Growth Cocktail Helps Restore Spinal Connections in the Most Severe Injuries

Repairing damaged nerves in a rodent study marks a crucial first step toward bringing back lost movement

By Emily Willingham on August 30, 2018

In 1995 the late actor Christopher Reeve, who most famously played Superman, became paralyzed from the neck down after a horseback-riding accident. The impact from the fall left him with a complete spinal cord injury at the neck, preventing his brain from communicating with anything below it. Cases like Reeve’s are generally considered intractable injuries, absent any way to bridge the gap to restore disrupted communication lines.When Reeve died in 2004 a means of reconnection had yet to be built. Now, 14 years later, researchers have coaxed nerve cells to span the divide of a complete spinal cord injury. Their findings, described August 29 in Nature, are specific to only one kind of nerve cell and much work remains before a means of reconnection reaches patients, but the results make an impression. [...]

Their first effort failed. They tried dampening the activity of a gene called PTEN because the gambit had worked well with a few other types of nonspinal neurons. To their surprise, that strategy did not succeed with the propriospinal cells. They then turned to a set of chemicals that promote nerve cell growth and trigger production of a well-known structural protein called laminin, widely used in tissue engineering as a scaffold. Some of these growth promoters are active in embryonic development, and adults usually do not make them. Previous efforts to coax axons across an injury gap using so-called growth factors alone had come up empty—failures blamed on other inhibitory chemicals getting in the way.

The Amazon Forest


The Amazon is often called the lungs of the earth and produces 20% of the world’s oxygen. For this reason, many people are trying to stop deforestation in the rainforest. Brazil, for example, is working hard to help the rainforest survive.


A few years ago, the Brazilian government put forward a plan called ARPA (Amazon Region Protected Areas). It had the support of many international agencies, including the World Bank, and the German Development Bank, KfW. The main aim was to build new areas of protected rainforest, maintain areas of the rainforest that hadn’t yet been destroyed, and stop deforestation. Deforestation contributes greatly to global warming because carbon dioxide is released into the atmosphere when trees get cut down and burned.


One of the first areas to be recognized as part of ARPA was the Tumucumaque Mountains National Park. It is 38,800 km2 and is the same size as Switzerland, a small country in Central Europe. It’s the world’s largest protected tropical national park, and the second largest national park. It is home to certain species of jaguar, eagle, and lizard, which can only survive in the rainforest. Many of these species are under threat from climate change and deforestation.


In order to work in the park, conservationists need a reliable map. However, no map existed, and they didn’t have enough knowledge to make one on their own. They came up with the idea of involving local tribes to help them, combining modern and ancient methods to produce a map. The tribes learned to use global positioning system handsets (GPS), in conjunction with their local knowledge of the area, which included fishing and hunting grounds, and places of historical or mythical importance. Aerial photos were a 20useful aid in the process as well. This method of map-making is now the key to the future of rainforests, in Brazil and the rest of the world too.

What makes a school good? (Part II)

Another reason the schools may be so successful is the teachers. Teachers in Finland are seen as very important. They are well respected and the field of education is considered to be a science, with its own methodology, theory and principles. Every teacher studies for five years before they can teach. This is in contrast with the status of education in many other countries. Perhaps this explains why it's actually rather difficult to get a job as a teacher in Finland, as well as the reason that it's such a popular job.

In order to get students' opinions about what makes a school 'good', I visited my local school playground to do a little informal research. The thirteen-year-olds I spoke to were interested to hear about the Finnish schools. I asked them if they thought British schools were too strict and whether they thought more students would go to university if things were changed. Fay, one of the best students in her year, said she didn't think British students would benefit from a school that was too easy-going. She felt her teachers weren't strict enough, and that was why few students in her school went on to higher education.

So it seems that the Finnish education system has come up with a 'formula' that works successfully in that country. Their example can serve as a model for other countries, but each country will have to work hard to put together an education system that will meet the needs of its people.

In the sentence “The book begins by cataloguing the various components that typically comprise a nun's habit” (third paragraph), the word “that” is a pronoun used at the beginning of an adjective clause (a dependent clause that modifies a noun). Besides “that”, other English relative pronouns are “who” and “whose”.
Based on the information above and on formal grammar rules, choose the option that provides a sentence in which the relative pronoun is used correctly.
