Turning vegetable oil industry waste into power:...
In recent years, there has been growing interest in harnessing microorganisms for simultaneous wastewater treatment and renewable bioelectricity production. Microbial fuel cell (MFC) technology can convert the chemical energy stored in organic matter in wastewater into electricity, using bacteria as a catalyst. Researchers in Iran have been investigating how modification of the electrodes can improve the performance of this technology.

Researchers identify key gene controlling cadmium distribution...
Cadmium (Cd), a toxic heavy metal contaminant of cultivated land, is harmful to humans through its accumulation in crops, especially rice. Therefore, strategies to limit Cd accumulation in rice grains are urgently needed. In rice, Cd is taken up from the soil by the roots and then transported to tissues aboveground. The nodes, which are vascular bundles connected to the roots, leaves and panicles, play an important role in the redirection of Cd in rice.

3 Questions: Mriganka Sur on the research...
Rett syndrome is a devastating developmental disorder, principally occurring in girls, caused by mutations in the gene MECP2 that leads to severe cognitive, motor, and other symptoms. As such, the March 10 approval by the U.S. Food and Drug Administration of the first-ever treatment for the disorder, a drug called Trofinetide based on the natural protein IGF-1, brings new hope to patients and their families. The approval is also a dream come true for Mriganka Sur, Newton Professor of...

Triggering bitter taste receptors could someday treat...
Surprisingly, bitter taste receptors are not only located in the mouth, but also elsewhere in the body, including the airways. Activating those receptors opens up lung passageways, so they’re a potential target for treating asthma or chronic obstructive pulmonary disease (COPD). Now, researchers report that they have designed a potent and selective compound that could lead the way to such therapies.

New “traffic cop” algorithm helps a drone...
How fresh are your data? For drones searching a disaster zone or robots inspecting a building, working with the freshest data is key to locating a survivor or reporting a potential hazard. But when multiple robots simultaneously relay time-sensitive information over a wireless network, a traffic jam of data can ensue. Any information that gets through is too stale to consider as a useful, real-time report. Now, MIT engineers may have a solution. They’ve developed a method to tailor...
