Did I miss where they gave the reasoning of the words they chose for the study or was it not specified in the article?

In the same light, it is easy to fool people into thinking who you’re not as well.

How much above chance? Might be only a small improvement over chance.

British Columbia’s school-based human papillomavirus (HPV) immunization program is dramatically reducing rates of cervical pre-cancer in B.C. women, according to a new study

It’s really great that B.C.’s immunization programs are tied to their schools. That’s one of the best and easiest ways to get kids vaccinated. My parents wouldn’t have even bothered to get me a flu shot had my school not offered them, so it’s good to hear that people’s kids are not only going to school to learn, but also to possibly be saved from future cancer/HPV transmissions.

One of the men who worked on this vaccine gave a lecture in one of my courses last year.

Extremely interesting virus

I’m pretty sure every province does this. I remember everyone getting the shot in grade 6 (10 years ago) and I live in the smallest province in Canada.

A widely-used gas that is currently produced from fossil fuels can instead be made by an ‘artificial leaf’ that uses only sunlight, carbon dioxide and water, and which could eventually be used to develop a sustainable liquid fuel alternative to petrol

“A widely-used gas”.

>Syngas is currently made from a mixture of hydrogen and carbon monoxide, and is used to produce a range of commodities, such as fuels, pharmaceuticals, plastics and fertilisers.

There, save you a click.

Edit: woah, thanks for the silver! Totally wasn’t expecting that.

A_Light_Spark

Do they mention anywhere what form the CO2 feedstock is? Does it work with atmospheric concentration of CO2 and water vapour like a real leaf, or does it need concentrated CO2?

ShelfordPrefect

Can those fuel alternatives also be used in the other chemical processes that uses petrol for generating plastic? I am feeling that this could become more crucial for the future as petrol will become less important within the next years – besides airplanes and ships. But I am not sure those alternatives are feasible for the latter?

Bolitho

Hmm. So its a syngas producer that varies from gasification by using energy from photovoltaic sources rather than partial combustion. It’s a unique idea, and the use of Cobalt as a catalyst to help produce it is unique. I’m interested in seeing what the efficiency of the device is currently.

Like the article states, syngas has been around a long time and is basically an intermediate product that has a lot of flexibility in end product development. In gasification, the major hurtles are mainly plant startup and energy intensiveness, as it takes a lot of energy to get the gasification reactor up to the right temperature, and a lot of consumables (i.e. pure oxygen). A definite plus of this leaf vs gasification is hopefully the more safe production of syngas (or hopefully if they can bypass that part altogether) as producing hydrogen gas and CO are extremely volatile.

What ever happened to the “blue algae” research?

Scientists have announced a new gene-editing tool called “prime editing” that avoids some of the pitfalls of CRISPR’s genetic “scissors” approach. The new technique is the first to “search-and-replace” genes without breaking DNA.

Temper your expectations. Packaging a giant molecule like that is going to be very, verrry difficult. This will probably work much better on ex vivo modified cells than curing someone with disease who is already grown. The same group created base editors that generated a lot of buzz when they first came out, yet it took a while before people realized base editors had a shitload of off targets too and even unexpectedly modified RNAs.

Don’t forget, the more exotic you engineer proteins, the more chances you potentially have for making an immunogenic response. Reverse transcriptase is viral derived while Cas is of bacterial origin. We already know Cas is immunogenic. Your body and cells aren’t stupid. Your cells are constantly degrading proteins and presenting the breakdown products on their surfaces to get analyzed by the immune system. Viral + bacterial peptides from the degradation of prime editors could easily get broken down and potentially presented by MHC molecules on the surface, in theory. Your immune system would see it and kill cells that were gene edited, limiting their fitness over the long run. Like i said, for now I can see ex vivo applications of a lot of new Gene editing/crispr ideas, but the massive hurdle of delivery, efficiency, reduction of off targets and avoiding immune system detection is a super difficult problem if we are talking about curing someone rather than ex vivo.

Could this repair a CTG trinucleotide repeat in the DMPK gene?

MrJim911

I’d be concerned about the fact that it is a reverse transcriptase. What have they done about their notorious inaccuracy?

8-year longitudinal study concludes the amount of time spent on social media is not associated with increased anxiety or depression in teenagers. Researchers write “Hopefully these results can move the field of research beyond its past focus on screen time.”

I’d like to know who funded the study

Azozel

I think this is helpful research. Let’s stop talking about time spent and start talking about about what’s actually happening during that time. The active vs. passive social media behaviors that the study’s author outlines are especially helpful to examine.

jMcBee84

Is this saying that social media doesn’t increase anxiety or depression in teenagers, or that it doesn’t increase anxiety or depression in teenagers ANY MORE than it increases anxiety or depression in adults? Because I’ve seen a lot of studies that say social media is essentially bad for the mental space for most people.

i_am_a_toaster

Thought this quote from the release was interesting. “It’s not just the amount of time that is important for most kids. For example, two teenagers could use social media for exactly the same amount of time but may have vastly different outcomes as a result of the way they are using it.” There’s a lot of good content to be found on social media. We could all benefit from thinking about what type of content we’re consuming.

splashbrother12

May be interesting to measure face to face time, as in how often you socialize in person. Could be screen time is irrelevant as long as you also get real socialization

Study finds insufficient evidence of gaming as a clinical disorder. Rather than being negatively impacted by gaming itself, it’s suggested that young people who engage in dysfunctional gaming may be doing so in a bid to escape ““underlying frustrations and wider psychosocial functioning issues”.

I suspect this is true for addiction disorders in general. People don’t just suddenly become addicted to alcohol or drugs, it’s an attempt to escape.

radome9

So… escapism is being used as escapism? Should we read the glass menagerie?

Tobeck

Today on, “Conclusions that are self-evident to anyone without an axe to grind…”

keithrc

As someone who both diagnoses/treats addictive disorders and has issues with excessive gaming, I have a few words about this study.

This study doesn’t find insufficient evidence of gaming as a clinical disorder as a whole, it only identifies that video game use among young people does not cause emotional and behavioral problems.

When we look at a substance use disorder we focus on the degree of effort put forth to acquiring and using the substance, intrusive thoughts of substance use, and how this substance use is impairing functioning.

Young people have almost zero responsibilities. School work for someone who is mildly intelligent can be done well enough with little effort, so excessive gaming doesn’t get in the way of that measure. Most young people don’t have high demand jobs. Take these kids and give them each a 40+ hour a week job, several monthly bills, a partner, 2-3 children, a chronic medical condition and we are going to see some of them fail to meet the obligations of their lives.

PhlegmPhactory

This should’ve been really obvious from the start.
What are they defining as dysfunctional gaming though? I just want to say that simply playing a lot shouldn’t be a part of that. People **enjoy** gaming more than movies/TV or most forms of entertainment in most cases as there’s so much more interaction, immersion, etc., it’s essentially the highest quality form of digital entertainment with infinite variety*(something for everyone)*, so of course they’re going to do it a lot. However, there are definitely people who play a lot as a **result** of their “dysfunctions” which I want to say is actually relatively rare, rather than enjoying it as a hobby or something; just don’t lump it all together. 🤷🏼‍♂️

Case report of a man who appeared drunk and was arrested for drunk driving even though he had never drunk alcohol. He was diagnosed with auto-brewery syndrome, a rare condition where fungal yeast took over his gut microbiome after a course of antibiotics, which fermented carbohydrates to alcohol.

So, untreated he would have been constantly drunk? That can’t be healthy.

mowinski

I’ve deliberately linked to the original source journal article that is open access and full-text.

The title of my post is a copy and paste from the abstract of the linked journal article here:

> Auto-brewery syndrome (ABS), also known as gut fermentation syndrome, is a rarely diagnosed medical condition in which the ingestion of carbohydrates results in endogenous alcohol production. The patient in this case report had fungal yeast forms in the upper small bowel and cecum, which likely fermented carbohydrates to alcohol. Treatment with antifungal agents allowed subsequent ingestion of carbohydrates without symptoms. He had been exposed to a prolonged course of antibiotics before this occurred. We postulate that the antibiotic altered his gut microbiome, allowing fungal growth.

And the Case History:

> One morning, he was arrested for presumed driving while intoxicated (DWI). He refused a breathalyser analysis and was hospitalised. His initial blood alcohol level was 200 mg/dL. The hospital personnel and police refused to believe him when he repeatedly denied alcohol ingestion. He recovered fully and was discharged.

I wonder if this will make it into the court rooms? It could establish reasonable doubt in any DWI case.

Is this here because of last night “The Good Doctor” episode?

Technically he was driving drunk and that’s all the law cares about.

Edit: /u/spanj below me was very kind to give a very good and concise answer regarding the matter! Please read his comment to understand how.

daveboy2000

Come to think of it, if meat can be produced in this way, could skin theoretically also be grown for the purpose of making leather?

AshFalkner

Could cheap Wagyu steaks be on the horizon? Or something that tastes even better/is more nutritious? Any food scientists/meat professionals here to weigh in on this?

DrakuliasAlfonz

What I wonder about this stuff is the kinesthetic aspects of muscle/meat—like movement is a big part of muscle development and changes the structure of the fibers, so how does muscle grown in a stationary mass compare to muscle that has developed on a skeletal frame, and therefore experienced the natural pressures of tension/flexion etc?

Also what about the vascular system? Does a lack of blood/blood vessel effect the nutritional quality of it at all?

inu-hime

My understanding is the problem comes from fat incorporation. While we are able to grow the meat, it still doesn’t taste right because it’s a meat cube.

They could have fixed this by now, but lab grown meat will definitely be a thing in the future.
