Data on stolen mobile can be destroyed remotely

Data on stolen mobile can be destroyed remotely

Scientists have developed a tiny embedded system that could remotely destroy the memory of stolen or hacked electronic devices such as mobile phones, laptops and pen drives to prevent data theft1. “This system could be integrated with state-of-the-art high-performance silicon chips, making it potentially useful for protecting data in various fields such as intelligence, nationalRead more about Data on stolen mobile can be destroyed remotely[…]

A chemical trick that makes metal atoms emit light

A chemical trick that makes metal atoms emit light

Nanoclusters of metal atoms are promising for their fluorescence, low toxicity and stability under light. However, the underlying causes of these features have not been adequately scrutinized, something that a new research from Saudi Arabia and China is trying to change by studying the metal atoms under different light and heat conditions to fine-tune theirRead more about A chemical trick that makes metal atoms emit light[…]

A simple technique to fiddle with silver atoms

A simple technique to fiddle with silver atoms

Organic ions or molecules that bind to the surface of noble metal nanoclusters are known as ligands. Usually, these ligands are modified to allow for tailoring the nanoclusters leading to potential practical applications. So far, however, it has not been well understood how modifying the ligand alters the electronic and optical properties of the metalRead more about A simple technique to fiddle with silver atoms[…]

A brain chemical can combat depression

A brain chemical can combat depression

Astrocytes transport nutrients such as lactate to neurons. Lactate activates certain genes linked to neurons’ plasticity, particularly at the nerve junction known as synapse, contributing to the formation of long-term memory. When astrocytes’ population dwindles, lactate levels in the brain fall, causing neurons to malfunction and leading to brain disorders such as depression. Now, aRead more about A brain chemical can combat depression[…]

Flexible sensors to track vital signs of the human body

Flexible sensors to track vital signs of the human body

Vertically stacked three-dimensional sensors exhibit low resistance, and consume less power and space1. The sensors are implantable and potentially useful for monitoring activities of brain cells, heart rates and body temperature. Current techniques stack sensors horizontally with a lot of wiring. Besides taking up space, they generate noise that attenuates desired signals. Researchers from KingRead more about Flexible sensors to track vital signs of the human body[…]
