Innovation is improbable without proper funding, which is why R&D Magazine and Battelle Memorial Institute annually project how political developments and economic conditions around the globe will affect R&D support in the coming year. Now available, the 2014 R&D Magazine/Battelle Global R&D Funding Forecast offers a comprehensive analysis of the state of industrial research worldwide.

An atmospheric peculiarity the Earth shares with Jupiter, Saturn, Uranus and Neptune is likely common to billions of planets, Univ. of Washington astronomers have found, and knowing that may help in the search for potentially habitable worlds. The paper uses basic physics to show why this happens, and suggests that tropopauses are probably common to billions of thick-atmosphere planets and moons throughout the galaxy.
A unique solar panel design made with a new ceramic material points the way to potentially providing sustainable power cheaper, more efficiently, and requiring less manufacturing time. It also reaches a four-decade-old goal of discovering a bulk photovoltaic material that can harness energy from visible and infrared light, not just ultraviolet light.
Rice Univ. bioengineers have developed a hydrogel scaffold for craniofacial bone tissue regeneration that starts as a liquid, solidifies into a gel in the body and liquefies again for removal. The material developed in a Rice laboratory is a soluble liquid at room temperature that can be injected to the point of need. At body temperature, it turns into a gel to help direct the formation of new bone to replace that damaged by injury.
Jupiter’s moon Europa features an intricate network of cracks in its icy surface. This unusual pattern is particularly pronounced around the equator. Scientists performing modeling studies on the potential marine currents below this ice layer have discovered that, near Europa’s equator, warmer water rises from deep within the moon.
There are examples of art imitating nature all around us, from Monet to Chihuly, but when physicist Latika Menon peered under the electron microscope last fall, she discovered the exact opposite in gallium nitride nanowires that bore an uncanny resemblance to artistic pots found in her native India. Menon has begun to control these shapes, which will make the nanowires significantly more promising for use in advanced devices.
British Prime Minister David Cameron says he hopes to kick-start an international effort to find a cure or effective treatment for dementia by 2025. At a one-day summit on dementia hosted by the U.K., Cameron declared that discovering a cure or treatment for dementia is "within our grasp." The Group of Eight health and science ministers signed a declaration agreeing to identify "a cure or disease-modifying therapy for dementia" by 2025.
Figuring that if some is good, more must be better, researchers have been trying to pack more graphene, a supermaterial, into structural composites. Collaborative research led by Univ. of Nebraska-Lincoln materials engineers discovered that, in this case, less is more. The team learned that using a small amount of graphene oxide as a template improves carbon nanomaterials which, in turn, promises to improve composite materials.
Stanford Univ. scientists may have solved the mystery of what drives a type of earthquake that occurs deep within the Earth and accounts for one in four quakes worldwide. Known as intermediate-depth earthquakes, these temblors originate farther down inside the Earth than shallow earthquakes, which take place in the uppermost layer of the Earth's surface, called the crust.
JPK Instruments has released its next generation of NanoWizard AFM systems, providing fast scanning and super-resolution on an inverted microscope. The fast-scanning NanoWizard ULTRA Speed AFM is important to users as it enables the tracking of changes in samples in real time, whether the sample be imaged in air or liquid.
JEOL Ltd. has announced a joint initiative between JEOL and Gatan that brings the power of Serial Block Face imaging to the JEOL family of scanning electron microscopes. Researchers are now able to image 3-D structures of biological and materials samples at ultra-high resolution using the JEOL JSM-7100F field emission scanning electron microscope with an integrated Gatan 3View Serial Block Face imaging system.
Although researchers have determined the ages of rocks from other planetary bodies, the actual experiments have been done on Earth. Now, for the first time, researchers have successfully determined the age of a Martian rock with experiments performed on Mars. The work could not only help in understanding the geologic history of Mars but also aid in the search for evidence of ancient life on the planet.
Blood clots play an unexpected role in protecting the body from the deadly effects of bacteria by absorbing bacterial toxins, researchers have found. Even with modern antibiotics, septic shock from bacterial infections afflicts about 300,000 people a year in the U.S., with a mortality rate of 30 to 50%. Septic shock is caused by Gram-negative bacteria, which release a toxin called lipopolysaccharide or endotoxin.
Solar cells made with low-cost, nontoxic quantum dots can achieve unprecedented longevity and efficiency, according to a study by Los Alamos National Laboratory and Sharp Corp. The reported solar cells are based on nontoxic quantum dots. These dots are based on copper indium selenide sulfide and are rigorously optimized to reduce charge-carrier losses from surface defects and to provide the most complete coverage of the solar spectrum.
By applying pressure to a semiconductor, researchers have been able to transform a semiconductor into a “topological insulator” (TI), an intriguing state of matter in which a material’s interior is insulating but its surfaces or edges are conducting with unique electrical properties. This is the first time that researchers have used pressure to gradually “tune” a material into the TI state.
For some microbes, the motto for growth is not so much “every cell for itself,” but rather, “all for one and one for all.” Researchers have found that cells in a bacterial colony grow in a way that benefits the community as a whole. That is, while an individual cell may divide in the presence of plentiful resources to benefit itself, when a cell is a member of a larger colony, it may choose instead to grow in a more cooperative fashion.
