Journal Journal: College Textbook Affordability Act 11

I ran across an item in the local paper today that I think will interest young slashdotters who haven't yet finished with college. My US Senator, Dick Durbin, has authored the "College Textbook Affordability Act".

The paper says major provisions of the act were "included in the higher education reauthorization signed into law on Aug. 14."

Submission + - Group plans to bring Martian sample to earth

sm62704 (mcgrew) writes: "New Scientist has a story about IMARS (the International Mars Architecture for Return Samples) planning to bring samples of Martian siol to earth.

The robotic mission would be a needed precursor to manned trips to the red planet. Also, international cooperation is necessary since the US has already nixed bankrolling manned Mars missions."

Submission + - Brains hard wired for math

mcgrew (sm62704) writes: "New Scientist is reporting that "non-human primates really can understand the meaning of numerals."

The small study of two rhesus monkeys reveals that cells in their brains respond selectively to specific number values — regardless of whether the amount is represented by dots on a screen or an Arabic numeral.

For example, a given brain cell in the monkey will respond to the number three, but not the number one. The results suggest that individual cells in human brains might also have a fine-tuned preference for specific numerical values.
The report itself is online at PLoS Biology, Semantic Associations between Signs and Numerical Categories in the Prefrontal Cortex."
