AI in peer review should be a second reader, not a judge

I have often wondered why, among three reviews of the same biomedical research manuscript, one reviewer may dismiss nearly everything the authors have done, another may offer a moderate assessment, and a third may strongly favor publication. Human review remains…

I have often wondered why, among three reviews of the same biomedical research manuscript, one reviewer may dismiss nearly everything the authors have done, another may offer a moderate assessment, and a third may strongly favor publication. Human review remains essential, but human judgments can vary widely. Some disagreement is useful because reviewers notice different things. In other cases, the differences may reflect misunderstanding, fatigue, disciplinary preference, or bias. The …

AI in scientific writing: Assistance is not authorship

Most scientists I know have several unfinished manuscripts at any given time. I am no exception. Some of mine concern recent work; others are based on research completed years ago, and, in a few cases, decades ago. I vividly remember…

Most scientists I know have several unfinished manuscripts at any given time. I am no exception. Some of mine concern recent work; others are based on research completed years ago, and, in a few cases, decades ago.

I vividly remember a senior colleague at the National Institute of Nutrition who served as my supervisor for a couple of years. He would often show me, with great enthusiasm, a stack of over …

Frontier AI oversight must match real-world risk

Should frontier AI be allowed to grade its own homework?

In a recent Science editorial, Thorsten Holz makes an important point: Claims about the capabilities and safety of frontier AI should not rest solely on assurances from the laboratories developing these systems. Some degree of independent verification is reasonable. The more difficult question is how much oversight is justified by the evidence. Comparisons are increasingly being made between frontier AI …

Patent before publication without limiting open science

"Academia produces knowledge brilliantly. It distributes it appallingly," Professor Dorina Buda wrote recently on LinkedIn. The statement made me pause because it brought back two experiences from nearly a decade apart. Both involved the same molecule, peroxynitrite, a peroxy isomer…

“Academia produces knowledge brilliantly. It distributes it appallingly,” Professor Dorina Buda wrote recently on LinkedIn.

The statement made me pause because it brought back two experiences from nearly a decade apart. Both involved the same molecule, peroxynitrite, a peroxy isomer of nitrate. The first occurred when I knew virtually nothing about patents. The second came after I had worked as a patent examiner at the U.S. Patent and Trademark Office …

Why so few scientists serve in Congress

When Neil H. Shubin assumed the presidency of the National Academy of Sciences, he called for the NAS to speak with greater speed and reach at a time when science is increasingly contested in public life.

That call is timely. But even the clearest scientific advice can be ignored when too few people trained in science and medicine take part in making laws and setting national priorities.

Scientific advice is essential. …

AI fabricated references threaten medical evidence

Generative AI systems can create references to papers that do not exist and make them look real. In medicine, a fabricated or poorly verified reference is not simply a bibliographic error. It weakens the chain of evidence on which reviews, guidelines, teaching, and clinical judgment may depend.

A recent article by Topaz and colleagues in The Lancet highlights an important and growing threat to scientific integrity: the increasing appearance of …

Ethylene is one of the simplest organic molecules, yet it has remarkably different meanings in plants and animals. I first became interested in ethylene during my predoctoral years because of its familiar role in fruit ripening. My interest took a different direction during my early research years at Louisiana State University and later at Southern University, when I began examining how ethylene may arise through oxidative chemistry and its possible …

Recent discussions about the employment prospects of PhD graduates in India prompted me to reflect on a broader question that I have considered for many years. India has expanded higher education dramatically over the past several decades, including medical education, doctoral training, and other professional programs. Yet expansion alone does not automatically translate into educational quality, research capacity, clinical excellence, or meaningful career pathways for highly trained graduates. The question …

Recent discussions surrounding aging and scientific innovation have raised important questions about how scientific creativity should be measured. A recent article in Science approached this issue primarily through bibliometric and disruption-based analyses, perspectives that were subsequently discussed and amplified in other outlets, including Nature.

Still, scientific creativity may not always be fully captured through disruption metrics or bibliometric patterns alone, a concern raised in recent responses discussing the limitations …

Paid peer review is overdue in academic publishing

For many years, peer review has been an expected but largely invisible part of academic life, undertaken quietly, without compensation, and often without formal recognition. In my experience, peer review requests now arrive almost weekly, often competing with teaching, mentoring, and administrative responsibilities. While not all are accepted, many are taken on out of a sense of professional obligation, even when time is limited. This work has been sustained by …

One of the most difficult moments in scholarship is deciding when a piece of work is ready to leave the desk of the author and enter the public domain. Peer review continues to rely almost entirely on voluntary scholarly labor, even as the academic environment supporting it becomes increasingly strained.

Over the past several years, many faculty in higher education in the United States, whether at public or private institutions, have …

Philanthropy for scientific research is underused

I often wonder why giving has so little to do with how much one has. A millionaire may hesitate to part with even a few thousand dollars for a person in need, while someone with only a modest savings may readily give away a meaningful share of it for a good cause. Clearly, something deeper is at work than what we see outwardly. This raises an important question: why does …

I sometimes find myself reflecting when my well-cited journal articles begin to show a decline, whether gradual or sudden. In academic medicine, citations have become a form of currency, used not only to trace ideas but also to measure worth. Yet what gets cited is not always what matters most. In biomedical research, citations support arguments and help measure impact. In principle, they show how knowledge develops over time. In …

In 1988, an unusual scene unfolded at the French National Institute of Health and Medical Research Unit 200 in Clamart, France. The then editor of Nature, John Maddox, arrived at Jacques Benveniste’s laboratory accompanied by investigator Walter Stewart and the professional magician and skeptic James Randi. Their task was not to perform tricks but to examine an extraordinary scientific claim: that biological activity might persist even when no molecules of …

Every research mentor eventually faces a difficult question: What, and who, will continue when the work is no longer theirs to carry forward?

We often speak about mentoring, yet the dilemma of mentorship is rarely addressed directly. Perhaps it lies at the intersection of responsibility and uncertainty. Mentorship is often imagined as guidance freely given, with apprenticeship unfolding naturally. In modern academic life, however, the laboratory is shaped not only by …

William A. Pryor, whose intellectual rigor and scientific voice shaped generations of researchers and the broader world of free radical biology and medicine, often told me something I have never forgotten. Only later did I understand that it was really about cognition.

Emotional contagion and crowd psychology are powerful forces that shape human behavior in large gatherings. In India, where collective identity and reverence for public figures often run deep, emotional responses within crowds may take on added intensity. This reflection draws on an incident from Tamil Nadu to illustrate how collective emotion can sometimes override proportion and common sense, with implications for community safety and well-being.

This may sound amusing today, but …

Human milk contains more than nutrients; it carries a quiet, evolutionary intelligence expressed through chemistry. It is not conscious thought, but the slow wisdom of evolution written into molecules that nourish, protect, and guide.

Among its most remarkable ingredients are the human milk oligosaccharides (HMOs). These complex sugars, present at around 0.5 to 1.5 g/dL, are not there to feed the infant directly.

They move through the stomach and small intestine largely …

I cannot claim to have been the one who nurtured our garden. That credit belongs to my wife. She is the one who waters the plants faithfully and notices when something needs care.
