Radical Attack on Live Cells

Stimulation of tiny areas on cellular surfaces with free radicals using a microfluidic probe

08-Apr-2021 - Is there a way to chemically manipulate small, confined areas on cellular surfaces? Scientists have developed a microfluidic probe to send a flow of free radicals on live cells and track the outcome using fluorescence imaging. As outlined in the journal Angewandte Chemie, this approach makes it ...

Demystifying mechanotransduction ion channels

01-Mar-2016 - As blood flows through our vessels, the cells that constitute these vessels responds to the shear stress of blood flow to ensure normal circulation. This process of converting a mechanical force into a biological function is known as "mechanotransduction." But a bit of mystery has enshrouded the ...

Imitating synapses of the human brain could lead to smarter electronics

13-Nov-2015 - Making a computer that learns and remembers like a human brain is a daunting challenge. The complex organ has 86 billion neurons and trillions of connections - or synapses - that can grow stronger or weaker over time. But now scientists report the development of a first-of-its-kind synthetic ...

Flexible supercapacitor raises bar for volumetric energy density

Could be woven into clothes to power wearable medical, communications devices

13-May-2014 - Scientists have taken a large step toward making a fiber-like energy storage device that can be woven into clothing and power wearable medical monitors, communications equipment or other small electronics. The device is a supercapacitor—a cousin to the battery. This one packs an interconnected ...

Casting a wide net to fight coronaviruses

07-Sep-2005 - Coronaviruses - the family of viruses that causes the common cold - gained widespread recognition when the deadly severe acute respiratory syndrome, familiarly known as SARS, killed at least 800 people in 2003. Research efforts to design antiviral agents to combat coronaviruses intensified after ...
