Pigeons Can Follow Abstract Number-Counting Rules

Trained pigeons demonstrate an ability to use abstract number-counting rules on par with primates and to recognize which groups of items contain more of those items. Sophie Bushwick reports

Several vertebrate species can distinguish between, say, two and five bananas?but with the exception of primates, they can?t grasp the numerical rules that would let them arrange their piles of fruit from least to most. Now, new research suggests that pigeons, like primates, can follow these abstract numerical rules. The study is in the journal Science. [Damian Scarf, Harlene Hayne and Michael Colombo, "Pigeons on Par with Primates in Numerical Competence"]
Researchers trained pigeons with cards on which were pictures of one, two or three shapes, sometimes in different sizes and colors. The birds were ultimately able to correctly pick a card with one large green square first, followed by a card with two small red ovals, followed by one showing three long blue rods.
Then, the pigeons demonstrated a new ability?faced with two cards each showing up to nine images, they could tell which card had more. Which indicates that they had an abstract understanding of the single-digit amounts. Rhesus monkeys trained in a similar way displayed the same talents. Whether this shared ability evolved independently or came from a common ancestor is unclear. But it is clear that birdbrains aren?t so dumb.

Scientists engineer mosquito immune system to fight Malaria

Researchers at the Johns Hopkins Malaria Research Institute have demonstrated that the Anopheles mosquito's innate immune system could be genetically engineered to block the transmission of malaria-causing parasites to humans. In addition, they showed that the genetic modification had limited impact on the mosquito's fitness under laboratory conditions. The researchers' findings are published December 22nd in the Open Access journal PLoS Pathogens.
In this study, Dimopoulos and his team genetically engineered Anopheles mosquitoes to produce higher than normal levels of an immune system protein Rel2 when they feed on blood. Rel2 acts against the malaria parasite in the mosquito by launching an immune attack involving a variety of anti-parasitic molecules. Through this approach, instead of introducing a new gene into the mosquito DNA, the researchers used one of the insect's own genes to strengthen its parasite-fighting capabilities.
According to the researchers, this type of genetically modified mosquito could be further developed and used to convert malaria-transmitting to Plasmodium-resistant mosquito populations. One possible obstacle for this approach is the fitness of the genetically modified malaria resistant mosquitoes, since they would have to compete with the natural malaria-transmitting mosquitoes. The researchers showed with their study that the Rel2 genetically modified mosquito strain lived as long, and laid as many eggs, as the non-modified wild type mosquitoes, thereby suggesting that their fitness had not become significantly impaired.
"Malaria is one of world's most serious public health problems. Mosquitoes and the malaria parasite are becoming more resistant to insecticides and drugs, and new control methods are urgently needed. We've taken a giant step towards the development of new mosquito strains that could be released to limit malaria transmission, but further studies are needed to render this approach safe and fail-proof," said Dimopoulos.

Train with Generic Tools in the Automotive Service Technician ...
?What I would like students to come in knowing what they want to do for a living,? says David Weatherhead coordinator and instructor in the Automotive Service Technician Apprenticeship Canadian Tire MAP 32 at Centennial College. ?If they know that they want to be automotive service technicians and they want to work for a Canadian company that?s progressive and has lots of business and opportunities across the country, that?s about the best things they can do. Ideally, I?d like them to be working with a Canadian Tire store. However, that?s not a necessity.? In addition, students applying to this undertaking must present at minimum an Ontario Secondary School Diploma or GED or equivalent. For this automotive service technician apprenticeship, candidates may apply directly to Centennial College. As space in the program is limited, acceptance is based on successful completion of all entry requirements. Successful applicants must obtain an employer and then register as a MAP apprentice with the Apprenticeship Branch of the Ministry of Training, Colleges and Universities.
?What makes this program unique is that it?s sponsored by Canadian Tire which gives us tools and equipment. Because they?re not automotive manufacturers they don?t give us vehicles or anything like that but tools and equipment and all of the resources they have to train the people in all the stores across the country,? Weatherhead says of the unique one-year automotive service technician training collaboration with Canadian Tire and its Associate Dealers, which employ 58,000 people and have 482 stores from coast-to-coast. ?Apprenticeship programs are so different from post-secondary programs in the fact that they?re very focused on a curriculum that is province-wide. It satisfies everyone at every level to be able to say they are getting what they need to be a licensed technician.?
The in-school portion of the automotive service technician apprenticeship is facilitated from Ashtonbee Campus, which is a fully-equipped transportation training centre. It is actually the biggest training centre of its sort in Ontario. During this time, students attend classes such as: Work Practices and Procedures, Engine Systems, Drivetrain Systems, Steering, Suspension & Brake Systems; Electrical, Electronics & Fuel Systems and more.
Meanwhile, the four offered weeks of on the job training gives students the opportunity to face real life scenarios, apply what they have learned, network and gain insight into the industry from seasoned professionals.
Canadian Tire offers customers a large selection of national and retail brands through three specialty categories in which the organization is the market leader ? automotive parts, accessories and service; sports and leisure products; and home products. Also offered are automotive services such as engines fixes, brake changes, windshield wipers and fluid level checks, and muffler, hose, belt and plug replacements. Essentially, if a repair is needed, it?s up to Canadian Tire technicians who have attended an automotive service technician apprenticeship to find a way to get it done.

Award-winning Japanese director Morita dead at 61 (omg!)
TOKYO (AP) ? Director Yoshimitsu Morita, whose films depicted the absurdity and vulnerability of everyday life in conformist Japan, has died. He was 61.
Morita, who won international acclaim over his prolific 30-year career, died Tuesday of acute liver failure at a Tokyo hospital, said Yoko Ota, spokeswoman at Toei Co., the film company behind his latest work.
Morita's movies were distinctly Japanese, depicting the fragile beauty of the nation's human psyche and visual landscape while daringly poking fun at its ridiculous tendency for rigid bureaucracy and ritualistic hierarchy.
Morita made a splash among global film buffs with 1983's "Family Game," starring Yusaku Matsuda of "Black Rain" as an offbeat tutor who forms a heartwarming relationship with a young man in a stereotypical middle-class family.
Its striking cinematography, focusing on rows and rows of identical apartments and people dining solemnly sitting side by side, was an exhilarating parody of Japanese family values.
His works were shown at many international film festivals, including Berlin and Montreal.
They included "Tsubaki Sanjuro," a 2007 remake of the 1962 classic by Akira Kurosawa, as well as works based on novels such as Soseki Natsume's poetic "Sorekara" and Junichi Watanabe's "Shitsurakuen."
"Bokutachi Kyuko A Ressha de Iko," a comedy about train lovers starring Kenichi Matsuyama of Tran Anh Hung's "Norwegian Wood," will be released posthumously next year, Toei said Wednesday.
Funeral arrangements were still undecided. Morita is survived by his wife Misao.
