Stretching diamond for next-generation microelectronics

Diamond is the hardest material in nature. But out of many expectations, it also has great potential as an excellent electronic material. A joint research team led by City University of Hong Kong (CityU) has demonstrated for the first time the large, uniform tensile elastic straining of microfabricated diamond arrays through the nanomechanical approach. Their findings have shown the potential of...

Light-responsive E. coli functional biofilms as scaffolds for hydroxyapatite mineralization

Living organisms have evolved mechanisms of biomineralization to build structurally ordered and environmentally adaptive composite materials. While research teams have significantly improved biomimetic mineralization research in the lab, it is still difficult to engineer mineralized composites with structural features and living components much like their native counterparts. In a new report now...

The map of nuclear deformation takes the form of a mountain landscape

Until recently, scientists believed that only very massive nuclei could have excited zero-spin states of increased stability with a significantly deformed shape. Meanwhile, an international team of researchers from Romania, France, Italy, the USA and Poland showed in their latest article that such states also exist in much lighter nickel nuclei. Positive verification of the theoretical model used...

Scientists further improve accuracy of directional polarimetric camera

Recently, researchers from the Optical Remote Sensing Center of the Anhui Institute of Optics and Fine Mechanics (AIOFM), Hefei Institutes of Physical Science (HFIPS) have successfully improved the accuracy of directional polarimetric camera (DPC) laboratory polarization calibration via new methods.

ATLAS project finds 12 new species of sea creatures

Researchers working with the ATLAS project have reported to the press that they have found 12 new species of sea creatures new to science. The EU funded undersea project has been ongoing for five years and has carried out 45 research expeditions that involved the work of over 80 scientists and student volunteers.

Fish sex organs boosted under high CO2

Research from the University of Adelaide has found that some species of fish will have higher reproductive capacity because of larger sex organs, under the more acidic oceans of the future.

Organic meats found to have approximately the same greenhouse impact as regular meats

A trio of researchers from the Technical University of Munich, the University of Greifswald and the University of Augsburg have found that the meat production process for organic meats produces approximately the same amounts of greenhouse gases as does the conventional meat production process. In their paper published in the journal Nature Communications, Maximilian Pieper, Amelie Michalke and...

Designing Dirac vortex topological photonic crystal fibres

Optical fibres made of topological photonic crystals allow improved versatility and control across the modes and polarization of light they transmit. Compositionally, photonic crystals contain bandgaps to prevent the passage of light relative to specific wave energies and momenta much like an on/off switch. In a new report now published on Nature Light: Science & Applications, Hao Lin, and Ling Lu...

The puzzle of nonhost resistance: why do pathogens harm some plants but not others?

People have puzzled for years why pathogen Phytophthora infestens causes the devastating late blight disease, source of the Irish Potato famine, on potatoes, but has no effect at all on plants like apple or cucumber. How are apple trees and cucumber plants able to completely shake off this devastating pathogen? Agricultural scientists have wondered for years: if this resistance is so complete and...
