Natural Gas Natural gas futures were among the quarter's key decliners -LRB--7.5 %, to US$ 2.73 per million British thermal units) as production growth outweighed
seasonal consumption and higher exports of the fuel.1 Spot prices
saw an even larger drop of 20.6 % (to US$ 2.81) as the support of December's weather - related demand spikes faded and a more normal winter
pattern developed.1 Natural gas generally took its downward price cues from elevated US production and growth in the natural gas - focused rig count, which increased from 179 to 194 in March alone.2 Despite the price drop, traders remained optimistic given surging US shale - gas exports and a supply deficit that was 20 % larger than the five - year average at March - end, the biggest in four years.3 Moreover, total natural gas inventories of 1.38 trillion cubic feet were nearly 33 % below their year - ago level.3 Meanwhile, the market appeared focused on an anticipated production surge (2018 is projected to be a record growth year for gas supplies) and may have overlooked intensifying demand as US exports increasingly helped drain supplies.

pattern of attachment of two genetically engineered emerging H7 viruses (containing the hemagglutinin (HA) of either influenza virus A / Shanghai / 1 / 13 or A / Anhui / 1 / 13) to fixed human respiratory tract tissues and compared the findings to attachment
patterns seen with human influenza viruses with high transmissibility but low virulence (
seasonal H3N2 and pandemic H1N1) and highly pathogenic avian influenza (HPAI) viruses with low transmissibility and high virulence (H5N1 and H7N7).

For the entire Northern Hemisphere, there is evidence of an increase in both storm frequency and intensity during the cold season since 1950,1 with storm tracks having shifted slightly towards the poles.2, 3 Extremely heavy snowstorms increased in number during the last century in northern and eastern parts of the United States, but have been less frequent since 2000.11,15 Total
seasonal snowfall has generally decreased in southern and some western areas, 16 increased in the northern Great Plains and Great Lakes region, 16,17 and not changed in other areas, such as the Sierra Nevada, although snow is melting earlier in the year and more precipitation is falling as rain versus snow.18 Very snowy winters have generally been decreasing in frequency in most regions over the last 10 to 20 years, although the Northeast has been
seeing a normal number of such winters.19 Heavier - than - normal snowfalls recently observed in the Midwest and Northeast U.S. in some years, with little snow in other years, are consistent with indications of increased blocking (a large scale pressure
pattern with little or no movement) of the wintertime circulation of the Northern Hemisphere.5 However, conclusions about trends in blocking have been found to depend on the method of analysis, 6 so the assessment and attribution of trends in blocking remains an active research area.
