Personal or even “intimate” videos, shared and derided by employees: this is the new scandal that agitates Tesla, whose electric cars and their integrated video system are regularly at the center of controversy. No question of the effectiveness of the “autopilot” or the anonymity of passers-by captured by the integrated cameras: at the heart of the matter, videos of vehicle owners themselves and their environment – enough to relaunch the question of the confidentiality of the data collected by the car manufacturer.
Humans have much less control over their body weight than they think, according to a study by a research team from Laval University and the IUCPQ Research Center, which reveals that the brain plays an important role in relation to the figure indicated on the scale.

Strict diets, diets, physical exercise and the good will of those who wish to lose weight might be of very little use, according to the study led by Benoît Arsenault, professor at the Faculty of Medicine of Laval University and researcher at the IUCPQ.
This study demonstrated that genetic regions associated with body mass index (BMI) influenced the concentrations of several proteins expressed in the brain and that genetic factors might explain up to 50-75% of the variance in BMI. in the population.

It was already known that several hundred genetic regions that influenced body weight, but their functions still remain unknown to this day.
The team therefore focused on a region that notably influences sensitivity to the feeling of reward associated with food intake. This region of the brain, called the dorsolateral prefrontal cortex, would also influence the regulation of appetite and satiety.
“It was not known which proteins had a role to play in the differences in weight from one person to another. So we, with genetic analysis techniques, were able to identify around sixty of these proteins,” explains Mr. Arsenault.

Laziness, a myth
The discovery establishes that the identified genes encode proteins that would influence body weight via their expression in the brain.
With these results, the study shatters the myth of the person who is overweight due to lack of willpower and laziness. The researcher points out that most people living with overweight who have tried dieting have not had the expected results and that “it’s the brain that’s the boss”.
“We think our study may partly explain why these diets don’t work. […] there are neurobiological mechanisms that will prevent this weight loss, ”says Mr. Arsenault.
Next, the researcher will seek to establish the exact function of these proteins and on which biological systems they exert an influence.
“Because weight is not just food intake, but also energy expenditure in a day, sleep – which plays an important role in weight – and stress management,” he adds.
Health experts are sounding the alarm: France is increasingly vulnerable to epidemics of tropical diseases transmitted by the tiger mosquito. Climate change and increasing urbanization create an ideal environment for the reproduction of this vector of dangerous diseases such as dengue, zika and chikungunya.
While the tiger mosquito was once confined to the south of France, it has now spread throughout the country, from the Alps to the Channel coasts. Experts estimate that up to 20 million people might be exposed to this mosquito, which can transmit several deadly diseases.
Unfortunately, preventive measures are often overlooked. Citizens are not sufficiently aware of the risks associated with the presence of the tiger mosquito, and the health authorities are not taking the necessary measures to stop its spread. The government has not allocated enough resources to control the mosquito population, which breeds quickly and spreads easily.
In addition, the insecticides used to control tiger mosquitoes have negative effects on the environment and human health. They can kill beneficial insects and contaminate water and soil. Local people have also reported adverse side effects, such as headaches and rashes.
If France does not take concrete measures to combat the spread of the tiger mosquito, it risks facing a large-scale epidemic in the near future. Authorities must take immediate action to raise awareness of the potential dangers, invest in more effective means of prevention, and investigate alternative and environmentally friendly methods to control the mosquito population. Otherwise, France might face a major public health crisis that might put millions of lives at risk.
The appearance of the model Oriana Sabatini has been a trend in recent days on Twitter. The 26-year-old actress has had a couple of drastic changes to her face, starting with her decision to bleach her eyebrows, which, combined with her makeup, gives her the appearance of no eyebrows.

He also has a large piercing that goes through the bridge of his nose. Her haircut has also been criticized: the Argentinian wears some bangs short and black hair.
Users on Twitter launched into criticism of his appearance, with some even speculating regarding possible plastic surgeries on Sabatini’s face in responses to a viral tweet by user @enz4censur4. “What happens to them that they touch their faces so much? So much self-love and blah blah,” wrote one user.
“Oriana… I don’t understand the need to change the image like this,” said another Internet user. “Poor Oriana. She wants to impose one with the sparkles and it doesn’t come out. He wants to make a musical career and it doesn’t work out either. I should have followed her acting career, maybe it was better for her, ”sentenced another follower.
However, not all the comments regarding Sabatini were negative. Some responses denoted that the screenshot that she uploaded @ enz4censur4 was taken while the artist was speaking, which did not favor her.
“Guys, I make that face and I look like an ape. What a beautiful woman!”, indicated a user. “Guys, Ori is a beautiful woman. Perhaps for you that makeup does not favor her, but she was always super cute, “commented another.

Sabatini has participated in various series and plays. In addition to her modeling career, she has also dabbled in the world of music: she has ten songs released as singles. She is the girlfriend of the Argentine soccer player Paulo Dybala, forward of AS Roma, since 2018. (E)
