Researchers at MIT have invented a temporary “tattoo” made from genetically programmed living cells. Their prototype looks like a stick-on patch with a pattern in the shape of a tree.   It’s divided into sections printed with a slurry containing live bacteria that fluoresce when they come into contact with particular compounds. When the skin under

An international team of scientists employed highly precise methods to uncover the most exact measurement of the magnetic moment of protons. They found it to be 2.79284734462, plus-or-minus 0.00000000082 nuclear magnetons (the typical unit for measuring this property).   The magnetic moment is a property of particles that is a prerequisite for magnetism, and applied

For the first time, scientists have witnessed lightning triggering nuclear reactions in the atmosphere, confirming a hypothesis dating back almost a century. It’s long been predicted that high-energy electrons in lightning can produce gamma rays that induce nuclear reactions in thunderclouds, but before now, the phenomenon has never been conclusively observed.   “The photonuclear reaction

During the mid- to late-twentieth century, quantum physicists picked apart the unified theory of physics that Einstein’s theory of relativity offered. The physics of the large was governed by gravity, but only quantum physics could describe observations of the small. Since then, a theoretical tug-o-war between gravity and the other three fundamental forces has continued

In the science of quantum communication, the challenge has always been prolonging the entangled state that the particles are in. As quantum information is carried by these entangled particles, the length of time the entanglement is sustained affects the distance that the information can travel.   Quantum communication systems do this using direct optical-fiber connections,

Proteins, the building blocks in every cell, have usually been thought of as blobs of inert organic matter. Now scientists have caught one particular protein doing something incredible: conducting electricity. If the findings can be replicated and used, we could have ourselves a powerful new diagnostic tool for medical use, capable of identifying single protein

A team of researchers from RMIT University in Melbourne, Australia has reportedly made a ‘once-in-a-decade discovery’ that will radically change how we do chemistry. The discovery? The creation of two-dimensional materials no thicker than a few atoms — something that’s never been seen before in nature.   The research that led to this incredible find was led

Researchers have at last been able to model the behaviour of electrons under extreme densities and temperatures, similar to those found inside stars and planets. Although electrons are ubiquitous in our universe, carrying electrical current and determining the physical properties of materials, physicists have never before been able to describe the ways large numbers of

Jacques Dubochet, Joachim Frank and Richard Henderson have won the Nobel Prize in chemistry “for developing cryo-electron microscopy for the high-resolution structure determination of biomolecules in solution,” the Nobel committee announced Wednesday. Cryo-electron microscopy is “a cool method for imaging the materials of life,” said Nobel committee member Göran K. Hansson from Stockholm. The development

Since the mid-twentieth century, two theories of physics have offered powerful yet incompatible models of the physical universe. General relativity brings space and time together into the (then) portmanteau space-time, the curvature of which is gravity. It works really well on large scales, such as interplanetary or interstellar space. But zoom into the subatomic, and

Scientists have discovered the existence of a type of particle that’s never previously been observed, which demonstrates unprecedented chemical stability for its kind. It’s big news for chemists and physicists – but the achievement isn’t just exciting for theoretical scientists, because, if researchers can figure out how to make it in the lab, it could
