In a talk at the Kennedy School on Tuesday, physicist Amory Lovins outlined a path to a clean-energy future in the United States.
A portable device can detect the presence of certain types of cancer in people's breath. Tested on patients, the new device was developed in part by EPFL researchers as part of an international collaboration.
The step forward follows research by the Univs. of Warwick and Cambridge and the unexpected discovery of a previously unknown arrangement of molecules in plant cell walls. The researchers investigated the polymer xylan, which comprises a third of wood matter.
Researchers at The Univ. of Manchester have made a significant breakthrough in the development of synthetic pathways that will enable renewable biosynthesis of the gas propane. This research is part of a program of work aimed at developing the next generation of biofuels.
With rising populations and changing climate conditions, the need for resilient and reliable crops has never been greater. Nitrogen, an essential element for plant growth, is often woefully absent in heavily farmed land. Earth’s atmosphere offers an overabundance of nitrogen, but how can it be safely and sustainably transferred into the soil? Nitrogen-eating bacteria may be the answer.
An eruption of lithium at the tip of a battery's electrode, cracks in the electrode's body and a coat forming on the electrode's surface reveal how recharging a battery many times leads to its demise. Using a powerful microscope to watch multiple cycles of charging and discharging under real battery conditions, researchers have gained insight into the chemistry that clogs rechargeable lithium batteries.
When black holes tango, one massive partner spins head over heels (or in this case heels over head) until the merger is complete, according to researchers at Rochester Institute of Technology. This spin dynamic may affect the growth of black holes surrounded by accretion disks and alter galactic and supermassive binary black holes, leading to observational effects.
Our world is full of patterns, from the twist of a DNA molecule to the spiral of the Milky Way. New research from Carnegie Mellon Univ. chemists has revealed that tiny, synthetic gold nanoparticles exhibit some of nature's most intricate patterns. Unveiling the kaleidoscope of these patterns was a Herculean task, and it marks the first time that a nanoparticle of this size has been crystallized and its structure mapped out atom by atom.
While no one yet knows what's needed to build a habitable planet, it's clear that the interplay between the sun and Earth is crucial for making our planet livable: a balance between a sun that provides energy and a planet that can protect itself from the harshest solar emissions. Our sun steadily emits light, energy and a constant flow of particles called the solar wind that bathes the planets as it travels out into space.
Researchers at Chalmers Univ. of Technology have discovered that large area graphene is able to preserve electron spin over an extended period, and communicate it over greater distances than had previously been known. This has opened the door for the development of spintronics, with an aim to manufacturing faster and more energy-efficient memory and processors in computers.
Scientists have made a discovery that could dramatically improve the efficiency of batteries and fuel cells. The research involves improving the transport of oxygen ions, a key component in converting chemical reactions into electricity. The team studied a well-known material, gadolinium doped ceria, which transports oxygen ions and is currently in use as a solid-oxide fuel cell electrolyte.
Supercritical Fluid Technologies presents a line of stirred reactors for high-pressure chemistry. The HPR-Series reactors have been designed for researchers interested in performing pressurized chemical reactions in their laboratories. These reactors are suitable for a range of lab and research-scale applications including, but not limited to, high-pressure chemical synthesis and process development.
Carbon nanotubes (CNTs) are microscopic tubular structures that engineers “grow” through a process conducted in a high-temperature furnace. The forces that create the CNT structures known as “forests” often are unpredictable and are mostly left to chance. Now, a Univ. of Missouri researcher has developed a way to predict how these complicated structures are formed.
A new device developed by Univ. of California, Los Angeles, engineers and doctors may eventually help scientists study the development of disease, enable them to capture improved images of the inside of cells and lead to other improvements in medical and biological research.
Lysosomes are the garbage disposals of animal cells. As the resources are limited in cells, organic materials are broken down and recycled a lot; and that’s what lysosomes do. Detecting problems with lysosomes is the focus of a new set of fluorescent probes developed by researchers at Michigan Technological Univ.
