Published Orchids support seedlings through 'parental nurture' via shared underground fungal networks
(via sciencedaily.com)
Original source 
Orchid plants nurture their seedlings via an underground fungal network, new research has revealed.
Published New technique offers more precise maps of the Moon's surface
(via sciencedaily.com)
Original source 
A new study may help redefine how scientists map the surface of the Moon, making the process more streamlined and precise than ever before.
Published Study is step towards energy-efficient quantum computing in magnets
(via sciencedaily.com)
Original source 
Researchers have managed to generate propagating spin waves at the nanoscale and discovered a novel pathway to modulate and amplify them. Their discovery could pave the way for the development of dissipation free quantum information technologies. As the spin waves do not involve electric currents these chips will be free from associated losses of energy. The rapidly growing popularity of artificial intelligence comes with an increasing desire for fast and energy efficient computing devices and calls for novel ways to store and process information. The electric currents in conventional devices suffer from losses of energy and subsequent heating of the environment.
Published Slugs and snails love the city, unlike other animals
(via sciencedaily.com)
Original source 
Most native species avoid more urbanized areas of Los Angeles, but slugs and snails may actually prefer these environments, according to a new study.
Published The secret sex life of coral revealed
(via sciencedaily.com)
Original source 
Corals play an essential role in ocean ecosystems, and like many organisms, they are under threat from climate change and other human activities. To better protect coral, it's first necessary to understand them, in particular their reproductive life cycle, which only happens once a year. For the first time, researchers have produced a model for coral spawning, based on various environmental factors. They achieved this by tapping an often overlooked source of aquatic knowledge, an aquarium.
Published How killifish embryos use suspended animation to survive over 8 months of drought
(via sciencedaily.com)
Original source 
The African turquoise killifish lives in ephemeral ponds in Zimbabwe and Mozambique. To survive the annual dry season, the fish's embryos enter a state of extreme suspended animation or 'diapause' for approximately 8 months. Now, researchers have uncovered the mechanisms that enabled the killifish to evolve this extreme survival state.
Published Entomologist sheds light on 250-year-old mystery of the German cockroach
(via sciencedaily.com)
Original source 
Entomologists have solved the 250-year-old origin puzzle of the most prevalent indoor urban pest insect on the planet: the German cockroach. The team's research findings, representing the genomic analyses of over 280 specimens from 17 countries and six continents, show that this species evolved some 2,100 years ago from an outdoor-living species in Asia.
Published Observing mammalian cells with superfast soft X-rays
(via sciencedaily.com)
Original source 
Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or quadrillionths of a second. With this they could capture images of carbon-based structures in living cells for the first time, before the soft X-ray radiation damaged them.
Published More than spins: Exploring uncharted territory in quantum devices
(via sciencedaily.com)
Original source 
Many of today's quantum devices rely on collections of qubits, also called spins. These quantum bits have only two energy levels, the '0' and the '1'. However, spins in real devices also interact with light and vibrations known as bosons, greatly complicating calculations. Researchers now demonstrate a way to describe spin-boson systems and use this to efficiently configure quantum devices in a desired state.
Published How a tiny device could lead to big physics discoveries and better lasers
(via sciencedaily.com)
Original source 
Researchers have fabricated a device no wider than a human hair that will help physicists investigate the fundamental nature of matter and light. Their findings could also support the development of more efficient lasers, which are used in fields ranging from medicine to manufacturing.
Published Innovative material for sustainable building
(via sciencedaily.com)
Original source 
Researchers introduce a polymer-based material with unique properties. This material allows sunlight to enter, maintains a more comfortable indoor climate without additional energy, and cleans itself like a lotus leaf. The new development could replace glass components in walls and roofs in the future.
Published Renewable grid: Recovering electricity from heat storage hits 44% efficiency
(via sciencedaily.com)
Original source 
Closing in on the theoretical maximum efficiency, devices for turning heat into electricity are edging closer to being practical for use on the grid, according to new research.
Published Sexual parasitism helped anglerfish invade the deep sea during a time of global warming
(via sciencedaily.com)
Original source 
Members of the vertebrate group including anglerfishes are unique in possessing a characteristic known as sexual parasitism, in which males temporarily attach or permanently fuse with females to mate. Now, researchers show that sexual parasitism arose during a time of major global warming and rapid transition for anglerfishes from the ocean floor to the deep, open sea.
Published New discoveries about the nature of light could improve methods for heating fusion plasma
(via sciencedaily.com)
Original source 
Scientists have made discoveries about light particles known as photons that could aid the quest for fusion energy.
Published Scientists learn how to control muscles with light
(via sciencedaily.com)
Original source 
Researchers developed a way to help people with amputation or paralysis regain limb control. Their optogenetic technique could offer more precise control over muscle contraction, along with a dramatic decrease in muscle fatigue.
Published Australian study proves 'humans are planet's most frightening predator'
(via sciencedaily.com)
Original source 
A new study demonstrates that kangaroos, wallabies and other Australian marsupials fear humans far more than any other predator.
Published 'Fossilizing' cracks in infrastructure creates sealing that can even survive earthquakes
(via sciencedaily.com)
Original source 
In a new study, a team of researchers used research on fossilizing techniques to create a new method for sealing cracks and fractures in rocks and bedrock using a 'concretion-forming resin'. This innovative technique has applications in a wide range of industries, from tunnel construction to long-term underground storage of hazardous materials.
