You are still looking at mass as a web, theY are putting it down to a point.
Measuring the mass and determining the reasons for that mass of hadrons isn't the same as measuring the mass and determining the reasons for that mass of fundamental particles.

so.....the creation of higgs boson (which is a fundamental particle?) proves the existance of an 'overlaying field' (higgs field) which interacts with the other fundamental particles (electrons, neutrinos, quarks) and creates gravitational charge (which is mass). do I have this correct so far?
the creation of the higgs boson, was by slamming particles together in the accelerator at a specific speed (or energy) and measuring (over and over again) the energy output signature, which ended up matching the theoretical energy signature of higgs boson?
edit - so a boson is a subatomic particle (not a fundamental particle), but the higgs boson has no spin and zero electric or color charge.
edit2 - the overlying field is just a collection of higgs bosons (creating a scalar field) which react with fundamental particles to create gravitational charge (otherwise measured as mass). I think. If so, very cool.
The Higgs is both a subatomic particle, and a fundamental particle. Subatomic in that it's smaller than an atom, and fundamental in that it's not believed to be divisible. The last one could change at some point.
According to quantum mechanics every field is composed of force carriers (bosons), like the Higgs. The electromagnetic field can be thought of as a field, or web, or thought of as a bunch of photons everywhere. The strong nuclear force can be thought of as a force binding quarks together, and protons and neutrons together, or as gluons and mesons like pions buzzing around these other particles keeping them together. Even gravity is thought to be composed of gravitons, though they have yet to be discovered.

Almost exactly one year after discovering dwarf planet Pluto's fourth moon - though not before actually naming poor little P4 - NASA announced Wednesday a fifth moon has been discovered orbiting the ex-planet.

This is mostly philosophy, but it concerns the implementation of science-based technology.
Some fairly eminent philosophers in their new book call for "moral bioenhancements" to be made to humankind to cope with looming disasters that our moral psychology is not evolved enough to handle. Our moral core concerns small social groups, the near future, and causality, for instance, when, in the modern world with all that modern technology has given us, we are faced with global problems that may not fully manifest themselves until far into the future.
Modern technology provides us with many means to cause our downfall, and our natural moral psychology does not provide us with the means to prevent it. The moral enhancement of humankind is necessary for there to be a way out of this predicament. If we are to avoid catastrophe by misguided employment of our power, we need to be morally motivated to a higher degree (as well as adequately informed about relevant facts). A stronger focus on moral education could go some way to achieving this, but as already remarked, this method has had only modest success during the last couple of millennia. Our growing knowledge of biology, especially genetics and neurobiology, could deliver additional moral enhancement, such as drugs or genetic modifications, or devices to augment moral education.
The current issue has a bunch of articles about human moral enhancement through science, but the other ones are pay to view, unfortunately.

Roughly speaking, isotopes are radioactive and decay over time (emit particles of their own) and eventually turn into something else. This generally happens quickly, but some isotopes, like uranium, take a very, very long time, and these are used in radiodating processes to determine the age of certain things (certain uranium isotopes decay into certain lead isotopes, and depending on how far along this process is, a rough age can be determined).
Up to now, radioactive decay was always taken to be a constant. It didn't change. But now they've found it does change, and the rate of change is determined by the sun! Not only that, but it depends on the seasons, too.
They talk about this being able to help predict solar flares, but there's something else that may result from this new finding: the Young Earth Creationists will latch onto it like a pitbull on a leg bone. If the constancy of radiocarbon dating is in question, perhaps all instances of its use to date things (like the Earth) can now be called into question. Perhaps the Earth is much, much, much younger than scientists currently believe!
If you look at the paper, however, you will see the decay rate changes rise and fall over monthly periods as the sun rotates, and the overall decay rate change is <1%. So, unfortunately for the Young Earth Creationists, this finding means the Earth could just as easily be older than currently thought by scientists as easily as it could be younger, but it would still not make much of a difference, as a 1% change would not be close to enough to go from a n Earth that is over 4 billion years olf to one barely 5,000 years old.

"A hypersonic aircraft launched by the Air Force Tuesday spiraled out of control and was destroyed before it could reach its goal of speeding to 4,600 mph, Pentagon officials said Wednesday.
The third test of the X-51A Waverider was launched Tuesday off the California coast from a B-52 modified bomber aircraft and was to fly for 300 seconds, reaching hypersonic speeds of Mach 6, but only flew for 16 seconds, according to the Air Force."
Canada's Fine Guidance Sensor delivered to NASA's James Webb Space Telescope.

"This is an exciting event," said Scott Lambros, Webb telescope Instrument Systems Manager at NASA Goddard. "The FGS instrument is part of the integrated control system that performs the extremely fine pointing and stability needed for the Observatory; while the NIRISS instrument will provide great science and new discovery space. This milestone is the culmination of many years of hard work by our Canadian partners. We have had great cooperation between the FGS team and the Webb telescope team and look forward to continued cooperation integrating the instrument into the ISIM and Observatory."
So not really sure if this warrants it's own thread, but I read something the other day regarding India preparing for a mission to Mars in 2013. Awesome for their space program, but with Curiosity there right now, and the previous rovers not to mention the other satellites in the area, how important is this mission anyway? Other than showing the world that India has the ability to send a craft to Mars?
Main part of the question now is, why isn't there a Global Space Agency where they would pool their resources together (funding, brain power) and work together to achieve the desired goals?
This would reduce redundancy, be more efficient in the end, and the achievements would be far greater. As it stands now, NASA is working on a shoe string budget and the American Government isn't really interesting in adding more money to the budget, instead it is relying on the private sector.
I just think that we would be able to make larger leaps if the space agencies of the world got together. That's all.

It would be like the UN... Just argue and accomplish nothing.
I personally think the more countries throwing their hats into the space game the better. Competition fosters innovation.

I'm not sure if this constitutes as "important" but I thought it was pretty cool:
Quote:
A human skull dated to about 2,684 years ago with an "exceptionally preserved" human brain still inside of it was recently discovered in a waterlogged U.K. pit
Quote:
Laser imaging, chemical analysis and other examinations revealed that the brain naturally preserved over the millennia. The scientists found no evidence for bacterial or fungal activity, and described the tissue as being "odorless…with a resilient, tofu-like texture."
