High-tech ways to scan nature’s own creations.
Pharmaceutical companies focus on small molecules they've devised – and can easily patent. But nature's already come up with many antibacterial compounds that drug designers could use to make medicines.
In clinging to power, Nicolás Maduro, Hugo Chávez’s handpicked successor, is steering Venezuela’s once-rich democracy to autocracy.

The Mariana snailfish lives nearly 27,000 feet underwater, but has features that help it adapt to intense water pressure and cold. Physiological limits may prevent fish from surviving in deeper water.
Moving a robot is like manipulating a molecule.
Researchers use an algorithm designed to help robots move to figure out what's possible when designing new molecules in a promising class of pharmaceuticals.

In response to mudslides that have killed at least 20 people in Southern California, a geologist calls for more resources to study and map landslide hazards so residents can understand the risks.
The Arctic National Wildlife Refuge is home to a great diversity of wildlife – one reason environmentalists oppose oil and gas drilling.
US Fish and Wildlife Service
Alaska and oil proponents are cheering a move to open up an ecologically sensitive part of the Arctic National Wildlife Refuge to drilling -- a position environment supporters can't abide.
Twinkle, twinkle, little star…
The precious metal is literally extra-terrestrial, produced in the heart of the stars. How and under what conditions? Scientists know more thanks to a double astrophysical observation.
Delivering genetic material is a key challenge in gene therapy.

One of the best ways to shape public policy is for experts to submit detailed, technical information through the public comment process.
Le métal jaune est extraterrestre : l’or est produit au cœur des étoiles. Comment et dans quelles conditions ? Les scientifiques en savent plus grâce à une double observation astrophysique.
Wasteful and fake charities are usually harder to spot than this.
Digital innovations are making it easier to give to charity and for donors to become informed before they support nonprofits.
What can mating yeast tell us about new drugs?
By exploiting the way yeast cells mate, researchers have figured out a quicker, easier way to identify on- and off-target drug interactions.

On the 500th anniversary of the Protestant Reformation, two scholars explain how Luther's personal and spiritual life contributed to his success.
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.
