Using artificial intelligence applications to help craft a message to a friend is not a good idea -- at least if your friend finds out about the use of AI, a new study suggests.

Researchers who created a soft robot that could navigate simple mazes without human or computer direction have now built on that work, creating a 'brainless' soft robot that can navigate more complex and dynamic environments.

Synchronicity is all around us, but it is poorly understood. Computer scientists have now developed new tools to understand how human and natural networks fall in and out of sync.

A new artificial intelligence tool can help people with Parkinson's disease remotely assess the severity of their symptoms within minutes. While expert neurologists performed slightly better than the AI model, the AI model outperformed the primary care physicians with UPDRS certification.

A study shows nest temperatures affect leatherback hatchling shape, performance and nest success. Lower temperatures produced longer hatchlings; highest temperatures produced hatchlings with thicker body depths. Hatchlings from the highest nest temperatures had shorter flippers. Righting response (ability to flip over) scores were significantly lower in hatchlings from hotter nests. Hatchlings that were smaller and/or had a larger body depth struggled to right themselves. The leatherback turtle nests in this study also had an overall lower hatching success (45 percent) than loggerhead (73 percent) and green sea turtles (70 percent).

Right at the bottom of the deep sea, the first very simple forms of life on earth probably emerged a long time ago. Today, the deep sea is known for its bizarre fauna. Intensive research is being conducted into how the number of species living on the sea floor have changed in the meantime. Some theories say that the ecosystems of the deep sea have emerged again and again after multiple mass extinctions and oceanic upheavals. Today's life in the deep sea would thus be comparatively young in the history of the Earth. But there is increasing evidence that parts of this world are much older than previously thought.

A team of scientists developed a new machine learning model for discovering critical-element-free permanent magnet materials based on the predicted Curie temperature of new material combinations.

Digital information exchange can be safer, cheaper and more environmentally friendly with the help of a new type of random number generator for encryption. The researchers behind the study believe that the new technology paves the way for a new type of quantum communication.

An international team of marine scientists has studied the DNA of family groups from four different whale species to estimate their mutation rates. Using the newly determined rates, the group found that the number of humpback whales in the North Atlantic before whaling was 86 percent lower than earlier studies suggested.

A new technique can synchronize media streams from different networks to multiple devices with less than 10 milliseconds of delay. The technique was demonstrated on cloud gaming, but could also be applied in AR/VR applications.

The day when robots can cook dinner, clear the kitchen table and empty the dishwasher is still a long way off. First, robots need to be able to recognize the many items of different sizes, shapes and brands in our homes. A team has now made a significant advance toward that technology with a robotic system that uses artificial intelligence to help robots better identify and remember objects.

A soft ball designed to support mental health by 'personifying' breath has been invented by a computer science student.

We live in an analog world of continuous information flow that is both processed and stored by our brains at the same time, but our devices process information digitally in the form of discrete binary code, breaking the information into little bits (or bites). Researchers have revealed a pioneering technology that combines the potential of continuous analog processing with the precision of digital devices. By seamlessly integrating ultra-thin, two-dimensional semiconductors with ferroelectric materials, the research unveils a novel way to improve energy efficiency and add new functionalities in computing. The new configuration merges traditional digital logic with brain-like analog operations.

New research found that marine heat waves -- prolonged periods of unusually warm ocean temperatures -- haven't had a lasting effect on the fish communities that feed most of the world. The finding is in stark contrast to the devastating effects seen on other marine ecosystems cataloged by scientists after similar periods of warming, including widespread coral bleaching and harmful algal blooms.

Scientists believe a huge 14ft smalltooth sand tiger shark, which washed up at Kilmore Quay, Co. Wexford, earlier this year, represents the first of its species to have been found in Ireland's waters. Two other individuals of the same species also washed up on the UK coastline, suggesting this species' geographic range has shifted. The scientists believe these rare finds may offer a window into the future, with more and more species traditionally confined to more tropical waters expected to visit Irish and British waters.

A major red tide event occurred in waters off Southern California in the spring of 2020, resulting in dazzling displays of bioluminescence along the coast. Now, for the first time, a study has pinpointed how the plankton species Lingulodinium polyedra -- a dinoflagellate -- was able to create such an exceptionally dense bloom. The answer lies in dinoflagellates' remarkable ability to swim, which lends them a competitive advantage over other species of phytoplankton.

A team of computer scientists recently unveiled a prize-winning Python profiler called Scalene. Programs written with Python are notoriously slow -- up to 60,000 times slower than code written in other programming languages -- and Scalene works to efficiently identify exactly where Python is lagging, allowing programmers to troubleshoot and streamline their code for higher performance.

Researchers have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecules can take to change between different configurations. The observation method makes use of a quantum simulator, developed from research in quantum computing, and offers an example of how advances in quantum computing are being used to investigate fundamental science.
