Is That Smartphone Making Your Teenager’s Shyness Worse?
The development of new technologies, especially computers and smartphones, has greatly changed people’s lifestyles. People can telework without going to offices, and shop online without wandering in stores. While this has brought about convenience, it has also generated many adverse effects. People tend to spend more time with their devices than with their peers. Parents of shy teenagers ask, “Is that smartphone making my teenager’s shyness worse?”
Professor Joe Moran, in his article in the Washington Post, says that the parents’ concern is reasonable. The Stanford Shyness Survey, which was started by Professor Philip Zimbardo in the 1970s, found that “the number of people who said they were shy had risen from 40 percent to 60 percent” in about 20 years. He attributed this to new technology like email, cell phones and even ATMs. He even described such phenomena of non-communication as the arrival of “a new ice age”.
Contrary to Professor Zimbardo’s claims, other findings showed that the new technology provided a different social method. As an example, teenagers often use texting to express their love without running into awkward situations. Texting actually gives them time and space to digest and ponder a response. Further, Professor Moran said that the claim of Professor Zimardo was made before the rise of social networks; shy teenagers can share their personal life online even if they don’t talk in public. He also talks about the paradox of shyness, where shyness is caused by “our strange capacity for self-attention”, while “we are also social animals that crave the support and approval of the tribe.” Therefore, new technologies are not making the shyness worse, in contrast social networks and smartphones can help shy teenagers find new ways to express that contradiction.

Biologists Propose to Sequence the DNA of All Life on Earth
You may think that it is impossible to sequence the DNA of all life on Earth, but at a meeting organized by the Smithsonian Initiative on Biodiversity Genomics and the Shenzhen, China-based sequencing powerhouse BGI, researchers announced their intent to start the Earth BioGenome Project (EBP). The news was reported in Science. There are other ongoing big sequencing projects such as the UK Biobank, which aims to sequence the genomes of 500,000 individuals.
The significance of the EBP will greatly help “understand how life evolves”, says Oliver Ryder, a conservation biologist at the San Diego Zoo Institute for Conservation Research in California. Though the EBP researchers are still working on many details, they propose to carry out this project in three steps. Firstly, they plan to sequence the genome of a member of each eukaryotic family (about 9000 in all) in great detail as reference genomes. Secondly, they would sequence species from each of the 150,000 to 200,000 genera to a lesser degree. Finally, the sequencing task will be expanded to the 1.5 million remaining known eukaryotic species with a lower resolution, which can be improved if needed. As suggested by EBP researchers, the eukaryotic work might be completed in a decade.
There are many challenges to starting this project. One significant challenge is sampling, which requires international efforts from developing countries, particularly those with high biodiversity. The Global Genome Biodiversity Network could supply much of the DNA needed, as it is compiling lists and images of specimens at museums and other biorepositories around the world. As not all DNA samples in museum specimens are good enough for high-quality genomes, getting samples from the wild would be the biggest challenge and the highest cost. The EBP researchers also need to develop standards to ensure high-quality genome sequences and to record associated information for each species sequenced. (Elizabeth Pennisi, ScienceInsider)
