Mind the Anticipatory Gap: Genome Editing, Value Change and Governance

Posted by in categories: biotech/medical, ethics, governance, mobile phones

I was recently a co-author on a paper about anticipatory governance and genome editing. The lead author was Jon Rueda, and the others were Seppe Segers, Jeroen Hopster, Belén Liedo, and Samuela Marchiori. It’s available open access here on the Journal of Medical Ethics website. There is a short (900 word) summary available on the JME blog. Here’s a quick teaser for it:

Transformative emerging technologies pose a governance challenge. Back in 1980, a little-known academic at the University of Aston in the UK, called David Collingridge, identified the dilemma that has come to define this challenge: the control dilemma (also known as the ‘Collingridge Dilemma’). The dilemma states that, for any emerging technology, we face a trade-off between our knowledge of its impact and our ability to control it. Early on, we know little about it, but it is relatively easy to control. Later, as we learn more, it becomes harder to control. This is because technologies tend to diffuse throughout society and become embedded in social processes and institutions. Think about our recent history with smartphones. When Steve Jobs announced the iPhone back in 2007, we didn’t know just how pervasive and all-consuming this device would become. Now we do but it is hard to put the genie back in the bottle (as some would like to do).

The field of anticipatory governance tries to address the control dilemma. It aims to carefully manage the rollout of an emerging technology so as to avoid the problem of losing control just as we learn more about the effects of the technology. Anticipatory governance has become popular in the world of responsible innovation and design. In the field of bioethics, approaches to anticipatory governance often try to anticipate future technical realities, ethical concerns, and incorporate differing public opinion about a technology. But there is a ‘gap’ in current approaches to anticipatory governance.

Papers: I have published quite a number of academic papers in the past 7–8 years

Posted by in category: health

It has gotten to the point now that I find myself trying to make sense of them all. If you were to read them, what would you learn about me and my beliefs? Are there any coherent themes and patterns within these papers? I think there are and this is my attempt to hunt them out. I’m sure this will seem self-indulgent to some of you. I can only apologise. It is a deliberately self-indulgent exercise, but hopefully the thematic organisation is of interest to people other than myself, and some of the arguments may be intriguing or pique your curiosity. I’m going to keep this overview updated.

Reading note: There is some overlap in content between the sections below since some papers belonged to more than one theme. Also, clicking on the titles of the papers will take you directly to an open access version of them.

An electronic microemulsion phase emerging from a quantum crystal-to-liquid transition

Posted by in categories: particle physics, quantum physics

Competition between different possible ground states of strongly correlated electron systems can lead to the emergence of mixed states called microemulsions. Now this phenomenon is reported at the meltingion of a Wigner crystal.

In the world of tiny particles and quantum physics, scientists often study how electrons—the fundamental particles that carry electricity—behave under different conditions. When electrons interact strongly with each other, they can form various states of matter, much like how water can turn into ice or steam. Sometimes, these states compete, leading to complex and fascinating patterns. One such pattern is called a microemulsion phase, where tiny regions of different electron states mix together, creating a kind of quantum “patchwork quilt.”

In this study, researchers explored a special material called a MoSe₂ monolayer, which is an ultra-thin layer of atoms that can host electrons. By cooling this material to extremely low temperatures and using advanced light-based techniques, they observed something remarkable: aion between two electron states—a rigid Wigner crystal (where electrons are locked in place) and a flowing electron liquid. During thision, the electrons formed a microemulsion phase, blending crystal-like and liquid-like regions in a unique, self-organized pattern.

Cancer diagnoses rising faster in women, especially those under 50: Report

Posted by in category: biotech/medical

Women are now being diagnosed with cancer more often than men in certain age groups, according to a new report from the American Cancer Society.

Among adults aged 50–64, cancer rates are slightly higher in women, and women under 50 are almost twice as likely as men in the same age group to receive a cancer diagnosis.

The report, released Thursday, found that while deaths continue to decrease, troubling racial disparities persist, with white Americans more likely to survive cancer than other groups.

20 Years in the Making: Scientists Unveil Breakthrough Anticancer Weapon

Posted by in categories: bioengineering, biotech/medical, business, education, law

A new twist on a decades-old anticancer strategy has demonstrated significant potential against various cancer types in a preclinical study conducted by researchers at the Perelman School of Medicine at the University of Pennsylvania

The University of Pennsylvania (Penn) is a prestigious private Ivy League research university located in Philadelphia, Pennsylvania. Founded in 1740 by Benjamin Franklin, Penn is one of the oldest universities in the United States. It is renowned for its strong emphasis on interdisciplinary education and its professional schools, including the Wharton School, one of the leading business schools globally. The university offers a wide range of undergraduate, graduate, and professional programs across various fields such as law, medicine, engineering, and arts and sciences. Penn is also known for its significant contributions to research, innovative teaching methods, and active campus life, making it a hub of academic and extracurricular activity.

Enhancing NAD+ Efficiency by Energizing Sirtuins

Posted by in category: biotech/medical

Researchers publishing in Physical Review X have discovered compounds that can double the efficiency of the sirtuin SIRT3 in processing NAD+.

Looking for a new way to boost enzymes

The researchers begin their paper by noting that most drugs administered to people are geared towards inhibition of particular enzymes in order to treat a disease. In this case, however, the goal is the opposite: to boost the function of an enzyme, thereby boosting a healthy phenotype rather than battling back a diseased one.

GLP-1 Drugs Offer Brain Benefits but May Pose Other Health Risks

Posted by in categories: biotech/medical, health, neuroscience

Summary: A study analyzing data from over 2 million veterans found that GLP-1 receptor agonists, popular weight-loss drugs like Ozempic and Wegovy, provide significant neurological and behavioral health benefits, including reduced risks of addiction, Alzheimer’s, and dementia. However, they also pose risks for pancreatitis and kidney conditions, emphasizing the need for careful monitoring.

The drugs mimic hormones that curb appetite and aid weight loss but may act on brain regions tied to impulse control and inflammation, explaining their broad effects. Researchers stress that while the benefits are modest, they may be impactful for conditions with limited treatment options, highlighting both their potential and limitations.
