A review of experimental and natural infections of animals with monkeypox virus between 1958 and 2012

Posted by in categories: biotech/medical, health

MPXV was first discovered during a nonfatal outbreak at an animal facility in Copenhagen, Denmark, in 1958. The facility received a continual supply of Asian monkeys (mostly M. fascicularis) and rhesus macaques (Macaca mulatta), which were used for polio vaccine research. The first outbreak occurred 2 months after the monkeys had been received and the second outbreak occurred 4 months after the initial outbreak. The outbreaks occurred in M. fascicularis that had arrived from Singapore. Upon arrival, monkeys were treated with antibiotics and appeared in satisfactory health.


Monkeypox virus (MPXV) was discovered in 1958 during an outbreak in an animal facility in Copenhagen, Denmark. Since its discovery, MPXV has revealed a propensity to infect and induce disease in a large number of animals within the mammalia class from pan-geographical locations. This finding has impeded the elucidation of the natural host, although the strongest candidates are African squirrels and/or other rodents. Experimentally, MPXV can infect animals via a variety of multiple different inoculation routes; however, the natural route of transmission is unknown and is likely to be somewhat species specific. In this review we have attempted to compile and discuss all published articles that describe experimental or natural infections with MPXV, dating from the initial discovery of the virus through to the year 2012. We further discuss the comparative disease courses and pathologies of the host species.

High-resolution laser resonances of antiprotonic helium in superfluid 4He

😳!


The spectral lines of antiprotonic helium atoms are shown to retain their sub-gigahertz linewidth upon submersion in a bath of superfluid helium, enabling the hyperfine structure to be resolved.

A highly efficient colloidal quantum dot imager that operates at near-infrared wavelengths

Posted by in categories: quantum physics, robotics/AI

Advances in the fields of robotics, autonomous driving and computer vision have increased the need for highly performing sensors that can reliably collect data in different environmental conditions. This includes imagers that can operate at near-infrared wavelengths (i.e., 0.7–1.4 ”m), thus potentially collecting high resolution images in complex or unfavorable atmospheric conditions, such as in the presence of rain, fog and smoke.

Researchers at Huazhong University of Science and Technology (HUST), HiSilicon Optoelectronics Co. Limited, and Optical Valley Laboratory have recently developed a near-infrared colloidal quantum dot (CQD) imager. This highly efficient imager was presented in a paper published in Nature Electronics.

“Our group was founded at Wuhan National Laboratory for Optoelectronics, HUST in 2012 and continuously conducts research on CQD materials and devices with Associate Prof. Jianbing Zhang,” Liang Gao, one of the researchers involved in the study, told TechXplore.

A new, faster way to browse physics-based animations

Posted by in category: computing

Computer-based animators who are tasked with bringing to life imaginary worlds and characters are aided by simulators that can model the many possible ways an object or fluid might move through a physical space. Known as “solvers,” these simulators provide a significant head start on the work of animation. But there’s a catch. As computers have gotten faster, these solvers often create too many options for the animator to effectively sort through looking for just the right one.

“A simulator can return thousands of options. It’s so time consuming to sort through them that these helpful solvers can’t be used to their full potential,” said Purvi Goel, a doctoral candidate in at Stanford, who with her mentor, professor Doug James, has created a new approach to refine the search and narrow results to the most promising options.

VirusTotal Reveals Most Impersonated Software in Malware Attacks

Posted by in category: cybercrime/malcode

Threat actors are increasingly mimicking legitimate applications like Skype, Adobe Reader, and VLC Player as a means to abuse trust relationships and increase the likelihood of a successful social engineering attack.

Other most impersonated legitimate apps by icon include 7-Zip, TeamViewer, CCleaner, Microsoft Edge, Steam, Zoom, and WhatsApp, an analysis from VirusTotal has revealed.

“One of the simplest social engineering tricks we’ve seen involves making a malware sample seem a legitimate program,” VirusTotal said in a Tuesday report. “The icon of these programs is a critical feature used to convince victims that these programs are legitimate.”

Cancer Bills, organized by Nicholas Avery

Posted by in categories: biotech/medical, lifeboat

As most of you know I have cancer called multiple myeloma and have had it for almost a decade now. Unfortunately medical bills are staggering, especially in the US. I am asking to reach a goal of $10,000 to help wipe out if not most of my medical debt and expenses. I have over 1,000 friends on Facebook. If each friend donated $8.00 this would help me not only reach but exceed my goal. Please consider helping:

If anyone needs proof of my diagnosis or medical debt please message me.

I have outlined my journey with cancer several years ago on Lifeboat Foundation’s blog: https://lifeboat.com/blog/2018/09/83169
