Today, the University of Colorado at Boulder made an announcement regarding a very promising technology:

Known as optical frequency comb spectroscopy, the technique is powerful enough to sort through all the molecules in human breath and sensitive enough to distinguish rare molecules that may be biomarkers for specific diseases

Combined with other rapid-response technologies, this could be part of the detection side of a BioShield, a technological immune system for humanity.

The optical frequency comb is a very precise laser for measuring different colors, or frequencies, of light, said Ye. Each comb line, or “tooth,” is tuned to a distinct frequency of a particular molecule’s vibration or rotation, and the entire comb covers a broad spectral range — much like a rainbow of colors — that can identify thousands of different molecules.

Since a journal article was submitted to the Royal Society of Chemistry, the U of Alberta researchers have already made the processor and unit smaller and have brought the cost of building a portable unit for genetic testing down to about $100 Cdn. In addition, these systems are also portable and even faster (they take only minutes). Backhouse, Elliott and McMullin are now demonstrating prototypes of a USB key-like system that may ultimately be as inexpensive as standard USB memory keys that are in common use – only tens of dollars. It can help with pandemic control and detecting and control tainted water supplies.

This development fits in with my belief that there should be widespread inexpensive blood, biomarker and genetic tests to help catch disease early and to develop an understanding of biomarker changes to track disease and aging development. We can also create adaptive clinical trials to shorten the development and approval process for new medical procedures

The device is now much smaller than size of a shoe-box (USB stick size) with the optics and supporting electronics filling the space around the microchip

According to ScienceDaily:

The British-American biotech company Acambis reports the successful conclusion of Phase I trials of the universal flu vaccine in humans. The universal influenza vaccine has been pioneered by researchers from VIB and Ghent University. This vaccine is intended to provide protection against all ‘A’ strains of the virus that causes human influenza, including pandemic strains. Therefore, this vaccine will not need to be renewed annually.

What would make this new vaccine different from the ones already available is that it would target M2e, a conserved region of influenza “A” strains. Since that part doesn’t constantly mutate and about 2/3 of seasonal epidemics and all pandemics are due to type “A” strains, it could be a very efficient weapon against repeats of the “Spanish Flu” (1918−1919) that killed at least 50 million people worldwide. Only the future will tell if phase II and III trials are successful.

A 582,970 base pair sequence of DNA has been synthesized.

It’s the first time a genome the size of a bacterium has chemically been synthesized that’s about 20 times longer than [any DNA molecule] synthesized before.

This is a huge increase in capability. It has broad implications for DNA nanotechnology and synthetic biology.

The New York Times is reporting today that the continued acceleration of the rate at which the Greenland ice sheets are melting has scientists scrambling for answers. In particular, a combination of changes has the glaciologists particularly concerned. They say the accumulation of meltwater on the surface of the ice in the form of ponds and streams absorbs as much as four times more heat than the lighter-colored ice, thereby accelerating the surface’s rate of melting.

Additionally, this meltwater eventually finds its way to bedrock, where it appears to slightly lubricate the surface between ice and rock, facilitating more rapid ice shifting towards the ocean. A third factor in the trifecta is the breakup of substantial semi-submerged clots of ice that typically block narrow fjords. As these blockages break up, the flow of the frozen glacial rivers accelerates.

While there is still a tremendous amount about this cycle that remains undiscovered, what is clear is that the best estimates to date have fallen far short in terms of the speed at which these rare environments are changing. Although questions remain about how much of these changes are cyclical and how much is due precisely to man-originated global warming, we must gain a more complete understanding of these events so that we can take whatever steps we must to ameliorate any damage we’ve caused before the situation becomes so critical that massive changes come about as a result of our negligent handling of our environment.

Planning for the first Lifeboat Foundation conference has begun. This FREE conference will be held in Second Life to keep costs down and ensure that you won’t have to worry about missing work or school.

While an exact date has not yet been set, we intend to offer you an exciting line up of speakers on a day in the late spring or early summer of 2008.

Several members of Lifeboat’s Scientific Advisory Board (SAB) have already expressed interest in presenting. However, potential speakers need not be Lifeboat Foundation members.

If you’re interested in speaking, want to help, or you just want to learn more, please contact me at [email protected].

Determining the structure of a protein called hemagglutinin on the surface of influenza B is giving researchers at Baylor College of Medicine and Rice University in Houston clues as to what kinds of mutations could spark the next flu pandemic.

This is interesting research and progress in understanding and possibly blocking changes that would lead to pandemics.

In a report that goes online today in the Proceedings of the National Academy of Sciences (PNAS), Drs. Qinghua Wang, assistant professor of biochemistry and molecular biology at BCM, and Jianpeng Ma, associate professor in the same department and their colleagues describe the actual structure of influenza B virus hemagglutinin and compare it to a similar protein on influenza A virus. That comparison may be key to understanding the changes that will have to occur before avian flu (which is a form of influenza A virus) mutates to a form that can easily infect humans, said Ma, who holds a joint appointment at Rice. He and Wang have identified a particular residue or portion of the protein that may play a role in how different types of hemagglutinin bind to human cells.

“What would it take for the bird flu to mutate and start killing people” That’s the next part of our work,” said Ma. Understanding that change may give scientists a handle on how to stymie it.

A new biosensor developed at the Georgia Tech Research Institute (GTRI) can detect avian influenza in just minutes. In addition to being a rapid test, the biosensor is economical, field-deployable, sensitive to different viral strains and requires no labels or reagents.

This kind of technology could be applied to real time monitoring of other diseases as well.

“We can do real-time monitoring of avian influenza infections on the farm, in live-bird markets or in poultry processing facilities,” said Jie Xu, a research scientist in GTRI’s Electro-Optical Systems Laboratory (EOSL)
