National Science Day 2023: Theme, History, Significance, Activities

On February 28, it is observed to honour Dr C.V. Raman and his discovery of the Raman Effect. Let's take a look at the history, significance, theme, and celebration of National Science Day in 2023

Chandrayaan-3 tested successfully, likely to be launched in June: ISRO

Indian Space Research Organisation (ISRO) on Sunday said that the 'Chandrayaan-3' lander has "successfully" underwent the Electro-Magnetic Interference/Electro-Magnetic Compatibility (EMI/EMC) test between January 31 and February 2 at the U R Rao Satellite Centre here. The EMI/EMC test is conducted for satellite missions to ensure the functionality of the satellite subsystems in the space environment and their compatibility with the expected electromagnetic levels, ISRO said. It said, this test is a major milestone in the realisation of the satellites. According to the space agency, Chandrayaan-3 interplanetary mission has three major modules. They are - the Propulsion module, Lander module and Rover, and the mission's complexity calls for establishing radio-frequency (RF) communication links between the modules. "During the Chandrayaan-3 lander EMI/EC test, Launcher compatibility, Antenna Polarization of all RF systems, Standalone auto compatibility tests for orbital and powere

Autopsies show coronavirus lingers in brain, other parts for months: Study

The SARS-CoV-2 virus spreads throughout the body, including the brain, and lingers for almost eight months, shows an analysis of tissue samples from the autopsies of people who died due to COVID-19. The researchers from the US National Institutes of Health (NIH) tested samples from autopsies that were performed from April 2020 to March 2021. They conducted extensive sampling of the nervous system, including the brain, in 11 of the patients. All of the patients died with COVID-19, and none were vaccinated. The blood plasma of 38 patients tested positive for SARS-CoV-2, three tested negative, and plasma was unavailable for the other three. Thirty per cent of the patients were female, and the median age was 62.5 years. Twenty-seven patients (61.4 per cent) had three or more comorbidities. The median interval from symptom onset to death was 18.5 days. The study, published in the journal Nature, showed that SARS-CoV-2 primarily infected and damaged airway and lung tissue. However, the

Nagoya University identifies neurons which maintain body temperature

A group of neurons, called EP3 neurons, in the preoptic area of the brain play a key role in regulating body temperature in mammals, reported a research group at Nagoya University in Japan.

Grasslands can be managed to benefit biodiversity and soil health: Study

Researchers have shown for the first time that less intensively managed British grazed grasslands have on average 50 per cent more plant species and better soil health than intensively managed grassland. The new study could help farmers increase both biodiversity and soil health, including the amount of carbon in the soil of the British countryside.Grazed grassland makes up a large proportion of the British countryside and is vital to farming and rural communities. This land can be perceived as only being about food production, but this study gives more evidence that it could be key to increasing biodiversity and soil health.Researchers at the UK Centre for Ecology & Hydrology (UKCEH) studied 940 plots of grassland, comparing randomly selected plots which sampled the range of grassland management across Great Britain; from intensively- managed land with a few sown grassland species and high levels of soil phosphorus (indicating ploughing/reseeding and fertiliser and slurry ...

Scientists seek to develop hybrid coral reef off of Miami shores

Scientists and students from the University of Miami dove into the dark waters a few miles off the shores of Miami this week as part of an effort to develop hybrid reefs. The team from the Rosenstiel School of Marine, Atmospheric, and Earth Science was on a mission to collect eggs and sperm from spawning staghorn coral, which they hope to use to fertilise other strains of staghorn corals in a lab. It's all part of a USD 7.5 million federal grant from the U.S. Defense Advanced Research Projects Agency to help address security threats to the military and civilian infrastructure along vulnerable coastal regions in Florida and the Caribbean. The Miami-based project seeks to protect coastal bases from damaging hurricane storm surge using hybrid reefs. Our mission is to develop hybrid reefs that combine the wave-protection benefits of artificial structures with the ecological benefits of coral reefs, said Andrew Baker, a professor and director of the Coral Reef Futures Lab at the Rosenst
