Cassini Watches Explosion in Saturn’s E Ring
July 2, 2004
Something strange happened in the E ring of Saturn last January.  The incident is forcing scientists to conclude the ring cannot be very old.     The E ring is the broad, extended ring that extends from Mimas to Rhea (click here for diagram), over three times as broad as the main ring system but […]

Saturn Runs Rings Around Cassini
July 1, 2004
“Shocked” was how Carolyn Porco, lead Cassini imaging scientist, described her initial reaction to new pictures of Saturn’s rings.  Precious images began to pour in early July 1 from science observations right after the previous night’s perfect orbit insertion maneuver (see 06/30/2004 headline).  Even though the imaging team had been confident in the capabilities of […]

Cell Technology Celebrated
July 1, 2004
Humans are just beginning to imitate the manufacturing techniques cells use all the time, right under our noses.  A book just came out about the subject, entitled Bionanotechnology: Lessons from Nature by David S. Goodsell.  It’s hard to tell if Christof M. Niemeyer was more impressed with the book or with the living machines themselves, […]

Cassini to Rewrite Textbooks on Saturn
June 30, 2004
Hundreds of scientists and engineers are waiting with eager anticipation for SOI: Saturn Orbit Insertion, as the schoolbus-sized Cassini spacecraft races for its closest approach to the ringed planet tonight.  Just before closest approach, Cassini will fire its main engine for 96 minutes to slow down the spacecraft and allow Saturn to capture it in […]

Babies Walk in the Womb
June 29, 2004
New vivid ultrasound imaging technologies reveal a nursery of activity inside the womb, reports the BBC News.  Click the link to see the amazingly clear pictures.  Unborn babies have been observed stretching, kicking and leaping from 12 weeks, before the mother is aware, and “From 26 weeks, they appear to exhibit a whole range of […]

Key to Evolution of Culture Suggested
June 28, 2004
Visualize chimpanzees exercising their antics in the jungle: grooming, screeching at one another, chasing off rivals.  Now shift the scene to human activities in a large city: fans cheering their team at a stadium, an audience applauding a concert, kids screaming on an amusement park roller coaster, a congregation singing hymns at church, students taking […]

Milky Way Center Bathed in Unexplainably Hot X-Rays
June 25, 2004
The Chandra X-Ray Observatory found more heat at the center of the Milky Way than astronomers can explain.  Astronomers observed a tiny angle around the Milky Way’s center for 170 hours.  After subtracting out known sources, a diffuse gas cloud remains that is radiating X-rays at 100 million degrees.  Star counts capable of heating the […]

Biochemists Mutate Protein, Make a Catalyst
June 25, 2004
“Enzymes are among the most proficient catalysts known,” wrote three Duke University scientists, “and they catalyze a wide variety of reactions in aqueous solutions under ambient conditions with exquisite selectivity and stereospecificity.”  The team set out to rationally design their own enzyme.  Their work is reported in the June 25 issue of Science.1  Building on […]

Angry Evolutionist Seeks to Revive Peppered Moth Story
June 25, 2004
Michael Majerus has had it with creationists who leaped onto his 1998 book and used it for ammunition against Darwinism.  He had confessed that the simplified textbook story of the peppered moth was inaccurate, but he never meant to cast doubt on evolution.  Majerus (U. of Cambridge) is highlighted in a profile in the June […]

ID Book Survives Nature Relatively Unscathed
June 24, 2004
Considering the intemperate disdain intelligent design books usually receive from the major journals – when they are even noticed (see, for example, Nature’s review of a book by William Dembski in the 07/11/2002 headline) – a new ID book fared surprisingly well this week.  In Nature1 June 24, Douglas A. Vakoch (SETI Institute) reviewed the […]

Spiderman No Match for Real Spider
June 24, 2004
National Geographic News took the occasion of the upcoming Spiderman sequel to investigate the superpowers of real spiders.  If you were spidy, you could: Jump 50 times your body length.  That would be like a man jumping 300 feet (the world record is 29 feet, 4.5 inches). Walk upside down on smooth surfaces, with 170 […]

Cleaners Advertise in the Fish Market
June 22, 2004
The plot of this science project seems made for Disney animation, a fishy version of Aesop’s parable of Androcles and the lion.  There are fish that will clean parasites out of the mouths and gills of their predators without getting eaten (see 01/13/2003 headline).  How these “cleaner fish” and their clients developed this risky relationship, […]

Mystery of the Left-Handed Proteins: Solved?
June 21, 2004
Some molecules come in left- and right-handed forms that are mirror images of each other.  All biological proteins are composed of only left-handed amino acids.  How this could have come about in a primordial soup has long been a puzzle to origin-of-life researchers, since both L (levo, left-handed) and D (dextro, right-handed) forms react indiscriminately.  […]

Stickleback Fish Achieve Stardom in Evolutionary Labs
June 18, 2004
According to Elizabeth Pennisi in Science June 18,1 the three-spine stickleback is being studied in 100 labs as a model of evolution.  Over the last century, the little fish has been the subject of some 2000 papers, seven textbooks, and a Nobel prize-winning thesis.  Evolutionists have been attracted to this fish because it appears to […]
