This resulted in an underwater acceleration of 4 g, which was eight times better than that of previous robotic fish. But they’ve got a way to go yet to match the top recorded acceleration of real pike, 15 g. As New Scientist mused, “A robot with that kind of accel- t eration could be well suited to covert operations or navigating turbulent water.” Robofish is quick off the mark, New Scientist 208(2785): 21, 6 November 2010.

filaments with early life. “There is a willful blindness about these structures that sometimes has more to do with local politics than global truth,” he said. Kansas University researcher Craig Marshall drew a parallel between the Apex Chert saga and announcements about Martian life. “If we’re having problems here with ancient Earth sediments and there’s a huge debate, we want to try and be more stringent with our analytic techniques. We don’t want a repeat of the announcement in 1996 that, ‘Wow, we found life on Mars.’ I can’t recall the timeframe of how For the last 20 years it has been believed by some scientists that tiny branching structures in rocks of the (allegedly) 3.5-billion-year-old Apex Chert rock of Western Australia were fossilized bacteria. However, it has recently been shown thathese filament structures are hese filament structures are not remnants of life at all, but are simply tiny fractures in the rock filled with the minerals hematite and quartz. University of Oxford palaeobiologist Martin Brasier criticised previous researchers who “ignored the obvious” in their eager- ness to equate the branching It’s life … whoops, no it isn’t!

many days or weeks until they said, ‘Well, maybe we haven’t.’” However, note that although the latest study ruled out the filaments being fossilized life forms, it also found “an intriguing detail” in the surrounding rock, namely, carbonaceous material—which could be of biological origin. If it is, we can expect ongoing controversy about the Western Australian chert fossils, given the pressure such ‘ 3.5-billion-year-old biological evidence’ puts on evolutionary origin-of-life theories—see creation.com/ early-life-controversy .) Sadly, assuming there was sufficient carbonaceous material to do a carbon- 14
analysis, evolutionists would
not bother, as they presume
that the rock’s supposed age
rules out any carbon- 14 still
being present. But carbon- 14
could indeed be there (just
like in supposed billion
s-of-years old diamonds—see
because the rocks, in
common with rocks all over
the world, are actually only
thousands of years old.

evolutionists’ beliefs, there

More veggie dinos than ever Predators like T. rex and Velociraptor belong to the suborder Theropoda, which was long supposed to be largely, if not exclusively, carnivorous. A recent study by Lindsay Zanno and Peter Mackovicky of the Chicago Field Museum has overturned this notion. Examining 90 ‘species’ of theropods, using such methods as analyzing fossil- ized dung, they found that nearly half of them were vegetarian. This included ornithomimosaurs, therizinosaurs, oviraptorosaurs, alvarezauroids, and one of the troodontids. Dr Zanno says that theropods are mostly “clearly adapted to a predatory lifestyle”, so she assumes that the ones that ate plants started off as carnivores, then “went soft” in their later evolu- tion. However, another and perhaps more straightforward way of looking at this is that, clearly, large numbers of t f di osaurs that look designed ypes o nores are not that at all. to be carniv supportive of the Genesis This is very t originally, all creatures teaching thaome later must have turned ate plants.
