ANN ARBOR, Mich.— A study links low vitamin D in young girls with early menstruation, which is a risk factor for a host of health problems for teen girls as well as women later in life.
Researchers from the University of Michigan School of Public Health measured the blood vitamin D levels in 242 girls ages 5-12 from Bogota, Colombia, and followed them for 30 months. Girls low on vitamin D were twice as likely to start menstruation during the study than those with sufficient vitamin D, said epidemiologist Eduardo Villamor, associate professor in the U-M SPH.

*Despegar-Decolar Sites Ranks as Top Online Travel Destination*
Bogotá, Colombia, August 11, 2011 – comScore, Inc., a leader in measuring the digital world, today released the latest results from a study on the online travel market in Colombia. The study found that in the past year visitation to the Travel category increased 25 percent to reach 3.2 million unique visitors in Colombia, as more online users utilized the web to research and purchase travel. Despegar-Decolar Sites led as the top travel destination in Colombia reaching 453,000 unique visitors in June, followed by Expedia Inc. and Avianca.com.
“Nearly 1 in 4 online users in Colombia visited a travel site in June,” said Alejandro Fosk, comScore senior vice president for Latin America. “Travel sites have witnessed rapid visitor growth in the past year as more consumers embrace the online channel for their travel needs while brands continue to improve the user experience by upgrading site features. Given that more mature online markets around the globe see upwards of half of their online population frequenting travel sites, there is much potential for continued growth in Colombia’s online travel sector.” (more…)
A small male bird called a golden-collared manakin performs a difficult, elaborate, physically demanding courtship dance. In new research, life scientists report that female golden-collared manakins select mates based on subtle differences in motor performance during these dances.
“The male jumps like he’s been shot out of a cannon,” said study co-author Barney Schlinger, professor and departmental chair of integrative biology and physiology and a professor of ecology and evolutionary biology at UCLA. “It’s exquisite. He sails like an acrobat and lands perfectly on a perch, like a gymnast landing a flawless dismount. Not only is there power to his muscle contractions but incredible speed as well.”(more…)
It’s not just how free the market is. Some economists are looking at another factor that determines how much a country’s economy flourishes: how smart its people are. For a study published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science, researchers analyzed test scores from 90 countries and found that the intelligence of the people, particularly the smartest 5 percent, made a big contribution to the strength of their economies.
In the last 50 years or so, economists have started taking an interest in the value of human capital. That means all of the qualities of the people who make up the workforce. Heiner Rindermann, of the Chemnitz University of Technology, wanted to look more closely at human capital, and particularly the factor that psychologists call cognitive ability. “In other words, it’s the ability of a person to solve a problem in the most efficient way—not with violence, but by thinking,” Rindermann says. He wrote the new study with James Thompson of University College London. (more…)
A rose by any other name would smell … like celery?
North Carolina State University research intended to extend the “vase life” of roses inserts a gene from celery inside rose plants to help fight off botrytis, or petal blight, one of the rose’s major post-harvest diseases.
Some fungal pathogens, the bad guys that infect plants, produce a sugar alcohol called mannitol that interferes with the plant’s ability to block disease like petal blight, which produces wilty, mushy petals – an effect similar to what happens to lettuce when it’s been in the crisper too long.

The steamiest places on the planet are getting warmer. Conservative estimates suggest that tropical areas can expect temperature increases of 3 degrees Celsius by the end of this century. Does global warming spell doom for rainforests? Maybe not. Carlos Jaramillo, staff scientist at the Smithsonian Tropical Research Institute, and colleagues report in the journal Science that nearly 60 million years ago rainforests prospered at temperatures that were 3-5 degrees higher and at atmospheric carbon dioxide levels 2.5 times today’s levels.

The rocks of Colombia’s Sierra Nevada de Santa Marta—the highest coastal mountain on Earth—tell a fascinating tale: The mountain collides and then separates from former super-continents. Volcanoes are born and die. The mountain travels from Peru to northern Colombia and finally rotates in a clockwise direction to open up an entirely new geological basin. Smithsonian scientists were part of a four-year project to study Santa Marta’s geological evolution. Their findings are published in the October 2010 special issue of the Journal of South American Earth Sciences.
