Organo-metal Compound Kills Cancer Cells from Inside
The compound is said to be 50 times more active than the conventional cancer drug Cisplatin and more discriminating between healthy cells and cancer cells.
Solar-Powered Eye (and Ear) Exams
A low-cost, solar-powered ophthalmoscope was developed at University of St. Andrews, Scotland, to help health workers in low-income countries detect signs of blindness.
Safer Brain Surgery with Smart Needle
A brain biopsy needle houses a miniature fiber-optic camera, allowing surgeons to avoid at-risk vessels during instrument insertion and prevent potentially fatal bleeds.
Cheap Chips May Expand Access to Medical Diagnostics
An inkjet-printed lab-on-a-chip that costs about a penny to produce could revolutionize diagnostic services around the world.
Engineers Tap Stomach Acid to Power Tiny Sensors
The system can generate enough power to run sensors or drug delivery devices that can reside in the gastrointestinal tract for extended periods of time.
A 3-D Bioprinter Prints Human Skin
The final product replicates the natural structure of human skin and might be used to test consumer chemical products, as well as for medical transplants.
Arming Surgical Masks to Kill Viruses
A salt coating applied to a surgical mask filter dissolves upon exposure to virus aerosols and recrystallizes during drying, destroying the pathogens.
Temperature-Sensitive Artificial Skin
The material could be used on prosthetic devices to sense temperature change or as a bandage that would alert a nurse or doctor about a developing infection in a wound.
Retinal Vein Surgery by Robot
Researchers turned to robotics technology developed a device that enables needle insertion into the veins in a precise, stable way.
Detecting Arthritis with Aerospace Technology
The subsonic sound of cracking in people’s joints might be tracked by a skin patch based on airplane acoustic emission sensors.
OSHA Finalizes Beryllium Exposure Rule
The new rule revises previous beryllium permissible exposure limits, which were based on decades-old studies.
Soft Robot Wraps Failing Hearts
A soft robotic sleeve twists and compresses in synch with a beating heart, augmenting cardiovascular functions weakened by heart failure.
Skin Patch for Smarter Insulin Delivery
A microneedle-array patch monitors and automatically responds to blood glucose levels.
Open-Source Biosignal Acquisition Device
The Bluetooth data acquisition device has a special focus on bio-signals such as ECG, EMG, and EEG.
Wearable Sensors That Measure Dehydration
The device is lightweight, flexible, and stretchable and has already been incorporated into prototype devices that can be worn on the wrist or as a chest patch.
Scientists Aim to Make Tomatoes Taste Good Again
Researchers wanted to identify why modern tomato varieties are deficient in flavor chemicals. They determined that it’s because they have lost the more desirable alleles of a number of genes.
Treating Water with Engineered Floating Wetlands
Engineered floating wetlands can treat water and provide refuge for fish, birds, and insects.
Modular Valve Simplifies Diagnostic Chip Fabrication
Rapid and cheap on-the-spot diagnoses for diseases such as tuberculosis and cancer are a step closer thanks to a new modular valve for microfluidic chips.
Smart Glasses That Focus on What You Are Looking At
When the wearer looks at an object, a meter measures the distance and tells the actuators how to curve the lenses. The lenses can change focus in 14 milliseconds.
Implant Material Repels Blood
A titanium surface that’s extremely repellent to blood could form the basis for surgical implants which reduce the risk of rejection by the body.
