Teen Texting: Girls versus Boys

By Victoria Stern 

A new study from the American Psychological Association evaluated how 211 girls and 192 boys communicated via text and found notable gender differences in overall behavior and compulsive use:

• Teenage girls use texting for social connection, whereas boys mostly use it to convey information.

• Boys and girls send about the same number of texts every day, but girls are more likely to become compulsive texters.

• Teenage girls who compulsively text see a steeper decline in their grades than their compulsive male counterparts. The researchers suggest the social content of girls' messages may be more likely to distract them from their academic tasks.

• Compulsive texting also appears to affect girls' mental health more than boys', perhaps because girls are more prone to text about negative feelings and to ruminate on those feelings.

                       Frankentissue: printable cell technology

      In November, researchers from the University of Wollongong in Australia announced a new bio-ink that is a step toward really printing living human tissue on an inkjet printer. It is like printing tissue dot-by-dot. A drop of bioink contains 10,000 to 30,000 cells. The focus of much of this research is the eventual production of tailored tissues suitable for surgery, like living Band-Aids, which could be printed on the inkjet.

      However, it is still nearly impossible to effectively replicate nature’s ingenious patterns on a home Office accessory. Consider that the liver is a series of globules, the kidney a set of pyramids. Those kinds of structures demand 3D printers that can build them up, layer by layer. At the moment, skin and other flat tissues are most promising for the inkjet.

Houston’s Poor Neighborhoods Could Be Prime Zika Real Estate

The World Health Organization (WHO) has warned of the potential for the explosive spread of the Zika virus through the Americas. Margaret Chan, the director of the WHO, advised that the Americas could be hit by 4 million cases of Zika this year. The outbreak of Zika virus now centered in Brazil has been linked to a sudden increase in severe birth defects including microcephaly, babies born with smaller heads and brains. The National Public Radio – USA (NPR) recently reported that other neurological problems, such as babies born blind, may also be linked to Zika. Researchers do not fully understand Zika or have not yet proven causality, but the circumstantial evidence connecting the Zika outbreak to the sudden, large increase in birth defects is very strong.

Reports quoted experts who said that Zika was a low risk to the United States because the U.S. doesn’t have the poverty and high population densities that have caused the explosive spread of Zika in Brazil. However, Dr. Peter Hotez, a tropical disease researcher who lives in Texas, has warned that poverty and high population density makes Houston highly vulnerable to a Zika outbreak. He warned that the whole Mexican Gulf coast is already sufferingfrom increasing levels of tropical diseases spread by mosquitoes, in particular dengue fever. Because Zika virus is related to dengue fever and has the same mosquito vector, the expansion of dengue in the Gulf coast region is a good indicator of the potential spread of Zika virus
