A rare mutation that nearly killed a young girl has revealed insights into the common cold.
Researchers from the National Institute of Allergy and Infectious Diseases conducted a genetic analysis of a child who had been laid low by repeated bouts of rhinovirus (the virus that causes colds) and influenza infections severe enough to place her on life support. By combing through her genome, they found a single mutation that they say obstructed her bod ...read more

Paleontologists study creatures that have long ceased to be, all in the hopes of “resurrecting” the history of their lives on Earth.
But paleontologist Dean Lomax, an Honorary Visiting Scientist at the University of Manchester, has made a name for himself recreating a very specific part of ancient creatures’ lives: their final struggle before death.
Moments Captured in Time
Lomax has a keen eye for so- ...read more
More than 350 million years ago, our distant fishy ancestors traded in the life aquatic for land. Once ashore, these four-limbed vertebrates, called tetrapods, branched into an impressive range of animals: amphibians, reptiles, dinosaurs, birds and mammals. The fossil record shows that as species evolved to fill particular ecological niches, a few of the tetrapod clan lost limbs (snakes), turned arms into wings (bats, birds and pterosaurs) or decided the heck with dry land and headed back to sea ...read more
When we’re presented with a choice, we carefully weigh the alternatives and choose the option that makes the most sense — or do we? Only recently has science begun to unravel how we really make decisions.
In the face of stress or time pressure, or even seemingly unrelated cues, our assessment of situations and the choices we ultimately make can be colored by innate biases, flawed assumptions and prejudices born of personal experience. And we’re clueless about how they influence ...read more
Communities of tiny plants and organisms protect arid landscapes. Now their survival is threatened.
On a cool September morning, a caravan of international scientists rumbles past the iconic formations of Canyonlands National Park in Utah. Over the eons, wind and water have carved this landscape into a maze of stunning red sandstone arches and spires. The researchers marvel at the formations, so different from their own backyards — places as distant as China, Niger, Australia and Spai ...read more
