Cellphone app could help illegal immigrants

64 sqThis is going to be controversial:

A UC San Diego professor said he has developed a cell phone tool that may help guide illegal immigrants safely across the border.

Similar to the way hungry drivers can find a restaurant through the global positioning system devices in their cars and cell phones, illegal immigrants soon may be able to plot their ways across the treacherous border between the United States and Mexico.

“It shares some aspects of the GPS systems that people have in cars,” said Ricardo Dominguez, a professor of visual arts at UC San Diego. “It locates where you are in relation to where you want to go, what is the best way to get to that point and what you can expect when you reach the endpoint.”

Dominguez, an activist and artist, said the reason for developing the technology, which he calls the Transborder Immigrant Tool, is to keep people safe.

As many as 5,000 people in the last 15 years have died trying to cross the border.

Of vapor and violence: Do gasoline fumes fuel aggression?

gastoonHere’s the agenda for this item: I distinctly remember that when I was a kid, sometimes–not always–the smell of gasoline would get me what one would today call high. It’s been a long time since it had that effect on me, but I also remember looking forward to those visits to the gas station.

So for obvious reasons this post fascinated me:

A new study, published in the open access journal BMC Physiology, has shown that rats exposed to fumes from leaded and unleaded gasoline become more aggressive.

Amal Kinawy, from Cairo University, Egypt, examined the emotionally incendiary properties of gasoline in three groups of male rats, each exposed to either leaded-gas fumes, unleaded-gas fumes or clean air. As well as observing the animals’ behavior, she studied any resulting neurological and physiological changes. She said, “Millions of people every day are exposed to gasoline fumes while refuelling their cars. Exposure can also come from exhaust fumes and, particularly in the developing world, deliberate gasoline sniffing as a means of getting high”.

The research demonstrates that rats exposed to either kind of fuel vapor showed increased aggressive behavior, such as more time spent in belligerent postures and increased numbers of actual attacks, in comparison to the clean air group.

Can’t recall either of my parents remarking on any strange behavior on my part. Not because of that, anyway. The ever-traditional more research is needed to rush to assumptions about gasoline vapor’s effect on humans, but it’s one more thing to worry about.

Those hacked climate e-mails: Good scientists, poor conspirators

showSo many things can be said about the hacking of the East Anglia Climate Research Unit’s e-mails. If nothing else, it shows that the ground rules for scientific and scholarly communication are changing rapidly. The dubious ethics of hacking aside, should we expect science, especially on politically charged issues, to get done with the world looking over researchers’ shoulders? Could you do your job with hecklers in the room?

Island of Doubt has this to say:

What’s interesting is how rapidly the climate denial blogosphere has latched onto this as proof that the entire climatology community are in on a scheme to defraud the world. And why whoever the hackers are would think that this material was actually all that interesting in the first place. The hacking of the data is a worthwhile story, insofar as IT security goes, but the content is just plain banal. All we learn is that scientists are humans after all.

Science historian Spencer Weart comments:

The theft and use of the emails does reveal something interesting about the social context. It’s a symptom of something entirely new in the history of science: Aside from crackpots who complain that a conspiracy is suppressing their personal discoveries, we’ve never before seen a set of people accuse an entire community of scientists of deliberate deception and other professional malfeasance. Even the tobacco companies never tried to slander legitimate cancer researchers.

RealClimate makes the winning comment, IMO:

More interesting is what is not contained in the emails. There is no evidence of any worldwide conspiracy, no mention of George Soros nefariously funding climate research, no grand plan to ‘get rid of the MWP’, no admission that global warming is a hoax, no evidence of the falsifying of data, and no ‘marching orders’ from our socialist/communist/vegetarian overlords. The truly paranoid will put this down to the hackers also being in on the plot though.

Instead, there is a peek into how scientists actually interact and the conflicts show that the community is a far cry from the monolith that is sometimes imagined. People working constructively to improve joint publications; scientists who are friendly and agree on many of the big picture issues, disagreeing at times about details and engaging in ‘robust’ discussions; scientists expressing frustration at the misrepresentation of their work in politicized arenas and complaining when media reports get it wrong; scientists resenting the time they have to take out of their research to deal with over-hyped nonsense. None of this should be shocking.

Smart enough to hack, not sophisticated enough to appreciate the daily give-and-take of how science works–is that how we nonscientists are going to approach critical issues? Maybe we can do better than that.

‘Mirror of emotions’ to ‘rationalize’ online traders

rationalizer_highres3“Curb your enthusiasm” seems to be the message of a new gadget from Philips Electronics and the Dutch bank ABN AMRO. They decided to collaborate on the “Rationalizer” bracelet system “after research confirmed that day traders sometimes act irrationally because their actions are affected by their stress level and powerful emotions such as greed or .”

The Rationalizer consists of an “EmoBracelet” and an “EmoBowl” and incorporates sensors and signal processors designed by Philips. The EmoBracelet’s galvanic skin response sensor measures the level of emotional arousal in a similar way to a lie detector. The result is displayed on either the bracelet or the EmoBowl as a light display that intensifies and changes to reflect the wearer’s intensifying emotional arousal. At the highest emotional the display has a greater number of elements moving at higher speed, and the color changes to a warning red.

The video is pretty entertaining. Yes, it does look like a phildickian update of the old mood ring. And it’s not just for day traders willing to admit that they sometimes get carried away.

Senior Director at Philips Design Clive van Heerden said sensing was becoming more important in today’s digital world. He also believes there are many other possible applications, such as game controllers, intelligent cameras to interpret social situations, or even dating sites that enable you to tell who is attracted to you.

Also, you have to love the name of the division of the bank that worked on this device: the Dialogues Incubator.

Now that’s minimalism: Art with microbes

opheliaThe Microbial Art site features graphics created with fungi and bacteria. The dozen or so artists on display include Alexander Fleming, and the styles range from homey-sampler to fractal-abstract.  A set of aesthetic criteria hasn’t emerged yet, but I particularly like the pictured work:

Artist JoWOnder presents a pre-Raphaelite painting of Ophelia created with bacteria. The demise of the painting is filmed using time-lapse photography, showing a story of death and creation of new life. The colors and animation for ‘6 Days Goodbye Poems Of Ophelia’ were created in a laboratory at Surrey University UK with the help of microbiologist Dr. Simon Park. When displayed in 2010, this will be an outdoor video installation of Ophelia with poems submitted from the public. Composer Milton Mermikides will be producing a sound track based on the genetic code of bacteria that colonize the gut.
