Floating device turns raindrops into electricity

-
Raindrops are more than a source of fresh water. They also carry mechanical energy that reaches the ground for free, and scientists have been exploring how to turn that energy into electricity for years. Traditional droplet electricity generators, however, often struggle with low efficiency, heavy components, and limited potential for scaling up. A research team from Nanjing University of Aeronautics and Astronautics has now developed a new solution: a floating droplet electricity generator that uses natural water as part of its structure. The result is a lighter, more affordable, and more sustainable way to collect clean energy. The work is described in National Science Review. Most droplet electricity generators use a solid platform and a metal bottom electrode. When a raindrop hits the dielectric film on top, the impact produces an electrical signal. Although this approach can generate hundreds of volts, it relies on rigid, costly materials that limit widespread1 deployment. The new...

CO2 is not only pollutant that caters our attention. it's methane as well

-
A new United Nations assessment on global methane emissions has warned that India, already the world’s third-largest methane emitter, does not have a dedicated policy framework to reduce emissions from its biggest source: agriculture and livestock. The Global Methane Status Report highlights that India’s agricultural activities alone contribute 12% of global agricultural methane emissions, among the highest shares worldwide, largely driven by its vast livestock population and extensive rice cultivation. This is the first official status report since the Global Methane Pledge was introduced by the UN Environment Programme at COP30 According to the report, India emitted around 31 million tonnes of methane in 2020, accounting for 9% of global methane emissions. Methane, a potent heat-trapping gas, is released mainly through enteric fermentation in cattle, manure handling, and paddy cultivation under waterlogged conditions. While the assessment acknowledges that millions of Indian farmers ...

Progress is individual's ability to complicate simplicity.

-
Result matters and in the race of achieving the best, life's actual meaning fades. To achieve is new normal that blurs the real goal and emphasize more on complexity, troubles and offcourse stress. Bhagwat Geeta states believe in timelines and efforts, consequences fabricates accordingly.  “यत्र योगेश्वरः कृष्णो यत्र पार्थो धनुर्धरः। तत्र श्रीर्विजयो भूतिर्ध्रुवा नीतिर्मतिर्मम॥” – Bhagavad Gita 18.78 The biggest change that I have cliffed in my personality is not to be to stressed. Not to make the things so complicated. Not to be webbed too much into life's anecdotes. Not to be entangled highly into people's opinions. Let's keep the things simple and prettier. Three Sigma Rules that enable me in weaving the innocence with aroma of positivity. It helped me in growing and evolving. Below are the explanations that help in making the things better. Such as  1. Simplify to Amplify - सर्वं ज्ञानं परमात्मन्येव निहितं। Every problem has always a very simpler solution. Working ...

Scholar Women insight

-
Image
Women of the Vedic period (circa 1500-1200 BCE), were epitomes of intellectual and spiritual attainments. The Vedas have volumes to say about these women, who both complemented and supplemented their male partners. When it comes to talking about significant female figures of the Vedic period, four names - Ghosha, Lopamudra, Sulabha Maitreyi, and Gargi - come to mind. Ghosha Vedic wisdom is encapsulated in myriad  hymns  and 27 women-seers emerge from them. But most of them are mere abstractions except for a few, such as Ghosha, who has a definite human form. Granddaughter of Dirghatamas and daughter of Kakshivat, both composers of hymns in praise of Ashwins, Ghosha has two entire hymns of the tenth book, each containing 14 verses, assigned to her name. The first eulogizes the Ashwins, the heavenly twins who are also physicians; the second is a personal wish expressing her intimate feelings and desires for  married life .  Ghosha suffered from an incu...

The Matilda Effect: Biasness towards women, how world made women invisible in scientific inventions

-
Women have made contributions to science throughout history, despite facing a variety of challenges due to their gender. One such challenge, which affects the acknowledgment of women’s scientific achievements, is called the Matilda Effect. In order to fully appreciate the accomplishments of women in science and the barriers they have faced, it’s important to understand what the Matilda Effect is and how it has affected women in science. What is the Matilda Effect? The Matilda Effect is a phenomenon where the work of women scientists is downplayed, ignored, overlooked, or attributed to men. The Matilda Effect makes it more difficult to see the contributions women have made to science throughout history, and contributes to the belief that women are not as naturally predisposed to science as men. The Matilda Effect isn’t just about stealing credit. It can manifest in several ways: Downplaying Achievements:  A woman’s work might be considered less significant or ground breaking...

Indian Scientist fails to receive Nobel Prize since ages.. Could be reasons?

-
Image
The major problem remains that the current nature of academia is resistant to change and blocks visionaries. Until this system is dismantled and replaced with transparent hiring, merit-based funding, and visionary leadership, India will remain a land of potential, not of discovery. India hasn’t produced a Nobel laureate in science in almost a century now. The reason often cited for this predicament is that India doesn’t spend enough on research. Indeed, public investment in R&D must rise to at least 3 per cent of the GDP, as current levels remain modest. But is money really the only, or even the main, problem? Leadership that prioritises control over creativity has turned many temples of science into bureaucratic fortresses. So, is the government responsible for this stagnation, or is academia to blame as well? The answer, unfortunately, points to a crisis of leadership and vision within the system. Even a tenfold increase in funding will not bring transformation unless institution...

Can homegrown app replace whatsapp?

-
Irony is that people love to shout out when there was no Indian platform, people want Indian app to chat and when now we have ARATTAI, millions of Indians don't know about it and many know yet they are not using it. Posting status is symbolised here patriotism and when in reality patriotism is examined million of India prefers to lecture or search for excuses.  This is bitter yet true, Indians suspects indigenous made while prefers to intake lead(Pb) in nestle's Maggie and questions Patanjali atta noodles. Nationalism is curse in our beloved nation. Learnings from South Korea and Japan should be inculcated in our country and penalties to respect National property should be learned by UAE. Civic sense course needs to be exported from some another world to our culturally rich nation.  The anger and frustrations that is overflowing through this article. Acceptable that ARATTAI app's (Indian app) downloads are tremendously high but how people are using this platform is negligib...
