Blood Test Rapidly Detects Signs of Pancreatic Cancer

A new diagnostic test shows promise for detecting the disease earlier. The test, which is at the proof-of-concept stage, can rapidly screen a drop of blood for bio-markers of pancreatic...

Applying an Electric Field May Lead to More Resilient Dental Implants

Researchers have observed a way that the brittle nature of ceramics can be overcome as they sustain heavy loads, leading to more resilient structures such as dental implants.

Spider Silk Key to New Bone-Fixing Composite

Researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Cancer Blood Test Detects Tumors Early

A microfluidic device the size of two quarters has the ability to catch and release circulating tumor cells (CTCs) — cancer cells that circulate in a cancer patient's blood. Such a device could lead to...

Drug-filled, 3D Printed Dentures Fight Infections

Researchers have turned to 3D printers, using the machines to build dentures filled with microscopic capsules that periodically release Amphotericin B, an antifungal medication. A study...

Erasable Contrast Agents Blink On/Off

Researchers are working on “erasable” contrast agents that would have the ability to blink off, on command, thereby revealing their location in the body.

Prosthetic Arms Provide Controlled Sensory Feedback

Researchers have developed a control algorithm that regulates current so that a prosthetics user feels steady sensation, even when the electrodes begin to peel off or when sweat builds up.

Lab-on-a-Chip Delivers Critical Immunity Data for Vulnerable Populations

A team of researchers has developed a portable, reconfigurable lab-on-a-chip diagnostic platform and field-tested the system in remote Kenya. Their validated platform...

Hybrid Nanotech Device Mimics Blood-Brain Barrier

Researchers have fabricated an artificial device reproducing a 1:1 scale model of the blood-brain barrier (BBB), the anatomical and functional structure that protects the central nervous...

Noninvasive Wearable System Monitors Stomach Activity

A team of engineers and physicians has developed a wearable, noninvasive system to monitor electrical activity in the stomach over 24 hours — essentially an electrocardiogram but for the...

Engineers have for the first time demonstrated that wood can be directly converted into a carbon sponge capable of withstanding repeated compression and other extreme mechanical...

Mobile ELISA Gives Results at Point of Care

Researchers have created a mobile version of the Enzyme Linked Immunosorbent Assay (ELISA), the gold standard technique used to detect the presence of an antibody or antigen. Instead of sending...

Ferroelectric Material Improves Ultrasound

Development of a theoretical basis for ultrahigh piezoelectricity in ferroelectric materials has led to a new material with twice the piezo response of any existing commercial ferroelectric...

Paper-Folding Art Inspires Better Bandages

Engineers have developed a thin, lightweight, rubber-like adhesive film that can stick to highly deformable regions of the body, such as the knee and elbow, and maintain its hold even after 100...

A team of engineers has developed a prototype Li-ion battery that obtains both good flexibility and high-energy density. It allows remarkable flexibility, high energy...

Skin-Inspired Coating Can Heal Itself

Researchers often have to compromise between strength and the ability to self-repair when developing coating materials. Now one team has developed a smart coating that is as hard as tooth enamel on the...

Brain Pacemaker Shows Promise in Slowing Alzheimer’s

Researchers conducted a study aimed at slowing the decline of problem solving and decision-making skills in patients who suffer from Alzheimer’s disease.

Lighting the Way for Cancer Treatment

Photodynamic therapy (PDT) has largely been limited to surface cancers due to its inability to penetrate deeper than a centimeter of tissue. A new approach wirelessly delivers doses of light into deeper...

Tissue Paper Sensors Show Promise for Healthcare
