Protests in Charlottesville in the US turned violent recently, leading to the death of one person.
Our society is now intolerant of those who are intolerant of others; they can be legally penalised. But is that in itself a failure of tolerance?
Beijing residents with a variety of approaches to urban air pollution.
In recent years the number of motor vehicles – and the pollution they generate – has grown astronomically, leading some citydwellers to wear facemasks in the hopes of protecting themselves. So do they work?

We have an ethical obligation to stand against fascists and racists in a way that doesn't help them.
Assessing the data.
Evidence suggests that some chemicals can affect our bodies – even in very low doses. How can we better identify and act on these toxic materials?
The next frontier of data storage: DNA.
Researchers who hold the world record for storing and retrieving data in DNA explain how the building blocks of life can be used to hold digital information as well.
The cells inside this bioreactor are the real pharmaceutical factories.
Rather than being designed by chemists, this class of pharmaceuticals is produced by living cells. Here's where they come from and how they work.

A team of archaeologists strived to improve the reproducibility of their results, influencing their choices in the field, in the lab and during data analysis.
Friendship helps protect against loneliness even when oldsters do not have dementia. It can be especially beneficial for those who do.
A recent study finds that friends ought not let friends with dementia be lonely. The surprising part? Why staying friends is good for the friend without dementia as well as for the one who has it.
Students outside Columbine High School in Colorado in April 1999 following the mass shooting there. Some speculated that the shooters sought revenge for having been bullied.
Youth who are bullied may be at even higher risk than other youth for gun violence. These bullied youngsters were three times more likely to have access to a loaded gun, a recent study states.
What can a single person’s flu infection tell you about how the virus changes around the world?

Marriage has long been tied to better health. The first study of the relationship between marriage, health and quality of life for LGBT Americans affirms the benefits of marriage – with some caveats.
A subject plays a computer game as part of a neural security experiment at the University of Washington.
BCI devices that read minds and act on intentions can change lives for the better. But they could also be put to nefarious use in the not-too-distant future. Now's the time to think about risks.
Computers may play an important role in preparing us for the next viral outbreak – whether flu or Ebola.
UW Institute for Protein Design
This antivirus software protects health, not computers. Researchers are beginning to combat deadly infections using computer-generated antiviral proteins – a valuable tool to fight a future pandemic.
The latest tools in synthetic biology are allowing scientists to reprogram the immune system. Many studies on immunotherapy will be presented at the world's largest cancer meeting, which starts Friday.

A new research paper reports dangerous side effects in CRISPR-edited mice. Some scientists are pushing back, placing blame for the unwanted mutations on the experiment, not the technique.
Precision editing DNA allows for some amazing applications.
Researchers are starting to harness the potential of this much-hyped gene editing technique – with coming applications in medicine, biology and agriculture.
