The Runner’s High: A New Look at the Cause

Have you ever heard someone say they are addicted to working out, or running? For some this may be an odd statement since not all of us find workouts enjoyable. The truth is, is that you can feel a type of high from an intense workout and scientist have a new theory on the cause. Originally it was thought that the release of endorphins is what caused the euphoric feeling achieved through an intense workout, which reduced your body’s feeling of pain and so you would get the high feeling. Scientists now think that the high is caused by a...

30% of Spaniards believe Humans lived with Dinousaurs

A recent study has shown that Spain has a very low level of science knowledge. 30% of Spanish people believe that humans lived with dinosaurs. In fact, the dinosaurs died out 65 million years before humans appeared on earth. 25% of the population believe that the sun rotates around the earth. In fact, it is the earth that orbits the sun. The study interviewed 6,355 individuals from every part of the country. It also found that only 25% of Spaniards are interested in science. Most of the people interviewed say that they have no interest in science because they don’t understand it. Source of information: Antena 3 (in...

What Happens to Ants in Space?

Ants were sent to the International Space Station in January 2014 so that scientists could observe them when there is no gravity. Scientists wanted to know how the ants would work as a team without gravity. They gave the ants a new area to search and watched how they did it. Sometimes when an ant started to float, he grabbed onto another ant to climb back to the floor. Scientists did the same experiment on earth to see the difference. The ants in space searched the area much more slowly than the earth ants. This is only because they kept falling off the surface. Their behavior did not change. The scientists did the experiment to learn about co-operative methods without gravity. They want to use the ants’ technique for groups of robots. Check your vocabulary here: to observe (v), gravity (n), to float (n), to grab onto (v), to climb (v), behavior (n), co-operative (adj). Story and Photo:...

Ebola virus is changing and becoming more dangerous

Vocabulary: to mutate (v), form (n), contagious (adj), blood sample (n), cure (v+n), vaccine (n), symptoms (n), to pass on (phrasal verb), to track (v), spread (n+v). Scientists who are studying the Ebola virus have said that it is mutating: the virus is changing its form. They are investigating whether the virus is more contagious than last year. Blood samples are being sent to France in order to study this. Ebola is a virus that is similar to HIV and Influenza (the flu): these types of viruses mutate rapidly; any cure or vaccine we have will not work on the new mutation. The fear is that Ebola has mutated so that some people who have the virus don’t show symptoms; they don’t look or feel ill at all. However, they are still contagious and pass the virus on to other people. Because they don’t show symptoms, it is more difficult to track the development and spread of the virus. Currently the survival rate of Ebola is 40%. The research in France will hopefully give scientists a clear reason as to why some people survive the virus and others don’t. They also hope to develop a vaccine against...

2014: the hottest year on record

Vocabulary: rainfall (n), to suffer from (v), drought (n), greenhouse gases (n), vocal (adj), anomaly (n). Last year was the warmest year since records began. The temperature was especially higher in the ocean, Europe and Australia. However some parts of the USA were colder than previous years. All in all, the planet in 2014 was the hottest that it has been since people started recording global temperatures in the late 19th century. There were also many extreme weather events in 2014. For example, Guelmim, a town in the south of Morocco, received a year’s rainfall in just four days and Japan had the most rainfall it has ever had. On the other hand, certain parts of the USA, China and Central-South America did not get any rain and suffered from droughts. Bob Ward, from the Grantham Research Institute on Climate Change at the London School of Economics says that this is evidence that the increase in greenhouse gases in the atmosphere is causing the climate to change. The BBC reports that a “small but vocal” number of people deny this and that these results are anomalies. There is a UN Climate Summit in Paris at the end of the year. Many people believe that these statistics prove the existence of Climate Change and might influence heads of state into reducing emissions. Taken...
