Since it launched on February 11, 2010, NASA’s Solar Dynamics Observatory, or SDO, has provided high-definition images of the Sun for over a decade. The images have provided a detailed look at various solar phenomena. SDO uses Atmospheric Imaging Assembly (AIA) to continuously look at the sun, taking images in 10 wavelengths every 10 seconds.…
If you think that your Broadband speed is fast enough, let us tell you about the fastest internet in the world to make you feel worse. In 2020, scientists at University College London had set a new world record for the fastest internet in the world at 178 terabits per second (Tbps). Now, scientists from…
A small ancient meteorite- almost 4.6 billion-year-old is likely the debris from the birth of the solar system. This 4.6 billion-year-old meteorite, found in the imprint of a horseshoe, trail carved in a field in Gloucester, could explain the origin of life on Earth. According to scientists, this small charcoal-colored space rock is a rare…
Metal oxides are an interesting class of materials intensively investigated nowadays. They have unique properties such as mechanical stress tolerance, high optical transparency, exceptional carrier mobilities, etc. The high optical transparency of metallic oxides allows it to be used in touch screens of smartphones and tablets, and solar cells. Scientists from the Institute of Materials…
Usually, scientists focus on blood tests for detecting different cancer types. These tests detect mutated DNA, shed by tumor cells when they die, known as cell-free DNA (cfDNA). It is quite difficult to detect tumor cfDNA in the blood because of the blood-brain barrier. The blood-brain barrier separates blood from the cerebrospinal fluid (CSF) surrounding…
High-density lipoprotein (HDL), produced by the liver and intestine, plays a significant role in cholesterol metabolism. It also has anti-inflammatory and antimicrobial properties. The liver synthesizes HDL levels in the body. However, the role of HDL produced by the intestine differs from the HDL produced by the liver, has not been identified. A new study…
According to scientists, solar activity results from instabilities in giant twists of magnetic ropes threading the Sun’s photosphere. Although, how these tangles form remains obscure, as there is no observational evidence. In new work, Dr. Christopher Prior of the Department of Mathematical Sciences, Durham University, and colleagues have developed a new approach to analyzing the…
Neurons communicate with each other via electrical signals and chemical neurotransmitters. At the junction between two neurons (synapse), an action potential causes neuron A to release a chemical neurotransmitter that passes the information to the next neuron. This type of neuron-to-neuron communication is known as evoked neurotransmission. Sometimes, neurotransmitter-packed droplets are released at the synapse…
Why is it that the colours of a t-shirt fade over time in the sun? Why do you get a sunburn, and why do the leaves of a tree turn brown in the autumn? These questions all have one theme in common, the interplay between dye pigments and ambient oxygen. Every child learns about this…
Mars has a dense core at its center made of iron, nickel, and sulfur. A rocky mantle surrounding the core and above that a crust made of iron, magnesium, aluminum, calcium, and potassium. The Mar’s crust composition records the planet’s integrated geologic history and provides clues to its differentiation. A planet’s crust bears witness to…
