Inspired by a booming economy and new spending power, the people of China want the advantages that their Western counterparts have: more living space, more comfort and more amenities. Studies by MIT researchers working with colleagues from Chinese universities and development companies suggest that those dreams can be fulfilled without necessarily adopting the energy-intensive practices of the West.
Because of Chinas rapid economic growth, energy consumption is also rising sharply. By 2020, energy consumed for residential and commercial bulidings could rise to fully a third of the energy use by the nation of 1.3 billion people. Sustainable, energy-efficient building design has thus become very important. Researchers in MITs Building Technology Program and their Chinese collaborators have shown that applying some of Chinas traditional approaches and other simple techniques to modern building designs can yield substantial benefits.
For example, researchers demonstrated that a group of energy-efficient low-rise buildings could provide the same living conditions as energy-consuming high-rise structures. The low-rise buildings were designed and oriented to catch the suns heat in winter and the prevailing breezes in summer. They also provide occupants a closer connection with outside communal green spaces.

Species Richness – a false friend? Scientists want to improve biodiversity assessments

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
