The ‘good viruses’ that battle bacteria are called bacteriophages.
In the constant struggle between humans and harmful bacteria, scientists have discovered an unlikely ally – bacteriophages. These unique viruses, often referred to as “good viruses,” play a crucial role in combating bacterial infections. As we delve into the world of bacteriophages, we uncover their fascinating characteristics, their potential as a therapeutic tool, and their significance in the fight against antibiotic-resistant bacteria.
Understanding Bacteriophages
Bacteriophages, or simply phages, are viruses that specifically target and infect bacteria. Their name originates from the Greek word “phagein,” meaning “to devour.” Discovered over a century ago, bacteriophages are the most abundant biological entities on Earth, estimated to outnumber bacteria by a factor of 10 to 1. Their prevalence in nature highlights their critical role in regulating bacterial populations.
The Bacteriophage Lifecycle
Bacteriophages have a unique lifecycle, which consists of two primary stages:
Attachment and Invasion: Phages attach to specific receptors on the surface of bacterial cells. Once attached, they inject their genetic material (DNA or RNA) into the bacterium.
Replication and Lysis: Inside the bacterial cell, the phage’s genetic material takes over the cell’s machinery, instructing it to produce multiple copies of new phages. The bacterium becomes a factory, churning out phages until it reaches capacity, causing the cell to burst (lysis). This releases numerous new phages to infect neighboring bacteria.
Bacteriophages: A Therapeutic Tool
The discovery of bacteriophages has opened up new possibilities for their application as a therapeutic tool, especially in the era of antibiotic resistance. With the emergence of “superbugs” – bacteria that have developed resistance to conventional antibiotics – researchers are exploring alternative approaches to combat these deadly infections. Bacteriophages offer a promising solution.
Narrow-Spectrum Specificity: Bacteriophages are highly specific to certain types of bacteria, targeting only the harmful ones while leaving beneficial bacteria untouched. This specificity makes them an ideal alternative to broad-spectrum antibiotics that may disrupt the body’s natural microbiome.
Adaptive Evolution: Bacteriophages can evolve rapidly to counter bacterial resistance. Unlike antibiotics, which may lose effectiveness over time due to resistance development, phages can “keep up” with bacterial mutations, reducing the risk of resistance.
Biofilm Disruption: Bacteria often form protective biofilms, making them resilient against antibiotics. Bacteriophages have shown promise in penetrating these biofilms and effectively targeting bacteria within them.
Localized Treatment: Phage therapy can be applied topically, allowing for localized treatment of infections, which may reduce the risk of systemic side effects associated with antibiotics.
The Challenges and Future of Phage Therapy
While bacteriophages hold immense potential as a therapeutic tool, several challenges must be addressed to fully harness their benefits:
Regulatory Hurdles: The approval and regulation of phage therapy as a medical treatment vary between countries, hindering its widespread adoption.
Phage Selection: Identifying the most effective phages against specific bacteria and ensuring their safety is a complex process.
Dosing and Delivery: Determining the optimal dosage and mode of delivery for phage therapy requires further research.
Bacteriophages, the “good viruses,” have captivated the scientific community with their potential to combat bacterial infections. As we face the growing threat of antibiotic-resistant bacteria, phage therapy offers a promising alternative for the future of medical treatment. By understanding and harnessing the power of bacteriophages, we may unlock a new era in medicine where these tiny viruses become our allies in the relentless battle against harmful bacteria.

Festival
The Tamil festival of Mattu Pongal 2025 celebrating our diligent cattle.
The auspicious 4-day stretch of Pongal kickstarted yesterday and brings us to the heartening Mattu Pongal celebration today. What is it all about?
With 394.6 million acres of India’s soil being farmland, the special significance cattle holds for us is insurmountable. And that is the sentiment that is honoured with grand celebrations on the occasion of Mattu Pongal. Mattu Pongal is being celebrated today, Wednesday, January 15. The rituals, traditions and customs observed on this day highlight the reverence of animals, particularly in the Tamil culture. While there is a lot of religiosity and routine surrounding the day, at the heart of it, Mattu Pongal is a day when the community gets together to truly thank the cattle for their unmatched contributions across the agricultural spectrum.
Also an important subtext of the festival is the day marking the beginning of the Tamil month of Thai, associated with the harvest of rice and other crops. Coming back to the topic of honouring cattle, the day traditionally involves a series of elaborate rituals, centered around the hallowed cattle.
The day begins with farmers and cattle owners, bathing the cattle with herbal pastes and scents, ensuring they are well-groomed for the whole day’s worth of festivities. The cattle are then thoroughly decorated with tikas, vibrant motifs on their horns, garlands, bells and even colour cloth draped over their bodies. The subsequent puja focuses on seeking blessings for their health and prosperity by paying obeisance to deities like Lord Ganesha and Lord Murugan.
The cattle are then further pampered by being fed concoctions of ghee, sugar, jaggery and rice followed by additional treats like coconuts, sugarcanes and bananas. The absolute highlight of the day however, are the bullock cart races. Friendly in their nature, these are accompanied with music, dance, chants and feasts with the women donning colourful sarees and the men folk turning out in traditional attires like the dhoti.
We wish you all a happy Mattu Pongal!

Dimple Kapadia’s “excellent” natural haircare components are the keys to her most beautiful hair: Egg with onion juice
Celebrities’ haircare secrets are always a mystery; but we’ve got the scoop. Here are some tips from veteran actor Dimple Kapadia, known for her luscious hair.
Ever wondered what the secret to Dimple Kapadia’s ‘glossy and shiny’ locks is? You’re in luck as the Bollywood A-lister shared the haircare tips and tricks she’s picked up over the years in a 2021 interview with Vogue India, and they are pretty much the best hair care advice you will ever get. The best part? Dimple’s inexpensive haircare tips could help you achieve healthy, beautiful locks without breaking the bank.

‘Oil your hair and do not colour it’
Speaking about her ‘glossy and shiny’ hair, the actor credited the ‘habit of oiling’ that started in her childhood, and said, “Oiling goes a long, long way. I oil my hair overnight, then get a head massage with a homemade hair pack, which is a mixture of eggs (5 whites and a whole egg) and a banana. I leave it on for 10-30 minutes and then wash it through with lukewarm water… the habit of oiling was prevalent throughout my childhood, and it helped as I have always had very dry, thick and coarse hair. Without the amount of professional styling I’ve had over the years, it would not look so glossy and shiny.”
‘Onion juice is excellent for the hair’
Dimple, 67, added, “My secret hair oil recipe is a concoction of almond and sandalwood oil as a base, with geranium, rosemary and lavender essential oils. This is the legacy I’ll pass down to my grandchildren – oil your hair and do not colour it… onion juice is excellent for the hair but I think, the safer option is to use the onion extract oils you get now.”
Diet for healthy hair
Dimple’s healthy hair diet included fish that can provide essential nutrients for promoting hair growth and maintaining healthy locks. The actor said that she ‘ate a lot of fish growing up’ as her family lived in a coastal area, adding that ‘really helped’ her hair.
Dimple suggested that you ‘include lots of protein in your diet, eat balanced meals and include seeds and nuts’ to provide your hair with the essential nutrients it needs to stay healthy, strong, and beautiful.
