How would you know if your water in space were infected with something? Water is easy enough to clean but it requires some precision and current methods only examine water cleanliness after the fact.
University of Utah chemists developed a two-minute water quality monitoring method that just started six months of tests aboard the International Space Station.
The new method involves sampling space station or space shuttle galley water with syringes, forcing the water through a chemical-imbued disk-shaped membrane, and then reading the color of the membrane with a commercially available, handheld color sensor normally used to measure the color and glossiness of automobile paint.
There's been a surprising archaeological discovery at Tel Dor in Israel, a place that was only on the periphery of the Hellenistic world; a gemstone engraved with a portrait of Alexander the Great.
Alexander was probably the first Greek to commission artists to depict his image – as part of a personality cult that was transformed into a propaganda tool. Rulers and dictators have implemented this form of propaganda ever since. The excavations were done by an archaeological team directed by Dr. Ayelet Gilboa of the University of Haifa and Dr. Ilan Sharon of the Hebrew University of Jerusalem.
Over one third of American pre-schoolers live in homes where the television is on most of the time, even if no one's watching, and a new study says the effect of background TV on interactions between parents and young children is definitely negative.
The researchers studied about 50 1-, 2-, and 3-year-olds, each of whom was with one parent, at a university child study center. Half of the one-hour session, parents and children were in a playroom without TV; in the other half-hour, parents chose an adult-directed program to watch , like Jeopardy. The researchers observed how often parents and children talked with each other, how actively involved the parents were in their children's play, and whether parents and children responded to each other's questions and suggestions.
A mystery of evolution is why an extra chromosome can be common across plants and animals yet have such drastically different results. A human with an extra chromosome may have Down syndrome while a cat may just be a male Calico. And plants may not only not have a negative effect, it may be downright beneficial
Contrary to short-term consensus beliefs, El Niño has not been getting stronger because of global warming, says Benjamin Giese, a professor of oceanography at Texas A&M who specializes in ocean modeling, but he found a link between El Niño and the severe flu pandemic 91 years ago.
Coincidence? The 1918 El Niño was apparently one of the strongest of the 20th century but how is it relevant to flu?
Astrid Skreosen worked for many years as an auxiliary nurse in the maternity ward in Skien Hospital and became fed up with the little mats which were supposed to lie under women who were giving birth that were intended to soak up waste products and fluids so she began to look into the possibility of producing a specially modified super-absorbent bed sheet.
After stumbling around in the dark for a while with inventors’ consultants and patent offices, she rang SINTEF (Skandinavias største uavhengige forskningsorganisasjon) Materials and Chemistry and spoke with Per Stenstad.
