Brain Circuit Linked To Pregnancy Food Cravings Identified
Pregnant women have experienced exotic food cravings since recorded history began. This may be why.
Rutgers Geneticists Propose Biotech Crop Containment Strategy
Plant geneticists at Rutgers may have solved one of the fundamental concerns about genetically engineered or modified (GM or GMO) crop agriculture: genes leaking into the environment.
In a recent paper published in the Proceedings of the National Academy of Science, Rutgers Professor Pal Maliga and research associate Zora Svab advocate an alternative and more secure means of introducing genetic material into a plant. In GM crops today, novel genes are inserted into a cell nucleus but can eventually wind up in pollen grains or seeds that make their way out into the environment.
Crater Galle: The 'Happy Face' On Mars
These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show the Galle Crater, an impact crater located on the eastern rim of the Argyre Planitia impact basin on Mars.
The HRSC obtained these images during orbits 445, 2383, 2438, 2460 and 2493 with a ground resolution ranging between 10-20 metres per pixel, depending on location within the image strip.
The images show Crater Galle lying to the east of the Argyre Planitia impact basin and south west of the Wirtz and Helmholtz craters, at 51° South and 329° East.
The images of the 230 km diameter impact crater are mosaics created from five individual HRSC nadir and colour strips, each tens of kilometres wide.
Impact Of Rainfall Reaches To Roots Of Mountains
The erosion caused by rainfall directly affects the movement of continental plates beneath mountain ranges, says a University of Toronto geophysicist — the first time science has raised the possibility that human-induced climate change could affect the deep workings of the planet.

Implicit Stereotypes And Gender Identification May Affect Female Math Performance
New research may provide insight as to why, despite progress over the last few decades, women remain underrepresented in math-heavy majors and professions.
In an article published in the January issue of Psychological Science, psychologists Amy Kiefer of the University of California, San Francisco and Denise Sekaquaptewa of the University of Michigan point to an interaction between women's own underlying "implicit" stereotypes and their gender identification as a source for their underperformance and lowered perseverance in mathematical fields.
