Eucalyptus trees are a pest-resistant evergreen that produce good lumber and oil that wealthy elites in the "wellness" marketplace buy - they are also an invasive species.

A new paper shows how scientists used CRISPR-Cas9 to knock out LEAFY, the master gene behind flower formation, so the trees will not reproduce sexually. The greenhouse study involved a hybrid of two species, Eucalyptus grandis and E. urophylla, that is widely planted in the Southern Hemisphere; there are more than 700 species of eucalyptus, most of them native to Australia.

Beer has been important throughout human history. Given how dangerous water was in the past, it is arguably true that civilization would not exist without beer.

Yet if you make your own, you have to think about waste. Spent grain, the malt and adjuncts left over from the mash, is 85 percent of brewing waste. If you don't have a compost pit or a farm somewhere close by, it's going inro the garbage.

Pilot results from San Bernardino County, California, where crime is prevalent and distrust in government high, found that religion may be key to COVID-19 vaccine uptake. Focused education efforts and an on-site mobile clinic in Black church parking lots resulted in the vaccinations of 417 people, 84% of whom were Black.

Results also showed an increase in Black attendance of mass vaccination clinics to 3.6% of total patients, up from 3%, in the week following asking Black churches and clergy to help in COVID-19 vaccination education and distribution.

What sets human communication apart from lower animals is its compositionality, which means that units of meaning can be combined and new meanings can be constructed. The words "blue" and "car" have their own meanings but combined there is a new content, i.e., a car that is blue.

Just a few short years ago, CRISPR-Cas9 technology took the world of molecular biology by storm because it allowed a cost-effective way to shut off or turn on traits in organisms without any side effects.

CRISPR is an acronym of Clustered Regularly Interspaced Short Palindromic Repeats, a bacterial defense system. The enzyme Cas9 acts like a pair of ‘molecular scissors’ that can cut two strands of DNA and insert of remove something. Then CRISPR repairs it.

Now it's gotten upgrade. Instead of one or two genes, a new study knocked out 12 at once.

Even previously considerate and helpful male managers have become less likely to mentor female employees, according to a new study. They've become less likely to even talk one-on-one with women.

This unintended consequence of the #MeToo movement could deny female employees critical development and thus career advancement. Women are not the problem, a large portion of female employees report a willingness to be mentored by an older male co-worker, but career advancement also has a social component, and in the last few years men are less likely to work one-on-one in an office with the door closed and less likely to engage in social behavior, like a post-work dinner with female employees.
