All the electronic devices that we use today have components made of semiconductors, mostly silicon. In recent years, gallium nitride, another semiconductor, is making its way into electronics. It is better suited for high power and high-frequency applications. Researchers from IISc have developed India’s first-ever e-mode gallium nitride power transistor, whose performance is comparable to some of the best reports till date.

இந்தியா சுமார் 270 வகை பாம்பினங்களுக்கு இருப்பிடமாக திகழ்கிறது. இதில் சுமார் 60 இனங்கள் நச்சுத்தன்மை வாய்ந்தவையாகும். பல்லுயிர் வெப்ப மையமாக (biodiversity hotspot) விளங்கும் இந்தியாவின் மேற்குத்தொடர்ச்சி மலைக்காடுகளில், புதுப்புது தாவர மற்றும் விலங்கினங்கள் கண்டறியப்படுவது அடிக்கடி நிகழும் ஒன்றாகும்.
Very soon, the shortage of water and population explosion in the world may cost you your plate of biryani, and for many, their livelihood. Researchers from ICAR-Indian Institute of Rice Research, Hyderabad and Telangana State Agricultural University, Hyderabad, have identified essential genes that help in the adaptation of aerobic rice to water-scarce conditions.
Researchers at the Indian Institute of Technology, Kanpur, have developed a biomolecule-based fertiliser that can help address the drawbacks of chemical fertilisers.
Two Russian institutes—A.N.Severtsov Institute of Ecology and Evolution and Moscow State Agricultural University, and the Centre for Cellular and Molecular Biology, India, have compared the chemical contents of the faecal matter of the Amur and Bengal tigers to examine the stress levels of these tigers in India and Russia.
एशिया, युरोप, दक्षिण अमेरिका और ऑस्ट्रेलिया सहित भारतीय प्रौद्योगिकी संस्थान दिल्ली के शोधकर्ताओं की एक बहु-राष्ट्रीय टीम ने 39 देशों के लगभग 17 हज़ार लोगों का सर्वेक्षण किया, यह जानने के लिए कि समाजों के बीच पारस्परिक सम्बंध भिन्न क्यों हैं?
Do you remember poking a plant that quickly closed its leaves, seemed to droop and shy away? An introvert among plants and a favourite among all of us, the touch-me-not or chuimui in Hindi, is aptly named Mimosa pudica by scientists, where pudica is Latin for shy or chaste.
গোলকীয় উষ্ণতা বৃদ্ধিৰ কথা ক’লে আমাৰ মনলৈ হিমবাহৰ গলন, সাগৰ পৃষ্ঠৰ উচ্চতা বৃদ্ধি আৰু জৈৱ বৈচিত্ৰৰ প্ৰতি ইয়াৰ
On April 26 2019, scientists at the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo Interferometer detected gravitational waves from a possible black hole-neutron star collision thought to have taken place 1.2 billion light years away.
