[Niko McCarty. @NikoMcCarty]

Genome length strongly correlates with cell size; even more than cell complexity, number of protein-coding genes, etc. This was extremely surprising to me.

Initially, I expected that genome size would correlate with protein-coding genes. Although there is a linear relationship in prokaryotes (which have compact genomes with fewer regulatory elements), there is a logarithmic relationship in eukaryotes. A eukaryote called Edhazardia aedis, for example, has a genome with ~51 million nucleotides that only encodes 4,200 proteins. Some bacteria have genomes that are about an order-of-magnitude smaller in length, yet encode more proteins than this!

And what of cell complexity? Surprisingly, there is no relationship between genome length and complexity. Eukaryote genomes range in size by 200,000-fold. There are amoebas, salamanders, and small plants with genomes much larger than our own. An onion’s genome is five times larger than a human’s.

The closest correlation — and one that scales across kingdoms of life — is between genome length and cell size. Many papers on this subject have been written by T. Ryan Gregory, a Canadian biologist, who has collected thousands of examples of genome sizes and cell sizes. Gregory also maintains a database on genome sizes across the tree of life, at genomesize[dot]com.

In a 2007 paper, Gregory plotted this relationship for red blood cells taken from various organisms, such as fishes, amphibians, reptiles, and birds. (Red blood cells were selected so that each “type” of cell would be standardized across the organisms.) See chart #1 below.

Many recent papers continue to show the same relationship. I downloaded raw data from a 2023 paper, for example, that lists genome sizes and cell volumes for thousands of bacteria and eukaryotes. 53 organisms in this dataset have both a recorded cell volume *and* genome size, and those points are plotted in the second chart below.

The question is why this relationship exists at all. What does genome size have to do with cell size?

Many biologists argue for some kind of physical scaling. The size of a cell’s nucleus corresponds closely with its overall size, and most cells keep their “nuclear-to-cytoplasmic volume ratio” at a constant level. The more DNA a cell has, then, the more space it occupies, and the larger its nucleus (and overall cell size) must be to maintain this ratio.

This explanation is unsatisfying. For one, bacteria don’t have a nucleus, so why does this scaling apply to them? And second, the genome typically occupies less than 1% of the total nucleus volume, so why would a larger genome lead to a bigger nucleus mechanistically? There is plenty of space in there!

(Sidebar: A tiny fern from a South Pacific island has the world’s largest genome: 160.45 billion bases, more than 50-times larger than a human genome. If stretched out, this genome would be longer than the Statue of Liberty is tall; and yet, it occupies only a small portion of the fern’s nucleus.)

The reality seems to be that biologists don’t really understand (to a satisfying degree) why this relationship is true. Simple questions in biology often yield exceptionally complex answers.

#DRDO के वैज्ञानिकों द्वारा एक और उपलब्धि की गयी, जो हेडलाइन में छूट गई। अब भारत एक विशिष्ट समूह का हिस्सा है, भारत सातवां ऐसा देश है जो गैलियम नाइट्राइड चिप टेक्नोलॉजी को उपलब्ध कर पाया। यह तकनीक आधुनिक लड़ाकू विमानों, उन्नत राडार और इलेक्ट्रॉनिक युद्ध (Electronic Warfare) प्रणालियों की रीढ़ है।

AESA राडार: आधुनिक फाइटर जेट्स (जैसे राफेल, तेजस मार्क-2) में Active Electronically Scanned Array (AESA) राडार का उपयोग होता है। GaN चिप्स इन राडार की रेंज और टारगेट को ट्रैक करने की क्षमता को कई गुना बढ़ा देती हैं।

इलेक्ट्रॉनिक युद्ध प्रणाली: दुश्मन के राडार को जाम करना हो या उनके सिग्नल्स को ब्लॉक करना हो, GaN तकनीक से लैस सिस्टम बहुत ज्यादा घातक और सटीक साबित होते हैं।

चिप (Semiconductor) निर्माण की तकनीक दुनिया के गिने-चुने देशों के पास ही है, और युद्ध या तनाव की स्थिति में कोई भी देश अपनी सबसे एडवांस तकनीक दूसरे को नहीं देता।

Elite Club में एंट्री: भारत का इस विशिष्ट क्लब में 7वां देश बनना यह सुनिश्चित करता है कि अब हमें इन क्रिटिकल कंपोनेंट्स के लिए किसी दूसरे देश की शर्तों या प्रतिबंधों के आगे झुकना नहीं पड़ेगा।

लागत में कमी: स्वदेशी तकनीक होने के कारण रक्षा बजट का एक बड़ा हिस्सा देश के भीतर ही रहेगा और आयात पर निर्भरता खत्म होगी।

ये चिप्स प्रासंगिक हैं क्योंकि इन्हें आधुनिक लड़ाकू विमानों में उन्नत राडार और इलेक्ट्रॉनिक युद्ध प्रणाली में उपयोग किया जाता है। भारत की GaN #technology क्लब में प्रवेश आत्मनिर्भरता के बारे में है। यह #DRDO और वैज्ञानिक डॉ. मीना मिश्रा द्वारा संभव हुआ।

She says “this isn’t Shiva” with the same authoritative, yet false conceit with which she translated a Ramayana verse as Sita calling Rama a misogynist pig.

This is the game that “public facing” historians play to provoke us simpletons from high above the ivory tower—it keeps them relevant & sells books.

Don’t lodge expletives—educate yourself as to how academic credentialism & a peer review cartel are manipulated to claim authority, dismiss native voices & as my friend @indumathi37 has written, commit epistemic violence.

Prof. Chaturvedi spoke on the evolving role of universities in shaping a future-ready India through research, innovation, entrepreneurship, and academic excellence, while emphasising the importance of bridging the industry-academia gap and building globally competitive institutions rooted in Indian values. He also highlighted Nalanda University’s global character, Net Zero campus, manuscript digitisation initiatives, and the vision of reconnecting ancient wisdom with contemporary challenges through interdisciplinary learning and the Nalanda spirit.

The Chuknagar massacre is among the deadliest attacks on Hindus during the 1971 war, yet it remains largely unknown.

The Pakistan Army k!lled fleeing Hindus who had gathered in Chuknagar, on 20th May 1971. They moved around in 2-3 trucks equipped with semi-automatic rifles and light machine guns, and shot dead the Hindus.

I am giving some witness accounts ~

1. On 20th May 20 in 1971, thousands of people took shelter at Chuknagar Bazar, Patkhola ground under Maltia village and on the banks of the River Bhadra. Suddenly, Pakistani troops arrived from Satkhira. They first killed a farmer Chikan Morol, while he was cultivating his paddy field.

2. The Pakistani army detachment was not very large, possibly a platoon or so. Within a few minutes a lively town turned into a city of death.

3. There were bodies over bodies, thousands of bodies. I did not get any space to step out by-passing the blood-stained bodies,’ - said a witness, Anser Ali, as he recalled the memories.

4. Almost 100 people were found dead under the root of the banyan tree at the 'Kali-mondir. Later that tree was cut down for extending the temple’ ~ said another witness.

5. Another witness to the massacre, Shafiqul Islam (principal of
Chuknagar College), said ~ the invading Pakistani troops had taken pos ition on two sides of the local bazaar and started firing, indiscriminately.
Many of those who succeeded in evading the bullets, lost their lives in the stampede of the fleeing crowd," he told BSS.’
The tide of blood was meeting the river. l briefly halted at one place when I saw a baby girl sucking her deceased mother's breast. I was shouting and crying. I will never forget the scene in my life time," he said in tearful eyes.
Local people rescued the baby and called her ‘Sundari Dasi.’ The six- month-old Sundari is now mother of two children and she was passing her days in great hardship.

Mr Umar Khalid has again been denied bail -- not even interim bail for 15 days to assist his mother during a scheduled medical procedure.

Justice Krishna Iyer's dictum was laid down in 1977. It may be perhaps found only in textbooks and presumably not applicable to real cases and real accused.

The Trial Courts seem to think that 'we shall oblige the police and send the accused to jail and let the accused secure bail from the higher Courts (HC and SC).

This is abdication of duty. If the Trial Courts did their work and applied the law, the burden on the High Courts and the Supreme Court will reduce considerably

And so many thousands of under-trials will not languish in prison without charges being framed, without a trial and without a punishment

It is rightly said that 'the process is the punishment'
