'Acid rain' and forest mass: Another perspective

...d chemically, according to standard protocols. The location of parcels was carried out as a function of their distance from different foci of emission of contaminants. A flow equilibrium model for the canopy was drawn up together with a generalised micrometeorological model in order to estimate the total depo...

A new window into structural plasticity in the adult visual cortex

...cortical neurons, allowing Lee et al. to track the location and morphology of these neurons using two-photon microscopy. Time-lapse images of six pyramidal neurons and eight nonpyramidal neurons in 13 mice were taken over the course of four to ten weeks. The length of dendritic branch tips was measured over t...

U. of Colorado researcher identifies tracks of swimming dinosaur in Wyoming

...they were anchored, then somehow moving to another location and using the fingers to reattach. In the late 1980s the researchers observed that sea lilies could, in fact, move from place to place---Baumiller had put some in a flow tank and noticed that they changed position from day to day, and Messing had n...

Creeping crinoids! Sea lilies crawl to escape predators, new video shows

HIV inserts into human genome using a DNA-associated protein

...GF is the first such molecule found to control the location of HIV integration in human cells, according to a new study from researchers at the University of Pennsylvania School of Medicine. This study, published in this week's early online edition of Nature Medicine, describes the first clear target for mod...

How 'Dirt' Could Educate The Immune System And Help Treat Asthma

...linois at Urbana-Champaign indicates that the best location to store carbon dioxide in the deep ocean will change with climate change. The direct injection of carbon dioxide deep into the ocean has been suggested as one method to help control rising carbon dioxide levels in the atmosphere and mitigate the ef...

Climate change will affect carbon sequestration in oceans, model shows

The direct injection of carbon dioxide deep into the ocean has been suggested as one method to help control rising carbon dioxide levels in the atmosphere and mitigate the ef...

Researchers use brain scans to predict behavior

...s variably directed attention on each trial to the location of the stimulus prior to its presentation," says Maurizio Corbetta, M.D., the Norman J. Stupp Professor of Neurology and senior author of the study. Regardless of how the results are interpreted, Corbetta notes, the study clearly showed that visual p...

On a wing and a prayer - Alaska researchers seek clues to bird flu

...es. With gene sequences, bird species, geographic location and capture information in hand, Tom Marr, UA president's professor of bioinformatics, Jim Long, biotechnology computing technical leader, and Buck Sharpton, UA president's professor of remote sensing plan to create the first Web site of georeference...

MBL researchers probe how an ancient microbe thrives and evolves without sex

...otifers are in a different, perhaps less damaging, location than those found in other creatures. Many bdelloid DNA transposons have the same surrounding sequences, which may indicate preferences for specific locations. Indeed, many of them appear to be located at the tip of the chromosome in an area called th...

A step toward the $1,000 personal genome using readily available lab equipment

...sponding to the four DNA bases binds at a specific location on the genetic sequence, depending on which DNA base is present. The fragment then shines with one of the four colors, revealing the identity of the base. Recording the color data from multiple passes over the same sequences, a camera documents the r...

Drug resistant avian influenza viruses more common in Southeast Asia than North America

...ease outbreaks globally; and to serve as a central location for news, updates, and discussions of infectious disease outbreaks that threaten humans. For example, a ProMED transmission on July 6, 2005 noted that Joseph Domenech, the chief veterinary officer for the United Nations Food and Agriculture Organizat...

Metal-containing compounds show promise as HIV weapon

... also found to bind to the protease in a different location than the current class of protease inhibitors, so they may be effective against HIV strains that have become resistant to that class. Dr. Pavlina Rezacova, postdoctoral researcher in biochemistry at UT Southwestern, also participated in the study,...

Out of sight, out of mind? Not necessarily

...ing something but correctly identify the shape and location when forced to guess. Ro noted that his study demonstrates that TMS can be used successfully to induce blindsight in people with normal vision. Ro's co-authors on the PNAS paper were graduate student Jennifer Boyer and Stephanie Harrison, a summer ...

Elusive salamanders have role in developing new sampling models

...able to do a better job of predicting the type and location of suitable habitats plus minimize unnecessary and time-consuming sampling." Of more than 1,000 seasonal ponds at the 280,000-acre military facility in southeastern Georgia, 483 have been identified as potential candidates to support this particular...

'Cookbook recipes' would cure disease with nontoxic DNA delivery systems

...ers, for example, but delivering DNA to the proper location and getting the right amount of DNA expression without killing innocent cells has become the Achilles' heel in DNA delivery. Positively charged (cationic) synthetic molecules will readily bond to negatively charged DNA molecules and have been used f...

New technique could alter field of mouse genetics

...enetic beacon, so researchers can easily track its location without having to sequence the entire genome, as can happen with the chemical mutagen technique. In three months, the two graduate students who led the project, generated knockout mice for each of 75 different genes. Xu, Min Han, an HHMI investigato...

Computers close in on protein structure prediction

...to 100,000 different shapes based on the preferred location of the amino acids. Some amino acids tend to dive toward the watery world of the protein surface while others take cover inside the protein. The computer also accounts for the social habits of the 20 amino acids; some want to be close to each other a...

Carnegie Mellon cyLab researchers work to develop new red tide monitoring

The new software is designed to incorporate multiple computer vision algorithms and the domain knowledge from NOAA scientists. "Spatiotemporal data mining extracts changing spatial patterns from continuous data flow. It is a...

Stem cells bring fast direct improvement, without differentiation, in acute renal failure

... gene expression profiles. In fact, the intrarenal location of administered stem cells is such that it facilitates the delivery of renoprotective growth factors and cytokines to the sites where kidney cells are primarily destroyed from both the blood and urinary aspects of the cells that must be protected and...
