 In a groundbreaking scientific breakthrough, a brain implant gives a blind woman artificial vision. For the first time in 16 years, a blind lady was able to sense two-dimensional objects and letters thanks to a 'visual prosthesis' implanted directly into her brain. The researchers behind this incredible advancement in optical prosthesis recently published the results of their trials, revealing insights that potentially transform how we assist folks who have lost their vision see again. Berna Gomez was diagnosed with toxic optic neuropathy at the age of 42, a dangerous medical illness that quickly damaged the optic nerves that connect her eyes to her brain. The features of Gomez' two children and husband had dissolved into darkness in just a few days, and her career as a science teacher had come to an abrupt end. Then, in 2018, at the age of 57, Gomez took a risky step. She agreed to be the first person in the world to have a small electrode with a hundred microneedles impl...

A Singaporean team has developed a device that uses electric signals to 'talk' to plants.  For generations, scientists have been fascinated by the Venus flytrap's (Dionaea muscipula) unusual shape and characteristics. "One of the most magnificent [plants] in the world," wrote Charles Darwin. He was enthralled by the plant's ability to adapt to nutrient-poor, harsh environments and live and evolve. Many decades later, Jagadish Chandra Bose, a plant physiologist among other things, noticed that the plant's leaves were sensitive to touch and created electrical impulses, which were similar to the signals produced by our bodies. Researchers at Singapore's Nanyang Technological University (NTU) have now discovered a method to manipulate these electrical impulses. They've created an electronic system that can send electrical impulses to plants and receive signals in return, all of which is controlled by a smartphone app. Farmers might use their technology...

Over the last ten years, Indians  have   become shorter According to a new study, the average height of Indian men and women has decreased over the last ten years, with women from Scheduled Tribes (ST) suffering the greatest reduction. Researchers from Jawaharlal Nehru University (JNU) examined data from the health ministry's National Family Health Surveys (NFHS) to see how average height varies by gender, wealth, and social class. To investigate the trends, the researchers examined data from the NFHS-II (1998–99), NFHS–III (2005–06), and NFHS–IV (2015–16).  The study, which was published in the journal PLoS One, examined male and female age groups of 15–25 and 26–50 years. While the average height of women across age groups improved substantially between NFHS-II and III, it decreased dramatically between NFHS-III and IV in the 15-25 year age group. The average height of men aged 15–25 years and 26–50 years fell significantly — 1.10 cm and 0.86 cm, respectively — in both ...

Why is there a computer chip scarcity throughout the world?  The semiconductor chip scarcity, which has hampered numerous industries, particularly the auto industry, is unlikely to be resolved very soon. The spread of the delta form, along with poor vaccination rates in several ASEAN nations and China's zero-tolerance Covid approach, has caused governments to impose restrictions and order industrial or port closures, according to a recent research by Nomura. Apart from that, in August, a lack of raw materials and container availability increased lead times the period between ordering a chip and receiving it. This is especially true in nations like Vietnam, South Korea, and China, which are part of industrial supply networks. This comes at a time when most chip supplies throughout the world are already running low. According to Nomura, input shortages and low stocks would likely result in production cutbacks and delayed shipments in the September 2021 quarter. "In reality, the ...

 Surgeons in the United States have successfully tested a pig kidney transplant in a human patient. For the first time, a pig kidney has been transplanted into a person without the recipient's immune system rejecting it right away, a potentially significant breakthrough that might ultimately help ease a critical scarcity of human organs for transplant. The operation was carried out at NYU Langone Health in New York City, and it entailed the use of a pig whose genes had been changed such that its tissues no longer contained a chemical that causes nearly instant rejection. According to Reuters, the receiver was a brain-dead woman with indications of renal disease whose family agreed to the experiment before she was scheduled to be taken off life support. The replacement kidney was connected to her blood arteries and kept outside her body for three days, allowing researchers access to it. The function of the transplanted kidney "appeared quite typical," according to the stud...

Earth receives the first radio signals from the galaxy's centre, which point to hidden planets and  Aliens   Astronomers have found strange signals emanating from the Milky Way's centre. The radio waves fit no known pattern of fluctuating radio source and could indicate the existence of a new class of star object. The ASKAP radio telescope in Western Australia's desert, around 500 miles (800 kilometres) north of Perth, found the set of signals known as ASKAP J173608.2-321635. Experts say the signal flickers on and off at unpredictable intervals for weeks at a time before abruptly switching off' and turning dark, something that does not correspond to any known space objects. According to them, ASKAP J173608.2-321635 has been picked up 17 times in less than two years. 'Throughout 2020 and 2021, we have been searching the sky with ASKAP to locate odd new objects using a study called Variables and Slow Transients (VAST),' Dailymail reported. As quoted by Professor T...
