Arrays of quantum rods could enhance TVs or virtual reality devices

Posted by in categories: biotech/medical, nanotechnology, quantum physics, virtual reality

Flat screen TVs that incorporate quantum dots are now commercially available, but it has been more difficult to create arrays of their elongated cousins, quantum rods, for commercial devices. Quantum rods can control both the polarization and color of light, to generate 3D images for virtual reality devices.

Using scaffolds made of folded DNA, MIT engineers have come up with a new way to precisely assemble arrays of quantum rods. By depositing quantum rods onto a DNA scaffold in a highly controlled way, the researchers can regulate their orientation, which is a key factor in determining the polarization of light emitted by the array. This makes it easier to add depth and dimensionality to a virtual scene.

“One of the challenges with quantum rods is: How do you align them all at the nanoscale so they’re all pointing in the same direction?” says Mark Bathe, an MIT professor of biological engineering and the senior author of the new study. “When they’re all pointing in the same direction on a 2D surface, then they all have the same properties of how they interact with light and control its polarization.”

Fast Facts on Precision Medicine: Research on Myositis, an Inflammatory Disease

Posted by in category: biotech/medical

About 10% of people living with myositis—a rare inflammatory disease in which the immune system attacks healthy muscle cells—also are at risk for developing cancer. Determining which patients need screening and close follow-up is difficult.

“We screen a lot of people aggressively, and possibly unnecessarily,” says rheumatologist Christopher Mecoli, M.D., M.H.S., director of research operations and physician lead for the Myositis Precision Medicine Center of Excellence. This can lead to potential harms for patients such as radiation exposure, anxiety and false-positive test results that indicate a person has cancer when they actually do not.

ChatGPT diagnoses ER patients ‘like a human doctor’: Study

Posted by in categories: biotech/medical, robotics/AI

The chatbot’s reasoning was “at times medically implausible or inconsistent, which can lead to misinformation or incorrect diagnosis, with significant implications,” the report noted.

The scientists also admitted some shortcomings with the research. The sample size was small, with 30 cases examined. In addition, only relatively simple cases were looked at, with patients presenting a single primary complaint.

It was not clear how well the chatbot would fare with more complex cases. “The efficacy of ChatGPT in providing multiple distinct diagnoses for patients with complex or rare diseases remains unverified.”

Imprisoned scientist who gene-edited babies wanted to transform the human species

Posted by in categories: bioengineering, biotech/medical, genetics, law enforcement

The idea that genetic modification can improve humanity isn’t new, but it has taken some interesting turns within the scientific community over the past few years. One of the most notable comes from the mind of He Jiankui, a Chinese scientist whose gene editing of human babies led to infamy and a prison sentence. Now, He, known as JK to friends, thinks that gene-edited humans could be the future of our species.

Estimating life expectancy based on the age of type 2 diabetes diagnosis

Posted by in category: biotech/medical

Similarly, individuals who were diagnosed with diabetes at the age of 40 years died ten years earlier, and those diagnosed at the age of 50 died six years earlier than their healthy counterparts.

A robust association was established between earlier age of diabetes diagnosis and deaths due to vascular and non-neoplastic conditions. Common vascular diseases include stroke and myocardial infarction, while non-neoplastic conditions include neurological, respiratory, and infectious diseases.

The association between life expectancy and diabetes was marginally greater in women than in men. Compared to older adults, higher hazard ratios for mortality were associated with earlier age of diabetes detection.
