Caribbean Leatherback Sea Turtles Stage Comeback May 8, 2006
The first week in May marked the emergence of the first hatchlings from leatherback turtles nesting on Sandy Point, St. Croix, U.S. Virgin Islands. If this year follows recent trends, it will continue one of the most positive turns for these endangered turtles, according to Earthwatch-supported findings recently published in the journal Biological Conservation.
‘Smart’ Genetic Therapy Helps The Body To Heal Itself
New approaches to genetic disease, based on cells’ own ability to correct themselves, were outlined recently at the annual conference of the European Society of Human Genetics in Amsterdam, The Netherlands. Instead of replacing a faulty gene (commonly referred to as gene therapy) these new ’smart’ approaches make use of the therapeutic potential that already exists in human biology.
Tibet Provides Passage For Chemicals To Reach The Stratosphere
NASA and university researchers have found that thunderstorms over Tibet provide a main pathway for water vapor and chemicals to travel from the lower atmosphere, where human activity directly affects atmospheric composition, into the stratosphere, where the protective ozone layer resides.
Statins May Improve Circulation In The Retina
The cholesterol-lowering medications known as statins may improve circulation in the eye, potentially reducing the risk of certain eye diseases, according to a study in the May issue of Archives of Ophthalmology, one of the JAMA/Archives journals.
Scientists Study Soot In Megacity Pollution
A team of Los Alamos scientists recently returned from a month-long data-gathering trip to Mexico City as part of an international, multi-agency environmental science collaboration. The March campaign was designed to examine the chemical and physical transformations of gases and aerosols in the polluted outflow from the Mexico City metropolitan area.
Weizmann Scientists Identify Basic Principles Of Communication
How do we succeed in putting our ideas into words, so that another person can understand them? This complex undertaking involves translating an idea into a one-dimensional sequence, a string of words to be read or spoken one after the other. Of course the person on the receiving end might not get the intended point: The effective expression of one’s ideas is considered an art, or at least a desirable and important skill.
In Undersea Habitat, Aquanauts Learn About Teamwork And Task Performance For The Moon And Mars
In isolated environments, astronauts, flight crews, offshore workers and military forces must maintain vigilance and work together to ensure a safe and successful mission. Participants in the NASA NEEMO 9 undersea project helped NSBRI (National Space Biomedical Research Institute) researchers study performance ability, problem-solving and team cohesion issues that could affect long-duration space flights.
New Understanding Of Parasite Cell Structures May Provide Treatments For Serious Tropical Diseases
For the first time, cellular biologists at the University of Georgia have developed new tools to study and localize glycosylphosphatidylinositol in living organisms and are discovering a new understanding of how they work in tropical parasites that cause human disease and suffering.
Researchers Create Non-invasive Imaging Method With Advantages Over Conventional MRI
New York University’s Alexej Jerschow, an assistant professor of chemistry, and Norbert Müller, a professor of chemistry at the University of Linz in Austria, have developed a completely non-invasive imaging method. Their work offers the benefits of magnetic resonance imaging (MRI) while eliminating patients’ exposure to irradiation and setting the stage for the creation of light, mobile MRI technology.
Researchers Map Links Between Size Of Hippocampus And Progression To Alzheimer’s Dementia
Researchers used novel 3-D mapping techiques sought to verify the theory that the hippocampus — the area of the brain that processes memory — is smaller in patients with mild cognitive impairment who develop into Alzheimer’s dementia, and that it is larger in patients with mild cognitive impairment who experience cognitive stability or improvement.
