Kangaroo mothers possess a superpower few animals share—they can pause their pregnancies. Through a process called embryonic diapause, a kangaroo can delay the development of a fertilized egg until conditions are just right.

If she already has a joey nursing in her pouch, the next embryo will remain in a suspended state, waiting its turn. Once the older joey becomes more independent, the embryo resumes growth and is born soon after. This reproductive strategy allows kangaroos to adapt to unpredictable environments, ensuring their young have the best chance of survival. It’s an extraordinary example of nature’s flexibility—and a reminder that in the animal kingdom, timing truly is everything.

Cows are ruminants, which means they have a unique digestive system designed to break down tough plant materials like grass. Unlike humans, cows have four compartments in their stomach, not four separate stomachs. These compartments work together to help digest food efficiently.

1. Rumen – The largest compartment. It stores food and begins the fermentation process with the help of microbes. This is where grass turns into usable nutrients.

2. Reticulum – Works closely with the rumen. It traps heavy or foreign objects (like nails – yes, cows sometimes eat accidentally!) and continues fermentation.

3. Omasum – This compartment absorbs water and nutrients from the digested food.

4. Abomasum – Known as the "true stomach." It functions similarly to our stomach, using acids and enzymes to digest proteins.

This fascinating system allows cows to extract energy from food that most animals can’t digest

*The giraffe weevil* (Trachelophorus giraffa) is a unique beetle species *native to Madagascar*. Its distinctive elongated neck, reminiscent of a giraffe's long neck, sets it apart from other insects.

*Physical Characteristics*

1. *Elongated neck*: Males have a notable extension of their head and thorax.

2. *Coloration*: Typically black and red.

*Habitat and Distribution*

1. *Madagascar*: Found in the island's forests.

*Behavior and Diet*

1. *Herbivorous*: Feeding on plants and leaves.

2. *Mating rituals*: Males engage in battles for mates, using their elongated necks.

*Conservation Status*

1. *Vulnerable*: Due to habitat loss and fragmentation.

*Interesting Facts*

1. *Sexual dimorphism*: Males have longer necks than females.

2. *Adaptation*: Elongated neck likely evolved for fighting and mating.

The giraffe weevil's unique appearance and behaviors make it an fascinating subject for study and observation.

Today is April 16. Let me introduce you to a woman whose work was central to the understanding of the molecular structures of , yet, her contributions to the discovery of the structure of DNA were largely during her life, for which she has been variously referred to as the "wronged heroine", the "dark lady of DNA", the "forgotten heroine", a "feminist icon", and the "Sylvia Plath of molecular biology". That great lady is our "scientist of the day" today.

It's death anniversary of , the dark lady of DNA - - -

(Scientist of the Day - 16 April)

Franklin graduated in 1941 with a degree in natural sciences from Newnham College, Cambridge. The research on helped Franklin earn a PhD from Cambridge in 1945. Moving to Paris in 1947 as a postdoctoral researcher, she became an accomplished and famous X-ray .

Franklin’s short scientific carrier produced brilliant contributions to the structure of carbon, DNA, and and spherical . At 30, she was a recognized authority who switched from carbon to DNA research and, a few years later, to nucleic-acid-protein complexes known as viruses. She made landmark contributions that led to two Nobel Prizes. She did not receive or witness either of them.

Her work on the X-ray diffraction images of DNA, led to the discovery of the DNA double helix for which , , and shared the 1962 Nobel Prize in Physiology or Medicine. Watson suggested that Franklin would have ideally been awarded the Nobel Prize in Chemistry along with Wilkins, but although there was not yet a rule against posthumous awards, the Nobel Committee generally did not give them.

More than 100 years after her birthday, Franklin’s scientific contributions are even more important now than during her lifetime. She received many (Posthumous) recognition/honors from all over the world:-

- In 1997, a newly discovered asteroid was named 9241 Rosfranklin.
- In 2004, Finch University of Health Sciences/The Chicago Medical School, USA changed its name to the Rosalind Franklin University of Medicine and Science.
- In 2019, the European Space Agency (ESA) named its ExoMars rover Rosalind Franklin.
- On 30 June 2021, a satellite named after her (ÑuSat 19 or "Rosalind", COSPAR 2021-059AC) was launched into space. etc.
