A planet made of diamonds may sound lovely, but you wouldn't want to live there. A new study suggests that some stars in the Milky Way could harbor "carbon super-Earths", giant terrestrial planets that contain up to 50% diamond. But if they exist, those planets are likely devoid of life as we know it.
An otherwise nondescript binary star system in the Whirlpool Galaxy has brought astronomers tantalizingly close to their goal of observing a star just before it goes supernova. The study provides the latest result from an Ohio State University galaxy survey underway with the Large Binocular Telescope, located in Arizona.
Dust is dust, right? After identifying 63 unique dust particles from their own laboratory, researchers at Ohio State University can definitively say that not all dust is created equal. Quartz is a common component, but organic matter is also prevalent. The findings and testing method could improve environmental and health-related testing.
To help make communications devices more reliable, Ohio State University researchers have invented a new type of antenna that allows them to place radio devices directly into clothing, using plastic film and metallic thread.
A team of engineering students at The Ohio State University’s (OSU) Center for Automotive Research (CAR) recently began running aerodynamics simulations at the Ohio Supercomputer Center (OSC), one of the first steps in the long and careful process of designing, building, and racing the fourth iteration of their alternative-fuel streamliner.
Ohio State University researchers are leveraging powerful supercomputers to investigate one of the key observational probes of "dark energy," the mysterious energy form that is causing the expansion of the universe to accelerate over time.
Astronomers' research on celestial bodies may have an impact on the human body. Ohio State Univ. astronomers are working with medical physicists and radiation oncologists to develop a potential new radiation treatment—one that is intended to be tougher on tumors, but gentler on healthy tissue.
Researchers are studying some common soil bacteria that "inhale" toxic metals and "exhale" them in a non-toxic form. The bacteria might one day be used to clean up toxic chemicals left over from nuclear weapons production decades ago. Using a unique combination of microscopes, researchers at Ohio State Univ. and their colleagues were able to glimpse how the Shewanella oneidensis bacterium breaks down metal to chemically extract oxygen.
A new study aimed at refining the way scientists measure ice loss in Greenland is providing a "high-definition picture" of climate-caused changes on the island. And the picture isn't pretty. In the last decade, two of the largest three glaciers draining that frozen landscape have lost enough ice that, if melted, could have filled Lake Erie.
Engineers at Ohio State Univ. have invented a new kind of nanoparticle that shines in different colors to tag molecules in biomedical tests. These tiny plastic nanoparticles are stuffed with even tinier bits of electronics called quantum dots. Like little traffic lights, the particles glow brightly in red, yellow, or green, so researchers can easily track molecules under a microscope.
Engineers at Ohio State Univ. have invented a lens that enables microscopic objects to be seen from nine different angles at once to create a 3D image.
Researchers are using a new model to learn more about how toe strength can determine how far people can lean while keeping their balance. The results could help in building robotic body parts that will closely imitate human movement, and might lead to a new generation of advanced prosthetics.
Researchers at Ohio State Univ. (Columbus, Ohio) have developed the High-Temperature Total NOx Sensor. By using a Pt-loaded zeolite as a catalyst filter placed before the sensing element, NOx species in the gas stream are brought to an equilibrium concentration of NO and NO2. The equilibrated NOx is then measured with an yttria-stabilized zirconia-sensing element using a metal oxide-sensing electrode in a potentiometric mode.
The High-Temperature Potentiometric Oxygen Sensor with Internal Reference, developed by teams at Ohio State Univ., Columbus and Argonne National Laboratory, Ill., can withstand temperature up to 1600° C and eliminates the need for costly and bulky high temperature resistant external plumbing for a reference air system.
Airline fire detectors have historically produced as high as a 200 to 1 rate of false alarms. For this reason, researchers from NASA Glenn Research Center, Cleveland, Ohio, in a joint effort with Makel Engineering, Inc., Chico, Calif., Case Western Reserve Univ., Cleveland, Ohio, and Ohio State Univ., Columbus, have developed the Multi-Parameter, MicroSensor-Based Low False Alarm Fire Detection System (MMFDS).
