The initial cases of novel coronavirus (2019-nCoV)–infected pneumonia (NCIP) occurred in Wuhan, Hubei Province, China, in December 2019 and January 2020. We analyzed data on the first 425 confirmed cases in Wuhan to determine the epidemiologic characteristics of NCIP.


Since December 2019, an increasing number of cases of novel coronavirus (2019-nCoV)–infected pneumonia (NCIP) have been identified in Wuhan, a large city of 11 million people in central China.1–3 On December 29, 2019, the first 4 cases reported, all linked to the Huanan (Southern China) Seafood Wholesale Market, were identified by local hospitals using a surveillance mechanism for “pneumonia of unknown etiology” that was established in the wake of the 2003 severe acute respiratory syndrome (SARS) outbreak with the aim of allowing timely identification of novel pathogens such as 2019-nCoV.4 In recent days, infections have been identified in other Chinese cities and in more than a dozen countries around the world.5 Here, we provide an analysis of data on the first 425 laboratory-confirmed cases in Wuhan to describe the epidemiologic characteristics and transmission dynamics of NCIP.

If you’ve never heard of a tensegrity structure, you should stop now and watch the video below. In it, [The Action Lab] shows a 3D printed table that is held up only with strings. We didn’t say suspended by strings but held up. Or so it appears. The model is from Thingiverse, but it is one of those things you have to see to believe.

The basic idea is pretty simple. Strings have a lot of tensile strength but collapse under the slightest compressive force. The arrangement of strings puts the force on the center string which is essentially hanging — the force is pulling the string down. The other three strings aren’t just for show, though, they keep the structure from tipping over in any one direction.

There are actually real-life examples of these kinds of structures. The video shows the Skylon at the Festival of Britain as one example and an Australian bridge. The video also makes the point that the human body uses tensegrity, since tendons are very similar to the strings in the model.

As countries work to fight the spread of the coronavirus, it has become clear that traditional methods of fighting disease have proven ineffective. Considering the threat, Russia is now pushing for more digital payments so it won’t be spread out on cash. Russia isn’t alone in worrying about people contracting coronavirus from handling cash, as widespread concerns over if you can get coronavirus from currency have caused many leaders to call for less money changing hands.

According to Sky News host Rowan Dean “China willfully inflicted” the coronavirus upon the world a spectacular display of “communism” at its very worst”. “Let’s be absolutely crystal clear, this is an inevitable consequence of communism and totalitarianism,” Mr Dean told Sky News host Peta Credlin. “First of all they tried to shut it up and suppress those individuals who were sounding the alarm” after which they panicked “attributed the blame to the United States which is just laughable,” Mr Dean said. “China must be held to account for this…and countries around the world need to start looking at their relationship with China in light of this disaster”. “If it were a company or if it were an individual… that had caused such worldwide damage other countries would be asking for reparations,” Mr Dean said.

Healthcare professionals and infectious disease experts around the world agree that extensive testing is the best way to combat coronavirus. However, the extreme shortage of COVID-19 testing kits has made that impossible. The Public Health England (PHE) just announced it was planning to begin rolling out at-home COVID-19 testing kits in the coming days. These tests could tell people if they’ve been infected with COVID-19 in as little as 15 minutes.

Current coronavirus testing is time-consuming and expensive because it requires healthcare practitioners to collect samples from the patient and have them processed in a laboratory. The test promised by the UK government would look like a pregnancy test and needs just a drop of blood to diagnose the individual.

Several companies are working on at-home COVID-19 tests, but PHE didn’t say which test it planned to deploy. According to PHE, the unnamed test takes 15 minutes to work, and it will be available at pharmacies and online via retailers like Amazon. The test will detect antibodies in the user’s blood that indicate they have been exposed to the SARS-CoV-2 virus. It works with both Immunoglobulin M and Immunoglobulin G (IgM and IGG) type antibodies. IgM peaks early in an infection and IgG remains even after the infection has subsided.

Heart injury could be a common condition in patients hospitalized with Covid-19, according to a new study that also shows it’s linked to a greater risk of death among those patients.

The study, published in the medical journal JAMA Cardiology on Wednesday, found that among a group of Covid-19 patients hospitalized in Wuhan China, 19.7% suffered cardiac injury, which was found to be a risk factor for dying in the hospital.

Cardiac injury, also referred to as myocardial injury, occurs when there is damage to the heart muscle, and such damage can occur when blood flow to the heart is reduced — which is what causes a heart attack.

Unlocking the full potential of cannabis for agriculture and human health will require a co-ordinated scientific effort to assemble and map the cannabis genome, says a just-published international study led by University of Saskatchewan researchers.

In a major statistical analysis of existing data and studies published in the Annual Review of Plant Biology, the authors conclude there are large gaps in the scientific knowledge of this high-demand, multi-purpose crop.

“Considering the importance of genomics in the development of any crop, this analysis underlines the need for a co-ordinated effort to quantify the genetic and biochemical diversity of this species,” the authors state.

Stanford scientists may have found a way to essentially return older cells to a more youthful state. The adult cells are treated with a mix of proteins from early embryonic development, which removes many of the molecular signs of aging. The cells closely resembled younger ones, and in mouse tests, older animals regained the muscle strength of youth.

Stem cells have the remarkable ability to differentiate into basically any other type of cell in the body. That’s not only important for healthy development of embryos, but it opens an intriguing possible treatment for replenishing lost cells to repair damage to organs and tissues.

Induced pluripotent stem cells (iPS cells) are an emerging method for this kind of treatment. Scientists first take samples of a patient’s adult cells, often from the skin, and then expose them to what are known as Yamanaka proteins. These essentially rewind the cells’ clocks back to an embryonic state, where they’re once again ready to become whatever specialized cells are currently needed.
