Multistep mechanism of nanostructure formation in liquid crystal
Most of our daily commodities, such as plastics, alloys and processed foods, are provided as solids, and they are often processed by a controlled cooling process from a liquid mixture to a solid. Liquid crystals, solutions, polymers, and biomaterials.....»»
Nutrients direct intestinal stem cell function and affect aging, finds study
Researchers at the University of Helsinki have discovered a new mechanism of action between the nutrient adaptation of intestinal stem cells and aging. The finding may make a difference when seeking ways to maintain the functional capacity of the agi.....»»
The dynamics of deformable systems: Study unravels mathematical mystery of cable-like structures
Are our bodies solid or liquid? We all know the convention—that solids maintain their shapes, while liquids fill the containers they're in. But often in the real world, those lines are blurred. Imagine walking on a beach. Sometimes the sand gives w.....»»
Which came first: Black holes or galaxies?
Black holes not only existed at the dawn of time, they birthed new stars and supercharged galaxy formation, a new analysis of James Webb Space Telescope data suggests......»»
Hubble spies baby stars being born amid chaos of interacting galaxies
Amid swirling gas and dust pulled by gravitational forces of interacting galaxies, there can be bursts of star formation, creating new generations of stars......»»
Results from South Pole Telescope"s new camera emerge
For more than five years, scientists at the South Pole Telescope in Antarctica have been observing the sky with an upgraded camera. The extended gaze toward the cosmos is picking up remnant light from the universe's early formation. Now researchers h.....»»
Mimas" surprise: Tiny moon holds young ocean beneath icy shell
Hidden beneath the heavily cratered surface of Mimas, one of Saturn's smallest moons lies a secret: a global ocean of liquid water. This astonishing discovery, led by Dr. Valéry Lainey of the Observatoire de Paris-PSL and published in the journal Na.....»»
Understanding jasmonic acid: A switch that activates autophagy in Arabidopsis petals
Organogenesis, an important aspect of flowering, helps reveal key processes of plant development such as the formation of floral organs, attainment of reproductive capability, and abscission leading to seed and fruit development......»»
Q&A: Research visualizes a precise mechanism for how cells sort their trash
For decades it has been an open question in the ubiquitin research field how proteins are labeled as being defective or unneeded. In a recent study Brenda Schulman, Director at the Max Planck Institute (MPI) of Biochemistry, and Gary Kleiger, Chair o.....»»
Enrichment of anchoring sites via supramolecular halogen bonds for efficient perovskite nanocrystal LEDs
Colloidal semiconductor nanoparticles can be viewed as a complex of an inorganic single crystal core and a monolayer of organic ligands. The location and type of ligand anchoring on the nanocrystal surface are critical to the nanocrystal morphology,.....»»
Newly discovered carbon monoxide-runaway gap can help identify habitable exoplanets
The search for habitable exoplanets involves looking for planets with similar conditions to the Earth, such as liquid water, a suitable temperature range and atmospheric conditions. One crucial factor is the planet's position in the habitable zone, t.....»»
NASA tests new spacecraft propellant gauge on lunar lander
It's easy to measure fuel in tanks on Earth, where gravity pulls the liquid to the bottom. But in space, the game changes. Quantifying fuel that's floating around inside a spacecraft's tank isn't so simple......»»
Multi-dimensional multiplexing optical secret-sharing framework with cascaded liquid crystal holograms
Information security has become particularly crucial under the background of the big data era. Optical secret-sharing schemes encrypt information and physically divide it into different shares. Information can only be decrypted by cascading a suffici.....»»
Secondary eyewall formation in upper- and lower-layer vertical wind shear simulated in idealized tropical cyclones
About 80% of intense tropical cyclones (TCs) possess concentric eyewalls—namely, the primary and secondary eyewalls. The intensity of the TC can vary considerably during secondary eyewall formation (SEF) and eyewall replacement, posing a great chal.....»»
Study challenges classical view of the Antarctic Circumpolar Current origin and warns of its vulnerability
The Circumpolar Current works as a regulator of the planet's climate. Its origins were thought to have caused the formation of the permanent ice in Antarctica about 34 million years ago. Now, a study led by the University of Barcelona, the Instituto.....»»
Preclinical study uncovers two proteins" crucial role in causing cancer cell growth
Scientists at City of Hope, one of the largest cancer research and treatment organizations in the United States, have discovered a new cellular mechanism that plays an important role in cancer cells' ability to cause disease. The study is published i.....»»
Team discovers mechanism that protects tissue after faulty gene expression
A study at the University of Cologne's CECAD Cluster of Excellence in Aging Research has identified a protein complex that is activated by defects in the spliceosome, the molecular scissors that process genetic information. Future research could lead.....»»
How did life get started on Earth? Atmospheric haze might have been the key
A recent study accepted to The Planetary Science Journal and currently posted to the arXiv preprint server investigates how the organic hazes that existed on Earth between the planet's initial formation and 500 million years afterwards, also known a.....»»
Researchers uncover source rocks of the first real continents
Geoscientists have uncovered a missing link in the enigmatic story of how the continents developed—a revised origin story that doesn't require the start of plate tectonics or any external factor to explain their formation. Instead, the findings pub.....»»
The moon is shrinking, causing moonquakes at the lunar south pole
New research from NASA suggests that the shrinking of the moon over time is causing moonquakes and the formation of faults near its south pole......»»
ALMA observations: Researchers reveal dynamic view of massive protocluster evolution
