"Philae's observations aren't just skin-deep. Using its Comet Nucleus Sounding Experiment by Radiowave Transmission (CONSERT) instrument, the lander also sounded out the comet's interior. This instrument picks up long-wavelength signals beamed through 67P by the orbiting Rosetta mothership.
CONSERT data suggest that the "head" of the rubber-duck-shaped comet is internally homogeneous on the scale of a few tens of meters, and extremely porous, with open space making up 75 to 85 percent of its volume, researchers said."

"Majority Leader Kevin McCarthy said Monday that the House will not consider the Senate version of a long-term, must-pass highway bill, setting up an apparent impasse as Congress faces a Friday deadline. ...Great.
“We’re not taking up the Senate bill,” McCarthy, R-Calif., told reporters. Pressed on whether he was ruling it out, he said, “Yes.” "
The House has already passed its own four-and-a-half month highway bill. But the Highway Trust Fund — which provides federal funding for transportation projects across the country — will expire on its deadline of midnight July 31 unless the two chambers can agree on a version, or pass a stop-gap measure before then.
McCarthy said the House will leave as scheduled on Thursday for a month-long recess, leaving McConnell to decide whether to forfeit his push for a longer-term bill in order to prevent the trust fund from expiring.
"Hillary Clinton has signaled that she hopes to run for president in part by painting the GOP-controlled Congress — and, by extension, the Republican Party — as a divisive, destructive, hidebound, reactionary force. As the Post recently put it, Clinton has accused Congressional Republicans “of waging a war on women, playing politics with a black nominee, shortchanging students, endangering the economic recovery and trying to yank health-care coverage for 16 million Americans.” "Well, not funding the highway trust fund would definitely endanger the economic recovery. So yes, she should make these Republican travesties of governing a campaign issue.

This cape is at the tip of a blunt, mountainous peninsula and marks the southern side of the entrance to Ishikari Wan and the important port of Otaru. The point of the cape is a knife-like volcanic ridge similar to the famous Pointe du Raz in Brittany. The scenery is spectacular, and the cape is a popular tourist destination.
"I'm going to hazard a speculation here. The spots are ice. (Wow, major speculation effort.) What I'm expecting is that there is going to be some unique asteroidal geological process in that location that keeps the ice "fresh" and reflective, i.e., not covered by regolith -- another word for dust.
What that process might be -- I have no clue. But I don't think that they are vapor, like a gas jet, because they are too immobile and there has been not a mention of any kind of Cerean atmosphere with a little tenuous water vapor."Well, surprise, surprise, surprise -- I was sort of right by being wrong. Two articles (there are more, but here's two):
" "If you look at a glancing angle, you can see what seems to be haze, and it comes back in a regular pattern," Dawn principal investigator Christopher Russell, of UCLA, said during a presentation Tuesday (July 21) at the second annual NASA Exploration Science Forum, which took place at the agency's Ames Research Center in Moffett Field, California."OK, so they probably aren't vapor, but because they might possibly be ice, they appear to be releasing vapor -- water vapor, of course.
"During June, the average temperature across global land and ocean surfaces was 1.58°F (0.88°C) above the 20th century average. This was the highest for June in the 1880–2015 record, surpassing the previous record set last year in 2014 by 0.22°F (0.12°C)."

"How big a failure have Walkernomics been? Just look next door at Democratic Gov. Mark Dayton’s Minnesota, which leads Wisconsin in almost every economic indicator.
In Minnesota, Dayton turned a $5 billion budget deficit into an over $1 billion budget surplus in just one term. By requiring the wealthiest earners to pay their fair share, Minnesota is now in a position to invest more resources into the state’s schools and infrastructure.So, Wisconsin's economy with Walker at the helm has been adrift. Next up: his horrendous positions on climate change and the environment.
In Wisconsin, Walker was unable to take his state out of the red and faced a $2 billion budget deficit. Walker made the decision to cut taxes for millionaires and billionaires, while slashing education funding and refusing to make investments that would benefit middle class families and Wisconsin’s financial wellbeing.
In Minnesota, Dayton has moved forward Democratic policies like increasing the minimum wage, expanding Medicaid, and investing in the middle class, and now we are seen as one of the most business friendly states in the country. Just this year, Forbes ranked Minnesota as the 9th best state for business and careers, 7th in economic climate and 2nd in quality of life. On top of all that, CNBC just ranked Minnesota the country’s top state for business in 2015."
"Buried within the [Wisconsin biennial] budget are 135 non-budget policy items — a toxic cocktail of attacks on public education, democracy, environmental protections and labor rights."Not good at all.
"The attack on the Milwaukee Public Schools (MPS) is in the context of a frontal assault on public education across the state. The budget cuts $250 million from the University of Wisconsin system, holds overall K-12 funding flat in the first year with modest increases in the second (which, given inflation, means cuts)."
"Elected school boards and lack of choices are not the problem with our schools. Milwaukee arguably has more publicly funded school options than any urban system in the country, from citywide and neighborhood-based public schools, to MPS charter schools, to city-controlled charter schools, to charters run by the University of Wisconsin-Milwaukee, to private voucher schools, to open enrollment that includes suburban districts. The rhetoric around governance is a smokescreen to get rid of democratically elected school boards and publicly controlled schools. Yes, democracy can be messy, but the alternative is worse. If we decide to abandon every democratic institution that is not up to our hopes and dreams, why not get rid of the U.S. Congress? Or the Wisconsin Legislature?"
"Recent (station established 1885). Active; focal plane 16 m (52 ft); red flash every 5 s. 15 m (50 ft) strongly-tapered concrete pillar, with a gallery but no lantern. Tower painted white with a broad red band at the base; gallery red."It also has this:

"McConnell earlier this year placed himself on the appropriations subcommittee with authority over the EPA, in an effort to exercise more power over the agency.He calls it "overreach". I and many others concerned about the environment and its healthy functioning call it "doing the job it was created for".
“As a member of this subcommittee, I was able to secure a number of policy provisions in this EPA funding bill that passed out of committee, provisions that seek to scale back the overreach of the EPA,” he said."
A. "Fear of radiation is an obvious candidate. Dr. Spencer Weart traced how the fear of nuclear is much more complicated and much older than nuclear weapons or nuclear energy, starting from the beginning of modern science and technological societies in the late 1800s. While we presently think of radiation as a subset of the nuclear age, it was the concept of radiation that came first."
B. "Later, with the dropping of the first atomic bomb on Japan, nuclear came to be associated with the ultimate end member of this dark side to technology. ... That the many firebombing campaigns during World War II released over 10 times more energy than Hiroshima and Nagasaki combined is not relevant to this meme. The idea that so small an amount of mass could release so large an amount of energy captivated the mind and enshrined nuclear as the ultimate power, and thus, the ultimate seduction in these mythologies to those who would wield it."But here's where I thought it got really good -- and made sense.
"Our first trials with nuclear energy over the last 50 years proved that nuclear is the safest and most efficient of all energy sources, from both the human health and environmental perspectives. To produce a trillion killowatt-hours of electricity, nuclear takes less land, uses less steel and concrete, kills fewer people and has less harmful emissions than any other energy source, including wind and solar.Right. That makes GREAT sense.
But this experience has not yet infused the meme of global energy sufficiently to move nuclear power to the forefront of the energy sources we need to embrace as a species in order to save the planet. Renewables, new generation nuclear, low carbon sources, efficiency and environmental protection all need to be incorporated into the meme of a safe, reliable and sustainable energy future."
"The rover is working about half a football field's length away from entering the western end of "Marathon Valley," a notch in the raised rim of Endeavour Crater, which is about 14 miles (22 kilometers) in diameter. Opportunity landed on Mars in 2004 and has been studying the rim of Endeavour since 2011.
Engineers and scientists operating Opportunity have chosen Marathon Valley as the location for the solar-powered rover to spend several months, starting in August, to take advantage of a sun-facing slope loaded with potential science targets.
Marathon Valley stretches about three football fields long, aligned generally east-west. Observations of the valley using the Compact Reconnaissance Imaging Spectrometer for Mars aboard NASA's Mars Reconnaissance Orbiter have detected exposures of clay minerals holding evidence about ancient wet environmental conditions. Researchers plan to use Opportunity to investigate relationships among these clay-bearing deposits."
"And what marvels Dawn has beheld! How can you not be mesmerized by the luminous allure of the famous bright spots? They are not, in fact, a source of light, but for a reason that remains elusive, the ground there reflects much more sunlight than elsewhere. Still, it is easy to imagine them as radiating a light all their own, summoning space travelers from afar, beckoning the curious and the bold to venture closer in return for an attractive reward."
"In addition to evidence of aging and renewal, some powerful internal forces have uplifted mountains. One particularly striking structure is a steep cone that juts three miles (five kilometers) high in an otherwise relatively smooth area, looking to an untrained (but transfixed) eye like a volcanic cone, a familiar sight on your home planet (or, at least, on mine). No other isolated, prominent protuberance has been spotted on Ceres."
