Here is an excellent post about particle jets that take material from around a black hole, (around one solar mass per year) and eject it at speeds of up to 100,000 kilometers per second. It is these outflows that limit a black hole's growth since that material would otherwise be eaten or released via the primary particle jet.

The World in 2100 by Michio Kaku

An excellent vision of 2100 by Michio Kaku.  I often think about what life will be like 100 years from now, just think about how different life is from 100 years ago.  Also keep in mind that the rate of scientific advancement is also increasing.

Makes You Think Twice...

What if humans were twice as intelligent? - Technology & science - Science - LiveScience - msnbc.com:

Would it be a blessing or a curse?
"Experiencing the world with a higher IQ might be more interesting for most people. They might enjoy reading more, might have a greater depth of appreciation for certain things and more insight into life,"  said Richard Haier, a neuroscientist and professor emeritus at the University of California at Irvine who studies intelligence. 


"Intelligence is independent of personality and emotion, so you can have very intelligent people who are also just kind of crazy people," Haier said. "Even if everyone had an IQ of 200, you'd have exactly the same range of personalities as you have now, and because that's a determining factor in how good your society is, you won't necessarily have a better society."  
But it comes with a warning: "The evil corporate villains would be smarter than ever, but so would the government officials who were writing and enforcing the safety regulations! Who would win? Who knows?" he wrote.


I think the good outweighs the bad.  Think of how politics would be changed by a better educated constituency.  What about the effect on science? Or crime.  One good point made by Natalie Wolchover is that there will likely be a distinction between the haves and the have-nots.

X Particle Explains Dark Matter and Antimatter

Two of the fundamental mysteries of physics now has a new theory to explain them both.  The "X-Particle" is a hypothetical particle that is thought to decay into matter and neutrons.  Created by the big bang, the X-particle had a companion particle the Anti-X-particle, which decayed into anti-matter and neutrons.  It is these particles which have decayed into the matter which we can see and the dark matter we cannot.  This theory has proposed new concepts that could explain why dark matter is so prevalent in the universe.

Largest 3D Map Of The Night Sky Ever Assembled

This is the largest 3D image of the cosmos that has ever been shown.  With over a trillion pixels, it would require over 500,000 high definition TVs to show in it's entirety.  According to David Shinga of New Scientist; "It is actually a collection of millions of images taken since 1998 with a 2.5-meter telescope at Apache Point Observatory in New Mexico. The project, called the Sloan Digital Sky Survey, is now in its third phase, called SDSS-III"

It's thought that this map will be helpful in understanding dark energy, which is believed to comprise 70% of our universe.  It has also helped scientists to discover tiny "dwarf" galaxies that orbit the Milky Way.

BBC News - Neutrino 'ghost particle' sized up by astronomers

Neutrinos are particles that can travel through 1 light year of lead without interacting with any of the lead atoms.  It is extremely small and light and is responsible for a small portion of dark matter.  Professor Lahav believes neutrinos are a minor component of cold dark matter, the mysterious "stuff" which comprises some 25% of the Universe and more than 80% of matter in the Universe.

"The neutrino is squeezed into that slice [of the Universe] that is dark matter. But it probably accounts for less than one percent of that dark matter," he told BBC News.

The neutrino particle comes in three "flavours": muon, tau and electron. In a recent experiment, physicists caught a neutrino in the act of changing from one type to another.

Ununquadium: Element 114

Named Ununquadium, the latest addition to the periodic table is an artificial radioactive element that is the heaviest know.  The nucleus decays to lead and the element is known to stay stable for approximately 2.6 seconds before decaying.

BBC News - US experiment hints at 'multiple God particles'

The Higgs Boson is the subatomic particle that physicists theorize as the particle responsible for attributing mass.  However, it has yet to be detected. Summer results from Fermilab, the LHC's US rival, suggest physicists could be hunting five particles, not one. The idea of multiple Higgs-like bosons is supported by results gathered by the DZero experiment at the Tevatron particle accelerator

"The DZero results showed much more significant "asymmetry" of matter and anti-matter - beyond what could be explained by the Standard Model.

Bogdan Dobrescu, Adam Martin and Patrick J Fox from Fermilab say this large asymmetry effect can be accounted for by the existence of multiple Higgs bosons."

Understanding Clouds: How Much Do We Know?

Clouds are more than just the muse of a poet. They play a major role in climate change yet there are still many unanswered questions. Clouds are known to be the result of "a complex interplay of fluid dynamics, turbulence, convection and mixing" that are not exactly scalable or easy to predict.  Click the link below and hear a podcast on what we know and what we don't.

High Fructose Corn Syrup: Sugar May Be Bad But This Sweetener Is Far More Deadly

A great article by Dr. Mercola about why consuming high levels of high fructose can have deadly effects.  From Dr. Mercola:

"There are two reasons fructose is so damaging:

1. Your body metabolizes fructose in a much different way than glucose. The entire burden of metabolizing fructose falls on your liver.

2. People are consuming fructose in enormous quantities, which has made the negative effects much more profound."

Scientists Identify Gene Linked to Aging in Humans

Scientists believe that they have identified the gene process that is linked to aging and the results are very interesting.  For example, people age at different rates as programmed by DNA.

A structure called a telomeres, inside the gene seems to be the candlestick that is burnt by time.  As cells divide and are continually replaced, the wick of the telomere will continue to shorten.  Inheritance dictates how long the telomere is to begin life and the rate of shortening also seems to be influenced by inheritance.

Professor Tim Spector from King's College London and director of the TwinsUK study, who co-led this project, added: "Genetically susceptible people may age even faster when exposed to proven 'bad' environments for telomeres like smoking, obesity or lack of exercise - and end up several years biologically older or succumbing to more age-related diseases."

Half Human and Half Virus; A New View

I have been sitting on this, trying to make sense of it.  Basically, we are the result of a DNA virus.  Have a great weekend!

Seriously, some interesting facts about what you are:

1. Scientists expected 100,000 genes in the human DNA, we found 20,000
2. 34% of those 20,000 genes are considered "junk" because they copy themselves but serve no function.
3. Half of the human genome can be traced to a virus.
4. The virus genes have shown to be vital to the formation of specific organs in the human body.

In short, it is interesting to note that retroviruses that have symbiosis with our DNA may have helped to shape our evolution and development.

Scientists Tap Volcano Power

Scientists have discovered how to tap the geothermal energy of the Earth.  With 17,000 islands ranging from the Indian Ocean to the Pacific Ocean, hundreds of active volcanoes represent close to 40 percent of the world's geothermal energy potential.


One geothermal plant already exists in Kamojang, Java.  Built in 1982 can convert volcanic heat into electricity at much lower costs and with less pollution than coal plants.


A significant ($12 Billion) amount is required to further the technology, but tapping geothermal energy is a viable option to fossil fuels.

Physicists Investigate Possibility of an 'Unhiggs'

This figure represents a five-dimensional diagram relevant to how the Unhiggs affects certain parameters in particle physics models. Physicists are calculating the properties of the Unhiggs so that it will be recognized at the LHC, if it exists. Image credit: Falkowski and Pérez-Victoria.


The Unhiggs is the possibility that the Higgs-Boson doesn't exist.  It is the alternate theory which is really a "supermass" of a collection of particles that are in superposition.  So, measuring the mass of something involves defining the space in which that thing encompasses.  If measuring the mass of an orange, you wouldn't measure anything outside of the orange.  


However, in the quantum world, that orange can change to a watermelon, apple, peach or pumpkin during the time of the measurement.  Therefore, the measurement you get is a combination of all those fruit affecting the measurement for the instant that they were there.  This is similar to the Unhiggs theory which says that mass is formed as a combination of these superposition events.
