They measure the nuclear force with the highest precision achieved to date

Thanks to more than 8,000 experimental data obtained in particle accelerators in different parts of the world between 1950 and 2013, a group of scientists from the University of Granada (UGR) has managed to measure the nuclear force in the most precise way so far.

They manage to catch and move nano-objects in 3D with optical nano-tweezers

A team of researchers from the Institute of Photonic Sciences (ICFO) in Barcelona has managed for the first time in history to capture and move a nano-object in 3D using only the force of light, thanks to nano-sized optical tweezers. The study has been published in the journal Nature Nanotechnology.

They discover a new particle: the dropleton

A team of physicists from the University of Marburg (Germany) and the JILA center (University of Colorado Boulder-NIST) has discovered a new type of quasiparticle formed by a handful of electrons and holes (where there are no electrons) which they have named as "dropleton". Its name comes from the English word "droplet" (drop), since this quantum drop has part particle and part liquid.

Science is more surprising than science fiction

The world of science fiction has transported us to hyperspace and has anticipated major scientific advances on many occasions. However, according to the latest study by Professor Lawrence Krauss of Arizona State University, science fiction has always been inspired by the cutting edge science of the time.

Record the most accurate atomic mass of the electron

A team of scientists led by the Max Planck Institute for Nuclear Physics has achieved a milestone in this matter: recording the most accurate figure ever achieved for the atomic mass of the electron. The results of the study have been published in the journal Nature.

In this chapter of The Big Bang Theory the protagonists apply the famous Drake equation, normally used to calculate the chances of contacting intelligent extraterrestrial beings, to the chances of ending up hooking up in a disco.

Does the LHC need a substitute?

The Large Hadron Collider or LHC will be operational again in early 2015, and its tasks are already scheduled for the next 20 years. However, will the LHC need a replacement by then?

Scientists create the first magnetic monopole

A group of researchers from Aalto University (Finland) and Amherst College (USA) have succeeded in creating the first single-pole magnet in a laboratory. It is a milestone that will revolutionize the world of physics, by opening the possibility of discovering new particles of nature, unthinkable until now. The results have been published in the journal Nature.
