A new study by Prof. Gabriel Weimann, a senior researcher at the International Institute for Counter-Terrorism (ICT) at Reichman University and professor emeritus in the Department of Communication at the University of Haifa, and Daniel Haberfeld, a researcher and head of the Cyberterrorism Desk at ICT, explored the activities of the Handala hacker group, which is linked to Iran's Ministry of Intelligence and Security (MOIS). The study sought to determine whether the group's operations are best characterized as cyberterrorism or psychological warfare.

A new study demonstrates that honeybees can evaluate the reliability of their own communication, actively adjusting the vigor of their "waggle dance" based on the truthfulness of the information they provide. By manipulating whether a dancing bee's followers successfully found food, experiments revealed that only bees with verified, "honest" information increased their recruitment effort over time when advertising a new location, whereas "liar" or "unverified" bees did not. This internal self-control mechanism naturally filters out ambiguous or misleading signals, allowing the hive to function efficiently as a cooperative superorganism.

The vast majority of Europe's beaches offer "excellent" water quality for swimming, the EU environment agency said Tuesday ahead of the summer season, with coastal nations and inland Austria topping the list.

A rare daytime occultation will see a thin crescent moon pass directly in front of dazzling Venus on June 17.

Scientists have found that hidden health signals coating your cells could change medicine forever. The new study by Edith Cowan University (ECU) School of Medical and Health Sciences has shown sugar molecules in your body may reveal disease long before it's detected. The research, published in Nature Chemical Biology, shines a spotlight on glycans—tiny, complex sugar chains that coat your cells and proteins.

Astronomers using the U.S. National Science Foundation Very Large Array (NSF VLA) have found that when a supermassive black hole tears apart an unlucky star, the fireworks are not over when the first flash fades. Years after the initial outburst, many of these black holes "burp" out streams of material that slam into surrounding gas and glow in radio waves, giving the NSF VLA a front-row seat to how black holes grow and blast energy back into their galaxies.

Our expert was impressed with the looks and performance of this mirrorless APS-C Nikon. This excellent all-round performer is now at its best price this year

An international team of astronomers led by Camille Poitras, a Ph.D. student in the Faculty of Science and Engineering at Laval University, has produced the most detailed X-ray view ever obtained of the jet launched by the supermassive black hole in the galaxy M87. By combining observations from NASA's Chandra X-ray Observatory acquired between 2012 and 2025 with advanced image-processing techniques, the researchers were able to track the evolution of jet structures with unprecedented detail.

Communities around the world have adapted to live on the year-round frozen soil of frigid environments, such as in the Arctic. However, rising temperatures have introduced a new challenge: What happens when the ground under houses and roads begins to melt?

Brötchen (aka bread roll) is already everyone's favorite carb. The post Hallo Brötchen! Berlin Zoo welcomes baby pygmy hippo appeared first on Popular Science.

A new study by Prof. Avraham Faust of Bar-Ilan University's Department of General History presents new evidence that may shed light on one of the most debated questions in the study of Israelite religion: Did King Hezekiah's religious reforms actually occur, and did they transform religious practices throughout the Kingdom of Judah?

The Transient Artifact and Continuous Learning System (TACLS) leverages data from continuously operating satellite networks coupled with machine learning models to help meteorologists at the National Weather Service forecast flash floods more efficiently.

We often hear about glacier melting and predictions of what climate change could do. But very little is mentioned about the effects on ecosystems or the animals that call them home. To redress some of this imbalance, an international team of researchers set out to map this hidden biodiversity. Their findings are published in the Proceedings of the National Academy of Sciences.
