Comment Fast and effective (Score 1) 113

I wrote some minor research programs in Pascal on a HP1000 minicomputer. They needed like 20 minutes to compile what I did in seconds with TP3. To that the error messages in the HP were cryptic. I ended up writing and test my programs in TP back home in the evening and type them into HP1000 the next morning. Much more effective.

Comment Of course there are differences (Score 1) 256

Mens brain are larger than womens and contains more neurons (Pakkenberg et al). If you correct for body weight, rats should be much smart than human. Brain size is not a good parameter. E.g. the bump whales brain is about 7kg, but the whale is probably not smarter than humans.
fMRI has a time resolution about 1s. An action potential in the brain can get from any point to any other in about 30ms, so fMRI makes images on an unphysiological time resolution.
There is no reason to try to blur differences. However, there should be more studies into factors influenicing brain size, e.g. genes, hormones, physical training and other activities. E.g. we know that size of the sensory area for the arm get smaller if you anesthezise the arm just for a few hour. The brain is very dynamic.

Submission + - Scientists Engineer One Protein To Fight Cancer and Regenerate Neurons (phys.org)

An anonymous reader writes: Our lungs, bones, blood vessels and other major organs are made up of cells, and one way our bodies keep us healthy is by using protein messengers known as ligands that bind to receptors on the surfaces of cells to regulate our biological processes. When those messages get garbled, it can make us ill with a host of different diseases. Now a team led by Stanford bioengineer and department chair Jennifer Cochran has tweaked one ligand in slightly different ways to produce two startlingly different results. One set of alterations caused neuronal cells to regenerate, while different tweaks to the same protein inhibited lung tumor growth. The experiments her team described in the Proceedings of the National Academy of Sciences were performed on rat and human cells or in mice that model actual diseases and are still far from being tested in humans. But the results show how scientists are becoming increasingly adept at tinkering with the body's protein-based control mechanisms to help vital organs heal themselves.

I don't know if I will believe in the aliens idea, but if it is it may be:
1. A spaceship with hairdressers and Telephone cleaners (Hitchhiker guide to the Galaxy)
2. Aliens looking for intelligent life somewhere and they just by change passed near us.
3. Aleins detected signals around this solar system and were exploring Venus or Jupiter
4. Aliens have found us, and have alreadyy sent down a landing capsule to Earth loaded with explorerer

Comment The local version (Score 1) 230

In 1981 I had the change to play with an HP system on its way out of production. To make a program you had to:
Load an editor from a punch (paper) band
Type in your programme
Save the source to punch tape
Load the compiler pass 1
Load the source
Run compiler
Save intermediate code to punch tape
Load compiler pass 2
Load intermediate code
Run compiler pass 2
Save compiled code to punch tape
Load linker
Load compiled code
Run linker
Save executable to tape
Load programme and test run

Comment The license (Score 1) 220

Is not a major part of the diffrence in success due to the license: In BSD you just take the code and use it, In most of the Linux-software it was GPL where you had to give back your development to the community?

Comment Neurons in human brain (Score 4, Insightful) 56

Nice work. I look forward to see the 1 millisecond time reolution. The researchers state that the human brain contain 85000*100000 -> 8.5 billion neurons. Most textbooks says the human brain has about 100 billion neurons. There are also papers out telling that the neocortex of a young male contain about 22.8 billion neurons (Pakkenberg). So the human brain is much more complex than stated.
