Anthrobots: Human Cell-Derived Tiny Robots Leave Scientists Surprised

Anthrobots:

  • These 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.
  • Size: They are measuring between the width of a human hair and the tip of a sharpened pencil.
  • Structure: 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.
  • Application
    • They hold promise for regenerative medicine, wound healing, and disease treatment.

Tracheal cells

  • These are from the lining of the bronchi/trachea, the network of tubes used to convey air to the lungs.
  • They are responsible for producing lubricating mucus to keep the airways functional and they are a type of epithelial cell, a term used generally to refer to cells lining the inside or outside of the body.
  • These cells generate mucus and a number of other compounds, which play an important role in respiration.

Vaishali and Praggnanandhaa, first brother-sister duo to become Grandmasters: What is the chess title?

Chess Grandmaster title:

  • Grandmaster is the highest title or ranking that a chess player can achieve.
  • The Grandmaster title and other chess titles is awarded by the International Chess Federation, FIDE (acronym for its French name Fédération Internationale des Échecs),
  • The title is the badge of the game’s super-elite, recognition of the greatest chess talent on the planet, which has been tested and proven against a peer group of other similarly talented players in the world’s toughest competitions.
  • Besides Grandmaster, the Qualification Commission of FIDE recognises and awards seven other titles: International Master (IM), FIDE Master (FM), Candidate Master (CM), Woman Grandmaster (WGM), Woman International Master (WIM), Woman FIDE Master (WFM), and Woman Candidate Master (WCM) are also be given.
  • All the titles, including that of Grandmaster, are valid for life, unless a player is stripped of the title for a proven offence such as cheating.
  • Revocation of title
    • The “use of a FIDE title or rating to subvert the ethical principles of the title or rating system may subject a person to revocation of his title”.
    • In case it is found after a title has been awarded that the player was in breach of the Anti-Cheating Regulations in one or more of the tournaments on which the title application was based, then the title may be removed by the Qualification Commission”.

Move over VoLTE, it’s Vo5G time: How it works and when’s India getting it

Voice over 5G:

  • It 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.
  • In simple terms, 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.

How is VoNR better than VoLTE?

  • VoNR brings clear advances over VoLTE with 5G’s substantially higher bandwidth and lower latencycompared to 4G LTE.
  • Enhanced call quality: It utilizes more advanced audio codecs that provide superior clarity and fidelity based on 5G’s increased data capacity.
  • Faster connection times: It promises faster call connection times, ensuring a seamless and prompt user experience.
  • Improved reliability: 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.

Human behaviour may be determined by fast changes in dopamine levels

Dopamine:

  • It is a neurotransmitter.
  • It is a chemical messenger that helps in the transmission of signals in the brainand 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 systemhas 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).
  • Where is dopamine produced?
    • 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 glandssmall 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 isphysically or mentally stressed. They cause biochemical changes thatactivate the so-called fight-or-flight response. That’s the body’s natural reaction to real or perceived stress.

Neurotransmitters

  • Neurotransmitters are chemical messengers that your body can’t function without.
  • Their job is to carry chemical signals(“messages”) from one neuron (nerve cell) to the next target cell.
  • The next target cell can be another nerve cell, a muscle cell, or a gland.

2000-year-old Copper Coins Discovered At Ancient Site Of Mohenjo Daro

Archaeologists in Pakistan have discovered a remarkably unusual cache of 2000-year-old coins within the remains of a Buddhist shrine, constructed at the historic site of Mohenjo Daro (Pakistan). The copper coins that were discovered are thought to date back to the Kushan Empire.

Mohenjo Daro:

  • Mohenjo Daro, or "Mound of the Dead" is an ancient Indus Valley Civilization citythat flourished between 2600 and 1900 BCE.
  • It lies in Pakistan''s Sindh province, on the bank of the Indus River.
  • It was discovered in 1922 by R. D. Banerji, an officer of the Archaeological Survey of India.
  • At about 3 mi (5 km) in circuit, it was the largest city of the Indus civilization, and it probably served as the capital of an extensive state.
  • It was built around the same time as the Great Pyramids of Egypt.
  • The ruins were designated a UNESCO World Heritage Site in 1980.
  • Laid out in a rectilinear grid and built out of baked bricks, the city f**eatured a complex water management system,**complete with a sophisticated drainage and covered sewer system, and baths in nearly every house.
  • The city included a 900-square-foot Great Bath and about 700 wells. The Great Bath is a rectangular public poolsituated in the citadel. These were part of a water system that enabled homes to have their own baths and toilets.
  • Mohenjo-Daro, like its contemporaries (Kalibangan and Harappa), was also divided into two parts: the citadel and the lower town.
  • Citadel:
    • The western mound, or Citadel was built on a raised platform of mud brick and consisted of all the important administrative structures like The Great Bathgranaries, and the College of Priests.
    • It was fortified by a thick mud-brick retaining wall.
  • Lower Town:
    • The eastern or low-lying part of the town was also fortified and was meant for the settlement of commoners.
    • Numerous streets and small alleys ran across this part of the city.
    • Within this section, many sub-partswere built according to the guild systems.
    • As people settled here, a large number of artifacts and information regarding the burial practices were found in this area.
    • Multi-storey buildings:
      • The people of Mohenjo-Daro lived in houses that had similar features throughout the town.
      • They consisted of a central courtyard surrounded by rooms.
      • Almost every household had individual toilets and bathrooms.
      • The doors and windows always opened in the alleys.
      • The concentration of wealth in the hands of a few can be seen through the dimensions of their houses. For instance, the commoners lived in single-storey houses while the rich lived in double or sometimes treble-storey houses.

Golden Mole Presumed Extinct Found Again in South Africa
