Spaser Can Detect, Kill Circulating Tumor Cells to Prevent Cancer Metastases, Study Finds

Stockman-242x300.jpeg

A nanolaser known as the spaser can serve as a super-bright, water-soluble, biocompatible probe capable of finding metastasized cancer cells in the blood stream and then killing these cells, according to a new research study.

Researchers Report Link Between Cells Associated with Aging and Bone Loss

Mayo Clinic researchers have reported a causal link between senescent cells – the cells associated with aging and age-related disease – and bone loss in mice. Targeting these cells led to an increase in bone mass and strength. The findings appear online in Nature Medicine.

When Fish Swim in the Holodeck

Behavior experiments are useful tools to study brain function. Standard experiments to investigate behavior in popular lab animals such as fish, flies or mice however only incompletely mimic natural conditions. The understanding of behavior and brain function is thus limited. Virtual Reality (VR) helps in generating a more natural experimental environment but requires immobilization of the animal, disrupting sensorimotor experience and causing altered neuronal and behavioral responses. Researchers at the University of Freiburg, and the Max F. Perutz Laboratories (MFPL), a joint venture of the University of Vienna and the Medical University of Vienna, in collaboration with groups at the Research Institute of Molecular Pathology (IMP) and the MPI for Ornithology in Konstanz, have now developed a VR system for freely moving animals – FreemoVR – to overcome most of these limitations. Their findings are now published in Nature Methods.

New Bioimaging Technique Is Fast and Economical

IntesNature.jpg

A new approach to optical imaging makes it possible to quickly and economically monitor multiple molecular interactions in a large area of living tissue – such as an organ or a small animal; technology that could have applications in medical diagnosis, guided surgery, or pre-clinical drug testing.

Researchers Create Molecular Movie of Virus Preparing to Infect Healthy Cells

A research team has created for the first time a movie with nanoscale resolution of the three-dimensional changes a virus undergoes as it prepares to infect a healthy cell. The scientists analyzed thousands of individual snapshots from intense X-ray flashes, capturing the process in an experiment at the Department of Energy’s SLAC National Accelerator Laboratory.

Researchers Working on Blood Test to Detect Brain Metastases While Still Treatable

Houston Methodist cancer researchers are now closer to creating a blood test that can identify breast cancer patients who are at increased risk for developing brain metastasis, and also monitor disease progression and response to therapy in real time.

Multicolor MRIs Could Aid Disease Detection

Researchers at Case Western Reserve University School of Medicine have developed a method that could make magnetic resonance imaging—MRI—multicolor. Current MRI techniques rely on a single contrast agent injected into a patient’s veins to vivify images. The new method uses two at once, which could allow doctors to map multiple characteristics of a patient’s internal organs in a single MRI. The strategy could serve as a research tool and even aid disease diagnosis.
