Access to clean water is essentially for good health, yet many around the world lack access to save, clean, drinkable water. Researchers have found a way to clean water more efficiently than previous systems by essentially cleaning water at the source using a new catalyst. The catalyst cleans the water by creating hydrogen peroxide where it needs to be used by running electricity through special metals. This good because it requires less energy and resources to clean large amounts of water.
The catalyst-based method was shown to be 10,000,000 times more potent at killing the bacteria than an equivalent amount of the industrial hydrogen peroxide, and over 100,000,000 times more effective than chlorination, under equivalent conditions.
In addition to this, the catalyst-based method was shown to be more effective at killing the bacteria and viruses in a shorter space of time compared to the other two compounds.
“We now have proven one-step process where, besides the catalyst, inputs of contaminated water and electricity are the only requirements to attain disinfection.
Zoonotic diseases are nothing new and are often the cause of large outbreaks which cause great harm to humans and other animals. It’s speculated that the recent COVID-19 coronavirus popped into existence due to close animal – human contact in Chinese wet markets. History as shown us that wherever there is frequent, close contact between animals and humans there is an increase in the likelihood of new diseases. This has led to scientists calling for reduced meat conniption with the thinking that if eat less meat than the potential for human-animal transmission is reduced in markets and processing facilities.
It is clear that the origins of these pandemics are not restricted to certain countries or certain practices, such as “wet-markets.” For some researchers, including Swedish chief physician and infectious diseases professor Björn Olsen, stemming rising demand for meat and dairy is a necessary part of reducing our risk for pandemics.
Getting enough sleep but still feeling tired? Try taking a rest.
Physician Saundra Dalton-Smith MD has identified seven types of rest everyone needs, and some people need more of a certain kind of rest. What type of rest that helps you depends entirely on your lifestyle and working conditions. The really nice thing about this approach is that sleep isn’t the focus, many people can get the suggested eight hours of sleep and still find themselves exhausted everyday.
The third type of rest we need is sensory rest.Bright lights, computer screens, background noise and multiple conversations — whether they’re in an office or on Zoom calls — can cause our senses to feel overwhelmed. This can be countered by doing something as simple as closing your eyes for a minute in the middle of the day, as well as by intentionally unplugging from electronics at the end of every day. Intentional moments of sensory deprivation can begin to undo the damage inflicted by the over-stimulating world.
Doctors in Canada may soon be prescribing the oldest medicine in the world: walking it off. Thanks to the work of family doctor Dr. Melissa Lem in British Columbia the province will allow a walk in nature to be prescribed by doctors. It’s been proven time and time again that exposure to nature helps with all sorts of medical conditions and recovery times. This initiative to prescribe nature means people can take medical time from work to go for a hike and get a nudge from their doctor to improve their lives.
Dr. Lem wants to bring the program to every province.
Prescriptions for nature became available through this program at the end of last month, and their availability will improve as more health-care practitioners sign up for the prescription packages, which include fact sheets, relevant literature and a unique provider code. This can be done on the program’swebsite.
In the coming months, Lem intends to expand the program to other provinces and territories, forging partnerships between health-care and parks organizations and sharing the resources she has spent years collecting. Until then, she said health-care providers outside B.C. can sign up in advance and will get their prescription packages when the program reaches them.
Iceland’s size helped it grabble the COVID-19 pandemic in a way that other nations couldn’t. The country was able to test half its population and keep a close eye on how the virus spread due to really good contact tracing. Like other countries which have successfully dealt with the pandemic, a robust response proved to be the solution. Iceland even went a step further and has collected their data not only for current protection and safety but also to make it easier for researchers to look back on 2020 to understand how the virus spread.
If the test is negative, the person receives an all-clear text. If the test is positive, it triggers two chains of action: one at the hospital and one at the lab.
At the hospital, the individual is registered in a centralized database and enrolled in a tele-health monitoring service at a COVID outpatient clinic for a 14-day isolation period. They will receive frequent phone calls from a nurse or physician who documents their medical and social history, and runs through a standardized checklist of 19 symptoms. All the data are logged in a national electronic medical record system. A team of clinician-scientists at the hospital created the collection system in mid-March with science in mind. “We decided to document clinical findings in a structured way that would be useful for research purposes,” says Palsson.
In the lab, each sample is tested for the amount of virus it contains, which has been used as an indicator for contagiousness and severity of illness. And the full RNA genome of the virus is sequenced to determine the strain of the virus and track its origin.
