Life-supporting Moons can only form around small planets: Study
Because of the large size of the Moon compared to the planet, it controls the length of Earth's day and governs ocean tides. The moon also stabilises Earth's axis of rotation, which in turn stabilises its mild climate, which is favorable for life. According to the scientists, the Moon was born from a cataclysmic collision of a nascent Earth with a Mars-size world known as Theia.

NASA's Mars orbiter finds water flowed on Red Planet longer than thought
Two scientists studying data from NASA's Mars Reconnaissance Orbiter found signs of liquid water on the Red Planet as recently as 2 billion to 2.5 billion years ago, meaning water flowed there about a billion years longer than previous estimates. The findings, published in the journal AGU Advances, centre on the chloride salt deposits left behind as icy meltwater flowing across the landscape evaporated.
NASA scientists study Tonga eruption to understand landforms on Mars, Venus
The unusual explosion -- which has been calculated at more than 500 times the force of the atom bomb dropped on Hiroshima, Japan, in 1945 -- is offering researchers a rare chance to study how water and lava interact. Studying the Hunga Tonga-Hunga Ha'apai volcano and its evolution in recent weeks is "important for planetary science", Petr Broz, a planetary volcanologist at the Institute of Geophysics of the Czech Academy of Sciences in Prague, was quoted as saying.
NASA citizen scientist spots Jupiter-like planet
The exoplanet, called TOI-2180 b, was discovered in data from NASA's Transiting Exoplanet Survey Satellite (TESS). TOI-2180 b is almost three times more massive than Jupiter but has the same diameter, meaning it is more dense than Jupiter. This made scientists wonder whether it formed in a different way than Jupiter. Further, through computer models the team determined that the new planet may have as much as 105 Earth masses worth of elements heavier than hydrogen and helium.
Glenmark gets US FDA approval for nasal spray
According to Glenmark, the drug is for rhinitis in adults and paediatric patients 12 years of age and older in the US. "The FDA's approval of Ryaltris represents a major milestone for Glenmark and clearly supports our efforts to bring innovative treatment options in our key therapeutic areas." said Chief Commercial Officer Robert Crockart.
AstraZeneca 3rd dose increases antibody response against Omicron
The trial showed the third dose booster also increases the immune response to Beta, Delta, Alpha, and Gamma SARS-CoV-2 variants. The results of both were observed among individuals previously vaccinated with either AstraZeneca, Vaxzevria in the UK, or an mRNA vaccine.
Millets can boost growth by 26-39%, reveals study
Researchers examining the nutritional benefits of millets have found that these 'smart foods' can significantly contribute to overcoming malnutrition. The study was published in the journal 'Nutrients' and is a review and meta-analysis of eight prior published studies. It was undertaken by seven organisations in four countries and was led by Dr S. Anitha, Senior Scientist-Nutrition at the International Crops Research Institute of the Semi-Arid Tropics (ICRISAT).
No need for 4th Covid jab yet: UK experts
UK Health Security Agency data show three months after boosting, protection against hospitalisation remains at about 90 per cent for people aged 65 and over, the BBC reported. Protection against mild symptomatic infection is more short-lived, the data revealed.
That drops to around 30 per cent by about three months, it added.
Covid-recovered at 3-5 times more Omicron reinfection risk: WHO
According to Hans Henri P Kluge, the WHO's Regional Director for Europe, Omicron variant can evade previous immunity in people. "So it can still infect those who have had Covid-19 in the past, those who are unvaccinated, and those who were vaccinated many months ago," Kluge said in a recent note. "There are three things that we need to do urgently: protect ourselves through vaccination, prevent further infections, and prepare health systems for a surge in cases".
