All ‘”Eternal Shine” – they try to erase traumatic memories



Presented by:


Happy New Year to all! Welcome to a new edition of Cultívate, El Mostrador’s science and culture newsletter. May this 2023 come true and let’s move forward. Come on, the holidays are coming!

Before starting, I remind you that this is an abridged version of the edition that comes out on Fridays. Now they have a new opportunity to be part of the community cultivate yourself and here we invite you to sign up for free . I promise you we won’t spam. And if you like what I do, please share the newsletter with your friends, colleagues and family. Let’s begin!

1- “ETERNAL GLOW”: SCIENTISTS TRY TO ERASE TRAUMATIC MEMORIES

I’m a big fan of Eternal light of the pure mind, Michel Gondry’s film about a love affair with Kate Winslet and the incombustible Jim Carrey, and how the couple later undergo a memory erasure to forget each other.

  • Well, an article by BBC explore the possibility what can become reality today.

  • Specifically, the stimuli could be used, in this case auditory, to uninstall negative experiences, as confirmed by researchers from the University of York (England) in a recent study.

  • The note also mentions propranolola drug used to treat high blood pressure, and which allows experimental animals to forget a learned trauma.

  • At the same time, researchers at London University College have just published a study describing how hydrocortisone works — an anti-inflammatory drug commonly used to treat arthritis — could help the process of forgetting intrusive memories if given after a traumatic event.

2- A KNIFE THAT “SMELLS OF TUMORS” DETECTS CANCER IN SECONDS

the British newspaper Keeper revealed in an article the existence of a “smart knife” that can detect uterine cancer in seconds.

  • The device, known as the “iKnife”,was created by a group of researchers from Imperial College London. This cancer is the fourth most common among women.

  • “The iKnife diagnosed endometrial cancer within seconds with 89% certainty, minimizing the current delay for women waiting for histopathological diagnosis,” wrote the team in the magazine tumors.

  • The researchers noted that the effectiveness was tested using biopsy samples from 150 women with suspected uterine cancer and the results were compared to current diagnostic methods. The team plans to conduct a larger clinical trial that could lead to widespread use of the device.

3- SWISS RESEARCHERS CREATE HYDROGEN FUEL WITH SUNLIGHT AND HUMIDITY

A team of Swiss chemical engineers from the Federal Institute of Technology in Lausanne (EPFL) has developed just one technological devicer which produces hydrogen fuel gas from moisture in the air.

  • Researchers have succeeded in developing a new type of transparent gas diffusion electrode, porous and conductive, allowing the conversion of gaseous water into hydrogen fuel.

  • “To achieve a sustainable society, we need ways to store renewable energy in the form of chemicals that can be used as fuels and raw materials in industry,” investigative team chief Kevin Sivula said.

  • Scientists were inspired by the process of photosynthesis in plants, which allows plants to collect carbon dioxide and moisture from their environment and convert them into energy thanks to sunlight.

  • Sivula’s team had previously shown that the artificial processes of photosynthesis can generate hydrogen from liquid water.

  • Researchers’ efforts are now focused on optimizing this system. be able to develop new ways to obtain liquid fuels from hydrogen.

4- THEY DISCOVER THAT DRINKING WATER IS ESSENTIAL TO SLOW DOWN AGING

Adults who hydrate well slow aging, stay healthier and develop fewer chronic conditions than those who don’t get enough fluids. according to a study by the National Institutes of Health (NIH).

  • The study, published in the journal and Biomedicineit is based on data from 11,255 adults, collected over 30 years and on which researchers have analyzed the relationship between blood sodium levels and various health indicators.

  • “The results indicate that proper hydration can slow aging, prolonging a disease-free life,” said Natalia Dmitrieva, one of the study’s authors and a researcher at the Laboratory of Regenerative Cardiovascular Medicine.

5- THE KUMMAKIVI ROCK: 11,000 YEARS OF EQUILIBRIUM AND A CHALLENGE TO THE LAWS OF PHYSICS

A real challenge to the laws of physics is the giant rock known locally as Kummakivi (the “strange stone”), which is located in Ruokolahti, southeast of Finland.

  • What makes the peculiar position of the gigantic rock so interesting is that, despite its enormous size and heavy weight, it appears as if it were floating in the air, in an apparently supernatural equilibrium.

  • The geological formation is even more extraordinary when one considers that it has remained so, perfectly balanced on another rock, for 11,000 years. It measures more than 7 meters wide, about 5 meters high and is estimated to weigh more than 500 tons.

  • Geologists believe that glaciers – capable of hauling such a heavy rock – they left it behind when they returned north more than 8,000 years ago.
