Steam balloon variants. During ascent the ambient pressure decreases and consequently the gases expand. If the balloon is filled by steam partially (Variant 1), the expanding steam eventually fills the balloon. If the lower part is filled by hot air (Variant 2), extra air flows out from the bottom during the ascent. If the balloon

The higher the resolution, the more precise the forecasts: climate models. Credit: ETH Zurich More Climate models are a success story, given that much of what they predicted has actually come true. Nevertheless, Reto Knutti points out in a blog post, researchers still need new models. In 1950, meteorologists Jule Charney and Ragnar Fjørtoft joined

Credit: Laurentiu Robu, pexels.com More The ability to securely transmit information over the internet is extremely important, but most of the time, eavesdroppers can still generally determine who the sender and receiver are. In some highly confidential situations, it is important that the sender’s and receiver’s identities remain anonymous. Over the past couple of decades,

Scientists have discovered evidence of a massive distributed reservoir of methane formed by chemical reactions deep inside the ocean floor. Abiotic methane – created in reactions that don’t involve organic matter or living creatures – has long been known to exist buried in the seabed and released via deep-sea vents, but the origins of the

A vibrant pinkish-coloured seaweed that grows in temperate tropical waters could end up being a huge aid in reducing greenhouse gases, if scientists in Australia have their way. Researchers are currently looking into ways to sustainably mass-produce the crimson-hued algae – called Asparagopsis taxiformis – after a study five years ago demonstrated it almost completely

Long term exposure to pollutants from vehicle exhaust is linked to a heightened risk of the common eye condition age-related macular degeneration, or AMD for short, suggests research published online in the Journal of Investigative Medicine. Exposure to the highest levels of air pollutants was associated with an almost doubling in risk among those aged

Poo transplants are helping expand koala microbiomes, allowing the marsupials to eat a wider range of eucalypts and possibly survive habitat loss. A study featuring University of Queensland researchers has analysed and altered microbes in koalas’ guts, finding that a faecal transplant may influence what species of eucalypt koalas can feed on. UQ School of

Using the link layer protocol, higher-layer software can request the creation of entanglement without needing to know which quantum hardware system is in the box. Credit: QuTech/Scixel More Researchers from QuTech have achieved a world’s first in quantum internet technology. A team led by Professor Stephanie Wehner has developed a so-called link layer protocol that
