Psychologie : comment mesurer le bonheur ?

1 month ago | nationalgeographic.fr | Nora Bradford |Brian Fink

À la question « Qu’est-ce qui rend la vie belle ? » on répond souvent par une liste de ce qui nous rend heureux. Mais tout le monde ne mesure pas sa vie par le bonheur, et certains y accordent plus d’importance que d’autres. Les humains ont du mal à trouver une recette pour une belle vie ou pour le bien-être qui dépasse le simple fait d'« être heureux ».

chemical: A substance formed from two or more atoms that unite (bond) in a fixed proportion and structure. For example, water is a chemical made when two hydrogen atoms bond to one oxygen atom. Its chemical formula is H2O. Chemical also can be an adjective to describe properties of materials that are the result of various reactions between different compounds. millisecond: A thousandth of a second.
A squid-inspired medical device could reduce the need for needles

If you’re one of the many adults who hate needles, you may be in luck. Scientists have taken inspiration from squids’ high pressure liquid jets and developed a needle-free device to inject drugs into organs deep within the body. “Needles require specialized training to administer, present challenges with safe disposal and carry the risk of needle-stick injuries, whether used externally or for deeper, internal applications,” says Giovanni Traverso, a translational engineering researcher at MIT.
Your brain can perceive subtle odor changes in a single sniff

Oct 14, 2024 | sciencenews.org | Nora Bradford

Human sniffs last between one and three seconds. During that time, chemicals enter the nose and allow us to perceive the smells around us. But whether humans can perceive odor changes shorter than the length of one sniff has been an open question. A new device that allows for precise odor control shows that people perceive much more detail within a single sniff than previously thought. They can perceive odor changes in fractions of a second, researchers report October 14 in Nature Human Behaviour.
Aligning consciousness science and U.S. funding agency priorities - Communications Biology

Oct 12, 2024 | nature.com | Nora Bradford

We recently completed the Fund Consciousness Science! Project: a workshop and subawards program aimed to align United States federal funding mechanisms and consciousness research. Here we describe the project’s motivation, execution, and outcomes to motivate similar efforts both locally and globally. Consciousness science seeks to reveal and explain the neural and computational processes that give rise to consciousness (phenomenological experience).
A brain network linked to attention is larger in people with depression

Sep 25, 2024 | sciencenews.org | Nora Bradford |Laura Sanders

Science News is collecting reader questions about how to navigate our planet's changing climate. What do you want to know about extreme heat and how it can lead to extreme weather events? Lynch and his team hoped to uncover the driving forces behind mood changes in depression by mapping brain networks over time. Existing functional MRI datasets allowed the team to look at the activity, across multiple days, of more than a hundred people’s brains, including those with and without depression.
Pregnancy transforms the brain-and some changes last forever

Sep 20, 2024 | nationalgeographic.com | Nora Bradford

Sex hormones, like estrogen and testosterone, are powerful players in the brain, affecting mood, memory, and more. Some of the most dramatic hormonal changes that humans experience happen during pregnancy, and yet those nine months have been a black box for human neuroscience until now. A new study published this week in Nature Neuroscience provides the most extensive glimpse inside that black box yet.
Probiotics to alleviate depression

Jul 11, 2024 | drugdiscoverynews.com | Nora Bradford

Depression is more common than many might think; it affects 4.4 percent of the US population and 3.8 percent of the global population (1, 2). It also disproportionately affects women, who experience it about 50 percent more frequently than men (2). Despite its prevalence, effective treatment remains elusive for many. Current antidepressant treatments come with a plethora of unwanted side effects, from nausea to insomnia.

calcium: A chemical element and alkali metal common in minerals of the Earth’s crust and in sea salt. It is also found in bone mineral and teeth, and can play a role in the movement of certain substances into and out of cells. cell: (in biology) The smallest structural and functional unit of an organism. Typically too small to see with the unaided eye, it consists of a watery fluid surrounded by a membrane or wall.
