Getting a moth antenna to seek anything but floral scents may be the challenge.
The fact that humans and other life forms “want” things may underlie the superiority of natural vision systems to machine vision systems. It will be interesting to see how easy the gap is to close — if it can be done at all.
Navigation expert Eric Cassell points out that algorithms have made the ant one of the most successful insects ever, both in numbers and complexity. Computer programmers use some of the same basic structures.
Researcher: “M. villosus swims at a speed of about 500 body lengths per second,” said Dr. Lavinia Gambelli, of Exeter’s Living Systems Institute (LSI)… “At first glance, this does not seem much. But in comparison, a cheetah achieves only 20 body lengths per second – so if an M. villosus cell had the size of a cheetah, it would swim at approximately 3,000 kilometers per hour.”
Researchers: Because of silk’s nanoscale size and the complex web architecture, little is known about the architecture and mechanics of three-dimensional (3D) spider webs during construction. This work comprehensively investigates the structure, mechanics, and functionality of a 3D spider web under construction, using consistent imaging and computational simulations methods.
Either jellyfish are smarter than we think or there is design in nature. Researchers: “The fact that these simple animals have figured out how to achieve a ‘ground effect’ type boost in open water, away from any solid surfaces, has the potential to open up a range of new possibilities for engineered vehicles to take advantage of this phenomenon,” Gemmell said.
Whoever wrote the media release was very, very light on the Darwinblather. Mind you, claiming that it all happened via endless iterations of natural selection acting on random mutations wears a bit thin when the time Darwinians thought they had has been sharply reduced.
The entire history of Kettlewell’s Peppered Moth experiment is littered with problems: doctored photographs, wrong assumptions and slim evidence, followed by genetic analysis revealing that the protein exons coding for color were not changed, but, rather, a transposon (non-random) was inserted in an intron (“junk DNA”). And now there’s this paper. It seems that the Read More…
So much complex, specified information and we are to believe it all just sort of happened via natural selection acting on random mutation (Darwinism)? Interestingly, this particular item doesn’t even make that claim. Maybe just too ridiculous.
Back in the 1960s, space scientists needed to know if it is true that a cat always lands on its feet: NASA contributed funding to the paper “A Dynamical Explanation of the Falling Cat Phenomenon,” published in the International Journal of Solids and Structures, by Stanford’s T.R. Kane and M.P. Scher. What was so significant Read More…
The mechanome is the underresearched “ the set of proteins or molecular entities that sense or respond to forces” within the cell (Allen Liu). Our earlier stab at the subject here at UD garnered 354 comments, so there’s no shortage of interest. The mechanome (and mechanobiology in general) plays a key role in research into artificial Read More…
Not just to zap prey, apparently. From Ed Yong at the Atlantic: It’s a remote control. It’s a tracking device. It can deliver shocks of up to 600 volts. But then you did want to stay awake, didn’t you? You think the electric eel is shocking? You haven’t seen anything yet. In this episode of Read More…
“three laureates discovered how to use molecules as components of tiny machines that can be controlled to perform specific tasks.”
Who knows, maybe we’ll end up farming termite colonies to work for us instead of just hiring pest control specialists to kill them.
First ever confirmed.
