A dog in Hong Kong has tested positive for the COVID-19 virus that’s killed at least 2,859 humans across the world over the last two months, World Health Organization officials said Friday.
Dr. Maria Van Kerkhove, the technical lead of WHO’s emergencies program, said the canine tested “weakly positive,” meaning low levels of the virus were found.
Hong Kong scientists aren’t sure if the dog is actually infected or if it picked up the virus from a contaminated surface, she said.

“At the moment, the YITU “Coronavirus Chest CT Smart Evaluation System” can compress the diagnosis of suspected cases to 2–3 seconds. The company also designed a chatbot doctor that can help the public with self-diagnosis through Q&A and recommend nearby hospitals and appointment booking services.”
An article published in medical journal the Lancelet on February 25 finds that reduced medical resource levels will trigger a spike in the coronavirus death rate in the local population beyond the current estimates. The study shows that death rates are over 3 percent in Wuhan city, 2.9 percent in Hubei province, while only 0.7 percent across the rest of China.
Close to 30,000 medical staff from across China have been dispatched to Hubei province to help overworked local medical professionals in the fight against COVID-19. Fast and accurate diagnosis is critical on the front line, and now an AI-powered diagnostic assessment system is helping Hubei medical teams do just that.
Currently, CT lung scans and nucleic acid tests are the two main diagnostic tools doctors use in confirming COVID-19 infections. CT imaging is crucial for diagnosis verification, and also allows doctors to access lung infection severity.

Summary: Vimentin, a cellular filament, helps neural stem cells to clear damaged and clumped proteins, assisting in neurogenesis.

New research by University of Wisconsin-Madison scientists reveals how a cellular filament helps neural stem cells clear damaged and clumped proteins, an important step in eventually producing new neurons. The work provides a new cellular target for interventions that could boost neuron production when it’s needed most, such as after brain injuries. And because clumping proteins are a hallmark of many neurodegenerative diseases, like Alzheimer’s, the new study could provide insight into how these toxic proteins can be cleared away. Assistant Professor of Neuroscience Darcie Moore led the work with her graduate student Christopher Morrow. Their study is available online in the journal Cell Stem Cell.
In China, drivers became folk heroes — will the same happen in the US?
One kind of bacteria can cause colon tumours, while lacking another kind of microbe may lead to ulcerative colitis, an inflammatory bowel condition.
In focal brain diseases, a patient’s neural network loses key connections, preventing the brain from functioning as it miraculously should. But what if there was a way to restore those connections? An EU funded study is seeking to do just that by getting real biological neurons to synaptically communicate with artificial ones.
Though still in the early stages of study, SYNCH, a team of scientists from the U.K., Switzerland, Germany, and Italy, have created what they describe as a “synaptically connected brain-silicon Neural Closed-loop Hybrid system.” Basically, they’ve taken actual brain cells and artificial brain cells, and got them talking back and forth over the internet.
