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.

Researchers Found a New Species Fungi Named Troglomyces Twitteri

  • Researchers from the University of Copenhagen's Natural History Museum of Denmark discovered new species of parasitic fungus via Twitter.
  • The newly discovered fungus was named "Troglomyces twitteri", after Twitter.
  • The discovery was made by the biologist and associate professor Ana Sofia Reboleira of the National Natural History Museum.
  • She stumbled upon a photo of a North American millipede shared by US colleague Derek Hennen of Virginia Tech on Twitter in 2018.
  • The researcher spotted a few tiny dots on the North American millipede.

Exoplanet Climate 'Decoder' Aids Search For Life

  • After examining a dozen types of suns and a roster of planet surfaces, Cornell University astronomers have developed a practical model -- an environmental color "decoder" -- to tease out climate clues for potentially habitable exoplanets in galaxies far away.
  • Madden and Kaltenegger are co-authors of "How Surfaces Shape the Climate of Habitable Exoplanets," released May 18 in the Monthly Notices of the Royal Astronomical Society.

New Super-Earth with 617-Day Year Discovered

  • The discovery of a new, so-called "super-Earth" has just been announced by researchers, and it's about four times the mass of our home planet.
  • The discovery of the super-Earth was made thanks to an astronomical phenomenon known as gravitational microlensing.
  • And while the planet probably isn't habitable, that phenomenon is still an incredible manifestation of Einstein's general theory of relativity.
  • The discovery of the new super-Earth, dubbed OGLE-2018-BLG-0677, was outlined in a paper recently published in The Astronomical Journal.
  • The researchers involved with the study, including lead authors Dr. Antonio Herrera Martin and Associate Professor Michael Albrow, both at the University of Canterbury (UC) in New Zealand, made their discovery using a network of telescopes from across the globe.

ISRO to Tap Startups to Build Local Tech for Gaganyaan

  • India's space agency will tap startups to develop food and medicines for astronauts, better tools to access machines in a spacecraft and green engines for its maiden humanspace flight Gaganyaan-1.
  • It will also potentially help them build products and solutions that they can exploit commercially.
  • Isro identified a set of 17 technologies that it invited researchers to develop locally at lower costs for use in its Gaganyaan missions.

ARCI Scientists Develop Next-Generation Biodegradable Metal Implants

  • Scientists at the International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI) and Sree Chitra Tirunal Institute of Medical Sciences, Thiruvananthapuram both autonomous institutes under the Department of Science & Technology (DST) have jointly developed new generation Iron-Manganese based alloys for biodegradable metal implants for use in humans.
  • Biodegradable materials (Fe, Mg, Zn, and polymer), which can participate in the healing process and then degrade gradually by maintaining the mechanical integrity without leaving any implant residues in the human body are better alternatives to currently used metallic implants which remain permanently in the human body and can cause long-term side effects like systemic toxicity, chronic inflammation, and thrombosis.
