Researchers boost intensity of nanowire LEDs Posted: 21 Mar 2019 10:04 AM PDT Nanowire researchers have made ultraviolet light-emitting diodes (LEDs) that, thanks to a special type of shell, produce five times higher light intensity than do comparable LEDs based on a simpler shell design. |
Posted: 21 Mar 2019 10:04 AM PDT Researchers have synthesized a tiny structure from 32 gold atoms. This nanocluster has a core of 12 gold atoms surrounded by a shell of 20 additional gold atoms. The unusual stability of this cluster results from electronic interactions with amido and phosphine ligands bound to its surface. |
Blue Brain solves a century-old neuroscience problem Posted: 21 Mar 2019 10:04 AM PDT New research explains how the shapes of neurons can be classified using mathematical methods from the field of algebraic topology. Neuroscientists can now start building a formal catalogue for all the types of cells in the brain. Onto this catalogue of cells, they can systematically map the function and role in disease of each type of neuron in the brain. |
How measurable is online advertising? Posted: 21 Mar 2019 10:04 AM PDT New research sheds light on whether common approaches for online advertising measurement are as reliable and accurate as the 'gold standard' of large-scale, randomized experiments. |
In a new quantum simulator, light behaves like a magnet Posted: 21 Mar 2019 10:03 AM PDT Physicists propose a new 'quantum simulator': a laser-based device that can be used to study a wide range of quantum systems. Studying it, the researchers have found that photons can behave like magnetic dipoles at temperatures close to absolute zero, following the laws of quantum mechanics. The simple simulator can be used to better understand the properties of complex materials under such extreme conditions. |
Making solar cells is like buttering bread Posted: 21 Mar 2019 10:03 AM PDT Formamidinium lead iodide is a very good material for photovoltaic cells, but getting the correct and stable crystal structure is a challenge. The techniques developed so far have produced rather poor results. However, scientists have now cracked it -- using a blade and a dipping solution. |
Geophysics: A surprising, cascading earthquake Posted: 21 Mar 2019 10:03 AM PDT The Kaikoura earthquake in New Zealand in 2016 caused widespread damage. Researchers have now dissected its mechanisms revealing surprising insights on earthquake physics with the aid of simulations carried out on a supercomputer. |
Physicists reveal why matter dominates our universe Posted: 21 Mar 2019 10:03 AM PDT Physicists have confirmed that matter and antimatter decay differently for elementary particles containing charmed quarks. |
Organic semiconductors: One transistor for all purposes Posted: 21 Mar 2019 10:03 AM PDT In mobiles, fridges, planes -- transistors are everywhere. But they often operate only within a restricted current range. Physicists have now developed an organic transistor that functions perfectly under both low and high currents. |
New microscope captures large groups of neurons in living animals Posted: 21 Mar 2019 07:28 AM PDT Researchers have developed a microscope specifically for imaging large groups of interacting cells in their natural environments. The instrument provides scientists with a new tool for imaging neurons in living animals and could provide an unprecedented view into how large networks of neurons interact during various behaviors. |
True-meaning wearable displays: Self-powered, washable and wearable Posted: 21 Mar 2019 07:28 AM PDT When we think about clothes, they are usually formed with textiles and have to be both wearable and washable for daily use; however, smart clothing has had a problem with its power sources and moisture permeability, which causes the devices to malfunction. This problem has now been overcome by a research team, who developed a textile-based wearable display module technology that is washable and does not require an external power source. |
First reputation-based blockchain guarantees security against 51 percent attacks Posted: 21 Mar 2019 07:28 AM PDT Researchers have proposed the first blockchain system to guarantee proper performance even when more than 51 percent of the system's computing power is controlled by an attacker. |

Unprecedented privacy risk with popular health apps Posted: 21 Mar 2019 06:22 AM PDT Researchers call for greater regulation and transparency as analysis of medicines-related apps found most directly shared user data -- including sensitive health data -- with third parties, posing an unprecedented privacy risk. |
Adhesive gel bonds to eye surface, could repair injuries without surgery Posted: 20 Mar 2019 11:10 AM PDT An adhesive gel packed with light-activated chemicals can seal cuts or ulcers on the cornea -- the clear surface of the eye -- and then encourage the regeneration of corneal tissue, according to a preclinical study. The new technology, named GelCORE (gel for corneal regeneration), could one day reduce the need for surgery to repair injuries to the cornea, including those that would today require corneal transplantation. |
'Terminator'-like liquid metal moves and stretches in 3D space Posted: 20 Mar 2019 07:22 AM PDT In the blockbuster 'Terminator' movie franchise, an evil robot morphs into different human forms and objects and oozes through narrow openings, thanks to its 'liquid-metal' composition.
