Researchers have demonstrated a new way of attacking artificial intelligence computer vision systems, allowing them to control what the AI “sees.” The research shows that the new technique, called RisingAttacK, is effective at manipulating all of the most widely used AI computer vision systems.

At issue are so-called “adversarial attacks,” in which someone manipulates the data being fed into an AI system to control what the system sees, or does not see, in an image. For example, someone might manipulate an AI’s ability to detect traffic signals, pedestrians or other cars—which would cause problems for autonomous vehicles. Or a hacker could install code on an X-ray machine that causes an AI system to make inaccurate diagnoses.

New high-resolution images of protoplanetary disks in the Ophiuchus star-forming region, created with improved analysis. The resolution is shown by the white ellipse in the lower left of each panel, with a smaller ellipse indicating higher resolution. The white line in the lower right of each panel indicates a scale of 30 au. The evolution stage of the central stars progresses from left to right, and from top to bottom in the same row.

In a stellar nursery 460 light-years away, astronomers sharpened old ALMA data and spotted crisp rings and spirals swirling around 27 infant stars—evidence that planets start taking shape just a few hundred thousand years after their suns ignite, far earlier than anyone expected.

Signs of planet fo...

Research led by the National Institute of Biological Sciences in Beijing has discovered that switching on a single dormant gene enables mice to regenerate ear tissue.

Some vertebrates such as salamanders and fish can regenerate complex tissue structures with precision. A lost limb can be regrown, a damaged heart or eye can be repaired. Salamanders are so remarkable at reconstructing damaged tissues that even a spinal cord injury with severed neural motor connectivity can be restored.

Mammals occasionally showcase the ability to regenerate. Deer antlers and goat horns are examples of living tissue regeneration. Mice can regrow fingertips if they are lost. A healthy human liver can experience up to 70% loss of tissue and regrow to near full size within several weeks.

However, f...

A research team from the University of Wollongong’s (UOW) Institute for Superconducting and Electronic Materials (ISEM) has addressed a 40-year-old quantum puzzle, unlocking a new pathway to creating nextgeneration electronic devices that operate without losing energy or wasting electricity.

Published in Advanced Materials, the study is the work of UOW researchers led by Distinguished Professor Xiaolin Wang and Dr. M Nadeem, with Ph.D. candidate Syeda Amina Shabbir and Dr. Frank Fei Yun.

It introduces a new design concept to realize the elusive and highly sought-after quantum anomalous Hall (QAH) effect.

The field of quantum materials could cut global energy consumption and transform everyday life for people around the world.

Using a technique called entropy engineering, t...
