Duplicating our organic tissue synthetically isn't as easy as it sounds.   Our bodily tissue is both soft and tough but modern implants - and replacement organs - will need to be as close to natural as possible to be effective.

A team of Australian and Korean researchers led by Geoffrey M. Spinks and Seon Jeong Kim has now developed a novel, highly porous, sponge-like material whose mechanical properties closely resemble those of biological soft tissues.  It consists of a robust network of DNA strands and carbon nanotubes. 

Dartmouth Medical School geneticists say they have made new inroads into understanding the regulatory circuitry of the biological clock that synchronizes the ebb and flow of daily activities, according to two studies published May 15. 

Research on the relationship between clocks and temperature, reported in Cell, offers insight into a longstanding puzzle of temperature compensation: why the 24-hour circadian rhythm does not change with temperature when metabolism is so affected.  A related study, in Molecular Cell, tracks a clock protein in action, mapping hundreds of highly choreographed modifications and interactions to provide the first complete view of regulation across a day. 

Let's be honest, the one thing you worry about most when driving your Hummer and sipping corporate-farmed coffee is how much damage that Union Oyster House ("oldest restaurant in America!") refrigerator magnet in your house is doing to the environment.   

You're out of luck.   The refrigerator magnets scientists are a step closer to making are for  environmentally-friendly 'magnetic' refrigerators and air conditioning systems.

The research group of Dr. Frédéric Charron, a researcher at the Institut de recherches cliniques de Montréal (IRCM), has made a discovery which could help treat spinal cord injuries and neurodegenerative diseases. This new finding has been published in the current issue of Neuron.

Astronauts John Grunsfeld and Drew Feustel successfully installed the Wide Field Camera 3 (WFC3) Thursday during the first of five scheduled EVAs, or spacewalks, to rejuvenate the Hubble Space Telescope.

Hubble was "full of surprises" for the astronauts, and EVA 1 took an hour longer than planned, but the veteran space and ground crews overcame all obstacles and Servicing Mission 4 (SM4) remains right on schedule.  (See the full scheduled timeline in my previous post.)

Have you ever thought about what's going on in your brain when you look at a painting that you like a lot?  While Neuroscientist Dr. Edward Vessel has and he's done brain imaging experiments to figure it out.

What happens in your brain when you have a pleasurable experience -- for example, when you see at a painting that you like very much.  Scientists describe this as an aesthetically pleasing experience.  They want to know if simply seeing a painting that you enjoy engages an emotional response and triggers the emotion circuits in your brain.

Did Language Invent Humans ?

Writing is a human invention.  We have plenty of evidence of its invention and of its improvement down the ages.  It would make no sense to assume that writing somehow 'just appeared'.  A magical origin of writing would presuppose that our brains are hard wired to read, but we all know that reading and writing are skills that must be taught in a formal manner.  Again, if we were 'hard wired' for written language then we would all use a single writing method, regardless of language.  Writing is most definitely invented.

Following on from the previous post, I wanted to pull out another couple of 'pointers to God' that Francis Collins and BioLogos like to present as part of their argument for belief. I like them because, far from being pointers to god, they are in fact powerful examples of the power of science and the weakness of religion as a tool to help us understand morality. They're great examples of how science is encroaching into what was once regarding as purely religious territory.

First example is this one - "Why is it wrong to torture an individual for the greater good?"

Although the theoretical applications for stem cell research are seemingly endless, the far-off possibilities are not as awe-inspiring as some scientists would like. Setbacks, ethical concerns and funding are all part of the hurdles that face all new scientific research, stem cell research especially. However, drastic results and benefits may be closer than previously thought.

    Last week I described how John Oro discovered that five hydrogen cyanide molecules (HCN) could react to produce adenine (H₅C₅N₅) one of the primary components of nucleic acids.
