'Sweaty' Billboard Kills Mosquitoes To Fight Zika Virus
The Mosquito Killer Billboard mimics human sweat to attract and destroy virus-carrying mosquitoes in Brazil. Continue reading →
In the global battle to stop the devastating Zika virus from spreading, the mosquitoes that carry it are proving to be an infatigable foe.
Enter the Mosquito Killer Billboard, a new open-source project in Brazil that targets the mosquitoes known to carry Zika, reports BBC News.
The billboard works by mimicking human breath to fake out the mosquitoes. A device inside sprays a combination of carbon dioxide and lactic acid solution. At night, fluorescent lights increase the attraction. Then mosquitoes get trapped in the display, later dying from dehydration, according to the project.
Since the mosquitoes the billboard targets fly around four feet high, the trapping mechanism is located at that height. It can attract the insects from a distance of up to around 1.5 miles, the Mosquito Killer Billboard site says. The Brazilian project was created by the ad agencies NBS and Posterscope.
The Zika virus causes a birth defect called microcephaly, a condition where babies are born with abnormally small heads and brains. Initial outbreaks occurred in Africa, Southeast Asia, and the Pacific Islands, the CDC reported. Last year infections were confirmed in Brazil. In February, the World Health Organization declared Zika a global emergency. An estimated two billion people are now at risk.
A mosquito with distinctive white markings called Aedes aegypti, also known as the yellow fever mosquito, carries Zika.
"The thing about this mosquito is that it's a flying bioterrorist menace," Edimilson Migowski, chief of infectious diseases at the Federal University of Rio de Janeiro, says in a video about the new billboard. He warns that if we don't stop it, the mosquito could take over the world.
Blueprints and technological details for the billboard are available online through a Creative Commons license, which means any city in Brazil or the world could create one. See how it works here:
You might have already spotted the big problem with the billboard, especially after watching that video. Probably not wise to place a mosquito-attracting billboard near bus stops or busy intersections where lots of people gather.
Ideally Mosquito Killer Billboards could be placed on the edges of populated areas, drawing the mosquitoes away from vulnerable crowds. If a sweaty fake-out is going to do the trick, we're going to need some really big signs.
Rarely has anyone looked at a potentially fatal infectious disease and exclaimed, "Now, that is a thing of beauty." One sculptor, however, has taken bacteria and viruses from their invisible world and placed them in ours.
Artist Luke Jerram has created a collection of glass artwork in the shape microorganisms -- bacteria and viruses no less that have the potential to infect or even kill human beings. By bringing these microscopic marauders to the light, Jerram demystifies these otherwise unknowable microorganisms. And using glass as a medium reinforces not only the fragility of the work, but also our own in the face of these diseases.
In this slide show, take a closer look at some of the highlights from Jerram's glass microbiology collection.
Turning HIV into a work of art is a seemingly impossible task. The virus is responsible for the deaths of an estimated 34 million people worldwide since the epidemic was first reported in 1981, according to UNAIDS, the joint United Nations Programme on HIV/AIDS.
The HIV virus sculpture was the first Jerram built for his collection.
If there's one disease that has plagued humankind throughout its history, it's malaria. In 2010, the World Health Organization estimated that more than 200 million people were infected with the disease, mostly in poverty-stricken regions of sub-Saharan Africa, but also parts of South America and Southeast Asia.
Malaria is transmitted through mosquito bites. Mosquito nets, insect repellant and pesticides are all effective means of prevention, but only for those with the available resources and access to afford them.
Looking at this spindly sculpture might make you the slightest bit queasy, and for good reason. E. coli is represented by this glass artwork. Although most E. coli strains are in fact harmless to humans, the strains we're most acquainted with are the ones that cause food poisoning.
This alien-looking sculpture is actually T4 Bacteriophage, a virus that targets E. coli bacteria.
Bacteriophages are small viruses that attach to the cell membrane of bacteria. The virus injects its DNA into the bacteria, which then produces replicas of the virus, filling the bacterium until it bursts.
If this model is giving you that nostalgic feeling of plagues past, you might not be surprised to find out that this work represents Severe acute respiratory syndrome, or SARS.
SARS made global headlines in 2003 when people in 37 countries and nearly reached pandemic levels. Although coverage of the illness was widely criticized for overstating the threat, nearly 9,000 were infected with the disease, with had a nearly 10 percent fatality rate.
Swine flu, shown here, was another contagious disease that drew global attention that Jerram selected for his exhibition, but this time it was personal. According to his website, Jerram came down with swine flu and constructed the sculpture "with a fever whilst swallowing my Tamiflu tablets every few hours."
Swine flu, or H1N1 strain of the influenza virus, made global headlines in 2009 as the next potential major flu epidemic. Though common among pigs, swine flu is rarely transmitted among humans. When it does infect a human, however, the symptoms associated with the virus, typical of other flu strains, are particularly acute.
Given just how common the Human Papilloma Virus (HPV) is among humans, you'd think this virus, pictured here, wouldn't be so controversial. In fact, it isn't, but the use of a vaccine to prevent the infection, which can lead to certain kinds of cancers in women.
Because the virus can be transmitted sexually, however, the idea of vaccinations, particularly compulsory ones for children -- the vaccine is in fact intended only for people 25 and younger -- generated a considerable pushback, despite the obvious benefits of the treatment.
Hand, foot and mouth disease might not get a lot of press, but these disease outbreaks are in fact fairly common, particularly among infants and children. Occasionally, they can be fatal. Symptoms are similar to the flu, with the exception of sores that can appear all over the body, but particularly the hands, feet and mouth of the carrier.
This final entry is an unrealized future mutation for a disease that doesn't exist yet. Look for it in a contaminated water main, food source or loving pet near you. (But seriously, don't.)
