Researchers have developed miniature robots using human cells and termed them as anthrobots.

  • Anthrobots are constructed from human tracheal cells which are bio-robots that possess self-assembly capabilities.
  • These are capable of both movement and healing neurons within a laboratory setting.
  • They can spontaneously fuse together to form a larger structure called a superbot, which was able to encourage the growth of neurons.
  • They are measuring between the width of a human hair and the tip of a sharpened pencil.
  • The anthrobots displayed diversity in structure and behavior. Some took on a spherical shape fully covered in cilia, while others resembled a football shape irregularly adorned with cilia.
  • These anthrobots are different from Xenobots, which are created from embryonic stem cells of frog.
  • They hold promise for regenerative medicine, wound healing, and disease treatment.

Voice Over 5G:

Reports indicate Reliance Jio, India’s largest mobile carrier, has been testing Voice over New Radio (VoNR) behind the scenes.

  • Voice over 5G is also known as Voice over New Radio (VoNR).
  • This standard allows voice calls over 5G networks instead of the current standard that uses 4G.
  • Vo5G takes all the improvements of 5G – speed, capacity, responsiveness – and applies them squarely to voice.
  • It aims to have all that infrastructure and interoperability ready well in advance.
  • To use Vo5G, you need three things: a phone that supports Vo5G, a carrier that offers Vo5G, and a 5G signal in your area.
  • VoNR brings clear advances over VoLTE with 5G’s substantially higher bandwidth and lower latency compared to 4G LTE.
  • It utilizes more advanced audio codecs that provide superior clarity and fidelity based on 5G’s increased data capacity.
  • It promises faster call connection times, ensuring a seamless and prompt user experience.
  • Vo5G aims to eliminate the notorious call drop issues, particularly during transitions between 5G and 4G.
  • Lower packet loss contributes to better reliability, minimising the occurrence of voice cutouts during calls.

Dopamine : New Study

A new study shows that dopamine release in the human brain plays a crucial role in encoding both reward and punishment prediction errors.

  • Dopamine is a neurotransmitter.
  • It is a chemical messenger that helps in the transmission of signals in the brain and other vital areas.
  • It is found in humans as well as animals, including both vertebrates and invertebrates.
  • It plays a role as a “reward center” and in many body functions, including memory, movement, motivation, mood, attention, and more.
  • Dopamine is released when your brain is expecting a reward. When you come to associate a certain activity with pleasure, mere anticipation may be enough to raise dopamine levels.
  • Dysfunction of the dopamine system has been implicated in different nervous system diseases.
  • High or low dopamine levels are associated with diseases including Parkinson’s disease, restless legs syndrome, and attention deficit hyperactivity disorder (ADHD).
  • Neurons in the region at the base of the brain produce dopamine in a two-step process.
  • First, the amino acid tyrosine is converted into another amino acid, called L-dopa.
  • Then L-dopa undergoes another change as enzymes turn it into dopamine.
  • In other parts of the body, dopamine acts as a type of hormone called catecholamine. Catecholamines are made in the adrenal glands- small hormone production factories that sit on top of the kidneys.
  • There are three main catecholamines: Dopamine, Epinephrine (adrenaline), and Norepinephrine.
  • These hormones get released into the bloodstream when the body is physically or mentally stressed.
  • They cause biochemical changes that activate the so-called fight-or-flight response.
  • That’s the body’s natural reaction to real or perceived stress.
