​​​​​​​Noninvasive imaging could replace electrodes in epilepsy surgery planning

A noninvasive imaging method called virtual intracranial EEG (ViEEG) has been developed to replace electrodes in epilepsy surgery planning. The method uses magnetoencephalographic (MEG) imaging to create a dynamic map of the brain during seizures, enabling precise identification of brain networks involved in seizure generation.

Use of epidural in childbirth is linked to decreased severe maternal morbidity

A study of vaginal births in New York State hospitals found that labor neuraxial analgesia – having an epidural or combined spinal and epidural – was associated with a decreased risk of severe maternal morbidity. The use of epidural anesthesia was linked to a 14% reduction in the risk of severe maternal morbidity, with racial and ethni...

New approach enables background-suppressed tumor-targeted photoacoustic imaging

A research team has proposed a new approach to achieve background-suppressed tumor-targeted photoacoustic imaging, enabling deep-tissue tumor-specific imaging in vivo. The approach uses genetically engineered bacteria to deliver a photoswitchable chromoprotein to the tumor site, eliminating interference from blood background signals.

Evidence for exotic magnetic phase of matter

Researchers discovered a novel type of magnet, the antiferromagnetic excitonic insulator, which involves strong magnetic attraction between electrons in a layered material. The new state emerges when electrons form bound pairs with holes and trigger an antiferromagnetic alignment of adjacent electron spins.

Identification of new risk factors or early signs of Alzheimer's disease

Researchers analyzed health records of nearly 80,000 patients to identify new risk factors for Alzheimer's disease, including depression, anxiety, and hearing loss. The study found that these conditions were associated with an increased risk of developing Alzheimer's up to 15 years before the onset of symptoms.

MDI Biological Laboratory scientist identifies mechanism underlying ‘inflammaging’

Researchers at MDI Biological Laboratory discovered that age-related chronic inflammation is caused by disruption of chromatin architecture. This leads to misexpression of genes lacking CpG islands, resulting in inflammation and loss of cellular function. The findings provide a unifying theory for the age-related degenerative diseases.
