Reply to comment by dingo1018 in Australian and UK researchers have developed a proof-of-concept display technology that is 100-times thinner than liquid crystal cells and offers a tenfold greater resolution. by unswsydney
Yeah. It was a big thing in the 80s. If you could piggyback a CMOS manufacturer's process you could bootstrap a product line easily.
Now it's not that big a deal because the fab equipment manufacturers can deal with exotic processes, and leading edge processes are themselves extremely exotic compared to something generically CMOS.
It's like plugging a full-color display or automatic transmission. Kind of sad.

You are in denial of data, asking morality questions to numbers is like asking a brick wall to describe the colour green. Your feelings do not change the numbers, the numbers do not care if you would rather not think about the increased likelihood of men leaving their seriously ill partners.
If you do not agree with the study then disprove it with your own, that is how it is done. Until then I'm afraid any philosophical questions or your own personal beliefs do nothing to change the statistics.

Anytime I see a breakthrough on resolution all I can see in my head about is 2 detectives telling a computer guy to keep enhancing a grainy security camera footage till they see the reflection of the killer in the side mirror of a car parked across the street.

> Our metasurfaces are controlled via electrically driven localised transparent heaters that switch the metasurface optical properties by biased voltages <5 V. By applying an asymmetric driving voltage, we achieve flash heating, leading to 625 μs modulation time. It is worth mentioning that such a modulation time is more than 10-fold faster than the detection limit of the human eye (13 ms). Therefore, despite the operational temperature of ~200 °C, it can still be integrated with CMOS devices.
Huh—so does this mean that it’s impractical for something like phone touchscreens? That seems awfully hot.
Really cool work in any case! :)

I hadn't had any in years and my partner had never had it (directly at least - she got hot boxed plenty, but she didn't or realize it). She was looking for pain relief and self medicating with alcohol isn't a good choice. I explained 'it really only lasts a few hours'.

Haha. I was there in line the day they opened. It was actually pretty fun that morning.

Not just cheapest, but simplest and with quality assurance.

Reply to comment by Zestfullyclean87 in Obesity can cause changes in the brain similar to Alzheimer's by Darth_Kahuna
The why tends to be because the government simply incentives/subsidizes unhealthy, addictive foods, which keep foods that make people fat easily accessible, cheap, widespread, and very addicting. See high fructose corn syrup.
Not to be too simplistic, but the why we are fat is directly tied to modern American capitalism/food manufacturing being in bed with the federal government and keeping us fat and sedated rather than well nourished.
Educate enough people on those truths and maybe we can change the system.

As a former led video wall tech: I am so glad I don’t work in that industry. How tf are you supposed to work with something that small in anything resembling a cost effective manner

Totally, nothing wrong with more education. But like a lot of things, if you want a real push, unfortunately it’s gonna take a lot more than that. We have to look at our culture and understand why we continue to engage in these eating behaviors despite negative consequences. I don’t have much of a solution there

You're giving humans too much credit. Check out the quiverfull cult. Those people alone could grow to 50 billion within 500 years with that tech.

Eh, grew up with a heavy set parent and became an active gym visitor with a steady workout routine. I was definitely influenced by some early educators, so I do think expanding this education will have a positive impact!

For example I do not believe it - it is therefore not a common belief, merely a popular one.
Statistics give an indication of what could be, never reveal what is.
What is the validity of having a study comparing men with women? Does it achieve a goal of enlightening the individual of their own circumstances?
The more you ask questions of it (using the scientific method) the more it falls apart.

Actual paper:
https://content.iospress.com/articles/journal-of-alzheimers-disease/jad220535
Abstract:
>Background:
>
>Excess weight in adulthood leads to health complications such as diabetes, hypertension, or dyslipidemia. Recently, excess weight has also been related to brain atrophy and cognitive decline. Reports show that obesity is linked with Alzheimer’s disease (AD)-related changes, such as cerebrovascular damage or amyloid-β accumulation. However, to date no research has conducted a direct comparison between brain atrophy patterns in AD and obesity.
>
>Objective:
>
>Here, we compared patterns of brain atrophy and amyloid-β/tau protein accumulation in obesity and AD using a sample of over 1,300 individuals from four groups: AD patients, healthy controls, obese otherwise healthy individuals, and lean individuals.
>
>Methods:
>
>We age- and sex-matched all groups to the AD-patients group and created cortical thickness maps of AD and obesity. This was done by comparing AD patients with healthy controls, and obese individuals with lean individuals. We then compared the AD and obesity maps using correlation analyses and permutation-based tests that account for spatial autocorrelation. Similarly, we compared obesity brain maps with amyloid-β and tau protein maps from other studies.
>
>Results:
>
>Obesity maps were highly correlated with AD maps but were not correlated with amyloid-β/tau protein maps. This effect was not accounted for by the presence of obesity in the AD group.
>
>Conclusion:
>
>Our research confirms that obesity-related grey matter atrophy resembles that of AD. Excess weight management could lead to improved health outcomes, slow down cognitive decline in aging, and lower the risk for AD.

We know it’s bad for us, but when the average person is overweight or obese, there comes a point where words mean nothing because of what’s being modeled at home, and around you

I suppose with regards to OP question they would be able to see the difference in a thinner display with lower energy use, totally!

I think it's referring to CMOS manufacturing processes isn't it? As in they don't have to sink billions into new fabrication tech rather it's materials science that current processes could adapt into established knowledge base, so like they didn't reinvent the wheel they just made better wheels?

Reply to comment by gjr23 in Women with satisfying relationships tend to have fewer chronic illnesses by BlitzOrion
Exactly this. As someone who suffers from a chronic illness I can tell you absolutely the only reason I'm not in a relationship is because of my health problems. I would certainly have a much higher chance of being in a satisfying one if I had the physical strength to just be in one in the first place.
