Electric cars are being artificially bolstered by government mandates and subsidies and are doing little to reduce emissions because the electricity they need is overwhelmingly not solar, nuclear, or hydroelectric.

What would help are batteries that aren't stuck in the 20th century, like lithium-ion, which cost so much to replace that one Tesla owner blew up his car with dynamite rather than a cost for new batteries that was 50 percent of the original purchase price. And they can be dangerous.

Lithium-ion explosion risk

COVID-19 vaccines have shown to be effective at preventing vaccines but the big win for public health is reduced effects if you get it anyway. If you don't have co-morbidities your relative risk is very low but if you do have them, every precaution is worth taking.

The vaccines come in many forms but two of note are the Janssen COVID-19 vaccine (Ad26.COV2.S) and Pfizer-BioNTech (BNT162b2), distinct because Janssen only requires one dose.  And the latter made "mRNA" part of the cultural lexicon. 

Which one led to fewer hospitalizations? They were both outstanding but there is a winner.

In the quest to create more social justice and equity, a lot of economic common sense leaves the discussion first. If I become a politician by promising you that you'll get your own personal doctor, for example, you aren't getting a real doctor - you are getting someone handed a doctor title but is really a naturopath, homeopath or whatever else that can be found cheap.

Being a woman is correlated to being twice as men to develop Alzheimer's disease, but lacking a scientific foundation for why, epidemiology is limited to noting it on a population level and moving on.

A new paper seeks to create a biological hypothesis. The authors say the C/EBPβ/AEP pathway is the core factor driving the pathogenesis of neurodegenerative diseases and searched for female hormones that are dramatically changed during menopause and tested which hormone selectively activates the C/EBPβ/AEP pathway. They have identified follicle-stimulating hormone (FSH) as the major pathogenic factor.

President Biden is touting his strong economic performance but the public disagrees; his approval rating is in the 30th percentile because an expanding economy as framed by politicians still means high inflation to people paying taxes. The psychological impacts of bad economic performance are evident also; when times are good, spending makes people happy. When times are bad, spending is stressful. Customers even leave worse reviews, according to a new paper.

Thankfully, most people who get COVID–19 don’t become seriously ill – especially those who are vaccinated. But a small fraction do get hospitalized, and a smaller fraction do die. If you are vaccinated and catch the coronavirus, what are your chances of getting hospitalized or dying?

As an epidemiologist, I have been asked to respond to this question in one form or another throughout the pandemic. This is a very reasonable question to ask, but a challenging one to answer.

One of the most important examples of early art in Europe, a 11 cm high figurine colloquially dubbed a 'Venus' and found in Willendorf, Austria, is made of a rock called "oolite" which is not found in or around Willendorf. 

New high-resolution tomographic images lead the authors to concluse the material from which the Venus was carved likely comes from northern Italy or possible eastern Ukraine, which sheds new light on the mobility of the first modern humans south and north of the Alps. 

For more than a century, journalism education prepared young people for the role of full-time professionals employed by sizeable news organisations. But the advertising-based business model that sustained journalism is collapsing because of new technology, and jobs of the old kind are becoming scarce. The educational model, too, must change to accommodate the new realities.

Eighteenth-century socialites have been depicted as vain, silly women who were poisoned by their white lead makeup. The Countess of Coventry, Maria Gunning — a society hostess renowned for her beauty — is said to have refused to stop wearing foundation containing white lead, even as she lay dying. Why would women of that era knowingly choose to wear makeup that was killing them? Was beauty worth dying for? Or was the makeup not to blame?

The behaviour of matter at quantum level includes a number of surprising effects, which we are lucky enough to be able to study and observe in different physical systems. Some of these effects are due to the radically different properties of particles endowed with integer amounts of spin (which we call bosons), and particles endowed with half-integer amounts of spin (which we call fermions).
