Colour effects inspired by instant soup
The shimmering colors of beetle and butterfly wings are not usually due to pigments. Instead, these and rainbow effects are produced by interference - as in opal gemstones, or an oil slick on a wet road. Layers of colorless substances, of a thickness that lies within the wavelength of visible... view more (2002-09-20)
Where Have All the Butterflies Gone?
Cold, wet conditions early in the year mean that 2006 is shaping up as the worst year for California's butterflies in almost four decades. view more (2006-05-09)
Emerging model organisms featured in CSH Protocols
Biological research has long relied on a small number of model organisms, species chosen because they are amenable to laboratory research and suitable for the study of a range of biological problems. view more (2008-10-02)
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)
Modified home video game shows promise for stroke rehabilitation
Engineers at Rutgers, The State University of New Jersey, have modified a popular home video game system to assist stroke patients with hand exercises, producing a technology costing less than $600 that may one day rival systems 10 times as expensive. view more (2006-08-29)
UK Astronomers Survey Galactic Graveyard
An unprecedented source of planetary nebulae, the disk-like relics of elderly, dying stars, has been discovered in the southern part of our Milky Way galaxy. With about 1000 planetary nebulae found so far and many more still to be discovered, the number of aged stars in their death throes revealed... view more (2002-04-07)
Dutch ecologists plea for scientific research to aid risk assessment
A survey among nine prominent Dutch ecologists has identified gaps in knowledge on the potential effects of Bt-crops on food chains and ecosystems. Bt-crops have been modified to express a bacterial gene that codes for a toxin that kills certain groups of insects. The toxin is continuously produced... view more (2003-08-28)
Quantum chaos unveiled?
A University of Utah study is shedding light on an important, unsolved physics problem: the relationship between chaos theory - which is based on 300-year-old Newtonian physics - and the modern theory of quantum mechanics. view more (2008-08-07)
Nanofabrication method paves way for new optical devices
An innovative and inexpensive way of making nanomaterials on a large scale has resulted in novel forms of advanced materials that pave the way for exceptional and unexpected optical properties. view more (2007-10-08)
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)
Plants Control The Molting Of Insects
A special place on the market of food supplements belongs to ecdysteroid-containing preparations that are helpful as a tonic for sportsmen during intensive training sessions, for people of various professions connected with physical and psychological stresses, and also for elderly people.... view more (2002-11-10)
Bright white beetle dazzles scientists
An obscure species of beetle could teach us how to produce brilliant white ultra-thin materials, according to a research team led by the University of Exeter. view more (2007-01-19)
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)
Laurel Wilt of Redbay and Sassafras: Will Avocados be Next?
Scientists with the USDA Forest Service Southern Research Station (SRS), Iowa State University, and the Florida Division of Forestry have provided the first description of a fungus responsible for the wilt of redbay trees along the coasts of South Carolina, Georgia, and Florida. view more (2008-04-03)
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)
Butterfly fish 'may face extinction'
A beautiful black, white and yellow butterflyfish, much admired by eco-tourists, divers and aquarium keepers alike, may be at risk of extinction, scientists have warned. view more (2008-02-25)
Tropical insects 'go the distance' to inform rainforest conservation
The long-held belief that plant-eating insects in tropical forests are picky eaters that stay "close to home" - dining only on locale-specific vegetation - is being challenged by new research findings that suggest these insects feast on a broader menu of foliage and can be consistently... view more (2007-08-10)
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)
NYU physicists find way to create three-dimensional quasicrystals
New York University physicists have applied a ground-breaking nanotechnology method to create three-dimensional quasicrystals, highly ordered structures that, unlike conventional crystals, never repeat themselves. view more (2005-07-12)
EU-project strengthens monitoring the impact of climate change on nature
On March 1 the European Phenology Network (EPN) - a network to increase the use of phenological data and to stimulate monitoring and research in Europe in the context of climate change - will officially be launched during the first project meeting at Wageningen University, the Netherlands. The... view more (2001-02-27)
Nature press release for 17 January issue
[415331] LIFELINES: AIDS VACCINE PROGRESS (pp331-335; 335-339; N&V) An experimental AIDS vaccine is able to control infection in monkeys, researchers report in this week`s Nature. However, surviving virus may escape its effects by mutating, warns a second report in the same issue. AIDS is... view more (2002-01-17)
At Least Part of Climate Change is Man-Made
Humanity does seem to have been a major contributor to global warming after all. This has been demonstrated by new simulations carried out at the University of Bonn. The Bonn meteorologists used about 30 different models to investigate how the Earth's average annual temperature would have developed... view more (2005-04-13)
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)
Polymer opal films shed new kind of light on nature
Imagine cleaning out your refrigerator and being able to tell at a glance whether perishable food items have spoiled, because the packaging has changed its color, or being able to tell if your dollar bill is counterfeit simply by stretching it to see if it changes hue. view more (2007-07-24)
