With the curve finally flattening in the US, the ramping up of anti-viral and vaccine trials against SARS-CoV-2—the virus that causes Covid-19—and the launch of antibody tests to screen for previous infection, it seems like science is rapidly moving towards the end game. How exactly the Covid-19 pandemic will finally bugger off into history is still anyone’s guess, but virologists and public health experts generally agree that immunity is key—either through widespread safe and effective vaccination, or when enough of our population has recovered from infections and gained herd immunity.

Well. That’s the hand-waving, shruggie emoji, “eh who knows” short answer.

Like most processes in biology, immunity to SARS-CoV-2 is complex and mysterious, with results that could rapidly diverge into many possible futures. It’s partly why estimates of how long Covid-19 sticks around to wreak havoc can vary enormously, from months to years to…well, seasonal and forever, similar to the flu.

In November of 2019—likely, even earlier—a tiny entity measuring just a few hundred billionths of a meter in diameter began to tear apart human society on a global scale. Within a few months, the relentless voyager known as SARS-CoV-2 had made its way to every populated corner of the earth, leaving scientists and health authorities with too many questions and few answers.

Today, researchers are scrambling to understand where and how the novel coronavirus arose, what features account for the puzzling constellation of symptoms it can cause and how the wildfire of transmission may be brought under control. An important part of this quest will involve efforts to properly classify this emergent human pathogen and to understand how it relates to other we may know more about.

In a consensus statement, Arvind Varsani, a molecular virologist with ASU’s Biodesign Center for Fundamental and Applied Microbiomics and a host of international collaborators propose a new classification system, capable of situating coronaviruses like SARS-CoV-2 within the enormous web of viruses across the planet, known as the virosphere.

This is the seventh in a series on the impact of the coronavirus on China’s technology sector.

China’s robotics market is forecast to reach US$103.6 billion by 2023, driven by manufacturing, consumer, retail, health care and resource applications.

Chinese robotics companies have seen a surge in demand since the coronavirus outbreak but some believe robot tech is not mature enough for widespread use.

Existing electronic skin (e-skin) sensing platforms are equipped to monitor physical parameters using power from batteries or near-field communication. For e-skins to be applied in the next generation of robotics and medical devices, they must operate wirelessly and be self-powered. However, despite recent efforts to harvest energy from the human body, self-powered e-skin with the ability to perform biosensing with Bluetooth communication are limited because of the lack of a continuous energy source and limited power efficiency. Here, we report a flexible and fully perspiration-powered integrated electronic skin (PPES) for multiplexed metabolic sensing in situ. The battery-free e-skin contains multimodal sensors and highly efficient lactate biofuel cells that use a unique integration of zero- to three-dimensional nanomaterials to achieve high power intensity and long-term stability. The PPES delivered a record-breaking power density of 3.5 milliwatt·centimeter−2 for biofuel cells in untreated human body fluids (human sweat) and displayed a very stable performance during a 60-hour continuous operation. It selectively monitored key metabolic analytes (e.g., urea, NH4+, glucose, and pH) and the skin temperature during prolonged physical activities and wirelessly transmitted the data to the user interface using Bluetooth. The PPES was also able to monitor muscle contraction and work as a human-machine interface for human-prosthesis walking.

Recent advances in robotics have enabled soft electronic devices at different scales with excellent biocompatibility and mechanical properties; these advances have rendered novel robotic functionalities suitable for various medical applications, such as diagnosis and drug delivery, soft surgery tools, human-machine interaction (HMI), wearable computing, health monitoring, assistive robotics, and prosthesis (1–6). Electronic skin (e-skin) can have similar characteristics to human skin, such as mechanical durability and stretchability and the ability to measure various sensations such as temperature and pressure (7–11). Moreover, e-skin can be augmented with capabilities beyond those of the normal human skin by incorporating advanced bioelectronics materials and devices.

The global coronavirus death toll surpassed 200,000 on Saturday, according to John Hopkins University data.

The grim total was reached a day after presidents and prime ministers agreed to work together to develop new vaccines, tests and treatments at a virtual meeting with both the World Health Organization (WHO) and Bill & Melinda Gates Foundation.

“We will only halt COVID-19 through solidarity,” said Dr. Tedros Adhanom Ghebreyesus, WHO Director-General. “Countries, health partners, manufacturers, and the private sector must act together and ensure that the fruits of science and research can benefit everybody.”

North Korean dictator Kim Jong Un is in a “vegetative state” after he underwent heart surgery earlier this month, a Japanese magazine says.

The weekly Shukan Gendai reported Friday that a Chinese medic sent to North Korea as part of a team to treat Kim believed a delay in a simple procedure left the leader severely ill, Reuters reported.

North Korean media hasn’t mentioned Kim’s health or whereabouts, even though reports by other media have sparked international speculation about his well-being.

Background The COVID-19 pandemic caused by SARS-CoV-2 coronavirus threatens global public health. Currently, neutralizing antibodies (NAbs) versus this virus are expected to correlate with recovery and protection of this disease. However, the characteristics of these antibodies have not been well studied in association with the clinical manifestations in patients. Methods Plasma collected from 175 COVID-19 recovered patients with mild symptoms were screened using a safe and sensitive pseudotyped-lentiviral-vector-based neutralization assay. Spike-binding antibody in plasma were determined by ELISA using RBD, S1, and S2 proteins of SARS-CoV-2. The levels and the time course of SARS-CoV-2-specific NAbs and the spike-binding antibodies were monitored at the same time.

Have a good day group 😅.

On Thursday, Donald Trump raised a few eyebrows as he spoke at the White House daily briefing on the coronavirus. Like us previously He reportedly suggested using UV lights or injecting disinfectants into a person affected by the virus.

Oddly enough, Trump’s suggestion not only sparked a conversation, as many people ignored him, but also prompted RB, the makers of Lysol and Dettol, to release a statement to assure everyone that their products are NOT for internal use, despite Trump’s suggestion.

On Friday, the company released the statement in its official website and said: “As a world leader in health and hygiene products, we must be clear that under no circumstances should our disinfectant products be administered to the human body (by injection, ingestion, or any other route). As with all products, our disinfectant products and hygiene should only be used as intended and in accordance with usage guidelines. Read label and safety information. We have a responsibility to provide consumers with access to accurate and up-to-date information as advised by leading health experts public ”.
