In this documentary, wealthy entrepreneur Bryan Johnson puts his body and fortune on the line to defy aging and extend his life beyond all known limits.
Summary: Time perception varies depending on context, often slowing in emergencies or unfamiliar settings and speeding up during absorption or as we age. Time expansion experiences (Tees) occur when seconds stretch into minutes, frequently in accidents, sports, or moments of calm. These experiences, often tied to altered states of consciousness, allow people to process more information and act decisively.
While theories link Tees to noradrenaline release or evolutionary adaptation, their occurrence in peaceful states suggests a deeper connection to changes in self-perception and awareness. Understanding Tees could offer insights into human cognition and survival mechanisms.
A new study explores tetraquarks, predicts new exotic particles, and offers deeper insights into their complex structure and behavior.
A new study offers significant advancements in the understanding of tetraquarks — a rare and complex type of particle.
By developing a new approach that combines advanced mathematical methods with a simpler model of how particles interact, the researchers have made important discoveries about the inner structure and mass of these particles.

How sleep microstructure organizes memory replay.
T occur in isolation; older memories are also replayed during sleep, raising an intriguing challenge: how does the brain avoid interference between fragile new memories and stable old ones?” + To explore this question, researchers developed a groundbreaking method to study both hippocampal activity and sleep dynamics simultaneously in naturally sleeping mice. Using a technique called pupillometry, which measures oscillatory changes in pupil size, they uncovered a previously unknown “microstructure” within non-REM sleep that helps the brain manage memory replay.
They discovered that memory replay is organized into distinct substates of non-REM sleep:

Apple could bring Samsung into its camera sensor supply chain, with a new rumor claiming that it is developing a new 3-layer stacked sensor.
The small step back to Earth’s satellite will provide a giant leap for exploring our solar system.
Astronomy enthusiasts, brace yourselves for a dazzling display as the Quadrantids, the first meteor shower of 2025, light up the sky.
The Quadrantids are unique among meteor showers as they originate from debris left by an asteroid, rather than a comet. This shower, best viewed in the Northern Hemisphere, is renowned for its bright fireballs and has been described by NASA as one of the strongest and most consistent meteor showers of the year. However, the peak visibility window is relatively short, lasting just six hours on the night of Jan. 2 into Jan. 3, and winter weather conditions such as frigid temperatures and overcast skies may challenge observers.
The Quadrantids are named after Quadrans Muralis, an 18th-century constellation astronomers no longer use. Both the constellation and the shower are named after an instrument called the quadrant, which was once used to measure the altitudes of stars and other bodies in the night sky.
Research reveals distinct mechanisms underlying neonatal and post-pubertal social behaviors, providing valuable insights for developing targeted early interventions.
Researchers from the University of Texas Health Science Center at San Antonio and Hirosaki University have unveiled significant findings on the development of social behaviors in fragile X syndrome, the most common genetic cause of autism spectrum disorder. The study, published in Genomic Psychiatry, highlights the effects of a specific prenatal treatment on social behaviors in mice.
The researchers found that administering bumetanide—a drug that regulates chloride levels in neurons—to pregnant mice restored normal social communication in newborn pups with the fragile X mutation. However, they also discovered an unexpected outcome: the same treatment reduced social interaction after puberty in both fragile X and typical mice. These findings shed light on the complex and developmental-stage-specific effects of interventions for fragile X syndrome.
