Robotic RoboBees Achieve First Controlled Flight

Robotic RoboBees Achieve Flight

A new study and video details the first controlled flight of robotic RoboBees. Last summer, in a Harvard robotics laboratory, an insect took flight. Half the size of a paper clip, weighing less than a tenth of a gram, it leapt a few inches, hovered for a moment on fragile, flapping wings, and then sped […]

3D Printed “Bionic” Ear Exhibits Enhanced Auditory Sensing

Scientists Use 3D Printing and Nanoparticles to Create a Functional Ear

Researchers at Princeton created a 3D printed “bionic” ear that exhibits enhanced auditory sensing for radio frequency reception, merging biologic and nanoelectronic functionalities via 3D printing. Scientists at Princeton University used off-the-shelf printing tools to create a functional ear that can “hear” radio frequencies far beyond the range of normal human capability. The researchers’ primary […]

Adaptive Optics Improve Measurements of the Properties of Stars

Astronomers Observe Globular Cluster NGC 6496

Using a new instrument dubbed SAM, astronomers demonstrated the significant difference that sharp stellar images can make in our understanding of the properties of stars, allowing astronomers to make more precise measures of the colors of the stars and better measurements of distance, age, and metallicity of globular clusters. Astronomers at the Southern Observatory for […]

Researchers Use Data from CERN to Measure Antimatter Gravity Directly

Researchers Use Data from CERN to Measure Antimatter Gravity Directly

In a new study, physicists from the Berkeley Lab and UC Berkeley used data from the ALPHA Experiment at CERN to measure antimatter gravity directly, presenting the first direct evidence of how atoms of antimatter interact with gravity. The atoms that make up ordinary matter fall down, so do antimatter atoms fall up? Do they […]

New Approach Improves Biomass-to-Fuel Process

Researchers Improve Biomass to Fuel Process

A newly published study describes a new approach to converting non-food based biomass into fuels, allowing researchers to generate a range of alkanes from a variety of biomass-derived molecules. Los Alamos, New Mexico — One of the more promising roads to energy independence leads away from crude oil and into the forests and fields. For […]

Scientists Reveal Saturn’s Youthful Appearance is the Result of Layered Convection

Researchers Discover Why Saturn Appears Young

In a new study, scientists from the University of Exeter and the Ecole Normale Supérieure de Lyon reveal that Saturn’s youthful appearance is due to its inability to cool down, suggesting that the interior structure, composition and thermal evolution of giant planets may be more complex than the conventional approximation of giant planets as homogeneous […]

VLA Identifies Discrete Sources of Radio Waves Coming from Distant Galaxies

VLA Gives Detailed Image of Distant Universe

Using data from the Very Large Array, astronomers have for the first time identified discrete sources that account for nearly all the radio waves coming from distant galaxies. Staring at a small patch of sky for more than 50 hours with the ultra-sensitive Karl G. Jansky Very Large Array (VLA), astronomers have for the first […]

NASA’s Fermi Dodges a Defunct Cold War Spy Satellite

NASAs Fermi Nearly Collides With a Defunct Cold War Spy Satellite

NASA’s Fermi Gamma-Ray Space Telescope has a close call with the 3,100-pound Cosmos 1805, a defunct Cold-War spy satellite, avoiding a near collision. NASA scientists don’t often learn that their spacecraft is at risk of crashing into another satellite. But when Julie McEnery, the project scientist for NASA’s Fermi Gamma-ray Space Telescope, checked her email […]

Chandra Reveals an Enormous Cloud of Hot Gas Enveloping Two Colliding Galaxies

Enormous Cloud of Hot Gas Enveloping Two Colliding Galaxies

A burst of star formation that lasted for at least 200 million years may be responsible for a cloud of hot gas, which contains the mass of 10 billion Suns, spans 300,000 light years, and radiates at more 7 million degrees, that is surrounding two merging spiral galaxies. Scientists have used Chandra to make a […]

Scientists Control Chirality in Carbon Nanotubes

Controlling Chirality in Nanotubes

A team of researchers have managed to control chirality in carbon nanotubes, achieving an epitaxial formation of Co nanoparticles by reducing a well-developed solid solution in CO. An ultimate goal in the field of carbon nanotube research is to synthesize single-walled carbon nanotubes (SWNTs) with controlled chiralities. Twenty years after the discovery of SWNTs, scientists […]

Researchers Increase the Stiffness of Silicone Liquid Crystal by 90 Percent

Silicone Liquid Crystal May Lead to Self Healing Materials

In a newly published study, researchers from Rice University report that the liquid crystal phase of silicone becomes 90 percent stiffer when silicone is subjected to a low-amplitude (5%), repetitive (dynamic) compression. Houston – Squeeze a piece of silicone and it quickly returns to its original shape, as squishy as ever. But scientists at Rice […]
