A team of physicists from the University of Birmingham and the University of Bath has identified a method to visualize, over a millionth of a billionth of a second, the initial quantum behavior of electrons on a surface. The scanning tunneling microscope used to inject electrons into a silicon surface. …

The Universe is not spinning or stretched in any particular direction, according to a team of researchers from University College London and Imperial College London, UK. A massive cluster of yellowish galaxies, seemingly caught in a red and blue spider web of eerily distorted background galaxies, makes for a spellbinding …

An Iowa State University-led team of physicists has demonstrated the quasi-stable existence of a tetraneutron, a subatomic structure once thought unlikely to exist.

An international team of physicists, led by Prof. Chris Greene from Purdue University and Prof. Herwig Ott from the University of Kaiserslautern, has observed a butterfly Rydberg molecule, a weak pairing of two highly excitable atoms. Their work was published in the Oct. 5 issue of the journal Nature Communications …

According to a team of researchers at the Tata Institute of Fundamental Research (TIFR) in Mumbai, India, pure bismuth — a semimetal with a rhombohedral structure — is superconducting at ultra-low temperatures.

There are two states of liquid water, says an international team of physicists led by Oxford University’s Dr. Laura Maestro. L.M. Maestro et al find that two states of liquid water play an important role in the thermal and optical properties of nanomedical systems; the team’s preliminary findings also suggest …

An international team of scientists from Japan, UK and the United States has been able to regenerate heart muscle by placing adult mice in a low-oxygen environment.

A Northwestern University-led team of researchers has identified a region in the brain responsible for the ‘placebo effect’ in pain relief, when a fake treatment actually results in substantial reduction of pain. In the study, whole-brain degree count maps, collected before the start of treatment, were used to identify potential …

An international team of scientists from the United States and China has found a sensor for the reactive molecules linked to diabetic complications. The study, done in the nematode worm Caenorhabditis elegans, provides particular promise for those suffering from painful diabetes-related nerve damage. TRPA-1/TRPA1 activation via a-dicarbonyls (a-DCs) is relayed …
