Rep. James Clyburn (S.C.) — Clyburn is the highest-ranking Democratic leader to say he’ll skip the speech.
After an exhaustive analysis of data obtained during 605 Martian days, Nasa'sCuriosity rover has confirmed the presence of methane on Mars environment which may hint that life once existed on the Red Planet.
The tunable laser spectrometer in the SAM (Sample Analysis at Mars) instrument of the Curiosity rover has unequivocally detected an episodic increase in the concentration of methane in Mars' atmosphere.
This puts an end to the long controversy on the presence of methane in Mars, which started over a decade ago when this gas was first detected with telescopes from the Earth, the authors from the Mars Science Laboratory (MSL) reported.
Since methane can be the product of biological activity - practically all the existing methane in the Earth's atmosphere originates in this way - this has created great expectations that Martian methane could also be of a similar origin.
"It is a finding that puts paid to the question of the presence of methane in the Martian atmosphere but it does pose some other more complex and far-reaching questions, such as the nature of its sources," said study co-author Francisco Javier Martin-Torres from the Andalusian Institute of Earth Sciences (CSIC-UGR) at the University of Granada, Spain.
"The sources, we believe, must lie in one or two additional sources that were not originally contemplated in the models used so far. Among these sources, we must not rule out biological methanogenesis," he added.
According to some current models, if there really existed methane in Mars, it would remain there for an average 300 years and during this period, it would be homogeneously distributed across the atmosphere.
SAM has been detecting basal levels of methane concentration and has confirmed an event of episodic increase of up to 10 times this value during a period of 60 Martian days.
The new data are based on observations during almost one Martian year (almost two Earth years), included in the initial prediction for the duration of the mission (nominal mission), during which Curiosity has surveyed about 8 kms in the basin of the Gale crater.
NSA's bulk collection of American data gets approved again: a year after the president promised to end the program.
The program must be reapproved every 90 days to continue. The recent approval went a few days past its mark to line up with June 1, 2015 as the end of the new 90-day cycle. June 1 is when the program, under Section 215 of the PATRIOT Act, must be reauthorized or reformed by Congress, according to its written parameters.
If no action is taken by Congress, Section 215 will expire and bulk collection under it will end. However, many experts have pointed out how bulk collection programs could continue regardless of Section 215. Many of them have recommended a robust reform of the program, rather than just letting it expire.
Jonathan Nimerfroh is a photographer and surfer who says he's obsessed with the ocean. He happened to be in the right place at the right time recently while walking along the coast of Nantucket. He happened to capture some waves that were nearly frozen and he managed to snap a few unique pictures. The temperature on this day was 19 F and -7 C which caused the waves to freeze but not completely.

To justify its actions, the FCC had to resort to misleading distortions that essentially asserted “the Internet is so horribly broken that only the government can fix it.” And “you can trust unelected Washington bureaucrats to do a better job of running the highly complex Net than engineers, entrepreneurs and consumers.”
The ultimate result of more government encroachment will be something akin to the sagging European Internet market, where investment in broadband infrastructure is only one-fourth of America’s due to heavy-handed regulations. Even worse, this new power grab could trigger expanded intergovernmental powers over the Web through existing telecom treaties, jeopardizing Internet freedom.
