Van Allen Probe A

March 13, 2026

Van Allen Probe A Latest News

NASA's 600 kg Van Allen Probe A satellite is falling back to Earth, raising questions about whether people on the ground should be concerned.

About Van Allen Probe A

NASA’s Van Allen Probes mission was the first mission to use two spacecraft in tandem to study Earth’s radiation belts.
Originally designed for a two-year mission, the Van Allen Probes A and B launched on Aug. 30, 2012, and gathered unprecedented data on Earth’s two permanent radiation belts — named for scientist James Van Allen — for almost seven years.
From 2012 to 2019, the spacecraft and its twin, Van Allen Probe B, flew through the Van Allen belts, rings of charged particles trapped by Earth’s magnetic field, to understand how particles were gained and lost.
The belts shield Earth from cosmic radiation, solar storms, and the constantly streaming solar wind that are harmful to humans and can damage technology, so understanding them is important.
By having two spacecraft with identical instruments, with one followed by the other along nearly the same path, researchers could measure changes that occur in Earth’s radiation belts over time and through space, providing insights into the physical dynamics of the radiation belts and changes that occur in this critical region of space.
NASA ended the mission after the two spacecraft ran out of fuel and were no longer able to orient themselves toward the Sun.

Chelonus (Carinichelonus) mahadeb Latest News

A rare parasitic wasp Chelonus (Carinichelonus) mahadeb named has been recently recorded from a tea estate in Assam.

About Chelonus (Carinichelonus) mahadeb

It is a new species of parasitic wasp.
It was discovered from Nahortoli Tea Estate in Assam.
Parasitic wasps of the genus Chelonus are tiny insects but play an important ecological role.
- They are known as egg–larval parasitoids, meaning they lay their eggs inside the eggs of other insects, usually moths and butterflies.
- The developing wasp larva eventually consumes the host, helping regulate insect populations naturally.
- Because many moth larvae are major agricultural pests, species of Chelonus are often considered beneficial insects that contribute to natural pest control in crop ecosystems, including plantations.
The discovery is notable because the subgenus Carinichelonus is extremely rare and poorly documented worldwide.
It is only the second new species of this subgenus described from India in recent times.

Peptides

March 13, 2026

Peptides Latest News

Globally, peptide therapeutics have been gaining attention in research as well as clinical practice.

About Peptides

Peptides are chains of amino acids that are naturally found in the body.
The amino acids in a peptide are connected to one another in a sequence by bonds called peptide bonds.
Peptides vs. Proteins:
Proteins and peptides are fundamental components of cells that carry out important biological functions.
Both proteins and peptides are made up of amino acids, but peptides contain far fewer amino acids than proteins.
Traditionally, peptides are defined as molecules that consist of between 2 and 50 amino acids.
Meanwhile, proteins are long molecules made up of multiple peptide subunits, and are also known as polypeptides.
In addition, peptides tend to be less well defined in structure than proteins, which can adopt complex conformations known as secondary, tertiary, and quaternary structures.
Proteins can be digested by enzymes (other proteins) into short peptide fragments.

Functions of Peptides

The body makes lots of different peptides, each of which has a different role.
They may provide pro-aging support, anti-inflammatory, or muscle-building properties.
Some peptides act as hormones, which are molecules that when released from cells, affect other areas of the body.
Due to the potential health benefits of peptides, many supplements are available that contain peptides that manufacturers have derived either from food or made synthetically.

What are Amino Acids?

Amino acids are molecules that combine to form proteins.
Amino acids and proteins are the building blocks of life.
There are 20 different amino acids.
A protein consists of one or more chains of amino acids (called polypeptides) whose sequence is encoded in a gene.
Some amino acids can be synthesized in the body, but others (essential amino acids) cannot and must be obtained from a person’s diet.
The nine essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
