Descoberta a explicação biológica para todos nós termos um sósia
Andrea Jiménez 
Como acaba de demonstrar biologicamente o Instituto de Investigación contra la Leucemia Josep Carreras (IJC), todos temos um sósia no mundo. Uma fascinante afirmação concluída graças à equipe do centro catalão que descobriu que as pessoas extremamente parecidas, porém sem relação de parentesco, compartilham características genéticas nos genes responsáveis pela formação dos traços faciais./.../

Four videos combined in a single video to make it easy to understand protein synthesis in a living cell. It is indeed a very complex process. Only reading texts often isn't enough for better understanding of the topic. #ProteinBiosynthesis #ProteinSynthesis video 1. https://youtu.be/gG7uCskUOrA 0:00 video 2. https://youtu.be/G8RYhV569xg 2:55 video 3. https://www.youtube.com/watch?v=2BwWa... 8:42 video 4. https://youtu.be/TfYf_rPWUdY 16:02 #ProteinSynthesis #Animation

Blob Hunting
A hot blob of gas is orbiting our galaxy’s central black hole, Sagittarius A*, at nearly one third the speed of light, reports Harry Baker for Live Science. Since the first photo of SagA* was released early this year, the picture has provided new insights into how galaxies form. But it has also unveiled new puzzles. Thomas Lewton wrote about these for Quanta in August.

In a 1st, scientists use designer immune cells to send an autoimmune disease into remission
(NANOCLUSTERING/SCIENCE PHOTO LIBRARY via Getty Images)
Five patients with hard-to-treat lupus entered remission after scientists tweaked their immune cells using a technique normally used to treat cancer. After the one-time therapy, all five patients with the autoimmune disease stopped their standard treatments and haven't had a relapse.

This treatment, known as chimeric antigen receptor (CAR) T-cell therapy, needs to be tested in larger groups of lupus patients before it can be approved for widespread use. But if the results hold up in larger trials, the therapy could someday offer relief to people with moderate to severe lupus.

“Republicans and Democrats overestimate the extent to which the other side dehumanizes them by 50–300%, and debunking these misperceptions can reduce rates of animosity.”

Correcting misconceptions about how we are seen by the ‘other side’ is one intervention that can successfully reduce extreme political sectarianism, write 12 psychologists and political scientists. (Nature Human Behaviour paper | 46 min read)

Past Quanta Coverage of 2023 Breakthrough Prize Winners
The 2023 Breakthrough Prize in Fundamental Physics was awarded to four pioneers of quantum information science: Charles Bennett, Gilles Brassard, David Deutsch and Peter Shor. Dan Garisto reports on the awards for Scientific American.
• Among his many contributions to physics, Charles Bennett solved the longstanding paradox of Maxwell’s demon, as Jonathan O’Callaghan explained for Quanta in 2021. Bennett’s insights linked the studies of information and thermodynamics as disciplines.
• David Deutsch contributed immensely to our understanding of quantum mechanics and the universe. In May, Philip Ball wrote for Quanta about his most recent accomplishment: Deutsch rewrote the laws of physics in terms of simple statements about what is possible.
• Peter Shor’s discoveries revolutionized quantum computing. In consecutive years, he devised his famous encryption-breaking algorithm and figured out how quantum computers will correct their errors. In 2021 Katie McCormick explained how Shor’s error-correction scheme work.

The 2023 Breakthrough Prize in Mathematics was awarded to the computer scientist Daniel Spielman for multiple discoveries in theoretical computer science and mathematics. Spielman spoke with Quanta about his work this past summer.

Three 2023 Breakthrough Prizes in Life Sciences were also announced yesterday, honoring three pairs of scientists for their work: Clifford P. Brangwynne and Anthony A. Hyman, Demis Hassabis and John Jumper, and Emmanuel Mignot and Masashi Yanagisawa. Amanda Heidt reports on the awards for The Scientist.
• Brangwynne and Hyman were recognized for their studies that showed the importance of liquid-liquid phase separation as a means for organizing cellular contents without membrane barriers. Viviane Callier wrote for Quanta about their work in 2021.
• Yanagisawa and Mignot were recognized for their discovery of the genetic switches that cause the brain to sleep, and which malfunction in narcolepsy. Veronique Greenwood wrote about their work for Quanta in 2017.
• Hassabis and Jumper were honored for developing the program AlphaFold, which revolutionized the prediction of protein structures. Stephen Ornes wrote about the transformer neural networks that are an important component of AlphaFold in March.

Child mortality: an everyday tragedy of enormous scale that we can make progress against

Child mortality is an everyday tragedy of enormous scale that rarely makes the headlines. We live in a world in which 5.4 million children die every year. That’s 10 dead children every minute.

But progress against child mortality is possible. In this article from July 2021, we describe how child mortality has decreased across all countries in the world — but there is large inequality between rich and poor countries, and much progress still to make.
