Bacterium Cupriavidus Metallidurans Can Turn Toxins into Gold

gold-producing-bacteria

Researchers at Michigan State University have discovered that the bacterium Cupriavidus metallidurans has the ability to withstand incredible amounts of toxicity, which is apparently key to creating 24-karat gold. Kazem Kashefi and Adam Brown found that the metal-tolerant bacteria C. metallidurans can grow on massive concentrations of gold chloride, a toxic chemical compound found in […]

Great White Shark Have a More Varied Diet Than Previously Thought

great-white-shark

It might seem that Carcharodon carcharias choose seals and sea lions as their preferred prey, but studies indicate that great white sharks consume different prey based upon their age, size and location. When they are juveniles, they seek out a wider variety of foods before culminating into the more well-known options. Scientists published their findings in […]

Images of the Necklace Nebula

necklace-nebula

The Necklace Nebula (PN G054.2-03.4) is a planetary nebula situated in the northern constellation Sagitta, and is located about 15,000 light-years away. It was first discovered by the Isaac Newton Telescope Photometric H-alpha Survey (IPHAS) in 2005. The mission is ground-based and focused on the North Galactic Plane. These composite images were taken by the […]

NASA Satellite Discovers a New Black Hole in the Milky Way

NASA's Swift Satellite Discovers a New Black Hole in our Galaxy

NASA’s Swift satellite detected high-energy X-rays a few degrees from the center of our galaxy, toward the constellation Sagittarius. Produced by a rare X-ray nova, this outburst announced the presence of a previously unknown stellar-mass black hole that is located 20,000 to 30,000 light-years away. “Bright X-ray novae are so rare that they’re essentially once-a-mission […]

Ketamine Produces Rapid Antidepressant Responses

ketamine vanquishes depression within hours

A recently published study shows that ketamine, a N-methyl-d-aspartate receptor antagonist, produces rapid antidepressant responses in patients who are resistant to typical antidepressants. Many chronically depressed and treatment-resistant patients experience immediate relief from symptoms after taking small amounts of the drug ketamine. For a decade, scientists have been trying to explain the observation first made […]

Scientists Explore How Order Emerges from Chaos in the Cosmos

how order arises in the cosmos

A newly published paper details how scientists created a model for exploring how electromagnetic fields help organize ionized gas in astrophysical settings, giving scientists a new way to explore how order emerges from chaos in the cosmos. Livermore, California — One of the unsolved mysteries of contemporary science is how highly organized structures can emerge […]

Combined Drug Treatment Delays Resistance in Melanoma Patients

Keith Flaherty

A recent study showed that using the combined treatment of kinase inhibitors dabrafenib and trametinib, while targeting different points in the same growth-factor pathway, delayed the development of treatment resistance in patients with BRAF-positive metastatic malignant melanoma. The results of a phase I/II study of treatment with the kinase inhibitors dabrafenib and trametinib were published […]

A closer Look at Interacting Galaxies

Interacting Galaxies

Scientists look at how galaxy collisions can distort the shapes of the galaxies involved, including the shapes and orientations of the regions around their central black holes, helping shed light on how infalling gas in a galaxy can efficiently feed its black hole, and whether light from the nuclear region is likely to be obscured […]

SSRL Validates Anti-Flu Protein Design

anti-flu proteins

A team of scientists designed proteins from scratch to have a high affinity and high specificity for targets on flu viruses, validating the two best designs using X-ray diffraction data collected at the Stanford Synchrotron Radiation Lightsource. Understanding why proteins interact with certain specific molecules and not with the myriad others in their environment is […]

Curiosity Prepares to Take its First Scoop of Soil for Analysis

Curiosity Prepares to Study Martian Soil

NASA scientists are preparing Curiosity to take its first scoop of soil for analysis, which will likely occur at the “Rocknest” site – a windblown, sandy and dusty location that is about 2.5 meters by 5 meters. Pasadena, California — NASA’s Curiosity rover is in a position on Mars where scientists and engineers can begin […]

“Arsenic-Life” Bacterium Prefers Phosphate Over Arsenate

gfaj-1

Researchers that claimed that the GFAJ-1 bacterium had a preference for arsenic instead of phosphorous in its DNA have been somewhat refuted. A new study shows that the GFAJ-1 microbe actually goes to extreme lengths to grab any traces of phosphorous it can find. This clears up one of the lingering questions, from a controversial […]

Paleontologists have discovered that horseshoe crabs haven’t had an entirely static evolutionary history. A new fossil has helped elucidate the mystery of the horseshoe crabs, which have been around for about 510 million years. The researchers published their findings in the journal Proceedings of the National Academy of Sciences. The fossil recorded a critical transformation […]

Faster Whole-Genome Sequencing May Lead to Routine Use in Neonatal Intensive Care

illumina-hiseq-2500

A new, faster DNA-sequencing machine, as well as streamlined analysis of its results, will allow physicians to diagnose genetic disorders in days rather than weeks. Up to a third of babies admitted to neonatal intensive care have a genetic disease, this may help pin down the genetic causes. The researchers published their findings in the […]
