Science, Technology and Engineering

Research in science, technology, and engineering is an exciting, dynamic career opportunity. This career affects every aspect of life, both today and in the future.
Scientific research leads to an improved quality of life. In the medical field, scientific research has led to a myriad of new medications, procedures, and non-invasive tests designed to accurately diagnose and treat conditions that were terminal only a generation ago. In the agricultural field, scientific research has led to improved farming techniques yielding healthier and more abundant crops. It has provided clean water to countless individuals and improved the quality of the air.

Is science ever wrong?

Science is a well-established way of testing ideas. Scientists have an idea, and then run an experiment to test it. Then they look at the result, to see if they correctly predicted what happened. In many fields of science, including medical science where consequences can be harmful, what happens is so complex it’s impossible to observe everything. To help make sense of it all, scientists use statistics.

Scientists run experiments to test new medicine. They do each experiment many times, recording their results. At the same time, they can run each experiment without the new medicine, instead using a fake treatment called a placebo, and they repeat this lots of times as well.

The links in genomes between humans and gorillas

gorillaThe human genome project was one among the most ambitious projects and a lot has been revealed from the results. A decade ago, a few scientists showed the world, the sequence of the entire human genome. Since the completion of this ardent project, scientists have been trying to unravel the genetic sequence of the apes- with whom we shared our ancestors some ten million years ago. After the successful completion of the gene sequence of the other apes like chimpanzee (which was published in the year 2005) and orangutan (published in 2011), gorillas now have their complete gene sequence analyzed.

The results reveal a close association between the human genome and that of the gorillas. The astonishing fact is that parts of the human genome share a higher degree of similarity with the genomes of the gorilla’s than that of the chimp’s. In fact, the gorillas share the same set of genes that highlight our unique evolutionary pattern. The genetic sequence analysed was that of a western lowland gorilla, a female, named Kamillah, who lives at the San Diego Zoo Safari Park. The DNA of other gorillas were also sequenced; that includes two more western lowland gorillas and one eastern lowland gorilla, which is a rare species. Read the full story

Canadian and Spanish researchers have discovered a new form of bacteria, called Halomonas titanicae, which is contributing to deterioration of the the world’s most famous shipwreck.

The discovery was made by researchers Henrietta Mann, Delahousie University (Canada), and Cristina Sánchez-Porro and Antonio Ventosa, University of Seville, in a “rusticle” hanging from the Titanic at a depth of four thousand meters.

“Rusticle” appears like a stalactite formations but is created by corrosion of the metal of the Titanic in the deep sea.

Dalhousie University along with other partners, stated the bacterium Halomonas titanicae seems to be responsible for the creation of “rusticles” wich accelerate corrosion of metal. Read the full story

Monitoring Software

The Internet can be tricky for parents to deal with because kids often need to use the Internet for school, but parents parents are often worried about the various activities that their children might be engaged in. Peer-to-peer file sharing can lead to lawsuits and even a criminal prosecution. Some teens might engage in activities online that are embarrassing to the family or may lead to viruses or hackers accessing the computer. Fortunately, there are various forms of monitoring software that can offer parental control.

Monitoring software can also be very helpful when parents are trying to learn what their children are up to, such as whether they are attending class or doing their homework.

Many teens use the computer purchased specifically for schoolwork to play computer games or chat with friends. Monitoring software can not only record activities on the computer, but smartphone software such as Mobile Spy can silently record the teen's GPS information, text messages and phone call information.

Monitoring software sits silently on a computer or mobile device and monitors all of the activities carried out on the device, encouraging the teen to consistently use the device for communication. Activity is usually uploaded to an online account so that the parent can monitor activity from anywhere without having to get close to the phone. This is crucial since parents will usually not have physical access to the phone without arousing suspicion.

Many monitoring programs also come with keystroke loggers, which log keys recorded on the computer, a contextual blocker, and features that allow parents to block certain websites. All of these features allow parents to have a peace of mind when allowing their teens to use the Internet.
