COVID-19 can affect various organs in the body, such as the brain, lungs, heart, and kidneys. But what happens to these organs after the infection is over? How long does it take for them to heal? A new study has tried to answer these questions by using MRI scans to look at multiple organs of people hospitalized with COVID-19.
The study, published in The Lancet Respiratory Medicine, is one of the most comprehensive post–COVID–19 MRI studies to date. It involved 259 patients who had been hospitalized with COVID-19 in the U.K. and 50 people who had never been… More.

The group at Shanghai Jiao Tong University has demonstrated a DNA computer system using DNA integrated circuits (DICs) that can solve quadratic equations with 30 logic gates.
Published in Nature, the system integrates multiple layers of DNA-based programmable gate arrays (DPGAs). This uses generic single-stranded oligonucleotides as a uniform transmission signal can reliably integrate large-scale DICs with minimal leakage and high fidelity for general-purpose computing.
To control the intrinsically random collision of molecules, the team designed DNA origami registers to provide the directionality for asynchronous execution of cascaded DPGAs. This was used to assemble a DIC that can solve quadratic equations with three layers of cascade DPGAs comprising 30 logic gates with around 500 DNA strands.
To make a gene-editing tool more precise and easier to control, Rice University engineers split it into two pieces that only come back together when a third small molecule is added.
Researchers in the lab of chemical and biomolecular engineer Xue Sherry Gao created a CRISPR-based gene editor designed to target adenine ⎯ one of the four main DNA building blocks ⎯ that remains inactive when disassembled but kicks into gear once the binding molecule is added.
Compared to the intact original, the split editor is more precise and stays active for a narrower window of time, which is important for avoiding off-target edits. Moreover, the activating small molecule used to bind the two pieces of the tool together is already being used as an anticancer and immunosuppressive drug.
I wondered when this would happen. Reminds me of the video game “The Last of Us” and there’s a TV series as well. I’m sure they’ll stop it though.
Silver leaf disease is a curse for a variety of botanicals, from pears to roses to rhododendron. Infecting their leaves and branches, the fungus Chondrostereum purpureum can be fatal for the plant if not quickly treated.
Aside from the risk of losing the occasional rose bush, the fungal disease has never been considered a problem for humans. Until this year.
In what researchers suggest is the first reported case of its kind, a 61-year-old Indian mycologist appears to have contracted a rather serious case of silver leaf disease in his own throat, providing a rare example of a pathogen seemingly making an enormous leap across entire kingdoms in the tree of life.
It could be a new way to treat one of the more common and more frustrating symptoms of Alzheimer’s. A team at Johns Hopkins is leading a study on the drug, and you can get involved.

For the first time, a team from the University of Minnesota Twin Cities has synthesized a thin film of a unique topological semimetal material that has the potential to generate more computing power and memory storage while using significantly less energy. Additionally, the team’s close examination of the material yielded crucial insights into the physics behind its unique properties.
The study was recently published in the journal Nature Communications.
<em>Nature Communications</em> is a peer-reviewed, open-access, multidisciplinary, scientific journal published by Nature Portfolio.

Insights into healing and aging were discovered by National Institutes of Health researchers and their collaborators, who studied how a tiny sea creature regenerates an entire new body from only its mouth. The researchers sequenced RNA from Hydractinia symbiolongicarpus, a small, tube-shaped animal that lives on the shells of hermit crabs. Just as the Hydractinia were beginning to regenerate new bodies, the researchers detected a molecular signature associated with the biological process of aging, also known as senescence. According to the study published in Cell Reports, Hydractinia demonstrates that the fundamental biological processes of healing and aging are intertwined, providing new perspective on how aging evolved.

NIH researchers researchers and collaborators have gained some key insights into the biological inner-workings of regrowing a body, the evolution of aging and a unique method to dispose of aging cells, by studying the genomes of a hermit crab (Hydractinia symbiolongicarpus).
