March 30, 2026

Solar Radio Burst Latest News

Researchers from the Indian Institute of Astrophysics (IIA) have made a significant breakthrough in understanding a long-standing solar mystery regarding solar radio burst.

About Solar Radio Burst

It is defined as an intense solar radio emission associated with solar flares.
Origin: These are observed in radio wavelengths most frequently during solar transients, such as coronal mass ejections (CMEs) and flares.
SRBs are direct signatures of accelerated electrons in the solar atmosphere.
These are observed across a wide range of wavelengths, from millimetres to kilometres, corresponding to frequencies from the GHz to the kHz range.
- Observations at short wavelengths correspond to distances close to the solar surface, while those at long wavelengths correspond to the large distances from the Sun.
Types: Considering the morphological characteristics, five main categories of solar radio bursts can be distinguished: Type I, Type II, Type III, Type IV, and Type V.
Impacts
- These solar transients have a direct impact on the near-Earth atmosphere.
- It can interfere with Global Navigation Satellite System (GNSS) signals by reducing signal-to-noise ratio and causing loss of lock.

Extracellular RNA

March 30, 2026

Extracellular RNA Latest News

Recently, scientists reported that extracellular RNA (exRNA) from bacteria can persist in disinfected drinking water.

About Extracellular RNA

The exRNA is RNA that exists outside cells.
It is found in body fluids such as blood, saliva, urine, and cerebrospinal fluid.
To survive outside the cell, exRNA travels in its own molecular containers that prevent enzymes from breaking it down before it reaches its destination.
These are heterogeneous populations including small (e.g., miRNA) and long non-coding RNAs and coding RNAs (e.g., mRNA).
Functions: It has been found to be part of a sophisticated long-distance communication system, allowing cells to deliver instructions to other cells, influencing behavior and gene activation.
It helps coordinate responses in the immune system, tissue repair, and development.
Medical significance
- It enables diagnosis of diseases like cancer and heart disease through RNA pattern testing in body fluids
- It has potential for early detection and monitoring.
