The same geometric quirk that lets visitors murmur messages around the circular dome of the whispering gallery at St. Paul's Cathedral in London or across St. Louis Union Station's whispering arch also enables the construction of high-resolution optical sensors. Whispering-gallery-mode (WGM) resonators have been used for decades to detect chemical signatures, DNA strands and even single molecules.

Stoners are not as lazy and unmotivated as stereotypes suggest, according to new U of T Scarborough research.

Pronouns like "he" and "she" are at the center of much debate as society tries to shift to using more gender-inclusive pronouns like "they"—especially when referring to those with identities that do not fit with traditional pronouns. Research at the University of New Hampshire looked at the use of pronouns in two different languages—including one where all pronouns are identity neutral—and found that people's use of pronouns reflects not just the language they speak but also their ideologies.

A technology has been developed to quickly convert livestock manure, a significant issue in animal farming, into valuable "black gold" rich in carbon within a day.

Climate change is significantly altering bioclimatic environments in China's dry–wet transition zones, according to a recent study published in the Journal of Hydrology.

A prevailing opinion in land management is that non-native invasive plants are of no ecological value and they significantly diminish habitat quality for wildlife. Conservation practitioners allocate significant resources to invasive plant removal, often relying on surrounding native plants to passively fill the void. However, evidence that this practice improves food abundance or quality for wildlife is surprisingly limited.

Platforms that offer rides to passengers, such as Uber and DiDi, thrive on socio-economic inequality. By modeling the behavior of passengers and self-employed drivers, researchers of TU Delft simulated the market for ridesourcing platforms, evaluating a broad spectrum of (in)equality levels in societies.

A group of archaeologists, led by researchers from the University of Tokyo, announce the discovery of a part of a Roman villa built before the middle of the first century. This villa, near the town of Nola in southwestern Italy's Campania region, was found beneath a more recent, but still ancient building from the 2nd century.

In the quantum world, processes can be separated into two distinct classes. One class, that of the so-called "perturbative" phenomena, is relatively easy to detect, both in an experiment and in a mathematical computation. Examples are plentiful: the light that atoms emit, the energy that solar cells produce, the states of qubits in a quantum computer.

Greening the way we eat needn't mean going vegetarian. A healthy, more realistic solution is to adopt a flexitarian diet where seafoods add umami to "boring" vegetables. University of Copenhagen gastrophysicist Ole G. Mouritsen puts mathematical equations to work in calculating the umami potential of everything from seaweed and shrimp paste to mussels and mackerel.

The case of a Florida bottlenose dolphin found with highly pathogenic avian influenza virus, or HPAIV—a discovery made by University of Florida researchers in collaboration with multiple other agencies and one of the first reports of a constantly growing list of mammals affected by this virus—has been published in Communications Biology.

Landslides are one of the most destructive natural disasters on the planet, causing billions of dollars of damage and devastating loss of life every year. By introducing a new paradigm for studying landslide shapes and failure types, a global team of researchers has provided help for those who work to predict landslides and risk evaluations.

Interface engineering has been proven to be effective in discovering new quantum states, such as topological states, superconductivity, charge density waves, magnetism, etc., which require atomic-scale heterostructure fabrication. Monolayer FeSe on SrTiO3 substrates has attracted intense interest owing to its remarkable interface-enhanced superconductivity.

Prof. Wu HengAn's team from the University of Science and Technology of China has presented six representative phases of amorphous carbons based on large-scale molecular dynamics (MD) simulations, achieving a comprehensive microstructural landscape of amorphous carbons.

PSW ecologist and tribal liaison Frank Lake wondered how the birds he grew up with in northeastern California were faring. As a Karuk tribal descendant with Yurok family, Lake has a deep connection to the land and the birds that inhabit it. Belted kingfishers, woodpeckers, condors, eagles, and other birds have been part of his ancestors' way of life for thousands of years.

With a federal subsidy that has provided less expensive or free broadband internet to more than 23 million American households due to run out of money by the end of May, a new University of Massachusetts Amherst study reveals that direct-to-consumer subsidies can be far more effective at connecting households to high-speed internet than expanding broadband infrastructure.

Whether you're trying to predict a climate catastrophe or mental health crisis, mathematics tells us to look for fluctuations.

Seventy thousand years ago, the sea level was much lower than today. Australia, along with New Guinea and Tasmania, formed a connected landmass known as Sahul. Around this time—approximately 65,000 years ago—the first humans arrived in Sahul, a place previously devoid of any hominin species.

Finding the best person to fill a position can be tough, from drafting a job ad to producing a shortlist of top interview candidates.

A ghost is haunting our universe. This has been known in astronomy and cosmology for decades. Observations suggest that about 85% of all the matter in the universe is mysterious and invisible. These two qualities are reflected in its name: dark matter.

Herds of endangered hippos stuck in the mud of dried-up ponds are in danger of dying in drought-struck Botswana, conservation authorities told AFP Friday.

In the last several decades, large forest fires have increasingly threatened communities across the Mediterranean. Climate change is expected to make these fires larger, hotter, and more dangerous in the future. But fire management lessons from the past could help to improve the resilience of local landscapes.

Emmanuelle Butty, med.vet., DACVIM (SAIM), assistant clinical professor at Cummings School of Veterinary Medicine, sometimes treats dogs with leptospirosis, an infection that can lead to kidney failure and even death.

While it can be hard for us to notice as we go about our busy lives, cities are filled with indigenous plants, fungi, insects, spiders and other little creatures, as well as birds, frogs and reptiles.

A collaborative research team from NIMS and Tokyo University of Science has successfully developed an artificial intelligence (AI) device that executes brain-like information processing through few-molecule reservoir computing. This innovation utilizes the molecular vibrations of a select number of organic molecules.
