The researchers studied the brains of rodents for the short-term and long-term effects of eating a high-fat diet. After giving groups of 6 to 10 rats and mice a high-fat diet for periods from one day… read more
A high-performance 3D microbattery that could be integrated into microchips at production volumes has been developed by University of Illinois at Urbana-Champaign researchers.
Miniaturizing a battery to fit in a microchip is a major challenge, but it would be important for providing power to microscale devices such as actuators, distributed wireless sensors and transmitters, and portable and implantable medical devices, explained Paul Braun, a professor of … read more

The diode’s rectification ratio (ratio of forward to reverse current at fixed voltage) is in excess of 200, “a record for single-molecule devices,” says Jeff Neaton, Director of the Molecular Foundry, a senior faculty scientist… read more
Researchers at MIT and their collaborators have developed a high-performance and possibly less expensive way to convert solar heat into electricity, using flat-panel solar power combined with hot water systems.
Their system produces power with an efficiency roughly eight times higher than ever previously reported for a solar thermoelectric device that produces electricity from solar heat. It does so by generating and harnessing a temperature difference of… read more

Engineers at Stanford University have developed a prototype single-fiber endoscope that is as thin as a human hair, with a resolution four times better than previous devices of similar design.
The “micro-endoscope” is a significant step forward in high-resolution, minimally invasive bioimaging, with potential applications in research and clinical practice. Micro-endoscopy could enable new methods in diverse fields ranging from study of the brain to early cancer… read more

The technique is a major advancement toward the ultimate goal of imaging biological processes in action at the atomic level.
The technique uses two silicon-nitride microchips with windows etched in their centers and pressing them together until only… read more

As we approach the limits of miniaturization of silicon semiconductors, at universities and corporate laboratories around the world, researchers are trying to develop the next generation of chip-making technologies.
Stanford University researchers are making prototypes of a new kind of molecular-scale semiconductor nanocircuit called a carbon nanotube field effect transistor (CNFET) that is far smaller and uses far less power than today’s most advanced silicon-based computer circuits. It may… read more

Several studies in the last year have found that missing or extra pieces of DNA in the 1q21.1 region put the bearer at risk for a surprisingly broad range of psychiatric and neurological disorders, including autism, schizophrenia, and mental retardation.
The discovery that one piece of DNA can lead to such diverse outcomes is opening new avenues in the study of disease.

You can build a holographic microscope for $250 (for parts), MIT Technology Review Physics arXiv Blog reports.
Holographic microscopes record the 3D shape of tiny objects such as cells in high resolution, unlike traditional microscopes, which have a tiny field of view and shallow depth of field.
With a holographic microscope, you make a hologram of the sample: split a laser beam in two, use one as… read more

A thermal regulator that uses neural networks to learn about your house as the seasons change has been developed by a spinoff from École Polytechnique Fédérale de Lausanne (EPFL) and the Swiss Center for Electronics and Microtechnology (CSEM).
Most home thermal regulators only react to a single parameter — the outside temperature — in regulating their output.

In a new open-access report in the NIH journal Environmental Health Perspectives, 47 scientists, health practitioners, and children’s health advocates have made a consensus statement in “Project TENDR: Targeting Environmental Neuro-Developmental Risks“ — endorsed by nine medical organizations — and issued a call to action for renewed attention to the growing evidence that many common and widely available chemicals endanger neurodevelopment in fetuses and children of all ages.… read more

The first-ever antimicrobial hydrogel that can break apart biofilms and destroy multidrug-resistant superbugs upon contact has been developed by researchers from the Institute of Bioengineering and Nanotechnology (IBN) and IBM Research.
Tests have demonstrated the effectiveness of this novel synthetic material in eliminating various types of bacteria and fungi that are leading causes of microbial infections, and preventing them from developing antibiotic resistance.

Tel Aviv University researchers hope to turn smartphones into powerful hyperspectral sensors that determine precise spectral data for each pixel in an image.
As with the Star Trek tricorder,* the enhanced smartphones would be capable of identifying the chemical components of objects from a distance, based on unique hyperspectral signatures.
The technology combines an optical component and image processing software, according to… read more

The multiple joints of its legs are controlled by a movement algorithm that enables the robot to walk on uneven surfaces (like Boston Dynamics’ Big Dog), avoid obstacles, and climb stairs to get access into areas can’t be reached by wheeled robots (such as some iRobot… read more
