Artificial intelligence and machine learning technologies are poised to supercharge productivity in the knowledge economy, transforming the future of work. But they're far from perfect.

Machine learning (ML) - technology in which algorithms "learn" from existing patterns in data to conduct statistically driven predictions and facilitate decisions - has been found in multiple contexts to reveal bias. An example is Amazon.com coming under fire for a hiring algorithm that revealed gender and racial bias. Such biases often result from slanted training data or skewed algorithms.

Scientists at the U.S. Department of Energy's Ames Laboratory and their collaborators from Iowa State University have developed a new approach for generating layered, difficult-to-combine, heterostructured solids. Heterostructured materials, composed of layers of dissimilar building blocks display unique electronic transport and magnetic properties that are governed by quantum interactions between their structurally different building blocks, and open new avenues for electronic and energy applications.

To the general public, lasers heat objects. And generally, that would be correct.

But lasers also show promise to do quite the opposite -- to cool materials. Lasers that can cool materials could revolutionize fields ranging from bio-imaging to quantum communication.

Bereavement Care in the Wake of COVID-19: Offering Condolences and Referrals

During the morning of June 23, the fourth system in the Northern Atlantic Ocean was a subtropical depression. By the afternoon, the subtropical depression took on tropical characteristics and was renamed Dolly. NASA's Terra satellite greeted Tropical Storm Dolly by taking an image of the new tropical storm.

Sophia Antipolis - 23 June 2020: Microorganisms on the tongue could help diagnose heart failure, according to research presented today on HFA Discoveries, a scientific platform of the European Society of Cardiology (ESC).1

Scientists have found that man-made mercury pollution has reached the bottom of the deepest part of the ocean - the Marianas Trench. This has significant implications for how mercury affects the marine environment, and how it may be concentrated in the food chain. The findings, which come from two independent research groups, are presented at the Goldschmidt geochemistry conference.

The assassination of Julius Caesar on the Ides of March in 44 B.C.E. triggered a 17-year power struggle that ultimately ended the Roman Republic leading to the rise of the Roman Empire. To the south, Egypt, which Cleopatra was attempting to restore as a major power in the Eastern Mediterranean, was shook by Nile flood failures, famine, and disease. These events are among the best known and important political transitions in the history of western civilization. A new study reveals the role climate change played in these ancient events.

Microbubbles are used every day as contrast agents in medical sonography, and are the subject of intense research for the delivery of therapeutic agents. There are a number of options available to manipulate these microbubbles, including the use of light and sound, although the potential of the latter remains largely unexplored.

The artificial lighting which lines the world's coastlines could be having a significant impact on species that rely on the moon and stars to find food, new research suggests.

Creatures such as the sand hopper (Talitrus saltator) orientate their nightly migrations based on the moon's position and brightness of the natural night sky.

EVANSTON, Ill. -- Northwestern University researchers have developed a family of soft materials that imitates living creatures.

When hit with light, the film-thin materials come alive -- bending, rotating and even crawling on surfaces.

Called "robotic soft matter by the Northwestern team," the materials move without complex hardware, hydraulics or electricity. The researchers believe the lifelike materials could carry out many tasks, with potential applications in energy, environmental remediation and advanced medicine.

TORONTO - A simple but highly sensitive blood test has been found to accurately diagnose and classify different types of brain tumours, resulting in more accurate diagnosis, less invasive methods and better treatment planning for patients, in the future.

New research findings underline the crucial role that sea ice throughout the Southern Ocean played for atmospheric CO2 in times of rapid climate change in the past. An international team of scientists with the participation of the University of Bonn has shown that the seasonal growth and destruction of sea ice in a warming world increases the biological productivity of the seas around Antarctica by extracting carbon from the atmosphere and storing it in the deep ocean.

A new study from North Carolina State University suggests that people have more tolerance for wolves after seeing positive videos about them, which could make YouTube an important wolf conservation tool.

The powerful hurricane that struck Galveston, Texas on September 8, 1900, killing an estimated 8,000 people and destroying more than 3,600 buildings, took the coastal city by surprise.

This video looks at advances in hurricane forecasting in the 120 years since, with a focus on the contributions from weather satellites. This satellite technology has allowed us to track hurricanes - their location, movement and intensity.
