Butterflies lose body fat during metamorphosis
A group of scientists from Oregon have discovered that butterflies experience a great loss in body fat during metamorphosis. view more (2006-03-21)
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)
Leptin found to control appetite and limb development in frogs
Leptin, the hormone secreted by fat cells that plays an important role in food intake, has been described for the first time in a cold-blooded vertebrate, the South African clawed frog Xenopus. view more (2006-06-13)
Hormone's role in insects could give insight for cancer treatment, malnutrition
Starvation typically has dire consequences for an organism's growth. In the tobacco hawkmoth, tissues starved during the last stage of larval development stop growing because they lack the proper nutrients. view more (2006-06-02)
Jekyll-Hyde neutron star discovered by researchers
Like something out of a Robert Louis Stevenson novel, researchers at NASA and McGill University discovered an otherwise normal pulsar which violently transformed itself temporarily into a magnetar, a stellar metamorphosis never observed before. view more (2008-02-22)
Cheering News for Depressed Mussels
One of Britain's rarest animals could soon be enjoying a revival in the country's waterways, thanks to researchers at the University of Cambridge. Depressed River Mussel populations have suffered a 30 per cent drop in the last 100 years through pollution and modern dredging techniques, and the... view more (2001-06-19)
Artist and scientists create a "walk-in brain"
Imagine what it would be like to walk into a brain and experience the sights and sounds of thinking in action. Norwegian artist Sol Sneltvedt set her own grey matter to work on this problem and, in collaboration with University of Sussex neuroscientist Professor Michael O'Shea, has created... view more (2004-03-24)
Parasites might spur evolution of strange amphibian breeding habits
Parasites can decimate amphibian populations, but one University of Georgia researcher believes they might also play a role in spurring the evolution of new and sometimes bizarre breeding strategies. view more (2007-11-15)
Professor analyzes nuclear receptors in bee genome
Susan Fahrbach, a Wake Forest University biologist, is among the more than 170 researchers who helped decode the honey bee genome. view more (2006-10-27)
New findings on immune system in amphibians
Krakow/Halle. Major Histocompatibility Complex (MHC) genes produce proteins that are crucial in fighting pathogen assault. Researchers from the Jagiellonian University in Krakow and from the Helmholtz Centre for Environmental Research (UFZ) characterized genetic variation and detected more than one... view more (2008-06-20)
New genetic analysis forces re-draw of insect family tree
The family tree covering almost half the animal species on the planet has been re-drawn following a genetic analysis which has revealed new relationships between four major groups of insects. view more (2006-10-27)
Cutting calories could limit muscle wasting in later years
Chemical concoctions can smooth over wrinkles and hide those pesky grays, but what about the signs of aging that aren't so easy to fix, such as losing muscle mass? Cutting calories early could help, say University of Florida researchers who studied the phenomenon in rats. view more (2008-09-17)
Latest papers from The Royal Society`s Journals
Please find below the summaries of papers in Proceedings A and B that are due to be published this week on FirstCite, the Royal Society`s new rapid online publication service. Passwords for this site can be supplied to bona fide media on request. PROCEEDINGS B (Biological sciences)... view more (2002-09-18)
Early exposure to common weed killer impairs amphibian development
Tadpoles develop deformed hearts and impaired kidneys and digestive systems when exposed to the widely used herbicide atrazine in their early stages of life, according to research by Tufts University biologists. view more (2008-04-16)
Giant Deep-Sea Tubeworm's Meal Ticket Comes in as a Skin Infection
Giant tubeworms found near hydrothermal vents more than a mile below the ocean surface do not bother to eat: lacking mouth and stomach, they stand rooted to one spot. view more (2006-05-22)
Spineless tales provide strong backbone to human brain research
University of Oregon biologist Nathan Tublitz talked about moths, flies and cephalopods, telling an audience of scientists meeting in Australia this week that research on these spineless creatures is unveiling the mechanics of how the brain regulates behavior. view more (2006-08-15)
Hubble sees 'Comet Galaxy' being ripped apart by galaxy cluster
There are many galaxies of different shapes and sizes around us today. Roughly half are gas-poor elliptical-shaped galaxies with little new star formation activity, and half are gas-rich spiral and irregular galaxies with high star formation activity. Observations have shown that gas-poor galaxies... view more (2007-03-05)
Elusive salamanders have role in developing new sampling models
Rare salamanders at a Georgia military base are the guinea pigs for Oak Ridge National Laboratory researchers whose goal is to develop methods to better determine whether a species has vanished. view more (2005-06-01)
Road losses add up, taxing amphibians and other animals
When frogs hit the road, many croak. Researchers found more than 65 animal species killed along a short stretch of roads in a Midwestern county. Nearly 95 percent of the total dead were frogs and other amphibians, suggesting that road-related death, or road-kill, possibly contributes to their... view more (2008-04-17)
