The Weightless Family

First-Hand Look: One Family's Unforgettable Zero Gravity Holiday, Space.com

"Like many American families across the country, the Stern family of Colorado celebrated the Fourth of July holiday together on Sunday. But instead of a traditional barbecue or picnic, the family took to the skies for a novel weightless daytrip on a Zero Gravity Corporation (Zero-G) aircraft. Here, journalist and eldest Stern daughter Sarah Stern describes the experience of the July 4th trip, which was arranged as part of a project led by her father - planetary scientist Alan Stern - investigating the scientific uses of zero gravity and suborbital spaceflights at the Southwest Research Institute."

Wireless Sensor Technology for Real-Time Applications

The ability to make real-time decisions based on pressure, temperature, or flow measurements while a process is running can provide significant advantages in a measurement and control system. These advantages can be expressed in different ways such as cost savings through improved resource management, or reduced reliability upon mobile workers. While measurement data can be used to dynamically control a process, it can also be displayed over a network to allow remote monitoring of the process status in real time. Rising pressures, temperatures, or vibration intensity can easily be adjusted if the appropriate personnel are aware of faulty conditions. As data is collected for process control or a SCADA system, it can also be archived for future reference when a review of process trends could provide additional improvements.

The Immense Madness and Greed in the Gulf

??Today environmental attorney Mike Pappantonio appeared on an MSNBC show Hardball, and said that there is no $20 billion escrow account funded by BP for the Gulf Coast victims.  Repeat.  There is no account.  The account does not exist except as a version of a  ‘moral promise’.   Unfortunately, corporations have no morals. They exist to make money, and that is their only purpose.  A moral promise from a corporation is impossible.

Pappantonio also said BP is also in talks with bankruptcy attorneys.   BP is not putting money into an escrow account, and their agreement with the Obama administration is not worth the paper it’s not written on, because there is still a legally binding $75 million dollar cap on what they legally have to pay to “clean up” the entire Gulf of Mexico.  They have already spent more than that, and  BP has said they would not be bound by that cap, but they have given us little reason to trust them.   What does this all mean?  This means that the American taxpayer,  proud American oil and gas addicts, will be footing the bill for this disaster, after the bankruptcy occurs.   There is no ethical or economic justice on the horizon for anyone in this mess.

Meanwhile, the Gulf of Mexico continues to suffer from a slow, agonizing death at the hands of BP,  and Transocean (whatever happened to them?). The A Whale ship (seen below in video) has been at least partially deployed and they are testing its effectiveness.  They report they are about a week ahead of schedule on the relief wells, which may not work.  Today there was also more talk of “imploding” the well via a very large explosion.

The oil continues to gush into the water.  Fish and other life continue to die. The environmental impact has all gotten worse instead of better, because BP is adding immense amounts of air pollution  to the disaster by burning everything they are capturing.  They are destroying everything they possibly can, including evidence of oil by their enormous use of dispersants (which continues) and by reportedly hiding the workers who have gotten sick from the clean up work, and by trucking in sand to cover up oily beaches.   BP has been hiding the scope of this disaster from the beginning.  Remember, there is no ethical or moral obligation on the part of corporations to do anything when they F up whatever, and BP so far has done what they have done due to political pressure. The political pressure urging them to do the right thing has been strongly counteracted by the right-wing politicians screaming about losing jobs.**  (see below for a parallel story).

It’s no surprise that scientists are finding growing evidence of oxygen-starved “dead zones” in the Gulf of Mexico near the BP oil spill area. In some areas, methane presence is as high as 100,000 times normal levels, sucking oxygen out of the water and killing off marine species, and forcing surviving animals to move from their traditional habitats.  [...]

When top-down meets bottom-up: EUV and X-ray interference lithography for sub-20-nm features

After achieving the 45-nm process, today's semiconductor industry is nearing the 20-nm process and looking for techniques that would enable sub-22-nm-half-pitch line patterns. Following the continuous increase in exposure tool numerical aperture, researchers are pursuing reductions in exposure wavelengths. This effort had them look at extreme ultraviolet (EUV: 13.4 nm in wavelength) as an exposure light source. Unlike the numerical aperture engineering, change of a light source to EUV demands development of its related components, such as photoresist and optics. Until a reliable solution for EUV lithography is developed, EUV interference lithography (EUVIL) would not solely advance the lithographic technology but would also help to optimize photoresist materials for EUV.

A simple, one-step process to fabricate three-dimensional graphene macrostructures

Given the massive interest and rapid developments in graphene research, scientists are now convinced that the controlled preparation of graphene-based materials with hierarchical and well-defined structures will pave the way for achieving high-performance applications of graphene in various technological fields such as optoelectronics, energy storage, polymer composites and catalysis. Self-assembly techniques have become some of the most effective strategies for this purpose. Although 2D self-assembly of graphene has been studied extensively from the perspectives of fundamental research and commercial applications, 3D self-assembly of 2D nanoscale graphene into functional macrostructures with well-defined networks remains as a great challenge and represents an important hurdle towards practical applications. Researchers in China have now provided a solution to this problem by demonstrating the successful preparation of self-assembled graphene hydrogel via a one-step hydrothermal process.
