The world's favorite fruit only better-tasting and longer-lasting

Tomatoes, said to be the world's most popular fruit, can be made both better-tasting and longer-lasting thanks to UK research with purple GM varieties.

Video: Motion quotient - A brief visual task can predict IQ

A brief visual task can predict IQ, according to a new study. This surprisingly simple exercise measures the brain's unconscious ability to filter out visual movement. The study shows that individuals whose brains are better at automatically suppressing background motion perform better on standard measures of intelligence.

Researchers identify new target to boost plant resistance to insects and pathogens

Plants can't swat a bug or run away from one, but that doesn't mean that plants can't fight back. Plants have evolved unique and sophisticated immune systems to defend themselves against insects and pathogens. Plant hormones called jasmonates play an important role in this defense, but jasmonates have been found to also be important for plant growth. Now, researchers reporting in the May 23 issue

Thinking 'big' may not be best approach to saving large-river fish

Large-river specialist fishes — from giant species like paddlefish and blue catfish, to tiny crystal darters and silver chub — are in danger, but researchers say there is greater hope to save them if major tributaries identified in a University of Wisconsin-Madison study become a focus of conservation efforts.

Drought makes Borneo's trees flower at the same time

Tropical plants flower at supra-annual irregular intervals. In addition, mass flowering is typical for the tropical forests in Borneo and elsewhere, where hundreds of different plant timber species from the Dipterocarpaceae family flower synchronously. This phenomenon is all the more puzzling because both temperature and day length are relatively constant all year round due to geographical proximi

The tropical upper atmosphere 'fingerprint' of global warming

In the tropics at heights more than 10 miles above the surface, the prevailing winds alternate between strong easterlies and strong westerlies roughly every other year. This slow heartbeat in the tropical upper atmosphere, referred to as the quasibiennial oscillation (QBO), impacts the winds and chemical composition of the global atmosphere and even the climate at Earth's surface.

Scientists present new insights on climate change and species interactions

UCLA life scientists provide important new details on how climate change will affect interactions between species in research published online May 21 in the Journal of Animal Ecology. This knowledge, they say, is critical to making accurate predictions and informing policymakers of how species are likely to be impacted by rising temperatures.

Going green: Nation equipped to grow serious amounts of pond scum for fuel

A new analysis shows that the nation's land and water resources could likely support the growth of enough algae to produce up to 25 billion gallons of algae-based fuel a year in the United States, one-twelfth of the country's yearly needs.

Origins of human culture linked to rapid climate change

Rapid climate change during the Middle Stone Age, between 80,000 and 40,000 years ago, during the Middle Stone Age, sparked surges in cultural innovation in early modern human populations, according to new research.

'Whodunnit' of Irish potato famine solved

It is the first time scientists have decoded the genome of a plant pathogen and its plant host from dried herbarium samples. This opens up a new area of research to understand how pathogens evolve and how human activity impacts the spread of plant disease.

Amazon River exhales virtually all carbon taken up by rain forest

The Amazon rain forest, popularly known as the lungs of the planet, inhales carbon dioxide as it exudes oxygen. Plants use carbon dioxide from the air to grow parts that eventually fall to the ground to decompose or get washed away by the region's plentiful rainfall.

Climate change may have little impact on tropical lizards

A new Dartmouth College study finds human-caused climate change may have little impact on many species of tropical lizards, contradicting a host of recent studies that predict their widespread extinction in a rapidly warming planet.

Most scientists agree: Humans are causing climate change

Do most scientists agree that human activity is causing global climate change? Yes, they do, according to an extensive analysis of the abstracts or summaries of scientific papers published over the past 20 years, even though public perception tends to be that climate scientists disagree over the fundamental cause of climate change.
