Who would’ve known human waste could be used to propel spacecraft from the moon back to Earth? Researchers responded to the call from NASA and came up with a process to convert waste to methane and propel spacecraft to Earth.
Nanoporous metals — foam-like materials that have some degree of air vacuum in their structure — have a wide range of applications because of their superior qualities.
A commonly prescribed muscle relaxant may be an effective treatment for a rare but devastating form of diabetes, researchers report. The drug, dantrolene, prevents the destruction of insulin-producing beta cells in animal models of Wolfram syndrome and in cells taken … Continue reading
Climate change could lengthen the growing season, make soil drier and decrease winter snowpack in the Lake Michigan Basin by the turn of the century, among other hydrological effects.
Although hummingbirds are much larger and stir up the air more violently as they move, the way that they fly is more closely related to flying insects than it is to other birds. Now, the most detailed, three-dimensional aerodynamic simulation … Continue reading
Physicians from 60 sites treated 161 heart attack patients with their own bone marrow cells, selected for their healing potential and then reinjected into the heart, in an effort to improve the heart’s recovery. Their conclusion? Patients who receive more … Continue reading
New research raises concern about potential long-term harmful impact of ‘antiretroviral therapy’ on in-utero infants whose mothers are HIV-positive, but who are not infected with HIV themselves. The study shows that while the HIV medications have been successful in helping … Continue reading
A new device contains a form of vitamin A that controls inflammatory responses, preventing scar tissue formation and promoting wound healing. The soft, porous, and thin elastic material contains an acid form of vitamin A, called a retinoid, which is … Continue reading
Scientists developed a new method which allows to estimate the magnetic field of a distant exoplanet, i.e., a planet, which is located outside the Solar system and orbits a different star. Moreover, they managed to estimate the value of the … Continue reading
Scientists have completed an exhaustive description of the mouse’s functional genome elements and their comparison with the human genome. Comparing humans and mice enables us to better understand mammalian biology and evolution, as well as contributing new information on the … Continue reading
In the Northern Hemisphere, there’s a strong seasonal cycle of vegetation. Each year in the Northern Hemisphere, levels of atmospheric carbon dioxide drop in the summer as plants “inhale,” then climb again as they exhale after the growing season. During … Continue reading
In the 1970s, ecologists published results from one of the first whole-forest ecosystem studies ever conducted. Scientists reported that salamanders represent one of the largest sources of biomass, or food, of all vertebrates in the forest. Now, using new techniques, … Continue reading
Images from NASA’s Dawn Mission have been used to create a series of high-resolution geological maps of the large asteroid Vesta, revealing the variety of surface features in unprecedented detail.
Scientists have created a graphene/nanotube cathode that may make cheap, flexible dye-sensitized solar cells more practical.
Researchers have engineered a nanowire system that could pave the way for photonic computing, combining two light waves to produce a third with a different frequency and using an optical cavity to amplify the intensity of the output to a … Continue reading
