Phys.org / Why only a small number of planets are suitable for life

For life to develop on a planet, certain chemical elements are needed in sufficient quantities. Phosphorus and nitrogen are essential. Phosphorus is vital for the formation of DNA and RNA, which store and transmit genetic ...

Phys.org / A smashing success: Relativistic Heavy Ion Collider wraps up final collisions

Just after 9 a.m. on Friday, Feb. 6, 2026, final beams of oxygen ions—oxygen atoms stripped of their electrons—circulated through the twin 2.4-mile-circumference rings of the Relativistic Heavy Ion Collider (RHIC) and ...

Phys.org / How big can a planet be? With very large gas giants, it can be hard to tell

Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't have hard surfaces. Jupiter and Saturn are the gas giants in our solar system, but there are many ...

Phys.org / From fins to fingers: How nature 'redeployed' ancient genes to shape limbs

How did the complexity of many organisms living today evolve from the simpler body plans of their ancestors? This is a central question in biology. Take our hands, for example: Every time we type a message on our mobile phone, ...
