Montreal airport laser pointer a serious safety risk
Transport Canada is trying to find out who has been pointing laser pointers at airplane pilots over the last few days.
There have been at least six instances recently where pilots landing at Montreal’s Trudeau airport have been distracted by a green laser pointer.
The device, which can be purchased for $100 and has a range of three kilometres, can blind airline pilots, so Transport Canada considers it a serious safety risk.

Infiniti fun of laser
As a laser physicist, I investigate Physics in and with lasers, and develop new type of lasers. But I have never own a laser myself, not even a laser pointer. Recently, I got one from Techlasers. It is a Infiniti II 95mW, comes together with a dragon case and a goggle. It is slim and light, and take two AAA batteries to power. The beam is very clean and nice.
What I tried to do first is to take laser photos, as those cool people did. But it quickly turns out not an easy task. 
I pointed the laser to my fish tank. Poor golden fishes, I hope they were not frightened. But apparently, they avoid the laser beam well. They didn’t show up in my photos at all. All of my photos were blurred, because I took photo with one hand while another hand holds the laser pointer. I guess to really get good pictures I need kind of tripod for both my camera and the laser.
What do you think is in the following photo?
It is a bath towel. Interestingly, it looks deep, but actually flat.
Later I tried to point to objects like cups and bottles, etc, which are common subjects of laser photography. But the results are not as good as I have hoped. I need to learn photography. 
I haven’t dare to point to sky or play outdoor yet, because I don’t know if there is any local regulation on usage of lasers.

Greek scientists use lasers to clean Acropolis
In the past two and a half thousand years, the temples of the Acropolis have suffered fire, bombing and earthquake. Now, scientists are trying to save them from a new modern enemy: pollution.
Standing on a hilltop at the centre of Athens, a city of 4 million people, the Acropolis’ elaborately sculptured stones have fallen prey to a film of black crust from car exhaust fumes, industrial pollution, acid rain and fires.
A team of Greek engineers and restorers are using an innovative laser technology system to clean the surface of the ancient monuments, uncovering colours and ornamentation hidden for decades.
DuPont: Laser technology speeds development of corn, soybeans
DuPont has unveiled an advanced technology the company said will transform seed research and considerably speed up the development of higher yielding corn and soybean varieties.
DuPont business Pioneer Hi-Bred introduced Laser-Assisted Seed Selection as the newest tool in its Accelerated Yield Technology (AYT) toolbox. The technology promises to increase the size and scope of the Pioneer breeding program five-fold in the next three years, said DuPont.
Laser-Assisted Seed Selection uses a 120-watt carbon dioxide laser to score a small slice from a seed to capture its genetic information while maintaining the seed’s viability for planting.

Laser gunship hits $30 million bulls-eye
The U.S. Air Force has awarded Boeing a new contract worth up to $30 million for the next phase of development on the Advanced Tactical Laser.
The ATL is a C-130H aircraft outfitted with a 12,000-pound high-energy chemical laser module that would be used as a weapon against ground targets. It’s the smaller sibling of the Airborne Laser, a highly modified 747 under development that packs a similar weapon but that would be used against ballistic missiles.

Laser acupuncture effective against headaches in children
The July 2008 issue of Pain, a prestigious peer-reviewed medical journal published by the International Association for the Study of Pain (IASP), featured a German study conducted by eight pediatric doctors and clinicians. The researchers attempted to determine whether or not laser acupuncture would prove effective in relieving the symptoms of chronic headaches in 43 children.

The German researchers concluded, “that laser acupuncture can provide a significant benefit for children with headache, with active laser treatment being clearly more effective than placebo laser treatment.”
