On a warm evening in May, swifts scream over rooftops, chasing insects above the traffic. A fox slips along a garden wall while gulls squabble on a supermarket roof. We tend to treat these animals as visitors. But they

Unlike Wi-Fi or cellular signals, millimeter-wave wireless communication channels are unable to pass through walls, furniture or other objects. This reality is part of what is holding back the implementation of millimeter-wave wireless, which is of great interest for 6G wireless systems and beyond because of its extremely large data-carrying capacity.

Robots sorting parcels and serving fried chicken enthralled visitors at a robotics expo in Beijing on Wednesday, where hundreds of companies set out their pitches for a future labor market transformed by artificial intelligence.

Adoptions are on hold for thousands of dogs and cats in Texas, potentially putting the animals at risk of being euthanized, because of efforts to stop the spread of the New World screwworm, an insect that has crossed the border from Mexico into the United States for the first time in 60 years.

Standing on the sandy, windswept shores of Provincetown, Massachusetts, people may find themselves squinting at the horizon, waiting for a whale to make its grand entrance with a spectacular breach.

Researchers from the National University of Singapore (NUS) have developed a method to turn waste from the tough, lightweight composites used in aircraft and other high-performance structures into aerogels that could be used for thermal insulation, sound absorption and oil spill cleanup.

Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are omega-3 fatty acids known to have beneficial effects and are popular as functional foods and dietary supplements. They are polyunsaturated fatty acids (PUFAs); the primary source of these PUFAs for humans is fish oil.

As they build their nests, many birds are known to interweave dried grasses and other materials with green plants, such as fresh leaves, grass stems, herbs and aromatic leaves. While this behavior is well documented, why many bird species choose to add fresh plants has remained unclear.

A new study published in the Biophysical Journal reports on the development of a stable, biologically active version of the human fibroblast growth factor. Human fibroblast growth factor, or FGF, has potent wound-healing and antidiabetic properties that could prove useful in the development of new therapeutics.

Niobium-94, an isotope of niobium with 41 protons and 53 neutrons, is a critical crossroads in the complex nuclear processes that forge heavy elements under the intense pressures and temperatures of dying stars. In an article published in Physical Review Letters, the n_TOF Collaboration reports the first-ever measurement of the probability of niobium-94 taking one of the paths at this crossroads

Decommissioning pipelines used by the oil and gas industry could result in substantial quantities of microplastics being released into the UK

The booming smartphone industry has spawned an enormous market in health-related mobile phone applications, with apps related to dieting making up about 12% of the market. The apps use persuasive systems design, including direct and indirect routes that persuade users to change their behavior.

The rules of tag are simple enough for a playground: catch or be caught. But when the players are autonomous drones, the game becomes a test of machine learning, split-second decision-making and cooperative strategy.

Simultaneous belief in logically incompatible claims is linked to conspiratorial thinking, according to a study that models belief using a Bayesian framework.
