8th World Wilderness Congress announced

...obal terrestrial and marine wilderness inventories tell us how much wilderness is out there and where it is; up to 50 percent of the Earth's land is thought to still be "wilderness" The 1st Mega-Flyover Scientist/explorer Michael Fay, who gained international renown for his 1999 trek through Central Afr...

Why is Scotland's population shrinking and ageing? - A new research initiative

... historically low level. It is still too early to tell whether this recent increase will be sustained in the long-term. Fertility is lower in Scotland than in England, Wales and Northern Ireland. Fertility is also lower than in any of the English regions, including its near neighbour, the North East of...

Hawaiian soils reveal clues to cultural history

...s of soil and the history of agriculture in Hawaii tell the story of a human dependence on environmental processes. Chadwick's recent journal articles describe the work in detail. "Environment, Agriculture, and Settlement Patterns in a Marginal Polynesian Landscape," co-authored with soil scientists and ...

Scientists propose new method for studying ion channel kinetics

...O), and two closed (C) states, it is impossible to tell whether transitions connect the O to both C's (C-O-C), or to only one (C-C-O). We have found a set of simple models that can fit any data uniquely, so that data can always distinguish models in our set (it contains C-C-O but not C-O-C). This should a...

Study reveals new technique for fingerprinting environmental samples

The EGT fingerprints capture a DNA profile of a particular niche and reflect the presence and levels of nutrients, and pollutants, as well as f...

...ganisms in laboratory tests. "The bull's-eye could tell you: This is where the anthrax is," said Weiss. The researchers published their results in the April 28 issue of Nature. In addition to Weiss and Basu, authors of the paper are postdoctoral researcher Yoram Gerchman at Princeton and professor of chem...

A whole lot of shaking goin' on triggers early hatching in red-eyed tree frogs

...n examined the recordings to see whether she could tell how rain and snake-attack vibrations differed. "Two of the most obvious differences between vibrations caused by rain and vibrations caused by snakes are elements of the temporal pattern," she says. "Snake bites, in general, last longer than raindr...

African-Americans and Caucasians have similar emotional brain activity when seeing African-Americans

... said. "From looking at the amygdala, you couldn't tell if the scans were from African American or Caucasian participants. "Many people of either race may not be happy to find out that a part of their brain involved in responding to potential threats responds more to African Americans than Caucasians," Li...

Gold nanoparticles may simplify cancer detection

...cancerous cells and you look at the image, you can tell with a simple microscope that the whole cancer cell is shining," said El-Sayed. "The healthy cell doesn't bind to the nanoparticles specifically, so you don't see where the cells are. With this technique, if you see a well defined cell glowing, that'...

Little microbe inside sea squirt makes big splash

...f life inside its animal home, scientists couldn't tell if the bacterium or the sea squirt produced the sought-after patellamides, until now. By searching for patellamide synthesis instructions in genomic sequences, scientists found the bacterium indeed has the necessary genes to produce these potentially...

Ocean climate predicts elk population in Canadian Rockies

...limate statistics from the north Pacific Ocean and tell you how the elk are doing in Banff National Park. The University of Alberta doctoral student is the first researcher to show a correlation between the North Pacific Oscillation (NPO) and a mammal population. Based on many climate-related ocean measu...

Gene 'archeology' gets easier using Carnegie Mellon University software

Comparing genomes of different species can tell you when new genes evolved and what they do for their respective hosts. But pinpointing the ancestry of any given gene is a complex computational task. Now, powerful new software makes gene "archeology" considerably easier, reports a team of investig...

Epilepsy by the numbers

Even when awake, they cannot provide cluesthrough their speech, nor do abnormal movements necessarily indicate a seizure. One way for doctors to be certain whether a newborn is having aseizu...

The ultimate spa: embryonic body wash controls left-right development

..., in effect, set up a chemical gradient that would tell developing cells whether they were on the right or left side of the body. Using proteins labelled with fluorescent tags, the researchers demonstrated that the cilia pump was capable of transporting proteins of a similar size to known chemical messeng...

One gene links newborn neurons with those that die in diseases such as Alzheimer's

...ep was to label the two kinds of cells in order to tell them apart. The replaceable neurons send projections to another part of the brain a few millimeters away from the high vocal center to form part of the brain pathway that controls muscle movements related to singing. The neurons that are not replaced...

Love's all in the brain: fMRI study shows strong, lateralized reward, not sex, drive

BETHESDA, Md. (May 31, 2005) You just can't tell where you might find love these days. A team led by a neuroscientist, an anthropologist and a social psychologist found love-related neurophysiological systems inside a magnetic resonance imaging machine. They detected quantifiable love responses in ...

New technique helps identify multiple DNA regulatory sites

...derstanding the complex regulatory mechanisms that tell genes when to switch on and off is one of the toughest challenges facing researchers attempting to discover how life works. "Binding sites," or areas of DNA that interact with the proteins that help control gene expression, can be a long distance on ...
