A homegrown device is in the works that could determine you brain's health in quite literally the blink of an eye by transforming how doctors diagnose and monitor neurological disorders
In modest labs tucked away in the Indian Institute of Science , Bengaluru, scientists have engineered a spectacle-mountable device that does more than sharpen your vision — it peers into your brain's health. This is not science fiction. It's a working apparatus and could change how doctors diagnose and monitor neurological disorders .

Scientists call for digital transition of Bengaluru's VITM on diamond jubilee
Visvesvaraya Industrial and Technological Museum (VITM), a landmark scientific institution located in Bengaluru, celebrated its diamond jubilee on Sunday. The museum was inaugurated on July 27, 1965. During the event, people from the scientific community called for a digital transition of the museum. 'We live in a digital world, and we need to keep changing with the times. We want VITM to become more and more advanced digitally as the digital world does not have the constraints that are present in the physical world. With a technology like Virtual Reality (VR) glasses, students can experience unknown worlds, walk on Mars, or take a deep dive into the nano world. The possibilities are infinite in the digital world, and it should be expanded to make students realise how wondrous science is,' said Govindan Rangarajan, Director of Indian Institute of Science, while speaking at the event. He also said that physical experience at a museum is equally important. 'Such a museum is critical these days as all youngsters are immersed in their phones and do not have tactile stimulation. When they come here and actually see the exhibits, feel them, and work on them with their own hands, it is a different experience for this generation. They will get inspired to choose a career in science and mathematics while interacting with these artefacts. We should transition to the digital world while also keeping the physical world (intact).' The renovated 'Fun Science Gallery' was also inaugurated as part of the celebrations on Sunday. The gallery includes practical applications related to basic physics and science, the level of which is taught in high school and college. It also has puzzles and illusions for students to solve and experience. B. Venkataraman, chairman of VITM's Executive Committee also stressed on digital transition. 'This museum has been a beacon of scientific knowledge, innovation, and inspiration since its inception. Over the years, it has fostered love for science and technology among millions, becoming a dynamic space where learning meets creativity and imagination. The way forward is digital, and in this era of transition, we need to delve deeply (into the digital world) and make sure that the mission continues,' he said.

These simple moves done every day help fire up neurons in the brain, boost and maintain coordination, and help keep dementia at bay.(Freepik) Also Read | Neurologist shares 4 unmissable things parents should know to support healthy brain development in kids Several large studies have found that the risk of dementia and Alzheimer's disease increases in people aged 50 years or older. However, training your brain may help slow memory loss and other mental problems. In a post shared on July 25, Anna Seo, licensed acupuncturist and integrative health specialist, shared dementia preventing hacks - 3 hand exercises - that you should practise every day.

These simple moves done every day help fire up neurons in the brain, boost and maintain coordination, and help keep dementia at bay.' She stressed that taking our brains to the gym after staring at emails and Excel sheets all day is crucially important. 'Your future self will thank you,' she added. Let's find out the exercises she suggested: 1. Alternate clapping To do this exercise, begin by clapping your hands normally for two counts. Then, switch the position by clapping for one count with your palms overturned. Now, do these movements alternatively while changing the position of your palms when they are overturned. 2. Alternating thumb and pinky finger Make fists with both your hands. Now, stick out the thumb of your right hand and the pinky finger of your left hand. Then, change the fingers, with the thumb of your left hand and the pinky finger of your right hand sticking out. Do these movements one after the other. 3. Asymmetrical finger taps For this movement, you have to touch the first digit of your fingers to the thumb, but the movements of both hands will be different. For the right hand, you will begin by touching your finger with the thumb, while simultaneously touching the pinky finger on your left hand. Then, continue moving forward with this asymmetric movement. Note to readers: This article is for informational purposes only and not a substitute for professional medical advice.

Solar Eclipse 2025: When and where to watch the final eclipse of the year and why it is important
As the year moves forward, curiosity is building around the last solar eclipse of 2025. Like always, these celestial events attract attention from both scientists and skywatchers– and this one's no exception. From researchers to those who follow age-old beliefs, many are eager to know what to expect from the second and final solar eclipse of the year. Here's everything we know about it so far. Date and timing of the final solar eclipse The final solar eclipse of 2025 is set to take place on September 21. It will start late at night around 11:00 PM (IST) and continue into the early hours of September 22, ending at 3:24 AM (IST). This will be a partial solar eclipse, which means the Moon will cover only a part of the Sun– so the eclipse won't be total, but still a noteworthy event for skywatchers. Visibility of the eclipse Since this eclipse will occur during nighttime in some regions, it won't be visible everywhere– only areas experiencing daylight at that time will be able to see it. Because of this, the Sutak period won't be observed in places where the eclipse isn't visible. According to traditional beliefs, Sutak– a time when people avoid certain religious and household activities– is only followed if the eclipse can actually be seen from that location. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Stylish New Mobility Scooters Available for Seniors (Prices May Surprise You) Mobility Scooter | Search Ads Search Now Undo Where will the eclipse be seen? According to NASA, the partial solar eclipse on September 21, 2025, will be visible from parts of eastern Australia, New Zealand, Antarctica, and regions over the South Pacific Ocean. There may also be limited visibility along the edge of the South Atlantic Ocean. The eclipse will not be visible from India, Europe, Africa, or the Americas. This visibility pattern has also been confirmed by platforms like TimeandDate and EarthSky, which report similar regions based on global eclipse tracking data. In areas where the eclipse is visible, the extent to which the Moon covers the Sun will vary depending on local timing and weather conditions. Second lunar eclipse also in September In addition to the solar eclipse, another major astronomical event is expected earlier in the same month. The second lunar eclipse of 2025 is set to occur on 7 September. What is a solar eclipse? A solar eclipse occurs when the Moon moves between the Earth and the Sun, casting a shadow that blocks the Sun's light– either fully or partially. In the case of a partial solar eclipse, only a portion of the Sun is obscured by the Moon. This type of eclipse is visible only from certain parts of the world, depending on the viewer's location and the timing of the event.
