Researchers have devised a new way to separate cells by exposing them to sound waves as they flow through a tiny channel. Separating cells with sound offers a gentler alternative to existing cell-…

Scientists have mapped quantum tornadoes that swirl within tiny droplets of liquid helium, which confirms that helium nanodroplets are in fact the smallest possible superfluidic objects and opens new…

By Peter Gwynne, Inside Science Why don't we suffocate whenever we try to take a breath? An international team of scientists has used quantum mechanics – the science that usually deals with events at…

New measurements of atomic-scale magnetic behavior in iron-based superconductors are challenging conventional wisdom about superconductivity and magnetism.  Superconductivity is strongly…

The moon is a tranquil place but an article in the Journal of Geophysical Research-Planets suggests that periodic storms of solar energetic particles may have significantly altered the properties of…

The structural components of advanced reactors such as the sodium fast reactor and the traveling wave nuclear reactor must be able to withstand the extreme levels of radioactivity from the fission…

Researchers have created highly focused pathways that can channel electricity through the atmosphere. It's not a new idea, Nikola Tesla worked on powering wireless lamps using electrostatic induction…

It’s true. Here’s my 555 Guituner circuit: go to 50 – 555 circuits web page on talkingelectronics.com and search for “guitar tuner” and you will find my circuit. Actually they’ve modified it slightly…

Laser physicists have found a way to make atomic-force microscope probes 20 times more sensitive, using laser beams to cool a nanowire probe to minus 265 degrees Celsius.  Atomic force…

If you've ever spent any time watching a gecko, you've been impressed by their uncanny ability to adhere to any surface - including upside down on ceilings.  A new study in the Journal of…
