Climate change will bring more turbulence to flights in the Northern Hemisphere, study finds      (via sciencedaily.com)     Original source 

A type of invisible, unpredictable air turbulence is expected to occur more frequently in the Northern Hemisphere as the climate warms. Known as clear air turbulence, the phenomenon also increased in the Northern Hemisphere between 1980 and 2021.

A recipe for zero-emissions fuel: Soda cans, seawater, and caffeine      (via sciencedaily.com)     Original source 

Engineers discovered that when the aluminum in soda cans is purified and mixed with seawater, the solution produces hydrogen -- which can power an engine or fuel cell without generating carbon emissions. The reaction can be sped up by adding caffeine.

Eyes for Love: Searching for light and a mate in the deep, dark sea, male dragonfishes grow larger eyes than the females they seek      (via sciencedaily.com)     Original source 

The eyes of the male dragonfish grow larger for mate seeking, a sexual dimorphism that makes the dragonfish an anomaly in vertebrate evolution, researchers report.

Weather experts discover new effect of storm -- in a teacup      (via sciencedaily.com)     Original source 

A new study reveals that Storm Ciaran cut an invisible path of mayhem across southern Britain last autumn, destroying any possibility that 20 million people could have a proper cup of tea at breakfast. The storm's record-breaking low pressure meant the boiling point of water was below the crucial 100 degrees Celsius required for a decent cuppa.

Scientists create computer program that 'paints' the structure of molecules in the style of Piet Mondrian      (via sciencedaily.com)     Original source 

Scientists have created a computer program that 'paints' the structure of molecules in the style of famous Dutch artist, Piet Mondrian. Researchers are opening eyes and minds to the beauty of molecular structure, as well as posing new questions about the form and function of the molecules themselves.

Lion with nine lives breaks record with longest swim in predator-infested waters      (via sciencedaily.com)     Original source 

A record-breaking swim by two lion brothers across a predator-infested African river has been documented in a new study. The researchers say the 1km swim is another example of iconic wildlife species having to make tough decisions to find homes and mates in a human-dominated world.

Whale remains tracked to highlight sustainable disposal benefits      (via sciencedaily.com)     Original source 

A new study highlights the sustainable, cultural and ecosystem benefits of offshore removal or decomposition of whale remains. The study tracked the remains of a humpback whale that was intercepted before washing up on the shoreline, then repositioned 30km offshore and fitted with a satellite tag that tracked its position as it drifted with the wind and currents for 6 days before falling to the seabed.

Groundbreaking study reveals oceanic seabirds chase tropical cyclones      (via sciencedaily.com)     Original source 

A new study reveals that the rare Desertas Petrels (Pterodroma deserta), a wide-ranging seabird in the North Atlantic, exhibit unique foraging behaviors during hurricane season. Contrary to other pelagic seabirds, these petrels do not avoid intense tropical cyclones but instead exploit the dynamic conditions for their benefit, providing new insights into the impact of cyclones on open ocean marine life.

Organic material from Mars reveals the likely origin of life's building blocks      (via sciencedaily.com)     Original source 

Two samples from Mars together deliver clear evidence of the origin of Martian organic material. The study presents solid evidence for a prediction made over a decade ago that could be key to understanding how organic molecules, the foundation of life, were first formed here on Earth.

Investigating newly discovered hydrothermal vents at depths of 3,000 meters off Svalbard      (via sciencedaily.com)     Original source 

Hydrothermal vents can be found around the world at the junctions of drifting tectonic plates. But there are many hydrothermal fields still to be discovered. During a 2022 expedition of the MARIA S. MERIAN, the first field of hydrothermal vents on the 500-kilometer-long Knipovich Ridge off the coast of Svalbard was discovered.

Shocked quartz reveals evidence of historical cosmic airburst      (via sciencedaily.com)     Original source 

Researchers continue to expand the case for the Younger Dryas Impact hypothesis. The idea proposes that a fragmented comet smashed into the Earth's atmosphere 12,800 years ago, causing a widespread climatic shift that, among other things, led to the abrupt reversal of the Earth's warming trend and into an anomalous near-glacial period called the Younger Dryas.

Small, adsorbent 'fins' collect humidity rather than swim through water      (via sciencedaily.com)     Original source 

Clean, safe water is a limited resource and access to it depends on local bodies of water. But even dry regions have some water vapor in the air. To harvest small amounts of humidity, researchers developed a compact device with absorbent-coated fins that first trap moisture and then generate potable water when heated. They say the prototype could help meet growing demands for water, especially in arid locations.
