While it's difficult to add muscles to a fossil when there is little or no evidence for muscles in the fossil record, and even tougher when the fossil has no living counterpart, Rieppel said their ideas are based on the preserved bone structures, biomechanics and the complexiti...

Binocular rivalry: Fulfilling visual expectations

...Ordinarily, our brain will fuse these two views to add depth to our visual world. However, if the two eyes' images are so different that they cannot be fused, we experience "binocular rivalry" a process in which one eye's image is perceived and the other's is suppressed. Every few seconds, perception sw...

In spite of the plant's long preparation for its flowery display, the blooms last, at best, two to three days, so visitors will have to be vigilant to see and smell ...

Two-pronged attack targeting EGF receptor hinders cancer cell growth

...e EGFR is a kinase, a cellular protein designed to add high-energy phosphate groups to proteins inside the cell, switching those substrate proteins on to conduct cellular signaling. Iressa and Erlotinib, on the other hand, hit the EGFR low, at sites inside the cell membrane where the kinase activity i...

Double-segment periodicity underlies 'odd' segment generation in centipedes
