These tiny, suspended particles influence atmospheric processes, such as cloud formation and sunlight scattering. Now, researchers reporting in ACS Earth and Space Chemistry have shown that aphid-infes

Teens with opioid use disorder may benefit from medication treatment

Although the effectiveness of medications to treat adults with opioid use disorder has been well established, there has been little research about how — or even if — such treatment works in adolescents.Now, a new review of the literature suggests that, in addition to adults, adolescents with severe opioid use disorder can be treated with one of three medications: methadone, buprenorphine (Subute

Only a fraction of the costs of excessive drinking are paid for by alcohol taxes

The total harm caused by excessive alcohol consumption is a staggering $2.05 per drink in the United States, and, of this, the government ends up paying about $0.80 per drink.

This leaves the majority of the cost of alcohol's harms borne by those who don't drink ex

North Carolina Gives Republicans a Wake-Up Call

Why does election fraud happen? Because it works, of course. Usually it works because it’s undetected, and the candidate who commits the fraud, or on whose behalf it is committed, wins.

In a tight election, the Republican Dan Bishop, a state senator, beat the Democrat Dan McCready by ro

Ny studie: Därför går vi upp i vikt när vi blir äldre

Har det blivit svårare att hålla vikten i takt med att du blivit äldre? Du är inte ensam. En ny studie från Karolinska institutet visar nämligen att omsättningen av fetter, så kallade lipider, minskar i vår fettväv när vi åldras. Det tycks medföra just viktuppgång även om vi inte äter mer eller rör oss mindre.

Deciphering African late middle Pleistocene hominin diversity and the origin of our species

Nature Communications, Published online: 10 September 2019; doi:10.1038/s41467-019-11213-w Late Middle Pleistocene (LMP) hominin fossils are scarce, limiting reconstruction of human evolution during this key period. Here, the authors use phylogenetic modelling to predict the modern human last common ancestor’s morphology and inform hypotheses of human origins by comparison to LMP fossils.
