Scientists discover dozens of new species in Lost World of western New Guinea
An expedition to one of Asia's most isolated jungles - in the mist-shrouded Foja Mountains of western New Guinea - discovered a virtual 'Lost World of new species, giant flowers, and rare wildlife that was unafraid of humans. view more (2006-02-07)
Notre Dame study provides insights into how climate change might impact species' geographic ranges
A new study by a team of researchers led by Jessica Hellmann, assistant professor of biological sciences at the University of Notre Dame, offers interesting insights into how species may, or may not, change their geographic range - the place where they live on earth - under climate change. view more (2009-06-24)
Cougar predation key to ecosystem health
The general disappearance of cougars from a portion of Zion National Park in the past 70 years has allowed deer populations to dramatically increase, leading to severe ecological damage, loss of cottonwood trees, eroding streambanks, and declining biodiversity. view more (2006-10-25)
Study explores plant phenotypic plasticity belowground
When we think of organisms actively searching for resources (foraging) we generally think of things like wolves stalking elk or butterflies finding flowers. Why don't we also think about plants growing roots through the soil? view more (2005-07-27)
New theory -- universal intelligence on animals and plants
Here it is proposed that life in all its variety is full of sensation and creates a complicated web of interaction with its surroundings. Mammals, birds and even fish mourn for a lost love. Single-celled organisms carry out tasks that are surprisingly complicated. We can demonstrate sensitivity in microscopic organisms, while plants emerge as... view more... (1999-03-25)
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)
AAAS plenary: Intrepid explorers and the search for the origin of species
Evolution, we know, is the guiding thread of biology and explains life as we know it. But how that big idea was inspired and expanded over two centuries of natural history is really a tale of the adventures of a handful of intrepid scientists whose derring-do, perseverance and intellectual curiosity sparked a revolution that forever changed our... view more...

Ume'å scientist presents discoveries about natural immunity in Science
A team including scientists at UCMP (Ume'å Center for Molecular Pathogenesis), a research unit at Ume'å University, shows in last week's issue of the journal Science that the protein PGRP-LC plays a crucial role in so-called innate immunity. Professor Dan Hultmark, post-doctoral fellow Svenja Stöven, and doctoral candidate Thomas... view more... (2002-03-04)
Butterfly proboscis to sip cells
A butterfly's proboscis looks like a straw -- long, slender, and used for sipping -- but it works more like a paper towel, according to Konstantin Kornev of Clemson University. He hopes to borrow the tricks of this piece of insect anatomy to make small probes that can sample the fluid inside of cells. view more (2009-11-23)
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)
New discovery: Molecular variation in one gene affects the growth of natural populations
For the first time, ecologists have been able to show that molecular variation in one gene may affect the growth of a population in its natural habitat. view more (2006-04-26)
Why Plants Talk To Insects - New Research from Imperial At Chelsea Flower Show (22-25 May)
Why talking to insects is so important to a plant's well-being is the theme of an unusual display at this year's Chelsea Flower show (22-25 May). The display, jointly staged by Imperial College at Wye and the ICI subsidiary, Quest International, will show how plants use scent and colour to attract helpful insects and to repel unwelcome herbivores.... view more...

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)
How does one sex grow larger than the other?
Why are males larger than females in some animal species (such as most mammals), females larger than males in others (such as most insects), and why are the sexes alike in yet other species (such as several birds)? view more (2007-01-30)
Insect population growth likely accelerated by warmer climate
Insects have proven to be highly adaptable organisms, able through evolution to cope with a variety of environmental changes, including relatively recent changes in the world's climate. But like something out of a scary Halloween tale, new University of Washington research suggests insects' ability to adapt to warmer temperatures carries an... view more... (2006-10-31)
Most widely used organic pesticide requires help to kill
The world's most widely used organic insecticide, a plucky bacterium known as Bacillus thuringiensis or Bt for short, requires the assistance of other microbes to perform its insect-slaying work, a new study has found. view more (2006-09-26)
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)
Spring into autumn to measure climate change
Volunteers have been so enthusiastic this year in recording the timing of natural events in springtime that an additional scheme is being run this autumn. Preliminary results from the huge volume of data gathered early in 1999 show that once again spring is arriving earlier in the UK. The dates when leaves first appear on the trees are ten days... view more... (1999-08-31)
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)
Green corridors lead nowhere
Green corridors, which have become a common feature of urban planning and conservation over the past decade, may make very little difference to the diversity of plants found in our towns and cities, ecologists have found. Speaking at the British Ecological Society’s Winter Meeting, to be held at the University of Warwick on 18–20... view more... (2001-12-10)
