The Susan G. Komen foundation has reversed a controversial decision not to renew funding for some Planned Parenthood projects, the group said in a statement Friday.

“We want to apologize to the American public for recent decisions that cast doubt upon our commitment to our mission of saving women’s lives,” the statement said. “We will continue to fund existing grants, including those of Planned Parenthood, and preserve their eligibility to apply for future grants, while maintaining the ability of our affiliates to make funding decisions that meet the needs of their communities.”

Planned Parenthood said Tuesday that the foundation had “succumbed to political pressure” by cutting its funding for breast cancer screenings at Planned Parenthood amid increased scrutiny by [right-wing Republicans in] Congress over how Planned Parenthood provides abortion services.

The decision triggered strong emotions.

In Washington, at least 22 Senate Democrats signed a letter calling on Komen to reconsider its decision.

CREDO, which describes itself as the largest corporate donor to Planned Parenthood, said Thursday that 250,000 of its members had signed a petition urging the Komen Foundation to reverse its decision.

“The move is clearly connected to attempts by Republicans in Congress to defund Planned Parenthood,” the organization said in a statement. “In responding to questions about its decision, the foundation cited as its rationale a sham ‘investigation’ into Planned Parenthood launched by Republican Rep. Cliff Stearns.” who the group called “one of the most militant anti-choice members of Congress.”

A lifetime of thanks is owed to the thousands of Americans who stood up and voted with their wallets, voices and conscience against the cowardly decision made by Komen executives.

A special thanks to my sisters and brothers in the blogosphere who jumped to defend reproductive rights.

Scientists understand that Earth’s magnetic field has flipped its polarity many times over the millennia. In other words, if you were alive about 800,000 years ago, and facing what we call north with a magnetic compass in your hand, the needle would point to ‘south.’ This is because a magnetic compass is calibrated based on Earth’s poles. The N-S markings of a compass would be 180 degrees wrong if the polarity of today’s magnetic field were reversed. Many doomsday theorists have tried to take this natural geological occurrence and suggest it could lead to Earth’s destruction. But would there be any dramatic effects? The answer, from the geologic and fossil records we have from hundreds of past magnetic polarity reversals, seems to be ‘no.’

Reversals are the rule, not the exception. Earth has settled in the last 20 million years into a pattern of a pole reversal about every 200,000 to 300,000 years, although it has been more than twice that long since the last reversal. A reversal happens over hundreds or thousands of years, and it is not exactly a clean back flip. Magnetic fields morph and push and pull at one another, with multiple poles emerging at odd latitudes throughout the process. Scientists estimate reversals have happened at least hundreds of times over the past three billion years…

Earth’s polarity is not a constant. Unlike a classic bar magnet, or the decorative magnets on your refrigerator, the matter governing Earth’s magnetic field moves around. Geophysicists are pretty sure that the reason Earth has a magnetic field is because its solid iron core is surrounded by a fluid ocean of hot, liquid metal…The flow of liquid iron in Earth’s core creates electric currents, which in turn create the magnetic field. So while parts of Earth’s outer core are too deep for scientists to measure directly, we can infer movement in the core by observing changes in the magnetic field. The magnetic north pole has been creeping northward – by more than 600 miles (1,100 km) – since the early 19th century, when explorers first located it precisely. It is moving faster now, actually, as scientists estimate the pole is migrating northward about 40 miles per year, as opposed to about 10 miles per year in the early 20th century.

Another doomsday hypothesis about a geomagnetic flip plays up fears about incoming solar activity. This suggestion mistakenly assumes that a pole reversal would momentarily leave Earth without the magnetic field that protects us from solar flares and coronal mass ejections from the sun. But, while Earth’s magnetic field can indeed weaken and strengthen over time, there is no indication that it has ever disappeared completely. A weaker field would certainly lead to a small increase in solar radiation on Earth – as well as a beautiful display of aurora at lower latitudes — but nothing deadly. Moreover, even with a weakened magnetic field, Earth’s thick atmosphere also offers protection against the sun’s incoming particles.

I couldn’t resist posting this. I know a Christian science teacher who’s stuck into the idea of incoming solar activity roasting us on the playing field of life. I’m not certain if he plans to purchase some kind of anti-radiation suit or just move underground for a couple hundred years.

Maccone claims glass can unbreak – for example

Imagine if a cold cup of coffee spontaneously heated up as you watched. Or a cracked pane of glass suddenly un-broke. According to physicist Lorenzo Maccone at the Massachusetts Institute of Technology, you see things like this all the time – you just don’t remember.

In a paper published last week in Physical Review Letters, he attempts to provide a solution to what has been called the mystery of “the arrow-of-time”.

Briefly, the problem is that while our laws of physics are all symmetrical or “time-reversal invariant” – they apply equally well if time runs forwards or backwards – most of the everyday phenomena we observe, like the cooling of hot coffee, are not. They never seem to happen in reverse…

So why will your coffee spontaneously cool down, but not heat up?

Maccone’s solution is to suggest that in fact entropy-decreasing events occur all the time – so there is no asymmetry and no associated mystery about the arrow of time.

He argues that quantum mechanics dictates that if anyone does observe an entropy-decreasing event, their memories of the event “will have been erased by necessity“.

Maccone doesn’t mean that your memories will never form in the first place. “What I’m pointing out is that memories are formed and then are subsequently erased,” he tells me.

When you observe any system, according to Maccone, you enter into a “quantum entanglement” with it. That is, you and the system are entangled and cannot properly be described separately.

The entanglement, Maccone says, is between your memory and the system. When you disentangle, “the disentangling operation will erase this entanglement, namely the observer’s memory”. His paper derives this conclusion mathematically.

Smacks of philosophic Idealism to me. Mind over matter. Or mind over matter over mind over matter.

In any case, accounting for physical processes with non-material devices.
