The mosquitoes that are outside the wall seem blocked   You’re in the middle of a great chat with friends on a warm summer night, and then “ouch” a mosquito interrupts your conversation with a bite on your forearm. Experimental physicist Szabolcs Marka hopes to make this occurrence a thing of the past, but in

A mid-air display of ‘floating pixels’ has been created by scientists. Researchers at the Universities of Sussex and Bristol have used soundwaves to lift many tiny objects at once before spinning and flipping them using electric force fields. The technology – called JOLED – effectively turns tiny, multi-coloured spheres into real-life pixels, which can form

30 percent more than the Department of Defense’s Robust Electric Laser Initiative (RELI) requirements The likelihood of lasers appearing on the battlefield was boosted last week when Boeing announced that its Thin Disk Laser system had achieved unexpected levels of power and efficiency. In a recent demonstration for the US Department of Defense, the laser’s

A team of scientists from the Moscow Institute of Physics and Technology (MIPT) have created prototypes of “electronic synapses” based on ultra-thin films of hafnium oxide (HfO2). These prototypes could potentially be used in fundamentally new computing systems. The paper has been published in the journal Nanoscale Research Letters. The group of researchers from MIPT

Wind turbines are being placed too close together While there are increasing numbers of large wind farms being built around the world, many of these projects are underperforming and not producing as much power as expected. New research suggests the reason could be that the wind turbines are being placed too close together. The researchers say

Removing a brain tumor is a delicate task, if not done properly it can have catastrophic consequences, such as brain damage, motor impairment or failure in controlling a vital organ function. In order to make this work more precise, the Mexican David Oliva Uribe designed, at Brussels, Belgium, a “smart scalpel” that determines whether an

Theorists Predict New Single-Layer Material Could Go Beyond Graphene, Conducting Electricity with 100 Percent Efficiency at Room Temperature A single layer of tin atoms could be the world’s first material to conduct electricity with 100 percent efficiency at the temperatures that computer chips operate, according to a team of theoretical physicists led by researchers from

A new strategy for developing drugs to treat cancer, multiple sclerosis, Alzheimer’s and cardiovascular diseases. Researchers at the University of Houston (UH) are recommending a new strategy for developing drugs to treat cancer, multiple sclerosis, Alzheimer’s and cardiovascular diseases. In an invited review published in the October issue of Nature Reviews Drug Discovery, scientists at

  Scientists are reporting development of what they describe as the first self-healing protective coating for cracks in concrete, the world’s most widely used building material. Their study on the material — which is inexpensive and environmentally friendly — appears in the journal ACS Applied Materials & Interfaces. Chan-Moon Chung and colleagues explain that protecting concrete

Image via Wikipedia For phosphor-based light-emitting diodes(LEDs) to continue their current trend of displacing incandescent and fluorescent bulbs, makers of these small semiconductor-based lights are looking to, among other things, continue improvements in energy efficiency, increase longevity and reduce glare. LEDs are illuminated by the movement of electrons in a semiconductor material, but the common practice
