Algorithms teach computers how to process language. But because they draw on human writing, they have some biases. Researchers are trying to weed out those problematic associations.

Today is World Elephant Day, when people with a passion for pachyderms come together to celebrate the wonder of elephants and raise funds to protect them. It seems paradoxical that the largest land animal, which has come to symbolise strength and sagacity, should be so vulnerable but across Africa and Asia numbers are dwindling as human activities and expanding agriculture squeeze elephants into smaller and smaller patches of fragmented habitat.

To get a detailed look at how different proteins are folded, researchers freeze them in a crystalline structure and bombard them with extremely short bursts of x-rays. By recording how the x-rays bounce off the samples, scientists can reconstruct the different shapes—or conformations—that a protein can take. They then use a variety of techniques to determine how the proteins fold themselves into their final structures. But there are limits to these techniques that have caused most studies to focus on smaller, simpler proteins. The average protein found within a human cell, however, is neither small nor simple. Most are more like an economy-sized box of Christmas lights that have haven't been opened in a decade. In a new study, researchers at Duke University have taken a different approach to studying the conformations of one of these larger proteins. By slowly pulling apart a protein called Protein S, they discovered a previously unknown stable conformation made possible by a little help from its best friend. The results show that biochemists need to start rethinking some of their assumptions.

Killer whales in McMurdo Sound near the McMurdo Station, the National Science Foundation's (NSF) main logistics and research hub on Antarctica. NSF runs the U.S. Antarctic Program (USAP). In addition to maintaining three U.S. research stations on the continent, USAP supports research projects in an array of scientific disciplines, including for example, aeronomy and astrophysics, biology and medicine, geology and geophysics, glaciology, and ocean and climate systems. Outreach such as the Antarctic Artists and Writers program and education programs are also supported. For more information about USAP, visit the program's website here.

The world's population of elephants is nearing a critical point. Karl Mathiesen explains why there has never been a more dangerous time to be an elephant
The largest of all land beasts, elephants are thundering, trumpeting six-tonne monuments to the wonder of evolution. From the tip of that distinctive trunk with its 100,000 dextrous muscles; to their outsize ears that flap the heat away; to the complex matriarchal societies and the mourning of their dead; to the points of their ivory tusks, designed to defend, but ultimately the cause of their ruin.
