Phys.org / InN thin films show transient Pauli blocking for broadband ultrafast optical switching
Recent decades have witnessed rapid advancements in high-intensity laser technology. The combination of laser irradiation and novel materials is opening exciting avenues for the design of functional materials and devices. ...
Phys.org / Cellular switch casts light on why humans are active in the day
Early mammalian ancestors were nocturnal, sleeping during the day while the dinosaurs dominated the land. However, some mammalian lineages, including human ancestors, independently transitioned to diurnality (active during ...
Phys.org / Most lab testing quietly inflates 2D transistor performance, research reveals
For nearly two decades, two-dimensional (2D) semiconductors have been studied as a complement or possible successor to silicon transistors, promising smaller, faster and more energy-efficient processors. To ease their production ...
Phys.org / From trash to climate tech: Rubber gloves find new life as carbon capturers
Every year, over 100 billion nitrile rubber gloves are produced. They are made from synthetic polymers—a material chemically related to plastic and derived from crude oil. The vast majority is used in the health care sector, ...
Phys.org / Satellite data enable first global estimate of aerosol cloud cooling
Particles in the atmosphere, known as aerosols, cool the climate by acting as cloud condensation nuclei. The more cloud droplets form around these particles, the less sunlight penetrates a cloud. This cools the climate, although ...
Phys.org / Fossil amber reveals the secret lives of Cretaceous ants
Tiny insects trapped in amber could tell us a great deal about their roles in past ecosystems: pollinators, parasites, predators, and prey. But how many of the insects preserved alongside each other reflect interactions during ...
Phys.org / Beam-spin asymmetry study puts proton models to the test
Getting an up-close view of life at the cellular level can be as simple as placing onion skin under a microscope and adjusting the knobs. Peering deeper, into the heart of the atoms within, isn't as easy. It requires peeling ...
Phys.org / Assessment of rare 'teenage' planetary system deepens understanding of cosmic evolution
Planetary systems such as our solar system take hundreds of millions of years to evolve. Since humanity has only existed for a sliver of that time, astronomers have only observed planetary systems at birth or, more often, ...
Phys.org / Genetic discovery could lead to faster growing duckweed
Duckweed is the fastest-growing flowering plant, but new knowledge of duckweed genetics discovered by Adelaide University researchers could lead to even faster growing rates. The research team, led by Professor Nikolai Borisjuk ...
Phys.org / Why tropical cyclones' rainfall surges before landfall
A research team at The Hong Kong University of Science and Technology (HKUST) has analyzed 40 years of data covering about 1,500 tropical cyclones and discovered that average rain rates surge by more than 20% in the 60 hours ...
Phys.org / AI toolkit turns microscopy images into multi-feature microstructure datasets
A research team from The Hong Kong University of Science and Technology (HKUST) has developed GrainBot, an AI-enabled toolkit that automatically extracts and quantifies multiple microstructural features from microscopy images. ...
Phys.org / A study in stardust: Massive binary stars emit tiny carbon particles
Yale junior Donglin Wu leads a new study showing that some of the biggest stars in the universe shed some of the smallest dust particles. It's fitting that Wu's first major scientific journal article as lead author focuses ...
