New Malaria Vaccine Becomes First To Exceed WHO Efficacy Goal Of 75 Percent
A new malaria vaccine is the first to have achieved the World Health Organization’s efficacy goal of 75 percent, marking a turning point for a potential malaria vaccine to be commercially available. The vaccine reached a 77 percent efficacy in clinical trials in children between 5 years and 17 months, and was well tolerated with no adverse effects reported. If the next clinical trial is successful, a viable malaria vaccine could be on the horizon.
Earth's Axis Has Shifted Due To Climate Change, Study Reveals
Global warming is causing Earth to wobble on its axis. The planet’s spin on its axis depends on the distribution of weight around the globe. Human-driven climate change has increased glacier melting in polar regions for decades. By the 1990s, the redistribution of water on Earth's surface due to glacial melt was enough to cause the polar regions to drift driving a shift in the planet's axis, a new study has shown.
South African "Miracle" Cave Confirmed As One Of The Earliest Sites Of Human Activity
When and where early hominins first started dwelling in caves is a big question. Now, a study has revealed a new contender, showing that Wonderwerk cave in South Africa contains some of the earliest evidence for intentional fires and tools made by early humans. Stone tools found in the cave date to the Lower Palaeolithic period 2.6 million to 1.7 million years ago, when early hominins of the Homo and Australopithecus genus were alive.
Watch Ingenuity Break The Martian Speed Record On Its Third Flight
NASA’s Ingenuity helicopter has performed its third successful flight, going further and faster than ever before. It rose 5 meters in the air and flew 50 meters at a top speed of 2 meters per second, which may not seem that impressive, but it just became the fastest-ever moving vehicle on Mars. In comparison, Perseverance, the most advanced rover yet, moves at a glacial 4.2 centimeters per second.
Tiny New Species Of Pumpkin Toadlet Packs Some Seriously Deadly Poison
The saying goes that good things come in small packages, but so too do tiny, deadly amphibians. A new species of pumpkin toadlet the size of a thumbnail has been discovered in the south Mantiqueira mountain range of São Paulo, Brazil. The magnificently orange death-nugget is both poisonous and fluorescent, glowing a fabulous green under UV light. The toadlet’s unique song was crucial in helping identify it as a separate species.
