...le," said Vors. The dramatic changes caused by global warming that happen in the Arctic and which impact on the herds include; earlier spring green ups that now occur before migrating herds arrive north and which deprive mothers and calves of quality feeding; warmer summers that cause more intense ins...

Analysis finds strong match between molecular, fossil data in evolutionary studies

...s. The work backs up a huge range of analyses among living and fossil animals, from trends in increasing body size in mammal lineages, to the dramatic ups and downs of diversity reported in the fossil record of evolutionary bursts and mass extinctions. "Our study also points the way toward new partner...

Scientists at CSHL discover mobile small RNAs that set up leaf patterning in plants

...on gradient that divides the developing leaf into a top and bottom half with different specialized cell types. A ta-siRNA 'gradient' determines the ups and downs of developing leaves The function of these ta-siRNAs is to specifically block the activity of a gene called ARF3. This gene defines the i...

In addition, longer-term ups and downs can be seen over periods of three to five years, with many cholera cases reported during some periods and few during others. Explanation...

Clones on task serve greater good, evolutionary study shows

...ions in the environment because in evolution, there are optimal traits to have, a place you want to be. Canalization prevents you from the minor screw ups along the way eating wrong, getting too much sun. It keeps you in the zone. The group studied different cloned offspring of the Arabadopsis, a plant...

Inevitably one of these two nascent protein plugs narrowly wins that race and reaches an energy state in which it can pull together all th...

People get better at managing life's ups and downs, and the result is that as they age, they become happier -- even though their objective circumstances, such as their health, decline." La...

Time of day tempers tadpoles' response to predators

...t there's a trade-off. The more a tadpole eats, the faster it grows big enough to transform into a frog; yet finding food requires being active, which ups the odds of becoming someone else's dinner. Scientists have known that prey adjust their activity levels in response to predation risk, but new re...
