Software could 3D print organ replicas on demand

Software could 3D print organ replicas on demand
Erica Endicott was pregnant with her son, Kaden, when cardiologists at Phoenix Children’s Heart Center discovered that the left side of the boy’s heart was not growing properly. Kaden, who is healthy now, was treated by a team of doctors in Boston for the life-threatening condition. Following the procedure, they used data from an ultrasound system to create and print 3D models of Kaden’s heart before and after his surgery.

Stretching the limits of neural implants

Stretching the limits of neural implants
Implantable fibres have been an enormous boon to brain research, allowing scientists to stimulate specific targets in the brain and monitor electrical responses. But similar studies in the nerves of the spinal cord, which might ultimately lead to treatments to alleviate spinal cord injuries, have been more difficult to carry out. That’s because the spine flexes and stretches as the body moves, and the relatively stiff, brittle fibres used today could damage the delicate spinal cord tissue.

Text-mining tool turbocharges biomedical pursuits

Text-mining tool turbocharges biomedical pursuits
With about 100 lines of code, a Morgridge Institute for Research team has unleashed a fast, simple and predictive text-mining tool that may turbocharge big biomedical pursuits such as drug repurposing and stem cell treatments. The algorithm, named “KinderMiner” by its inventors, has been put to use exploring one of the largest single archives of research journal papers, Europe PubMed Central.

3D printing produces model blood vessels

3D printing produces model blood vessels
Creating model blood vessels to aid in the study of diseases, such as strokes, can be complicated, costly and time-consuming. And the results may not always be truly representative of a human vessel. Assistant Professor Pranav Soman and his research team have engineered a new method to create model blood vessels that is more efficient, less expensive and more exact.

'Synthetic skin' could lead to advanced prosthetic limbs

'Synthetic skin' could lead to advanced prosthetic limbs
Engineers from the University of Glasgow, who have previously developed an 'electronic skin' covering for prosthetic hands made from graphene, have found a way to use some of graphene's remarkable physical properties to use energy from the sun to power the skin. Graphene is a highly flexible form of graphite which, despite being just a single atom thick, is stronger than steel, electrically conductive, and transparent.

Artificial lung works as bridge to transplants

Artificial lung works as bridge to transplants
Each year, nearly 350,000 Americans die of some form of lung disease, with another 150,000 patients needing short- and long-term care. Unfortunately, current breathing-support technologies are cumbersome, often requiring patients to be bedridden and sedated. Now, with the support of a $3.4 million National Institutes of Health grant, researchers at the University of Pittsburgh will develop an artificial lung to serve as a bridge to transplant or recovery in patients with acute and chronic lung failure.

Engineer aims to grow spinal tissue in lab

Engineer aims to grow spinal tissue in lab
For a soldier who suffered a spinal cord injury on the battlefield, the promise of regenerative medicine is to fully repair the resulting limb paralysis. But that hope is still years from reality. Not only powerful, but efficient. Studying diseases in lab-created tissue may help reduce the price tag — now roughly $1.8 billion — for bringing a new drug to market, which is one of the reasons Ashton received a National Science Foundation CAREER Award for advancing tissue engineering of the human spinal cord.

Wirelessly powered implants suit miniature cardiac pacing

Wirelessly powered implants suit miniature cardiac pacing
As implantable devices continue to shrink, the race is on for similarly-sized reliable power sources. Current state-of-the art implantables often depend on chunky batteries that suffer from limited lifetimes, with a typical pacemaker battery lasting around eight years. While some techniques have successfully harvested power from biological processes such as heart beats or from body heat, most devices require significantly more energy.

Plant-based 3D scaffolds can create biomedical implants

Plant-based 3D scaffolds can create biomedical implants
  Borrowing from nature is an age-old theme in science. Form and function go hand-in-hand in the natural world and the structures created by plants and animals are only rarely improved on by humans.

Tethered nanoparticles make tumour cells more vulnerable

Tethered nanoparticles make tumour cells more vulnerable
MIT researchers have devised a way to make tumour cells more susceptible to certain types of cancer treatment by coating the cells with nanoparticles before delivering drugs. By tethering hundreds of tiny particles to the surfaces of tumour cells in the presence of a mechanical force, the researchers made the cells much more vulnerable to attack by a drug that triggers cancer cells to commit suicide.
