Till to date 13 number of vaccines have been approved/ authorized. So far the scientific studies suggest the virus, SARS-CoV-2(the cause of COVID19), likely had ancestors that originated in bats, followed by transmission to an intermediate host, and that both viruses may have an extended host range that includes primates and other mammals. Many mammalian species host coronaviruses and these infections are frequently associated with severe clinical diseases, such as respiratory and enteric disease in pigs and cattle. Additionally, Molecular phylogenetics revealed that at least one human coronavirus (HCov-OC43) may have originated in cattle or swine and that this virus was associated with a human pandemic that emerged in the late 19th century.
Recent data suggest that coronaviruses can be transmitted from bats to other wildlife species and humans, and from humans to tigers and pigs. Hence, understanding the host range of SARS-CoV-2 and related coronaviruses is essential for improving our ability to predict and control future pandemics. It is also crucial for protecting populations of wildlife species in native habitats and under human care, particularly nonhuman primates, which may be susceptible to COVID-19.
An excellent study published in the journal “Proceedings of the National Academy of Sciences of the United States of America” in August, 2020 revealed some interesting findings that support the above paragraph.

Building world's 1st pyramid
In a preprint study published this summer, researchers proposed that ancient Egyptians built the world's first pyramid the 4,700-year-old Step Pyramid of Djoser, which sits on Egypt's Saqqara plateau using a \"modern hydraulic system\" powered by a long-gone branch of the Nile River.

Once a common sight across India, vultures were abundant scavengers, often seen circling landfills in search of carcasses.
Understanding Monkeypox: Insights and Implications
Monkeypox, a viral zoonotic disease, has gained significant attention in recent years due to its re-emergence and sporadic outbreaks globally.
AI predicts that most of the world will see temperatures rise to 3°C much faster than previously expected
Three leading climate scientists have combined insights from 10 global climate models and, with the help of artificial intelligence (AI), conclude that regional warming thresholds are likely to be reached faster than previously estimated.
Infrared Radiation: A New Player In Mosquito Host-Seeking

Fish Oil May Benefit to Cure Alzheimer's, disorder: new findings
The benefits of fish and fish oil consumption are well-known in medical science as fish is considered a precious food resource that provides sufficient nutrition to humans.
A new class of antivirals could help prevent future pandemics
The arrival of Paxlovid in December 2021 marked another turning point in the COVID-19 pandemic an effective antiviral that has since successfully treated millions.
Turning carbon emissions into methane fuel
Chemists have developed a novel way to capture and convert carbon dioxide into methane, suggesting that future gas emissions could be converted into an alternative fuel using electricity from renewable sources. Carbon dioxide (CO2) is a greenhouse gas that accounts for a large part of Earth's warming climate, and is produced by power plants, factories and various forms of transportation.
