Researchers have succeeded in developing a technique to quickly search for the optimal quantum gate sequence for a quantum computer using a probabilistic method.

Generative artificial intelligence and social media can undermine efforts to address climate change, argue researchers in a new forum article published in the journal Global Environmental Politics.

Do people learn from their failures? In a new study, researchers have examined the high-stakes field of cardiothoracic surgery to assess the relationship between individuals' experiences with failures and the learning outcomes associated with them. The study found that individuals reach a threshold at which they stop learning from their failures and that this threshold is higher for surgeons with a higher perceived ability to learn.

As the U.S. Environmental Protection Agency cracks down on insidious "forever chemical" pollution in the environment, military and commercial aviation officials are seeking ways to clean up such pollution from decades of use of fire suppressant foams at military air bases and commercial airports.

UC Riverside astrophysicist Stephen Kane had to double-check his calculations. He wasn't sure the planet he was studying could be as extreme as it seemed.

Communities with higher-than-average illegal market opportunities (proxied by drug-related activities) are more likely to be targeted by organized crime groups, a new study shows.

The implementation of integrated optical switches shows promise in the size reduction of ROADMs for greater flexibility and compactness, ultimately leading to robust single-chip solutions. Despite decades of research on switches with various structures and platforms, achieving a balance between dense integration, low insertion loss (IL), and polarization-dependent loss (PDL) remains a significant challenge.

Is it worth the effort to seek high status in a group or setting for which a person has no real passion? New Cornell research suggests the answer is "no."

The feathered limbs, sharp teeth and claws of the oldest known bird-like dinosaurs, the Archaeopteryx have fascinated naturalists and paleontologists including Charles Lyell and Charles Darwin who propelled the species to fame especially following publication of his theory of evolution.

The upcoming launch of the Φsat-2 mission is a prime example of the pioneering work that ESA does in the field of AI in Earth observation.

Commentators link America's declining birth rate to a number of factors: a lack of support for mothers in the workplace, expensive child care, delayed marriage and a rising cost of living.

In 1916, a road up the hill to Fausland farm on the island of Hitra was being upgraded, using gravel from the shore along the innermost part of Barmfjorden. Suddenly, the workers noticed some human bones in between all the sand and stones. The bones belonged to a man who was approximately 25 years of age and who had died at the very end of the Stone Age—4,000 years ago.

Under blue skies, officials at Florida's largest power company dealt Thursday with the aftermath of a major hurricane that slammed into Miami and Fort Lauderdale—or a pretend one, anyway.

The effects of space weather extend out across our entire solar system, but this is a simulation of where everything starts: the sudden, violent, emergence of a "flux rope" out of the sun's magnetic field and into the solar wind. In the process flux ropes may bring along millions of tons of plasma from the solar surface to be released into space, known as a Coronal Mass Ejection, or CME.

With pulses of sound through tiny speakers, Cornell physics researchers have clarified the basic nature of a new superconductor.

DNA analysis by Queensland Museum scientists has unearthed the true identity of 15 species of land snails including four new-to-science species with one named in honor of Queensland wildlife warrior Robert Irwin.

The demand for high pixel-count, low-cost focal-plane arrays in the near-infrared (NIR) and short-wavelength infrared (SWIR) spectra has surged due to their potential applications in AI-driven technologies such as 3D face-identification, augmented/virtual reality, robotics, and autonomous vehicles. Traditional SWIR photodiodes rely on crystalline germanium (Ge) or indium gallium arsenide (InGaAs), which have limitations including high dark current and complex fabrication processes. The advent of... Читать дальше...

Marine ecosystem-based management (EBM) is a growing practice of ocean stewardship and conservation that offers benefits to the production of healthy, local food and the preservation of clean water, as well as recreation, habitation and storm protection in the Gulf of Maine and beyond.

Superfast levitating trains, long-range lossless power transmission, faster MRI machines—all these fantastical technological advances could be in our grasp if we could just make a material that transmits electricity without resistance—or "superconducts"—at around room temperature.

Current methods to count plastic pollution in rivers are insufficient and do not account for the fragments that sink below the surface, a team of scientists has warned.

A study published in the open-access journal NeoBiota reveals UK residents' complex perceptions of the ring-necked parakeet (Psittacula krameri), an introduced species now prevalent across various urban and rural settings in the country.

April continued the year's warm streak, with 2024 ranking as the fifth-warmest year on record for the nation so far.

Every resident of the West Midlands lives in an area exceeding the World Health Organization's air quality guidelines, and air pollution in the region is causing up to 2,300 premature deaths each year according to new research.

There are high rates of harassment behaviors within the obstetrics and gynecology (OB-GYN) specialty, according to a review published online May 8 in JAMA Network Open.

An international team of researchers has discovered that the quantum particles responsible for the vibrations of materials—which influence their stability and various other properties—can be classified through topology.
