Astronomers Create Cloud Atlas for Hot, Jupiter-Like Exoplanets

  • Giant planets in our solar system and circling other stars have exotic clouds unlike anything on Earth, and the gas giants orbiting close to their stars—so-called hot Jupiters—boast the most extreme.
  • A team of astronomers from the United States, Canada and the United Kingdom have now come up with a model that predicts which of the many types of proposed clouds, from sapphire to smoggy methane haze, to expect on hot Jupiters of different temperatures, up to thousands of degrees Kelvin.
  • Surprisingly, the most common type of cloud, expected over a large range of temperatures, should consist of liquid or solid droplets of silicon and oxygen, like melted quartz or molten sand.
  • On cooler hot Jupiters, below about 950 Kelvin (1,250 degrees Fahrenheit), skies are dominated by a hydrocarbon haze, essentially smog.

IASST Develops Electrochemical Sensing Platform

  • Institute of Advanced Study in Science and Technology (IASST), Guwahati, developed an electrochemical sensing platform.
  • It will detect carcinogenic or mutagenic compound N-nitrosodimethylamine (NDMA) and N-nitrosodiethanolamine (NDEA) that are found in food items like cured meat, bacon, some cheese, and low-fat milk.
  • It was achieved by developing a modified electrode by immobilizing carbon nanomaterials (carbon dots) in Deoxyribonucleic acid (DNA).
  • People are exposed to harmful chemicals belonging to Nitrosamine family in cured meats, bacon, some cheese, low-fat dry milk, and fish.

IIT-M Researchers Develop Low Cost Solar Parabolic Trough Collector

  • Researchers at the Indian Institute of Technology-Madras (IIT-M) have developed a low cost Solar 'Parabolic Trough Collector' (PTC) system for concentrating solar energy with industrial applications in areas such as desalination, space heating and space cooling, among others.
  • This indigenously designed and developed system was lightweight with high energy efficiency under Indian various climatic and load conditions.
  • The National Solar Mission was launched with the target of providing 20,000 MW through solar power by 2022.
  • However, lower rate of energy generation through solar power was a major roadblock in achieving this target.

Australia 'Records Fastest Internet Speed Ever'

  • Researchers in Australia claim they have recorded the fastest ever internet data speed.
  • A team from Monash, Swinburne and RMIT universities logged a data speed of 44.2 terabits per second (Tbps).
  • At that speed, users could download more than 1,000 high-definition movies in less than a second.
  • According to Ofcom, the average UK broadband speed currently is around 64 megabits per second (Mbps) - a fraction of that recorded in the recent study.
