*Want to live longer? Eat mustard.(good news for mustard girl here) Canadian
researcher Steve W. Cui wants people to use more mustard. It's not just the taste that's great about mustard, says Mr. Cui, a research scientist with Agriculture and Agri-Food Canada in Guelph. It's also good for your health. (National Ottawa Citizen Online Dec 7, 99) http://www.ottawacitizen.com/national/991207/3256577.html

*Listening Hard for Microprobes Time Running Out. Two tiny probes that rode
aboard Mars Polar Lander but separated before entry appear to be lost forever as efforts to contact the larger spacecraft also continued without success. (ABC) This site has a interactive picture that opens a pop up box, this has a drop down box that carries you thru several options, one is a clickable picture of the mars polar lander, with descriptions of various instrumentations, pic of the target site, a video, and mars stuff. http://www.abcnews.go.com/ABC2000/abc2000science/marspolar_probes991206.html

*Screen science. Researchers performing multiple database manipulations
replace 'wet' experiences in the drug discovery process. *snip*As pharmaceutical researchers probe the genetic building blocks of life to attack more complex illnesses, this expensive ''wet'' science, as it is known, is no longer where drug discoveries are made. (The Boston Globe Dec 7, 99)-give it a minute to load.

*Expect Rapid, Pervasive Innovation In 21st Century. Innovative technologies
emerging over the next decade promise to affect virtually all aspects of everyday society, from transportation to health care, communication to recreation. (Science Daily's predictions Dec 6, 99) http://www.sciencedaily.com/releases/1999/12/991206071130.htm

*Iceland's Gene Pool Making Waves. Within weeks, an Icelandic company plans
to begin collecting DNA samples from Iceland's 270,000 citizens and linking the genetic profiles with their health records and family trees. The database it plans to build would offer an unprecedented chance to discover genetic links to disease - and an unprecedented danger to privacy, doctors and researchers attending a packed meeting of the American Society of Hematology said Sunday.

*Data derived from a balloon-borne probe of the early Universe provides
strong evidence that the Universe is flat and not open. The data is also consistent with the idea that a force, very possibly the theorized cosmological constant, a form of countergravitational "dark energy" thought to fill the universe, is helping drive the never-ending expansion of the Universe. (Dec 7, 99)

*New Ways To Expand The Mind: Re-creating The Power Of The Human Brain,
Using Machines The Size Of Blood Cells. What may be in store when it comes to boosting your brain power in the next century? CBS News Correspondent Richard Schlesinger reports that you may be able to get a memory upgrade for your brain. (CBS Dec 7,99)

*Rollersnake. Realistic robots are wriggling off the drawing board. Geeks
growing bored with Sony's robotic dogs could one day replace their motorised mutts with another high-tech toy: a robotic snake that moves just like the real thing. The technology could also be used to create robots capable of handling the toughest terrain--perhaps even on other planets. (New Scientist)

*Gene therapy yields super pigs. But will they fly with the public? Here
come the super pigs. Medical researchers using gene therapy have figured out a way to make young hogs grow 40 percent larger and faster. Scientists say the technique, which stimulates production of the pigs’ growth hormones, would be a boon for livestock farmers — and eventually could even be used to treat children with growth problems and to prevent muscle deterioration in AIDS and cancer patients.

*Quantum gravity presents the ultimate challenge to theorists. Physics in
the 20th century is founded on the twin pillars of quantum mechanics and the theory of relativity. However, in spite of the enormous successes of each theory individually, the two appear to be incompatible. This embarrassing contradiction at the very heart of theoretical physics remains one of the great outstanding challenges in science.

*An Invisible Dimension. Science fiction characters make travel through
extra dimensions look as easy as getting on the subway, but physicists have never taken them seriously. Now in the 6 December PRL a team proposes a radical idea: We may indeed live in a world with more than three spatially infinite dimensions, yet the extra dimensions might be essentially imperceptible. (Physical Review Focus Dec 2,99) http://focus.aps.org/v4/st28.html

*Toshiba discovers how to make voids in silicon. Toshiba has discovered how
to make what it calls "empty space in silicon" or ESS. The ability to form bubbles, pipes and flat plates as voids in silicon could be a useful addition to the range of techniques available for manipulating silicon and could be used to create novel silicon-on-insulator structures. (EE Times 12/7/99)

*Structure of Molecular Scissors Critical for the Shaping of Cells Revealed
by Structural Biologists at The Salk Institute. The living cell is the prototypical shape-shifter. At any given moment, it will reorganize itself to move, grow, replicate and even die.To achieve its Gumby-like existence, the cell's internal protein scaffolding, its cytoskeleton, is split apart and put back together ... over and over again. Until recently, little was known about how this basic life process was accomplished on the molecular level. But now scientists at The Salk Institute have shown in three-dimensional detail how remodeling begins in one of the most prevalent of these cytoskeletal proteins, called actin.

*Mouse stem cells can change their fate. Stem cells from the skeletal muscle
of adult mice have a "remarkable capacity" to transform themselves into blood cells, Texas researchers reported Sunday. The findings may one day lead to new ways to obtain cells for research, and perhaps to an alternative source for cells now available only from human bone marrow.

*A patent for DNA analysis owned by biotechnology giant Hoffman-La Roche was
obtained by deliberately misleading the U.S. Patent and Trademark Office and is invalid, a federal judge ruled Tuesday. U.S. District Judge Vaughn Walker upheld a challenge by Promega Corp., which argued that scientists got the patent in 1990 by misrepresenting their experiments and falsely claiming advances over previous discoveries.

*Cell Research: Welcome Controls. It's welcome news that the federal
government will soon begin sponsoring research on cells isolated from human embryos. That's because millions with serious diseases could benefit from medical discoveries that spring from the new research. (LA Times 12/7/99) Small article.

*So I'm happy to pass on the findings of a report on likely developments in
health care over the next decade, HealthCast 2010, prepared by PricewaterhouseCoopers (PwC), the chartered accountants and management consultants. It's an international study, based on interviews with 400 ''thought leaders'' and health care executives in many developed countries, including Australia. Most attempts to peer into the future of healthcare emphasise the effects of aging and the growing cost of medical technology. But this report highlights three other forces of change: more demanding consumers, the impact of the information revolution, and the way ''genomics'' will shift health care from cure to prevention.

*'Chaos' theory empowers researchers to predict epileptic seizures. Inspired
by an intriguing mathematical concept known as chaos theory, researchers at the University of Florida Brain Institute and the Malcom Randall Veterans Affairs Medical Center in Gainesville have developed a technique for predicting some types of epileptic seizures minutes to hours before they begin. (EurekAlert 12/8/99)

*Crystal fix. Biodegradable rods could help mend broken bonesLiquid crystals
are better known as the stuff of TV and laptop displays but surgeons could one day use them to rebuild shattered bones, say researchers in York. (New Scientist)

*Theory Of Memory: Grounded In Actions, Not Words. For those who get
flummoxed by how-to manuals, or stymied by instructions for assembly, University of Wisconsin-Madison psychologist Arthur Glenberg has a reassuring theory. It's not all your fault. The instructions run counter to how your memory works (UnicSci)

*Scientists Propose New Theories on Planet Formation New planetary systems
being discovered do not look much like our own because they may have been formed in a very different way, scientists said on Wednesday. (Yahoo 12/8/99)

*Methods Faulted In Gene Test Death Teen Too Ill for Therapy, Probe Finds.
Federal investigators have uncovered serious problems in the gene therapy experiment that killed a Tucson teenager in September, including new evidence that the young man should not have been allowed into the risky study because he was too sick at the time.
