Twinkle twinkle baby star, 'sneezes' tell us how you are      (via sciencedaily.com)     Original source 

Researchers have found that baby stars discharge plumes of gas, dust, and magnetic flux from their protostellar disk. The protostellar disk that surrounds developing stars are constantly penetrated by magnetic flux, and if too much magnetic flux remained, the resulting object would generate a magnetic field stronger than any observed protostar. These newly discovered discharges of magnetic flux, or 'sneezes' as the researchers describes them, may be a vital step in proper star formation.

Oxidant pollutant ozone removes mating barriers between fly species      (via sciencedaily.com)     Original source 

Researchers show that ozone levels, such as those found in many places on hot summer days today, destroy the sex pheromones of fruit fly species. As a result, some natural mating boundaries maintained by species-specific pheromones no longer exist. The research team has shown in experiments that flies of different species mate when exposed to ozone and produce hybrid offspring. Since most of these offspring are unable to reproduce, the results could provide another explanation for the global decline of insects.

The hidden role of the Milky Way in ancient Egyptian mythology      (via sciencedaily.com)     Original source 

Astrophysicists shed light on the relationship between the Milky Way and the Egyptian sky-goddess Nut. The paper draws on ancient Egyptian texts and simulations to argue that the Milky Way might have shone a spotlight, as it were, on Nut's role as the sky. It proposes that in winter, the Milky Way highlighted Nut's outstretched arms, while in summer, it traced her backbone across the heavens.

Discovering exceptional oxide ion conductivity at lower temperatures      (via sciencedaily.com)     Original source 

Oxide ion conductors used in solid-state fuel cells often fail to reach full potential when operating at temperatures below 500 degrees Celsius, but researchers have recently found a solution to this problem. They demonstrated high conductivity and stability in bismuth-containing Sill n oxyhalides with triple fluorite-like layers.

Subterranean storage of hydrogen      (via sciencedaily.com)     Original source 

Scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing carbon-free hydrogen fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.

Do some mysterious bones belong to gigantic ichthyosaurs?      (via sciencedaily.com)     Original source 

Several similar large, fossilized bone fragments have been discovered in various regions across Western and Central Europe since the 19th century. The animal group to which they belonged is still the subject of much debate to this day. A study could now settle this dispute once and for all: The microstructure of the fossils indicates that they come from the lower jaw of a gigantic ichthyosaur. These animals could reach 25 to 30 meters in length, a similar size to the modern blue whale.

A smarter city skyline for flood safety      (via sciencedaily.com)     Original source 

With climate change and rising urbanization, the likelihood and severity of urban flooding are increasing. But not all city blocks are created equal. Researchers investigated how urban layout and building structures contribute to pedestrian safety during flooding. Based on their simulated results, the team recommends modifying building corners and protective block layouts to reduce pedestrian risk.

New four-terminal tandem organic solar cell achieves 16.94% power conversion efficiency      (via sciencedaily.com)     Original source 

Researchers have fabricated a new four-terminal organic solar cell with a tandem configuration with a 16.94% power conversion efficiency (PCE). The new device is composed by a highly transparent front cell that incorporates a transparent ultrathin silver (Ag) electrode of only 7nm, which ensures its efficient operation.

How the moon turned itself inside out      (via sciencedaily.com)     Original source 

Linking analyses of the moon's gravity field with models of its earliest evolution, scientists tell a story of the moon turning itself inside out after it solidified from a primordial magma ocean. The process left behind a vestige of dense, titanium-rich material beneath its Earth-facing side that makes its presence known by gravity anomalies.

Mediterranean marine worm has developed enormous eyes      (via sciencedaily.com)     Original source 

Scientists are amazed at the discovery of a bristle worm with such sharp-seeing eyes that they can measure up to those of mammals and octopuses. The researchers suspect that these marine worms may have a secretive language, which uses UV light only seen by their own species. The advanced vision of such a primitive creature helps to finally settle an epic debate about the evolution of eyes.

CHEOPS detects a 'rainbow' on an exoplanet      (via sciencedaily.com)     Original source 

The CHEOPS space telescope is providing new information on the mysterious exoplanet WASP-76b. This ultra-hot giant is characterized by an asymmetry between the amount of light observed on its eastern terminator -- the fictitious line that separates its night side from its day side -- and that observed on its western terminator. This peculiarity is thought to be due to a 'glory', a luminous phenomenon similar to a rainbow, which occurs if the light from the star -- the 'sun' around which the exoplanet orbits -- is reflected by clouds made up of a perfectly uniform substance. If this hypothesis is confirmed, this would be the first detection of this phenomenon outside our solar system.

Stellar collisions produce strange, zombie-like survivors      (via sciencedaily.com)     Original source 

Densely packed, fast-moving stars at the Milky Way's center can collide with each other. New research uses simulations to explore the outcomes of these collisions. Some collisions are more like 'violent high fives' while others are full-on mergers.
