SPEAKING CAN TRANSMIT CORONAVIRUS DUE TO TINY DROPLETS OF SALIVA, NIH STUDY SUGGESTS
arly results of a study from the National Institutes of Health (NIH) suggest that coronavirus can be transmitted through the air from tiny saliva droplets that are expelled when people speak.
Although the research is yet to be published or peer reviewed, the preliminary findings could have major implications in developing strategies for halting the spread of the COVID-19 pandemic, according to a Monday letter from the study's authors.
"Further studies are needed to assess the viral titer [concentrations] present in speech-induced droplets in asymptomatic COVID-19 positive persons, but our results suggest that speaking can indeed be a major mode of SARS-CoV-2 transmission," wrote the researchers.
The study used laser imaging to detect thousands of droplets ejected when a person said the words "stay healthy." Researchers said that although droplets produced during speech are tiny, they can transmit a broad range of respiratory diseases. Speech is also said to produce more droplets than coughing, which may be a more obvious mode of transmission.
"Droplets emitted while speaking are much smaller than those emitted when coughing or sneezing," the researchers wrote. "Nonetheless they are sufficiently large to carry a variety of respiratory pathogens, including the measles virus, influenza virus, and Mycobacterium tuberculosis. Moreover, multiple studies have shown that speaking actually produces significantly more droplets than coughing."
Some may joke about a coronavirus baby boom. Here's why you shouldn't try to conceive in quarantine
As much of the world settles into a new routine of social distancing, couples are likely to have a lot more free time at home to snuggle together.
At first blush, you might think couples with some extra time on their hands would do things that could lead to a stork visiting nine months from now.
Yet with US Treasury Secretary Steve Mnuchin warning of dire scenarios and a possible 20% unemployment rate, couples whose jobs are vulnerable in this economy are likely to think again about kicking off their parenting journeys this spring.
Then there's the possibility of more couples splitting up. One marriage registry official in China said he saw a quarantine-related spike in divorces, showing that more time in closed quarters may be doing some couples more harm than good.
But for couples weathering this storm together, is this a time when many will choose to add to their brood?

COVID-19 pandemic proves the need for ‘social robots,’ ‘robot avatars’ and more, say experts
One of the consequences of people being told to stay home to slow the spread of coronavirus is loneliness. And a collection of 13 robotics experts from around the world have a suggestion for how to solve that: a robot pal.
The innovation is just one of many mentioned in an open letter by the global contingent of robotics experts who suggest that the coronavirus pandemic should serve as a catalyst for the increased use and development of robots.
“Now the impact of COVID-19 may drive further research in robotics to address risks of infectious diseases,” says the statement, published March 25 in Science Robotics magazine.
The statement aims to inspire more funding to develop these varieties of robots, many of which it became clear were needed during the 2015 Ebola crisis.
With hair loss on the rise, Asia's men grapple with what it means to be bald
Despite his father having an "m-shaped" hairline, Alex Han from northeast China never thought he'd experience hair loss in his 20s.
While studies have suggested almost all Caucasian men will eventually face some degree of male pattern baldness -- and around half can expect to lose their hair by middle age -- Asian men, and East Asians in particular, have historically experienced the lowest incidence of hair loss in the world.
A 2010 study from six Chinese cities found that fewer than 3% of men aged 18-29, and just over 13% of those in their 30s, experienced male pattern baldness. Earlier research from South Korea suggested that only 14.1% of the entire male population was affected, while Japanese men were found to develop male pattern baldness approximately a decade later than their European counterparts.
But as Han, now 34, later discovered, genetics isn't everything. Stress, poor diet, lack of sleep and smoking can all contribute to hair loss. And with lifestyles in China changing dramatically in recent decades, so too are the country's hairlines.
Pastor who thinks God can change someone’s sexuality also think God will save him from coronavirus
Andrew Wommack, who refused to condemn Uganda’s “Kill the Gays” bill, supports traumatising conversion therapy and claims he witnessed his son rise from the dead, referenced a section from Exodus and said it proved that God would stop the faithful from becoming sick with COVID-19.
I’ve been studying just in the last couple of days, based on all of this, was Exodus 23:25, and that verse says that you shall serve the Lord your God, and He shall take away all sickness – take all sickness away from the midst of thee,” Wommack said in the YouTube stream.
Anti-LGBT+ televangelist Andrew Wommack thinks God will ‘turn off’ cells and stop him from contracting coronavirus.
He then looked up the words “take away” in Hebrew and said they literally translate to “turn off”.
Wommack then suggested that God will turn off “whatever receptors you have in your body that make you receptive to sickness” for Christians, which will apparently prevent them from being affected by coronavirus.

Madonna Donates $1 Million to Gates Philanthropy Partners’ Coronavirus-Relief Efforts
Madonna has donated $1 million to the Gates Philanthropy Partners’ COVID-19 Therapeutics Accelerator, a rep for the organization confirmed to Variety.
“Her contribution is alongside the commitments by the Gates Foundation, Wellcome, Mastercard, U.K. Government and Chan Zuckerberg Initiative – all partners in the initiative,” the rep said, clarifying that “The money will go through the COVID-19 Response Fund operated by Gates Philanthropy Partners, so not directly to the Gates Foundation.”
In a statement on her website, Madonna — seen above accepting Advocate for Change honor at last year’s GLAAD Awards — wrote:
“I’m joining the Bill & Melinda Gates Foundation effort to find a drug that will prevent or treat COVID-19. We need this to protect our health workers, the most vulnerable, and all of our friends and families.
Fad diets DO work... but only for a year: Health benefits such as weight loss and blood pressure vanish after 12 months, new study suggests
After months of counting calories and saying no to desserts, those on a diet will not want to hear this.
But improving eating habits will only keep weight off for less than a year and improvements in blood pressure will also disappear, according to a study.
Scientists looked at 14 popular food fads, including fashionable Atkins and Paleo diets, which were followed for an average of 26 weeks.
The Atkins diet encourages people to limit their carbohydrate intake while Paleo diets mean eating the foods ancient hunter-gatherers used to.
Will Coronavirus Be Gone by Summer? An Expert Provides Updates on the Pandemic
The United States now has the most cases of the new coronavirus, COVID-19, in the world, and the majority of the country is under strict stay-at-home orders to slow the rate of infection. As Americans approach one month since the start of intense social distancing measures, everyone is wondering the same thing: When will this end?
To get a better understanding of what people can expect from COVID-19, Dr. Robert Norton, a professor of public health at Auburn University and member of several coronavirus task forces, answers questions about the virus.
Will COVID-19 be gone by the summer?
“Realistically, I think it’s going to be going well into the summer in some areas,” Norton says.

Plant Disease Primarily Spreads Via Roadsides
An analysis based on mathematical statistics more precise than those previously carried out uncovered the reason why powdery mildew fungi on Åland are most abundant in roadsides and crossings. Identified as the specific cause was that traffic raises the spores found on roadsides efficiently into the air.
The researchers are interested in disease transmission, as it helps explain the occurrence and biology of diseases. There are plant diseases that spread along riversides, bird migration routes, ocean currents or, for example, air traffic networks, much like human diseases that spread through social networks.
The transmission process determines the abundance and location of occurrence, while the method of transmission determines how the diversity of the disease branches off temporally and spatially, and, in the end, how the disease evolves through natural selection.
CDC considering recommending general public wear face coverings in public
Should we all be wearing masks? That simple question is under review by officials in the U.S. government and has sparked a grass-roots pro-mask movement. But there’s still no consensus on whether widespread use of facial coverings would make a significant difference, and some infectious disease experts worry that masks could lull people into a false sense of security and make them less disciplined about social distancing.
In recent days, more people have taken to covering their faces, although it remains a scattershot strategy driven by personal choice. The government does not recommend it.
That may change. Officials at the Centers for Disease Control and Prevention are considering altering the official guidance to encourage people to take measures to cover their faces amid the coronavirus pandemic, according to a federal official who spoke on the condition of anonymity because it is an ongoing matter of internal discussion and nothing has been finalized.
You Shouldn't Be Wearing Gloves to Go Grocery Shopping
There’s a lot of anxiety about grocery shopping these days, and one very visible manifestation of it is the number of people in the aisles wearing gloves. Rubber gloves, dishwashing gloves, regular winter gloves—“I actually witnessed people earlier this week wearing plastic bags on their hands,” says microbiologist Kelly Reynolds, Ph.D., director of the environment, exposure science and risk assessment center at the University of Arizona.
Does wearing gloves make grocery shopping safer? First of all, grocery shopping, if you observe the current novel coronavirus safety recommendations, isn’t ask risky as some parts of the internet have made it out to be (get point-by-point clarity on that here).
Second, and more importantly, “it could be causing a lot more harm than good,” explains Reynolds. There are a number of issues:
Gloves are like hands when it comes to spreading viruses; maybe even worse.
Are your nails too long? A doctor explains why trimming them and removing chipped polish may help prevent the spread of coronavirus
As the coronavirus pandemic continues to impact communities around the world, experts are advising people on the best ways to go about their personal routines, including staying safe while grocery shopping, cleaning produce from the supermarket, and skin-care best practices for social distancing at home.
One of the most recent suggestions that has gained traction online comes from a Facebook post reportedly relaying advice from an Australian nurse for people to keep their fingernails short to help prevent the spread of the novel coronavirus.
Mystery In Wuhan: Recovered Coronavirus Patients Test Negative ... Then Positive
A spate of mysterious second-time infections is calling into question the accuracy of COVID-19 diagnostic tools even as China prepares to lift quarantine measures to allow residents to leave the epicenter of its outbreak next month. It's also raising concerns of a possible second wave of cases.
From March 18-22, the Chinese city of Wuhan reported no new cases of the virus through domestic transmission — that is, infection passed on from one person to another. The achievement was seen as a turning point in efforts to contain the virus, which has infected more than 80,000 people in China. Wuhan was particularly hard-hit, with more than half of all confirmed cases in the country.
But some Wuhan residents who had tested positive earlier and then recovered from the disease are testing positive for the virus a second time. Based on data from several quarantine facilities in the city, which house patients for further observation after their discharge from hospitals, about 5%-10% of patients pronounced "recovered" have tested positive again.
Some of those who retested positive appear to be asymptomatic carriers — those who carry the virus and are possibly infectious but do not exhibit any of the illness's associated symptoms — suggesting that the outbreak in Wuhan is not close to being over.
The Pandemic Has Led to a Huge, Global Drop in Air Pollution
The coronavirus pandemic is shutting down industrial activity and temporarily slashing air pollution levels around the world, satellite imagery from the European Space Agency shows.
One expert said the sudden shift represented the “largest-scale experiment ever,” in terms of the reduction of industrial emissions.
Readings from ESA’s Sentinel-5P satellite show that over the past six weeks, levels of nitrogen dioxide (NO2) over cities and industrial clusters in Asia and Europe were markedly lower than in the same period last year.
Nitrogen dioxide is produced from car engines, power plants and other industrial processes and is thought to exacerbate respiratory illnesses such as asthma.
Do you wear contact lenses? You should switch to glasses to stop spreading the virus
Focus on this, contact lens wearers of the world: To reduce the spread of the pandemic virus that causes Covid-19, experts suggest it's time to put your contact lenses on the shelf and dazzle the world with your frames.
That's because wearing glasses can help you stop touching your face, according to the American Academy of Ophthalmology, a key way any virus is spread, including the novel coronavirus currently spreading across the world.
Why contact lens?
Contact lens users not only touch their eyes to put in and remove their lens twice or more a day, they also touch their eyes and face much more than people who don't wear contacts, said Dr. Thomas Steinemann, a clinical spokesperson for the American Academy of Ophthalmology.
"You touch your eye and then you touch another part of your body," said Steinemann, an ophthalmologist at MetroHealth Medical Center in Cleveland, Ohio.
