And a shifting speed of light could revise current views about the evolution of the infant universe. Scientists think that a period of inflation caused the newborn cosmos to expand extremely rapidly, creating a universe that is uniform across vast distances. That uniformity is in line with observations: The cosmic microwave background, light that emerged about 380,000 years after the Big Bang, is nearly the same temperature everywhere scientists look. But cosmologist João Magueijo of Imperial College London has a radical alternative to inflation: If light were speedier in the early universe, it could account for the universe’s homogeneity.

“As soon as you raise the speed limit in the early universe,” Magueijo says, “you start being able to work on explanations for why the universe is the way it is.”

A finely tuned universe.

“Calorie restriction has been known to extend lifespan for a long time.” said Dr. Kennedy. “The DNA damage response is linked to aging as well. LOS1 may be connecting these different processes.”

A number of the age-extending genes the team identified are also found in C. elegans roundworms, indicating these mechanisms are conserved in higher organisms. In fact, many of the anti-aging pathways associated with yeast genes are maintained all the way to humans.

The research produced another positive result: exposing emerging scientists to advanced lab techniques, many for the first time.

A new approach to a once-farfetched theory is making it plausible that the brain functions like a quantum computer.

The mere mention of “quantum consciousness” makes most physicists cringe, as the phrase seems to evoke the vague, insipid musings of a New Age guru. But if a new hypothesis proves to be correct, quantum effects might indeed play some role in human cognition. Matthew Fisher, a physicist at the University of California, Santa Barbara, raised eyebrows late last year when he published a paper in Annals of Physics proposing that the nuclear spins of phosphorus atoms could serve as rudimentary “qubits” in the brain—which would essentially enable the brain to function like a quantum computer.

SRF Summer Scholars Program opens December 1st!


The SRF Summer Scholars Program offers undergraduate students the opportunity to conduct biomedical research to combat diseases of aging, such as cancer, Alzheimer’s, and Parkinson’s Disease. Under the guidance of a scientific mentor, each Summer Scholar is responsible for his or her own research project in such areas as genetic engineering and stem cell research. The Summer Scholars Program emphasizes development of both laboratory and communication skills to develop well-rounded future scientists, healthcare professionals, and policy makers. Students participating in the program will hone their writing skills via periodic reports, which are designed to emulate text scientists commonly must produce. At the end of the summer, students will have the opportunity to put all of their newly developed communication skills into practice at a student symposium.

MOJAVE, California — The world is at the start of a renaissance in supersonic and hypersonic flight that will transform aviation, but the effort will need steady commitment and funding if the United States wants to lead the way, congressional leaders and industry officials said at a forum late last month.

“What’s exciting about aerospace today is that we are in a point here where suddenly, things are happening all across the board in areas that just haven’t been happening for quite a while,” said former U.S. Air Force Maj. Gen. Curtis M. Bedke.

“There was a period where engine technology had just sort of stagnated — a point where all materials technology was going along at about the same pace,” Bedke added. “There just wasn’t much happening. But suddenly, in all sorts of areas that apply to aerospace, things are happening.” [NASA’s Vision of Future Air Travel (Images)].
