An attosecond—or 0.000000000000000001 second—is no time at all for a person. That is not so for electrons, atoms and ...

As temperature rises, the molecules increase in thermal agitation manifested in linear motion and vibration. Regions that contain higher kinetic energy transfer the energy to regions with lower ...

This article covers the Punjab Board's 2025–2026 Class 11 Physics Syllabus. Class 11 students can download the syllabus in PDF format to become acquainted with the subjects that will be studied during ...

Syllabus: The NTA has put the official JEE Main 2026 Syllabus online on their website: jeemain.nta.nic.in. If you're planning ...

Caltech scientists convert CO2 into tough industrial plastics using a dual-loop system powered by renewable electricity.

Safe and effective high explosives are critical to Lawrence Livermore National Laboratory's (LLNL) mission of stockpile ...

According to physics, any blanket can cool you—for a few minutes. But a real cooling blanket is possible with phase-change materials.

Researchers have identified a form of molecular motion that has not previously been observed. When what are known as "guest molecules"—molecules that are accommodated within a host molecule ...

What makes optical tweezers so fascinating is their versatility. Researchers use them to stretch DNA strands, measure the forces between molecules, and watch how proteins fold or unfold under stress.

B-factor is a measure of ray attenuation or scattering caused by atomic thermal motion during X-ray diffraction of protein crystal structure. B-factor reflects the vibration of atoms; hence, it is the ...

image: The proposed ratchet mechanism utilizes the asymmetry in surface wettability between the smooth and rough faces of the teeth of a geometrically symmetric gear to achieve ratcheting motion ...

1 Knots for life (CC BY 4.0 Polymers 9 454) Some proteins form well-defined knotted structures, as shown above, where the lower image shows a simplified view of each molecule. The number below each ...
