The bushfires raging across Australia this summer have sharpened the focus on how climate change affects human health. This season bushfires have already claimed more than 30 human lives, and many people have grappled with smoke inhalation and mental health concerns. The changing nature of bushfires around the world is one of the tragic consequences

A species of jellyfish hunts its prey by hurling venom grenades to create “stinging water”, researchers said Thursday, solving a long-standing mystery as to how they gather food without tentacles. The upside down jellyfish (Cassiopea xamachana), found in shallow waters around Florida, the Caribbean and Micronesia, is a frequent nuisance to snorkelers and surfers who appear

Scientists in Antarctica have recorded a new record temperature of 20.75 degrees Celsius (69.35 Fahrenheit), breaking the barrier of 20 degrees for the first time on the continent, a researcher said Thursday. “We’d never seen a temperature this high in Antarctica,” Brazilian scientist Carlos Schaefer told AFP. He cautioned that the reading, taken at a

While period cramps are never fun, they can actually be debilitating for those with endometriosis – a disease where rogue uterine tissue turns up in places that it doesn’t belong. Like in other areas of the pelvis… or even in the lungs or the brain. Hosted by: Olivia Gordon SciShow has a spinoff podcast! It’s

Sifting through a soup of genes sampled from many environments, including human saliva, animal poop, lakes, hospitals, soils and more, researchers have found hundreds of giant viruses – some with abilities only seen before in cellular life. The international team, led by scientists from University of California, Berkeley, has discovered entire new groups of giant

Scientists have managed to get two quantum memories entangled over 50 kilometres (31 miles) of fibre optic cables, almost 40 times the previous record. This achievement makes the idea of a super-fast, super-secure quantum internet a much more plausible one. Quantum communication relies on quantum entanglement, or what Einstein called ‘spooky action at a distance’: where

Picture the space around Earth filled with tens of thousands of communications satellites. That scenario is slowly coming into being, and it has astronomers concerned. Now a group of astronomers have written a paper outlining their detailed concerns, and how all of these satellites could have a severe, negative impact on ground-based astronomy. SpaceX and other

The gene pool of modern West Africans contains the ‘ghost’ of a mysterious hominin, unlike any we’ve detected so far. Similar to how humans and Neanderthals once mated, new research suggests this ancient long-lost species may have once mingled with our ancestors on the African continent. Using whole-genome data from present-day West Africans, scientists have

Ebola. SARS. Rabies. MERS. Most probably even the flourishing new coronavirus, COVID-19. There’s one animal that innocently and unwittingly gifts all these virulent scourges to humanity. Bats. Why is that? According to new research, it’s because bats may be the ultimate incubator, courtesy of a fiercely effective and robust immune system that seems to, in

A large asteroid whooshed past Earth last week, and mooned all of humanity in the process. As it approached Earth space, asteroid 2020 BX12 was under close observation. Clocking in at 200 to 450 metres across (656 to 1,476 feet), and moving at around 90,000 kilometres per hour (56,000 miles per hour), the space rock
