Why aren’t restaurants part of the climate solution? This question inspired chef Anthony Myint to go from opening buzzy pop-ups to pushing for a shift to regenerative farming practices in the food system. He explains how it didn’t go the way he expected at first — and how restaurants are now teaming up with farmers…

To End Extreme Poverty, Give Cash — Not Advice | Rory Stewart | TED
Are traditional philanthropy efforts actually taking money from the poor? Former UK Member of Parliament Rory Stewart breaks down why many global development projects waste money on programs that don’t work. He advocates for a radical reversal rooted in evidence: giving unconditional cash transfers directly to those in need, a method that could unlock the…

This video describes one of many incredible advancements in our ability to fight contagion. We have so many tools to help fix our viral problem.
It’s so frustrating that we’re so damned troglodytic that we reject anything socially unpopular, politically unexploitable or industrially unprofitable.
We have effective drugs!
We have effective technology!
We have effective behaviors!
Why are we so content to wallow in our suffering and bicker over trivial tribal beliefs rather than play an active and effective role in our f*ng survival!?
We have the tools and the means to save and improve our lives if we would just use them without weaponizing, stigmatizing, and politicizing them!

Telling people to stay out of the sun and to use high factor sun creams could be part of the reason so many people have run into trouble; not to mention the cultures that use skin lightening creams and avoid the sun altogether! A little bit of sun without allowing oneself to burn is probably good for us!

We have numerous things to kill the virus on surfaces. It’s inside us that’s the issue, so it seems rather irrelevant if light can kill it given it serves no practical help

Far UVC is safe? Since when??? It can burn your skin to a crisp. Just a few seconds of mild exposure and you can smell it. In fact that’s how you can tell real germicidal UVC light bulbs from fake ones sold on eBay: the real ones produce that familiar burnt skin smell. It is also irritating to the eyes, causing scratchy sensation (like sand in the eyes) for hours to days after exposure. Lastly, it’s ionizing, i.e. it produces ozone. And the damage is not limited to living organisms. It causes the discoloration of all materials (except metals) and brittleness of some plastics.
Is it effective against coronavirus? Sure. Under direct exposure. Any virus lurking in the shadow will do just fine.
In a word, a nice try, but sorry. Another “miracle cure” busted.

Killing the virus in the lab isn’t the same as preventing infection. Killing it on surfaces wouldn’t hurt, but most transmission is from the air. Do we know that it will kill the viruses embedded in a droplet of mucus from a cough or sneeze? Given what you said about tears and the outer layers of our skin blocking it I’m skeptical.
I’m not saying it won’t work. It’s a hypothesis worth further testing.
Calling it a “game changer” at this stage is an outrageous, irresponsible and dangerous overstatement. A great example of the very worst in science reporting.
Of course it’s boring to announce that a group of scientists has had some promising results and that further study is warranted. I understand the temptation to overstate things because it gets the attention of your viewers or your readers. But this kind of bad science reporting ultimately makes the public distrust science. When the promising hypothesis fails to pan out after it’s been overhyped people interpret that as a failure of science and an excuse to ignore scientists.

Fair point about airborne transmission but you don’t catch a virus by breathing in one or two stray virus cells, your immune system isn’t completely useless until it is overwhelmed. If you can continuously sterilize the air (99.99% in 2-3 minutes as stated) while also using masks and distancing (also as stated) then you keep the potential presence of airborne viral particles dramatically lower than it would have been, not 100% sterile, but much better than the absence of any intervention where aerosols can float around in currents for 3 hours.
Lewis Stockett
September 1, 2020 at 5:19 pm
ciretose2 Unless you have citations of peer reviewed journals to back up those claims then they are hypotheses. Sensible hypotheses worthy of further research, but no more. Not conclusions. Not even theories. Not actionable and certainly not “game changers”. Science doesn’t work that way. A lot of things seem plausible. We call those hypotheses. A scientist tests them. They attempt to disprove their own hypothesis. After repeated testing they share the results of their experiments with the scientific community. They write up the results of their experiments along with their data and have it peer reviewed. If it stands up to peer review then it’s published in a journal. Then other scientists review their conclusions, attempt to replicate the results, and design experiments of their own. Other scientists build on the original work. They may perform further experiments to see if the initial work has practical applications. Or they may prove that the whole thing is a dead end. It often is.
The popular image of a lone scientist shouting Eureka in a lab and immediately changing the world is a myth. In reality progress comes in small boring steps made by the scientific community as a whole. Every step along the way is published, reviewed, and scrutinized by scientists all over the world. We don’t start calling things facts until we’ve had several rounds of this kind of thing. That’s why we can actually trust what scientists tell us.

UV lights – we use this to sterilize our OR every weekends or after any “dirty” cases. It really kills viruses and bacteria, just be careful not to stare directly at the light, do not enter the room 30minutes to 1hr after sterilizing with UV, cover the transparent walls/windows/doors or any gaps to prevent the UV light coming in direct contact with you. I love the smell of newly UV light sterilized room – smells so clean, and it’s like fresh sunshine (duh!) lol.

September 1, 2020 at 8:24 am
Thanks for the video. One answer – keeping the virus in the air as low as possible (quote) – well, restricting people out of the room is one way. I’m at 12:00 min. more or less, and that suggestion is both logical, and non-helpful in terms of immediate solutions. I know UV light, very well actually – and the concentration of it probably required is not practical, imho. UV light has been killing germs, and germs on infected material for years… and yes, some virus but not all. However the exposure level, and time duration required is probably not practical – and having said that I admit I am still a newbie, even though I have been around it for maybe two decades. We just don’t have the equipment readily available yet. I would also suggest that we need to be working on the cure, more than avoiding the disease. Both are important, but one solution solves both problems, and that’s the cure. Regardless I love hearing the tech background, which many may not know otherwise. I think it should be used right now to protect first responders, operating rooms, and post-op recovery, etc. UV light is definitely on our side in this battle.

gets asked how uvc light can be used in situations where there is limited power. talks about how uvc light doesnt need more energy than normal light. gets asked how long the distance of the sterilization for uvc light is, talks about how you install 1 bulb in a small room and more bulbs in a large room.gets asked if the uvc light can kill aerosol. answers around the qeustion and talks about how they want the lvl of aerosol to be low. i feel like the question were kinda dodged by him.

I learn english and i know the information about 2 HK student has a creative idea, they saw the germ quickly spread through our hand when we use the handle,that cause disease. So they made UV light bulb, with uv light from light bulb mixed with chemical will killing the germ. “That a good” one student inventor said.
