The New Glenn rocket’s seven powerful engines may light up as soon as today
"Maybe, maybe, maybe today, maybe soon. I think it's very soon." In a widely anticipated test, Blue Origin may ignite the seven main engines on its New Glenn rocket as soon as Thu.....»»
Extended chart of life shows ancient species may have evolved slower and lasted longer
If all the world's a stage and all the species merely players, then their exits and entrances can be found in the rock record. Fossilized skeletons and shells clearly show how evolution and extinction unfolded over the past half a billion years, but.....»»
Prototype sunscreen uses TiO₂ nanoparticles to cool skin while blocking UV rays
Wearing sunscreen is important to protect your skin from the harmful effects of UV radiation but doesn't cool people off. However, a new formula, described in Nano Letters, protects against both UV light and heat from the sun using radiative cooling......»»
Webb offers best glimpse ever into icy planetesimals of early solar system
New studies led by researchers at the University of Central Florida offer for the first time a clearer picture of how the outer solar system formed and evolved based on analyses of trans-Neptunian objects (TNOs) and centaurs......»»
Scientists recreate molecular timers to control nanomachine activation rates
Living organisms monitor time—and react to it—in many different ways, from detecting light and sound in microseconds to responding physiologically in pre-programmed ways, via their daily sleep cycle, monthly menstrual cycle, or to changes in the.....»»
Optical spring enables programmable defect mode in new mechanical crystal
Mechanical crystals, also known as phononic crystals, are materials that can control the propagation of vibrations or sound waves, just like photonic crystals control the flow of light. The introduction of defects in these crystals (i.e., intentional.....»»
