Current AI risks more alarming than apocalyptic future scenarios

14 hours 28 min ago
Most people generally are more concerned about the immediate risks of artificial intelligence than they are about a theoretical future in which AI threatens humanity. A new study reveals that respondents draw clear distinctions between abstract scenarios and specific tangible problems and particularly take the latter very seriously.

Study shows addressing working memory can help students with math difficulty improve word problem-solving skills

Mon, 04/21/2025 - 1:31pm
Working memory is like a mental chalkboard we use to store temporary information while executing other tasks. Scientists worked with more than 200 elementary students to test their working memory, assess its role in word-problem solving and if interventions could boost it and thereby improve their word problem solving skills. Results showed that improving working memory helped both students with and without math difficulties and can help educators more effectively by helping teach the science of math, study authors argue.

High-tech sticker can identify real human emotions

Mon, 04/21/2025 - 1:28pm
Saying one thing while feeling another is part of being human, but bottling up emotions can have serious psychological consequences like anxiety or panic attacks. To help health care providers tell the difference, a team has created a stretchable, rechargeable sticker that can detect real emotions -- by measuring things like skin temperature and heart rate -- even when users put on a brave face.

Pushing boundaries: Detecting the anomalous Hall effect without magnetization in a new class of materials

Fri, 04/18/2025 - 8:26am
An international research team has discovered the anomalous Hall effect in a collinear antiferromagnet. More strikingly, the anomalous Hall effect emerges from a non-Fermi liquid state, in which electrons do not interact according to conventional models. The discovery not only challenges the textbook framework for interpreting the anomalous Hall effect but also widens the range of antiferromagnets useful for information technologies.

Curved neutron beams could deliver benefits straight to industry

Thu, 04/17/2025 - 11:49am
Scientists have created the first neutron 'Airy beam,' which has unusual capabilities that ordinary neutron beams do not. The achievement could enhance neutron-based techniques for investigating the properties of materials that are difficult to explore by other means. For example, the beams can probe characteristics of molecules such as chirality, which is important in biotechnology, chemical manufacturing, quantum computing and other fields.

RoboBee comes in for a landing

Wed, 04/16/2025 - 12:19pm
A recently created RoboBee is now outfitted with its most reliable landing gear to date, inspired by one of nature's most graceful landers: the crane fly. The team has given their flying robot a set of long, jointed legs that help ease its transition from air to ground. The robot has also received an updated controller that helps it decelerate on approach, resulting in a gentle plop-down.
