New research on 175,000 women—the largest NHS study to date—on the use of AI in breast cancer screening shows that AI detected more cases of invasive cancer, more cases overall, had fewer false positives, and recalled fewer women having their first scan than humans did. For one part of the study, AI reduced the time spent reading scans by almost a third.
Researchers at Utrecht University have quantitatively mapped the three-dimensional structure of photonic supraparticles for the first time. Supraparticles are microscopic spheres composed of thousands of smaller colloidal particles. Until now, researchers could only examine the outer surface of these structures. Using a combination of super-resolution microscopy and machine learning, the team shows that particles that appear disorganized on the outside are often almost perfectly crystalline on the inside.
The paper is published in the journal Advanced Materials.
Blue morpho butterflies owe their vibrant color to the internal structure of their wings, rather than pigment. The arrangement of particles on a microscopic scale causes light to be reflected in such a way that the butterflies appear intensely blue, and that the color looks the same from every viewing angle.
By controlling magnetic fields using light, a team of researchers led by NTU scientists has solved a long-standing challenge to precisely direct electric currents produced by quantum materials. Their findings unlock new avenues for controlling the flow of electricity through such materials and could herald the age of energy-efficient quantum computing devices. The research is published in Nature in January.
Like water moving through lakes and rivers, electrons in electric currents encounter resistance when flowing through electronic devices. This resistance generates large amounts of heat, which poses a problem for large computing facilities such as data centers and quantum computers, incurring major costs for cooling.
With artificial intelligence driving the demand for more computing applications, there is a need to produce electricity that flows without resistance to avoid generating excessive amounts of heat. These “free-flowing” electric currents could pave the way for novel low-power electronics and new quantum computing technologies.

Artificial intelligence (AI) is changing the field and practice of medicine, including legal liability and the perception of who is at fault when a patient experiences harm. “AI holds promise to improve the quality and safety of health care and to reduce errors and patient harm, but the risk of legal liability is a potential barrier for investment and development of this technology as well as the quality of care,” said Michael Bruno, professor of radiology and of medicine at Penn State College of Medicine.
Now, Bruno, working alongside a team of researchers from Brown University and Seton Hall University School of Law, found that the understanding of physician liability is influenced by the way in which AI is integrated into a clinician’s workflow. The study was published in the journal Nature Health.
The researchers presented mock jurors with a hypothetical malpractice case where a patient suffered irreversible brain damage because a radiologist didn’t detect a brain bleed from a computerized tomography (CT) scan, even though AI correctly identified the scan as abnormal.
Can AI become conscious?
What is consciousness for? And is biological consciousness best understood as a self-organising algorithm that could, in principle, be recreated in machines?
In this talk, Joscha explores consciousness as perception of perception, coherence maintenance, modelling, resonance, self-organisation, and the possibility that machine consciousness may emerge through the right virtual architecture.
