A new device simulates the way in which the gastrointestinal tract absorbs orally-administ...

Before drugs are tested on humans, they first go through pre-clinical tests on animals. Because humans and animals don't have identical gastrointestinal tracts, however, the way in which the drugs are absorbed by the body often differs between the two. A scientist from the UK's University of Huddersfield hopes to address that discrepancy, with his "gut simulator."  Read More

A woman's skull has been successfully replaced with a 3D-printed implant

A 22-year-old woman has had the whole top of her skull replaced with a customized 3D-printed implant. The patient had been suffering from severe symptoms as a result of a condition that causes a thickening of the skull. It is believed that the procedure was the first of its kind.  Read More

The mini heart takes the form of a cuff of cardiac tissue, wrapped around a vein

When someone has chronic venous insufficiency, it means that because of faulty valves in their leg veins, oxygen-poor blood isn't able to be pumped back to their heart. The George Washington University's Dr. Narine Sarvazyan has created a possible solution, however – a beating "mini heart" that's wrapped around the vein, to help push the blood through.  Read More

The ATHENA organ project combines heart, liver, kidney and lung features in a toxicity tes...

A five-year, US$19 million multi-institutional effort is working on developing a "desktop human" that could reduce the need for animal testing in the development of new drugs. The "homo minitus" is a drug and toxicity analysis system that would comprise four human organ constructs interconnected to mimic the response of human organs. The project has now reported success in the development of its first organ construct, a human liver construct that responds to exposure to a toxic chemical much like a real liver.  Read More

Researchers have developed a technique that allows stem cells to be created from less than...

Harvesting samples for producing stem cells can be rather painful. Techniques can involve collecting large amounts of blood, bone marrow or skin scrapes. The reality is intrusive measures such as these can be very off-putting. But what if it was as simple as a finger-prick? Such a DIY approach, which is so easy it can be done at home or in the field without medical staff, has been developed by researchers at Singapore's A*STAR Institute of Molecular and Cell Biology (IMCB).  Read More

One of the EyeGo adapters, used for examining the retina

When it comes to thoroughly assessing the condition of someone's eyes, it's usually necessary to utilize large, expensive contraptions such as those found in an ophthalmologist's office. While that's OK in some situations, physicians in rural areas or developing nations might not have access to such technology. Additionally, emergency room personnel typically need information on-the-spot, ASAP. That's why two scientists from Stanford University have created the EyeGo system, which allows smartphones to do the job.  Read More

One of the new injectable pressure sensors

When people have nerve problems such as those caused by spinal injuries, they can lose the ability to feel when their bladder is full. This means that they don't know when it needs to be emptied, resulting in a build-up of pressure that can damage both the bladder and their kidneys. Now, a tiny sensor may offer a better way of assessing their condition, to see if surgery is required or if medication will suffice.  Read More

Protein from silkworm cocoons has been used to create strong yet biodegradable bone fixati...

Silk is an amazingly strong material, yet it also harmlessly biodegrades when left in the body. This has led to its use in experimental brain implants, heart patches, and even bio-electronics. According to a new study conducted by scientists at Tufts University School of Engineering and Beth Israel Deaconess Medical Center, it may now also find use in the production of better plates and screws used for securing broken bones.  Read More

Damaged or deformed ears could be rebuilt using the patient's own fat (Photo: Shutterstock...

Researchers at London's Great Ormond Street Hospital aim to grow a human ear via stem cells taken from a patient's fat tissue. Relatively little attention has been given to the reconstruction of damaged cartilage around the cranial area, however the new method is hoped to modernize this area of reconstructive surgery.  Read More

Illustrations of a human heart doing the left ventricular twist (left), and the Harvard mo...

When you think of a beating heart, you probably just picture it flexing in and out, sort of like a rubber ball being squeezed by an invisible hand. In fact, though, its motion is more similar to that of a dish rag being wrung out, with the top of the organ twisting in a clockwise direction while the bottom contracts counterclockwise. It's known as the left ventricular twist, and scientists have now replicated it using artificial muscles. The research could lead to better-functioning cardiac implants, among other things.  Read More
