How to make online arguments productive

1 day 10 hours ago
Researchers worked with almost 260 people to understand online disagreements and to develop potential design interventions that could make these discussions more productive and centered around relationship-building.

Water and quantum magnets share critical physics

6 days 8 hours ago
Water can freeze from liquid to solid ice or boil into a gas. In the kitchen these 'phase transitions' aren't smooth, but their discontinuous nature is smoothed out at high pressure. An international team of physicists has now discovered the same behavior in certain quantum magnets, which may have consequences for the technology of qubits.

New approach to centuries-old 'three-body problem'

1 week ago
The "three-body problem," the term coined for predicting the motion of three gravitating bodies in space, is essential for understanding a variety of astrophysical processes as well as a large class of mechanical problems, and has occupied some of the world's best physicists, astronomers and mathematicians for over three centuries. Their attempts have led to the discovery of several important fields of science; yet its solution remained a mystery.

People may trust computers more than humans

1 week ago
Despite increasing concern over the intrusion of algorithms in daily life, people may be more willing to trust a computer program than their fellow humans, especially if a task becomes too challenging, according to new research from data scientists.

A molecule that responds to light

1 week ago
Light can be used to operate quantum information processing systems, e.g. quantum computers, quickly and efficiently. Researchers have now significantly advanced the development of molecule-based materials suitable for use as light-addressable fundamental quantum units. They have demonstrated for the first time the possibility of addressing nuclear spin levels of a molecular complex of europium(III) rare-earth ions with light.

A breakthrough that enables practical semiconductor spintronics

1 week 5 days ago
It may be possible in the future to use information technology where electron spin is used to store, process and transfer information in quantum computers. It has long been the goal of scientists to be able to use spin-based quantum information technology at room temperature. Researchers have now constructed a semiconductor component in which information can be efficiently exchanged between electron spin and light at room temperature and above.

Scientists harness chaos to protect devices from hackers

1 week 6 days ago
Researchers have found a way to use chaos to help develop digital fingerprints for electronic devices that may be unique enough to foil even the most sophisticated hackers. Just how unique are these fingerprints? The researchers believe it would take longer than the lifetime of the universe to test for every possible combination available.

Screening for skin disease on your laptop

2 weeks ago
A biomedical engineer is reporting a new deep neural network architecture - to be used on a standard laptop - that provides early diagnosis of systemic sclerosis (SSc), a rare autoimmune disease marked by hardened or fibrous skin and internal organs.

Deep learning networks prefer the human voice -- just like us

2 weeks ago
A study proves that AI systems might reach higher levels of performance if they are programmed with sound files of human language rather than with numerical data labels. The researchers discovered that in a side-by-side comparison, a neural network whose 'training labels' consisted of sound files reached higher levels of performance in identifying objects in images, compared to another network that had been programmed in a more traditional manner, using simple binary inputs.

A new, positive approach could be the key to next-generation, transparent electronics

2 weeks 1 day ago
A new study could pave the way to revolutionary, transparent electronics for potential integration in glass, flexible displays and smart contact lenses -- bringing to life futuristic 'scifi-like' devices. A decades-long search for electronics based on semiconducting oxides could also find use in power electronics and communications, reducing the carbon footprint of our utility networks. The introduction of a new 2D semiconductor fills a crucial gap in the materials spectrum to enable fast, transparent circuits.

A robot that senses hidden objects

2 weeks 5 days ago
RF Grasp is a picking robot that combines vision with radio frequency (RF) sensing to find and grasps objects, even if they're hidden from view. The technology could aid fulfillment in e-commerce warehouses.
