Study explains spatial orientation differences between sexes

...how to determine their spatial orientation did not eliminate the differences between the sexes. "Since the instructions didn't remove the difference between how men and women judge spatial orientation, we believe it is likely a result of physiological differences," says Luc Tremblay, a professor in U of T's Fa...

Technology could enhance accuracy of breast biopsy

...ombines the two. While the fiber-optic probe won't eliminate the need for a biopsy, it will increase the likelihood that doctors will take a sample from the correct site. And because of improved optical technology, doctors may be able to make diagnoses right away, says Ramanujam. Additionally, the probe can b...

Mutant mice lead to memory insights

...nant-negative" form of the CBP gene -- which would eliminate normal gene function -- only in adult mice and only in the brain region known to be involved in memory formation. They could also switch this gene off, restoring normal CBP gene function. Importantly, the protein made by this dominant-negative CBP ge...

"But unless we are vigilant and collect plants locally and know when invaders appear, we cannot possibly defend against them." Plant collections play an active role in medical and public health and forensic science, Prat...

Are bacteria turning our own weapons against us?

...et," notes Budd. "Antibodies to the α2m could eliminate the microbe's α2m protection against the host allowing the bacteria to succumb to the host's immune defenses." Budd also noted that the gene didn't show a typical pattern for inheritance. In a normal case, he explained, if a gene is found in a...

Gene maps of simpler life forms point the way to human disease gene

From algae, weeds and people: new genetic clues to complex obesity syndrome

...ia, but the weed doesn't, so the researchers could eliminate genes and proteins that aren't involved in cilia, says Dutcher. The alga and humans shared 4,348 "fairly good" matches. Subtracting those also found in the weed cut the number of likely cilia-related proteins and genes to just 688. To see if these ...
