Dermatopathologists, skin cancer specialists, may be ordering additional tests or second opinions out of caution but they may also be thinking about checking off boxes to prevent malpractice lawsuits.

After centuries of converging on balanced, smooth beers, the industry suddenly lurched sideways in the 21st century. While large brands now have to fear for their existence, men in beards are making a fortune selling pronounced, bitter craft brews.

The business segment may have been with us all along, according to a new analysis. The survey of 109 beer consumers in a blind experiment found that greater perceived bitterness increased the appeal of beers. This is the opposite of most foods.

In some good news for 2020, it is confirmed that SARS-CoV-2, the 2019 form of coronavirus that has led to worldwide COVID-19 disease, is not transmitted by mosquitoes, so ecologically useless disease vectors like Aedes aegypti, that carry so many other diseases, can't get blame for the spread of this one during the summer season.

The World Health Organisation had already said mosquitoes did not transmit it, but they also claimed that it did not spread human-to-human and that China was a reliable source of data, so their credibility is suspect. While their hand-picked epidemiologists may trust the word of dictatorships, scientists elsewhere don't, so the new study is the first independent assurance that mosquitoes won't make this worse.

A new Hastings Report compilation is based on the notion that genomics are the reason we still have medical inequality. Since genomics is a field that exists to sequence our DNA content and therefore help understand disease, it seems odd to posit that it could promote inequality when studying biology we all share.

TikTok, the short video sharing app owned by Beijing-based ByteDance, has already been banned by the United States military, Wells Fargo, and the nation of India. A new report says no corporate phone, or private devices that may access secure information, should install it. 

From July 24, people in England will have to wear a face mask when inside shops, as well as on public transport. This brings England in line with many other countries that have similar rules already in place.

Bad things come in threes, it is said, and nothing shows that more than The Carnian Age; the first stage of three in the mass extinction era of the Late Triassic Epoch 228 to 217 million years ago.

It had three features; dramatic climate change with much higher humidity, the first dinosaurs appeared, and gigantic volcanic eruptions called the Wrangellia large igneous province spewed out greenhouse gases.

For dinosaurs, climate change was a good thing because plant life grew, thanks to the humid conditions and higher carbon dioxide. That event, now called the Carnian Pluvial Episode, may have been caused by the Wrangellia volcanic eruptions. The confluence of events seems to have spurred the early diversification of dinosaurs.

Throughout the last few decades health concerns related to air pollution have been rising. Despite this focus there has been little research on the impact of air pollution on specific health conditions and mortality, even though there is a strong association between air pollution and overall life expectancy. A global study lead by researchers in Germany outlines the detrimental changes air pollution can have on human life expectancy. One surprising finding of the study was that cardiovascular disease, and not respiratory conditions, are the primary cause of early death from air pollution.

How Bad is Air Pollution?

Social justice warriors in the feminist movement often fail to advocate for the rights of black women, according to new research, and it's for a reason that highlights hidden bias problems in modern performative activism - social justice for the Instagram photo - movement. Social justice warriors see black women as less like white women and more like black men.

A theorized particle process, called neutrinoless double-beta decay, could revise our understanding of ghostly particles called neutrinos, and of their role in the formation of the universe. But there is no evidence it actually exists.

The CUPID-Mo experiment is among a field of experiments trying to see if it does and preliminary results based on data collected from March 2019 to April 2020 set a new limit for the neutrinoless double-beta decay process in an isotope of molybdenum known as Mo-100. But not a single event was detected in CUPID-Mo after one year of data-taking.

Isotopes are forms of an element that carry a different number of uncharged particles called neutrons in their atomic nuclei.
