Migratory moths may hitch their rides, but they're anything but drifters
Night-traveling migratory moths may hitch a ride on the wind, but a new study in the October 14th issue of Current Biology, a Cell Press publication, confirms that they are anything but drifters.   view more (2008-10-14)

Coating copies microscopic biological surfaces
Someday, your car might have the metallic finish of some insects or the deep black of a butterfly's wing, and the reflectors might be patterned on the nanostructure of a fly's eyes.   view more (2008-09-18)

Duck-billed dinosaurs outgrew predators to survive
With long limbs and a soft body, the duck-billed hadrosaur had few defenses against predators such as tyrannosaurs. But new research on the bones of this plant-eating dinosaur suggests that it had at least one advantage: It grew to adulthood much faster than its predators, giving it superiority in... view more (2008-08-06)

Passports for penguins
Ground-breaking technology that will enable biologists to identify and monitor large numbers of endangered animals, from butterflies to whales, without being captured, will be shown to the public for the first time at this year's Royal Society Summer Science exhibition [30 June to 3 July].   view more (2008-06-30)

Monarch butterflies help explain why parasites harm hosts
It's a paradox that has confounded evolutionary biologists since Charles Darwin published On the Origin of Species in 1859: Since parasites depend on their hosts for survival, why do they harm them?   view more (2008-05-15)

Researchers find natural section favors parasite fitness over host health
Why do parasites harm their hosts? Classic evolutionary theory predicts that parasites become more virulent because they must transmit themselves between hosts, yet scientists have found little data to support this idea, until now.   view more (2008-05-13)

Flowers' fragrance diminished by air pollution, University of Virginia study indicates
Air pollution from power plants and automobiles is destroying the fragrance of flowers and thereby inhibiting the ability of pollinating insects to follow scent trails to their source, a new University of Virginia study indicates.   view more (2008-04-11)

Smithsonian's National Museum of Natural History reveals ants as fungus farmers
It turns out ants, like humans, are true farmers. The difference is that ants are farming fungus.   view more (2008-03-25)

Can moths or butterflies remember what they learned as caterpillars?
Butterflies and moths are well known for their striking metamorphosis from crawling caterpillars to winged adults. In light of this radical change, not just in body form, but also in lifestyle, diet and dependence on particular sensory cues, it would seem unlikely that learned associations or... view more (2008-03-05)

Zoologists challenge longstanding theory that 'eyespots' mimic the eyes of predators' enemies
Circular markings on creatures such as butterflies are effective against predators because they are conspicuous features, not because they mimic the eyes of the predators' own enemies, according to research published today in the journal, Behavioral Ecology.   view more (2008-02-22)

Math Models Snowflakes
Three-dimensional snowflakes can now be grown in a computer using a program developed by mathematicians at UC Davis and the University of Wisconsin-Madison.   view more (2008-01-17)

Scientists unravel the molecular basis of monarch butterfly migration
Since its discovery, the annual migration of eastern North American monarch butterfly has captivated the human imagination and spirit. That millions of butterflies annually fly up to 2000 miles to reach a cluster of pine groves in central Mexico comprising just 70 square miles is for many an... view more (2008-01-09)

Smell-wars between butterflies and ants
Among humans, making yourself smell more alluring than you really are is a fairly harmless, socially accepted habit that maintains a complete perfume industry.   view more (2008-01-04)

New, rare and threatened species discovered in Ghana
Scientists exploring one of the largest remaining blocks of tropical forest in Western Africa discovered significant populations of new, rare and threatened species underscoring the area's high biological diversity and value.   view more (2007-12-07)

Primary rain forest is irreplaceable
As world leaders prepare to discuss conservation-friendly carbon credits in Bali and a regional initiative threatens a new wave of deforestation in the South American tropics, new research from the University of East Anglia and Brazil's Goeldi Museum highlights once again the irreplaceable... view more (2007-11-15)

New study uncovers secrets behind butterfly wing patterns
The genes that make a fruit fly's eyes red also produce red wing patterns in the Heliconius butterfly found in South and Central America, finds a new study by a UC Irvine entomologist.   view more (2007-10-26)

A gene divided reveals the details of natural selection
In a molecular tour de force, researchers at the University of Wisconsin-Madison have provided an exquisitely detailed picture of natural selection as it occurs at the genetic level.   view more (2007-10-11)

Study shows genetically engineered corn could affect aquatic ecosystems
A study by an Indiana University environmental science professor and several colleagues suggests a widely planted variety of genetically engineered corn has the potential to harm aquatic ecosystems. The study is being published online this week by the journal Proceedings of the National Academies... view more (2007-10-09)

New animal and plant species found in Vietnam
World Wildlife Fund scientists said today that the discovery of 11 new animal and plant species in a remote area in central Vietnam underscores the importance of conservation efforts in the ancient tropical forests of the region.   view more (2007-09-26)

UT researcher sheds new light on hybrid animals
What began more than 50 years ago as a way to improve fishing bait in California has led a University of Tennessee researcher to a significant finding about how animal species interact and that raises important questions about conservation.   view more (2007-09-18)

Climate change isolates Rocky Mountain butterflies
Expanding forests in the Canadian Rocky Mountains are slowly isolating groups of alpine butterflies from each other, which may lead to the extinction of the colourful insects in some areas, says a new study from the University of Alberta.   view more (2007-08-14)

Researchers witness natural selection at work in dramatic comeback of male butterflies
An international team of researchers has documented a remarkable example of natural selection in a tropical butterfly species that fought back - genetically speaking - against a highly invasive, male-killing bacteria.   view more (2007-07-13)

Arctic spring comes weeks earlier than a decade ago
In the Earth's cold and icy far north, the harsh winters are giving way to spring weeks earlier than they did just a decade ago, researchers have reported in the June 19th issue of Current Biology, published by Cell Press.   view more (2007-06-19)

WFU study finds that moths mimic sounds to survive
In a night sky filled with hungry bats, good-tasting moths increase their chances of survival by mimicking the sounds of their bad-tasting cousins, according to a new Wake Forest University study.   view more (2007-05-31)

Why are there so many more species of insects? Because insects have been here longer
J. B. S. Haldane once famously quipped that "God is inordinately fond of beetles." Results of a study by Mark A. McPeek of Dartmouth College and Jonathan M. Brown of Grinnell College suggest that this fondness was expressed not by making so many, but rather by allowing them to persist for... view more (2007-04-04)
