Long ago genetic engineering got deep reach into pharmacological and food industry, agriculture and medicine. The trees are no exclusion, but genetic engineers started to deal with them approximately ten years later than with other objects: the trees are too difficult for genetic investigations and manipulations. The wood plant genetic engineering activities are now in full swing in different countries of the world, including Russia. When improving trees through classical selection methods, the resea

People facing economic hard times are more likely to vote when they believe government is at fault

Contrary to previous research indicating that people who are enduring financial hardship are less likely to vote, a study at Rice University suggests this is not always the case.
“Data from the American National Election Studies demonstrate that those facing economic adversity are more likely to vote when they blame the government for economic outcomes,” said Kevin Arceneaux, a poli

Biodegradable scaffold significantly increases the rate of bone healing

University of Toronto scientists have developed a biodegradable scaffold, similar in structure to a dish sponge, that significantly speeds the rate of bone healing.

The material, developed by an interdisciplinary team with expertise in engineering, biology, chemistry and dentistry, provides a building scaffold for bone growth. The scaffold, which eventually dissolves, increases healing rates and offers

Many creatures including our fellow primates the New World Monkeys rely on highly specific scent molecules called pheromones to find a suitable mate. Even our humble mammal cousin, the mouse, was found to have 140 genes just for pheromone receptors when its genome was completely sequenced earlier this year.

But humans are clueless when it comes to pheromone signals, according to University of Michigan evolutionary biologist Jianzhi “George” Zhang. He believes color vision put our pheromones

In a high-performance machine, each part is essential to the overall function of the whole. In ecology, species diversity is necessary to the smooth operation of the ecosystem. Until recently, little attention has been paid to the potential ecological effects on plant diversity from combined global environmental changes including increased atmospheric CO2, warming, elevated nitrogen pollution, and increased precipitation. Scientists from the Carnegie Institution’s Department of Global Ecology in

Doubling the amount of carbon dioxide in the air significantly reduces the number of plant species that grow in the wild, according to a newly released study on climate change in California.

The results, published in the Proceedings of the National Academy of Sciences (PNAS), are the latest findings from the Jasper Ridge Global Change Project at Stanford University – a multiyear experiment designed to demonstrate how grassland ecosystems will respond to predicted increases in temperature an
