The WHO have been hugely misreported by the media. Mike Ryan said that if we develop a safe and effective vaccine for COVID19 we also have to deploy it. We can do this. If we vaccinate enough people to eradicate this virus, it is a "beacon of hope" for the way we care about our world citizens.

Mike Ryan points out that we have a safe and effective vaccine for measles but haven't eliminated it from the world although we know how to do this.

[We have eradicted it from the Americas, last case July 2015 in Brazil. Measles elimination in the America]

Though coronavirus is a new name for much of the world, microbiologists have worried about it for half a century. It is in the same family as the common cold virus but with the right mutation it can be deadly to those with risk factors for respiratory diseases because it is common like the common cold.

To microbiologists, the world is filled with pathogens so predicting the next plague when nature is always out to kill us can verge on paranoia; instead we are fortunate most new crises never happen. Let's hope that worry about global spread of the multi-resistant pathogen Stenotrophomonas maltophilia fizzles out also.
A new paper has implicated a physiologic mechanism in vegetation as a cause for Arctic warming.

The "greenhouse effect" is well-known by now, water vapor that plants emit during photosynthesis serves to lower land surface temperature, similar watering the yard on a hot day, but it can lead to a rise in air temperature.

The new paper finds that the Arctic temperature rises when the moisture released by plants is reduced due to the increase of carbon dioxide (CO2 ) in the atmosphere. The increase in atmospheric CO2 concentration closes the pores (stomata) of plants in high-latitude areas and reduces their transpiration, which they find ultimately accelerates Arctic warming. 
Conservation groups have frequently sued the U.S Army Corps of Engineers claiming that government scientists do not "properly" evaluate the environmental impacts of its plans to mitigate flood risk.
When states and nations began to implement forced lockdowns to combat COVID-19, the SARS-CoV-2 coronavirus that has now killed 20,000 more people than the flu did two years ago, there was relatively little mention of mental health. For those who wanted to stay home and learn to bake bread, it was a paid vacation, but for those more susceptible to psychological stress it is a risky time.
During the SARS-CoV-2 pandemic, when disease epidemiologists want to be taken seriously by the public, they face an uphill battle. Blocking their progress are epidemiologists who casually link everything to diseases, often using food frequency questionnaires which have no scientific legitimacy.

Young people who are “hooked” on watching fantasy or reading science fiction may be on to something. Contrary to a common misperception that reading this genre is an unworthy practice, reading science fiction and fantasy may help young people cope, especially with the stress and anxiety of living through the COVID-19 pandemic.

Anxiety-prone people can blame serotonin cleanup proteins gone awry in their amygdala, according to research in marmosets recently published in JNeurosci. Targeting the amygdala with anti-anxiety medication could provide quicker relief.

The same event or set of life circumstances could send one person into the depths of anxiety or despair while leaving another unaffected. This distinction, called trait anxiety, arises from the proteins involved in serotonin signaling, a neurotransmitter implicated in anxiety and depression.

A person with Type 2 diabetes is three times more likely to break a bone than a nondiabetic. Since the number of people with diabetes is increasing rapidly in the United States, skeletal fragility in patients with Type 2 diabetes is a growing, but little-known, public health issue.

Usually poor bone density is the culprit behind fragile bones, but that is not the case with Type 2 diabetics, who tend to have normal to high bone density. Yet, they still suffer from fractures at an alarming rate. Nobody knows why.

The offer of Ph.D. positions in Physics at the University of Padova has opened just a few days ago, and I wish to advertise it here, giving some background on the matter for those of you who are interested in the call or know somebody who could be.

The Ph.D. in Italy In Italy, Ph. D.s last three years (the duration can be extended but this is not recommended). Courses start with the first academic semester, so the calls typically open in the spring, and admission tests are run in the summer. The system is not too different from that of other countries, but there are peculiarities of which you might want to be aware.
