One day, people could monitor their own health conditions by simply picking up a pencil and drawing a bioelectronic device on their skin. In a new study, University of Missouri engineers demonstrated that the simple combination of pencils and paper could be used to create devices that might be used to monitor personal health.

Their findings are published in the journal Proceedings of the National Academy of Sciences.

Zheng Yan, an assistant professor in the College of Engineering, said many existing commercial on-skin biomedical devices often contain two major components—a biomedical tracking component and a surrounding flexible material, such as plastic, to provide a supportive structure for the component to maintain an on-skin connection with a person’s body.

As cells develop, changes in how our genes interact determines their fate. Differences in these genetic interactions can make our cells robust to infection from viruses or make it possible for our immune cells to kill cancerous ones.

Understanding how these gene associations work across the development of human tissue and organs is important for the creation of medical treatments for complex diseases as broad as cancer, developmental disorders, or heart disease.

A new technology called single-cell RNA-sequencing has made it possible to study the behavior of genes in human and mammal cells at an unprecedented resolution and promises to accelerate scientific and medical discoveries.

I think so.

Will augs like in the video game Deus Ex ever be possible? Why or why not? If one day they are, what are the implications? We have a long way to go, and the more we try to control our system, the less we will have available to us in the future.

The findings support many vaccine strategies being used to tackle the new coronavirus.

A team led by scientists at Scripps Research has discovered a common molecular feature found in many of the human antibodies that neutralize SARS-CoV-2, the coronavirus that causes COVID-19.

The scientists, whose study appears today (July 13, 2020) in Science, reviewed data on nearly 300 anti-SARS-CoV-2 antibodies that their labs and others have found in convalescent COVID-19 patients over the past few months. They noted that a subset of these antibodies is particularly powerful at neutralizing the virus — and these potent antibodies are all encoded, in part, by the same antibody gene, IGHV3-53.

These non-random epigenetic changes imply that evolution has a “mind.” Creatures appear to have complex mechanisms to make epigenetic changes that allow them to adapt to future environmental challenges. But where did this forward-thinking design come from? Evolution is mindless; it cannot see the future. So how could it evolve mechanisms to prepare for the future?

But God does! God is omniscient (all-knowing), and He foreknew Adam and Eve would sin. He would judge that sin (Gen. 3) and the world would be cursed (Rom. 8:22). God knew that organisms would need the ability to adapt in a world that was no longer “very good.” God likely designed organisms with epigenetic mechanisms to allow them to change easily and quickly in relation to their environment. These types of changes are much more valuable than random mutation and natural selection because they can produce immediate benefits for offspring without harming the basic information in the actual sequence of DNA.

Although we often hear that “nothing in biology makes sense except in the light of evolution,” it should be said that “nothing in biology makes sense without the Creator God.” Epi genetics is an exciting field of science that displays the intelligence and providence of God to help organisms adapt and survive in a fallen world.

The Chief Executive Officer of SpaceX and Tesla, Elon Musk, founded Neuralink, a company that is developing a brain-machine interface that could one day restore a variety of brain-related issues, including restoring eyesight and limb functionality, solve memory loss, even cure depression via a brain chip implant. Musk initially aims to focus on the medical aspect of the neural interface, like solving mobility issues with paralyzed individuals. Ultimately, his team aims to achieve ‘symbiosis’ with Artificial Intelligence (AI).

The type of UV light that can kill the new coronavirus is dangerous to use unless you’re properly trained for it.

In mammals, such as humans, DNA contains genetic instructions that are transcribed—or copied—into RNA. While DNA remains in the cell’s nucleus, RNA carries the copies of genetic information to the rest of the cell by way of various combinations of amino acids, which it delivers to ribosomes. The ribosomes link the amino acids together to form proteins that then carry out functions within the human body.

The viral RNA is sneaky: its features cause the protein synthesis machinery of our cells to mistake it for RNA produced by our own DNA.

COVID-19 enters the body through the nose, mouth, or eyes and attaches to our cells. Once the virus is inside our cells, it releases its RNA. Our hijacked cells serve as virus factories, reading the virus’s RNA and making long viral proteins to compromise the immune system. The virus assembles new copies of itself and spreads to more parts of the body and—by way of saliva, sweat, and other bodily fluids—to other humans.
