Paul MatzkoTake a second and think about how you heard about the recent train derailment in Ohio, which created a giant cloud of toxic chemicals and forced a mass evacuation. It’s the plot ofWhite Noise come to life.If you ’re reading this, then odds are you first heard about the crash online. But if you’re one of the dwindling number of people who rely on local newspapers and tv station for news, then you’ll likely have seen stories that mostly just repeat official statements from the authorities.“If you are in this red zone that is on the map, and you refuse to evacuate, you are risking death,”said PA Go...

Blood Pressure Control Reverses Expansion of Perivascular Spaces in the Aging Brain
Study data here shows that age-related enlargement of perivascular spaces in the brain is to some degree driven by raised blood pressure, and reversible given control of blood pressure. As the researchers note, this enlargement is a part of the issues that lead to a reduced clearance of metabolic waste from the brain in later life. This reduced clearance is likely an important factor in the development of neurodegenerative conditions. All told, the raised blood pressure of hypertension is one of the more important ways in which deeper causes of aging are converted to tissue dysfunction and outright structural damage throug...

Senators Bennet and Collins Have Their Hearts in the Right Place, But Their Eyes on the Wrong Target
Jeffrey A. SingerSenator Susan Collins (R ‑ME) wrote anop ‐ed for Seacoastonline this week expressing her concerns about skyrocketing drug overdose deaths. According to the most recentdata from the National Center for Health Statistics, 90 percent of opioid ‐related overdose deaths involve illicit fentanyl, and 15 percent involve diverted prescription pain pills. In her column, Senator Collins expressed pride in a proposal aimed at reducing overdoses that she co‐sponsored with Senator Michael Bennet (D‑CO). Unfortunately, while the legisla tion was well‐intended, it placed too much emphasis on educ...

Antibacterial Peptide Spray Safe for Use on Wounds
Researchers at Chalmers University of Technology in Sweden have developed an antimicrobial spray that is safe to use on wounds and in the body, including as an antimicrobial coating on implantable or in-dwelling devices, such as urinary catheters. The technology is not based on harsh chemical antiseptics or antibiotic drugs that could aggravate tissue or result in microbial drug resistance. Instead, it employs antimicrobial peptides that are naturally produced by the mammalian immune system. These peptides are effective in killing microbes, but are typically considered too unstable for use as an antiseptic. However, these ...

A paradigm shift in paradigm shifts
Researchers who present radical new theories are often ridiculed and their work rejected despite the evidence they provide because the new theory upsets the received wisdom or is so outside what is considered to be the accepted paradigm. But there is a third way forward that could allow radical new thinking to emerge without it being lambasted unnecessarily so that it can be judged wholly on its merits.
Writing in the International Journal of Management Concepts and Philosophy, a team from Australia and the UK discuss two well-known theories that too many years to be accepted into the mainstream. The first was the medical ...

The dark side of medicine: How the profession can become an emotionally and psychologically manipulative relationship
To the quiet physician who keeps her head down and powers through her days while secretly calculating the ratio of BS-to-be-tolerated versus time-to-retirement: I have some tough love for you. You are in a toxic relationship. How do I know? I’ll let you in on my secret: I was in a psychologically and emotionally manipulative

Flexible Sensors Detect Heavy Metals in Sweat
Researchers at the University of São Paulo in Brazil, along with collaborators in Germany and Sweden, have developed a flexible sensor that can detect heavy metals in sweat, an easily obtainable bodily fluid. Heavy metals, such as lead or cadmium, can cause serious toxicity if they accumulate in the body, but detecting the concentration of such metals in biological samples requires expensive laboratory equipment and skilled staff. To address this, these researchers have created a flexible sensor that is easy to use and which can detect metals in sweat samples before transmitting the results to a smartphone. The technology...

Does Mitochondrial Dysfunction Meaningfully Contribute to the Development of Atherosclerosis?
Mitochondria are the power plants of the cell, producing the chemical energy store molecule ATP, but are also integrated into a wide range of fundamental cellular processes. Mitochondrial function declines with age, likely an important contribution to age-related declines in energy-hungry tissues such as the brain and muscles. It is also known that mitochondrial dysfunction can provoke chronic inflammation via the mislocation of mitochondrial DNA into parts of the cell where it will act as a damage-associated molecular pattern. This upregulation of inflammatory signaling is a reasonable proposal for the way in which mitoch...

Extracellular Vesicles in the Development of Neurodegenerative Conditions
A broad discussion of extracellular vesicles is really a broad discussion of cell communication, as much of the traffic of molecules between cells is carried inside vesicles. Researchers here discuss what is known of the roles played by vesicle-mediated communication in neurodegenerative conditions, still a very broad topic. One of the noteworthy contributions is that this traffic of vesicles enables the spread of prion-like altered and misfolded proteins, such as tau and α-synuclein, that are capable of seeding the generation of more such harmful molecules in the destination cell. Whether there are ways to selectively pr...
