Flying toward the Light: Birds as Quantum Navigators
Reverse-Engineering the Quantum Compass of Birds

Scientists are coming ever closer to understanding the cellular navigation tools that guide birds in their unerring, globe-spanning migrations.
The latest piece of the puzzle is superoxide, an oxygen molecule that may combine with light-sensitive proteins to form an in-eye compass, allowing birds to see Earth’s magnetic field.
“It connects from the subatomic world to a whole bird flying,” said Michael Edidin, an editor of Biphysical Journal, which published the study last week. “That’s exciting!”
The superoxide theory is proposed by Biophysicist Klaus Schulten of the University of Illinois at Urbana-Champaign, lead author of the study and a pioneer in avian magnetoreception. Schulten first hypothesized in 1978 that some sort of biochemical reaction took place in birds’ eyes, most likely producing electrons whose spin was affected by subtle magnetic gradients.
In 2000, Schulten refined this model, suggesting that the compass contained a photoreceptor protein called cryptochrome, which reacted with an as-yet-unidentified molecule to produce pairs of electrons that existed in a state of quantum entanglement — spatially separated, but each still able to affect the other.
According to this model, when a photon hits the compass, entangled electrons are scattered to different parts of the molecule. Variations in Earth’s magnetic field cause them to spin in different ways, each of which leaves the compass in a slightly different chemical state. The state alters the flow of cellular signals through a bird’s visual pathways, ultimately resulting in a perception of magnetism.
Far-fetched as it sounds, subsequent research from multiple groups has found cellular evidence of such a system. Molecular experiments suggest that it’s indeed sensitive to Earth’s geomagnetics, and computational models suggest a level of quantum entanglement only dreamed of by physicists, who hope to use entangled electrons to store information in quantum computers.
But though cryptochrome is likely part of the compass, the other part is still unknown. In April, another group of magnetoreception researchers showed that oxygen could interact with cryptochrome to producethe necessary electron entanglements. Schulten’s latest proposed role for superoxide, an oxygen anion found in bird eyes, fits with their findings.
Edidin cautioned that “this is still not an experimental demonstration. It’s a possibility.”
As for the perceptual result of the compass, it remains a mystery. Some researchers think birds might see a dot at the edge of their vision, swiveling according to the direction they’re facing. Others think it might produce effects of color or hue. Perhaps migrating birds fly towards the light.

"Know why I am the way I yam?"
I had to read this 3 times ...
Best day? Well, it certainly was right up there with “best days” of year’s gone by, as far as the attendance goes. Today was “Friend Day” at Bible Baptist Church of Olorien. Our people outdid themselves with invitations to friends and neighbors. Our congregation of 200 swelled today to 840! Praise the Lord!
Meanwhile, overnight in Charm City ...
Tornado Touches Down, Leaves Damage

Storm Damage Slideshow

Suzanne Collins reports National Weather Services believes it was a tornado that caused the damage.
The funnel cloud touched down in two places about five miles apart in the Back River area, and it left a lot of wreckage in its wake.
A waterfront home on Brown Creek is crushed by a fallen tree pulled up by what the Weather Service believes was a tornado.
6 Shot Near Bar Early Saturday Morning
Police say one person has died, one is in critical condition and the other four are being treated at the hospital.
The violence broke out on Oliver Street outside the Honey Hole Bar near closing time. According to police, at least one shooter approached from Patterson Park and began firing.
Police aren't yet saying what prompted the shooting spree.
Multiple Fatalities Feared In Street Racing Crash
State Police confirm one driver lost control, hitting two cars that were parked at the end of the illegal track. A group of people were standing at the finish line; some people were seated inside the cars.
Two people were struck and killed when that car lost control. One person sitting in one of the cars suffered injuries that are not life threatening.
One of the people killed is identified as 21-year-old Mary Kathryn Michele Abernathy, of Columbia. Her 20-year-old boyfriend, who lives in La Plata, was also killed. His identity is being withheld, pending notification of his family.
Both were pronounced dead at the scene.

A.N. Wilson returns to the faith
Believe Again: A. N. Wilson Returns to the Faith

BreakPoint
May 1, 2009
Two decades ago, A. N. Wilson wrote a critically acclaimed biography of C.S. Lewis. This and some other of his writings led some Christians to hope that Wilson might become what Alan Jacobs once called “that figure for whom so many have been waiting for so long, The Next C. S. Lewis.”
It therefore came as a surprise and a disappointment when Wilson publicly repudiated his Christian faith a few years later and became a mocker of Christianity.
Yet, this past Easter, in the U.K.’s Daily Mail, Wilson was urging British Christians not be cowed by “sneering” and “self-satisfied” critics like Richard Dawkins.
A. N. Wilson, you see, has returned to the faith. Why? In large measure because of the strongest evidence for the truth of the Gospel—that is, its impact on people’s lives.

Habari Yako? Medical Update
As always, we thank you for your prayers and thoughts for this ministry. Please pray for the medical group as they minister one more time this coming Wednesday, and for the rest of the group as they will hold a day camp at our Christian school, and then minister in the Wed. evening service. God Bless and give you a good week.
An 11-Year Old College Graduate?
Moshe Kai Cavalin, 11, graduates with honors from East Los Angeles Community College with a Associate Arts degree in Liberal Studies this week, but just don't call him a genius.
"I consider myself a regular kid who works hard and does his best," says this only child of a Taiwanese mother and an Israeli father.
When Cavalin started college at the age of 8, he may have been the youngest person in class, but he ended up tutoring some of his 19- and 20-year-old classmates in math and science. Cavalin was one of 3 in the school graduating with a 4.0 GPA.
Astrophysics is his passion. Albert Einstein and Bruce Lee are among his idols.
Do you understand this parable?
