Would it be wrong to eradicate mosquitoes?
The mosquito is the most dangerous animal in the world, carrying diseases that kill one million people a year. Now the Zika virus, which is carried by mosquitoes, has been linked with thousands of babies born with brain defects in South America. There are 3,500 known species of mosquitoes, but only the females from just 6% of species draw blood from humans - to help them develop their eggs. Of these, just half carry parasites that cause human diseases.
More than a million people, mostly from poorer nations, die each year from mosquito-borne diseases, including Malaria, Dengue Fever and Yellow Fever. Some mosquitoes also carry the Zika virus, which was first thought to cause only mild fever and rashes. However, scientists are now worried that it can damage babies in the womb. There’s a constant effort to educate people to use nets and other tactics to avoid being bitten. But would it just be simpler to make an entire species of disease-carrying mosquito extinct?
In Britain, scientists at Oxford University and the biotech firm Oxitec have genetically modified (GM) the males of Aedes aegypti - a mosquito species that carries both the Zika and Dengue viruses. These GM males carry a gene that stops their offspring from developing properly. This second generation of mosquitoes then die before they can reproduce and become carriers of disease themselves.
So are there any downsides to removing mosquitoes? Mosquitoes, which mostly feed on plant nectar, are important pollinators. They are also a food source for birds and bats while their young - as larvae - are consumed by fish and frogs. This could have an effect further ahead in the food chain. Mosquitoes also have limited the destructive impact of humanity on nature. Mosquitoes make tropical rainforests, for humans, virtually uninhabitable. Rainforests are home to a large share of our total plant and animal species, and nothing has done more to delay man-made destruction over the past 10,000 years than the mosquito.

How Brazil Crowdsourced a Pioneering Law
The passage of the Marco Civil da Internet, an “Internet bill of rights” commonly referred to in English as the Brazilian Civil Rights Framework for the Internet, demonstrates how the Internet can be used to rejuvenate democratic governance in the digital age. The law is important not only for its content, but for the innovative and participatory way it was written, bypassing traditional modes of legislation-making to go directly to the country’s citizens. At a moment when governments of all kinds are viewed as increasingly distant from ordinary people, Brazil’s example makes an argument that democracy offers a way forward.
The pioneering law was signed in 2014 and has three components. First, it safeguards privacy by restricting the ability of private corporations and the government to store Internet users’ browsing histories. Second, it mandates a judicial review of requests to remove potentially offensive or illegal material, including content that infringes copyrights. And third, it prohibits Internet service providers from manipulating data transfer speeds for commercial purposes. The bill was acclaimed by activists as an example the rest of the world should follow.
What makes this law even more interesting is that it became one of the largest-ever experiments in crowdsourcing legislation. The law’s original text was written through a website that allowed individual citizens and organizations — including NGOs, businesses, and political parties — to interact with one another and publicly debate the law’s content. This process was markedly different from the traditional method of writing bills “behind closed doors” in the halls of Congress, a process that favored well-connected families and large corporations.
Policymakers in other countries have tried to capture citizen input using social media before, but never on this scale, in a country of roughly 200 million people. Whether it would succeed was far from certain. During the website’s public launch, in 2009, one of the government lawyers summed up the organizers’ high hopes: “This experience could transform the way we discuss not just legislation about the Internet, but also the way we discuss other bills in Brazil, and, in so doing, reconfigure our democracy.”

This migrant crisis is different from all others
2015 was unquestionably the year of the migrant. The news was dominated for months by pictures of vast crowds shuffling through the borders of yet another European country, being treated with brutality in some places and given a reluctant welcome in others.
When researching a report for radio and television about the migrant phenomenon, it is possible to realize that there was nothing new about it. For many years, waves of displaced and frightened people have broken over Europe again and again and the images have been strikingly similar each time.
In 1945, __________ (1) the ethnic Germans, forced out of their homes in Poland, Czechoslovakia and Russia and obliged to seek shelter in a shattered and divided Germany. More recently, we can see floods of Albanian refugees escaping from the ethnic cleansing of the Serbian forces in Kosovo in 1998 and 1999.
Yet there is one major difference between these waves of migrants in the past and the one we saw in 2015. Professor Alex Betts, director of the Refugee Studies Centre at Oxford University says that it was the first time Europe faced people coming in from the outside in large numbers as refugees. He explains: “The fact that many are Muslims is perceived as challenging Europe’s identity.” European societies are changing very fast, indeed, as a result of immigration. In London, for instance, more than 300 languages are now spoken, according to a recent academic study. The influx of migrants reinforces people’s sense that their identity is under threat.
But how can the world deal conclusively with the problem? The former UN under-secretary-general for humanitarian affairs, Sir John Holmes, blames global governance. “Other powers are rising,” he says - Syria is an example of this. “And the United States doesn’t have the influence it once did, so the problem’s not being fixed, no-one’s waving the big stick and we’re having to pick up the pieces.” We have endured an entire century of exile and homelessness and the cause is always the same - conflict and bad government. Unless these are dealt with, the flow of migrants will never be stopped.

Hard Lesson in Sleep for Teenagers
By Jane E. Brody October 20, 2014
Few Americans these days get the hours of sleep optimal for their age, but experts agree that teenagers are more likely to fall short than anyone else.
Researchers report that the average adolescent needs eight and a half to nine and a half hours of sleep each night. However, in a poll taken in 2006 by the National Sleep Foundation, less than 20 percent reported getting that much rest on school nights. With the profusion of personal electronics, the current percentage is believed to be even worse. A study in Fairfax, Va., found that only 6 percent of children in the 10th grade and only 3 percent in the 12th grade get the recommended amount of sleep. Two in three teens were found to be severely sleep-deprived, losing two or more hours of sleep every night. The causes can be biological, behavioral or environmental. The effect on the well-being of adolescents — on their health and academic potential — can be profound.
Insufficient sleep in adolescence increases the risks of high blood pressure and heart disease, Type 2 diabetes and obesity, said Dr. Owens, pediatric sleep specialist at Children's National Health System in Washington. Sleeplessness is also linked to risk-taking behavior, depression, suicidal ideation and car accidents. Insufficient sleep also impairs judgment, decision-making skills and the ability to curb impulses, which are "in a critical stage of development in adolescence," Dr. Owens said. With the current intense concern about raising academic achievement, it is worth noting that a study by Kyla Wahlstrom of 9,000 students in eight Minnesota public high schools showed that starting school a half-hour later resulted in an hour's more sleep a night and an increase in the students' grade point averages and standardized test scores.
When children reach puberty, a shift in circadian rhythm makes it harder for them to fall asleep early enough to get the requisite number of hours and still make it to school on time. A teenager’s sleep-wake cycle can shift as much as two hours, making it difficult to fall asleep before 11 p.m. If school starts at 8 or 8:30, it is not possible to get enough sleep. Based on biological sleep needs, a teenager who goes to sleep at 11 p.m, should be getting up around 8 a.m.
Adding to the adolescent shift in circadian rhythm are myriad electronic distractions that cut further into sleep time, like smartphones, iPods, computers and televisions. A stream of text messages, tweets, and postings on Facebook and Instagram keep many awake long into the night.
Parents should consider instituting an electronic curfew and perhaps even forbid sleep-distracting devices in the bedroom, Dr . Owens said. Beyond the bedroom, many teenagers lead overscheduled lives that can lead to short nights.
Also at risk are many teenagers from low-income and minority families, where overcrowding, excessive noise and safety concerns can make it difficult to get enough restful sleep, the academy statement said. Trying to compensate for sleep deprivation on weekends can further compromise an adolescent's sleep-wake cycle by inducing permanent jet lag. Sleeping late on weekends shifts their internal clock, making it even harder to get to sleep Sunday night and wake up on time for school Monday morning.

Additional Factors That Affect Sleep Comfort
By Richard A. Staehler, MD
The type of mattress one uses is not the only factor for patients with pain and sleep difficulty. Many other factors need to be considered that may affect sleep, including;
- medication side effects;
- irregular sleep patterns;
- caffeine/alcohol/tobacco use;
- sleep apnea;
- anxiety/stress.
If comfort is not the only thing making sleep difficult, it is advisable for the patient to consult his or her family physician to discuss other possible causes and treatments for sleeplessness.
If anyone experiences significant or persistent back pain, there may be an underlying back condition that has nothing to do with the mattress. It is always advisable for people with back pain to consult with a health care provider for a thorough exam, diagnosis, and treatment program.
As a reminder, sleep comfort is first and foremost a matter of personal preference. No one should expect that switching mattresses or beds will cure their lower back pain, and changes in the type of bed or mattress used should be made solely for the sake of comfort,
