A University of Tokyo group of researchers, led by bioengineer Shoji Takeuchi, has made an electronic sensor capable of smelling gases. The sensor uses genetically engineered frog cells. Since previous sensors were not very accurate, the scientist decided to try a biological approach. The invention was revealed in a US scientific journal yesterday, and is supposed to be used to design better machines to detect polluting gases in the atmosphere.

Previous smell sensors were based on quartz rods, which vibrate when a substance binds to them. The gases are distinguished by their molar masses, which can be similar for molecules with different structure, thus relatively often triggering a false positive. Trying to find a more accurate solution, Takeuchi decided to follow an example from insect world. As he explained, “when you think about the mosquito, it is able to find people because of carbon dioxide from the human. So the mosquito has CO₂ receptors. When we can (extract) DNA (from the mosquito) we can put this DNA into the frog eggs to detect CO₂.”

Genes of several insects (the silk moth, diamondback moth and fruit fly), injected into African clawed frog Xenopus laevis eggs, allowed them to produce relatively inexpensive and useful sensors. The choice of the species was caused by their widely studied and well-understood protein expression mechanism.

The modified cells responded to three kinds of pheromones and one odourant, which have similar chemical properties. When a molecule of an odorous substance adhered to the receptor on the membrane protein, ion channels opened for a certain period of time, and a current was generated. Its magnitude was clearly different for all four tested substances, allowing to distinguish between them accurately.

The colleagues embedded the sensor into a mannequin, so that it could shake its head when a gas was detected. It was easier to observe. Pheromones and molecules with quite similar molecule structure produced clearly distinguishable reaction, with higher accuracy than other biological or human-made sensors. As the research group said, the detection sensitivity of the odor sensor is several tens of parts per billion (ppb), and it is as high as the sensitivity of an existing odor sensor that uses an oxide semiconductor. The distinctive feature of the new sensor is its capability to selectively detect some odorous substances, rather than its sensitivity. Very few false positives were possible due to the biological mechanism involved.

At normal temperature, the sensor lifetime is about 12 hours, which can be extended by putting it into a refrigerator before first use.

Shoji Takeuchi says has a great hope for research use in future, since the frog eggs are very practical for genetic engineering, and can be conveniently used to develop smell sensors for a wide range of gases. He said, “The X. laevis oocyte has high versatility for the development of chemical sensors for various odorants. We believe that a shared ability to smell might open a new relationship between man and robot. .. The research will have wide implications… If the sensor is embedded in a nursing robot, it will be able to identify certain mouth odors or body odors. Also, it can be used for detecting CO₂, air pollution, water pollution and food. It’s very important for the environment.”

Wikinews reporter Iain Macdonald has performed an interview with Dr Isabella Margara, a London-based member of the Communist Party of Greece (KKE). In the interview Margara sets out the communist response to current events in Greece as well as discussing the viability of a communist economy for the nation. She also hit back at Petros Tzomakas, a member of another Greek far-left party which criticised KKE in a previous interview.

The interview comes amid tensions in cash-strapped Greece, where the government is introducing controversial austerity measures to try to ease the nation’s debt-problem. An international rescue package has been prepared by European Union member states and the International Monetary Fund – should Greece require a bailout; protests have been held against government attempts to manage the economic situation.

According to outgoing Massachusetts governor Mitt Romney, an explosion that was “equivalent to a 2,000 lb. bomb” and registered 0.5 on the Richter scale decimated an area of Danvers and is also a “Thanksgiving miracle.”

The explosion occurred around 2:45 am EST, this morning in the Danversport area of Danvers, Massachusetts at the plant for solvent and ink manufacturer, CAI Inc. The explosion, which was caught on security camera and was heard up to over 25-50 miles away in southern Maine and New Hampshire.

The explosion damaged over 90 homes, blowing out windows and knocking some houses off their foundations. Officials believe that some of the more extensively damaged houses will have to be leveled and rebuilt. Some of the buildings damaged included a bakery, boats at a close by marina and the New England Home for the Deaf, an assisted-living facility for people who are deaf or deafblind and elderly residents requiring constant care. “These people are extremely fragile,” said state Rep. Ted Speliotis, D-Danvers, whose district includes the affected area. “Many of them have Alzheimer’s and other illnesses. It’s clear they can’t stay here long, but it’s clear they won’t be able to return for quite a while.”

Danvers Fire Chief James P. Tutko toured the area by helicopter and said many residents would be kept from their homes for the foreseeable future. “It looks like a war zone, that’s the only thing I can say,” Tutko said. When asked about the loss of no life at all, he responded “Somebody out there likes us.” Finally, he said that finding out the cause of the explosion would take days.

Outgoing governor Mitt Romney toured the area and said the explosion was a “Thanksgiving miracle” as the explosion was “equivalent to a 2,000 lb bomb going off in a residential neighborhood,” and that no one was killed and only about 10 people suffered only minor injuries in area that included over 300 residents. Residents of the area have been evacuated to the Danvers High School where temporary shelter has been set up by the American Red Cross of Massachusetts Bay. Donations are being taken for residents affected by the explosion. Residents are also being told to start filing insurance claims right away and to keep track of their expenses for items bought.

There were minor environmental concerns due to water runoff of chemicals. According the Environmental Protection Agency‘s on-scene coordinator Mike Nalipinski, preliminary tests showed low levels of toluene, a solvent, but said it was nothing of significance. Water runoff from the water used by firefighters left a purple sheen on the river and tests were being conducted. However, the water is not a local drinking water supply and the chemical evaporates quickly. Chief Tutko said there was no risk of toxic fumes getting into the air.

An Eastern Propane facility was also located near the area, however, it was not the source of the explosion. A spokesman for the company said that although the property suffered some minor damage, their tanks are secure.

According to WHDH television, a person who answered the telephone at CAI’s Georgetown, Massachusetts headquarters refused comment, and a telephone message left at the company president’s home was not immediately returned.

Toronto pop culture convention Fan Expo Canada has wrapped for another year. It ran from Thursday to Sunday. Major panels included Tim Curry and the cast of Rocky Horror Picture Show, Beauty and the Beast voices Robby Benson and Paige O’Hara, actors Kathleen Turner, Richard Dreyfuss, Anthony Daniels, Felicia Day, and child leads from Stranger Things. Canadian television channel Space hosted a Star Trek: Discovery panel with seven lead cast members. On the heels of sister event Toronto Comic Con’s Degrassi reunion event, the lineup included a twentieth anniversary panel with the stars of another Canadian high school television series, Student Bodies.

Heading into its fourth and final season, attendees got a chance to see the season opener of Star Wars: Rebels on Saturday, followed by a panel. The event has had a continuing relationship with the series, screening other episodes previously. The second season premiere of the sci-fi series Travelers was accompanied by a panel including Eric McCormack. Canadian true-crime drama Bad Blood had its world premiere. Other debuts included broadcaster City with the Canadian premiere of Ghosted, with Craig Robinson in attendance, Teletoon with the Canadian premiere of Hotel Transylvania: The Series, and YTV with the new animated series Mysticons.

Anime fans could watch episodes of their favourite shows, including AKB0048, Otaku No Video, Hana Yamata, My Hero Academia, Fairy Tail, and Penguindrum.

The book Star Wars Made Easy, targeted to non-fans to get up to speed on the fictional universe’s various facts and figures, was ironically launched by DK Canada for a room of fans of the franchise. Author Christian Blauvelt answered questions from the audience on topics like his opinion on Midiclorians — he understands fan contention, but suggested that science and religion can co-exist, like in the real world — quizzed the audience on trivia, and signed copies of his book.

Some panels were quite ahead of the curve: one on Star Wars costume and prop building discussed building Porgs figures, despite the film The Last Jedi not being released to theatres yet.

York Regional Police were at the event with United and Unity, two brightly lit characters of their own creation. The force received funding in 2014 from the Provincial Anti-Violence Intervention Strategy to create a short film featuring the character United, receiving positive recognition locally. “Our United superhero program is part of our on-going efforts to connect with our community and show police in a different light,” YRP Constable Andy Pattenden told Wikinews. He explains that the officers who developed the project have a background in film-making, and “serve as an opportunity for us to start a conversation with youth and connect with them at a non-traditional level.”

Star Wars character Jabba the Hutt, a puppet in the 1983 film Return of the Jedi, was re-created by the 501st Legion as an animatronic. The 501st is a fan group that dresses like the series villains for charitable events, particularly those raising funds for the Make-A-Wish Foundation. The new addition to their annual display commanded long lineups throughout the day, from con-goers looking to donate in exchange for a photo-op with the massive, slug-like alien.

As with most major conventions, cosplayers were numerous, ranging from simple outfits that wouldn’t raise an eyebrow if worn from day-to-day, to elaborately-created costumes and giant props. Outfits recognized by Wikinews’ reporter ranged from classic characters like the 1960s version of Batgirl and Oswald the Lucky Rabbit, a character created by Walt Disney in 1927, before Mickey, to 2010s characters from creative works like Undertale, Disney Descendants, League of Legends, and Adventure Time. Few characters are too obscure, if they appeal to a fan: the female avatar of “hivemind” character Unity, from a single episode of Rick and Morty, was spotted. One woman “biting” another woman’s arm would be cause for concern most places, but at a pop culture convention, it simply means that “Lilo” is re-enacting a scene with “Mertle”, as seen in the film Lilo and Stitch.

Wikinews talked with Cheryl, the co-host of the weekly video series “Our Didnee Side”, who was dressed as Gadget Hackwrench, a mouse from the 1990s television series Chip ‘n Dale: Rescue Rangers. Speaking for both of the hosts, she said their passion for Disney has “exploded” since starting the YouTube channel, and that they are both “creators. We can’t seem to go a day without making something. We love doing Disney cosplay because it is like a beacon for other people in the fandom to come find us in a sea of other characters.” Conventions like Fan Expo Canada become “a great opportunity to meet like-minded Disney fans, and to possibly escape for the weekend from our ‘boring human’ lives.”File:FXC17 Stay Puft.jpg

Adrianna Prosser, host of Toronto geek culture community website Geektropolis, spent part of the convention Fan Expo Canada 2017 as the Stay Puft Marshmallow Man. She told Wikinews that “geeking in Toronto is always such a joy, what with amazing cosplay and passionate fandoms coming together at Fan Expo!” She explained that the site tries to keep the feeling of the event going all year, featuring local creators and “geeky” fans, in an effort to bring the community closer together.

Party game Cards Against Humanity — intriguingly available under a non-commercial Creative Commons license — offered a “Free Apologies from An American” booth, where a representative offered regrets to the largely Canadian visitors. The booth’s curtains came into use at least once on Friday, closing when a Trump cosplayer reached the front of the line.

Michael Gurian, psychologist and author of “What Could He Be Thinking?“, has claimed to identify approximately one hundred structural differences between male and female brains in a recent study. Gurian comments:

“Men, because we tend to compartmentalize our communication into a smaller part of the brain, we tend to be better at getting right to the issue, the more female brain (will) gather a lot of material, gather a lot of information, feel a lot, hear a lot, sense a lot.“

One major structural difference that Gurian has made clear is that males generally have more activity in the mechanical centers of the brain, while women have more activity in centers of the brain dedicated to verbal communication and emotion. A clear example of this is the hypothetical situation of giving a child a toy. He explains it as such:

“That doll becomes life-like to that girl, but you give it to a two-year-old boy and you are more likely, not all the time, but you are more likely than not to see that boy try to take the head off the doll. He thinks spatial-mechanical. He’s using the doll as an object.“

Another expert, Dr. Marianne Legato, says it all boils down to genetics, noting that the Y chromosome (which only males carry) has “at least 21 unique genes unique to males which control many of the body’s operations down to the level of the cells.”

Gurian agrees that culture is significant in brain development, but argues that biology plays an equally important role. He makes a point of how the MRI scans show that the female corpus callosum, the center of the brain which regulates communication between the brain’s hemispheres, is larger than the male’s. On the other hand, the scans also show that information flows more freely between the hemispheres of the male brain.

The exact role that brain structure plays in behavior, however, has been an area of considerable contention in science for literally hundreds of years. Early studies in craniometry conducted by Paul Pierre Broca were used to attempt to distinguish differences between human races, though have now been dismissed as scientific racism. The nature-nurture debate has raged for centuries in a variety of forms, without yet any clear resolution as to the role in which innate biological tendencies interact with environmental conditions or willed behavior. As such, studies relating to brain structure and claims to innate behavior often generate substantial controversy.

MIT anthropologist of science Joseph Dumit’s study of brain imaging in his book Picturing Personhood: Brain Scans and Biomedical Identity, noted that the apparent “transparency” of such pictures (the appearance that they can be easily interpreted by laymen, when they are often the source of ambiguity and dispute by even highly-trained neurosurgeons) has led to their proliferation as indicators of objective truth in media and in courts of law, and that such conclusions are often knowingly exaggerated by the specialists creating the images for better visual effect.

The timing of Gurian’s book comes on the heels of another controversy over gender differences sparked by comments made by Harvard president Lawrence Summers, who blamed low numbers of women in the sciences on genetic differences. Summers has been criticized by a large number of academics and scientists, as well as by many news publications, in the wake of what he was reported as saying during a conference on January 14.
