Science has investigated why we bite our nails or leave everything until the last minute: “controlled explosions”

Biting our nails until it hurts, bingeing on junk food after a stressful day either open TikTok just when we have to start workingit is not an irritating habit that we would like to erase from our daily lives.

Science reveals that the weight returns four times faster than with a diet

The era of “miracle” drugs to treat obesity is entering a phase of crude scientific maturity, thanks to the time that has passed since its launch on the market. In this way, despite the years with big headlines pointing to great weight losses with Ozempic, science is now able to provide more answers to the … Read more

Washing chicken “to clean it” sounds hygienic. Science says it’s a bad idea (and very dangerous)

“Chicken should never be washed.” This time, it was Higinio Gómez (one of the most renowned gourmet polleros in Spain) who reopened the debate in an interview in El País. But the issue is recurrent and inexplicably generates very opposing positions: from those convinced that washing chicken is a way to “remove germs or dirt” … Read more

Women consistently sleep worse than men. And science has finally discovered why it is

For years we have been able to have a perception in many homes: the women tend to sleep worse, wake up more and feel more tired than men. This is something that for a long time has been dismissed as a subjective perception, but Science has now wanted to close the debate, pointing out that … Read more

Science has discovered that the original “home” of primates was the cold of the north

The mental image is almost universal: an ape-like ancestor jumping among vines in a hot, humid jungle. For almost a century, paleoanthropology has assumed that primates are children of the tropics, however, an ambitious study published in PNAS by researcher Jorge Avaria-Llautureo and his team has blown up this paradigm, since they have seen that … Read more

The problem with animal experimentation is not a lack of ethics, it is that science still does not have a plan B

Scientific research is very necessary for a society to advance with new treatments to alleviate diseases, for example. But there is a big problem behind it that still lingers and that for many people may be incomprehensible: the use of laboratory animals to test these new advances before doing them in humans. And, as recognized … Read more

We have been failing with New Year’s resolutions for decades. Science says it’s because we don’t know how to “cheat”

January starts with a predictable ritual: paying gym membership, fill the fridge with kale or buy paintbrushes for a new hobby. It is the “clean slate effect” that defines Professor Katy Milkman. Human beings do not perceive time linearly, but rather like chapters of a novel. The New Year is the “Black Friday” of new … Read more

Science suggests that economic stress ages the heart

For decades, cardiovascular medicine has operated under an almost immovable dogma: If you want to protect your heart you have to watch your dietexercise and control blood pressure. However, science has begun to see that there are other social factors that can also be very important, such as the status of personal bank accounts. The … Read more

If the question is why today’s songs are so simple, science has the answer: because we are.

I belong to a generation that screamed singing Queen songsLast in line or Extrememoduro that they sounded on a cassette. Therefore, it has not gone unnoticed by me that, in the last five decades, music has changed. The letters they have become simplermore repetitive and loaded with negative emotions or stress. This shows it a … Read more

2,000 years ago, Seneca said that “it is not that we have little time to live, but that we keep wasting it.” Science agrees

20 centuries ago, a man from Cordoba who had been quaestor, praetor, senator and consul of Rome and tutor to Emperors sat down to write a small treatise on the brevity of life. That was where he wrote that “it is not that we have little time to live, but that we waste a lot.” … Read more
