The key to better cell phones and other rechargeable electronics may be in tiny "sandwiches" made of nanosheets, according to mechanical engineering research from Kansas State Univ. The research team are improving rechargeable lithium-ion batteries. The team has focused on the lithium cycling of molybdenum disulfide, or MoS2, sheets, which Singh describes as a "sandwich" of one molybdenum atom between two sulfur atoms.

Immediately following the passage of the Energy Independence and Security Act (EISA) of 2007, much research interest focused on the development of bio-based renewable energy sources (biofuels). EISA mandated increased production and use of biofuels for the long term. There also appeared to be substantial long-term government support for the implementation of a biofuel-based industry.
The design of laboratories for sustainable construction and operation has become a major driver in the A/E/C industry over the past 10 to 15 years. These days, most lab clients are looking for sustainable design approaches at a minimum—and third-party certification, such as LEED, in many cases.
In the past decade, the expansion of research focus areas in engineering has undergone a transformation. The demands of engineering labs present challenges for institutions because most occupied spaces were conceived during an era with radically different needs and required services.
By combining two highly innovative experimental techniques, scientists at the Univ. of Illinois at Urbana-Champaign have for the first time simultaneously observed the structure and the correlated function of specific proteins critical in the repair of DNA, providing definitive answers to some highly debated questions, and opening up new avenues of inquiry and exciting new possibilities for biological engineering.
The race is on around the world as scientists strive to develop a new generation of batteries that can perform beyond the limits of the current lithium-ion based battery. Researchers at the Univ. of Illinois at Chicago have taken a significant step toward the development of a battery that could outperform the lithium-ion technology used in electric cars such as the Chevy Volt.
3D printing has been used to make everything from cars to medical implants. Now, Univ. of Washington ecologists are using the technology to make artificial flowers, which they say could revolutionize our understanding of plant-pollinator interactions.
From above, five years after the BP well explosion, the Gulf of Mexico looks clean, green and whole again, teeming with life: a testament to the resilience of nature. But there's more than surface shimmering blue and emerald to the aftermath of the Deepwater Horizon spill. And it's not as pretty a picture, nor is it as clear.
Research on a modified protein around which DNA is wrapped sheds light on how gene regulation is linked to aging and longevity in nematodes, fruit flies and possibly humans. The research has implications for how gene expression is regulated, and could offer a new drug target for age-related diseases.
An international team of scientists have put forward a blueprint for a purely space-based system to solve the growing problem of space debris. The proposal combines a super-wide field-of-view telescope and a recently developed high-efficiency laser system, the CAN laser that will be used to track space debris and remove it from orbit.
Neutrinos are a type of particle that pass through just about everything in their path from even the most distant regions of the universe. The Earth is constantly bombarded by billions of neutrinos, which zip right through everything. Only very rarely do they react with matter, but the giant IceCube experiment at the South Pole can detect when there is a collision between neutrinos and atoms in the ice using a network of detectors.
A concentrated extract of maple syrup makes disease-causing bacteria more susceptible to antibiotics, according to laboratory experiments by researchers at McGill Univ. The findings suggest that combining maple syrup extract with common antibiotics could increase the microbes’ susceptibility, leading to lower antibiotic usage.
China has become the world’s largest exporter, leading to the country’s rapid economic development, and notorious pollution that’s harmful to human health. For the first time, scientists have estimated this trend’s health cost. They report in Environmental Science & Technology that in 2007, export-related emissions in China led to almost 160,000 deaths.
How does climate change affect the occurrence and distribution of species? This is a key question in the climate debate, and one that is hard to answer without information about natural variation in species abundance. Now researchers from Uppsala Univ. can, for the first time, give us a detailed picture of natural variation through study published in Current Biology.
Scientists at The Univ. of Manchester have discovered a way to make trees grow bigger and faster, which could increase supplies of renewable resources and help trees cope with the effects of climate change. In the study, published in Current Biology, the team successfully manipulated two genes in poplar trees in order to make them grow larger and more quickly than usual.
Zinc deficiency, long associated with numerous diseases like certain cancers, can lead to activation of the Hedgehog signaling pathway, a biomolecular pathway that plays essential roles in developing organisms and in diseases, according to new research at Rensselaer Polytechnic Institute.
