New chemical tool to block endocytosis in plants identified

Plant cells absorb many important substances through a process called endocytosis. In plants, endocytosis is essential for nutrient uptake, passing on cellular signals and plant-microbe interactions. However, the vital nature ...

New sensor detects rare metals used in smartphones

A more efficient and cost-effective way to detect lanthanides, the rare earth metals used in smartphones and other technologies, could be possible with a new protein-based sensor that changes its fluorescence when it binds ...

Shrinking a medical lab to fit on a fingertip

Identifying a patient's viral infection or diagnosing a blood disorder usually requires a lab and skilled technicians. But researchers at Princeton University have developed a new technology that goes a long way toward replacing ...

How nerve cells control misfolded proteins

Researchers have identified a protein complex that marks misfolded proteins, stops them from interacting with other proteins in the cell, and directs them toward disposal. In collaboration with the neurology department at ...

Toxin-spewing bacteria decoded

Scientists at Emory University School of Medicine have identified a central regulator of toxin production in the bacterium C. difficile, the most common cause of healthcare-associated infections in the United States. C. difficile ...

Study shows first evidence bacterial-induced apoptosis in algae

A new study by UAlberta biologists shows the first evidence of apoptosis, or programmed cell death in algae. The outcomes have broad-reaching implications, from the development of targeted antibiotics to the production of ...
