Heart surgery may seem like a standard procedure in this modern age, however, there is always a danger that the patient’s blood may coagulate or clot too quickly, both of … Continue Reading Light beam replaces blood tests during human heart surgery.
The basic human body plan, the arrangement of organs in the body, is laid down during embryonic development. Insight into the formation of this plan informs researchers re normal development … Continue Reading New 3D atlas of human embryonic growth clears up many misconceptions on development.
A strand of DNA is a very long, narrow string, just a few nanometers across. Single-molecule orientation measurements provide unparalleled insight into a multitude of biological and polymeric systems. Single-molecule … Continue Reading New imaging technique reveals unprecedented nanoscale details about DNA.
First discovered in 1975, carbon nanotubes are graphene sheets rolled up into cylinders. The diameter is typically in the nanometer range, and the length can be up to many micrometers. … Continue Reading Nanotubes light-up 3D location of cancer tumour.
Scientists have many tools at their disposal for looking at preserved tissue under a microscope in incredible detail, or peering into the living body at lower resolution. What they haven’t … Continue Reading Researchers develop first technique for viewing cells and tissues in 3D under the skin.
Envelope glycoprotein GP120 is a glycoprotein exposed on the surface of the HIV envelope (ENV). The envelope glycoprotein trimer is essential for HIV entry into cells as it plays a … Continue Reading New breakthrough imaging shows HIV structure in unprecedented detail.
Over the past century, the most reliable method of diagnosing diseases has been the microscopic visualization of thinly sectioned tissues mounted on glass slides. This practice of histopathology is universally … Continue Reading Pen-sized microscope which identifies cancer cells in the operating room, out of animal studies.
People with diabetes are more likely to have high blood pressure and high cholesterol and are much more likely to develop cholesterol blockages in their arteries. A person with diabetes … Continue Reading 3-D MRI can show stroke risk in diabetic patients even before narrowing of arteries.
Chronic total occlusion, the complete blockage of the coronary artery, represents a major challenge for cardiologists globally. The situation is driven by the unpredictable surgical success rates related to the … Continue Reading World’s first as virtual reality used to guide human coronary procedure.
There is tremendous interest in mapping all the neuron connections in the human brain with the ultimate goal to better understand how the billions of neurons in the brain communicate … Continue Reading Nanoparticles used to track the action potential of a single neuron for the first time.
Surgeons at The Children’s Hospital of Philadelphia (CHOP) joined with colleagues from Penn Medicine recently to complete the world’s first bilateral hand transplant on a child. Earlier this month, the … Continue Reading Surgeons perform the world’s first successful bilateral hand transplant on a child.
A multidisciplinary team of Vall d’Hebron University Hospital, led by Dr. Joan-Pere Barret, head of Plastic Surgery and Burns, have performed the world’s most complex successful face transplant. The team … Continue Reading Spanish hospital performs world’s most complex face transplant to-date.
For the first time researchers have imaged and linked live individual brain cells to specific basic behaviours.
Researchers at the UNC School of Medicine have used new deep-brain imaging techniques to link the activity of individual, genetically similar neurons to particular behaviours of mice. Specifically, for the … Continue Reading For the first time researchers have imaged and linked live individual brain cells to specific basic behaviours.
DNA sequences were once thought to be identical from cell to cell, but it’s increasingly understood that mutations can arise during brain development that affect only certain groups of brain … Continue Reading New single-cell sequencing technique can track subtle neurogenetic mutations spatially.
Researchers at Oregon State University have developed a new way to selectively insert compounds into cancer cells, a system that will help surgeons identify malignant tissues and then, in combination … Continue Reading Nanotechnology guides cancer surgery and then selectively kills remaining malignant cells.
