Study finds that active ionisation of air reduces noise
Updated : 2 years, 9 months ago IST
Did you know that by ionising the air with wires, you could make a loudspeaker? Simply put, creating an electric field strong enough to ionise the air molecules in a network of parallel wires or a plasma transducer can result in the production of sound. The charged ions are then driven along

Activity deep inside earth has an impact on global magnetic field
Updated : 2 years, 11 months ago IST
New research from geophysicists at the University of Leeds suggests that the way this super-hot core is cooled is key to understanding the causes of the peculiarities -- or anomalies, as scientists call them -- of the Earth's magnetic field.

Here's how magnetism affects animal behaviour
Updated : 3 years ago IST
Scientists summarize the methods used to explore how the Earth's magnetic field influences the behaviour of various animal species. This review is an ideal starting point for scientists wishing to enter this fascinating but poorly-understood topic in modern sensory biology.

Scientists explain the mechanism of cosmic magnetic fields explored in the
Updated : 3 years, 1 month ago IST
Recent research shows that magnetic fields can spontaneously emerge in plasma if the plasma has a temperature anisotropy. This mechanism is known as the Weibel instability. This new research is the first to unambiguously observe the Weibel instability in the laboratory. It offers a possible

Study models the transmission of foreshock waves towards Earth
Updated : 3 years, 2 months ago IST
An international team of scientists led by Lucile Turc, an Academy Research Fellow at the University of Helsinki and supported by the International Space Science Institute in Bern has studied the propagation of electromagnetic waves in near-Earth space for three years. The team has studied t

Next-generation material that adapts to its history: Research
Updated : 3 years, 3 months ago IST
Inspired by living systems, researchers have developed a new material that changes its electrical behaviour based on previous experience, effectively giving it a basic form of adaptive memory. Such adaptive materials could play a vital role in the next generation of medical and environmental

Scientists use deep planetary scans to confirm Martian core
Updated : 3 years, 4 months ago IST
Seismologists from The Australian National University (ANU) have developed a new method to scan the deep interior of planets in our solar system to confirm whether they have a core at the heart of their existence.

Astronomers uncover new 'patchy' proton aurora on Mars
Updated : 3 years, 6 months ago IST
Washington [US], September 5 (ANI): NASA's MAVEN and the United Arab Emirates' EMM missions have released joint observations of dynamic proton aurora events at Mars. By combining the observations, scientists determined that what they were seeing was essentially a map of where the solar wind

Neuroengineers use magnetic fields to activate neurons in fruit flies: Res
Updated : 3 years, 8 months ago IST
Washington [US], July 16 (ANI): Neuroengineers have created wireless technology to remotely activate brain circuits. Researchers showed they could control the behaviour of freely moving fruit flies using magnetic signals that activated genetically engineered neurons causing the flies to perf

Study: Astronomers find evidence for most powerful pulsar in distant galax
Updated : 3 years, 8 months ago IST
Washington [US], June 20 (ANI): Astronomers using data from the VLA Sky Survey have discovered one of the youngest known neutron stars possibly as young as only 14 years. The dense remnant of a supernova explosion was revealed when bright radio emission powered by the pulsar's powerful magne
