Lightning signature could help reveal the solar system's origins
Every second, lightning flashes some 50 times on Earth. Together these discharges coalesce and get stronger, creating electromagnetic waves circling around Earth, to create a beating pulse between the ground and the lower ionosphere, about 60 miles up in the atmosphere. This electromagnetic signature, known as Schumann Resonance, had only been observed from Earth's surface until, in 2011, scientists discovered they could also detect it using NASA's Vector Electric Field Instrument (VEFI) aboard the U.S. Air Force's Communications/Navigation Outage Forecast System (C/NOFS) satellite.
Ancient volcanic blast provides more evidence of water on early Mars
(Phys.org) -- The atmosphere of Mars is less than 1 percent the density of Earth’s. It’s one of the reasons liquid water covers much of our planet but cannot exist on the Red Planet. As more research points toward the possibility of water on early Mars, scientists have increased their studies on the density of its atmosphere billions of years ago. It’s not an easy task. In fact, it’s very difficult to even determine Earth’s atmospheric pressure from the same time frame.
Paydirt at 8-year-old Mars Rover's 'new landing site'

MicroRNA controls malignancy and resistance of breast cancer cells
Many breast cancer patients are treated with a drug called tamoxifen. The substance blocks the effect of estrogen and thus suppresses the growth signals of this hormone in cancer cells. When resistance to the drug develops, tumor cells change their growth program: They change their behavior and shape, become more mobile and also adopt the ability to invade surrounding tissue. Scientists working with PD (Associate Professor) Dr. Stefan Wiemann of the German Cancer Research Center (DKFZ) have now also observed these changes in tamoxifen resistant breast cancer cells.
Got the munchies? A new pot eatery opens in Ore.

Scientific evidence proves why healers see the 'aura' of people
Researchers in Spain have found that many of the individuals claiming to see the aura of people –traditionally called "healers" or "quacks"– actually present the neuropsychological phenomenon known as "synesthesia" (specifically, "emotional synesthesia"). This might be a scientific explanation of their alleged "virtue". In synesthetes, the brain regions responsible for the processing of each type of sensory stimuli are intensely interconnected. This way, synesthetes can see or taste a sound, feel a taste, or associate people with a particular color.

Different recipes for success in the world of plants
Halle/Saale. In order to prevail against native plants, non-native plant species develop special strategies. These differ in part considerably from the propagation strategies of endemic plant species. Dr. Ingolf Kühn and Dr. Sonja Knapp of the Helmholtz Centre for Environmental Research (UFZ) reached this conclusion in a study published in the current issue of the scientific journal Ecology Letters. "These results are an argument in support of the view that the need to differentiate between native and non-native species in ecological systems remains", says Dr. Ingolf Kühn.
Colors burst into contemporary architecture
White stopped being the official colour of architecture a while ago. New buildings have now been transformed and fragmented and they display movement and innovation thanks to the versatility of colour.
