MPC1 is expressed in the human hair follicle, and inhibition of MPC inhibits cell cycle progression and disrupts gene expression of the hair follicle signaling pathway. A) MPC1 and PDK immunoreactivity in human hair follicle. CTS-connective tissue sheath. DP–dermal papilla; DSC–skin wrap cup; GL–germinating layer; HS–hair shaft; IRS-internal root sheath; L-ORS – lower outer root … Read more
Goldenrod plants can sense other nearby plants through reports of far-red light and adapt their responses when eaten by herbivores, suggesting a form of plant intelligence. Andre Kessler, a chemical ecologist, argues for plant intelligence by defining it as the ability to solve problems based on environmental information. His research shows that goldenrod releases chemicals … Read more
Chemical structure for thiamine pyrophosphate and protein structure of transketolase. Cofactor thiamine pyrophosphate in yellow and substrate xylulose 5-phosphate in black. Credit: Thomas Shafee/Wikipedia Scientists have prototyped a new method for “rational engineering of enzymes” to deliver improved performance. They have created an algorithm, which takes into account the evolutionary history of an enzyme, to … Read more
