Researchers have developed an optical biopsy system that can distinguish between cancerous and healthy liver tissue. The technology makes use of diffuse reflectance spectroscopy and lifetime fluorescence measurements to evaluate makers of cellular metabolism that differ between healthy and cancerous cells. The system has higher accuracy than traditional biopsies, possibly making liver cancer diagnosis easier.

A philosophy team analyzed the role self-deception plays in everyday life and the strategies people use to deceive themselves. The team described four strategies used to stabilize and shield the positive self-image. According to their theory, self-deception helps people to stay motivated in difficult situations.

Using data from over 300 patient tumors, researchers have described 12 classes of 'immune archetypes' to classify cancer tumors. Their findings reveal that cancers from different parts of the body are immunologically similar to one another. These classifications provide unique strategies for enhancing each patient's choice of cancer immunotherapies.

Researchers analyzed thousands of microglia from different brain regions of deceased patients who had been diagnosed with a variety of neuropsychiatric and neurodegenerative disorders. Their results support the idea that microglia may play critical roles in some cases of brain disease while also providing a potentially valuable guide for future studies.

An international team has made a significant breakthrough in understanding why Alzheimer's disease progresses so rapidly in some people that they die within three years. The researchers found a link between strains of misshapen and fast-replicating tau protein and accelerated cognitive decline -- a critical result that illuminates the variations in Alzheimer's disease and could help lead to more precise diagnoses and targeted therapies. Such work could lead to changes in Alzheimer's care, possibly giving patients and families more accurate prognoses.
Findings open the way to more precise diagnoses and treatments of Alzheimer’s disease

Standard chemotherapies may efficiently kill cancer cells, but they also pose significant risks to healthy cells, resulting in secondary illness and a diminished quality of life for patients. To prevent the previously unavoidable damage, researchers have developed a new class of nanomaterials engineered to capture chemotherapy drugs before they interact with healthy tissue.
