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.

Immune system in the spotlight      (via sciencedaily.com)     Original source 

Our immune system is always on alert, detecting and eliminating pathogens and cancer cells. Cellular control mechanisms cause diseased cells to present antigens on their surface like signs for the immune system. For analysis of the necessary complex antigen processing and transport processes in real time, researchers have developed a 'cage' that is opened with light to release trapped antigens at a specific place and time.

Food aroma study may help explain why meals taste bad in space      (via sciencedaily.com)     Original source 

A new study on common food aromas may help explain why astronauts report that meals taste bland in space and struggle to eat their normal nutritional intake. This research has broader implications for improving the diets of isolated people, including nursing home residents, by personalizing aromas to enhance the flavor of their food.

Ancient microbes offer clues to how complex life evolved      (via sciencedaily.com)     Original source 

Researchers have discovered that a single-celled organism, a close relative of animals, harbors the remnants of ancient giant viruses woven into its own genetic code. This finding sheds light on how complex organisms may have acquired some of their genes and highlights the dynamic interplay between viruses and their hosts.

New analysis of Cassini data yields insights into Titan's seas      (via sciencedaily.com)     Original source 

A new study of radar experiment data from the Cassini-Huygens mission to Saturn has yielded fresh insights related to the makeup and activity of the liquid hydrocarbon seas near the north pole of Titan, the largest of Saturn's 146 known moons.

Bizarre 'garden sprinkler-like' jet is spotted shooting out of neutron star      (via sciencedaily.com)     Original source 

A strange 'garden sprinkler-like' jet coming from a neutron star has been pictured for the first time. The S-shaped structure is created as the jet changes direction due to the wobbling of the disc of hot gas around the star -- a process called precession, which has been observed with black holes but, until now, never with neutron stars.

Unlocking the mystery of preexisting drug resistance: New study sheds light on cancer evolution      (via sciencedaily.com)     Original source 

The evolution of resistance to diseases, from infectious illnesses to cancers, poses a formidable challenge. Despite the expectation that resistance-conferring mutations would dwindle in the absence of treatment due to a reduced growth rate, preexisting resistance is pervasive across diseases that evolve -- like cancer and pathogens -- defying conventional wisdom.

NASA's Webb investigates eternal sunrises, sunsets on distant world      (via sciencedaily.com)     Original source 

Researchers using NASA's James Webb Space Telescope have finally confirmed what models have previously predicted: An exoplanet has differences between its eternal morning and eternal evening atmosphere. WASP-39 b, a giant planet with a diameter 1.3 times greater than Jupiter, but similar mass to Saturn that orbits a star about 700 light-years away from Earth, is tidally locked to its parent star. This means it has a constant dayside and a constant nightside -- one side of the planet is always exposed to its star, while the other is always shrouded in darkness.

A new neural network makes decisions like a human would      (via sciencedaily.com)     Original source 

Researchers are training neural networks to make decisions more like humans would. This science of human decision-making is only just being applied to machine learning, but developing a neural network even closer to the actual human brain may make it more reliable, according to the researchers.

Scorching storms on distant worlds revealed      (via sciencedaily.com)     Original source 

An international study reveals the extreme atmospheric conditions on the celestial objects, which are swathed in swirling clouds of hot sand amid temperatures of 950C. Using NASA's powerful James Webb Space Telescope (JWST), researchers set out to capture the weather on a pair of brown dwarfs -- cosmic bodies that are bigger than planets but smaller than stars.

Building a roadmap to bioengineer plants that produce their own nitrogen fertilizer      (via sciencedaily.com)     Original source 

Nitrogen fertilizers make it possible to feed the world's growing population, but they are also costly adn harm ecosystems. However, a few plants have evolved the ability to acquire their own nitrogen with the help of bacteria, and a new study helps explain how they did it, not once, but multiple times.

Cosmic wrestling match      (via sciencedaily.com)     Original source 

Our universe is around 13.8 billion years old. Over the vastness of this time, the tiniest of initial asymmetries have grown into the large-scale structures we can see through our telescopes in the night sky: galaxies like our own Milky Way, clusters of galaxies, and even larger aggregations of matter or filaments of gas and dust. How quickly this growth takes place depends, at least in today's universe, on a sort of wrestling match between natural forces: Can dark matter, which holds everything together through its gravity and attracts additional matter, hold its own against dark energy, which pushes the universe ever further apart?

A chemical claw machine bends and stretches when exposed to vapors      (via sciencedaily.com)     Original source 

Scientists have developed a tiny 'claw machine' that is able to pick up and drop a marble-sized ball in response to exposure to chemical vapors. The findings point to a technique that can enable soft actuators--the parts of a machine that make it move--to perform multiple tasks without the need for additional costly materials. While existing soft actuators can be 'one-trick ponies' restricted to one type of movement, this novel composite film contorts itself in different ways depending on the vapor that it is exposed to.
