Researchers have incorporated an innovative ultra-broadband, quantum-entangled light source that generates a relatively wide range of infrared photons with wavelengths between 2 m and 5 m for dramatically downsizing the infrared spectroscopy system and upgrading its sensitivity. It can obtain spectra for various target samples, including hard solids, plastics, and organic solutions. This new technique uses the unique properties of quantum mechanics -- such as superposition and entanglement -- to overcome the limitations of conventional techniques.

People who were more skeptical of human-caused climate change or the Black Lives Matter movement who took part in conversation with a popular AI chatbot were disappointed with the experience but left the conversation more supportive of the scientific consensus on climate change or BLM. This is according to researchers studying how these chatbots handle interactions from people with different cultural backgrounds.

Chemists have developed an autonomous chemical synthesis robot with an integrated AI-driven machine learning unit. Dubbed 'RoboChem', the benchtop device can outperform a human chemist in terms of speed and accuracy while also displaying a high level of ingenuity. As the first of its kind, it could significantly accelerate chemical discovery of molecules for pharmaceutical and many other applications.

The branch of mathematics known as topology has become a cornerstone of modern physics thanks to the remarkable -- and above all reliable -- properties it can impart to a material or system. Unfortunately, identifying topological systems, or even designing new ones, is generally a tedious process that requires exactly matching the physical system to a mathematical model. Researchers have demonstrated a model-free method for identifying topology, enabling the discovery of new topological materials using a purely experimental approach.

Certain materials have desirable properties that are hidden and scientists can use light to uncover these properties. Researchers have used an advanced optical technique, based on terahertz time-domain spectroscopy, to learn more about a quantum material called Ta2NiSe5 (TNS).

Computer scientists have invented a highly effective, yet incredibly simple, algorithm to decide which items to toss from a web cache to make room for new ones.

Researchers grew a twisted multilayer crystal structure for the first time and measured the structure's key properties. The twisted structure could help researchers develop next-generation materials for solar cells, quantum computers, lasers and other devices.

The way trees grow together do not resemble how branches grow on a single tree, scientists have discovered.

From misinformation and invisible cyber attacks, to irresponsible AI that could cause events involving multiple deaths, expert futurists have forecast how rapid technology changes may shape our world by 2040.

A new advancement in theoretical physics could, one day, help engineers develop new kinds of computer chips that might store information for longer in very small objects.

Researchers have presented a new study on cyberattack risks to offshore wind farms in Glasgow, United Kingdom. They looked specifically at wind farms that use voltage-source-converter high-voltage direct-current (VSC-HVDC) connections, which are rapidly becoming the most cost-effective solution to harvest offshore wind energy around the world. They found that their complex, hybrid-communication architecture presents multiple access points for cyberattacks.

Human pathologists are extensively trained to detect when tissue samples from one patient mistakenly end up on another patient's microscope slides (a problem known as tissue contamination). But such contamination can easily confuse artificial intelligence (AI) models, which are often trained in pristine, simulated environments, reports a new study. Each of the four AI models in the study paid too much attention to the tissue contamination, which resulted in errors when diagnosing or detecting vessel damage, gestational age, lesions and prostate cancer, the study found.

Researchers have published a strategy for identifying new targets for immunotherapy through artificial intelligence (AI).

Researchers find that utilizing a unique AI algorithm that monitors several patient variables, like vital signs and lab results, can detect sepsis before symptom onset.

IntelliGenes analyzes genomic data to discover biomarkers associated with health traits.

A research team announced they have identified the principle by which musical instincts emerge from the human brain without special learning using an artificial neural network model.

Web 3.0 is a blockchain technology-based internet paradigm that is transparent and decentralized. But, Web 3.0 streaming services require modifications to the existing service structure due to certain technical issues. Now, researchers propose 'Retriever,' an Inter-Planetary File System (IPFS) based Web 3.0 technology and non-fungible token marketplace. The proposed marketplace reduces service delay and improves user experience by deploying their own IPFS nodes and controlling the blockchain.

A newly published study provides guidance for building accurate mathematical models for gene regulatory networks.

A new study outlines progress toward making bulk ferroelectric and antiferroelectric hafnia available for use in a variety of applications, including high-performance computing.

Researchers have developed a new, more environmentally friendly way to create conductive inks for use in organic electronics such as solar cells, artificial neurons, and soft sensors. The findings pave the way for future sustainable technology.
