A new study reveals how we could design robots to think like bees. Honey bees excel in weighing effort against reward and risk, quickly determining which flowers can provide sustenance for their colony. A study recently published in the journal eLife illustrates how eons of evolution have fine-tune

“We trained 20 bees to recognize five different colored ‘flower disks’. Blue flowers always had sugar syrup,” says Dr. MaBouDi. “Green flowers always had quinine [tonic water] with a bitter taste for bees. Other colors sometimes had glucose.” “If the bees were confident that a flower would have food, then they quickly decided to land on it taking an average of 0.6 seconds),” says Dr. MaBouDi. “If they were confident that a flower would not have food, they made a decision just as quickly.”
The team then built a computer model from first principles aiming to replicate the bees’ decision-making process. They found the structure of their computer model looked very similar to the physical layout of a bee brain.

Researchers discover key functions of plasma membrane–cell wall adhesion in rice and critical genes involvedIn a study published in Nature Plants, a research team led by Prof. Chao Daiyin from the Center of Excellence for Molecular Plant Sciences of the Chinese Academy of Sciences identified a novel protein family in plants named as GAPLESS, and revealed that members of this family mediate the adhesion between the cell wall and the plasma membrane at the Casparian strip (CS), a barrier in the root endodermis. This adhesion plays a critical role in controlling nutrient transport and the growth development of rice.
