StealthyRoid writes: "A documentary set to air on BBC-4 on Thursday, March 8, makes the claim that the global warming alarmist camp has got the relationship between increasing C02 levels and global warming exactly backwards: That an increase in the Earth's temperature is the cause of elevated C02, and the slight uptick in global average temperature that we've been seeing is the result of cosmological effects, not human interference. The documentary also claims that the attempted "fixes" for global warming demanded by the alarmist movement (massive energy output reductions, de-industrialization, etc...) are going to end up hurting poor nations to the point where they're condemned to life in the stone age."

eldavojohn writes: "New Scientist is running a brief article on viruses playing a role in causing cancer. From the article, "During tumour development, the chromosomes of affected cells often become wildly rearranged, but no one knew why. Duelli and Lazebnik suspected that cell fusion — when two or more cells unite by merging membranes — might be to blame. Several common viruses can initiate this process.""

Submission + - New Radiation Treatment Drug Reduces Risk

eldavojohn writes: "A new drug developed is showing promising signs of reducing the risk of radiation death by almost 2/3. 5-androstenediol (AED), an adrenal gland hormone that stimulates marrow-cell growth will hopefully be something to use in emergency cases or in situations with a potential 'dirty bomb' to mitigate the amount of lives lost. From the article, "Amid growing fears of terrorist attacks with radioactive materials, the US government plans to award a contract for the treatment for acute radiation syndrome later this month under its revamped BioShield fund for civilian defences against chemical, biological and nuclear threats." An example of a capitalistic market at its finest or a result of over zealous terrorist fears?"

I went back to there cite last week and noticed they still have a newer version of the Brain Speed Test(although its seems to be in look only), but also a sister site about Brain Fitness. On this site they have new memory exercise called Word List Recall. Its pretty simple, but first couple times I found it tough to memorize...maybe Im just getting older. Enjoy. http://bfc.positscience.com/eval/wlr.php"

Submission + - Thorium the Key to Non-Prolfieration?

Submitted by P3NIS_CLEAVER on Wednesday February 28, 2007 @07:09PM

P3NIS_CLEAVER writes: Nuclear energy has been proposed as an alternative to coal power plants that generating carbon dioxide and emit mercury. As we are seeing now in Iran, the desire for nuclear energy has created a gray area that places peaceful civilian power generation at odds with nuclear non-proliferation. An article at Resource Investor claims that thorium reactors can be used to replace existing reactors without creating isotopes that may be used in nuclear weapons.

Submission + - Carbon transistor possible Silicon successor?

Submitted by dave_the_dodo on Wednesday February 28, 2007 @06:27PM

dave_the_dodo writes: New Scientist are reporting on a new carbon transistor[newscientisttech.com] 4 times smaller than the smallest silicon transistors. The transistors can be made from sheets of carbon just one-tenth of a nanometre thick. From the article:

The transistors are made of graphene, a sheet of carbon atoms in a flat honeycomb arrangement. Graphene makes graphite when stacked in layers, and carbon nanotubes when rolled into a tube. Graphene also conducts electricity faster than most materials since electrons can travel through in straight lines between atoms without being scattered. This could ultimately mean faster, more efficient electronic components that also require less power.
