Boston University researchers’ testing of lab-made version of Covid virus draws government scrutiny

Posted by in categories: biotech/medical, government, health

Research at Boston University that involved testing a lab-made hybrid version of the SARS-CoV-2 virus is garnering heated headlines alleging the scientists involved could have unleashed a new pathogen.

There is no evidence the work, performed under biosecurity level 3 precautions in BU’s National Emerging Infectious Diseases Laboratories, was conducted improperly or unsafely. In fact, it was approved by an internal biosafety review committee and Boston’s Public Health Commission, the university said Monday night.

But it has become apparent that the research team did not clear the work with the National Institute of Allergy and Infectious Diseases, which was one of the funders of the project. The agency indicated it is going to be looking for some answers as to why it first learned of the work through media reports.

Compact and flexible fiber design ensures efficient focusing and razor-sharp images thanks to 3D printing

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

An interdisciplinary team of researchers from Korea, Australia, Great Britain, and Germany—with participation of Leibniz Institute of Photonic Technology (Leibniz IPHT)—were able for the first time to optimize an optical glass fiber in such a way that light of different wavelengths can be focused extremely precisely. The level of accuracy is achieved by 3D nanoprinting of an optical lens applied to the end of the fiber.

This opens up new possibilities for applications in microscopy and endoscopy as well as in laser therapy and sensor technology. The researchers published their results in the journal Nature Communications.

Lenses at the end faces of optical fibers currently used in endoscopy for medical diagnostics have the disadvantage of chromatic aberration. This imaging error of optics, caused by the fact that light of different wavelengths, i.e., different spectral colors, is shaped and refracted differently, leads to a shift in the focal point and thus to blurring in imaging over a wide range of wavelengths. Achromatic lenses, which can minimize these optical aberrations, provide a remedy.

New technology enables the manufacture of materials that mimic the structure of living blood vessels

Posted by in categories: biotech/medical, materials

An international consortium of researchers led by the University of Sydney, has developed technology to enable the manufacturing of materials that mimic the structure of living blood vessels, with significant implications for the future of surgery.

Preclinical testing found that following transplantation of the manufactured blood vessel into mice, the body accepted the material, with new cells and tissue growing in the right places—in essence transforming it into a “living” blood vessel.

Senior author Professor Anthony Weiss from the Charles Perkins Center said while others have tried to build blood vessels with various degrees of success before, this is the first time scientists have seen the vessels develop with such a high degree of similarity to the complex structure of naturally occurring blood vessels.

What’s behind worrying RSV surge in US children’s hospitals?

Posted by in categories: biotech/medical, business

Children’s hospitals in parts of the U.S. are seeing a surge in a common respiratory illness that can cause severe breathing problems for babies.

RSV cases fell dramatically two years ago as the pandemic shut down schools, day cares and businesses. With restrictions easing in the summer of 2021, doctors saw an alarming increase in what is normally a fall and winter virus.

Now, it’s back again. And doctors are bracing for the possibility that RSV, flu and COVID-19 could combine to stress hospitals.

439-Million-Year-Old Fossil Teeth Overturn Long-Held Views About Evolution

Posted by in categories: biotech/medical, evolution

An international team of scientists has found toothed fish remains that date back 439 million years, which suggests that the ancestors of modern chondrichthyans (sharks and rays) and osteichthyans (ray-and lobe-finned fish) originated far earlier than previously believed.

The findings were recently published in the prestigious journal Nature.

New Technique For Decoding People’s Thoughts Can Now Be Done From a Distance

Posted by in categories: biotech/medical, neuroscience

Scientists can now “decode” people’s thoughts without even touching their heads, The Scientist reported.

Past mind-reading techniques relied on implanting electrodes deep in peoples’ brains. The new method, described in a report posted 29 Sept. to the preprint database bioRxiv, instead relies on a noninvasive brain scanning technique called functional magnetic resonance imaging (fMRI).

FMRI tracks the flow of oxygenated blood through the brain, and because active brain cells need more energy and oxygen, this information provides an indirect measure of brain activity.

Children’s hospitals grapple with a nationwide surge in RSV infections

Posted by in categories: biotech/medical, health

“This year, parents are sending their children to daycare and school for the first time following two years of the pandemic. … Children who haven’t been previously exposed to respiratory viruses are getting sick,” Romano said.

Health officials in King County, Wash., are also alarmed as they brace for more cases once winter hits. Dr. Russell Migita with Seattle Children’s Hospital told King 5 News they are seeing about 20 to 30 positive cases every day, adding that those are “unprecedented” figures.
