3D-Printed Robotic Arm for Sign Language Translation

Mon, 21 Aug 2017 16:25:48 +0000

A team of engineers at the University of Antwerp in The Netherlands has developed a 3D-printed robotic arm that can act as a sign language translator for deaf people. Sign language interpreters are often in short supply, and so this research team set out to develop a low cost automated system that can translate text […]



Deep Sequencing of Loose DNA in Blood for Early Detection of Many Cancers

Mon, 21 Aug 2017 13:58:21 +0000

A collaborative project between scientists in the U.S., Denmark, and The Netherlands has developed a way of spotting bits of DNA in blood that derive from tumors deep in the body. The technology may allow for early detection of cancers before any symptoms arise and earlier than any other existing approach. Though the fact that tumors […]



Growing and Testing Drugs on Dozens of Tiny Guts at Once

Fri, 18 Aug 2017 17:37:10 +0000

In a demonstration of where the field of organ-on-a-chip technology is inevitably going, MIMETAS, a company developing organ-on-chip technology out of Leiden, The Netherlands, and Roche, the giant pharmaceutical company, teamed up to grow and test 350 perfused gut tubes within a matter of days. The gut tubes replicate the basic structure of an intestine and […]



Gold Nanostars and Immunotherapy Combined for a Cancer Vaccine

Fri, 18 Aug 2017 17:12:40 +0000

Researchers at Duke University have combined an FDA approved immunotherapy and a gold nanostar/laser treatment to completely eradicate tumors and vaccinate against the cancer. The team’s technique involves injecting gold nanoparticles into the bloodstream. These star-shaped nanoparticles (nanostars) can accumulate in tumors after circulating within the blood. Then the tumor is blasted with a laser, […]



Stimulating the Brain with Magnetic Fields Can Control Movement

Thu, 17 Aug 2017 16:57:11 +0000

Scientists have developed a method to stimulate small clusters of brain cells using magnetic fields. Using this technique, they were able to control movement in mice. Understanding how the brain works is an ongoing effort, with a huge number of research teams working intensively to unlock its secrets. As part of this effort, an international […]



Micromotors Powered by Stomach Acids Lower pH, Safely Release Antibiotics

Thu, 17 Aug 2017 15:36:20 +0000

Researchers at University of California San Diego have developed tiny micromotors that propel themselves around the stomach, neutralizing the acids within, eventually releasing a cargo of drugs once the pH is at a desired level. This approach can change how antibiotics and other pH sensitive drugs are delivered, as currently proton pump inhibitors have to […]



New Material to Help Repair Brain Tissue Damaged by Stroke

Wed, 16 Aug 2017 19:47:26 +0000

One of the reasons why strokes are so devastating is that brain tissue does not exhibit the same healing mechanisms as other tissues that repair themselves quickly. Integrin proteins are responsible for some of the healing processes, including getting new cells to move and having them adhere to the extracellular matrix, and these are not strongly […]



Miniature Bioengineered Vessels to Study Progeria Therapies

Wed, 16 Aug 2017 19:20:34 +0000

Progeria is a rare but deadly disorder that is commonly known as an early aging disease, bringing forth conditions in children that are normally only reserved for older adults. To better study how to fight progeria, a disease that significantly affects the cardiovascular system, researchers at Duke University have developed a way to grow tiny […]



New Optical Tool to Spot Nerves During Surgery

Wed, 16 Aug 2017 18:28:40 +0000

A team of medical researchers has come up with a way to optically spot nerves within tissue, which should prevent nerve injuries that can happen during surgeries of the hand and other sensitive and delicate parts of the body. The technology uses something called collimated polarized light imaging (CPLi) and by rotating the polarization, one is […]



Silver Nanoparticle Coating and Tiny Electric Current Prevent Bacteria from Settling on Medical Devices

Wed, 16 Aug 2017 17:01:05 +0000

Silver ions and electric current are well known killers of bacteria that have been utilized to keep things clean in different scenarios for many years. Yet, their use is limited to only certain applications as a fairly high current or potentially toxic concentration of silver ions are needed to destroy bacterial buildup. At the Karolinska Institutet in […]



SOZO High End Bioimpedance Spectroscopy System Being Released

Wed, 16 Aug 2017 16:27:25 +0000

ImpediMed, a company with offices in California and Australia, is releasing its new SOZO bioimpedance spectroscopy system that performs advanced body composition analysis. The technology involves sending out electric current through the arms and legs and detecting how the body affects it as it passes through. Though this technology has been in existence for a […]
