21,848 363 Violent crime in large US cities dropped by about 4% on days with high pollen counts, likely due to the impact of seasonal allergies (n=19,752 days, 16 cities)
17,343 694 Study finds insufficient evidence of gaming as a clinical disorder. Rather than being negatively impacted by gaming itself, it’s suggested that young people who engage in dysfunctional gaming may be doing so in a bid to escape ““underlying frustrations and wider psychosocial functioning issues”.
42,292 2,054 Lab Grown Meat: Scientists grew rabbit and cow muscles cells on edible gelatin scaffolds that mimic the texture and consistency of meat, demonstrating that realistic meat products may eventually be produced without the need to raise and slaughter animals.
16,190 307 Scientists studying cuneiform tablets from Assyrian and Babylonian astrologers have found the oldest known mentions of auroras. The 2,700-year-old tablets refer to “red glows” or “red clouds” over the Middle East. The magnetic pole was closer to the region then, so northern lights were more common.
58,218 2,618 Doubting death: how our brains shield us from mortal truth. The brain shields us from existential fear by categorising death as an unfortunate event that only befalls other people.Being shielded from thoughts of our future death could be crucial for us to live in the present.
20,724 1,039 Being single beats being in bad relationships, and even neutral ones that aren't particularly bad, suggests new study.

6,242 593 30 healthy, non-smokers vaped e-cigs without nicotine or THC, and still experienced a measurable increase in lung inflammation after just 4 weeks of use. While the changes are small, this adds to evidence that vaping itself can alter the lungs, regardless of what's in the cartridge.
51,556 2,398 Both Democrat and Republican voters strongly support sex education in schools even though they disagree on other policies, suggests a new study (n=965), which found a strong majority of them support sex education and the continued funding by the government for teenage pregnancy prevention programs.
