Justin Thomas considers bidets to be “a key green technology” because they eliminate the use of toilet paper. According to his analysis, Americans use 36.5 billion rolls of toilet paper every year, representing the pulping of some 15 million trees. Says Thomas: “This also involves 473,587,500,000 gallons of water to produce the paper and 253,000 tons of chlorine for bleaching.” He adds that manufacturing requires about 17.3 terawatts of electricity annually and that significant amounts of energy and materials are used in packaging and in transportation to retail outlets.

That’s a lot of water, far more than is actually used by the bidet itself.

I know some have speculated that the Coronavirus was engineered:

An analysis of public genome sequence data from SARS-CoV-2 and related viruses found no evidence that the virus was made in a laboratory or otherwise engineered.

The novel SARS-CoV-2 coronavirus that emerged in the city of Wuhan, China, last year and has since caused a large scale COVID-19 epidemic and spread to more than 70 other countries is the product of natural evolution, according to findings published today in the journal Nature Medicine.

Hmm… are people with reduced lung capacity after recovering from the coronavirus more susceptible to getting the flu? Or does taking antibiotics increase one’s risk getting the coronavirus since it attacks the respiratory system?

Antibiotics can leave the lung vulnerable to flu viruses, leading to significantly worse infections and symptoms, finds a new study in mice led by the Francis Crick Institute.

The research, published in Cell Reports, discovered that signals from gut bacteria help to maintain a first line of defence in the lining of the lung. When mice with healthy gut bacteria were infected with the flu, around 80% of them survived. However, only a third survived if they were given antibiotics before being infected.

“We found that antibiotics can wipe out early flu resistance, adding further evidence that they should not be taken or prescribed lightly,” explains Dr Andreas Wack, who led the research at the Francis Crick Institute. “Inappropriate use not only promotes antibiotic resistance and kills helpful gut bacteria, but may also leave us more vulnerable to viruses. This could be relevant not only in humans but also livestock animals, as many farms around the world use antibiotics prophylactically. Further research in these environments is urgently needed to see whether this makes them more susceptible to viral infections.”

Sam Harris discusses the coronavirus withAmesh Adalja.

In this episode of the podcast, Sam Harris speaks with Amesh Adalja about the spreading coronavirus pandemic. They discuss the contagiousness of the virus and the severity of the resultant illness, the mortality rate and risk factors, vectors of transmission, how long coronavirus can live on surfaces, the importance of social distancing, possible anti-viral treatments, the timeline for a vaccine, the importance of pandemic preparedness, and other topics.

Stanford researchers have developed a technique that reprograms cells to use synthetic materials, provided by the scientists, to build artificial structures able to carry out functions inside the body.

“We turned cells into chemical engineers of a sort, that use materials we provide to construct functional polymers that change their behaviors in specific ways,” said Karl Deisseroth, professor of bioengineering and of psychiatry and behavioral sciences, who co-led the work.

In the March 20 edition of Science, the researchers explain how they developed genetically targeted chemical assembly, or GTCA, and used the new method to build artificial structures on mammalian brain cells and on neurons in the tiny worm called C. elegans. The structures were made using two different biocompatible materials, each with a different electronic property. One material was an insulator, the other a conductor.

Politicians won’t admit it yet, but it’s time to prepare—physically and psychologically—for a sudden stop to all life outside your home.

Francisco Garcia, a youth team coach at Malaga-based club Atletico Portada Alta, had an unknown pre-existing health condition that resulted in him being more vulnerable to the virus than usual for an individual of his age, though he was only informed of having cancer after going to hospital with symptoms of coronavirus.

Donating blood is one of the most effective ways Americans can help during the coronavirus crisis, the United States Surgeon General said.

Speaking during a White House coronavirus task force briefing Thursday, Surgeon General Jerome Adams urged healthy individuals, especially millennials and Gen Z, to visit their local blood centers.

“Donated blood is an essential part of caring for patients, and one donation can save up to three lives,” Adams said.

A study by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, offers new insight into genetic alterations associated with osteosarcoma, the most common cancerous bone tumor of children and adolescents. The researchers found that more people with osteosarcoma carry harmful, or likely harmful, variants in known cancer-susceptibility genes than people without osteosarcoma. This finding has implications for genetic testing of children with osteosarcoma, as well as their families.

The study was published March 19, 2020, in JAMA Oncology.

“With this study, we wanted to find out how many people with osteosarcoma may have been at high risk for it because of their genetics,” said Lisa Mirabello, Ph.D., of NCI’s Division of Cancer Epidemiology and Genetics (DCEG), who led the research. “We not only learned that at least a quarter of the people in the study with osteosarcoma had a variant in a gene known to predispose someone to cancer, we also uncovered variants that had never before been associated with this cancer.”
