Silk protein for scar-less healing

Silk protein for scar-less healing

Researchers have synthesized antibiotic-coated nanofibrous mats that can be used as material to dress and heal wounds caused by disease-related foot ulcers and various infections1. Chronic wounds like diabetic foot ulcers, venous ulcers and pressure sores affect millions globally. Such wounds are difficult to heal and sometimes necessitate amputations. To find an alternative dressing materialRead more about Silk protein for scar-less healing[…]

New maps show where to park spacecrafts on the Moon

New maps show where to park spacecrafts on the Moon

Detailed maps of lunar surface which will help identify sites where future missions can land have been created by astrophysicists who analyzed microwave emissions and surface temperatures1. Microwave remote sensing doesn’t require sunlight, making it suitable for monitoring surface features of remote targets such as planetary bodies. The researchers measured the microwave emissions of theRead more about New maps show where to park spacecrafts on the Moon[…]

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[…]
