Rethinking the incandescent lightbulb

A team of material scientists and engineers affiliated with a host of institutions in China took a new look at the incandescent light bulb and found a way to improve its efficiency. In their paper published in the journal ...

Argon found in air of ancient atmosphere

On the massive sheets of ice that stretch across Greenland and Antarctica, the temperature is so low that not even the summer sun can melt the snow deposited onto them. As the snow accumulates without melting and settles ...

Physicists make discovery about temperature in convection

An international team of physicists is working to ascertain more about the fundamental physical laws that are at work in a process known as convection, which occurs in a boiling pot of water as well as in the turbulent movement ...

Improved Electric Propulsion Could Boost Satellite Lifetimes

(PhysOrg.com) -- Researchers at the Georgia Institute of Technology have won a $6.5 million grant to develop improved components that will boost the efficiency of electric propulsion systems used to control the positions ...

A (much) earlier birth date for tectonic plates

Yale geophysicists reported that Earth's ever-shifting, underground network of tectonic plates was firmly in place more than 4 billion years ago—at least a billion years earlier than scientists generally thought.
