(CBS4) – As 2020 comes to an end, some of the first Americans
to contract COVID-19 are still experiencing side effects of the coronavirus.
Those who experience many of the common symptoms, as well as brain fog, are now
being studied as “COVID-19 Long Haulers,” people who continue to experience
issues with the virus even after they should have recovered.
Emily Ringering, who contracted COVID-19 in March, said
many of her symptoms are still lingering nine months later.
“I feel like I have aged 20 years,” Ringering told CBS4’s
Dillon Thomas “I had a couple months there where I felt good. Then stuff
started coming back. In late August, stuff started coming back where I was
having memory issues, bad fatigue, joint pain, I was getting winded.”
Ringering was recently admitted to an urgent care due to
shortness of breath, cough, chest pain and more. Though she has continuously
tested negative for the virus since her initial diagnosis, the impacts continue
to persist.
Researchers at UCDavis Health published research stating upwards of 10% of
those who contract COVID-19 could possibly become a long hauler. One of the
most common issues with long haulers is said to be brain fog, where the patient
has memory and overall cognitive struggles.
Ringering said she recently took a test for her cognitive abilities,
which she failed. She said her father, who is over 70, regularly passes the
test with ease.
“I can’t remember what I walked in a room for. Or, I will be in the
middle of a sentence and I will just lose the words,” Ringering said.
UCDavis Health said there currently is no known cause for the long
haulers’ symptoms. Some believe it could be due to a small amount of active
virus still in a system, while others said it could be caused immune systems
overreacting. Also, there is no known timeline as to how long the issues
may last for the long haulers. Studies are underway.

With events happening
fast in the development of solar power and graphene, I’ve added this section.
Updates as they get reported.
Atom-thin transistor uses half
the voltage of common semiconductors, boosts current density
The two-dimensional
structure could by key for quantum computing, extending Moore's Law

Summary: Researchers report a new, two-dimensional
transistor made of graphene and molybdenum disulfide that needs less voltage
and can handle more current than today's semiconductors.
University at Buffalo
researchers are reporting a new, two-dimensional transistor made of graphene
and the compound molybdenum disulfide that could help usher in a new era of computing.
As described in a paper accepted at the 2020 IEEE International Electron
Devices Meeting, which is taking place virtually next week, the transistor
requires half the voltage of current semiconductors. It also has a current
density greater than similar transistors under development.
This ability to operate with less voltage and handle more current is key
to meet the demand for new power-hungry nanoelectronic devices, including
quantum computers.
"New technologies are needed to extend the performance of
electronic systems in terms of power, speed, and density. This next-generation
transistor can rapidly switch while consuming low amounts of energy," says
the paper's lead author, Huamin Li, Ph.D., assistant professor of electrical
engineering in the UB School of Engineering and Applied Sciences (SEAS).
The transistor is composed of a single layer of graphene and a single
layer of molybdenum disulfide, or MoS2, which is a part of a group of compounds
known as transition metals chalcogenides. The graphene and MoS2 are stacked
together, and the overall thickness of the device is roughly 1 nanometer -- for
comparison, a sheet of paper is about 100,000 nanometers.
While most transistors require 60 millivolts for a decade of change in
current, this new device operates at 29 millivolts.
It's able to do this because the unique physical properties of graphene
keep electrons "cold" as they are injected from the graphene into the
MoS2 channel. This process is called Dirac-source injection. The electrons are
considered "cold" because they require much less voltage input and,
thus, reduced power consumption to operate the transistor.
