A Chile SETI interview | Bad Astronomy

Posted on by

seticl_logoI was interviewed by my friend, SETI- and astronomy enthusiast Lourdes Cahuich for the SETI.cl website. And, because the site is in Chile, it’s also en Español.

I talk a bit about how I got started in astronomy and outreach, why I love social networks, and why I’m so strongly anti-antivax.

Bonus: there’s an interview with an article about Frank Drake there too!

OMB Memorandum: Identifying Low-Priority Agency Programs

"Your agency is required to identify the programs and subprograms that have the lowest impact on your agency's mission and constitute at least five percent of your agency's discretionary budget. This information should be included with your FY 2012 budget submission, but is a separate exercise from the budget reductions necessary to meet the target for your agency's FY 2012 discretionary budget request."

World Science Festival: What if Physicists Don’t Find the Higgs Boson? | Discoblog

Posted on by

bigbang“It’s as if we’re fish who have suddenly discovered we’re in water,” said Nobel Laureate Frank Wilczek about the Large Hadron Collider. “The LHC is the device for ruffling up the waters so that we can see waves.”

Wilczek took part in a panel discussion at a World Science Festival event on Saturday. The discussion revealed a bit more about how physicists will do the ruffling and what waves they expect to see. Besides once again allaying doomsday fears, the panel discussed each detector in the LHC and how it will help them find the “cosmic molasses” we’re swimming in–what gives everything in the universe mass.

Their prime suspect is, of course, the Higgs Boson–the last animal in the Standard Model theory’s particle zoo–but what happens if the LHC can’t find it?

“My experiment is looking at the primordial soup, and we know it exists,” said Jennifer Klay, who helped to develop the detector for ALICE. “We have more job security.” By soup, she means quark-gluon plasma, a liquid-like substance made from proton and neutron innards.

The three-story-tall ALICE detector will first look at a smash-up between lead nuclei. She explains that a nucleus behaves very much like a liquid drop: “We’re taking two liquid drops, colliding them at very high energies, and trying to boil them into a steam, essentially, of quarks and gluons.” She won’t see the quarks and gluons directly, but will watch the process as they “condense” into more familiar protons neutrons.

The ATLAS and CMS detectors will hunt for the Higgs. In the same way that physicists can’t see quarks, they won’t directly observe Higgs. Instead, they will use the seven-story-tall ATLAS to pick through the particle spray from protons’ collisions in an attempt to sieve out four familiar particles: two electrons and two “fat” electron cousins called muons. Monica Dunford, an experimental high-energy particle physicist who helped bring the ATLAS detector into operation, calls this “a double needle in the haystack.”

Wilczek believes that experimenters will see these four particles in two to five years after the LHC is running at full speed.

“The worst scenario to me, is that the LHC completes the Standard Model and doesn’t do anything more,” Wilczek said. “That would be horrible. We would learn something very profound, but we would also learn that Nature is a tease.”

Dunford agreed with Wilczek, but added that, given the $6 billion price tag on the first machine, the LHC better find something. “We can’t say, ‘Gosh, we didn’t find anything? How about 20 billion?”

Possible naked eye comet on the rise | Bad Astronomy

Posted on by

If you’re an early riser in the mid-northern latitudes of our planet (and statistically speaking, the odds are good for the latter part), then there’s a comet you might want to check out.

Comet McNaught (C/2009 R1) is currently moving rapidly across the northern sky, and it’s just on the edge of being bright enough to see with your unaided eye. Over the next few days it may even get bright enough to see easily in dark skies.

comet_mcnaught_2009r1

This picture, taken by Ernesto Guido and Giovanni Sostero, shows the comet and its long tail. It’s a multiple exposure centered on the comet, which is why you see several star images for each star. You won’t get a view this nice (probably) with binoculars, but you should be able to spot the tail.

The CometChasing website provides a helpful map of the comet’s location over the next few days. On June 21 it’s pretty close to the bright star Capella (one of the brightest in the sky) but it’s not known how bright the comet will be by then. Also, McNaught reaches perihelion (closest point in its orbit to the Sun) on July 2/3, so it’ll be tough to see in a few weeks (though probably brighter; as they gets closer to the Sun most comets get much brighter, but their proximity to the Sun makes them very difficult to spot). With comets it’s always good to get them while the getting’s good. Go look now!

You can find more info on the Cometography site, a spectacular picture on APOD, and an interesting animated GIF showing the motion of the comet, too.

As a bonus for early risers, Jupiter and Uranus will have a series of close approaches to each other in the sky, so you can check that out as well.


Oil Spill Update: The President Gets Feisty, the Cleanup Will Take Years | 80beats

Posted on by

skimmerIf we’re lucky, BP’s relief wells will be done in August and the company’s all-time blunder will stop leaking. But even it that happens, the Coast Guard now concedes, it will take years to clean up this disaster.

“It’s the breadth and complexity of the disaggregation of the oil” that is now posing the greatest clean-up challenge, the commander, Adm. Thad W. Allen, said at a news conference at the White House [The New York Times].

The oil has now spread 46 miles from the original site of the Deepwater Horizon explosion, the National Oceanic and Atmospheric Administration now says, and has been found at a depth of more than 3,000 feet. That confirms the wide undersea plumes of oil; BP initially denied those existed. Admiral Allen said it’s time to think of this not as one spill, but rather as hundreds of thousands of little ones.

Meanwhile, more oil continues to enter the Gulf. BP says its containment dome is capturing 11,000 barrels a day, though the government’s revised estimation of the total flow rate was 12,000 to 25,000 barrels, and the flow would have increased when BP sheared off the top of the riser during the recent operation that put the cap in place.

And as the oil patches flirt with the coastline, slathering some spots and leaving others alone, residents who depend on tourism and fishing are wondering in the here and now how to head off the damage or salvage a season that’s nearing its peak [AP].

In those areas where oil has already made landfall, cleanup workers continue to slog away. But at least 75 in Louisiana have grown ill, including fisherman George Jackson.

“They didn’t supply us with nothing,” says Jackson. “Now they’re starting to disperse gloves and hazmat suits.” Chemicals and vapors, both from oil and dispersants, can pose serious health risks. They can inflame the nose, throat and lungs, and aggravate asthma. When absorbed in the bloodstream, oil compounds like benzene or toluene can cause headaches and dizziness and could have long term toxic effects on the brain, liver and kidneys after prolonged, direct contact [CBS News].

As all this goes on, President Obama continues to star in his weird rehash of The Queen. If you haven’t seen Helen Mirren’s Oscar-winning performance, she played Queen Elizabeth II during the weeks after Princess Diana’s death, when the British people demanded their sovereign show some emotion. There has been a similar groundswell in the U.S.—especially among its punditry—for the Prez to break his legendary cool and show some anger about the spill. This morning he obliged.

“I don’t sit around just talking to experts because this is a college seminar,” Obama told Matt Lauer. “We talk to these folks because they potentially have the best answers, so I know whose ass to kick” [USA Today].

Earthquake-Rocked Italian City to Seismologists: “This Is Your Fault.” | Discoblog

Posted on by

italy-earthquakeWhat if an unknown researcher predicts an earthquake using a disfavored technique? If an earthquake then happens and hundreds die, should naysayer scientists go to jail?

Some in the city of L’Aquila, Italy answered that odd question with a resounding yes. An April 6, 2009 earthquake that was predicted by Giampaolo Giuliani killed 308 people. Now the city’s prosecutors are considering charging seven researchers at the National Geophysics and Vulcanology Institute (INGV) and members of the city’s Major Risks Committee with manslaughter.

The prosecutors say the committee could be considered criminally negligent for telling the townspeople that there was no need to evacuate. A formal investigation has been opened, but charges haven’t yet been filed.

As reported in Life in Italy:

“Those involved were highly qualified individuals who should have provided the public with different answers,” said L’Aquila’s chief prosecutor, Alfredo Rossini. “It was not the case that we received no warning, because there had already been tremors. However, the advice given was that there was no need for people to leave their homes”.

Giuliani, the man who predicted the quake, works at the National Laboratories at Gran Sasso, though he has been misreported in both Italian and American media outlets as a physicist, seismologist, and a collaborator with the National Institute of Nuclear Physics. According to Science Insider, Giuliani’s work on earthquakes is a “hobby” and seismologists do not use the radon tests he cited, since statistically they have failed to accurately predict quakes.

Just Kick The Ball: The Scientific Secret to World Cup Penalty Shots | 80beats

Posted on by

ballIf you relax and concentrate, you’re more likely to make a goal. Seems pretty logical, but researchers at Britain’s Exeter University have tracked soccer players eye-movements to make sure. They have confirmed that players who ignore goalies’ distracting antics are more likely to make the shot.

The latest in the why-Britain-hasn’t-won-the-World-Cup-since-1966 line of research–which has also looked at the ball’s surface (smooth is good but some grooves necessary) and the psychological benefits of playing on your home field (it’s better)–Greg Wood’s study will appear in the Journal of Sports Medicine. Hopefully it will be available in time for the World Cup’s start on June 11th.

Wood says that goalies can make use of a biological instinct to screw up a kicker’s shot.

“We focus on things in our environment that are threatening. In a penalty kick, that threat is a goalkeeper,” Wood said. “If he (the goalkeeper) can make himself more threatening, he can distract the kicker even more. By doing (certain) behaviors, he can make it so the kicker will kick (the ball) near the goalie.” [AP]

The study tracked eighteen university-level players’ eye movements as they attempted penalty shots with varying levels of distraction from the goalie. It found that the players who lined up the shot, ignoring the chance that the goal-keeper might block it, were more likely to score.

Wood, a psychologist at the School of Sport and Health Sciences at the university, said the main problem was not skill but anxiety levels. “England definitely has a problem with this especially when compared to other teams such as Germany. While Germany wins 80 per cent of its penalty shoot outs, England loses 70 per cent. “If I was giving advice to the England team I would say pretend you are in a practise match, look at where you are going to hit the ball and aim it there. Totally ignore the goalkeeper. Even if he knows where the ball is going he is not going to get to it if it is well placed.” [Telegraph]

Anecdotal evidence has hinted at the same conclusion. Case in point: Bruce Grobbelaar’s 1984 European Cup goal-saving “spaghetti legs” shown in this video.

“The biggest memory I have is the 1984 European Cup final against Roma and my ’spaghetti legs’ routine during the penalty shootout that won us the trophy,” Grobbelaar said [as quoted in the study]. “People said I was being disrespectful to their players, but I was just testing their concentration under pressure. I guess they failed that test.” [ABC]

As also reported in The Telegraph, the study also concluded that teams that go first win sixty percent of penalty shootouts and that the best uniform color is red, “a dangerous and dominant colour in nature.”

Face In Space

Posted on by

I hope you all can do this, I am.

HOUSTON — NASA is inviting members of the public to send electronic images of their faces into orbit aboard one of the final remaining space shuttle missions.

Visitors to the “Face in Space” website can upload their portrait to fly with the astronauts aboard shuttle Discovery’s STS-133 mission and/or shuttle Endeavour’s STS-134 mission. Participants will receive special certificates from the Internet site once the mission is completed.

“The Space Shuttle Program belongs to the public, and we are excited when we can provide an opportunity for people to share the adventure of our missions,” said Space Shuttle Program Manager John Shannon. “This website will allow you to be a part of history and participate as we complete our final missions.”

To submit your image, visit: http://faceinspace.nasa.gov

Those without a picture can skip the image upload section, and NASA will fly their name.

Discovery and Endeavour’s missions are the final two flights remaining until the retirement of the space shuttle fleet. They are targeted to launch in September and November, respectively. For more information about the STS-133 and STS-134 missions, visit: http://www.nasa.gov/shuttle

Do Scientists Understand the Public? June 29–Mark Your Calendars | The Intersection

Posted on by

Recently, I learned that the American Academy of Arts and Sciences, with support from the Sloan Foundation, had undertaken a path-breaking project to examine what scientists understand about the public. The Academy held four sessions on the topic with experts over the past year and a half, and then asked me to write a paper about the workshops and what they taught and revealed. The initiative, and my paper, are scheduled to be unveiled at an event at the American Association for the Advancement of Science auditorium in Washington, D.C., on June 29, co-sponsored by the American Academy of Arts and Sciences and the Washington Science Policy Alliance. The event requires registration, and here is a write up for it:
While considerable attention has been paid to strengthening public education in science and technology, less effort has gone into helping researchers understand what lies behind the public response to new advances and discoveries. Public concerns about scientific developments can come not only from ignorance, but also from legitimate worries. In 2008, the American Academy of Arts and Sciences launched a study on what the scientific community knows or should know about the public and its concerns. Funded by the Alfred P. Sloan ...
