clipper's remarks: Hot damn! This is real progress. Thank god for science!

Canadian scientists have become the first in the world to decode the DNA of breast cancer cells, and have discovered, to their surprise, that the gene mutations in those tumours shift as the disease spreads.

The finding brings researchers unprecedented information about how breast cancer progresses and shows that the disease is a moving target that often changes the way it operates.

Researchers with the B.C. Cancer Agency say they made their discovery after decoding the entire genome of a patient's metastatic breast cancer and finding all the genome's mutations.

New Biomimicry in Digital Security - Ants Swarm to Protect Computers

Science Daily reports that biomimicry is playing a key role in upcoming computer security technology. By looking at the way ants call for backup and overpower invaders through sheer quantity of soldiers, security experts have devised a "digital ant" that will help human operators more quickly spot threats to computer systems.

stupendou writes with this excerpt from the New York Times: "Microscopes are invaluable tools to identify blood and other cells when screening for diseases like anemia, tuberculosis and malaria. But they are also bulky and expensive. Now an engineer, using software that he developed and about $10 worth of off-the-shelf hardware, has adapted cellphones to substitute for microscopes." But not based on optical magnification: the article explains that Aydogan Ozcan, a UCLA assistant professor of electrical engineering, has combined the wireless transmission abilities and imaging sensors now typical in wireless phones to make the phones capable of detecting cell abnormalities and more by capturing wave interference patterns from body fluids — like blood — and sending them on for analysis.

Chemical BPA in workers linked to sex problems

By MALCOLM RITTER, AP Science Writer Malcolm Ritter, Ap Science Writer – 2 hrs 1 min ago

NEW YORK – Male factory workers in China who got very high doses of a chemical that's been widely used in hard plastic bottles had high rates of sexual problems, researchers reported Wednesday.

The men in the study experienced BPA levels about 50 times higher than those faced by typical American men, said researcher Dr. De-Kun Li. "We don't know" whether more typical doses have similar effects, he said.

BPA is used in a wide variety of consumer products, including some hard plastic bottles and metal food or beverage cans. Several makers of baby bottles recently said they had stopped using the chemical. Some 90 percent of the U.S. population carries detectable levels in the urine.

The U.S. government recently announced new funding for research into BPA's effects.

GRB 090423 - the most distant known object in the Universe

In this week's edition of the science journal Nature, two international teams of astronomers report their observations of the most distant object yet seen in the Universe. Dubbed GRB 090423, the record-breaker is an example of a gamma-ray burst, the brightest and most violent explosions known to exist. The explosion is thought to accompany the catastrophic death of a very massive star as it ended its life, and is triggered by the centre of the star collapsing to form a black hole.

"This observation allows us to begin exploring the last blank space on our map of the Universe", said Professor Nial Tanvir, who led one of the teams.

10 ancient Greek writers you should know

clipper's remarks: Archimedes was a mathematician, engineer, inventor, physicist and astronomer. He is known for the invention of The Archimedes’ Screw, a mechanism for moving water that is still in use today. He also calculated the value of pi very precisely. Archimedes discovered how to define the volume of irregular objects by submerging them in water. According to legend, this discovery made him run out on the street naked (he was so excited that he forgot to get dressed) and cry “Eureka!” – I have found it.

SEAPLEX: Seeking the Science of the Great Pacific Ocean Garbage Patch

Wed, 11 Nov 2009 18:30:16 GMT

A thousand miles off California, the North Pacific Ocean Gyre contains one of the largest ecosystems on Earth--but it may be in danger from a deluge of accumulated plastic trash. Dubbed the "Great Pacific Ocean Garbage Patch," the debris at the center of the North Pacific Ocean has the potential to damage marine life and alter the biological environment.

From August 2-21, 2009, a group of doctoral students and research volunteers from Scripps Institution of Oceanography at UC San Diego embarked on an expedition aboard the Scripps research vessel New Horizon exploring the problem of plastic in the North Pacific Gyre

How much plastic is accumulating, how is it distributed, and how is it affecting ocean life? With their new results the researchers hope to provide critical, timely data to policy makers and combine Scripps' long tradition of Pacific exploration with focus on a new and pressing environmental problem.

The Relative Size of Things

Back in the 70s or 80s, IBM made a video called The Power of 10, which showed the relative size of things from the universe to the cell and the effect of adding a zero. In other words going from 1 meter to 10 meters to 100 meters and so on.

Now in the age of nanotechnology, and manipulating materials on the molecular scale, it's nice to see an interactive that shows the relative size of the small things. We're talking everything from coffee beans to carbon atoms. With viruses, bacteria, red blood cells and a host of other structures in between.

Cell Size and Scale is made possible by the Genetics Science Learning Center at the University of Utah. It's so great. Go ahead and interact.

Healthcare Provision Seeks To Embrace Prayer Treatments

Sun, 08 Nov 2009 03:49:49 GMT

clipped by: wiccantexan

Clip Source: www.latimes.com

Backed by some of the most powerful members of the Senate, a little-noticed provision in the healthcare overhaul bill would require insurers to consider covering Christian Science prayer treatments as medical expenses.

The provision was inserted by Sen. Orrin G. Hatch (R-Utah) with the support of Democratic Sens. John F. Kerry and the late Edward M. Kennedy, both of Massachusetts, home to the headquarters of the Church of Christ, Scientist.

The measure would put Christian Science prayer treatments -- which substitute for or supplement medical treatments -- on the same footing as clinical medicine. While not mentioning the church by name, it would prohibit discrimination against "religious and spiritual healthcare."

But critics say the measure could have a broader effect, conferring new status and medical legitimacy on practices that lie outside the realm of science.
