As many Doctors from the BBC science fiction series "Doctor Who" have so eloquently put it, humanity has an inherent desire to look up toward the sky with dreams of exploring to the ends of the universe. And while our space programs are in many ways in their infancy when it comes to intergalactic exploration, NASA scientists are looking at ways to send manned aircraft farther than we've ever gone before: to Mars.
People make immediate judgments about images they are shown, which could impact on their decisions, even before their brains have had time to consciously process the information, a study of brainwaves led by The University Of Melbourne has found.
Published in PLOS ONE, the study is the first in the world to show that it is possible to predict abstract judgments from brain waves, even though people were not conscious of making such judgments. The study also increases our understanding of impulsive behaviors and how to regulate it.
Mars has become the destination of choice for ambitious space agencies and nations, and now India is among that group. After a successful maneuver, the Mars Orbiter Mission (MOM) has entered an orbit about 420 km above the surface of Mars (MOM is informally called Mangalyaan, which is Hindi for Mars vehicle). It will soon begin to photograph the planet’s surface and analyze the atmospheric composition.
JENNY BOURBEAU is frustrated. For the last 10 months, the Massachusetts mother has been expressing breast milk for her young son. Like many mothers, she needed to use a pump but found the experience impersonal and difficult.
"I spent a lot of time with the pump and the process, thinking about how much it sucks and how it could be better and wondering why it isn't yet," she says.
Via debuted a rugged fanless low-power Android mini-PC based on Via’s dual-core Cortex-A9 Elite E1000 SoC, and offering mini-PCIe, mSATA, HDMI, and GbE I/O.
In the hearts of some massive galaxies lie strange objects known as quasars. These mysterious objects were named for their apparent similarity to stars (quasar is short for ‘quasi-stellar radio source’), but they're now understood to be the light from rapidly accreting, supermassive black holes. In addition to their prodigious light output, they often emit jets of charged particles from their poles at close to the speed of light.
Continued concerns about global warming have boosted work on alternative fuel sources that reduce emissions. Hydrogen is an appealing, clean-burning fuel. Currently, most hydrogen comes from the processing of fossil fuels, which produces carbon dioxide as a byproduct. However, the electrolysis of water produces hydrogen without the release of greenhouse gases—provided the electricity used in the process comes from renewable energy.
New light has been shed on solar power generation using devices made with polymers, thanks to a collaboration between scientists in the University of Chicago's chemistry department, the Institute for Molecular Engineering, and Argonne National Laboratory.
The so-called central dogma of molecular biology—that DNA makes RNA which makes protein—has long provided a simplified explanation for how genetic information is deciphered and translated in living organisms.
