The Covid-19 vaccine
Last year the biggest science story of the year was that scientists developed two mRNA Covid vaccines in record time. The Covid-19 vaccine has now become available for children as young as five. The fastest vaccine development-to deployment period before this was the Mumps vaccine in the 1960s and that took four years.
Only 8 percent of individuals in low-income countries have received at least one dose of the vaccine, and a WHO Africa report from this fall said that on that continent, less than 10 percent of countries would hit the goal of vaccinating at least 40 percent of their citizens by the end of the year. Globally, less than 60 percent of the population has been vaccinated. The holes in vaccination coverage will allow the virus to continue to kill a large number of individuals, and allow an environment where possibly other dangerous variants can emerge.
WHO recommends groundbreaking malaria vaccine for children
In October, the World Health Organization approved the first vaccine against malaria. The approval was not only a first for that disease, but also for any parasitic disease. The recommendation was based on results from an ongoing pilot programme in Ghana, Kenya and Malawi that has reached more than 800 000 children since 2019. WHO recommends that in the context of comprehensive malaria control the RTS,S/AS01 malaria vaccine be used for the prevention of P. falciparum malaria in children living in regions with moderate to high transmission as defined by WHO. RTS,S/AS01 malaria vaccine should be provided in a schedule of 4 doses in children from 5 months of age for the reduction of malaria disease and burden.

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.
Climate change arms the world, ovarian cancer pulls the trigger.It's time we disarm them both
Climate change, driven by human activities, leads to environmental changes such as rising temperatures, altered weather patterns, and increased pollution.
Climate Change Added 18 mph to Hurricane Wind Speeds over Past 5 Years
High ocean temperatures caused by global warming boosted maximum intensities for most storms between 2019 and 2023, as well as for every 2024 hurricane.
How Indian Vulture Decline Led to 500,000 Deaths in 5 Years
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
The sound of mosquitoes is all around us when the sun sets and the air gets warm and sweltering.
Fish Oil May Benefit to Cure Alzheimer's, disorder: new findings

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.
