A million and a half students, even very young ones, took to the streets Friday March 15th, in two thousand cities around the world, for the climate, responding to a Greta Thunberg’s call. Greta is a 16-year-old student in Stockholm: “I will not stop. Not until greenhouse gas emissions have fallen below the alarm level.” Considering the great support she had, it would seem that students were not waiting for anything else, with great outcry of the ecologists of various tendencies, who have for years repeated the same call, without being able to arouse mass movements of this magnitude.

There is no doubt that we are on the verge of great changes. The automotive industry — by far a leading industry in the world economy — is about to collapse, because it has not been able to innovate in time, and now it does not in fact have ready solutions, to satisfy a market that no longer intends to exchange mobility with health. Such imminent collapse will not do any good to economy. It will also offer vampire rulers new opportunities to increase the taxation, already exorbitant in many countries. And no one seems to realise that if producers die as a social category, consumers will soon die too, as they are the same people. There is no doubt, moreover, that the ruling politicians, more and more void of any basic culture, will find many ways to manage what Serge Latouche (in his essay on the so-called “happy de-growth”) called “inevitable social problems following de-growth”.

Childhood trauma such as neglectful parenting causes physical scarring to the brain and increases the risk of severe depression, a new study has found.

For the first time, scientists have linked changes in the structure of the brain both to traumatic early-years experiences and poor mental health in later life.

Published in the Lancet, the study found a “significant” link between adults who had experienced maltreatment as children with a smaller insular cortex, part of the brain believed to help regulate emotion.

The newest FDA-approved medication to treat severe depression, a nasal spray based on the anesthetic (and misused hallucinogenic party drug) ketamine, will soon be available to veterans treated within the Department of Veterans Affairs.

In a move that may help thousands of former service members with depression that has not improved with other treatments, VA officials announced Tuesday that the department’s doctors are now authorized to prescribe Spravato, the brand name for esketamine, a molecular variation of ketamine.

The decision to offer a drug hailed by many as a breakthrough in treatment for its speedy results — often relieving symptoms in hours and days, not weeks — shows the VA’s “commitment to seek new ways to provide the best health care available for our nation’s veterans,” Secretary Robert Wilkie said in a release.

A team of researchers at the Rochester Institute of Technology invented a “toilet seat-based cardiovascular monitoring system” that could help hospitals monitor patients for risk of congestive heart failure — a toilet, in other words, that detects whether your heart is about to give out.

“This system will be uniquely positioned to capture trend data in the home that has been previously unattainable,” reads the paper, published in the journal JMIR Mhealth Uhealth.

Integrated into the seat is a device that measures heart rate, blood pressure, and blood oxygenation levels. Algorithms will take in all that data and notify health practitioners if the patient’s condition deteriorates.

It’s cliché to describe something very noisy as “louder than a jet engine.” But supersonic jet engines, like those powering fighters flown by the U.S. military, are so much louder than regular jet engines that scientists have a special term for their sound—” broadband shock-associated noise.”

Now, a team of faculty and students from the Department of Aerospace Engineering at the University of Kansas will design and test to cut noise from supersonic military jets. The U.S. Department of Defense’s Strategic Environmental Research and Development Program (SERDP), the DoD’s environmental science and technology program, is supporting a one-year, $200,000 effort at KU, with the potential to expand that support in the years ahead.

“This project will test ideas to reduce from supersonic military aircraft,” said Z.J. Wang, Spahr Professor of Aerospace Engineering at KU, who is heading the new effort. “At the moment, the noise is so loud that it affects the health of personnel working in close proximity to the aircraft and people living close to the military base. This is a challenging problem, and we’ve suggested some novel ideas which have potential.”

Imagine that… The earth is round.


Many people view pollutants and pathogens as separate causes of illness. However, recent research indicates that the two can interact, changing how people and animals respond to infectious diseases. According to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, environmental pollutants appear to weaken the immune system, reduce vaccine efficacy and increase pathogen virulence.

More than 20 years ago, researchers showed that exposing mice to low levels of a dioxin called 2,3,7,8-tetrachlorodibenzo–p-dioxin made them more susceptible to influenza virus. Since then, several studies have suggested that other chemicals, such as perfluorooctanoic acid, mercury and arsenic, can also alter animals’ immune responses and decrease their resistance to infectious diseases. And epidemiological studies in humans have linked chemical exposure in the womb to a child’s increased risk of infectious disease. However, scientists are only now beginning to unravel how this happens, Senior Editor Britt Erickson writes.

Compounds called per- and polyfluoroalkyl substances (PFAS) are widely used in household products, such as food packaging, nonstick products and cleaners. Researchers have linked elevated concentrations of some PFAS in mothers’ blood to reduced responses to vaccinations and more illnesses in their children. Similarly, arsenic exposure in the womb has been associated with decreased levels of antibodies against diphtheria in vaccinated Bangladeshi children. Evidence also suggests that some chemicals, such as zinc or lead, may contribute to the rise of multidrug-resistant strains of methicillin-resistant Staphylococcus aureus (known as MRSA). Such interactions are complex and will require more interdisciplinary research in environmental health and infectious disease, Erickson writes.
