Computer scientist Alexei Efros suffers from poor eyesight, but this has hardly been a professional setback. It’s helped him understand how computers can learn to see. At the Berkeley Artificial Intelligence Research Lab (BAIR), Efros combines massive online data sets with machine learning algorithms to understand, model and re-create the visual world. His work is […]

As the most complex organ in your body, your brain changes radically throughout your life. Starting from before birth and continuing even after you’ve died. This is what happens to your brain as you age.
What if we could slow down the hands of our biological clocks? This question underpins much of the research of Morgan Levine, who leads a research team at the life science company Altos Labs. Levine investigates the fascinating intricacies of aging, recognizing that it doesn’t happen at a uniform pace for everyone. Central to her […]
Dr. Morgan Levine, author of «True Age,» explains how the impact of diet on aging and longevity is determined by three factors: quantity, quality, and timing of food intake. First, caloric restriction, typically a 20% reduction in overall calorie intake, has been linked to increased lifespan in several animal models. However, the positive effects may […]
Richard Reeves, a senior fellow at the Brookings Institution, discusses the importance of friendships and the potential “friendship recession.” He notes that loneliness can be as harmful as smoking 15 cigarettes per day, but measuring and quantifying friendships is difficult. According to Reeves, an ideal number of close friends is around three or four. But […]
Bo Seo, an author and two-time world debate champion, believes our public conversations are in crisis. To Seo, our arguing skills have collectively atrophied over recent decades, resulting in bad arguments that have caused many people to lose faith in the idea that productive disagreements are even possible. That’s why Seo suggests a framework called […]
SS 433 stands out as one of the most intriguing objects within our Milky Way. At its core, a black hole draws material from a closely orbiting companion star, creating a hot accretion disk. Notably, a pair of oppositely directed beams of plasma («jets») spirals away perpendicularly from the disk’s surface at just over a […]
Antifragility is the idea of putting pressure on a system, or human, the system or human actually grows bigger and stronger. Antifragile systems are all around us. One example of this is our muscular system. We go to the gym to lift weights. By doing so we are putting pressure on our system to help […]

Agencia SINC Uno de los mayores misterios en la historia de las epidemias es si la sífilis fue introducida en Europa tras el primer viaje de Colón a las Américas. Ahora, un estudio, liderado por la Universidad de Basilea (Suiza), ha confirmado la presencia de una de las enfermedades treponematósicas, llamada bejel (enfermedad similar a la sífilis), […]
