Team discovers naturally occurring DNA-protein hybrids
Thanks to a serendipitous discovery and a lot of painstaking work, scientists can now build biohybrid molecules that combine the homing powers of DNA with the broad functional repertoire of proteins—without having to synthesize them one by one, res.....»»
Restoration in the temple of Edfu reveals new inscriptions, paint, and gold
Egyptian temples were not only colorful, but also gleamed in glistening gold. Columns, gates and obelisks have been covered in gold since the beginning of the Pharaonic Period. Researchers also know from textual sources that some of the buildings wer.....»»
Scientists discover how TGF-Beta sends its message even while tethered to the cell membrane
For years, scientists have thought that TGF-Beta, a signaling protein that holds sway over an astonishing array of cellular processes from embryonic development to cancer, could only do its work once it escaped a lasso-like "straitjacket.".....»»
Edible insects show promise as sustainable nutritional source
As the global population grows and traditional livestock production increasingly strains environmental resources, there is a rising interest in alternative protein sources. Edible insects, particularly grasshoppers, are abundant in regions like Camer.....»»
Apple is well on its way to making iPhones theft-proof
