The paper supports arguments Montgomery put forth in a popular book, "Dirt: The Erosion of Civilizations," published earlier this year by the University of California Press. In the book, he linked the demise of history's major civili...Link between sunspots, rain helps predict disease in east Africa

The team hypothesized that the new measured peaks likely originate from mechanical motions of the dimer, which causes enhancement of the electrical cu...Purdue-IU researchers explore new method for early disease diagnosis
...iling. The spectrum is represented by a pattern of peaks corresponding to different frequencies that can be used to identify the molecules like amino acids in biofluids. Each metabolite has a unique pattern of peaks. Researchers use nuclear magnetic resonance to detect hydrogen or carbon atoms to provide...Research finds that circadian rhythms dominate all life functions
...of all genes fall into the same phase or timing of peaks and valleys. Synchronization with the activity of the other genes and genes in different organs is a very important and highly specific part of gene function. In addition, genes can oscillate with different amplitude -- the swing between the highest...Essential tones of music rooted in human speech

The antioxidant vitamins and magnesium used in the study are widely used dietary supplements, not new drugs, and therefore they dont require the extensive safety tests required for new drug...When your brain talks, your muscles don't always listen
...follow the outline of a sinusoidal curve, with its peaks and valleys, on a computer screen. "More force--which is indicated by a corresponding higher firing rate of neurons--is exerted just before you begin the upturn toward one peak and then it eases off again in the downturn toward a valley," Knight no...Research suggests a significant circadian rhythm in swim performance lasting 2-4 minutes

In the highly competitive sports environment, where financial stakes are often high, team managers will find it useful to add the study of physiological concepts such...The last wild hunt -- Deep-sea fisheries scrape bottom of the sea

Satellite navigation (GPS) and military surveillance technology can visualize seamounts where schools of orange roughy, in times of former abundance, resembled lava spilling down the sides of a vol...Bats prey on nocturnally migrating songbirds

This contrasted strikingly with food composition of other European bat species which all feed exclusively on invertebrates! This finding brought about a heated contr...Shedding new light on proteorhodopsin
... "Proteorhodopsin has an absorption spectrum that peaks in the green wavelengths, so the cells swam when they were exposed to green light, but stopped when they were exposed to red light." In the absence of the azide respiratory poison, green light had no effect on the flagellar motors of these proteorh...Scientists map key landmarks in human genome
...s. On a graph, the data displayed as a series of peaks and troughs corresponding to positioned nucleosomes and nucleosome-free regions, respectively. Analysis revealed that promoters of genes that had similar expression status (they were all "off" or "on") had related nucleosome locations. The technique ...Cellular killer also important to memory
... The concentration of unbound, activated caspase-3 peaks about 10 minutes after the birds hear the new songs. Other research has added to the evidence that caspase-3 is essential to memory formation. Caspase-3 inhibitors injected into rat brains interfere with the animals' spatial memory and active avoidan...Researchers find two biomarkers with potential to predict breast cancer spread

Controlling population peaks on the edges of the gypsy moth range may help to slow their invasion into virgin territory, according to a team of researchers. "Slowing the spread of the gypsy moth is a priority in forest management in the U.S.," says Ottar Bjornstad, associate pro...Speak, memory: Research challenges theory of memory storage

This is surprising; Previous studies showed that during deep sleep, when the excitatory cells in the neocortex showed rhythmic activity, excitatory neurons in the hippocampus showed erratic activity. This...RNA map provides first comprehensive understanding of alternative splicing
.... Unexpectedly, this search revealed four discrete peaks where the binding clusters locate. Furthermore, the location of the peaks correlated with Nova's action on regulating whether the alternative exon is spliced in or out.
