Deforestation can have a significant effect on tropical rainfall, new research confirms. The findings have potentially devastating impacts for people living in and near the Amazon and Congo forests. A team from the University of Leeds and the NERC Centre for Ecology & Hydrology found that for the majority of the Earth’s tropical land surface,…
Almost a decade after the U.S. human genome project was completed, scientists say they have mapped the underlying regulatory system that switches DNA on and off, potentially spurring a wave of new research into the molecular basis of complex diseases such as Type 1 diabetes. Many parts of DNA previously termed “junk” by scientists are,…
The U.S-based Wildlife Conservation Society says Asian governments must take action to protect Asian species that are at a conservation crossroads. The species include the tiger, orangutans, Mekong giant catfish, Asian rhinos, Asian giant river turtles and Asian vultures, a release from the society’s New York headquarters said. The WCS is urging governments to follow…
To see a hopeful future for science education, look no further than the Raccoon Creek watershed in rural Ohio. There, Vinton County High School students are literally getting their feet wet, testing water and examining fish to investigate the impact of acid drainage from more than a century’s worth of coal mining in the Appalachians….
Guys’ eyes are more sensitive to small details and moving objects, while women are more perceptive to color changes, according to a new vision study that suggests men and women actually do see things differently. “As with other senses, such as hearing and the olfactory system, there are marked sex differences in vision between men…
A new study by Stanford researchers has added fuel to a debate about the differences between organic and conventionally grown foods. The Stanford report, an analysis of 237 studies of organic produce, meats and dairy foods, concluded that organic foods are no more nutritious than their conventional counterparts. Advocates of organic foods, meanwhile, say that…
The malaria species rampant in the Asia-Pacific region has been a significant driver of evolution of the human genome, a new study has shown. An international team of researchers has shown that Plasmodium vivax malaria, the most prevalent malaria species in the Asia-Pacific, is a significant cause of genetic evolution that provides protection against malaria….
With the race to the White House heating up, it raises the question: where do the presidential candidates stand on global warming? In short, Obama is a global warming “believer” but has provided little substance to back his conviction and seldom talks about it. Romney, on the other hand, presents a wavering, sometimes mocking assessment…
Spinach power has just gotten a big boost. An interdisciplinary team of researchers at Vanderbilt University have developed a way to combine the photosynthetic protein that converts light into electrochemical energy in spinach with silicon, the material used in solar cells, in a fashion that produces substantially more electrical current than has been reported by…
Archaeologists have uncovered two 9,500-year-old cultic figurines in excavations just outside of Jerusalem, the Israeli Antiquities Authority (IAA) reported. Found at the Tel Moza archaeological site, one of the Neolithic figures is a limestone ram with precisely carved spiral horns. “The sculpting is extraordinary and precisely depicts details of the anima’s image,” the IAA excavators…
