New radio chip mimics human ear, could enable universal radio

Location: Cambridge, United States

MIT engineers have built a fast, ultra-broadband, low-power radio chip, modeled on the human inner ear, that could enable wireless devices capable of receiving cell phone, Internet, radio and television signals. Rahul Sarpeshkar, associate...

Traffic Modeling - Phantom Traffic Jams and Traveling Jamitons

Location: Cambridge, United States

Countless hours are lost in traffic jams every year. Most frustrating of all are those jams with no apparent cause -- no accident, no stalled vehicle, no lanes closed for construction. Such phantom jams can form when there is a heavy volume of...

A new approach to engineering for extreme environments

Location: California, United States

Composite materials such as fiberglass, which take on a mix of properties of their constituent compounds, have been around for decades. Now, an MIT materials scientist is taking composites to the nanoscale, where entirely new properties, not found...

Hydro-Hydraulic Energy Invention

Location: Islamabad, Pakistan

A researcher in Pakistan has been working hard to develop new hydro technologies like this hydro power invention. His latest research features the run of river active setup of micro hydro power generation blended with basic principals of...

Metal Nanostructures for Optical Sensing and Signaling

Location: California, United States

The aim of this research is to develop devices based upon two dimensional arrays of metallic nanoparticles, with an optical signatures that are tunable and can measure changes their environment. We have synthesized silver nanoparticles of 3-6 nm...

Athermal Holographic Filters

Location: California, United States

Abstract: Holographic filters are used as optical sensors and in wavelength division multiplexing (WDM) filtering applications. Temperature dependence is a critical concern for telecommunications. Researcher realize the design of an athermal...

A way to slow concrete creep to a crawl

Location: Cambridge, United States

MIT civil engineers have for the first time identified what causes the most frequently used building material on earth -- concrete -- to gradually deform, decreasing its durability and shortening the lifespan of infrastructures such as bridges and...

Biomimetic-engineering design can replace spaghetti tangle of nanotubes in thermal material

Location: Cambridge, United States

Nanoelectromechanical systems (NEMS) devices have the potential to revolutionize the world of sensors: motion, chemical, temperature, etc. But taking electromechanical devices from the micro scale down to the nano requires finding a means to...

Biodiesel blend performs as well as ultra-low sulfur fuel

Location: WEST LAFAYETTE, United States

ABSTRACT : Topics : Quantitative Evaluation of an On-Highway Trucking Fleet to Compare #2ULSD and B20 Fuels and Their Impact on Overall Fleet Performance A study was performed on 20 Class-8 trucks paired by make, model, mileage, and drive...

Propelling Underwater Vehicles Using Vortex Ring Generation

Location: California, United States

Abstract : As robots designed to operate underwater become more common, it is useful to look at ways to make them more efficient. Autonomous Underwater Vehicles (AUVs) carry their power source with them, so improving the efficiency of the...

Cutting CO2 emissions from existing coal plants

Location: Cambridge, United States

Professor Ernest Moniz, director of the MIT Energy Initiative (MITEI) unveiled a report on reducing carbon dioxide emissions from existing coal plants. The report is based on the findings of a major MIT symposium on retrofitting coal-fired power...

An expert group for the calculation of fusion in Garching

Location: Max-Planck-Institut für Plasmaphysik (IPP) , Germany

An expert group for high performance calculations was officially established on 20 May 2009 at the Max Planck Institute of Plasma Physics (IPP) in Garching near Munich. The team, named "High-Level-Support-Team" and supported financially by...

Development of a vaccine against schistosomiasis: Bilhvax

Location: DR Inserm North - West, 1 avenue Oscar Lambret - BP 90005, 59008 Lille Cedex - Tel. : 03 20 29 86 70 : 03 20 29 86 70 , Belgium

The Bilhvax vaccine against schistosomiasis, entered its third phase of development, phase of development in clinical research in Senegal to confirm its effectiveness before it is placed on the market. To date, the vaccine was tested among...

The roll of cell mechanical

Location: Marseilles, United States

The life of a cell is not governed only by the biochemistry and genetics. The mechanics also say. A team of physicists from the Institute Fresnel1 in Marseilles, and biologists from the Institute of Developmental Biology of Marseille-Luminy...

Scientists Work To Plug Microorganisms Into The Energy Grid

Location: Oak Ridge, United States

The answer to the looming fuel crisis in the 21st century may be found by thinking small, microscopic in fact. Microscopic organisms from bacteria and cyanobacteria, to fungi and microalgae, are biological factories that are proving to be...

Diode lights offer bright future for low energy

Location: Dresden, Germany

Flat screen television sets. German scientists said Wednesday they had tweaked organic light-emitting diodes (OLEDs) -- the materials used in flat-screen TVs, laptop computer screens and mobile phone displays -- to become flexible,...

Unique Survey Of Ocean Climate May Improve Climate Predictions

Location: Nansen, Norway

A research team from the Nansen Environmental and Remote Sensing Center, and the Bjerknes Centre for Climate Research, both in Bergen, Norway, has studied observed anomalies in ocean climate, and identified the anomalies’ progression...

Entropy and Our Cosmic Telephone Number

Location: Massachusetts, United States

How can the cosmos have the entropy we see today if the temperature was almost exactly the same everywhere after the Big Bang? The answer may lie in our "cosmic telephone number".

When it comes to big question, there...

Bouncing atoms may be the key to the future of gravimetry

Location: Virginia, United States

When studying cold atoms, scientists often use magnetic or optical traps to keep the atoms in place. However, in some cases experimentalists want to study free atoms, avoiding the effects of a trap. "One way to study free atoms,"...

A genetic study reveals the diversity and origins of African populations

Location: Maryland, United States

By analyzing the genetic differences between more than 3 000 people across Africa and from other parts of the world, researchers have shown how the current African populations had evolved from 14 aboriginal groups. The result of their...
