Ms. Loyce Pace, MPH, is Assistant Secretary for Global Affairs (OGA), at the U.S. Department of Health and Human Services (https://www.hhs.gov/about/leadership/loyce-pace.html).

In her current role, Ms. Pace is responsible for advancing the U.S. international health agenda through multilateral and bilateral forums. Reporting directly to the Secretary of Health & Human Services (HHS), she is the Office of Global Affairs’ lead on setting priorities and policies that promote American public health agencies and interests worldwide.

To create is human. For the past 300,000 years we’ve been unique in our ability to make art, cuisine, manifestos, societies: to envision and craft something new where there was nothing before.

Now we have company. While you’re reading this sentence, artificial intelligence (AI) programs are painting cosmic portraits, responding to emails, preparing tax returns, and recording metal songs. They’re writing pitch decks, debugging code, sketching architectural blueprints, and providing health advice.

Artificial intelligence has already had a pervasive impact on our lives. AIs are used to price medicine and houses, assemble cars, determine what ads we see on social media. But generative AI, a category of system that can be prompted to create wholly novel content, is much newer.

This video describes the Immune System and explains how it detects and attacks any foreign organism that enters the body.

We learn how the team in the MRC Centre for Transplantation at King’s College London have developed a way to harness the power of the Immune System after a transplant, whilst maintaining the body’s capacity to resist infectious diseases.

Farmed catfish are susceptible to disease, and using antibiotics causes resistance. So researchers turned to CRISPR and alligators.

In a recent study published in the journal Immunity, researchers reviewed the T cell response in cancer and autoimmunity to propose strategies for more effective immunotherapies.

“It doesn’t have just a static function. It has a bank of sensors that measure chemicals in the blood and feeds that information back to the device,” Kurtz says.

Other startups are getting in on the game. Nephria Bio, a spinout from the South Korean-based EOFlow, is working to develop a wearable dialysis device, akin to an insulin pump, that uses miniature cartridges with nanomaterial filters to clean blood (Harhay is a scientific advisor to Nephria). Ian Welsford, Nephria’s co-founder and CTO, says that the device’s design means that it can also be used to treat acute kidney injuries in resource-limited settings. These potentials have garnered interest and investment in artificial kidneys from the U.S. Department of Defense.

For his part, Burton is most interested in an implantable device, as that would give him the most freedom. Even having a regular outpatient procedure to change batteries or filters would be a minor inconvenience to him.

A single drop of blood from a finger prick. A simple electronic chip. And a smartphone readout of test results that could diagnose a Covid-19 infections or others like HIV or Lyme disease.

It sounds a bit like science fiction, like the beginnings of the medical tricorder used by doctors on Star Trek. Yet researchers at Georgia Tech and Emory University have taken the first step to showing it can be done, and they’ve published their results in the journal Small.

Postdoctoral fellow Neda Rafat and Assistant Professor Aniruddh Sarkar created a small chip that harnesses the fundamental chemistry of the gold-standard lab method but uses electrical conductivity instead of optics to detect antibodies and indicate infection.

National Institutes of Health researchers have developed and released an innovative software tool to assemble truly complete (i.e., gapless) genome sequences from a variety of species.

This software, called Verkko, which means “network” in Finnish, makes the process of assembling complete genome sequences more affordable and accessible. A description of the new software was published today in Nature Biotechnology.

Verkko grew from assembling the first gapless human genome sequence, which was finished last year by the Telomere-to-Telomere (T2T) consortium, a collaborative project funded by the National Human Genome Research Institute (NHGRI), part of NIH.

It acted with rudimentary intelligence, learning, evolving and communicating with itself to grow more powerful.

A new model by a team of researchers led by Penn State and inspired by Crichton’s novel describes how biological or technical systems form complex structures equipped with signal-processing capabilities that allow the systems to respond to stimulus and perform functional tasks without external guidance.

“Basically, these little nanobots become self-organized and self-aware,” said Igor Aronson, Huck Chair Professor of Biomedical Engineering, Chemistry, and Mathematics at Penn State, explaining the plot of Crichton’s book. The novel inspired Aronson to study the emergence of collective motion among interacting, self-propelled agents. The research was recently published in Nature Communications.
