If you are one of the millions of women identified as having dense breasts, your healthcare team may recommend supplemental or additional screening to check your breasts for cancer. Dr. Kristin Robinson, a breast radiologist at Mayo Clinic, says there are several options when it comes to these screening tests. She recommends working closely with […]
Raman image of rapidly frozen HeLa cells with high signal-to-noise ratio and large field-of-view. The image acquisition time was 10 hours. The distribution of Raman signals from cytochromes (750 cm⁻¹), lipids (2850 cm⁻¹), proteins (2920 cm⁻¹), are indicated in green, red, and blue, respectively. Credit: Science Advances (2024).

Our vector mapping includes the local real-space detection of the orientation of the altermagnetic order vector, L = M1 − M2with respect to the MnTe crystal axes in the (0001)-plane by X-ray magnetic linear dichroism (XMLD)-PEEM, and of the sign of L for a given crystal orientation by including X-ray magnetic circular dichroism (XMCD)-PEEM. In antiferromagnets with opposite spin […]
Breaking loss symmetry in coupled resonant emitters to enhance thermal imaging contrast. Credit: Communications Engineering (2024). DOI: 10.1038/s44172-024-00316-y A team of Rice University scientists has solved a long-standing problem in thermal imaging, making it possible to capture clear images of objects through hot windows. Imaging applications in a range of fields—such as security, surveillance, industrial […]

Schematic of the experimental approach. Credit: IMP, from Physical Review Letters (2024). DOI: 10.1103/PhysRevLett.133.193002 A new study published in Physical Review Letters and led by researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) has demonstrated that a Coulomb explosion induced by highly charged ions is a unique tool […]
Take a stroll down any major beach and it likely won’t be long before you stumble upon some abandoned refuse. Old water bottles, trash bags, straws, and countless other variations of plastic scrap litter the world’s beaches, eventually making their way into the ocean where they degrade over the course of decades or even centuries. […]
Mayo Clinic remains a leader in healthcare innovation, applying advanced technologies like the 7-Tesla MRI to help improve patient care. This imaging system uses a stronger magnetic field to produce more detailed images of the body’s interior. Dr. Justin Cramer, a Mayo Clinic neuroradiologist, explains how detailed brain scans help Mayo Clinic care teams diagnose […]
