To supply amino acids for proteins inside the cells. Directed by Professors...
Medically accurate model of a tardigrade or water bear. The tardigrade, also called as the moss piglet or water bear is a strange, microscopic creature that appears like something out of a Disney nightmare scene: strange but not especially threatening. The pudgy, eight-legged, water-borne animal seems perpetually puckering. It's the farthest thing from what you...

A single free electron propagates above the special layered structure that the researchers engineered, only a few tens of nanometers above it.During its movement, the electron emits discrete packets of radiation called "photons". Between the electron and the photons it emitted, a connection of "quantum entanglement" is formed. Credit: Ella Maru Studio Researchers from the...
The world of science is everchanging and progressive. Every day a new scientific discovery is made. Here are some of the most relevant this year: Consumption of Microplastics Can Cause Evolutionary Changes After the non-biting midges of the species Chironomus riparius were exposed to microplastics, the genome of subsequent generations changed.

Credit: Joshi et al., Cell Reports, 2022 A new study by researchers in Spain reveals that human "look-alikes" who have comparable face features also tend to share many genetic resemblances, as well as also share certain lifestyle attributes. The research, released in the journal Cell Reports, gives some insight into the molecular genetic mechanisms that add...
Macro Woman Eye.
