Coronavirus: test that can detect pathogen in 5 minutes developed by Nobel Prize winner Jennifer Doudna

October 20th, 2020 at 12:24 pm » Comments Off

The research team was led by University of California, Berkeley’s Dr Jennifer Doudna, a joint winner of the 2020 Nobel Prize for chemistry. Photo: Reuters California-based researchers develop a test that can detect the coronavirus using gene-editing technology and a modified mobile phone camera. Mobile phones were used for ‘their robustness and cost-effectiveness, and the fact […]

Researchers create hand-held device for patients to read levels of cancer biomarker in their own blood

October 18th, 2020 at 5:13 pm » Comments Off

Newswise: Researchers create hand-held device for patients to read levels of cancer biomarker in their own blood Newswise — HAMILTON, ON, Oct. 8, 2020 — Researchers at McMaster and Brock universities have created the prototype for a hand-held device to measure a biomarker for cancer, paving the way for home-based cancer monitoring and to improve […]

Scientists claim to invent hydrogel that heals nerve damage

October 17th, 2020 at 3:09 pm » Comments Off

THEY SAY THE GEL CAN PROPAGATE NEURAL SIGNALS WHERE NERVES ARE INJURED. A team of doctors and engineers have developed a new hydrogel that they say might be able to repair nerve damage more quickly and reliably than any other methods. The hydrogel is essentially a porous and water-saturated material that can stretch, bend, and […]

Biochip innovation combines AI and nanoparticles to analyze tumors

October 16th, 2020 at 11:25 am » Comments Off

Electrical engineers, computer scientists and biomedical engineers at the University of California, Irvine have created a new lab-on-a-chip that can help study tumor heterogeneity to reduce resistance to cancer therapies. In a paper published today in Advanced Biosystems, the researchers describe how they combined artificial intelligence, microfluidics and nanoparticle inkjet printing in a device that […]

Neural network trained to control anesthetic doses, keep patients under during surgery

October 9th, 2020 at 11:40 am » Comments Off

To define how the world should look, neural networks are making up their own rules  Researchers demonstrate how deep learning could eventually replace traditional anesthetic practices. Academics from the Massachusetts Institute of Technology (MIT) and Massachusetts General Hospital have demonstrated how neural networks can be trained to administer anesthetic during surgery. Over the past decade, […]

Experimental cancer treatment destroys cancer cells without using any drugs

October 7th, 2020 at 11:33 am » Comments Off

One of the latest methods pioneered by scientists to treat cancer uses a Trojan horse sneak attack to prompt cancer cells to self-destruct – all without using any drugs. Key to the technique is the use of a nanoparticle coated in a specific amino acid called L-phenylalanine, one of several such acids that cancer cells […]

Researchers create bioink that delivers oxygen to 3D printed tissue cells

September 25th, 2020 at 12:37 pm » Comments Off

Tissue engineering or regeneration is the process of improving upon or replacing biological tissues by combining cells and other materials with the optimal chemical and physiological conditions in order to build scaffolds upon which new viable tissue can form. We’ve seen many examples of 3D printing being used to accomplish this task. The potential to […]

How CRISPR is tackling the troubling immune response that’s plagued gene therapy until now

September 23rd, 2020 at 10:38 am » Comments Off

One of the major challenges facing gene therapy — a way to treat disease by replacing a patient’s defective genes with healthy ones — is that it is difficult to safely deliver therapeutic genes to patients without the immune system destroying the gene, and the vehicle carrying it, which can trigger life-threatening widespread inflammation. Three […]

To repair a damaged heart, three cells are better than one

September 19th, 2020 at 12:33 am » Comments Off

  Cell therapy for cardiac regeneration, while promising, has been hampered by issues with long-term survival of the transplanted cells. Now, a technique that combines three different types of cells in a 3-D cluster could improve its efficacy in reducing scar tissue and improving cardiac function after a heart attack. Called CardioCluster, the bioengineering technique […]

Cryogenic 3Dprinting improves bioprinting for bone regeneration

September 18th, 2020 at 12:23 am » Comments Off

  Researchers from China continue in the quest to improve methods for bone regeneration, publishing their findings in “Cryogenic 3D printing of dual-delivery scaffolds for improved bone regeneration with enhanced vascularization.” A wide range of projects have emerged regarding new techniques for bone regeneration—especially in the last five years as 3D printing has become more […]

This tiny robot tank could one day help doctors explore your intestine

September 11th, 2020 at 11:27 am » Comments Off

With a bulky, armored appearance, heavy duty treads for gripping, and a claw arm on the front, the Endoculus robot vehicle looks like it belongs on the battlefield. In fact, it’s just 3 cm wide, 2.3 cm tall, and designed for an entirely different kind of inhospitable environment: Your intestine. “[This] robotic capsule endoscope, Endoculus, […]
