Series of reactions reveals how complex carbon chemistry can begin in frigid space

Chemists uncover how unthinkable reactions occur in unimaginable conditions

Before there was Earth, there was chemistry. In the unimaginable cold, dark clouds where stars and planets are born, carbon molecules assemble into more complex forms—starting a chemical journey that could eventually deliver some of life’s basic ingredients to young planets. There’s only one problem: These molecules need heat to form. At least that’s what scientists have long believed. But new research from FIU chemist Alexander Mebel reveals such chemistry can actually happen at temperatures nearing absolute zero, which is -460°F (-273°C).

On Earth, these complex carbon molecules are usually associated with extremely hot temperatures, such as those associated with combustion...

Caffeine may flip an ancient cellular switch linked to slower aging

Caffeine May Slow Cellular Aging

Caffeine may help cells age more slowly by switching on a powerful energy and stress-response system. Scientists found that caffeine activates an ancient cellular energy system involved in stress resistance, DNA repair, and growth. The discovery could help explain caffeine’s links to healthier aging and may point toward new ways to target the same pathway.

Your morning coffee may be doing more than helping you wake up.

Research from Queen Mary University of London suggests that caffeine can activate an ancient cellular energy system involved in growth, stress resistance, and DNA repair...

Physicists just found a tiny glitch in time itself

Quantum physics may place a fundamental limit on clock precision, hinting that time itself is not perfectly precise. Unconventional quantum theories may imply that time itself has a tiny fundamental uncertainty, placing an ultimate limit on how precisely any clock could measure it. The effect is far beyond current detection, but it could reveal a hidden connection between quantum mechanics, gravity, and spacetime.

Quantum mechanics has always challenged our everyday understanding of reality. In the quantum world, particles can exist in a superposition of states, meaning they can occupy multiple possible positions or configurations at the same time. Physicists describe these possibilities mathematically using a wavefunction.

That picture is very different from ordinary life, wher...
