School board adopts new science class text The Hillsboro Argus
An $80 textbook recommended by the Hillsboro School District for freshman science classes passed the approval of the school board this week, but not without opposition.
Molecular Solomon's Knot: Self-organization Leads To Intertwined Molecular Rings Science Daily
A team of researchers from the University of California, Los Angeles (USA), and Nottingham Trent University (UK) led by J. Fraser Stoddart have used a self-organization process to get molecular building blocks to weave themselves into a Solomon-type knot, and describe their results in the journal Angewandte Chemie.
Stem Cells Get A Grip Science Daily
At the American Society for Cell Biology's 2006 conference, scientists will describe how live cell imaging has revealed the very close relationship of hematopoietic stem cells and osteoblasts in the stem cell niche.
Researchers Create Genetically Matched Embryonic Stem Cells For Transplantation Science Daily
Researchers at Children's Hospital Boston report a new and efficient strategy, using eggs alone, for creating embryonic stem (ES) cells that can generate tissues suitable for plantation, because the cells are compatible with the recipient's immune system. The technique (done just in mice so far) would apply only to females, who would donate their own eggs to create genetically-matched ES
New System Solves The 'Who Is J. Smith' Puzzle Science Daily
Penn State researchers have developed an automated system that can determine which "J. Smith" is authoring papers on computer science -- the one who teaches at Penn State or the one who teaches at M.I.T -- as well as whether "J. Smith" is John Smith, Jane Smith, Joanna L. Smith or James H. Smith.
How Plastic Solar Cells Turn Sunlight Into Electricity Science Daily
A new analytical technique, featured on the cover of this week's issue of the Journal of Physical Chemistry B, could lead to the development of cheaper, more efficient solar cells. The information that this technique provides is a critical step in the development of a new class of solar cells, which promise significant savings in production costs compared to conventional silicon-based cells.
Embryonic Stem Cells Do Better On Bumpy Nanoscale Mattress Science Daily
At the American Society for Cell Biology's 2006 conference, scientists will report research showing that human embryonic stem cells do better when cultured on a substrate deliberately printed with nanoscale grooves and ridges.
Online Journal Combines Teaching Math And Studying How Students Learn Science Daily
When instructors at Bronx-area community colleges applied for a National Science Foundation (NSF) grant to study how students think about fundamental concepts of calculus, they hoped to gain a better understanding of how college students learn mathematics. During the 4-year project, the teacher-researchers integrated ongoing research theories with classroom teaching. As a result, their project
Inside IT: A cool new idea from British scientists: the magnetic fridge Guardian Unlimited
Solid-state fridge is greener and could halve your bills.
'The Secret of Scent' by Luca Turin Calendarlive.com
LUCA TURIN, the author of this engaging if odd book, has a rule when he is reading that he calls the "Paragraph Rule": In almost every science textbook there is one point, usually of paragraph length, where the style of the author matches exactly one's style of understanding and which we grasp properly and permanently.
