possible – sometimes with cold water. Experts say that this approach can be counterproductive. Dr Meenal Thakral of Artemis Hospitals says that using lukewarm or room-temperature water is safer and more effective. “Water at room temperature or lukewarm cools the body without stressing it out,” explains Dr Thakral. During a fever the body’s thermostat is already higher. She says that cold water causes the blood vessels to constrict and can cause shivering. This actually increases the heat. She adds that “it allows heat to escape slowly through the skin and helps bring the temperature down in a natural way.” It’s also far more comfortable, especially for children, making the process calmer and more effective.DISCLAIMER: This article is based on information from the public domain and/or the experts we spoke to. Is tap water better for fever? (Photo: Freepik).Can cold water make a fever worse? “When very cold water has been applied, the body attempts to conserve heat,” explains Dr Thakral. This causes shivering, and the body tries to conserve heat. The cooling effect is only temporary. Children and older adults have less stable body temperature control systems, explains Dr Thakral. Children tend to shiver more quickly, which can increase their body temperature. Older adults may have slower reactions and poor circulation. She says that cold sponge baths may make people feel weak, unwell, or even sick. The safest way of giving a sponge bath. Dr Thakral recommends using a soft towel and lukewarm water. “Gently sponge the forehead, neck and armpits. These are areas where heat can escape easily.” She warns against overdoing. “Do not use extremely cold water or soak your entire body. She says that the goal is to keep the room warm, and not cool it down quickly. “Alongside this, ensure proper water intake and follow your doctor’s advice on medications like paracetamol.” Story continues below this adDISCLAIMER : This article was based on public domain information and/or experts we spoke with.

Functional exercisesShoulders are a fundamental body movement, also known by the term multi-joint exercise, that reflects everyday behaviour. Varun Rattan is the co-founder of The Body Science Academy. “When we climb a flight of stairs, we lunge. When we lift a bag of rice from the ground, deadlift. And when we carry our shopping bags and walk to our cars, we do loaded carrying,” he said. They are functional and mimic real-life movements. This makes them easier to do everyday activities. For a healthier older age, the foundation must begin in your 20s and 30s. Dr Raghu Nagarraj, director of the Institute of Orthopaedics, Sports Medicine and Robotic Joint Replacement, Kauvery Hospitals, Bengaluru, said that a structured routine for older people should include strength training, mobility, and controlled cardio exercise. “While strength work preserves muscle mass and supports joints stability, mobility exercises maintain flexibility and reduce stiffness. “Focus on controlled movements and functional patterns, supported by adequate protein intake and recovery,” he conlcuded.Story continues below this adALSO READ | The ultimate fitness blueprint for men in their 20s: Six exercises to build strength, flexibility, and resilienceProteinAccording to fitness trainer Garima Goyal, protein remains a cornerstone of healthy ageing. “Adequate intake of protein supports muscle mass, immunity function and recovery. Easy-to-digest protein sources such as lentils (as tolerated), paneer, fish, yoghurt or yoghurt can help someone in their 80s maintain strength and independence. The combination of protein with complex carbohydrates and vegetables rich in fibre also helps to maintain energy levels and reduces fatigue after meals,” said Goyal.
