Nancy Pelosi on Democratic Reign
Since 1987, Nancy Pelosi has represented California's Eighth District in the House of Representatives. The Eighth District includes most of the City of San Francisco including Golden Gate Park, Fisherman's Wharf, Chinatown, and many of the diverse neighborhoods that make San Francisco a vibrant and prosperous community. Overwhelmingly elected by her colleagues in the fall of 2002 as Democratic Leader of the House of Representatives, Nancy Pelosi is the first woman in American history to lead a major party in the U.S. Congress.
Before being elected Leader, she served as House Democratic Whip for one year and was responsible for the party's legislative strategy in the House. On January 4, 2007, Nancy Pelosi was elected Speaker of the United States House of Representatives. She has been a proponent of increased investments in health research and authored legislation to create an independent national commission to assess the overall performance of the federal government before, during, and after the September 11 attacks.
Nancy Pelosi: Oh yes. Democrats have for a long time been prepared to govern, ready to lead and determined to make the American people proud. We have been working on our issues for a long time, to think in a big way.
You hear the campaign debates and people talk about specifics of policy and the rest. Here in Congress, we've been talking about a bigger vision, a vision that goes back to our founders. They were, again, entrepreneurial thinkers, big thinkers about the future.
So if we're talking about the creation of jobs, we talk about innovation; they were entrepreneurs, our founders. They believed in public/private partnerships, and we, in that spirit, do as well. It's absolutely essential if our economy is going to grow that that private sector is in the lead on that.
Next we talk about the issue of healthcare. Everybody talks about access to healthcare. Democrats talk about access to what? Democrats in the Congress are talking about a bigger vision, not just healthcare but a healthier America. It's about diet, not diabetes. It's about prevention, not amputation. It's about thinking about how we raise our children and their lifestyle, and how we prevent them from falling victim to dispositions because of bad habits early on. It's about, again, major investments in science, in terms of basic biomedical research and technology, to make sure that every person in America has the customized personalized care he or she needs.
When we talk about building the infrastructure of America, back to our founders--Thomas Jefferson--he had a plan for building the infrastructure, the Erie Canal, the Cumberland Road into the Louisiana Purchase and following the Lewis and Clark expedition. He tasked for that to his Secretary of the Treasury.
A hundred years later, in honor of the centennial, Theodore Roosevelt--another great leader of our country, a Republican--as part of his infrastructure agenda, he established the National Park Service.
A hundred years later, in that tradition, building the infrastructure in a green way takes us to preserving our planet. Again, science and technology and engineering--all of it--coming together to preserve the planet for reasons that relate to our security, our economy, our environmental health and our moral responsibility.
I say it in four words: science, science, science and science.
It's absolutely essential that we have these investments in health sciences and hard sciences so that we can think in a big way about how we go forward. So we're ready. Again, we have the foundation, we have the vision, we have the knowledge, we have the judgment and we have the plan.
And I believe that the American people are with us. And when they learn more about our agenda, more will be with us. And we have the leadership, and when we have a Democratic President, yes we'll be able to lead, govern and make people proud. And we'll do so in a way that lives up to the highest ethical standard, that is fiscally responsible--no new deficit spending--and we'll do so with the most civility and bipartisanship. That's our responsibility to our founders, to the American people and to our future.

It's just the current cycle that involves opiates, but methamphetamine, cocaine, and others have caused the trajectory of overdoses to head the same direction
- It appears that overdoses are increasing exponentially, no matter the drug itself
- If the study bears out, it means that even reducing opiates will not slow the trajectory.
- The causes of these trends remain obscure, but near the end of the write-up about the study, a hint might be apparent
Through computationally intensive computer simulations, researchers have discovered that "nuclear pasta," found in the crusts of neutron stars, is the strongest material in the universe.
- The strongest material in the universe may be the whimsically named "nuclear pasta."
- You can find this substance in the crust of neutron stars.
- This amazing material is super-dense, and is 10 billion times harder to break than steel.
Superman is known as the "Man of Steel" for his strength and indestructibility. But the discovery of a new material that's 10 billion times harder to break than steel begs the question—is it time for a new superhero known as "Nuclear Pasta"? That's the name of the substance that a team of researchers thinks is the strongest known material in the universe.
Unlike humans, when stars reach a certain age, they do not just wither and die, but they explode, collapsing into a mass of neurons. The resulting space entity, known as a neutron star, is incredibly dense. So much so that previous research showed that the surface of a such a star would feature amazingly strong material. The new research, which involved the largest-ever computer simulations of a neutron star's crust, proposes that "nuclear pasta," the material just under the surface, is actually stronger.
The competition between forces from protons and neutrons inside a neutron star create super-dense shapes that look like long cylinders or flat planes, referred to as "spaghetti" and "lasagna," respectively. That's also where we get the overall name of nuclear pasta.

The researchers' computer simulations needed 2 million hours of processor time before completion, which would be, according to a press release from McGill University, "the equivalent of 250 years on a laptop with a single good GPU." Fortunately, the researchers had access to a supercomputer, although it still took a couple of years. The scientists' simulations consisted of stretching and deforming the nuclear pasta to see how it behaved and what it would take to break it.
While they were able to discover just how strong nuclear pasta seems to be, no one is holding their breath that we'll be sending out missions to mine this substance any time soon. Instead, the discovery has other significant applications.
One of the study's co-authors, Matthew Caplan, a postdoctoral research fellow at McGill University, said the neutron stars would be "a hundred trillion times denser than anything on earth." Understanding what's inside them would be valuable for astronomers because now only the outer layer of such starts can be observed.
"A lot of interesting physics is going on here under extreme conditions and so understanding the physical properties of a neutron star is a way for scientists to test their theories and models," Caplan added. "With this result, many problems need to be revisited. How large a mountain can you build on a neutron star before the crust breaks and it collapses? What will it look like? And most importantly, how can astronomers observe it?"
Another possibility worth studying is that, due to its instability, nuclear pasta might generate gravitational waves. It may be possible to observe them at some point here on Earth by utilizing very sensitive equipment.
The team of scientists also included A. S. Schneider from California Institute of Technology and C. J. Horowitz from Indiana University.

Scientists think constructing a miles-long wall along an ice shelf in Antarctica could help protect the world's largest glacier from melting.
- Rising ocean levels are a serious threat to coastal regions around the globe.
- Scientists have proposed large-scale geoengineering projects that would prevent ice shelves from melting.
- The most successful solution proposed would be a miles-long, incredibly tall underwater wall at the edge of the ice shelves.
The world's oceans will rise significantly over the next century if the massive ice shelves connected to Antarctica begin to fail as a result of global warming.
To prevent or hold off such a catastrophe, a team of scientists recently proposed a radical plan: build underwater walls that would either support the ice or protect it from warm waters.
In a paper published in The Cryosphere, Michael Wolovick and John Moore from Princeton and the Beijing Normal University, respectively, outlined several "targeted geoengineering" solutions that could help prevent the melting of western Antarctica's Florida-sized Thwaites Glacier, whose melting waters are projected to be the largest source of sea-level rise in the foreseeable future.
An "unthinkable" engineering project
"If [glacial geoengineering] works there then we would expect it to work on less challenging glaciers as well," the authors wrote in the study.
One approach involves using sand or gravel to build artificial mounds on the seafloor that would help support the glacier and hopefully allow it to regrow. In another strategy, an underwater wall would be built to prevent warm waters from eating away at the glacier's base.
The most effective design, according to the team's computer simulations, would be a miles-long and very tall wall, or "artificial sill," that serves as a "continuous barrier" across the length of the glacier, providing it both physical support and protection from warm waters. Although the study authors suggested this option is currently beyond any engineering feat humans have attempted, it was shown to be the most effective solution in preventing the glacier from collapsing.

An example of the proposed geoengineering project. By blocking off the warm water that would otherwise eat away at the glacier's base, further sea level rise might be preventable.
But other, more feasible options could also be effective. For example, building a smaller wall that blocks about 50% of warm water from reaching the glacier would have about a 70% chance of preventing a runaway collapse, while constructing a series of isolated, 1,000-foot-tall columns on the seafloor as supports had about a 30% chance of success.
Still, the authors note that the frigid waters of the Antarctica present unprecedently challenging conditions for such an ambitious geoengineering project. They were also sure to caution that their encouraging results shouldn't be seen as reasons to neglect other measures that would cut global emissions or otherwise combat climate change.
"There are dishonest elements of society that will try to use our research to argue against the necessity of emissions' reductions. Our research does not in any way support that interpretation," they wrote.
"The more carbon we emit, the less likely it becomes that the ice sheets will survive in the long term at anything close to their present volume."
A 2015 report from the National Academies of Sciences, Engineering, and Medicine illustrates the potentially devastating effects of ice-shelf melting in western Antarctica.
"As the oceans and atmosphere warm, melting of ice shelves in key areas around the edges of the Antarctic ice sheet could trigger a runaway collapse process known as Marine Ice Sheet Instability. If this were to occur, the collapse of the West Antarctic Ice Sheet (WAIS) could potentially contribute 2 to 4 meters (6.5 to 13 feet) of global sea level rise within just a few centuries."
