This CT scan belongs to a 73-year-old woman in whom doctors discovered a 30-year-old calcified fetus.

Known medically as a lithopedion, this rare condition occurs when a fetus dies during pregnancy and is not expelled from the body. Instead, the body responds by surrounding the remains with calcium deposits, effectively preserving the fetus in a calcified form. This usually happens when fetal death occurs during the second trimester and the body does not recognize or respond to the loss, allowing the fetus to remain in the abdominal cavity undetected for years.

This is an important and nuanced question, " why indian people are not much interested in Medical Research", rather the issue is more about systemic barriers, infrastructure gaps, and prioritization challenges that have historically limited India’s contribution to global cutting-edge medical research relative to its potential.

Here’s a breakdown of the key reasons:

1. Low Funding for Research
• GDP Allocation: India spends only around 0.7% of its GDP on R&D, compared to ~2–3% in countries like the US, China, or South Korea.
• Medical Research Gets Less: Within that, medical research receives only a small slice. Most funding goes to defense or space.

🏥 2. Clinical Burden > Research Focus
• Doctors in India are overburdened with clinical work due to the high doctor-patient ratio. For example:
• Government hospitals are overcrowded.
• Private hospitals prioritize service delivery and profits.
• This leaves little time or incentive for research activities.

🎓 3. Academic & Institutional Weakness
• Many Indian medical colleges lack a research culture.
• MBBS and MD/DM programs focus heavily on rote learning and exams, not critical thinking or scientific inquiry.
• Faculty promotions have historically not been based on the quality of published research.

🧠 4. Brain Drain
• Many of India’s brightest minds go abroad (especially to the US, UK, or Europe) for PhDs, postdocs, and medical training — and stay there.
• India produces talent, but often doesn’t retain it.

💰 5. Lack of Industry-Academia Collaboration
• In countries like the US, pharmaceutical and biotech companies collaborate extensively with universities and hospitals.
• In India, such partnerships are rare and often limited to clinical trials, not innovation.

⚖️ 6. Regulatory and Bureaucratic Hurdles
• Approval for trials, ethics clearance, and research grants is slow and often unpredictable.
• Clinical trials have faced controversy and public mistrust, leading to restrictive policies post-2013.

🌍 7. Global Inequity in Recognition
• Research done in India often gets less visibility in top journals.
• Language, funding, and publishing barriers make it harder to participate in high-impact global discourse.

But — It’s Not All Negative:

India has made progress in some areas:
• ICMR, AIIMS, CSIR, and DBT fund important research.
• COVID-19 accelerated domestic research capabilities (vaccines, epidemiology, etc.).
• Institutes like NIMHANS, Tata Memorial, and CCMB do publish high-quality research.
• Startups in biotech (like Bharat Biotech or Serum Institute) are growing.

🔑 So, Why the Perception?

It’s a combination of:
• Structural challenges
• Underfunding
• Lack of prioritization
• Low visibility of existing work

But there is interest in medical research in India. What’s missing is a national strategy to support, scale, and retain it.

NATIONAL STRATEGY :-

🧱 1. Boost Investment in Medical R&D

National Level:
• Increase public health R&D spending from

The posterior cord of the brachial plexus gives rise to five branches: the upper subscapular nerve, thoracodorsal nerve (also known as middle subscapular nerve), lower subscapular nerve, axillary nerve, and radial nerve. These nerves innervate muscles in the shoulder and upper arm, as well as providing sensory innervation to the posterior arm, forearm, and hand .

The preauricular sulcus is a bony groove found on the inferior aspect of the ilium (hip bone) near the sacroiliac joint. It is often described as a characteristic feature of the female pelvis, appearing in about 20% of women. The sulcus can vary in size and depth, from a slight concavity to a deep groove with overhanging edges.

Location:
The preauricular sulcus is located on the inferior aspect of the ilium, which is the upper part of the hip bone.

It's situated near the sacroiliac joint, which connects the ilium to the sacrum (the triangular bone at the base of the spine).

It's often described as being adjacent to the inferior surface of the sacroiliac joint.

Appearance:

In females: The sulcus is often described as being deeper and having more clearly demarcated edges.

In males: It is usually shallow with open sides.
The sulcus can vary in size and depth, even within a single s*x.

It can range from a slight concavity to a deep groove with overhanging edges.

Use in S*x Estimation:

The preauricular sulcus is sometimes used as a tool in forensic anthropology and archaeology to help estimate the s*x of an individual based on skeletal remains.

However, it's not a perfect indicator of s*x, and other features of the pelvis are also considered.

Studies have shown that the sulcus is not always present in females and can be present in some males .

Age and other factors can also influence the development of the sulcus .

Therefore, it's important to consider multiple features when estimating s*x from the pelvis .

Science Corporation, a biotech startup co-founded by a former Neuralink executive, has announced a significant breakthrough in brain-computer interface technology, restoring eyesight in legally blind patients. In preliminary clinical trials, patients who had lost their central vision due to conditions like age-related macular degeneration regained the ability to read and recognize faces after receiving retina implants from Science Corp. CEO Max Hodak, previously president of Neuralink, emphasized that this is the first known instance of patients being able to fluently read after losing their sight. The device, named Prima, is a small, photovoltaic chip surgically implanted under the retina. It works by pairing with special glasses equipped with a camera that projects near-infrared light onto the chip. This light powers the device and transmits visual data, which is converted into electrical signals that stimulate the remaining retinal neurons, sending visual information to the brain and restoring basic sight. The results from a trial of 38 patients have been promising, with some participants gaining the ability to read letters, read parts of books, and even complete a crossword puzzle. On average, participants saw at an acuity of 20/160 after one year, although five saw no improvement. While the device has shown promise, it doesn’t offer color vision and raises some questions about image magnification. Despite these limitations, the results offer hope for future advances in retinal prosthetics and vision restoration.
