Science Updates Archive 9

For today's breaking news please see Today's Health and Bioscience News. For more Science Updates please see our Science Updates Archives
 

Life on Europa? - Stunning new photos transmitted by the Galileo spacecraft have revealed what may be a huge ocean of water, leading some scientists to predict that finding life there is all but inevitable. (4/9/97)

Obesity Virus? - Is obesity caused by a virus? New virological and biochemical findings could lead to new treatment approaches for obesity. (4/7/97)

Vanishing Coral - Coral reefs around the world are declining at a rapid rate, and scientists remain baffled as to the cause. (4/7/97)

Hepatitis A: Q & A - Quick reference information regarding the recent strawberry-linked hepatitis A outbreak. (4/7/97)

Artful Chromosomes - Artificial human chromosomes have been created for the first time. This feat will help scientists better understand what natural chromosomes do and how they do it, and could prove useful in gene therapy. (4/2/97)

Stardust Memories from Hale-Bopp - New studies of the fast-moving Hale-Bopp comet are providing valuable information on everything from how comets move, to the origins of the solar system and life on Earth. (3/27/97)

Extinction: Humans Speed the Pace - When humans move in, other species become extinct at a rate 100 times faster than when they are absent, according to recent studies conducted in the South Pacific Islands. (3/21/97)

Colon Cancer Pathway - The discovery of a genetic pathway linked to 90% of colon cancers should lead to enhanced treatments for the disease, report researchers at Johns Hopkins University.(3/21/97)

Mars Debate Continues - Sophisticated isotopic analyses appear to support the notion that the unusual Martian meteorite ALH 84001 does contain signs of life, according to new studies. (3/21/97)

Heading North - Each year, in late February, the snow geese begin their remarkable five-month return migration from their sunny winter homes in Mexico to their Arctic summer homes. Now, thanks to an innovative online research project, called Wild Wings, Heading North, you can track the daily progress of the birds as they make their way home. (3/20/97)

Motrin vs. Alzheimer's? - The over-the-counter pain relief medication ibuprofen (Motrin et al.) and related drugs appear to reduce the risk of developing Alzheimer's disease, according to a long-term study conducted by the National Institute on Aging. (3/10/97)

Chicken Brain Exchange - Making a chicken squawk and bob like a quail might seem like the ultimate stupid pet trick, but by accomplishing this task by cross-species brain cell transplantation, brain researchers truly have something to crow about. (3/9/97)

Making Citizen Scientists - As the new century approaches, mankind faces a number of difficult issues that depend on scientific expertise, such as the storage of nuclear wastes, or fossil fuels and global warming. The best hope for these kinds of problems is to empower people to become citizen-scientists. (2/18/97)

Ecosystem Meets Economics - The green science of ecology met the dark science of economics as leading thinkers met to discuss complex issues of human industry and planetary resources at a symposium on "Ecosystem Services" (2/18/97)

Promsing Breast Cancer Screen - A new breast cancer screening system utilizing low-level electrical currents could offer a safe and accurate alternative to current methods. (2/17/97)

Genetic Patent Decision - Leading geneticists expressed shock and dismay as word spread of the US Patent and Trademark Office announcement that it would allow patents on expressed sequence tags (ESTs), short sequences of human DNA that have proven useful in genome mapping. (2/17/97)>

Lively Mars Debate - Is, or was, there life on Mars? This basic question stirred lively debate at the AAAS meeting. (2/17/97)

Web Page for the Birds - A novel web project will literally be for the birds, and for any amateur bird watchers and scientists making ornithological observations across North America. (2/14/97)>

Model Of Cellular Furnace Created - Scientists for the first time have synthesized a working model of the enzyme cytochrome c oxidase, the "cellular furnace" providing the key heat and power in the chemistry of life. (2/14/97)

GLOBAL WEATHER: WINDS OF CHANGE - The Pacific Ocean appears to play a hitherto unexpected role in regulating the temperature and could be counteracting global warming. (2/14/97)
Eye Research Looks Good - Genetic discoveries, retina cell transplantation and bionic eye chips are three signs that the prospects for eye research are looking good. (2/6/97)

Key Immune Controller Gene - Researchers have identified and cloned a gene believed to play a key role in activating the immune system - and perhaps also in spurring on the human immunodeficiency virus that causes AIDS.(2/6/97)

Gene Therapy for Parkinson's - Researchers are optimistic that promsing results obtained in gene therapy experiments involving rats with Parkinson's disease could someday be applied to the treatment of humans. (2/6/97)

How Best to Save Endangered Species? - As intensive urbanization and agriculture put more species in line for the endangered list, better science is needed to determine which plants and animals are at greatest risk. (2/6/97)

Life from Venus - Although Mars has grabbed the headlines as a potential site of extraterrestrial life, Venus may have been the original source of life in our solar system. (2/6/97)

Groundhog Rhythm - Aside from predicting the coming Spring, the extraordinary sleeping and waking habits of the groundhog may help researchers better understand the effect of biorhythms on everything from fat metabolism, thyroid function, carcinogenesis and brain function. (1/31/97)

Dwindling Rhino Genes - Emergency conservation efforts may be the only thing that can save an endangered Asian rhinoceros with a distinctive genetic background. (1/23/97)

Nonviral Gene Therapy - A new non-viral gene therapy technique should help overcome some of the limitations of current approaches and opens new pathways to finding cancer therapies. (1/23/97)

Mars Travel Hazards - The discovery of what appear to be ancient bacterial fossils on a Martian meteorite may be leading NASA to reconsider the idea of a manned mission to the red planet. But such a trip won't be possible unless scientists first determine a way to protect the astronauts from the radiation hazards associated with such a trip (1/23/97)

Muscle and Memory - Muscle tissue is very particular in its choice of which nerve cells it will form a long-term relationship with, a new study shows.The finding could lead to a better understanding of how memories are preserved in the brain. (1/23/97)

New Oral HIV Test - A bloodless HIV-antibody test using cells from the patient's gums provides a highly accurate alternative to blood testing, according to a study published in JAMA. (1/15/97)

Toasting Reservatrol - Wine drinkers are toasting a new finding suggesting an anticancer effect for a compound found in wine and grapes. (1/15/97)
