Hello everyone ~ The content I push to you today is the latest issue of "NO.11 Lab". What interesting research will we bring this time? Let's take a look!
In this issue you will see:
- Is it true that the couple's illness is real? Cohabitation originally had this effect
- Sugary drinks increase the risk of early colorectal cancer
- Self-replicating robots that kick-start super-evolved
- The more you swipe social software, the more unhappy you may be
Is it true that the couple's illness is real? Cohabitation turns out to have this effect!
Who would have thought that in 2022, I would gradually become fascinated with the vlog of couples or couples' lives shared by some bloggers, similar to chasing dramas, but chasing after finding that couples or couples have some similarities in appearance and behavior, and it is really a bit of a "husband and wife" flavor.
While this may seem like an old saying that doesn't have much scientific implications, a recent study published in the journal Atherosclerosis, "Spousal Similarity of Cardiovascular Risk Factors: A Cross-Sectional Comparison of Dutch and Japanese Data from Two Large Biobank Studies," suggests that the types of diseases and their risk factors for cardiovascular disease are similar in both couples.

The study included 28,265 couples in the Dutch Lifestyles sample bank and 5,391 couples in the ToMMo organization in Japan (mean ages 50.0 and 47.7 years, respectively), and analyzed the similarities between biochemical indicators (such as glycosylated hemoglobin, lipid content at various densities, etc.) and cardiovascular-related diseases (such as hypertension, diabetes, metabolic syndrome).
The results found that both Dutch and Japanese couples were equally likely to develop type 2 diabetes and metabolic diseases, and when wives had the same disease, the risk of high blood pressure increased for the husband, and the husband with metabolic disease was also at higher risk of developing the disease.
In addition, the study also found that Dutch couples showed stronger similarities in anthropometric characteristics (such as weight, BMI, waist circumference, etc.) and lifestyle habits (smoking and drinking) compared with Japanese couples, such as 15.5% and 11.4% smoking rates for both Dutch couples, compared with Japanese couples, while Japanese couples had smoking rates of 20.8% and 4.7%. However, these similarities have little to do with whether both spouses share similar genes.
So what is the potentially plausible explanation for the findings? Researchers believe that conjugal consistency can be explained by the selective mating and cohabitation effects.

Selective marriage refers to people's tendency to choose spouses who are more similar in characteristics, such as identifiable characteristics and behavioral, social, and environmental factors. This leads to similarities between spouses. Think about it, this is similar to our mate selection criteria, we tend to choose the other half with similar views, living habits, and hobbies.
The cohabitation effect may be attributed to environmental factors shared by couples or the "partner interaction effect", in which partners influence each other's behavior. The cohabitation effect is also one of the important factors in the increase in spousal consistency with age.
Therefore, some of the "god synchronization" operations of the husband and wife are not only mentally sharp, but also more likely to be the mutual influence and assimilation of long-term living habits, "the enemy does not move and I do not move", follow the "teammates" to eat, drink and have fun and Ge You's paralysis, life is not too beautiful, no wonder everyone says "happiness and fat" after marriage.
Of course, this study also has limitations, such as not tracking the duration of marriage, the study due to other subjective factors affected by the memory shift, etc., but the results of the study and the cohabitation effect also remind us that "happiness fat" is good, couples supervise each other, healthy life is the best choice for our healthy generation.
Sugary drinks will increase
Risk of early colorectal cancer?
The pleasure of sweets makes us and sweets "go both ways", but the adverse effects of foods and drinks with refined sugar on the human body have been extensively studied, such as fatness, dental caries, acne, greasy and dull yellowing of the skin, affecting image management, and further development may cause insulin resistance, metabolic syndrome and cardiovascular disease.
A recent article published in the journal Gut, "Ingestion of sugary drinks in adulthood and adolescence and risk of early-onset colorectal cancer in women," explored the association between sugary drinks and early-onset colorectal cancer in women.
The study, which measured beverage intake in 95,464 adult women between 1991 and 2015 using effective food frequency questionnaires (FFQs), showed that sugary beverages (SSBs: including soft drinks that are non-alcoholic beverages, fruit drinks, sports drinks, and energy drinks) could produce adverse metabolic outcomes throughout a woman's life.
If you consume an extra serving (about 236.56 ml) of sugary drinks per day as an adult, the risk of obesity increases by 12%, and the risk of type 2 diabetes increases by 18%. The biological mechanism is that sugary drinks affect satiety, increased eating, weight gain, blood sugar rise, and then induce insulin resistance, inflammation, obesity and type 2 diabetes.
Increasing the intake of one sugary drink per day in youth (13 to 18 years of age) increased the risk of early-onset colorectal cancer (EO-CRC) by 32%.
Adult sugary drink intake was positively correlated with early-onset colorectal cancer risk, with women who took ≥ 2 servings of sugary drinks per day more than doubled their risk of early-onset colorectal cancer compared to adult women who took < 1 serving of sugary drinks per week.
Women who consumed an extra 1 serving of sugary drinks per day had a 16 percent increased risk of early-onset colorectal cancer. The underlying mechanism is that excess fructose that exceeds the absorption capacity of the small intestine will reach the colon, and the excess fructose causes dysbiosis and endotoxemia, impairs intestinal barrier function, increases intestinal permeability, and thus promotes the occurrence of colorectal cancer.
Seeing this scares me to quickly sip a sip of milk tea, but in the end, it is still necessary to choose the appropriate sugar intake according to my own situation, and do not have the fluke psychology of "as long as I drink fast enough, the weight will not catch up with me", if the daily intake of sugary drinks is not much, the occasional "milk tea day" is not more happy?
Since entering the industrial society, productivity has become a major factor in promoting social development, and the scientific research that is updated and iterative at all times is to liberate and develop productivity, from the tedious and repetitive assembly line work gradually handed over to the machine to complete, to the takeaway robot dog, the emergence of guided robots, and then to the discovery of robot organisms that can achieve self-replication. Every step has witnessed the development of science and technology.

A recent study published in the journal Science Robotics, "A Cell Platform for Developing Synthetic Living Machines," describes a method for generating in vitro biological robots (called xenobots) from Xenobot cells.
The researchers note that the robot doesn't need scaffolding or microprinting technology, which is produced by its cells from self-organization; nor does it need muscle cells to move autonomously through the cilia on its surface, just like a human leg. In addition, the biological robot can navigate the water environment in different ways, heal on its own after injury, and exhibit predictable group behavior.
This is very different from the traditional artificial materials to build robots, imagine that in the future of mature technology, at least in terms of mass production, the robot is convenient and cheap, but also reduces the pressure of the ecological environment, and completes some microscopic experimental studies according to its characteristics of autonomous movement and recording information.
The development of human society is advancing rapidly, and perhaps in the near future we will all be able to live a super-intelligent life that only appears in science fiction films and television works and become accustomed to it.
Why do I become more and more unhappy when I brush vibrato?
Social media as a non-physical communication medium, after the development and expansion of the business has become one of the choices for people to decompress entertainment, and later affiliated with ByteDance's short video platform - Douyin turned out to be a trend, as soon as it was launched, it led the trend, after all, convenient pages and a variety of interesting videos are too attractive.
Brushing vibrato is cool for a while, and brushing vibrato has always been cool, which is probably the norm for me and everyone here. But a recent study found that facebook, snapchat, and tiktok were associated with depression.
A recent study published in the journal JAMA Netw Open titled "The Relationship Between Social Media Use and Self-Reported Depressive Symptoms in U.S. Adults" used a depression screening scale (PHQ-9) to survey 8,045 people who used social software between May 2020 and May 2021.
Of these, 5,395 rated less than 5, so the researchers conducted a second PHQ-9 survey, covering multiple ethnic groups, with an average age of 55.8 years (15.2%); of which 3546 were female respondents (65.7%).
Statistical methods were analyzed by scholars to show that people who used Snapchat, Facebook and TikTok were significantly associated with an increased risk of depressive symptoms, with a 53%, 42%, and 39% increased risk, respectively.
Further analysis showed that Facebook use by people under the age of 35 was associated with depressive symptoms and not with those over 35, but Snapchat and Tiktok were the opposite of Facebook, with Snapchat and tiktok being associated with depressive symptoms and under 35 years of age.
In this way, the age of the audience on social media is also one of the factors influencing depressive symptoms, and although the study confirmed the correlation between social media and depression, it did not delve into the underlying mechanisms.
Maybe brushing vibrato will make us happy for a short time, but indulging in it will affect the progress of work or study, need to take up other time to remedy, tear down the east wall to make up for the west wall, fall into a vicious circle after the pressure increases sharply, then the risk of depression will rise.
Of course, this is only a small personal guess, and the real solution is to plan the time reasonably, maintain self-discipline, and have a peaceful state of mind, so that "Tarzan collapses in front of us and does not change", and nothing can defeat us.
