Comparing the jaws of porcupine fish reveals three new species

Researchers compared fossil porcupine fish jaws and tooth plates collected on expeditions to Panama, Colombia, Venezuela and Brazil with those from museum specimens and modern porcupine fish, revealing three new species.

Boron nitride foam soaks up carbon dioxide

Researchers have created a reusable hexagonal-boron nitride foam that soaks up more than three times its weight in carbon dioxide.

Mystery of how first animals appeared on Earth solved

Research has solved the mystery of how the first animals appeared on Earth, a pivotal moment for the planet without which humans would not exist.

Using barcodes to trace cell development

There are various concepts about how blood cells develop. However, they are based almost exclusively on experiments that solely reflect snapshots. Scientists now present a novel technique that captures the process in a dynamic way. Using a 'random generator,' the researchers label hematopoietic stem cells with genetic barcodes that enable them to trace which cell types arise from the stem cell.

The key to drought-tolerant crops may be in the leaves

Scientists are exploring how to generate plants that are more drought-resistant as the water supplies decline in major agricultural states.

Seven complete specimens of new flower, all 100 million years old

A Triceratops or Tyrannosaurus rex bulling its way through a pine forest likely dislodged flowers that 100 million years later have been identified in their fossilized form as a new species of tree.

Frogs that adapt to pesticides are more vulnerable to parasites

Amphibians can evolve increased tolerance to pesticides, but the adaptation can make them more susceptible to parasites, according to a team of scientists.

Probiotics help poplar trees clean up contaminated groundwater

Researchers have conducted the first large-scale experiment on a Superfund site using poplar trees fortified with a probiotic -- or natural microbe -- to clean up groundwater contaminated with trichloroethylene, or TCE.

Seeing a virus in action

Imaging the movement of a virus demonstrates that single-particle X- ray scattering has the potential to shed new light on key molecular processes, like viral infection, when paired with powerful new algorithms.

Killing bacteria by hacking plastics with silver and electricity

Researchers have developed an innovative way of hacking conducting plastics so as to prevent bacterial growth using silver nanoparticles and a small electrical current. The method could prove to be useful in preventing bacterial infections in hospitals.
