The big physics news this week was the announcement of the long-awaited results from the Planck missions -- and the news is not good for the BICEP2 collaboration: the Study Confirmed Criticism of BICEP2's original Big Bang Finding. They may have had space dust in their eyes. Researchers on the Planck mission say galactic dust could fully explain the much-ballyhooed observation announced to great acclaim in March -- or at least part of the possible signal that BICEP2 claimed was evidence for cosmic inflation.
You can read the technical paper here (PDF) if you're so inclined, but note the title terms this "intermediate results," because it's not the final word. The two teams now need to compare their data side by side and do a joint analysis. Naturally, the members of BICEP2 were disappointed, but at least one member took the news in stride. "Whatever that answer is, we will do our best to report the evidence," BICEP2's John Kovac told National Geographic.
There was a good deal of interesting commentary to supplement the news stories, including Sean Carroll (a.k.a. my Time Lord), who admitted, "It's not looking good for gravitational waves." Richard Easther concurred with that assessment: "The results are discouraging for anyone hoping the original BICEP2 announcement would survive." Over at Nautilus, Paul J. Steinhardt, one of the most outspoken critics earlier this year, summarized what he thinks is wrong with inflation theory and his view of the Big Bang.
Matt Buckley observed on Twitter: "Today Planck told us that the Universe likes to kick dust in our eyes. Way to act like the tough guy at the beach, Universe." So that faint plaintive whimper you hear could be the sound of Nobel Prizes in physics being put on hold. Per Caleb Scharf, The Biggest Cosmological Problem Is… …living in a place that makes doing cosmology hard. Philip Ball was more positive in The Guardian: Scientists got it wrong on gravitational waves. So what? "The team involved has been criticised for publishing results before they were peer reviewed. But this is what science is: debate, discussion, deliberation."
Gravitational Waves Can Play Stars Like an Instrument: Finding Hints of Gravitational waves in the stars. "Scientists have shown how gravitational waves—invisible ripples in the fabric of space and time that propagate through the universe—might be "seen" by looking at the stars. The new model proposes that a star that oscillates at the same frequency as a gravitational wave will absorb energy from that wave and brighten, an overlooked prediction of Einstein's 1916 theory of general relativity."

Bonus: Mitchell and Webb point out the obvious: the jet packs might be perfectly safe, but what about the people flying them?

Physicist Laura Mersini-Houghton Claims to Have Proven Mathematically That Black Holes Do Not Exist in a (not yet peer reviewed) paper on the arXiv. Naturally, skepticism abounds. “The [paper] is nonsense,” [Bill] Unruh said in an email to IFLS. “Attempts like this to show that black holes never form have a very long history, and this is only the latest. They all misunderstand Hawking radiation, and assume that matter behaves in ways that are completely implausible.” So rumors of black holes' death have been greatly exaggerated.
How to Build a Magnetized Piano Harp. Andy Cavatorta "mounted a caboodle of magnets onto a piano's frame. Once the magnets are activated, electromagnetic vibrations pull and release the piano's steel strings in a bloom of various pitches in harmonic succession. By doing this, Andy has managed to feather dust an instrument that was created many centuries ago and offer it a new sonic vocabulary by tapping into the piano's uncharted harmonics."

Journey Through the Brain: Multiphoton Microscopy. "It works by shining infrared radiation through tissue, where it is absorbed by fluorescent proteins that have been genetically added to cells. Sensors pick up the emitted fluorescent light and plot the location of fluorescing cells. By directing radiation to focal points at different depths, scientists can chart 3D structure. Repeating this technique over days and weeks allows the identification and monitoring of the wiring remodeling dynamics in the living brain."

At the last check in 1989, there was a difference of about 50 micrograms, which the Engineering and Technology Magazine explains is presumably down to chemical interaction with the atmosphere."
Design Like a Scientist. "The design “scientist” sees design as a process of empirical exploration, during which tweaks to a product are matched against changes in observed user behavior. If the changes are negative (less of the desired behavior), the designs are scrapped. If the changes are positive (more of the desired behavior), the designs are kept and built upon. It’s an iterative, evolutionary process."
