Improving 3D Printing of Fine Structures in Artificial Tissue
The biggest challenge in tissue printing is the achievement of sufficient control over small scale structure to produce a vasculature that can supply the tissue as it develops. Without that capacity, tissue growth is limited to thin sheets and tiny organoids. Advances have been made in recent years, such as the work of Volumetric, but there is still a way to go before large tissue sections are regularly generated for use in medicine. This is in large part why work on decellularization continues to proceed apace, taking donor tissue and stripping the cells from it to leave the extracellular matrix structure, with all of its...

“An important part of being in science is being in a community,” says Neil Garg, Ph.D., Distinguished Professor and chair of the department of chemistry and biochemistry at the University of California Los Angeles (UCLA). That philosophy has led him to prioritize mentorship, diversity, and inclusion—while maintaining research excellence—as well as re-envisioning what it means to educate students and the public.
Falling in Love With Chemistry
Science was always a part of Dr. Garg’s childhood. He participated in science fairs as a kid but says he did it for the commun...

Fight Aging! Newsletter, February 13th 2023
This study investigated whether taller Polish adults live longer than their shorter counterparts. Data on declared height were available from 848,860 individuals who died in the years 2004-2008 in Poland. To allow for the cohort effect, the Z-values were generated. Separately for both sexes, Pearson's r coefficients of correlation were calculated. Subsequently, one way ANOVA was performed.
The correlation between adult height and longevity was negative and statistically significant in both men and women. After eliminating the effects of secular trends in height, the correlation was very weak (r = -0.0044 in men and ...

Considering a Role for Infectious Disease in the Evolution of Aging
If interested in the evolution of aging, today's open access paper opens with a very readable tour of the history of thought on this topic, as well as the more recent debate between different classes of hypotheses that seek to explain the evolution of aging. The authors are opinionated, and the path leads to their favored theory, involving population-wide effects driven by infectious disease that do not require group selection, but it nonetheless covers a lot of ground and makes for an educational read. Theories of aging are much debated, perhaps in part because there are so many exceptions to the rule that must be explain...

A Career Launched Through “Transformative” NIGMS-Funded Training Programs
Dr. Brenda Andrade. Credit: Courtesy of Dr. Brenda Andrade.
Brenda Andrade, Ph.D., assistant professor at California State University, Los Angeles (CSULA), wasn’t sure what she wanted to do when she first started community college. Through a program at her high school, she’d participated in Saturday morning science labs on the CSULA campus, and that introduction to science led her to think about pursuing some sort of scientific degree. She recalls flipping through the course catalog to the list of science classes needed to transfer to a 4-year university, and “naively going down the list and taking them.”

Artificial Neuron Uses Ions Like the Real Thing
Researchers at Linköping University in Sweden have developed artificial neurons that demonstrate 15 of the 20 characteristics of biological neural cells and can communicate with natural neurons in the body. The researchers call their device the “conductance-based organic electrochemical neuron,” or c-OECN, and it is based on materials that can conduct a negative charge, including organic electrochemical transistors and n-type conducting polymers. By printing thousands of such transistors on a flexible substrate, the researchers have been able to create artificial neurons. The device uses ions to control the fl...

Reducing Viral Spread in Schools: France Makes Proactive Move to Measure and Reduce CO2 Levels in School and Daycare
One of my favorite gadgets from the pandemic is the AraNet 4 CO2 monitor. I carry it with me whenever I am curious about an indoor space. This easy-to-use monitor gives a simple red-yellow-green reading of the CO2 level. At a green level (<1000 ppm) it is harder to transmit an airborne viral infection. At a red level (>1400 ppm) it is much easier to catch a virus if someone else in the room is sick.
I use this in restaurants and on airplanes, for instance, to help guide my actions.
As a bonus, CO2 levels also correlate with alertness and productivity. When CO2 levels drift into the yellow range (>1000 ppm), cognit...

6 Potential Medical Use Cases for ChatGPT
The internet is buzzing with news on ChatGPT, and how everyone uses it to write love poems, homework, summaries of articles, or python codes. ChatGPT is the latest generation of a large language model, designed to generate text upon user input. There is a lot of discussion regarding its potential use in medicine, so let’s see, what you can expect from it and what you should not use it for – at least in its current form.
Unlike the text-to-image tool Midjourney, which we introduced earlier, and which is a GAN (generative adversarial network, explained here) algorithm, ChatGPT is a different kind of algorithm R...

Save The Nation!
The word " nation, " like many words, has multiple meanings. This inspires some people to make what they think are logical arguments based on insisting that only one selected meaning is valid. I believe I have given the example before of a guy who claimed that the entire concept of organic food is meaningless because " organic " means " carbon compounds " and all food consists of carbon compounds. Always stop and check yourself if you start making an argument based on the definition of a word. We ' ve had the same problem here with " socialism. " Somebody finds one or another dictionary definition and claims it has to mean...

Kno2 ’ s Unique Perspective on Why TEFCA is Different as They Pursue QHIN Designation
As we approach 2023 it is amazing that interoperability, true broad-based connectivity between healthcare systems, looks like the Verizon heatmap back in 2005 when there was as much white on the map as there was red. Much like AT&T, Verizon, and T-Mobile worked diligently to provide coverage to everyone in the U.S., TEFCA (Trusted Exchange Framework and Common Agreement) is driving the QHIN “network” to accomplish the same outcome. Depending on where you sit in healthcare today it may feel like 1986 or 2023. The breadth of connectivity, the exchange of data, and the benefit of both feels significantly differe...

Where Does Diabetes Technology Stand In 2022?
Diabetes management went through a radical transformation in the last years due to technology: the diabetes patient community found a strong voice online, continuous glucose monitors are taking the place of finger pricks, digital patches and insulin pumps make the dosage of insulin more predictable, and connected devices promise the era of artificial pancreas real soon. We looked around where diabetes technology stands today and what could we expect in the next 5-10 years.
