Two holograms in one surface

A team at Caltech has figured out a way to encode more than one holographic image in a single surface without any loss of resolution. The engineering feat overturns a long-held assumption that a single surface could only ...

Creating surfaces that repel water and control its flow

To prevent water and ice from making our shoes soggy, frosting our car windows and weighing down power lines with icicles, scientists have been exploring new coatings that can repel water. Now one team has developed a way ...

Stirring up a quantum spin-liquid with disorder

Disorder is generally thought to be detrimental to creating materials with unusual magnetism or other quantum phenomena. However, a team found that weak disorder surprisingly stabilizes a rare quantum state called a quantum ...

Is there structure in glass disorder?

Stronger than steel yet easily fabricated, bulk metallic glasses are metals that lack an ordered atomic crystalline structure. The mystery of how the atoms are packed in these glasses has been studied for decades. Now, recent ...

Chemical 'pressure' tuning magnetic properties

Unusual, tiny vortexes spinning on the surface of certain magnets could offer a way to reduce the energy demands of computers. Controlling the vortexes is key. Scientists found that chemical substitution in a well-studied ...

New CERN facility can help medical research into cancer

Today, the new CERN-MEDICIS facility has produced radioisotopes for medical research for the first time. MEDICIS (Medical Isotopes Collected from ISOLDE) aims to provide a wide range of radioisotopes, some of which can be ...

Wet plasma makes a nano-sized splash

Oil and water do not mix, but a KAUST team has exploited the distinct interfaces between these substances to make plasma generation in liquids more efficient. This approach holds promise for high-yield synthesis of nanomaterials ...

New manifestation of magnetic monopoles discovered

The startling similarity between the physical laws describing electric phenomena and those describing magnetic phenomena has been known since the 19th century. However, one piece that would make the two perfectly symmetric ...

Brittle starfish shows how to make tough ceramics

An international team lead by researchers at Technion-Israel Institute of Technology, together with colleagues from the European Synchrotron, Grenoble, France, have discovered how an echinoderm called Ophiocoma wendtii, known ...

Scientists watch diamond turn into graphite

In a surprising achievement, a team of scientists has turned diamond into graphite, using an X-ray laser. What may seem undesirable at first glance, is a decisive step forward in understanding the fundamental behaviour of ...

Spontaneous Bose-Einstein condensation of excitons

Excitons are pairs of electrons and holes inside a solid material that together behave like a single particle. It has long been suspected that when many such excitons exist in the same piece of matter, they can form a single ...

Colliding protons head-on

They won't pinch you and you won't find them on the beach. The name of the new radio-frequency crab cavities has nothing to do with their appearance and is merely illustrative of the effect they will have on circulating proton ...
