In a remarkable breakthrough, scientists claim MIT has developed an injectable gel that can regrow damaged nerves and completely restore lost sensation, based on animal studies. According to the reports, this gel is injected into injured nerve sites, where it forms a biological scaffold that encourages nerve fibres to reconnect, while also delivering molecules that prevent scarring and guide regeneration.

Within just a few weeks, test animals reportedly regained nearly full sensation in previously numb areas, suggesting this could be a game-changing therapy for nerve injuries, paralysis, and sensory loss.

Although these results are from early-stage lab studies, the potential is huge: a minimally-invasive treatment that harnesses the body’s own healing power to repair nerves, without the need for complex surgery or implanted wires. If human trials succeed, this technology could transform recovery from spinal cord injury, peripheral nerve damage, and other neurological conditions.

🚨 Warning to All Microbiologists in Pakistan! 🚨
The future of Microbiologists is at serious risk due to the current policies of the Allied Health Professionals Council (AHPC) of Pakistan.

👉 AHPC has decided not to issue professional licenses to Microbiologists.
👉 Without this license, Microbiologists cannot apply for health-related jobs both in Pakistan and abroad (for example, Saudi Arabia MOH or Dataflow applications require an AHPC registration certificate).
👉 The main reason behind this injustice is the lack of proper representation of the Microbiology community within AHPC.
👉 The Microbiologist representative seat has been given to a person from the MLT (Medical Laboratory Technology) background.

⚠️ It’s time to wake up and raise your voice!
Microbiologists deserve fair representation, recognition, and licensing rights in Pakistan.

⚠️ عمر رسیدہ باپ اپنے بچوں کو پہلے سمجھے گئے مقابلے میں کہیں زیادہ خطرناک جینیاتی تبدیلیاں منتقل کر رہے ہیں۔

یہ عمل اولاد میں آٹزم (Autism) اور کینسر (Cancer) کے خطرات کو نمایاں طور پر بڑھا دیتا ہے، نئی تحقیق سے انکشاف ہوا ہے۔

نئی تحقیق سے معلوم ہوا ہے کہ عمر رسیدہ مردوں کے بچوں میں جینیاتی بیماریوں کے امکانات زیادہ ہوتے ہیں، جس کی ایک بڑی وجہ "Selfish S***m" یعنی "خودغرض نطفہ" ہے۔

جدید جینوم سیکوینسنگ (Genome Sequencing) پر مبنی ایک بڑی تحقیق سے پتا چلا کہ جہاں 30 سال کے مردوں کے تقریباً ہر 50 میں سے ایک نطفہ نقصان دہ جینیاتی تبدیلی رکھتا ہے، وہیں 70 سال کی عمر تک یہ شرح ہر 20 میں سے ایک تک پہنچ جاتی ہے۔

یہ تغیرات صرف بڑھاپے کی وجہ سے نہیں بلکہ ایسی مخصوص تبدیلیوں سے پیدا ہوتے ہیں جو نطفہ بنانے والے خلیوں (S***m-producing stem cells) کو تیز رفتار نشوونما کا فائدہ دیتی ہیں۔ نتیجتاً یہ خلیے بڑھتے جاتے ہیں اور سپرمی خلیوں پر غلبہ حاصل کر لیتے ہیں۔

یہ “خودغرض” جینیاتی تبدیلیاں خاص طور پر دماغی نشوونما (Neurodevelopment) اور کینسر کے خطرے سے وابستہ جینز کو متاثر کرتی ہیں، اور ان کی تعداد عمر کے ساتھ تیزی سے بڑھتی جاتی ہے۔

تحقیق میں ایسے 40 سے زائد جینز کی نشاندہی کی گئی جو اس اثر کا باعث بن سکتے ہیں، جن میں وہ جینز بھی شامل ہیں جو آٹزم اور سنگین نشوونمایی امراض سے منسلک ہیں۔

دلچسپ بات یہ ہے کہ جہاں سگریٹ نوشی اور شراب نوشی جیسے مضر عادات خون کے خلیوں میں تغیرات کو بڑھاتی ہیں، وہیں نطفہ ان بیرونی عوامل سے بڑی حد تک محفوظ رہتا ہے۔

یہ انقلابی تحقیق اس بات کو واضح کرتی ہے کہ والد کی عمر بھی اتنی ہی اہم ہے جتنی والدہ کی عمر — مستقبل کی نسلوں کی صحت اور جینیاتی خطرات کے تعین میں۔

History has just been made: the world’s first baby has been born from an embryo created almost entirely by IVF robots. 🤖👶

Using advanced automation, robots performed the delicate process of injecting s***m into an egg and monitoring embryo development—tasks once requiring the steady hands of expert embryologists. The embryo was then implanted into a mother, who has now delivered a healthy baby.

This breakthrough could transform fertility treatment by making IVF more accessible, precise, and consistent worldwide. But it also raises big questions: How far should we let machines shape the future of human life?

We’re witnessing the dawn of a new era where science, robotics, and humanity intersect in the most profound way possible.

🦠Viruses teaming up? Researchers just captured a tiny virus clinging to another for survival.

For the first time, scientists have captured a virus hitching a ride on another virus, a form of direct viral cooperation never seen before.

Using a powerful electron microscope, researchers observed a satellite virus physically attached to the “neck” of a helper virus, both of which infect Streptomyces bacteria.

The satellite virus lacks the genetic tools to reproduce on its own, so it clings to the helper virus to ensure they invade the same bacterial cell together — essentially piggybacking into the host to survive.

In examining environmental samples, researchers found that about 80% of helper viruses carried one of these passengers, with many others showing marks from recent attachments.

Genetic analysis confirmed the satellites were missing replication genes, making their strategy one of necessity. This discovery challenges long-held assumptions in virology and suggests that past samples once dismissed as “contaminated” may have actually held evidence of this viral teamwork. It’s a microscopic reminder that even viruses sometimes depend on partners to get ahead.

As we age, many of us start to lose our “inner GPS.” We forget where we parked, how to get back from a new café, or even where we left our keys. But why? And why do some people seem immune to this decline? Stanford scientists may have found the answer. In a groundbreaking study, they discovered that aging disrupts the brain’s internal navigation system, the medial entorhinal cortex, which functions like a biological GPS. In older mice, the neurons that map space, called grid cells, became unstable and confused, causing them to get “lost” in familiar environments.
But here’s the twist: not all old brains failed. A few mice, nicknamed “super-agers,” retained the sharp, youthful firing patterns of their younger counterparts. These super-agers navigated just as well as young mice, their mental maps staying perfectly aligned. Genetic analysis revealed clues to this resilience. The team found 61 genes that could protect against cognitive decline, one of them, Haplin4, may help maintain the brain’s structure and keep neural circuits stable with age. This research challenges the belief that memory decline is inevitable. It suggests that some brains are genetically wired to resist aging and that understanding those protective mechanisms could unlock new ways to preserve memory in humans.
