NASA’s Hubble detects Exoplanet with glowing water atmosphere

NASA’s Hubble Space Telescope has discovered the strongest evidence to date for a stratosphere on a planet outside our solar system, WASP-121b. The stratosphere is a layer of atmosphere in which temperature increases with higher altitudes. The discovery was made by an International team of researchers led by the the University of Exeter by observing glowing water molecules in WASP-121b’s atmosphere.

IIT Delhi researchers develops new nanotechnology-based drug delivery system

An all-women team of researchers from Indian Institute of Technology (IIT) Delhi has developed a new drug delivery platform using nanoparticles. The nanotechnology-based drug delivery system has ability to boost the efficacy of antibiotics at the cellular level and improve chances of recovery from cancer-related bacterial infections. The nanoconjugate was able to kill 50% of bacteria at much lower concentration (400 nM) while the free peptide’s antibacterial activity was not significant at the same concentration.

IISc researchers develop low-cost, sensitive CO sensor

Indian Institute of Science (IISc) researchers from Bengaluru have developed a highly sensitive , low cost nanometre-scale carbon monoxide (CO) sensor, with potential applications in environmental pollution monitoring. The sensor was eveloped using novel fabrication technique that does not involve costly and time consuming lithography technology. Carbon Monoxide is a colorless, odorless gas. It is harmful when inhaled in large amounts. The greatest source of CO is internal combustions (IC) engines of cars, trucks and other vehicles or machinery that burn fossil fuels.
