I had similar symptoms, and I thought it was a covid infection. I need to get myself tested for ADEM. If your child or family member has a strange rash on the back or legs, take them to the hospital to see if it is ADEM before they have seizures like I did.

The objective of this study was to provide an overview of acute disseminating encephalomyelitis, a potential and serious complication of COVID-19.

Blood investigations and CSF analysis were done in 17 patients. Raised inflammatory markers were most commonly seen in nine (ferritin raised in four, C-reactive protein in five, and D-dimer in five), and lymphopenia was seen in four patients.

CSF analysis was not reported in four patients. The reasons for the same were traumatic tap , raised intracranial pressure (ICP) , pandemic reason , and unknown reason.

A recent study published in Viruses reviewed the characteristics of neuraminidase (NA) with emphasis on the development of NA-based universal influenza vaccines.

Influenza causes significant morbidity and mortality worldwide. The influenza virus harbors two glycoproteins on the surface – hemagglutinin (HA) and NA. Infection-or vaccine-induced immune responses are targeted toward HA. Besides, NA-specific antibodies confer protection and can reduce infection severity.

Existing seasonal influenza vaccines confer narrow immune responses specific to the strain, and their efficacy depends on how well the vaccine strains match those in circulation. Thus, universal influenza vaccines with high breadth and potency are required. In the present study, the authors discussed the characteristics of NA, anti-NA antibodies, and recent progress in developing NA-based vaccines.

An international team of scientists have successfully mapped the magnetic field of our galaxy, the Milky Way, using telescopes that observe the sky in the microwave range. The new research is published in Monthly Notices of the Royal Astronomical Society.

The team used the QUIJOTE (Q-U-I JOint TEnerife) Collaboration, sited at the Teide Observatory on Tenerife in the Canary Islands. This comprises two 2.5 m diameter telescopes, which observe the sky in the microwave part of the electromagnetic spectrum.

Led by the Instituto de Astrofísica de Canarias (IAC), the mapping began in 2012. Almost a decade later, the Collaboration has presented a series of 6 , giving the most accurate description to date of the polarization of the emission of the Milky Way at microwave wavelengths. Polarization is a property of transverse waves such as that specifies the direction of the oscillations of the waves and signifies the presence of a magnetic field.

“Suppose you knew everything there was to know about a water molecule—the chemical formula, the bond angle, etc.,” says Joseph Thywissen, a professor in the Department of Physics and a member of the Centre for Quantum Information & Quantum Control at the University of Toronto.

“You might know everything about the molecule, but still not know there are waves on the ocean, much less how to surf them,” he says. “That’s because when you put a bunch of molecules together, they behave in a way you probably cannot anticipate.”

Thywissen is describing the concept in physics known as emergence: the relationship between the behavior and characteristics of individual particles and large numbers of those particles. He and his collaborators have taken a first step in understanding this transition from “one-to-many” particles by studying not one, not many, but two isolated, interacting particles, in this case potassium atoms.

Electric vehicles, powered by macroscopic electric motors, are increasingly prevalent on our streets and highways. These quiet and eco-friendly machines got their start nearly 200 years ago when physicists took the first tiny steps to bring electric motors into the world.

Now a multidisciplinary team led by Northwestern University has made an electric motor you can’t see with the naked eye: an on the molecular scale.

This early work—a motor that can convert into unidirectional motion at the —has implications for and particularly medicine, where the electric molecular motor could team up with biomolecular motors in the human body.

For the first time, scientists have performed an iconic physics experiment with a positron — the antimatter counterpart of an electron, one of the fundamental particles.

Not only did they get some truly interesting results, but this achievement could become the first step towards potentially revolutionary discoveries.

The experiment — an antimatter version of the famous double-slit setup — was carried out by researchers from Switzerland and Italy in order to lay the groundwork for a novel line of super-sensitive experiments that might help solve a mystery concerning the Universe’s two domains of matter.
