Lab-Made Coronavirus Triggers Debate

Posted by in category: biotech/medical

Circa 2015. The nature publishing has since been pulled down, but I am looking for it. I think I downloaded the pdf.

Infectious-disease researcher at the University of North Carolina at Chapel Hill, last week (November 9) published a study on his team’s efforts to engineer a virus with the surface protein of the SHC014 coronavirus, found in horseshoe bats in China, and the backbone of one that causes human-like severe acute respiratory syndrome (SARS) in mice. The hybrid virus could infect human airway cells and caused disease in mice, according to the team’s results, which were published in Nature Medicine.


Update (March 11, 2020): On social media and news outlets, a theory has circulated that the coronavirus at the root of the COVID-19 outbreak originated in a research lab. Scientists say there is no evidence that the SARS-CoV-2 virus escaped from a lab.

No evidence COVID-19 transmits through food or packaging

Posted by in categories: biotech/medical, food

AMES, Iowa — Over the past month, false information about COVID-19 and food and food packaging has been reported in the media, websites and blogs, and shared through social media, note food safety and nutrition and wellness specialists with Iowa State University Extension and Outreach. Angela Shaw, Anirudh Naig, and Shannon Coleman want Iowans to know there is no evidence that COVID-19 is transmitted through food and food packaging.

Shaw is a food safety state specialist and associate professor in the ISU Department of Food Science and Human Nutrition. Naig is a food safety state specialist and associate professor in the ISU Department of Apparel, Events, and Hospitality Management. Coleman is an assistant professor and nutrition and wellness state specialist in the ISU Department of Food Science and Human Nutrition.

Indian Army has disinfectant drone, UV gun that kills virus in seconds in its Covid arsenal

Posted by in categories: 3D printing, biotech/medical, computing, drones

The cost of the sanitiser would be Rs 800, and the Army can turn out 10 pieces a day.

The third innovation is a 3D-printed mask priced at Rs 1,200 apiece. Other products being devised include thermal scanners and anti-aerosalination boxes to keep doctors safe. The boxes are made up of transparent acrylic sheets and kept over patients to protect doctors and other healthcare workers from infection. Holes cut into the box help medical staff administer treatment to the patient without coming into direct contact.

The Army is just one of several sections across Indian society that are trying to chip in for the country’s battle against coronavirus, from scientists who have banded together to bust myths to IITians churning out cost-effective and innovative solutions to ease the burden on the healthcare framework.

New universal Ebola vaccine may fight all four virus species that infect humans

Posted by in category: biotech/medical

CINCINNATI — Infectious disease scientists report early development of a potential universal vaccine for Ebola viruses that preclinical tests show might neutralize all four species of these deadly viruses infecting people in recent outbreaks, mainly in Africa.

Scientists at Cincinnati Children’s Hospital Medical Center report their preclinical results in the Journal of Virology, published by the American Society for Microbiology.

Although still in early preclinical testing, researchers report that their data indicate that the prospective vaccine has potential to be a stand-alone protection from Ebola. It also could broaden and extend the durability of protective immunity induced by current live vaccines already being tested in clinical trials against individual Ebola virus species, said Karnail Singh, PhD, the study’s co-principal investigator in the Division of Infectious Diseases.

No guarantees of Covid-19 vaccine but prospects very good, scientist says

Posted by in category: biotech/medical

Nobody can be “completely certain” that it is possible to find a vaccine for Covid-19, but the prospects are “very good”, according to a scientist who is leading a team attempting to develop one.

Sarah Gilbert, Professor of Vaccinology at Oxford University, said they hope to begin clinical trials towards the end of next week.

And she said that alongside these trials, preparations need to be made to manufacture the vaccine in large amounts.

Israeli scientist claims he is two-thirds the way to COVID-19 vaccine

Posted by in category: biotech/medical

Even so, a vaccine would still take more than a year to develop, he said.

Gershoni, who has studied the family of viruses for 15 years, said that he was recently granted a patent by the United States Patent and Trademark Office for his vaccine design. He explained that the vaccine intends to target the virus’s Receptor Binding Motif (RBM), a critical weak point which allows the virus to attach itself and infect a target cell.

COVID-19: Teenage Muslim boy from Lucknow “beaten” for buying biscuits, dies

Posted by in categories: biotech/medical, food

A teenaged Muslim boy from Lucknow who was allegedly beaten up by policemen while he was trying to buy food has succumbed.

The slain has been identified as Mohammad Rizwan, he has become the first fatality from purported police high-handedness in enforcing the lockdown in Uttar Pradesh.

Rizwan’s father, Mohammed Israil, said his son had felt very hungry on Thursday night.

Under pressure: New bioinspired material can ‘shapeshift’ to external forces

Posted by in categories: biotech/medical, engineering

Inspired by how human bone and colorful coral reefs adjust mineral deposits in response to their surrounding environments, Johns Hopkins researchers have created a self-adapting material that can change its stiffness in response to the applied force. This advancement can someday open the doors for materials that can self-reinforce to prepare for increased force or stop further damage. A report of the findings was published today in Advanced Materials.

“Imagine a bone implant or a bridge that can self-reinforce where a high force is applied without inspection and maintenance. It will allow safer implants and bridges with minimal complication, cost and downtime,” says Sung Hoon Kang, an assistant professor in the Department of Mechanical Engineering, Hopkins Extreme Materials Institute, and Institute for NanoBioTechnology at The Johns Hopkins University and the study’s senior author.

While other researchers have attempted to create similar synthetic materials before, doing so has been challenging because such materials are difficult and expensive to create, or require active maintenance when they are created and are limited in how much stress they can bear. Having materials with adaptable properties, like those of wood and bone, can provide safer structures, save money and resources, and reduce harmful environmental impact.

Frozen in time: You can be cryogenically preserved, but will you ever be revived?

Posted by in categories: biotech/medical, cryonics, finance, life extension

Why is Alcor in Arizona? The main reason is that the risk of earthquakes and other natural disasters is fairly low. People opting for cryonics expect that their bodies might be in stasis for timescales measured in centuries.

As far as financial matters go, many of Alcor’s clients use life insurance policies to cover the cost of preservation and maintenance ($200,000 for a whole body or $80,000 for just the head). People use trust funds if they have net worth they want to recover when revived in the future.
