Study shows lizard moms dress their children for success

...er said. "Orange-throated neighbors may indicate a trend in the frequency of orange-throated lizards within the population or in the overall population density." According to Sinervo, the density of the lizard population is probably a critical factor. At high densities, the aggressive orange-throated ma...

Hives ferment a yeasty brew, attract beetle pest

...ce and multiply. "If beekeepers can reverse the trend and eliminate the beetles, the hive can be saved," says Tumlinson. "If they can stop the beetles and remove eggs in the hive, the hive recovers." Honeybees are of major economic importance in agriculture as the major pollinating force for much orcha...

Allergy to hair dye increasing

Market research also indicates that more people are dyeing their hair and are doing so at a younger age. A survey in 1992 by the Japan Soap and Detergent Association found 13% of female high school studen...

Stability of mRNA/DNA and DNA/DNA duplexes modulates mRNA transcription

...ty and the mRNA level of genes. There is a general trend of increased mRNA level with increasing thermodynamic stability of the respective gene. Positive correlation was observed between the mRNA level and the stability of DNA/DNA and mRNA/DNA duplexes of both exons and introns. In contrast, an inverse rel...

Warming oceans threaten Antarctic glaciers

...aciers are changing too erratically to establish a trend with confidence. In contrast, four major glaciers in East and West Antarctica were shown to be retreating in unison, raising concerns that global sea level could rapidly rise if the oceans continue to warm. Dr. Andrew Shepherd, at the University o...

Global 'sunscreen' has likely thinned, report NASA scientists

...d around 1990. This switch from a "global dimming" trend to a "brightening" trend happened just as global aerosol levels started to decline, Mishchenko said. While the Science pap...

Antarctic warming to reduce animals at base of ecosystem, shift some penguin populations southward

...he world, especially in the Antarctic. A warming trend during the last few decades in the Antarctic Peninsula has already forced penguin populations to migrate south and perhaps diminished the abundance of krill that are at the base of the massive food chain at the bottom of the world. "We're already...

Are journal rankings distorting science?

...dual papers it publishes. But more worrying is the trend towards using impact factors to guide decisions on research funding. This has been particularly noticeable in the UK, where universities now prioritise scientific fields that produce research published in the highest impact factor journals, causing s...

Quitting smoking reduces risk of lung cancer mortality by 70 percent

...e smokers, a worrying finding given the increasing trend for women to take up the habit in many countries. The research paper's author, Dr Rachel Huxley, Director of Nutrition and Lifestyle at The George Institute for International Health (part of the APCSC Secretariat) said, "The importance of developi...

Satellites shed light on global warming

...here is now evidence there is a distinctive upward trend in global sea surface temperatures, and this we can now see from measurements made from Envisat," Professor Llewellyn-Jones said. Working like thermometers in the sky, a number of different satellite instruments measure SST on an ongoing basis, s...

The great escape -- fleeing fish fall in line

... Interestingly, results suggested that there is a trend for individual fish to maintain a given rank, indicating that the chronological order of escape responses within a school is maintained in successive startle events. Head of the research group Dr Paolo Domenici stated, “Our work is the first to s...

Chronic pain up almost 40 percent among US workers in past decade

In fact, the researchers predict that the world's oceans hold a few hundred thousand broadly distributed viral species, with some species-rich regions likely harboring the majority of thes...

Climate change creates dramatic decline in red-winged black bird population

...nd much of Northern Asia. It has been on an upward trend for the past 30 years. Weatherhead, an ecologist who specializes in the behavior of birds and snakes, says that although some people may be in denial, global warming exists. "There are long-term records that show melting glaciers and altered ecolo...

Fighting like a girl or boy determined by gene in fruit flies

...k. The fruit fly aggression model is part of a new trend to use fruit flies as models to study complex behaviors, including sleep and responses to painful stimuli, Tompkins said. "Drosophila have marvelous advantages in terms of genetic tricks," she said, "and flies in many respects behave and respond simi...

More kidney cancer is detected and treated early, yet death rate rises

... by greater use of surgery for kidney cancer, this trend has not led to fewer people dying. "With increased early detection and treatment of small tumors, we would expect to see a decrease in mortality associated with kidney cancer," says senior author Brent K. Hollenbeck, M.D., assistant professor of ur...

Too mellow for our predatory world

...x. 126,000 people descended on the island, and the trend is rising. And this causes problems. Not only do tourists disturb the many animals living on the Galápagos Islands; they also introduce alien animal and plant species which are causing great damage to local flora and fauna.
